Technical Field

[0001] The utility model relates to the technical field of equipment for tunnel engineering construction, in particular to a water plugging and grouting device for tunnel engineering. Background Art

[0002] In the operation of tunnel engineering construction, water plugging and grouting work is essential. Grouting for water plugging is a construction method in which a slurry prepared by mixing grouting materials in a certain ratio is pressed into the voids behind the tunnel surrounding rock or lining wall through a certain method, and after coagulation and hardening, it plays the role of water plugging and strengthening the surrounding rock.

[0003] Currently, the general structure of the existing water plugging and grouting device is as follows: A cement tank is installed and fixed on a mobile trolley, and a grouting pump is also installed and fixed on the mobile trolley. The feeding port of the grouting pump is connected to the bottom discharging port of the cement tank through a grouting pipe, and a grouting nozzle is connected to the discharging port of the grouting pump through a grouting pipe. After aligning the grouting nozzle with the void behind the tunnel surrounding rock or lining wall, starting the grouting pump can implement the grouting operation.

[0004] It is not difficult to see that the existing water plugging and grouting device still has certain deficiencies in use: The cement slurry is prone to precipitation when stored in the cement tank for a long time, which will lead to different concentrations of the cement slurry injected into the voids, thus affecting the grouting effect; and after emptying the cement slurry in the cement tank, it is not convenient to wash the internal space of the cement tank. Content of the Utility Model

[0025] The following further describes the present utility model in detail with reference to the drawings.

[0026] A water plugging and grouting device for tunnel engineering, comprising:

[0027] Trolley 1, which is an existing device in common knowledge and has a structure as shown in Figure 1 and 2 the figure;

[0028] Agitating tank 2, grouting pipe 3, grouting pump 4 and grouting nozzle 5; the agitating tank 2 is a circular tank structure with an open top, and a sewage outlet 17 with a valve is arranged at the bottom. There are also three support legs 18 fixedly connecting the bottom to the chassis of the trolley 1. After the grouting pump 4 is installed and fixed on the trolley 1, the feeding port is connected to the bottom of the agitating tank 2 through the grouting pipe 3, and the discharging port is also connected with a grouting nozzle 5 through the grouting pipe 3;

[0029] Washing and agitating mechanism, including mounting bracket 6, motor 14, main water pipe 7, branch water pipes 8, transfer water tank 9, stainless steel wire brush bristles 10, strip plate brush 13 and adapter pipe 11; the mounting bracket 6 is installed and fixed on the top of the agitating tank 2, the top of the main water pipe 7 penetrates and is rotatably connected to the mounting bracket 6, the motor 14 is installed and fixed on the outer wall of the agitating tank 2, and the output shaft is drivingly connected to the top of the main water pipe 7 (the specific structure of the driving connection is as Figure 3 and 4 shown as "driving connection through belt pulleys and transmission belts"), the top of the main water pipe 7 is rotatably sleeved with an adapter pipe 11 fixed on the mounting bracket 6. The mounting bracket 6 is a flat plate structure. Nine branch water pipes 8 are connected to the main water pipe 7. The branch water pipes 8 are evenly arranged in three vertical rows along the circumferential direction of the main water pipe 7. The other ends of the three branch water pipes 8 in the same vertical row are detachably connected to the same transfer water tank 9. A plurality of water spraying holes 12 are evenly reserved on the side wall of the transfer water tank 9 facing away from the branch water pipes 8, and at the same time, the side surface is also covered with stainless steel wire brush bristles 10. The strip plate brush 13 washes the inner bottom wall of the agitating tank 2 and one end is fixedly connected to the bottom of the transfer water tank 9.

[0030] It is worth mentioning that an adapter tube sleeve 15 is formed on the side wall of the transfer water tank 9 facing the branch water pipes 8. After the adapter tube sleeve 15 is fitted and sleeved on the end of the branch water pipe 8, a sealing ring is clamped between the two, and the two are also fixed together by screws 16.

[0031] When this embodiment is specifically implemented: as Figure 1 and 2 shown, the prepared cement slurry is poured into the agitating tank 2, and the motor 14 is started to drive the main water pipe 7 and the branch water pipes 8 thereon to rotate at a low speed, so that continuous agitation effect can be implemented on the cement slurry, and the cement slurry is not easy to precipitate. After the grouting pump 4 is started, the cement slurry will be pumped into the grouting nozzle 5. After the grouting nozzle 5 is aligned with the void behind the tunnel surrounding rock or lining wall, the grouting operation can be carried out.

[0032] After the grouting operation is completed and the cement slurry in the mixing tank 2 is emptied, at this time, use a water delivery hose to connect the adapter pipe to the water pump. After starting the water pump, clear water will be pumped into the main water pipe 7, then enter the transfer water tank 9 through the straight pipe 8, and be sprayed onto the inner wall of the mixing tank 2 through each spray hole 12. At the same time, the motor 14 will drive the transfer water tank 9 and the strip brush 13 to rotate slowly in contact with the inner wall of the mixing tank 2, so as to implement a convenient and effective washing effect on the inner wall of the mixing tank 2.

[0033] After the stainless steel wire bristles 10 on the stainless steel wire bristle brush and the strip brush 13 have been used for a long time, the bristles will wear out and the washing effect will become poor. At this time, the transfer water tank 9 can be directly disassembled, and a new transfer water tank 9 with stainless steel wire bristles 10 and the strip brush 13 can be installed.

[0034] The above describes the present invention and its implementation manners. Such a description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present invention, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
