Description

Technical Field

[0001] The utility model relates to the technical field of tunnel grouting, in particular to a tunnel curtain grouting construction device for crossing a water-rich area. Background Art

[0002] When a tunnel crosses a water-rich stratum, water inrush and sudden water gushing are extremely likely to occur, as well as roof fall, local or large-area collapse of the heading face, resulting in safety accidents such as tunnel collapse and support deformation. How to take effective prevention and control measures to ensure construction safety and quality is the primary task of tunnel engineering construction. Curtain grouting is an effective means for pre-reinforcement of a tunnel crossing a water-rich soft surrounding rock. The purpose of tunnel curtain grouting construction is to form a concrete anti-seepage wall similar to a curtain to cut off water flow, so as to achieve the purposes of anti-seepage and leakage stoppage and enhancing the bearing capacity of the tunnel. Most of the existing grouting schemes are to drill holes first and then grout, and tools need to be frequently replaced, which is rather inconvenient. Content of the Utility Model

[0003] The utility model aims to overcome the deficiency that tools need to be frequently replaced in the prior art scheme of drilling holes first and then grouting, and provides a tunnel curtain grouting construction device for crossing a water-rich area, which integrates drilling and grouting.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A tunnel curtain grouting construction device for crossing a water-rich area includes a hand-held pipe, a drilling assembly and a grouting assembly. The drilling assembly is installed in the hand-held pipe. One end of the hand-held pipe is provided with an extension hole, and the drilling assembly corresponds to the extension hole. The grouting assembly is installed in the hand-held pipe and corresponds to the extension hole.

[0006] The hand-held pipe is used for holding to carry out grouting work. The drilling assembly installed in the hand-held pipe can extend out from the extension hole at the upper end of the hand-held pipe to drill holes in the tunnel. After the drilling is completed, the drilling assembly retracts into the hand-held pipe. After extending out from the extension hole through the grouting assembly and extending into the holes in the tunnel, grouting is carried out on the holes to be grouted, achieving the purpose of integrating drilling and grouting.

[0007] Preferably, the drilling assembly includes a pneumatic cylinder 1 and a drilling machine. The drilling machine is connected to the pneumatic end of the pneumatic cylinder 1, and the upper end of the drilling machine corresponds to the extension hole. The drill bit at the upper end of the drilling assembly corresponds to the extension hole. Driven by the pneumatic cylinder 1, the drill bit can be pushed out of the extension hole to carry out drilling work. It is only necessary to fit the top end of the hand-held pipe to the tunnel curtain, without manually pushing the drilling machine to drill holes. The upper end of the drilling machine is driven by the pneumatic cylinder 1 to extend out, which can ensure more uniform thrust, ensure a more standardized drilling process, and better control the drilling depth and drilling force. Such a design can drill holes better.

[0008] Preferably, a drainage plate is provided inside the handheld pipe. The drainage plate is in a horn shape. The end with a larger diameter of the drainage plate is connected to the inner wall of the handheld pipe, and the end with a smaller diameter of the drainage plate corresponds to the upper end of the drilling machine. Drainage holes are provided on the handheld pipe, and the drainage holes are located near the end with a larger diameter of the drainage plate. When drilling a tunnel curtain hole, substances such as mud are likely to exist in the hole. After drilling, the mud in the hole needs to be drained. Since the handheld pipe is closely attached to the wall, when the pneumatic cylinder 1 drives the drilling machine to retract, the mud and accumulated water in the hole will flow into the handheld pipe and need to be drained in time. Therefore, drainage holes are opened on the handheld pipe to drain the liquid in the handheld pipe. At the same time, a drainage plate is installed inside the handheld pipe. The drainage plate is in a horn shape. The horn-shaped drainage plate can guide the liquid to the end with a larger diameter at the bottom of the drainage plate and flow out through the drainage hole. The upper end of the drainage plate is the end with a smaller diameter, and the upper end corresponds to the drill bit of the drilling machine. The liquid is not easy to flow to the bottom end of the handheld pipe. Such a design is convenient for guiding the liquid to flow out.

[0009] Preferably, an installation frame is installed at the upper end of the handheld pipe. The installation frame is communicated with the handheld pipe. The drilling assembly includes a transverse movement plate, a pneumatic cylinder 2, and a grouting pipe. A sliding groove is provided on the transverse movement plate, and a sliding block is provided inside the installation frame. The transverse movement plate is slidably connected to the installation frame through the cooperation of the sliding block and the sliding groove. The pneumatic cylinder 2 is installed on the transverse movement plate, and the pneumatic end of the pneumatic cylinder 2 is connected to the grouting pipe. The grouting pipe is in an L shape. One end of the grouting pipe corresponds to the protruding hole. A lifting groove is provided on the installation frame, and the other end of the grouting pipe passes through the lifting groove and is located outside the installation frame. An installation frame is installed at the upper end of the handheld pipe, and a grouting assembly is installed inside the installation frame. The transverse movement plate of the grouting assembly can move inside the installation frame, driving the pneumatic cylinder 2 to move towards the protruding hole of the handheld pipe, driving the pneumatic cylinder 2 to move to correspond to the protruding hole. After corresponding, the pneumatic cylinder 2 extends to drive the functional grouting pipe to rise, and one end of the grouting pipe extends out of the handheld pipe and is inserted into the hole to be grouted for grouting. The other end of the grouting pipe passes through the lifting groove and is located outside the installation frame. The end located outside is connected to a grouting pump, and grouting is carried out into the hole through the grouting pipe. Such a design is convenient for tool conversion.

[0010] Preferably, a pneumatic cylinder 3 is installed inside the installation frame, and a push plate is installed on the transverse movement plate. The pneumatic end of the pneumatic cylinder 3 is connected to the push plate. The transverse movement plate moves inside the installation frame by the pneumatic cylinder 3 pushing the push plate on the transverse movement plate to drive the transverse movement plate to move, and the transverse movement plate is pushed to correspond to the position below the protruding hole. Such a design is convenient for moving the transverse movement plate.

[0011] Preferably, two hand rings are installed on the hand-held tube, and the hand rings are staggered. In order to facilitate the hand-held tube to fit against the wall, two hand rings are installed on the hand-held tube for holding. The staggered hand rings can be better grasped, and such a design facilitates the holding of the hand-held tube.

[0012] The beneficial effects of the present utility model are: concentrating drilling and grouting for work can better drill holes, facilitate guiding the accumulated liquid to flow out, facilitate tool conversion, facilitate moving the transverse moving plate, and facilitate holding the hand-held tube.
