Abstract
The invention discloses a seepage-proofing joint device of a diaphragm wall, which is characterized by comprising a vertical center steel pipe and four wing steel plates, wherein the four wing steel plates are vertically welded on the outer wall of the center steel pipe to form a cross shape, the center steel pipe between two adjacent wing steel plates is provided with injection holes; and the injection holes are sealed by using a high-pressure air bag when concrete is poured, and the injection holes are used for injecting slurry after the concrete is poured so that the purpose of preventing seepage is achieved. The invention has the main advantages of simple structure, no need of special construction tools, and good seepage proofing effect.
Description
Technical field
The invention belongs to field of civil engineering, particularly a kind of anti-seepage joint of underground continuous walls device.
Background technology
Diaphragm wall is the underground structure that is coupled together by continuous wall connector by a plurality of unit body of wall, the general method of construction piecemeal that adopts, that is: carry out the construction of a segment unit wall earlier, and put into continuous wall connector, and carry out the construction of next adjacent segment unit wall then, connect by joint between two sections walls, therefore, the concrete that two sections different times are built easily produces the slit in the joint, become wall after, artesian water is just by this position infiltration.
Common i iron and four-bladed vane joint is not really desirable aspect anti-seepage effect at present, infiltration problem often occurs.
Summary of the invention
The object of the present invention is to provide a kind of anti-seepage joint of underground continuous walls device, solve the long artesian water infiltration problem of seeing in the construction of diaphragm wall.
Purpose of the present invention is achieved through the following technical solutions:
A kind of anti-seepage joint of underground continuous walls device, constitute by a vertical center steel pipe and four wing steel plates, described four wing steel plates vertically are welded on the outer wall of steel pipe of center, across, be equipped with injected hole on the center steel pipe between described adjacent two wing steel plates, this injected hole is sealed with high-pressure gasbag when concreting, utilizes injected hole slip casting after the concreting again, to reach the antiseepage purpose.
Preferably, described wing steel plate is a rectangular slab, its long limit and the welding of center steel pipe.
Preferably, the long limit of described wing steel plate equates with pipe range.
Preferably, described four wing steel plates radially extends all center line through the center steel pipe.
Preferably, described wing steel plate is divided into long and short wing steel plate, and what the minor face of wing steel plate was long is long wing steel plate, and short is the short limb steel plate, and it is a pair of that described long and short wing steel plate respectively has, and be provided with at interval.
Preferably, described injected hole is evenly distributed on the steel pipe of whole piece center.
The present invention compared with prior art has following advantage:
The present invention adopts these piecing devices can solve the body of wall joint to connect untight problem, makes that wall is intersegmental to be linked to be unified integral body, to reach good impermeable effect.

The specific embodiment
Embodiment 1
A kind of anti-seepage joint of underground continuous walls device is made of a vertical center steel pipe 10 and four wing steel plates 20, and four wing steel plates 20 vertically are welded on center steel pipe 10 outer walls across.Described wing steel plate 20 is a rectangular slab, its long limit and 10 welding of center steel pipe, and should equate with pipe range on long limit.Four wing steel plates 20 radially extend all center line through center steel pipe 10.Wing steel plate 20 comprises a pair of long wing steel plate 21 and a pair of short limb steel plate 22, and what the minor face of wing steel plate was long is long wing steel plate 21, and what minor face was short is short limb steel plate 22, and long and short wing steel plate 21,22 is provided with at interval.Be equipped with injected hole 11 on the center steel pipe 10 between adjacent two wing steel plates 20, injected hole is evenly distributed on whole piece center steel pipe 10.
The form of construction work of above-mentioned anti-seepage joint of underground continuous walls device is as follows:
1. carry out the construction of a segment unit wall earlier, put into above-mentioned piecing devices when putting into reinforcing cage, and put into high-pressure gasbag in the steel pipe of center, gas-flow closure is lived injected hole, builds concrete and makes a long wing steel plate of piecing devices be fixed in this segment unit within the walls;
2. carry out the construction of next adjacent segment unit wall, the pressure that keeps high-pressure gasbag during this time, after the concrete for the treatment of body of wall is built, remove air bag, slip casting in the steel pipe upper port of center, slurry enters in the wall seam by injected hole, makes the gap sealing of two sections diaphragm wall junctions, reaches the purpose that prevents the artesian water infiltration.
Claims (6)
1. anti-seepage joint of underground continuous walls device, it is characterized in that be made of a vertical center steel pipe and four wing steel plates, described four wing steel plates vertically are welded on the outer wall of steel pipe of center, across is equipped with injected hole on the center steel pipe between described adjacent two wing steel plates.
2. device according to claim 1 is characterized in that, described wing steel plate is a rectangular slab, its long limit and the welding of center steel pipe.
3. device according to claim 2 is characterized in that, the long limit of described wing steel plate equates with pipe range.
4. device according to claim 3 is characterized in that, described four wing steel plates radially extend all center line through the center steel pipe.
5. according to claim 2 or 3 or 4 described devices, it is characterized in that described wing steel plate is divided into long and short wing steel plate, what the minor face of wing steel plate was long is long wing steel plate, and short is the short limb steel plate, and it is a pair of that described long and short wing steel plate respectively has, and be provided with at interval.
6. device according to claim 5 is characterized in that, described injected hole is evenly distributed on the steel pipe of whole piece center.
