1, construction preparation, the project will build a material transportation road, thus making the transportation of the project more convenient.

2. During trench excavation, temporary drainage ditches should be set at the sidewalk during construction to ensure smooth drainage and ensure that the excavated foundation pit will not be soaked by rain and cause foundation pit quality problems. During foundation pit excavation, small earth dikes should be built on both sides of the trench to intercept water and prevent surface water from flowing backwards into the trench. There are drains and water storage wells on both sides of the groove, which are filled with gravel. When the groundwater is rich or rainy, pump water.

3, drainage pipeline construction, with excavator excavation, artificial cooperation. Trench excavation earthwork shall be transported to fill area or dump truck for detailed disclosure. In the process of digging, managers should command at the scene, and often check the clearance size and center position of the groove to ensure that the deviation error of the groove center meets the specification requirements.

4. When backfilling the pipe pit, the sand cushion should be gravel, and the sand should be mixed well before laying. When paving the cushion, the border inspection should be done first.

5. During subgrade construction, earthwork excavation shall be carried out from top to bottom according to the design requirements, without indiscriminate excavation and overbreak. Effective measures shall be taken to ensure the safety of local residents and construction personnel along the village crossing and within the residents' scope, and access roads and temporary bridges shall be provided at necessary crossings.

6. During pavement structure construction, bulldozer paving, grader leveling, sprinkler sprinkling, rolling and sand filling are used to test the compaction effect.

Precautions for construction safety:

1. Conduct education and assessment on construction safety and fire control knowledge. Employees who fail to pass the examination are prohibited from entering the construction site to participate in the construction.

2, enter the construction site must wear a helmet, fasten the hat belt, the correct use of personal labor protection articles.

3. Strictly implement the operation procedures, and shall not command or operate illegally, and have the right to refuse and have the responsibility to stop others from operating illegally.

4. Personal protective equipment must be worn correctly during construction, and safety helmet must be worn when entering the construction site. Don't use fire without permission, and don't operate after drinking.

5, are not allowed to wear slippers, high heels, barefoot or shirtless into the construction site.

6, wear hard shoes may not be climbing operations.

7, high altitude, steel, structural operations, be sure to wear non-slip shoes.
