How to do the foundation groove inspection record data

Requirements for filling in foundation groove inspection records:

1. The acceptance time is the date of joint inspection and acceptance by all parties.

2. The location, geometric size and elevation of the foundation groove (pit) are filled in according to the acceptance and measurement records.

3. The changes in the direction, thickness and soil quality of the soil layer are illustrated by diagrams.

4. The type, color and hardness of the soil at the bottom of the trough.

5. Groundwater level and flooding, etc.

6. In case of ancient burial mounds, cobalt wells, caves, cables, old house foundations, and quicksand, etc., the location, elevation, treatment description or change document number should be indicated in the drawing.

7.Inspection and acceptance opinions: indicate whether the foundation meets the relevant requirements such as design and specifications. Whether it is related to geological exploration.

The soil condition in the report is consistent with the situation, and the groove inspection is carried out by the construction unit.

Organize geological exploration departments, design institutes, construction, supervision units and construction related personnel to participate, and jointly inspect and make records and sign. The construction of the next process shall not be carried out without the groove inspection procedures.

Foundation Groove Inspection Procedure:

1) On the basis of the self-inspection of the construction unit. The construction unit confirms that the self-inspection is qualified and submits an acceptance application;

2) The project leader and technical quality person in charge of the construction, supervision, survey, design and construction unit shall be organized by the chief engineer or the project leader of the construction unit, and shall jointly carry out the project in accordance with the design requirements and relevant regulations.

Foundation groove inspection method:

1) The observation method is usually used for foundation inspection.

For the invisible parts of the soil layer below the substrate, brazing is usually used.

Law. 2) Light dynamic penetration probing.

When one of the following situations is encountered, light dynamic penetration should be performed on the substrate:

1) Holding layer.

Noticeable unevenness;

2) there is a weak substratum in the superficial part;

3) When there are shallow pits, ancient tombs, ancient wells, etc., which are difficult to find by direct observation;

4) When the survey report or design document stipulates that light dynamic cone penetration should be carried out.

Foundation inspection and foundation treatment:

After the local abnormality of the bottom of the trench is found through the inspection of the groove and the analysis of the drilling data, appropriate treatment methods should be adopted according to the soil conditions, engineering properties and construction conditions of the foundation soil to reduce or avoid the uneven settlement of the foundation.

1) Treatment of local hard soil: dig out the hard soil part to avoid uneven settlement. When processing, the backfill material should be determined according to the soil quality of the surrounding soil, and if it is difficult to excavate all, make a soft cushion layer on its upper part.

treatment, so that the foundation settles evenly.

2) Treatment of local soft soil: due to the influence of external factors (such as pipeline water seepage), formation differences or water content in the foundation soil.

The change of the local soil quality of the foundation is quite different. If the thickness of the soft soil is not large, it is usually treated by the soil replacement cushion method to remove the soft soil, and graded sand and gravel are generally used.

Cushion, compaction factor.

Not less than; When the thickness is large, on-site bored piles are generally used.

Concrete or block stone support walls (or buttresses) to bedrock for local foundation treatment.

Example of filling in the foundation groove inspection record data:

Fill in the acceptance content as follows:

1.The excavation depth is to the design elevation, and the foundation soil is the first layer of soil, which is consistent with the exploration report.

2.The foundation is a strip foundation, the foundation groove adopts large excavation, and the elevation of the bottom of the foundation groove is meters. Meet the design requirements.

3.The position and geometric dimensions of the axis of the foundation groove meet the requirements of the design drawings.

4.The original ground elevation is so the actual excavation depth is meters.

It is best to pay a foundation pit profile later.

Fill in the inspection record of foundation pit (groove) excavation construction

1. Header part: number, project name, date.

2. Basis and content of line inspection: one basis (the positioning control pile has several axes, municipal coordinate control point BM, foundation plan), two contents (base outer contour line and outline section, cushion elevation, sump, elevator shaft and other cushion elevation and position.

3. The foundation groove plane and section drawing (the four corners of the building are represented by a simple drawing) are required to be described in the construction drawing.

4. Inspection opinions: whether it meets the design requirements and how much the elevation error is. 5. Signature column: construction, design, supervision, construction unit (project manager, technical leader, professional quality inspector, tester).

Introduction. The purpose of foundation excavation is to excavate weathered, broken, defective and weak rock formations, soft soil and alluvium that do not meet the design requirements, so that the building can be built on a reliable foundation; Or according to the requirements of the structural design, in order to build the building on a specified elevation. The specific construction methods of foundation excavation, including loosening, blasting, excavation, loading, transportation, slag unloading and other processes, are the same as general earth and stone excavation.

Before construction, the construction organization design or construction technical measures should be prepared according to the building conditions, topographic and geological conditions, hydrometeorological data, construction period requirements, etc.

Summary. Hello, according to your question description, the answer is as follows: generally after processing, the foundation brazing, bearing capacity are completed, the width and depth of the foundation groove and the soil quality meet the requirements, and the groove inspection is actually a necessary procedure before the foundation construction.

I hope my answer can help you.

Engineering data: The filling time of the groove inspection record should be before or after the foundation treatment, that is, whether the groove inspection is before or after the foundation replacement.

Hello, according to your description of the problem, the answer is as follows: generally after the treatment, the foundation brazing is completed, the bearing capacity is completed, the width and depth of the foundation groove and the soil quality meet the requirements. I hope my answer can help you.

State Mega. The acceptance record of the foundation groove should be filled in by the quality supervision unit after the acceptance of the foundation groove (or you fill in their signature and seal, it doesn't matter who fills in) the acceptance of the foundation groove, and Party A and Party B will put forward the treatment opinions and treatment plans of the foundation groove! And after processing, the second acceptance will be carried out! If the foundation groove is fully compliant, the situation that meets the requirements will be indicated, and the joint signature will be included in the file side case information!

Reminder: If you are drilling, the data clerk Yun Han guesses to prepare the "Exploration Hole Plane Distribution Map" and attach a list of the depth of the exploration holes, and number the reference when the groove is to be inspected. I hope my answer can help you.

The foundation groove inspection record, this is a must-have, and then come to participate in the design, survey, construction, supervision, and construction unit of the groove inspection unit to sign.

The main purpose of foundation trench inspection is to see whether the situation of the soil layer is consistent with the geological exploration report after the earthwork is excavated to the design elevation. Most of the time, if there is no special situation, the groove inspection is just a formality and a completion of the groove inspection procedures.

There is a foundation groove inspection record in the construction management data, which is printed out and filled in, and the engineering geological survey report should also be prepared for future reference.

After the large-scale excavation of the lot, there is a geological situation that does not match the geological report, or after the excavation, the foundation groove has slurry or silt due to rainfall, resulting in soft soil, which can not be directly stressed, and needs to be cleaned up again, at this time, it is necessary to inspect the groove.

The inspection should be divided into two phases.

First, the internal inspection after the excavation of the foundation groove is manually cleaned, mainly in the self-inspection groove before the surface layer of the subsoil is dried, because at this time, the color change of the soil quality of the foundation groove is the easiest to identify, and it is easiest to find whether the soil quality of the bearing layer is uniform, whether there is any abnormal situation, etc.; At the same time, the acceptance of the elevation of the foundation groove, the size of each part, the flatness of the base, etc., to see whether it meets the requirements of the drawings and specifications.

Second, after the brazing, there is a joint inspection of the construction unit to organize the design, geology, supervision and construction unit, and its purpose is basically the same as the previous one, of course, the brazing record is also one of the bases for judging the homogeneity of the foundation; It is a necessary procedure for the construction of the next process.

Summary. Dear, hello and glad that your question is whether the pile foundation needs to be inspected whether the groove needs to be inspected or not, the foundation groove inspection record is required: the pile foundation does not need to be inspected, the pile head is cleared, and the foundation groove inspection record needs to be done after the earthwork excavation is completed.

Does the pile foundation need to be inspected? Do I need to do a foundation groove inspection record?

Dear, you are happy to answer your question whether the pile foundation needs to be inspected whether the groove needs to be done or not: the pile foundation does not need to be inspected, the pile head is cleared, and the foundation groove inspection record needs to be done after the earthwork excavation is completed.

Extended information: (1) The construction of cast-in-situ concrete wall protection method is sectional excavation and sectional pouring of concrete wall protection, which can not only prevent the collapse of the hole wall, but also play a waterproof role. The pile hole is excavated in sections, and the height of each section depends on the ability of the upright state of the soil wall, which is generally a construction section, and the diameter of the excavation hole is the design pile diameter plus the thickness of the concrete retaining wall.

The construction section of the retaining wall, that is, pouring concrete after supporting the template (tool-type movable steel formwork) in the retaining wall, its strength is generally not less than C15, and the concrete of the retaining wall should be vibrated and compacted; When the concrete strength reaches 1MPa (about 24h at room temperature), the formwork can be dismantled and the next construction section can be entered. This is done until the depth required for the design is reached. Naibi (2) caisson wall protection method construction when the pile diameter is large, the excavation depth is large, the geology of Changdanju is complex, the soil quality is poor (soft and weak soil layer), and the groundwater level is high, the caisson wall protection method should be used to dig holes.

The caisson wall protection construction is to make the reinforced concrete wellbore on the pile position first, the reinforced concrete cutting edge foot is pounded under the wellbore, and then the soil is dug and hollowed out in the bore, and the wellbore relies on its own weight or additional load to overcome the frictional resistance between the cylinder wall and the soil, and sinks while digging, so that it sinks vertically to the depth of the design to be delayed.

First of all, check whether the position, size and depth of the foundation groove are consistent with those on the design drawings; Secondly, check whether the soil quality and groundwater of the tank wall and bottom of the tank are consistent with the survey report; Then check whether there are other old buildings in the foundation groove, such as ancient wells, ancient tombs, etc.; Finally, check the distance between the edge of the foundation groove and the nearby buildings, and whether the excavation of the foundation pit has an impact on the building.

The soil layer is divided into clay, sand, mudstone, etc., and the bearing capacity of the same soil layer is different, such as the bearing capacity of gravel soil layer is stronger than that of peat. Therefore, when laying the foundation, it is necessary to choose the soil layer with good bearing capacity; Secondly, it is necessary to see whether the foundation is in a river or debris flow disaster area. Avoid the subsidence of the foundation in the later stage and affect the stability of the house.

0. Whether the stratum condition is consistent with the survey report, whether the bearing capacity of the substrate reaches the value mentioned in the survey report, etc., generally I go to the tank to see these.

1. Plane size, elevation.

2. The geological conditions, whether the rock and soil are consistent with the design and survey conditions, whether the basement soil layer is uniform, and whether there is water seepage.

3. Whether there is artificial disturbance in the base, whether there are underground buildings or backfills such as ancient tombs and civil air defense projects. substrate drainage, etc.

(1) Check the excavation plane position, size, and bottom depth of the foundation groove according to the design drawings, check whether it is consistent with the design drawings, and whether the excavation depth meets the design requirements.

2. Carefully observe the type and uniformity of the soil at the bottom of the groove and whether there is any abnormal soil quality, and check whether the soil quality and groundwater of the foundation pit are consistent with the survey report

3. Check whether there are old building foundations, ancient wells, ancient tombs, caves, underground burials and underground civil air defense projects in the foundation groove.

4) Check the distance between the outer edge of the foundation groove slope and the nearby buildings, and whether the excavation of the foundation pit has an impact on the stability of the building.

5. The natural foundation groove inspection should be inspected, verified, and analyzed by brazing data, and the abnormal points should be reviewed and inspected. Pile.

The base should be tested to see if the quality of the stake is qualified.
