Description
Technical field
A kind of concrete grouting device is the utility model is related to, more particularly to a kind of blocking concrete diaphragm wall leakage point
Expanding fluid filling tube.
Background technology
In architectural engineering, diaphram wall top plate and ground wall connecting portion, two width wall connecting portion, locking notch pipe pull off
Position, pre-buried connector position and concrete rejected region happen occasionally percolating water phenomenon.This leakage for diaphragm wall must enter
Row closure.Conventional plugging processes are to carry out chemical grouting using insertion Grouting Pipe after water drilling punching.The Grouting Pipe used at present is equal
For circular tube structure, for this circular Grouting Pipe due to the Aperture deviation of water drilling hole, there is radial gap in drilling with Grouting Pipe, this
On the one hand individual gap causes grouting pressure during slip casting to be revealed, pressure does not reach requirement, and slip casting effect is poor, to improve grouting quality,
Grouting pressure is often increased, again diaphragm wall can be made new crackle occur in the case where increasing grouting pressure, cause the two of diaphragm wall
Secondary injury；On the other hand, because this gap reason can cause chemical grout to be flowed out along pipe outer wall, and slip casting pressure is being increased
In the case of power, this leakage is then more serious, seriously pollutes concrete structure, damaged outward appearance, reduces construction quality.Therefore,
It is the key for realizing high quality closure diaphragm wall leakage point to eliminate the radial gap between Grouting Pipe and drilling.
Utility model content
The purpose of this utility model is for out a kind of easy to operate, can eliminate the seam between Grouting Pipe and slip casting duct
Gap, make both be brought into close contact to form confined space, ensure that chemical grout grouting pressure does not leak, avoid increasing grouting pressure to even
Continuous wall causes secondary injury, can improve the expanding fluid filling tube of grouting for water plugging construction quality and outward appearance U.S..
What the purpose of this utility model was that by.The utility model expanding fluid filling tube is responsible for including slip casting, this reality
It is characterised by with novel expansion Grouting Pipe：The slip casting supervisor is overall by thread segment, minor diameter light bar segment and enlarged diameter section
Form, turn nut be threadedly coupled on the thread segment, be socketed successively from left to right in the minor diameter light bar segment squeezing bushing,
Big expansion sleeve, transmission sleeve pipe and small expansion sleeve, the turn nut are fitted and connected with squeezing bushing, the squeezing bushing,
Big expansion sleeve, transmission sleeve pipe and small expansion sleeve are bonded to each other connection, and the small expansion sleeve is landed in the prominent of enlarged diameter section
Rise on end face.
The utility model expanding fluid filling tube, wherein the squeezing bushing, big expansion sleeve, transmission sleeve pipe and small expansion sleeve
The internal diameter of pipe and the external diameter of minor diameter light bar segment into there is a gap matching pair, the squeezing bushing, big expansion sleeve, transmission sleeve pipe and
The external diameter of small expansion sleeve and the external diameter of enlarged diameter section are of substantially equal, and the external diameter of the turn nut is less than the outer of enlarged diameter section
Footpath, for the turn nut under tightening state, big expansion sleeve and small expansion sleeve are in extruded swelling state.
The utility model expanding fluid filling tube, wherein the big expansion sleeve and small expansion sleeve are in the expanded state outside it
Footpath is more than squeezing bushing and is driven the external diameter of sleeve pipe.
The utility model expanding fluid filling tube, wherein the big expansion sleeve and small expansion sleeve are made up of rubber tube, institute
State squeezing bushing and transmission sleeve pipe is made up of rigid material.
The utility model expanding fluid filling tube difference from prior art is that the utility model expanding fluid filling tube is
Squeezing bushing, big expansion sleeve, transmission sleeve pipe and small expansion sleeve are socketed successively in slip casting supervisor's outside wall surface to form.Slip casting
Supervisor is monolithically fabricated by thread segment, minor diameter light bar segment and enlarged diameter section.The turn nut on slip casting supervisor's left end screw thread is screwed,
By squeezing bushing and transmission sleeve pipe extrudes big expansion sleeve and small expansion sleeve is allowed to expand, and reaches expanding fluid filling tube and water
The purpose that boring aperture is brought into close contact.It can be eliminated between Grouting Pipe and slip casting duct using expanding fluid filling tube of the present utility model
Gap, make both expanding fluid filling tube and slip casting duct be brought into close contact to form confined space, ensure chemical grout grouting pressure
Do not leak, both effectively prevent and increased grouting pressure secondary injury to caused by diaphragm wall, drastically increased grouting for water plugging again
The construction of operation and presentation quality.Expanding fluid filling tube of the present utility model is rational in infrastructure, easy to operate, and it is that a kind of completion is oozed
The ideal tools for the treatment of water leakage work.
Expanding fluid filling tube of the present utility model is described further below in conjunction with the accompanying drawings.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model expanding fluid filling tube.
Fig. 2 is that structural representation is responsible in the slip casting of the utility model expanding fluid filling tube.
