The invention relates to a construction process of floral tube dry filling piles with obvious
engineering effect, low economic cost, high technical content and high
resource utilization by improving the inherent characteristics of
cement, soil strata, materials and the like. The process comprises the following steps of: (1) pore-forming process: 1, using dry pore-forming process for pore-forming piles above underground
water level; 2, positioning a pore opening
machine and a
drill for pore-forming piles below underground
water level; drilling in at low
stroke and high rotary speed with
clean water; reaching a drilling-in depth; lifting to a pore opening at unified
stroke and high rotary speed with
clean water; drilling into a pore bottom at unified
stroke and high rotary speed with
clean water; rotating at high speed and filling with
cement mortar; and lifting to the pore opening at high rotary speed and low stroke after
cement mortar returns to the pore opening; moving the
drill; (2) the process of installation and
pile molding by filling: adopting the following steps for installing
pile pores and filling dry cement above or below
water level: installing floral tubes; correcting the pore position of the floral tubes; filling the dry cement; and filling the dry cement to an elevation required by the design.
