1. Earthwork excavation shall be carried out in strict accordance with the top-down procedure, and dangerous stones and landslides shall be removed before excavation. It is strictly forbidden to dig the slope into the reverse slope.
2. The excavation of landslide area should be carried out in layers from both sides to the middle and from top to bottom. It is forbidden to dig all trenches, and spoil shall not be piled up in the main sliding area. In the process of construction, there should be special personnel to observe and prevent landslides.
3. When digging near the edge of other buildings or poles, cables, wires, feng shui pipes, etc. , should formulate specific safety protection measures according to the actual situation, and assign special personnel to the scene to monitor and guide the operation.
4. Bad geological structures such as faults, cracks and fracture zones on the slope should be treated in time to avoid forming high slopes before treatment.
5. When excavating high slope by steps, protective measures such as slag retaining wall should be set on the construction platform or on the road.
6. The slope shall be constructed in strict accordance with the designed slope, and the slope shall be cut with the progress. It is forbidden to cut the slope after forming a large height difference.
7. Slope cutting and dangerous stone digging personnel must master the safe construction methods. It is forbidden to stand under the falling rocks that are easy to slide and dig, and it is forbidden to dig up and down on the same section at the same time. Excavation should be carried out during the day.
8. It is forbidden for personnel and machinery to enter the lower part of the excavation face. In addition to obvious safety warnings, special personnel should also be assigned for on-site monitoring.
9. With the excavation of high slope, it is necessary to follow up to form a slope drainage system to prevent the destruction of construction water, rainwater and groundwater, resulting in slope instability. Do a good job in excavation and protection. It is forbidden to dig the third layer before protecting the first layer.
10. Relevant safety measures should be taken around the excavation site of high slope, dangerous parts of working face, slag holes and caves, ground fissures and geological exploration holes that may be encountered, and safety signs and necessary safety protection measures should be set. If it is necessary to set up a security post, make sure that the duty is in place.
1 1. When entering the construction site, it is necessary to provide safe passage for the construction personnel. The upper and lower ladders should have handrails and anti-skid measures, and there should be a rest platform in the middle of the higher ladder. Illegal climbing is prohibited.
12. During the construction period, the slope stability should be closely monitored. If you find any abnormal changes, you should report them immediately. Weathered dangerous stones should be removed in time.
13. The width, slope and turning radius of the temporary motor road entering the working face shall meet the specification requirements. If there is any damage during construction, it should be repaired in time to ensure the safety of machinery and transport vehicles.
14. When building a machine lane on a steep slope, the safety of the machine must be ensured. If the working level of construction machinery is not up to standard, it must be repaired manually first, and mechanical operation shall not be forced.
15. It is forbidden to rest on dangerous slopes and cliffs. It is forbidden to build temporary facilities and houses under high slopes.
