What details should be paid attention to in the construction technology disclosure?

The content of the construction technology disclosure is mainly composed of the following parts: 1. Overview of the project. 2. The construction method and the quality requirements of each process.

3. Geometric size or elevation. 4. Construction safety measures and precautions. The following is the technical disclosure of culvert waterproofing.

Project name: reinforced concrete cover plate box culvert.

Disclosure location Disclosure time.

Disclosure content culvert settlement joints and waterproof layer construction.

First, the general situation of the project.

The culvert center mileage reinforced concrete cover plate box culvert, culvert length, for the interchange, the use of separated foundation, culvert foundation under the 10cm thick gravel cushion.

2. Settlement joints and waterproof layers.

1. Settlement joint: the width is 3cm, and the surface of the joint is paved with a wide layer of asphalt-impregnated linen and a waterproof layer of two layers of asbestos asphalt. At the joints below the waterproof layer, the outer side is filled with asphalt soaked hemp tendons with a depth of 5cm, and the inner side is filled with M10 cement mortar with a depth of 15cm.

The settlement joints of the foundation part do not need to be filled, leaving the asphalt-impregnated wood board embedded during construction and doubles as waterproofing (if the wooden board is not used during construction, it can be filled with clay).

2. Waterproof layer: from the top surface of the cover plate to the bottom surface of the cover plate below the two sides of the side wall outside the A waterproof layer, first coated with two layers of asphalt paint, and then paved with asphalt impregnated linen cloth and asbestos asphalt two layers, the waterproof layer must be smeared with a 3cm thick asphalt concrete protective layer. Use the top surface and both sides of the culvert with a waterproof layer and other culverts, and apply impervious soil outside the waterproof layer to make a long protective layer with a thickness of 15 20cm, and when there is a lack of impervious soil, it can be exempted.

3. Quality requirements.

1. Settlement joint perception quality standards.

The seam body is vertical, the seam width is basically uniform, the circumferential direction is through, the filling is dense, and there is no water leakage.

2. The waterproof layer should meet the design requirements, with waterproof, durable, firm bonding and necessary elastic toughness.

Fourth, do a good job in on-site safety, civilization and environmental and water protection construction.

Review: Informant: Receiver:

Construction according to the construction technical specifications, as well as the construction process!

The content of the construction technology disclosure is as follows:

1. Relevant content in the site disclosure: such as whether there are construction conditions, cooperation and contradictions with other types of work, etc., put forward requirements to Party A and let it come forward to coordinate.

2. The construction scope, engineering quantity, workload and construction progress requirements: mainly according to their actual situation, they can explain to Party A in a realistic manner.

3. Explanation of construction drawings: the general idea of the designer, as well as the problems existing in the construction in the future.

4. Construction plan measures: according to the actual situation of the project, prepare a reasonable and effective construction organization design and a safe and civilized construction plan.

5. Operation technology and measures to ensure quality and safety: advanced machinery and equipment and high-quality workers.

6. Process quality standards and evaluation methods: refer to the current industry standards and the corresponding design and acceptance specifications.

Disclosure form

1. The construction organization design disclosure can be made in the form of convening a meeting, and the meeting minutes should be archived.

2. Through the preparation and approval of the construction organization design, the technical disclosure content is incorporated into the construction organization design.

3. The construction plan can be technically disclosed in the form of convening a meeting or on-site teaching, and the content of the disclosure can be included in the construction plan, or it can be formed separately.

4. Each professional and technical management personnel shall make a technical disclosure in written form with on-site oral lectures, and the content of the technical disclosure shall form a separate disclosure document. The content of the disclosure shall have the date of disclosure, the signature of the person who made the disclosure and the recipient, and shall be approved by the chief engineer of the project.

1. In addition to comprehending the design intent, it is necessary to meet the requirements of design drawings and changes, and implement and meet the reasonable requirements of construction specifications, procedures, process standards, quality assessment standards and construction units.

2. The entire construction process, including the construction of each sub-project, must be made a technical disclosure, and the technical disclosure should be made seriously for some special key parts and concealed projects with great technical difficulty.

3. For the types of work and engineering parts that are prone to quality accidents and industrial accidents, the preventive measures for various accidents should be emphasized in the technical disclosure.

4. The technical disclosure must be in writing, and the handwriting of the disclosure content should be clear and complete, and the person who made the disclosure and the recipient must sign it.

5. The technical disclosure must be carried out before the construction of the project, as part of the preparation for the construction of the whole project and the sub-project.
