Abstract
A construction method of casting pipe pile plucking with resistance to plucking and pressing, The invention relates to a construction method of pipe pile. The purpose of the invention is: solving the insufficient problems of resistance to plucking and pressing happened in the buildings which are built under complex geological conditions or under higher groundwater level geological strata and the problems are generated by bottom board percolating water due to buildings bottom board plucking resistance is insufficient, declination due to excessive eccentricity when design buildings and when design the resistance to plucking of new buildings. The invention drills hole downward on the buildings basic layer according the design height mark and bore diameter of pipe pile, lifts downward steel pipes or plastic pipes with slip casting hole after the drilled hole is completed, lifts downward reinforcement bar or reinforcement cage in the hole out the steel pipes or plastic pipes, lifts downward sands and broken stone between the outer wall of the steel pipes or plastic pipes and the hole wall. The invention has extremely distinctive action in buildings plucking-resistance and reinforcement, buildings declination correction and the foundation reinforcement project of house floors addition and reconstruction. The pile type in the invention is suitable for various geological strata, it can be used for the plucking-resistance, reinforcement and foundation reinforcement of prior buildings and the resistance-plucking pile construction of new buildings.
Description
Technical field
The present invention relates to a kind of job practices of pile tube.
Background technology
The building of building on geological conditions complexity or the higher stratum of groundwater table tends to produce following point: the one, and the design of building base plate anti-floating is not enough, makes base plate produce the crack infiltration; The 2nd, whole building designs eccentric excessive generation and tilts; The 3rd, uplift pile uplift resistance deficiency when the new building thing carries out the anti-floating design.The method that prevents at present or administer all can not thoroughly address the above problem.
Summary of the invention
The objective of the invention is the building built on geological conditions complexity or the higher stratum of groundwater table for solving, the foot plate infiltration of building base plate anti-floating power, building design eccentric excessive generation inclination, the not enough problem of uplift pile uplift resistance when the new building thing carries out the anti-floating design, and a kind of job practices of pulling-resistant and pressure-resistant slip casting pipe pile is provided.Method of the present invention realizes by following steps: one, hole downwards on the basal layer of building according to the design elevation and the aperture of stake; Two, be lowered to the steel pipe or the plastic pipe of band injected hole behind the pore-forming in the hole, the position of steel pipe or plastic pipe is placed in the middle in the hole; Three, in the hole in the steel pipe or the plastic pipe outside, be lowered to reinforcing bar or reinforcing cage; Four, in the outer wall of steel pipe or plastic pipe and the space between the hole wall, be lowered to sand or rubble; Five, in steel pipe or plastic pipe, be lowered to the Grouting Pipe of band grouting stop-valve; Six, start grouting pump and begin slip casting in the stake hole; Seven, steel pipe or plastic pipe carry out effectively (welding) and are connected and seal a waterproofing work respectively with between the basal layer of reinforcing bar or reinforcing cage and building behind the pile.The present invention has effect extremely significantly in the ground base enforcement engineering of the anti-floating reinforcing of building, building inclination rectification, adding building layer transformation.Stake type of the present invention is applicable to various stratum, according to the groundwater table height, can adopt different pore-forming technique pore-formings, pile.Can carry out stake footpath according to different uplift resistances, stake is long and the adjustment of reinforcing cage ,-also can carry out slip casing by pressure repeatedly simultaneously at the different position of pile body, the stake footpath is enlarged, form special-shaped enlarged footing, be used to improve resistance to plucking, compressive resistance.The present invention can be used for anti-floating reinforcing, ground base enforcement and the new building thing uplift pile construction of existing building.
