What should I pay attention to at the foundation construction site in building construction?

1. Selection of foundation construction technology.

Before foundation construction, it is necessary to develop a reasonable construction technology according to the details of the construction site. Because the construction technology used for different foundation properties is different, the water quality status, climatic conditions, and surrounding environment of the site are investigated and understood in detail, and then a reasonable construction technical plan is formulated according to the existing technical force of the project and the condition of the machinery and equipment. The selection of construction technology must be adapted to the site conditions to ensure the construction quality of the foundation.

2. Design of foundation construction technology.

After the investigation and analysis of the site, the designer asks the construction personnel to formulate reasonable construction procedures. According to the actual situation, the designer formulates the construction materials and equipment deployment required in the project, and selects the best design plan after comparing and analyzing a variety of design schemes. Small-scale experimental analyses are then carried out to determine the correct construction procedure.

3. Strengthen the preparation work before the construction of the foundation.

After the foundation construction plan is determined, sufficient preparations should be made according to the construction status of the project, and according to the needs of the construction technology, the materials needed in the construction should be arranged, the transportation arrangements of vehicles, the arrangement of personnel and the coordination with relevant departments and so on. Only when the materials are sufficient, the machinery and equipment and personnel are complete can the construction be carried out to ensure the smooth progress of the project.

4. Problems that need to be paid attention to during and after foundation construction.

The quality of foundation construction is an important guarantee for the construction quality of the main body of the building, on the way of construction, technical personnel need to speed up the construction personnel's understanding of the foundation construction technology, assist the construction personnel to control the construction process, technical standards and quality requirements of the foundation construction technology, and do a good job of monitoring and improving the detection of construction effect on the way to construction. Compared with those high-rise buildings with higher quality requirements, the test and inspection work must be done in advance, and the design and accounting should be carried out after the construction is completed, so as to minimize the existence of problems and absorb detailed information, so as to provide more information for the next step of construction, and improve the quality of foundation construction of high-rise housing buildings as much as possible.

Pay attention to safety, protective measures should be appropriate, construction technology and work process should be reasonably arranged.

and establish a series of protective measures.

Upstairs... How could the pile hole fall. Fainting. I feel that the key point is that the concrete is not intermittent. Otherwise, the stake will be broken. It's time to fill the pile.

If rural people want to build their own houses, they generally choose to build their own houses, but when they build houses, they first have to lay the foundation. A step like this is a very important step, and it is also the first step, when laying the foundation, everyone will think that as the saying goes, the foundation will shake if it is not firmly laid. Such a foundation refers to the foundation when building a house, and for safety and more comfortable living in the future, it is also better to connect on the ground.

If the foundation is not firmly laid, the mountains will shakeMany people may choose to let some contractors lay the foundation during the construction process, but some contractors may say better before construction, but there is some laziness during construction. Therefore, in this case, it is recommended that you have a deeper understanding of the foundation before you can better prepare the foundation for your self-built house. First of all, if you look at the types of foundations, they are actually divided into four types.

In the process of construction, the foundation is laidFirst of all, there is an independent foundation like this one, which does not require piling, and the construction is very simple in the whole process。But there is a disadvantage that it may not be as stable as some other types, so it is not suitable for the foundation of such a house for self-built houses. In addition, the second type is a kind of foundation like a strip foundation, which is very commonly used in rural areas, and it has many advantages in terms of advantages.

The strip foundation is very practical, first of all, its bearing capacity is very good, and it will not be deformed under normal circumstances, and the overall cost is also very low, which is relatively economical and practical. For many homes, you can choose a strip foundation like this, but there may be some safety hazards in the future, that is, some wall cracks may occur. Then there is a kind of foundation that belongs to the pile foundation, and it also has certain restrictions on such a foundation, because it is mainly aimed at some homesteads where the soil quality may be poor.

How to lay a foundation on soft soil is really a university question.

Building a house is a hundred-year plan, and it can't be perfunctory. First of all, the depth of the foundation must be more than 1m. Second, the foundation of the trench type should be opened. You can't just do a few points like a dragonfly. With such a foundation, the house can be solid and solid.

We should pay attention to the choice of materials, and we should look at the groundwater, but also the thickness of the soil layer, and we should pay attention to the quality of the soil.

When working on foundation design, consider:

The pressure per unit area of the bottom surface of the foundation is less than the allowable bearing capacity of the foundation.

The settlement value of the building is less than the allowable deformation value.

There is no danger of slipping the foundation.

On the basis of the three links and one level of the site, according to the data of the building measurement and control network and the foundation layout plan, the grid control network and the elevation datum point of the pile axis were determined. Determine the center of the pile, take the center as the center, and draw the circumference of the upper part (i.e., the first section) with the radius of the pile body and the thickness of the wall as the radius. The lime line is sprinkled as the pile hole excavation dimension line.

And along the center position of the pile to the pile hole to lead out four pile axis control points, with a firm wooden pile calibration. After the pile line is set, it must be reviewed by the relevant departments and excavated after completing the pre-inspection procedures.

1.The soil quality of the foundation must be good Building a house is the same as planting crops, if the soil quality is not good, the house built will not be firm. So when my family was building the house, in addition to digging the foundation trench, they also filled the trench with a lot of bricks and stones, and used a tamper to tamp it layer by layer.

2.Will pick a good day In our place, we pay great attention to picking a day for important matters, and we will ask a fortune teller to help you choose a suitable day according to the family's physiognomy and then start work.

1. The foundation is a piece of land located under the foundation, which is only responsible for dispersing the load from the foundation to the earth's crust, it is not a component, if the foundation is not placed there, then it is just ordinary land;

2. Site leveling Before construction, the construction unit shall complete the work of three links and one leveling. Coordinate and solve the obstacles, underground pipe networks and obstacles encountered by machinery and equipment entering the site Before construction, the construction unit shall provide information on the underground pipe network and obstacles on the site, so as to make corresponding adjustments during construction.

Design changes must be made when problems occur. Common practice: adjust the basement floor practice to reduce its thickness; Strengthen the quality control of the flatness of the basement roof formwork, etc., and the bottom of the slab is no longer plastered; 0 000 elevation increase, etc.

Take the above several ways to make comprehensive adjustments to ensure the indoor clear height of the basement.
