[0073] The method of running mortar for planting precast piles in gravel layers adopts the following steps:
[0074] Step 1: Fabrication and transportation of precast piles.
[0075] Make precast square piles in the precast pile factory and transport the precast piles to the pile planting site.
[0076] The length of the precast square pile is 24m, and the side length is 700mm×700mm.
[0077] The prefabricated square piles are provided with hoisting rings for loading and unloading with equipment.
[0078] Step 2: Measure the laying-out and hole planting.
[0079] Use the total station to determine the hole position of the precast pile and construct the guide groove of the precast pile position; use the dual-power-head long auger drill to drill the hole with a hole diameter of 1100mm. When drilling to the gravel soil layer, use the drill to follow the drill bit. The hole is drilled to the elevation of the bottom of the hole, and the hole depth is 24m; the prefabricated square pile is hoi...
