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

[0001] The invention relates to a construction method of pipe piles. Background technique

[0002] Buildings built on strata with complex geological conditions or high groundwater levels often have the following problems: first, the anti-floating design of the building floor is insufficient, causing cracks and water seepage in the floor; second, the design of the entire building is too eccentric to cause inclination The third is that the uplift resistance of the uplift piles is insufficient when the new buildings are designed for anti-floating. None of the current prevention or treatment methods can completely solve the above problems. Contents of the invention

[0003] The purpose of the present invention is to solve the problems of buildings built in strata with complex geological conditions or high groundwater levels, when the floor of the building has insufficient buoyancy resistance to water seepage of the floor, the design eccentricity of the buildin...
