Description
Technical field
The present invention relates to a kind of building pile foundation construction method, be specifically related to a kind of construction method of high viscosity soil soil layer long spire pile high-pressure gas-vapor mix pore-forming.
Background technology
Long auger stake is in the king-sized soil layer of viscosity (as rich clay, argillaceous rocks that rate of decay is high), the soil body that drill bit gets out, very easily stick between drilling rod and the flight of drill bit, the soil body cannot be up along flight under the rotary thrust effect of drilling rod, and the soil body and drilling tool can form longer, earth pillar closely, be blocked on drill bit, cause entering to bore, cause the construction method of long auger can not be applicable to rich clay and the high argillaceous rocks geology of rate of decay.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of speed of application is fast, the construction method of engineering geology compliance long spire pile high-pressure gas-vapor mix pore-forming widely.
For solving above technical problem, technical scheme of the present invention is: a kind of construction method of high viscosity soil soil layer long spire pile high-pressure gas-vapor mix pore-forming, is characterized in that comprising the steps:
The first step: install multichannel central shunt under the unit head of long spire stake machine, at high pressure water transport pipe and the appendix of the outside mounting strap injector head of long screw drill rod;
Second step: when bit drills is to viscous soil horizon, utilizes high pressure water-injection pump to inject water under high pressure in high pressure water transport pipe, and the current of high-pressure injection cut the cohesive soil between flight, makes cohesive soil form chunky shape;
3rd step: utilize air compressor to be pressed into air in appendix;
4th step: the mixture forming water, gas and soil at the bottom of stake, goes upward to stake holes mouth along flight under the rotary thrust effect of drilling rod.
The injector head of described high pressure water transport pipe is symmetricly set on the outer wall of the central tube between two flights on drill bit top.
The gas outlet of described appendix is symmetricly set on the outer wall of the central tube between two flights of drill bit bottom.
5 ~ 10 times that the pressure of described press-in air is 0.6 ~ 1.2MPa, the discharge capacity of air is the amount of being unearthed.
The pressure of described water under high pressure is 10 ~ 20MPa, water under high pressure discharge capacity is 0.15 ~ 0.2m per minute
3.
The present invention by arranging water-supply-pipe and appendix on the central tube of long screw drill rod and drill bit, water under high pressure is utilized to cut the cohesive soil between flight, cohesive soil is made to form chunky shape, reduce the viscosity between soil block and flight and adsorptivity, play lubrication and airtight effect, by pressure-air, powerful thrust is formed to soil block simultaneously, force the soil body got out constantly up along flight, to reduce in boring procedure hole wall to the collateral resistance of drilling rod simultaneously, solve a difficult problem for unit head moment of torsion deficiency when piercing deep hole, drill bit is easily pierced in darker rock-soil layer.This construction method is easy and simple to handle, rock-soil layer applied range, pile-forming speed fast, significantly can provide the efficiency of construction of long spire stake machine, solves the difficult problem always perplexing pile foundation industry for a long time, therefore has wide market prospects.
