Reinforced and plain concrete pile matched occlusive pile construction method

Abstract

The invention relates to the technical field of occlusive pile construction, and discloses a reinforced and plain concrete pile matched occlusive pile construction method. A long spiral drilling machine and a rotary drilling bucket are included. The construction method comprises the following steps: (1) drilling through the long spiral drilling machine, to form a plain concrete hole; (2) lifting the drill while pouring concrete, to form a plain concrete pile; (3) repeating the step (1) and the step (2) to form a plurality of plain concrete piles which are arranged at intervals; (4) drilling through a rotary excavating drilling bucket, and performing hard cutting on adjacent plain concrete piles and soil bodies, to form a reinforced concrete hole; (5) putting a reinforcement cage down to the reinforced concrete hole; (6) pouring concrete into the reinforced concrete hole, to form a reinforced concrete piles; and (7) repeating the steps (4)-(7), and arranging the reinforced concrete piles and the plain concrete piles in a one-to-one corresponding occlusion manner. The sediment amount at the bottom of the plain concrete hole is reduced, collapse of the wall of the plain concrete holeand falling of orifice soil are avoided, the pile body quality is improved, repeated drill bit replacement is not needed, and the construction efficiency is improved; and under the cooperation of thereinforced concrete piles and the plain concrete piles, the waterproof effect of the support structure formed by construction is enhanced.

Description

technical field [0001] The patent of the present invention relates to the technical field of the construction method of occlusal piles, in particular, to the construction method of occlusal piles with meat and vegetables. Background technique [0002] The occlusal pile is to place a reinforced cage pile between adjacent plain concrete piles, so that part of the circumference between the plain concrete pile and the reinforced cage pile is embedded, forming a foundation pit enclosure with good anti-seepage effect and an overall continuous soil and water stop. structure type. [0003] At present, conventional occlusal piles mostly adopt three methods: hard occlusal of rotary pile machine, full casing drilling of pipe rubbing pile machine, and full casing full rotary drilling. [0004] The hard bite construction of the rotary excavation pile machine adopts the rotary drilling rig and the mud wall to form the hole. When the hole is in bad ground, it needs to be lowered into the ...
