Abstract
The present invention relates to concrete filling pile, more particularly to concrete filling pile casting method.A kind of Karst Fissures region concrete filling pile pours anti-leaking method, and it includes：Step one, formation area construction bored concrete pile spots localization drilling, borehole cleaning；Step 2, makes filling pile cage of reinforcement, welding righting positioner；Righting positioner is the semicircle ring being overlapped between adjacent two sections of steel reinforcement cages；Step 3, welds bored concrete pile back cover plug steel plate；Step 4, outsourcing elasticity geotextiles, can be open at righting positioner, elastic geotextiles is located in location centralizing device；Step 5, geotextiles are fastenedly connected with back cover plug；Step 6, steel reinforcement cage install tremie placing concrete after putting well.The present invention prevents Karst Fissures region drill-pouring pile concrete to be lost in.
Description
Technical field
The present invention relates to concrete filling pile, more particularly to concrete filling pile casting method.
Background technology
When cast-in-situ bored pile is located at formation area construction, because there is rock crack development and karst hole etc. in many places formation area.After pouring pile hole is put into steel reinforcement cage, because the presence in karst hole and crack can be such that the concrete for pouring into is lost in a large number, cause greatly to waste and hidden danger of quality.
The content of the invention
Present invention seek to address that the drawbacks described above of prior art, there is provided a kind of Karst Fissures region concrete filling pile pours anti-leaking method.The present invention prevents Karst Fissures region drill-pouring pile concrete to be lost in.
What the present invention was realized in：A kind of Karst Fissures region concrete filling pile pours anti-leaking method, and it includes：
Step one, formation area construction bored concrete pile spots localization drilling, borehole cleaning；
Step 2, makes filling pile cage of reinforcement, welding righting positioner；Righting positioner is the semicircle ring being overlapped between adjacent two sections of steel reinforcement cages；
Step 3, welds bored concrete pile back cover plug steel plate；
Step 4, outsourcing elasticity geotextiles, can be open at righting positioner, elastic geotextiles is located in location centralizing device；
Step 5, geotextiles are fastenedly connected with back cover plug；
Step 6, steel reinforcement cage install tremie placing concrete after putting well.
Concrete pressure effect after the present invention is poured expands outwardly can elastic geotextiles, be clipped between rock stratum and cast-in-place pile concrete, be brought into close contact therewith, close karst hole and crack, prevent the concrete for pouring into be lost in a large number；Play a part of to isolate karst hole and crack, can guarantee that concrete pouring pile integrity and construction quality again.
Specific embodiment
When making steel reinforcement cage after pore-forming, in steel reinforcement cage bottom, the back cover plug less than pouring pile hole aperture is set, location centralizing device is symmetrically welded in cage bar on the outside of steel reinforcement cage, then outsourcing elasticity geotextiles, geotextiles bottom is fastenedly connected with back cover plug, then steel reinforcement cage is put in priming concrete pile hole, casting concrete, concrete pressure effect after pouring expands outwardly can elastic geotextiles, it is clipped between rock stratum and cast-in-place pile concrete, it is brought into close contact therewith, play a part of to isolate karst hole and crack, concrete pouring pile integrity and construction quality are can guarantee that again.
