Construction technology and safety measures in rainy season?

What are the construction techniques and safety measures in rainy season? The following is a detailed introduction of Zhong Da Consulting for your reference.

1, use

In order to ensure the normal construction in the rain period and ensure that the progress, technical quality and safety of the project in the rain period meet the specified requirements.

2. Scope of application

Applicable to all projects under construction undertaken by the Company.

3. Responsibility

3. 1 The production management office of the branch company is responsible for the formulation and centralized management of technical measures for construction in the rain period. According to the actual situation of the project and the measures formulated by the branch, the project department formulates specific implementation measures and supervises their implementation.

3.2 The production office of the branch is responsible for the implementation of construction measures in rainy season.

3.3 ministry of materials and equipment is responsible for the rainy season protection of materials in use at the construction site and the supply of waterproof and flood control materials, while ministry of materials and equipment is responsible for supervising the implementation.

3.4 The production management office is responsible for the safety inspection and acceptance of the construction site in the rain period.

3.5 The Equipment Department is responsible for the supervision and inspection of rain-proof and moisture-proof mechanical and electrical equipment on the construction site.

3.6 The project department shall implement the measures formulated by the company and its subsidiaries, organize their implementation, pay attention to the weather forecast of the local meteorological station, grasp the weather changes and take corresponding measures.

4. Measures

4. 1 Preparation before construction in rainy season

4. 1. 1 Before the arrival of the rain period, the branch and the project department should conduct a comprehensive inspection of the construction site, establish and improve the responsibility system for construction quality and safety in the rain period, designate a person to be responsible for the implementation of the construction in the rain period, set up a leading group for flood control, and organize forces to maintain and dredge the drainage system of the construction road to ensure that the road is smooth after the rain and the rainwater is discharged in time.

4. 1.2 Conduct a comprehensive inspection and maintenance of the temporary houses on site.

4. 1.3 prepare necessary flood control and drainage machinery and materials according to the actual situation of this project.

4. 1.4 Listen to the weather forecast at any time, and prepare for rain and drainage. When problems are found, they should be solved in time and recorded.

4.2 Technical measures

4.2. 1 When preparing the construction organization design (or scheme), specific waterproof and drainage technical measures should be taken for the construction project in the rain period.

earthwork

A, in the rain period excavation of foundation pit (ditch) or pipe trench, should pay attention to the slope stability, gentle slope or support when necessary.

B, after the foundation pit (groove) excavation, the drainage ditch, sump and drainage ditch should be excavated at the bottom of the pit, and a water retaining line should be set along the pit to prevent rainwater recharge.

C, completed foundation, pipeline engineering should be timely backfill, compaction, and higher than the natural ground, and make a certain slope, to facilitate the drainage of rainwater.

D, the rain period construction face should not be contiguous, should be completed by stages, and try to avoid important or special earthwork.

E. Necessary flood control measures should be taken for construction in areas close to mountains and waters.

4.2.3 Structural hoisting works

The site for stacking components should be flat and solid, and have good drainage measures. When stacking components, there should be a certain gap between components and the ground.

4.3 Safety measures

4.3. 1 When excavating deep foundation. Slope setting or slope solid wall support should be carried out in strict accordance with the provisions of the construction organization design, and often checked during construction. If deformation, landslide and cracks are found, they should be reinforced immediately without negligence.

4.3.2 Scaffolding, ramp, etc. in use. Anti-skid measures shall be taken, and protective railings shall be provided for each working area and passage. After the heavy rain, scaffolding, temporary support, etc. Should be checked and recorded. If the cable is found to be sinking, inclined or loose, measures should be taken immediately, otherwise construction may not be carried out.

4.3.3 In case of gale and thunderstorm of magnitude 6 or above, aerial work and component hoisting should be stopped, and it is forbidden to work under high-voltage lines and shelter from rain near poles and transformers.

4.3.4 All electrical equipment on the site must have a solid waterproof box cover, and the wires cannot be pulled randomly, let alone rolled locally; Fixed and non-fixed electrical equipment in use must be connected to zero protection. Mobile and rolling electrical appliances should be equipped with leakage protectors, and the leakage protectors should be checked frequently to ensure good performance and normal use.

4.3.5 Fixed machinery used on site, such as plate bender, press, radial drilling machine, etc. , should be covered with protective shed, mobile transportation machinery should be equipped with rain cover.

4.3.6 Before the project starts, the builder shall make safety technical disclosure to the team, and put forward targeted safety precautions in rainy season according to the characteristics of divisional and sectional projects.
