Abstract
The utility model disclose a leakage blocking and grouting device between deep foundation pit fender posts and solves the problem that during treatment of internal leakage of a deep foundation pit in the prior art, the grouting and blocking operation in the foundation pit is high in danger coefficient. The leakage blocking and grouting device comprises the deep foundation pit (1), the fender posts (2) are disposed on the periphery of the deep foundation pit (1), a water leakage point (4) exists between two adjacent fender posts (2), a blocking steel plate (3) is disposed on the inner sides of the two adjacent fender posts (2), a grouting and leakage blocking hole (5) is formed in the outer side of the two adjacent fender posts (2), a grouting shock tube (6) is disposed in the grouting and leakage blocking hole (5), and a grouting device (7) is connected to the top end of the grouting shock tube (6). By the leakage blocking and grouting device, operation risk of water leakage point blocking is lowered greatly.
Description
Technical field
The utility model relates to a kind of leak stopping grouting device, particularly between a kind of deep foundation pit fender post seepage or pile body when discontinuous cause the leak stopping grouting device of seepage.
Background technology
In the civil engineering foundation pit construction of subway station, inaccurate due to the geological mapping to groundwater condition, discontinuous sealing of supporting pile structure design, or in work progress, go along with sb. to guard him interlocking pile and occur jag, all can there is seepage groundwater condition between fender post.When water amount of seepage hour, be generally the underground water of taking in the bright row's of foundation ditch mode drainage foundation ditch, in the time that water amount of seepage is larger, and not in the situation that of foundation ditch periphery dewatering well, just need to take urgent measure, Leakage of Foundation Pit water is processed.Prior art is from foundation ditch inside to breakthrough position horizontal drilling, then carries out slip casting shutoff.But when excavation of foundation pit is crossed when dark, support system in foundation ditch is relatively intensive, causing carrying out in foundation ditch inside the equipment and materials that Seepage water uses cannot transport in foundation ditch, in addition, because the seepage of foundation pit enclosure structure can directly cause the distortion of space enclosing structure, and even coming off and the unstability of space enclosing structure of support system mended and oozed operation and have very large security risk in foundation ditch, and security incident easily occurs.
Summary of the invention
The utility model provides the grouting device of the leak stopping between a kind of deep foundation pit fender post, solved prior art in the time processing deep foundation ditch internal leak existing in foundation ditch the large technical problem of slip casting shutoff operation danger coefficient.
The utility model is to solve by the following technical programs above technical problem:
Leak stopping grouting device between a kind of deep foundation pit fender post, comprise deep foundation ditch 1, be provided with fender post 2 at the periphery of deep foundation ditch 1, between two adjacent fender posts 2, have seepage water spot 4, on the medial surface of the two adjacent fender posts 2 that have seepage water spot 4, be provided with shutoff steel plate 3, arranged outside at the two adjacent fender posts 2 that have seepage water spot 4 has grouting for water plugging hole 5, is provided with grouting tube 6 in grouting for water plugging hole 5, and the top of grouting tube 6 is connected with grouting device 7.
Shutoff steel plate 3 is to be fixed on the medial surface of the two adjacent fender posts 2 that have seepage water spot 4 by expansion bolt 8, and described grouting device 7 is arranged on the ground of foundation ditch 1 outside.
The utility model is that grouting for water plugging hole is arranged on the ground in foundation ditch outside, has solved the problem of percolating water between bracing of foundation pit stake on ground to breakthrough position injection biliquid slurry, and whole mending-leakage process safety is convenient; Also facilitate the collection to earth's surface tour and monitored data simultaneously, greatly reduce the operating risk of seepage water spot shutoff processing.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view of the utility model in A-A direction in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is elaborated:
Leak stopping grouting device between a kind of deep foundation pit fender post, comprise deep foundation ditch 1, be provided with fender post 2 at the periphery of deep foundation ditch 1, between two adjacent fender posts 2, have seepage water spot 4, on the medial surface of the two adjacent fender posts 2 that have seepage water spot 4, be provided with shutoff steel plate 3, arranged outside at the two adjacent fender posts 2 that have seepage water spot 4 has grouting for water plugging hole 5, is provided with grouting tube 6 in grouting for water plugging hole 5, and the top of grouting tube 6 is connected with grouting device 7.
Shutoff steel plate 3 is to be fixed on the medial surface of the two adjacent fender posts 2 that have seepage water spot 4 by expansion bolt 8, and described grouting device 7 is arranged on the ground of foundation ditch 1 outside.
Specific construction step of the present utility model is as follows: in the time there is larger seepage water spot 4 between two fender posts 2 of deep foundation ditch 1, on the medial surface of timely two fender posts 2 at seepage water spot 4 places, shutoff steel plate 3 is set, shutoff steel plate can adopt the steel plate of 3-5 millimeters thick, determines the size of shutoff steel plate 3 according to the size of seepage water spot 4.For convenience of operation, shutoff steel plate 3 also can adopt fritter steel plate splicing to form, shutoff steel plate 3 is fixed on by expansion bolt 8 on the medial surface of two fender posts 2, meanwhile, hole is drawn on top at the seepage water spot 4 of ground enclosing structure outside, is to arrive expection plugging effect, draws hole depth outline and be deeper than the position of seepage water spot, after pore-forming, in hole, lay in time grouting tube 6, the top of grouting tube 6 and grouting device 7 connect.After equipment connection has been debugged, first inject single liquid slurry, when flow out after single liquid slurry seepage water spot position between the inner stake of foundation ditch, start injection biliquid slurry.Biliquid slurry is set in the outside of shutoff steel plate 3 by current, by continuous injection biliquid slurry, form gradually transfer barrier, thereby reach the effect of sealing in the behind of shutoff steel plate 3.
