Abstract
A kind of method for pulling out of static pressure pipe pile first removes the surflaes in static pressure pipe pile；Then reinforcing bar is inserted into static pressure pipe pile；Micro-expansion cement mortar or grouting material are injected into static pressure pipe pile again, after intensity reaches requirement, takes shake drawing to go out technique and carries out drawing, whole static pressure pipe pile is extracted；When static pressure pipe pile length is longer, partial cut can will be extracted, then proceed to extract remainder；Static pressure pipe pile fills and leads up the empty hole left after all extracting.This method is simple and effective, transfers to tubular pole convenient and efficient, and success rate is high；And recyclable static pressure pipe pile recycles.
Description
Technical field
It is especially a kind of useless to what is left in the soft layer of city during subway work the present invention relates to subway work
Abandon the method that static pressure pipe pile is extracted.
Background technique
We often use pre-tensioning system technique to make prestressed high-strength coagulation at the industrial pile foundation with civil buildings in house at present
Native tubular pole (i.e. PHC) and prestressed concrete pipe pile (i.e. PC), such tubular pole are referred to as static pressure pipe pile.
During Urban Metro Construction, it is relatively common that shield machine passes through the case where old town encounters engineering pile.Shield machine
Once encountering waste and old pile body, drilling head can be caused to scrap accident, lost very serious.For the generation for avoiding such accident, it is necessary to
The discarded tubular pole for being embedded in underground is handled before construction.
Currently, usually discarded stake is smashed to pieces with Wu Kesi drilling machine to the method that discarded static pressure pipe pile is handled.This
Kind processing method, cannot not only recycle tubular pole, but also in soft stratum, because the reasons such as pile body inclination, removing make part by steel
Muscle or the tubular pole of steel building can not be smashed to pieces, and the subsequent construction of Suporting structure is still influenced.
To discarded tubular pole using the means of filling out are changed, although largely effective, the redistribution of entire stratum load, structure can be caused
Building object internal force need to recalculate, and operating expenses will increase.
Summary of the invention
In view of the above-mentioned problems existing in the prior art, the object of the present invention is to provide it is a kind of it is simple and effective, can quickly pull out
The method of static pressure pipe pile out.
The method for pulling out of static pressure pipe pile provided by the invention is first to remove the surflaes in static pressure pipe pile；Then reinforcing bar is inserted
Enter in static pressure pipe pile；Micro-expansion cement mortar is injected into static pressure pipe pile again or grouting material takes shake after intensity reaches requirement
Drawing goes out technique and carries out drawing, and whole static pressure pipe pile is extracted；When static pressure pipe pile length is longer, partial cut can will be extracted,
It then proceedes to extract remainder；Static pressure pipe pile fills and leads up the empty hole left after all extracting.
The method of the present invention is simple and effective, transfers to static pressure pipe pile convenient and efficient, and success rate is high；And it is sharp again that static pressure pipe pile can be recycled
With.
Specific embodiment
Embodiment
The present embodiment is to extract in certain Urban Metro Construction to static pressure pipe pile is discarded existing for shield machine construction region
Method.
The interior of the discarded static pressure pipe pile of this area is 200mm.
Specifically extracting construction method is：Method is first manually dug out with Luoyang Spade or 30 prospecting drilling machines dig out method and remove static pressure
Surflaes in tubular pole；Then the level Four screw-thread steel with ribbing of diameter 40 is inserted into the inner hole of tubular pole；Microdilatancy is injected into tubular pole again
Cement mortar takes shake drawing to go out technique and carries out drawing, every dial-out 6m or so is used after intensity reaches M40 with hydraulic tube drawing bench
Toothless saw will extract partial cut, then proceed to extract remainder；Static pressure pipe pile fills and leads up the empty hole left after all extracting.
Claims (1)
1. a kind of method for pulling out of static pressure pipe pile, characterized in that first remove the surflaes in static pressure pipe pile；Then reinforcing bar is inserted into quiet
In pressure pipe stake；Micro-expansion cement mortar is injected into static pressure pipe pile again or grouting material takes shake drawing after intensity reaches requirement
Technique carries out drawing out, and whole static pressure pipe pile is extracted；When static pressure pipe pile length is longer, partial cut can will be extracted, then
Continue to extract remainder；Static pressure pipe pile fills and leads up the empty hole left after all extracting.
