Anti slide pile is a pile that passes through the landslide mass and goes deep into the sliding bed to support the sliding force of the landslide mass and stabilize the slope. It is suitable for shallow and medium thick landslides. It is a main measure of anti slide treatment.
But how can we dig out a square pile hole with a section of 2 * 3M and a depth of more than 10m in a low-cost and efficient way?
The solution we give is the combined construction scheme of special auger and drum cutter.
Firstly, a roughly rectangular pile hole is excavated by array excavation with auger. Remove excess debris and drain the accumulated water.
After the excavator links the extension rod, it is equipped with Yichen drum cutter. The rough hole wall is trimmed by the drum cutter to make it a plane.
Hoist the prefabricated reinforcement cage with a crane and fix it with the hole wall.
Finally, cement pouring shall be carried out. In the previous excavation process, the construction waste obtained can be used as backfill material after crushing and screening by Yichen screening bucket, so as to save the cost of waste treatment and filling materials.
