With the arrival of the rainy season, these slope collapse prevention tips can be used!
[Repair measures for slope collapse] | Since the beginning of summer, thunderstorms, rainstorms, short-term heavy rainfall and other weather conditions will occur in many places. Under the influence of this unfavorable weather, some areas with complex geological conditions and dense forests may experience geological disasters such as landslides and mudslides, and may also cause highway slope collapse, which will have an adverse impact on people's travel convenience and life and property safety.
Today, the editor would like to talk to you about what effective prevention we can take to reduce unnecessary losses in the face of slope collapse when the rainy season comes.
Slope repair
First, remove the unstable soil on the slope, and then repair the slope according to the design. The soil on the slope must be backfilled and compacted with dry soil to ensure stability.
Artificially level the top of the slope and use fine stone concrete to seal the top. Set drainage ditches and water collection wells at the foot of the slope according to the design, and then remove the collapsed soil.
Slope reinforcement
A reinforced concrete retaining wall is set outside the bottom of the slope, and steel bars are set in the horizontal and vertical directions along the bottom of the slope, and concreting.
After the concrete strength reaches 75% of the required strength, straw bags are piled up from the bottom of the slope upward to support the slope wall. Simple sheet piles are added if necessary.
Wire mesh grouting concrete can be set under the top of the slope to close the slope wall according to the requirement.
Soil nailing and shotcrete construction
After the slope strength reaches the requirement, soil nailing construction is carried out according to the design requirements. A special construction plan and technical disclosure must be formulated. Before construction, the anchor rod and other materials must be tested for performance. They can only be used after test successfully.
After the construction is completed, the steel mesh is hung and concrete is shotcreted in time to reduce the exposure of the slope soil surface. |
Maintenance
The shotcrete surface should be water curing, preferably twice a day. When the temperature is too high or too low, moist covering maintenance and straw bag insulation maintenance should be carried out respectively.
Other relevant precautions
Drainage ditches and water collection wells must be set at the bottom of the slope, water retaining lines must be built on the top of the slope, and water collection pits must be set at the corners of the foundation pit. Heavy vehicles are prohibited from passing near the top of the slope during construction. Safety guardrails must be installed during construction on the top of the slope. Warning signs must be set up during nighttime construction to ensure adequate lighting and red warning lights. Standing under the slope is strictly prohibited, and unrelated personnel are strictly prohibited from entering the working range. Top of the slope
Sedimentation plates are buried at the top of the slope, with points arranged every 20m. Horizontal displacement monitoring is measured once a day during excavation, once 3 to 7 days after stabilization, and once 7 to 14 days after bottom sealing. Sedimentation monitoring is measured once 1 to 3 days during excavation, once 3 to 7 days after stabilization, and once 7 to 14 days after bottom sealing.
Slope protection
Deformation monitoring points are arranged on the slope, with points arranged every 20m. Measure once every 3 to 7 days during excavation, and once every 14 to 28 days after bottom sealing. |  |
[How to effectively prevent slope collapse] | Surrounding buildings
Two observation points are arranged for each building. During excavation, the drilling is conducted once every 3 to 7 days, and after the bottom is sealed, the drilling is conducted once every 14 to 28 days. The series of anchor drilling rigs manufactured by ZSIM is an integrated slope management anchoring equipment specially developed for various mountain slopes. The drill rigs are applicable in geotechnical engineering such as highway and railway mountain slope with anchor cable reinforcement.
In recent years, the ZSIM series anchor face drilling rigs have become the preferred equipment for slope disaster treatment due to its wide range of applications, and its market share has been rising steadily. The drill rigs have been participating in slope disaster construction projects in many regions at home and abroad. |
