Abstract
The invention discloses an integrated double-bag enlarged anchor cable which comprises a positioning head guard and a grouting pipe. A reverse-osmosis hole sealing bag and a reverse-osmosis enlarged bag are respectively fixed to the positions, close to two ends, on the grouting pipe by using a pair of press hoops, a clamping head is installed on the outer sides of the press hoops at two ends of two bag bodies respectively in a tightly-attached mode, symmetric through holes are formed in two sides of each clamping head respectively, a gland is arranged at the position of a grouting hole formed in the head guard, a locking nut is arranged at the center of the gland, guide pipes passing through the bags are respectively fixed in the through holes formed in the clamping heads corresponding to the two bag bodies, an anchor cable from the gland to the rear end of the grouting pipe penetrates into the cavities of the guide pipes, corresponding to the two bag bodies, on two sides respectively, a one-way grouting valve is arranged on the grouting pipe sections in the two bag bodies respectively, and a water-air separating filter valve is arranged in the airtight section between the hole sealing bag and the enlarged bag. The two bag bodies are both made of reverse-osmosis antiseptic cloth.
Description
Technical field:
The present invention relates to fixed building, the two bellows of the integration particularly used in a kind of construction work underpin expands body anchor cable.
Background technology:
The expansion body anchor cable used during existing construction work underpin, all, at four anchor cable ends, a location head protector is installed, anchor cable fixes one by two crimps in anchor cable rear end and expands somatocyst, expansion two crimp outer ends of somatocyst and the anchor pole of head protector rear end are fixed with a dop respectively, penetrate a Grouting Pipe and a draining tracheae with through hole respectively in the dop both sides at crimp two ends.This traditional single capsule expands body anchor cable, in slurry process of setting, because the evaporation of moisture easily causes pore and crackle, reduces the resistance to plucking dynamics of anchoring; In addition because adopt nature grouting mode, not only slow the but also slurry of slip casting not easily enters in the crack of soil layer, affects workmanship.
Summary of the invention:
Body anchor cable is expanded in resistance to plucking great efforts when the object of this invention is to provide a kind of anchoring, the two bellows of integration not easily producing pore and crackle.
Technical scheme of the present invention completes as follows, the two bellows of integration expands body anchor cable, it includes location head protector and a Grouting Pipe, it is characterized in that: in Grouting Pipe, be fixed with a counter-infiltration sealing of hole capsule and a counter-infiltration expansion somatocyst by a pair crimp respectively by two, be adjacent to respectively outside the crimp at two utricule two ends and a dop is installed, a symmetrical through hole is respectively equipped with in each dop both sides, injected hole place in head protector is provided with a gland, a locking nut is provided with at gland center, one is fixed with respectively by the guide pipe in capsule in the dop through hole that two utricules are corresponding, one is penetrated respectively from gland to the anchor cable of Grouting Pipe rear end in the both sides guide pipe cavity that two utricules are corresponding, Grouting Pipe in two utricules is respectively equipped with a unidirectional grout valve, the isolated trap valve of aqueous vapor is provided with in airtight section between sealing of hole capsule and expansion somatocyst.Two utricules all adopt the anticorrosion cloth of counter-infiltration to make.
The present invention, through above-mentioned improvement, can improve anchoring quality greatly, and the resistance to plucking dynamics after adopting two capsule anchoring to not only increase anchoring, adopts the aqueous vapor in aqueous vapor isolated trap valve energy separating slurry, avoids producing pore and crackle.Be specially adapted to highrise building, track traffic, bridge tunel engineering, City Underground Transportation, grade separation hub, port and pier, reservoir high dam, slope project, mine construction, the ground stabilization in the fields such as defence construction.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Detailed description of the invention:
Describe embodiment in detail by reference to the accompanying drawings, it includes location head protector 6 and a Grouting Pipe 1, Grouting Pipe is fixed with a counter-infiltration sealing of hole capsule 4 and a counter-infiltration expansion somatocyst 5 by a pair crimp 3 respectively by two, be adjacent to respectively outside the crimp at two utricule two ends and a dop 2 is installed, a symmetrical through hole is respectively equipped with in each dop both sides, injected hole place in head protector is provided with a gland 8, a locking nut 7 is provided with at gland center, one is fixed with respectively by the guide pipe 12 in capsule in the dop through hole that two utricules are corresponding, one is penetrated respectively from gland to the anchor cable 14 of Grouting Pipe rear end in the both sides guide pipe cavity that two utricules are corresponding, Grouting Pipe in two utricules is respectively equipped with a unidirectional pulp-expelling valve 10, the isolated trap valve 11 of aqueous vapor is provided with in airtight section between sealing of hole capsule and expansion somatocyst.The aqueous vapor in slurry can be facilitated to discharge boring from draining tracheae.Two utricules all adopt the anticorrosion cloth of counter-infiltration to make, and effectively realize the middle water of cement grout and being separated of gas.During use, the present invention is sent into stratum by holing, then in Grouting Pipe, connect grouting pump enforcement operation, in slip casting process, first sealing of hole capsule opens slip casting until slip casting consolidation by one way valve, and orifice sealing is complete; Thereafter open the one way valve expanded in somatocyst and carry out slip casting, after slip casting is completed, the one-way cock of expansion somatocyst outside is opened and is expanded the lasting spilling of band compressed water slurry unnecessary in somatocyst, and the confined space between two utricules and the crack in this region are all filled slurries.Be located at sealing of hole capsule simultaneously and expand aqueous vapor strainer valve between somatocyst by the water in slurry herein and gas separaion, and by outside the gutter tap on sealing of hole capsule, formed and there is no the high strength of pore and crackle, closely knit sealing of hole entity.
