Drawings
FIG. 1 is a schematic overall structure of the present application;
fig. 2 is a structural schematic diagram of the installation relationship between the grouting nozzle and the hose.
In the above drawings: 1. a sealing layer; 2. a grouting nozzle; 21. a grouting pipe; 22. positioning a plate; 3. grouting layer; 4. a waterproof layer; 5. a wall body; 51. filling the groove; 6. a hose.
Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.
A leaking stoppage structure for a crack of an outer wall of a basement of a deep foundation pit refers to fig. 1 and comprises a sealing layer 1 fixed at an opening of a filling groove 51 and a grouting nozzle 2 arranged on the sealing layer 1, wherein the sealing layer 1 and the filling groove 51 form a closed cavity so as to bear high-pressure slurry.
The sealing layer 1 is made of LB-8 quick-hardening cement purchased in the market, so that the forming speed of the sealing layer 1 is higher, and the construction period is shortened. The grouting nozzle 2 comprises a grouting pipe 21 and a positioning plate 22 arranged on the grouting pipe 21, the positioning plate 22 is positioned on one side of the grouting pipe 21 close to the bottom of the filling groove 51, when the sealing layer 1 is manufactured by sealing and plastering, the grouting nozzle 2 is installed stably, and the grouting nozzle 2 is formed on the sealing layer 1.
The sealing layer 1 and the filling groove 51 are filled with high-pressure slurry to form a grouting layer 3, the grouting layer 3 is LB-7 neoprene latex polymer cement slurry, the LB-7 neoprene latex polymer cement slurry is prepared by uniformly mixing LB-7 neoprene latex cement slurry waterproof agents purchased from the market and cement slurry in a certain proportion, the cement slurry has the repairing effect and the waterproof property, the possibility that water on the outer side of the wall body permeates into the wall body is reduced, and the wall body can be better protected.
The waterproof layer 4 is laid on one side, far away from the grouting layer 3, of the sealing layer 1, the waterproof layer 4 is made of LB-21 epoxy emulsion daub purchased through the market, the waterproof material has better waterproofness, and the cost performance of the plugging structure is higher on the premise that waterproof conditions are guaranteed.
The application relates to a construction principle of a leaking stoppage structure for a deep foundation pit basement outer wall crack, which comprises the following steps: referring to fig. 2, a filling groove 51 is formed in the inner joint of the wall 5 along the length direction of the crack, and the filling groove 51 has a V-shaped cross section to clean concrete residues in the filling groove.
Laying the hose 6 at the bottom of the filling groove 51 along the length direction of the filling groove 51, installing a plurality of grouting nozzles 2 in the filling groove 51 at intervals, and sealing and smearing by using quick-setting cement to form a closed layer 1; when the sealing layer 1 is formed, the hose 6 is drawn out, the sealing layer 1 and the filling groove 51 form a closed cavity, and the end part of the grouting pipe 21 close to the positioning plate 22 is abutted against the hose 6 when the grouting nozzle 2 is installed, so that the grouting nozzle 2 is ensured to be communicated with the closed cavity.
The grouting nozzle 2 is communicated with a high-pressure grouting machine, high-pressure LB-7 neoprene latex polymer cement slurry is injected into the closed cavity to form a grouting layer 3, and due to the fact that the capillary cracks of the wall body are communicated with the filling groove 51, fillers enter the capillary cracks under high pressure, and the reinforcing effect of the crack positions of the wall body is good.
And after the sealed cavity is filled with the grout, the high-pressure grouting machine is disconnected, and the grouting nozzle 2 is bent and sealed, so that the possibility of the backflow of the grout in the cavity is reduced.
The waterproof layer 4 is coated on the outer side of the sealing layer 1, so that the sealing structure has higher waterproof performance.
When the sealing layer 1 is manufactured, a certain distance can be reserved between the sealing layer 1 and the notch of the filling groove 51, so that the filling plane height can be adjusted for leveling during secondary filling.
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
