Description

Technical Field

[0001] This invention belongs to the field of foundation pit slope construction, specifically relating to a slope drainage hole opening and sand filling device and its construction method. Background Technology

[0002] To ensure the stability of the excavated slope, slope protection design is necessary. Slope protection with wire mesh and shotcrete anchors is the most economical and commonly used form of support for excavations. Drainage holes need to be left on the slope to drain water from the soil behind the shotcrete anchor support, preventing soil erosion and slope instability, and ensuring the stability of the shotcrete anchor structure. Currently, the drilling and sand filling of drainage holes on slopes are generally done manually, resulting in low efficiency and poor construction quality. Using large equipment, on the other hand, can easily disturb slope stability. Summary of the Invention

[0003] The purpose of this invention is to provide a device for opening and filling drainage holes with sand on slopes and its construction method. This invention allows for precise and labor-saving opening and filling of drainage holes with sand through manual operation, resulting in high construction efficiency, good quality, and no disturbance to slope stability.
