Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of grouting devices, and particularly relates to an integrated grouting device for treating seepage water leakage and enhancing the structure of a tunnel wall. Background Technique
[0002] Most of the tunnels built in China, whether they are mountain tunnels, urban tunnels or underwater tunnels, inevitably have varying degrees of seepage water leakage problems. The saying "nine out of ten tunnels leak" summarizes the universality and pervasiveness of the seepage water leakage problems faced by existing operating tunnels. The seepage water leakage problems in tunnels not only endanger the safety of the tunnel structure itself, but also affect the driving safety and comfort of drivers. At present, there are different treatment methods for the seepage water leakage problems in tunnels in China according to different positions and types of seepage water leakage. For linear seepage water leakage, the treatment techniques mainly include chemical grouting for plugging leaks, external drainage with aluminum channels or PVC pipes, and hidden PVC pipe drainage methods; for point-type seepage water leakage, the treatments include surface plugging, shallow hole grouting and buried pipe drainage; for surface-type seepage water leakage problems, the treatment methods are surface coating and shallow hole grouting.
[0003] Grouting equipment is often used in the treatment of seepage water leakage in tunnel walls. The treatment is carried out by injecting slurry into the gaps in the tunnel walls and then smoothly leveling the gaps. However, the structure of the grouting nozzle of the existing grouting equipment is relatively single. On the one hand, the grouting nozzle is only used for injecting slurry, and separate tools are required for the surface leveling treatment of the wall gaps. Moreover, there is a phenomenon of overflow of the joint filling slurry in the wall gaps during the grouting process. On the other hand, the grouting port of the grouting nozzle is small, and the grouting operation efficiency for long leakage gaps on the tunnel wall is low.
[0004] Therefore, there is a need for an integrated grouting device for treating seepage water leakage and enhancing the structure of a tunnel wall to solve the problems of the single structure and function of the grouting nozzle of the grouting equipment in the prior art and its poor adaptability to complex grouting application scenarios. Content of the Utility Model
[0005] The purpose of the utility model is to provide an integrated grouting device for treating seepage water leakage and enhancing the structure of a tunnel wall to solve the problems put forward in the above background technique.
[0006] To achieve the above object, the present utility model provides the following technical solutions: An integrated grouting device for treating seepage water leakage and enhancing the structure of a tunnel wall, including a grouting pump unit. One end of the grouting pump unit is provided with a grouting head. The surface of the grouting head is flange-connected with a grouting conduit. The end of the grouting conduit is fixed with a grouting nozzle. The surface of the grouting nozzle is provided with a crack filling and surface plastering mechanism. The crack filling and surface plastering mechanism includes a pressing shell, a crack filling and plastering flat plate, an extended grouting groove, and an adsorption magnet. The pressing shell is sleeved outside the grouting nozzle. The crack filling and plastering flat plate is embedded and fixed in the inner cavity of the pressing shell. The extended grouting groove is opened on one side surface of the crack filling and plastering flat plate. The adsorption magnet is sleeved and fixed on the surface of the grouting nozzle. The lower end of the pressing shell extends and is provided with a waste material collecting box.
[0007] It should be noted in the solution that a material guiding slope block is provided at the lower end of the crack filling and plastering flat plate, and a material dropping port is opened at the lower edge of the rear surface of the pressing shell where the material guiding slope block is located.
[0008] Further, it is worth noting that a sealing plug is embedded at the material dropping port of the pressing shell. A waste material collecting groove is arranged inside the waste material collecting box. The material dropping port of the pressing shell is communicated with the waste material collecting groove of the waste material collecting box.
[0009] Furthermore, it should be noted that the adsorption magnets are distributed behind the pressing shell, and the adsorption magnets are magnetically adsorbed to the pressing shell.
[0010] As a preferred implementation manner, one end of the grouting nozzle extends into the extended grouting groove of the crack filling and plastering flat plate, and the grouting nozzle is slidably connected to the rear surface of the pressing shell.
[0011] As a preferred implementation manner, a waste material receiving port is opened on the front surface of the pressing shell. A connecting material port is arranged between the pressing shell and the waste material collecting box. The waste material receiving port of the pressing shell is communicated with the connecting material port. The connecting material port is communicated with the waste material collecting groove of the waste material collecting box. A pushing trolley is arranged below the grouting pump unit. An operation handle is fixed on the rear surface of the pressing shell.
[0012] Compared with the prior art, the integrated grouting device for treating seepage water leakage and enhancing the structure of a tunnel wall provided by the present utility model has at least the following beneficial effects:
[0013] ⑴ Through the provided crack filling and plastering mechanism, the pressing shell and the crack filling and plastering flat plate are arranged outside the part of the tunnel wall to be filled, which can reduce the trouble of the crack filling mortar overflowing during the grouting process. At the same time, the crack filling and plastering flat plate can perform a smooth plastering treatment on the tunnel wall during the crack filling process, thus eliminating the cumbersome steps of separately obtaining a scraper tool. In addition, controlling the position change of the grouting nozzle can fill the crack filling mortar into the pressing shell and activate the extended grouting groove on the surface of the crack filling and plastering flat plate, so that the grouting nozzle can adapt to efficiently grout the longer cracks on the tunnel wall.
[0014] ⑵ Through the provided surplus material collection box, when the crack filling and plastering flat plate performs the plastering treatment, the excess crack filling mortar will pass through the surplus material receiving port and the connecting material port and be collected in the surplus material collection groove of the surplus material collection box, so as to achieve the purpose of collecting the excess crack filling mortar and reducing waste.

Detailed Embodiment
[0020] The following further describes the present utility model in conjunction with embodiments.
[0021] Please refer to Figures 1-4, the present utility model provides an integrated grouting device for treating seepage water leakage and strengthening the structure of a tunnel wall, which includes a grouting pump unit 1. One end of the grouting pump unit 1 is provided with a grouting head 3. A grouting conduit 4 is flange-connected to the surface of the grouting head 3. A grouting nozzle 5 is fixed at the end of the grouting conduit 4. A crack filling and surface smoothing mechanism is arranged on the surface of the grouting nozzle 5. The crack filling and surface smoothing mechanism includes a pressing shell 6, a crack filling and smoothing plate 7, an extended grouting groove 8 and an adsorption magnet 17. The pressing shell 6 is sleeved outside the grouting nozzle 5. The crack filling and smoothing plate 7 is embedded and fixed in the inner cavity of the pressing shell 6. The extended grouting groove 8 is opened on one side surface of the crack filling and smoothing plate 7. The adsorption magnet 17 is sleeved and fixed on the surface of the grouting nozzle 5. A surplus material collecting box 11 is extended and arranged at the lower end of the pressing shell 6.
[0022] Further, as shown in Figure 1 , Figure 2 and Figure 3 , it is specifically worth noting that a material guiding slope block 14 is arranged at the lower end of the crack filling and smoothing plate 7, and a material dropping port 15 is opened at the rear surface of the pressing shell 6 at the lower edge of the material guiding slope block 14.
[0023] Further, as shown in Figure 3 , it is specifically worth noting that a sealing plug 16 is embedded at the material dropping port 15 of the pressing shell 6. A surplus material collecting groove 12 is arranged inside the surplus material collecting box 11. The material dropping port 15 of the pressing shell 6 is communicated with the surplus material collecting groove 12 of the surplus material collecting box 11.
[0024] This solution has the following working process: Before use, the grouting nozzle 5 and the pressing shell 6 are combined. When using for crack filling grouting, the pressing shell 6 is placed on the tunnel wall and the grouting nozzle 5 is aligned with the part to be crack-filled. The crack filling slurry in the grouting pump unit 1 is guided through the grouting head 3 and the grouting conduit 4 and sprayed out from the grouting nozzle 5 to grout the cracks on the tunnel wall. The arrangement of the pressing shell 6 and the crack filling and smoothing plate 7 outside the part to be filled on the tunnel wall can reduce the trouble of the crack filling slurry overflowing during the grouting process. At the same time, the crack filling and smoothing plate 7 can perform a smooth surface treatment on the tunnel wall during the crack filling process, thus saving the cumbersome steps of separately fetching a scraper tool. Also, after the adsorption magnet 17 on the surface of the grouting nozzle 5 is separated from the adsorption of the pressing shell 6, one end of the grouting nozzle 5 moves into the inside of the pressing shell 6. In this way, the crack filling slurry can be filled into the inside of the pressing shell 6 and the extended grouting groove 8 on the surface of the crack filling and smoothing plate 7 can be enabled, so that the grouting nozzle 5 can adapt to efficiently grout longer cracks on the tunnel wall.
[0025] According to the above working process, it can be known that the pressing shell 6 and the joint-filling and smoothing plate 7 are arranged outside the part of the tunnel wall to be filled, which can reduce the trouble of the joint-filling mortar overflowing during the grouting process. At the same time, the joint-filling and smoothing plate 7 can perform a smooth finishing treatment on the tunnel wall during the joint-filling process, thus saving the cumbersome steps of separately using a scraper tool. In addition, controlling the position change of the grouting nozzle 5 can fill the joint-filling mortar into the pressing shell 6 and activate the extended grouting groove 8 on the surface of the joint-filling and smoothing plate 7, so that the grouting nozzle 5 can adapt to the efficient grouting treatment of the longer gaps in the tunnel wall.
[0026] Further, as shown in Figure 1 , Figure 2 and Figure 4 , it is specifically noted that the adsorption magnet 17 is distributed behind the pressing shell 6, and the adsorption magnet 17 is magnetically adsorbed to the pressing shell 6.
[0027] Further, as shown in Figure 4 , it is specifically noted that one end of the grouting nozzle 5 extends into the extended grouting groove 8 of the joint-filling and smoothing plate 7. The grouting nozzle 5 is slidably connected to the rear surface of the pressing shell 6. During the finishing treatment of the joint-filling and smoothing plate 7, the excess joint-filling mortar will be collected into the surplus material collection groove 12 of the surplus material collection box 11 through the surplus material receiving port 9 and the connecting material port 10, so as to achieve the purpose of collecting the excess joint-filling mortar and reducing waste.
[0028] Further, as shown in Figure 1 , it is specifically noted that the front surface of the pressing shell 6 is provided with a surplus material receiving port 9. A connecting material port 10 is arranged between the pressing shell 6 and the surplus material collection box 11. The surplus material receiving port 9 of the pressing shell 6 is communicated with the connecting material port 10, and the connecting material port 10 is communicated with the surplus material collection groove 12 of the surplus material collection box 11. A pushing trolley 2 is arranged at the lower part of the grouting pump unit 1, and an operation handle 13 is fixed to the rear surface of the pressing shell 6.
[0029] In summary: The pressing shell 6 and the joint-filling and smoothing plate 7 are arranged outside the part of the tunnel wall to be filled, which can reduce the trouble of the joint-filling mortar overflowing during the grouting process. At the same time, the joint-filling and smoothing plate 7 can perform a smooth finishing treatment on the tunnel wall during the joint-filling process, thus saving the cumbersome steps of separately using a scraper tool. In addition, controlling the position change of the grouting nozzle 5 can fill the joint-filling mortar into the pressing shell 6 and activate the extended grouting groove 8 on the surface of the joint-filling and smoothing plate 7, so that the grouting nozzle 5 can adapt to the efficient grouting treatment of the longer gaps in the tunnel wall. During the finishing treatment of the joint-filling and smoothing plate 7, the excess joint-filling mortar will be collected into the surplus material collection groove 12 of the surplus material collection box 11 through the surplus material receiving port 9 and the connecting material port 10, so as to achieve the purpose of collecting the excess joint-filling mortar and reducing waste.

Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
