Description

Technical Field

[0001] This utility model belongs to the technical field of clamping and fixing devices, specifically relating to a water pipe clamping and fixing device for grouting the arch of a water-containing cavity. Background Technology

[0002] When encountering groundwater during mountain tunnel construction, drainage is generally the primary method. Groundwater is a common hazard in highway tunnel construction, especially in karst tunnels in karst terrain. Typically, multiple drainage pipes are pre-installed, allowing water to seep through large fissures and cavities in the initial support section. Before secondary lining construction, a high-level water intake pipe is pre-installed in this section, and then the pre-installed drainage pipes are closed. This allows water to fill the cavity above the initial support section up to the inlet of the high-level water intake pipe, from which the water is led out. Cement grout is then injected layer by layer using the existing drainage pipes to raise the water level. Current technologies for fixing water intake pipes at the tunnel's high end primarily use grouting and mechanically assisted fixing methods. However, these methods suffer from complex structures, poor fixing effectiveness, and a certain risk of detachment.

[0003] In view of this, in order to solve the above-mentioned technical problems, the inventors have proposed a water pipe clamping and fixing device for grouting the arch of a water-containing cavity. Utility Model Content

It is simple to operate, provides good fixing effect, has a reasonable structural design, and is inexpensive. The specific solution is as follows: A water pipe clamping and fixing device for grouting of a water-containing cavity arch includes a mounting base. The mounting base has a water pipe through hole in the middle and bolt mounting holes on both sides. Vertical plates are respectively provided on the mounting base on both sides of the water pipe through hole. Guide slide rods are symmetrically provided between the opposite sides of the two vertical plates. Support plates are respectively provided on the opposite sides of the two vertical plates. Sliding holes that can slide on the guide slide rods are respectively provided at both ends of the two support plates. Clamping blocks are respectively provided on the opposite sides of the two support plates. Threaded holes are respectively provided on the two vertical plates. Screws are respectively provided vertically on the side of the two support plates near the vertical plates. The two screws pass through the corresponding threaded holes and extend to the outside of the support plates. Rotary handles are matched on the screws on the outside of the support plates.

[0005] Furthermore, the clamping block is composed of multiple parallel V-shaped clamping elements.

[0006] Furthermore, each of the multiple V-shaped clamping components consists of two symmetrically arranged clamping blocks. Each of the clamping blocks has a first ball head mounting hole on the side near the support plate. A first connecting ball head is matched in the first ball head mounting hole. A fixing rod is fixedly connected to the first connecting ball head on the side near the support plate. The free end of the fixing rod moves through the support plate and extends to the outside of the support plate. A fixing cap is fixedly provided on the fixing rod on the outside of the support plate. A compression spring is sleeved on the fixing rod between the clamping block and the support plate.

[0007] Furthermore, a second ball head mounting hole is provided on the clamping block on one side of the first ball head mounting hole, and a second connecting ball head is matched in the second ball head mounting hole. A pin is fixedly connected to the second connecting ball head on the side near the support plate, and the free end of the pin moves through the support plate and extends to the outside of the support plate.

[0008] Furthermore, rubber anti-slip pads are fixedly connected to the side of the clamping blocks away from the support plate by screws.

[0009] Furthermore, threaded cylinders suitable for screws are fixedly connected to the vertical plates on the outer sides of the two threaded holes.

[0010] Furthermore, thrust bearings are connected to the ends of the two threaded cylinders away from the vertical plate, and the rotating handle is connected to the side of the thrust bearing away from the vertical plate.

[0011] The beneficial effects of this utility model are: This utility model discloses a water pipe clamping and fixing device for grouting the arch of a water-containing cavity. By setting up an installation base, a vertical plate, a support plate, a clamping block between the support plates, a screw, and a rotating handle, the installation base can be fixed to the tunnel wall with bolts. Then, by rotating the two rotating handles respectively, the V-shaped clamping block abuts against both sides of the water pipe to form a limiting clamping and fixing of the water pipe, effectively preventing the water pipe from falling off and affecting the subsequent construction period. It has the advantages of simple operation, low cost, and good fixing effect. In addition, it can be disassembled for secondary recycling, making it highly practical. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] See Figure 1-5 A water pipe clamping and fixing device for grouting the arch of a water-containing karst cavity includes a mounting base 1. The mounting base 1 has a water pipe passage hole 2 in the middle and bolt mounting holes 3 on both sides. When installing the base 1, the water pipe passage hole 2 is located outside the water pipe, and the mounting base 1 is fixed to the tunnel wall by bolts passing through the bolt mounting holes 3. Vertical plates 4 are respectively installed on the mounting base 1 on both sides of the water pipe passage hole 2. Reinforcing ribs are welded to the mounting base 1 on both sides of the vertical plates 4, and the two vertical plates 4 are positioned opposite each other. The device is equipped with guide slide rods 5, of which there are two guide slide rods 5 on the same side and they are spaced apart vertically. Support plates 6 are provided on opposite sides of the two upright plates 4. Sliding holes that can slide on the guide slide rods 5 are opened at both ends of the two support plates 6. Clamping blocks 7 are provided on opposite sides of the two support plates 6. Threaded holes are opened on the two upright plates 4. Screws 8 are vertically provided on the side of the two support plates 6 near the upright plates 4. The two screws 8 pass through the corresponding threaded holes and extend to the outside of the support plates 6. A rotating handle 9 is matched on the screws 8 on the outside of the support plates 6.

[0019] The preferred clamping block 7 is composed of multiple parallel V-shaped clamping members, wherein the multiple V-shaped clamping members can better clamp and fix the water pipe.

[0020] The preferred V-shaped clamping components are each composed of two symmetrically arranged clamping blocks 701. Each clamping block 701 has a first ball head mounting hole on the side of the support plate 6. A first connecting ball head 10 is matched in the first ball head mounting hole. A fixing rod 11 is fixedly connected to the side of the first connecting ball head 10 near the support plate 6. The free end of the fixing rod 11 moves through the support plate 6 and extends to the outside of the support plate 6. A fixing cap 12 is fixedly installed on the fixing rod 11 on the outside of the support plate 6. A compression spring 13 is sleeved on the fixing rod 11 between the clamping block 701 and the support plate 6. The arrangement of the first connecting head 10 and the fixing rod 11 connected thereto, as well as the compression spring 13, allows the clamping block 701 to perform a small-amplitude adaptive angle through the first connecting ball head 10 when the mounting base 1 and the water pipe are not perpendicular to each other. This ensures that the clamping block 701 can fit as close as possible to the water pipe, providing better clamping and fixation of the water pipe and enhancing environmental adaptability.

[0021] A second ball head mounting hole is provided on the clamping block 701 on one side of the preferred first ball head mounting hole. A second connecting ball head is matched in the second ball head mounting hole. A pin 14 is fixedly connected to the second connecting ball head on the side near the support plate 6. The free end of the pin 14 moves through the support plate 6 and extends to the outside of the support plate 6.

[0022] The preferred clamping blocks 701 are respectively fixed with rubber anti-slip pads 15 by screws on the side opposite to the support plate 6. The rubber anti-slip pads 15 can further realize the clamping and fixing of the water pipe by the clamping blocks 701.

[0023] Preferably, threaded cylinders 16 suitable for screw 8 are fixedly connected to the vertical plates 4 on the outer sides of the two threaded holes, wherein the setting of threaded cylinders 16 can further ensure the stability of screw 8.

[0024] Preferably, the two threaded cylinders 16 are connected to thrust bearings at the ends away from the vertical plate 4, and the rotating handle 9 is connected to the side of the thrust bearing away from the vertical plate 4. The thrust bearings make it easier to rotate the handle 9.

[0025] The working principle of this utility model is as follows: First, holes are drilled in four directions of the water pipe and expansion nuts are placed. Then, the mounting base 1 is fixed to the tunnel wall with bolts. Then, the rotating handles 8 on both sides are manually turned. As the rotating handles 8 rotate, they push the support plate 6 towards the water pipe. When the multiple clamping blocks 701 at the front end of the support plate 6 press against the side wall of the water pipe, the water pipe can be clamped and fixed. During this process, due to the unevenness of the tunnel wall structure, it may be impossible to ensure that the mounting base 1 is perpendicular to the water pipe when it is installed. Therefore, when the rotating handles 8 are turned to press the multiple clamping blocks 701 on both sides against the water pipe, the first connecting ball head 10 and compression spring 13 set on the side of the clamping block 701 near the support plate 6 can make the multiple clamping blocks 701 adjust their angle slightly to make them as close as possible to the side wall of the water pipe. The rubber anti-slip pads 15 can further prevent the water pipe from slipping, thereby ensuring the stability of the clamping and fixing of the water pipe.

[0026] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.

[0027] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
