[0002] Water inrush, also known as water burst, is the phenomenon of groundwater continuously flowing into the site during mining, excavation of foundation pits, or underground caverns in rock masses below the groundwater level. It is a common engineering geological problem encountered in construction projects. Water inrush not only creates construction difficulties but is also a major cause of instability in the surrounding rock of underground caverns, seepage damage in dam foundation pits, and slope collapse.

[0003] Currently, 80% of tunnel projects encounter groundwater hazards during construction. Water inrush is the most common geological hazard during tunnel construction. Sudden, massive water inrush during tunnel construction can be devastating, causing equipment and personnel accidents, even forcing work to stop and delaying the project. Furthermore, water leakage and water inrush during construction are difficult and expensive to handle, and they pose a significant engineering geological risk, hindering the normal progress of surface engineering.

[0030] See also Figure 1 、 Figure 2and Figure 3 The present application provides a tunnel construction water gushing treatment device, comprising a guide rod 1, a grouting pipe 2, and a clamping claw 3; the guide rod 1 is a solid rod made of high-strength plastic.

[0031] An airbag cavity 11 is provided at the front end of the guide rod 1. The outer cavity wall of the airbag cavity 11 is made of plastic with lower strength and is designed to be thinner. An airbag 4 is provided in the airbag cavity 11. An air guide channel 12 is provided in the guide rod 1. One end of the air guide channel 12 is connected to the airbag 4, and the other end extends to the rear end of the guide rod 1, and a quick connector is provided. In this way, it can be connected to an external air pumping device through the quick connector. When the air supply device is running, the airbag 4 can be inflated through the air guide channel 12. The airbag 4 is inflated and expanded, which can break the outer cavity wall of the airbag cavity 11.

[0032] The guide rod 1 is provided with a guide hole 13, which is coaxial with the guide rod 1 and extends through the front and rear ends of the guide rod 1. The grouting pipe 2 is slidably installed in the guide hole 13, so that the grouting pipe 2 can move forward and backward along the guide hole 13. The guide hole 13 is surrounded by guide channels 14 spaced apart along its circumference. There are two, three, or four guide channels 14. Preferably, there are four guide channels 14, each of which is connected to the guide hole 13. A claw 3 is slidably installed in each guide channel 14. The claw 3 is made of metal and has a sharp front end, which is more convenient for insertion into the soil. The rear end of the claw 3 is hinged to the grouting pipe 2. The front end of the guide rod 1 is provided with an extension hole 15 connected to the guide channel 14. The rear end of the guide rod 1 is provided with a fastening assembly 5 for fixing the position of the grouting pipe 2.

[0033] In the initial state of the device, the claw 3 is retracted into the guide channel 14 .

[0034] When using this device to block water gushing, find the water gushing point, then push the guide rod 1 and insert it into the water gushing point. When the insertion depth reaches the set position, the guide rod 1 is fixed, and then the grouting pipe 2 is pushed forward. The grouting pipe 2 pushes the claw 3 to move forward, and then the front end of the claw 3 continuously extends outward from the extension hole 15 and inserts into the soil around the water gushing point. The grouting pipe 2 is pushed to the specified position, and the claw 3 opens outward in a fan shape, and the front end of the grouting pipe 2 extends from the front end of the guide rod 1. The grouting pipe 2 is then fixed by the fastening assembly 5. In this way, the guide rod 1 is firmly inserted into the hole of the water gushing. After that, air is inflated into the air bag 4 through the air guide channel 12. The air bag 4 expands and forms an expanded closed body at the front end of the claw 3, thereby effectively and quickly blocking the water gushing point of the tunnel.

[0035] The present application fixes the guide rod 1 in the water gushing hole by inserting the claw 3 into the soil around the water gushing hole, and then seals the water gushing point by inflating the air bag 4 at the front end of the guide rod 1. It is easy to use and effectively improves the efficiency of water gushing sealing. Furthermore, the sealing material can be injected into a deeper position of the water gushing point through the grouting pipe 2, thereby forming a more solid seal. Moreover, when encountering a smaller aquifer, the grouting pipe 2 is connected to the external water diversion pipe to divert the gushing water outward, effectively avoiding the construction area around the water gushing flow channel.

[0036] In this embodiment, the front end face of the guide rod 1 is provided with a slide rail with a T-shaped cross-section, and the bottom surface of the semi-conical head 6 is provided with a slide groove matching the shape of the slide rail. The semi-conical head 6 is slidably installed on the slide rail through the slide groove, so that the semi-conical head 6 can slide to both sides; there are two semi-conical heads 6, which together form a conical structure, so that the end of the guide rod 1 is relatively sharp, so that the guide rod 1 can be more conveniently inserted into the gushing water; a conical expansion cavity 61 is provided between the two semi-conical heads 6, and the bottom radius of the expansion cavity 61 matches the diameter of the grouting pipe 2. In this way, when the grouting pipe 2 extends forward into the expansion cavity 61, the two semi-conical heads 6 are driven to slide open to both sides, so that the grouting pipe 2 can be extended forward. At the same time, the setting of the semi-conical head 6 can effectively prevent soil from entering the grouting pipe 2 or the guide hole 13 during the insertion of the guide pipe, thereby ensuring that the grouting pipe 2 can be smoothly extended forward.

[0037] In this embodiment, a guide slope 16 is provided at the front end of the guide channel 14. In this way, when the grouting pipe 2 pushes the claw 3 to move forward, the claw 3 contacts the guide slope 16. Under the action of the guide slope 16, the claw 3 is more likely to open to both sides, effectively ensuring that the claw 3 opens outward smoothly.

[0038] In this embodiment, if Figure 4 As shown, the fastening assembly 5 includes a semicircular locking ring 51 and a locking bolt 52; the rear end of the guide rod 1 is constructed with a mounting cavity 17, and the locking ring 51 is installed in the mounting cavity 17. The volume of the mounting cavity 17 is larger than the volume of the locking ring 51, so that the locking ring 51 can move up and down, and the two ends of the locking ring 51 are respectively provided with connecting parts extending out of the guide rod 1, and the guide rod 1 is provided with a second connecting part corresponding to the position of the connecting part, and the connecting part and the second connection are connected by a locking bolt 52. In this way, when it is necessary to lock the grouting pipe 2, the locking bolt 52 is tightened, and the locking ring 51 moves downward, thereby holding the grouting pipe 2 tightly, thereby achieving the purpose of fixing the grouting pipe 2.

[0039] In some specific embodiments, the inner side of the locking ring 51 is constructed with latches. When the locking ring 51 hugs the grouting pipe 2, the latches bite into the grouting pipe 2, thereby effectively improving the connection strength between the locking ring 51 and the grouting pipe 2, and the grouting pipe 2 is fixed more firmly.
