Abstract
The utility model discloses a seepage-proof structure for an underground continuous wall, which comprises an underground continuous wall and linings. Permeable material layers are filled in the linings arranged at the positions of gaps of groove sections of the underground continuous wall, a water conduit pipe is arranged outside each permeable material layer, a venting pipe communicated with external environment is connected with the upper end of the water conduit pipe, and a converging pipe communicated with a drainage ditch is connected with the lower end of the water conduit pipe. The seepage-proof structure for the underground continuous wall is simple and easy in construction, can replace a mixing pile and a spraying pile which are arranged behind the wall in areas with low permeability, and can prevent seepage from occurring, materials are convenient to acquire, and post processing is not required. The seepage-proof structure for the underground continuous wall further has the advantages of saving building cost and being quick in construction speed, attractive, practical, and safety in use.
Description
Technical field
The utility model relates to the antiseepage of diaphragm wall to be handled, and refers to a kind of diaphragm wall leakage preventing structure particularly.
Background technology
Diaphragm wall is to utilize various trench machines, retaining wall effect by means of mud, dig to underground drilling have certain thickness, the groove section of length and the degree of depth and in the groove section, put into the good reinforcing cage of processing and fabricating, penetration concrete builds up one section reinforced concrete wall section then, couples together one by one to form the continuous underground wall body that has antiseepage, retaining soil and weight-bearing function together.
Because diaphragm wall can be constructed under various complex conditions,, construction period weak point strong to ground compliance, the advantage that construction costs is low is outstanding, thereby the decompression discharge structure pattern of making the dock chamber wall with underground diaphragm wall is widely used in dry dock.But diaphragm wall is in the process of place grooving segmentation pouring construction, can form a lot of structural joints, and localized seepage easily takes place at the place at groove section parting.Therefore, the antiseepage of diaphragm wall is handled particularly crucial.Usually adopt processing such as agitation pile, rotary churning pile in the outside of diaphragm wall, structural joint rubber fastening band and copper seal.But these scheme construction periods are long, and in fact the cost height can not prevent fully that seepage from taking place, and often will make post-processed.And so processing had both influenced outward appearance, and long-term seepage easily causes the fine grained soil behind the diaphragm wall to run off again, causes security incident to take place.
Summary of the invention
The purpose of this utility model will overcome the deficiencies in the prior art exactly, and a kind of anti-diaphragm wall leakage preventing structure of combination that draws is provided.
For achieving the above object, the diaphragm wall leakage preventing structure that the utility model is designed, comprise diaphragm wall and lining cutting, be filled with the seepy material layer in the lining cutting at the groove section parting place of described diaphragm wall, described seepy material layer is outside equipped with aqueduct, the upper end of described aqueduct is connected with and the extraneous permeability cell that communicates, and the lower end of described aqueduct is connected with the collecting pipe that communicates with the gutter.Permeability cell can prevent that water that groove section parting oozes out from down confluxing and produce vacuum on top in the process, cause water not discharge smoothly after flowing to aqueduct.Aqueduct can be with the organized collecting pipe that is directed to of infiltration behind the wall.The infiltration that collecting pipe can compile aqueduct is discharged into the gutter of dock chamber.The effect of dank material layer is to guarantee that infiltration can flow out smoothly, stop wall simultaneously after fine grained soil run off, guarantee structural safety.
Preferably, also be provided with many stiffeners in the described lining cutting.Like this, can strengthen the fastness of diaphragm wall leakage preventing structure.
The beneficial effects of the utility model are: the utility model is drawn materials conveniently, construction is simple, after permeability is not the too strong alternative wall in place agitation pile, execute anti-permeation method such as spray stake, preventing the seepage generation from not needing to do post-processed.The utility model not only guarantees to seep water and can flow out smoothly, and fine grained soil runs off after stoping wall, guarantees the safety of structure.The utlity model has that speed of application is fast, cost is economized, advantage both artistic and practical, safe in utilization.
Description of drawings
Fig. 1 is a kind of side-looking structural representation of diaphragm wall leakage preventing structure.
Fig. 2 is the A-A sectional structure schematic diagram among Fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Diaphragm wall leakage preventing structure shown in the figure comprises diaphragm wall 7 and lining cutting 6, is filled with seepy material layer 4 in the lining cutting 6 at groove section parting 10 places of diaphragm wall 7, and seepy material layer 4 is outside equipped with aqueduct 2.The upper end of aqueduct 2 is connected with and the extraneous permeability cell 1 that communicates, and the lower end of aqueduct 2 is connected with the collecting pipe 3 that communicates with gutter 9.Also be provided with many stiffeners 8 in the lining cutting 6.
Operating principle of the present utility model is as follows: aforesaid diaphragm wall leakage preventing structure is installed below dock chamber empty van 5.The seepy material layer 4 of the water that groove section parting 10 places of diaphragm wall 7 are oozed out through filling in the lining cutting 6 flows out infiltration smoothly, and down be directed to collecting pipe 3 behind aqueduct 2, and the infiltration that collecting pipe 3 compiles aqueduct 2 is discharged into the gutter 9 of dock chamber.The utility model not only guarantees to seep water and can flow out smoothly, and fine grained soil runs off after stoping wall, guarantees the safety of structure.
