[0001] This utility model relates to the field of civil engineering technology, and in particular to a portable diamond-shaped positioning device for hanging geotextile in tunnels. Background Technology

[0002] High-speed rail construction is a requirement of the times for scientific development, and as a new mode of transportation in modern society, it has extremely obvious advantages. With the current vigorous construction, extremely high requirements are placed on construction standards and quality. In tunnel waterproofing and drainage, water leakage is a persistent problem in tunnel engineering. Geotextiles are typically laid on the inner wall of the tunnel using pre-drilled nails to prevent water from seeping into the tunnel. However, existing geotextiles, after being laid, are compressed and limited with hot-melt gaskets to ensure stability. This results in uneven spacing between the hot-melt gaskets, preventing the geotextile from adhering tightly to the initial support surface of the tunnel, causing uneven laying, affecting waterproofing effectiveness, and increasing the risk of leakage. Therefore, this utility model proposes a portable diamond-shaped positioning device for hanging tunnel geotextiles. Utility Model Content

[0003] The purpose of this utility model is to address the problem in the background technology that, after the geotextile is laid, hot-melt gaskets are used to press and limit the geotextile to ensure its stability. This results in uneven spacing of the hot-melt gaskets, which prevents the geotextile from adhering tightly to the initial support surface of the tunnel, causing uneven laying, affecting the waterproofing effect, and increasing the risk of leakage. The present invention proposes a portable diamond-shaped positioning device for hanging tunnel geotextile.

[0026] Example

[0027] like Figure 1 and Figure 2 As shown, the present invention proposes a portable diamond-shaped positioning device for mounting geotextile in tunnels, comprising: a frame 1 for supporting the geotextile, with multiple connecting rods 2 movably passing through the frame 1 to guide the connecting rods 2 and enable them to move stably; a locking block 3 is fixedly connected to one end of each connecting rod 2, and the locking block 3 is a ring structure that can stably engage with the nails; and a support assembly 4 disposed between the frames 1 to limit the locking block 3, thereby facilitating stable support of the geotextile between the nails.

[0028] like Figure 2 and Figure 4 As shown, the support assembly 4 includes a support frame 41, on which a through groove 42 is provided. A guide rod 43 is fixedly installed inside the through groove 42. A connecting rod 44 is movably sleeved on the outer wall of the guide rod 43, which can guide the connecting rod 44 and make the connecting rod 44 move stably. One end of the connecting rod 44 is fixedly connected to one end of the connecting rod 2, which facilitates the movement of the locking block 3 at one end of the connecting rod 2. A spring 45 is sleeved on the outer wall of the guide rod 43. One end of the spring 45 is fixedly connected to the support frame 41, and the other end of the spring 45 is fixedly connected to the connecting rod 44, which can push the locking block 3 to be stably locked on the outer wall of the nail, thereby providing stable support for the geotextile.

[0029] like Figure 2 and Figure 4 As shown, a sliding groove 5 is provided on the inner wall of the through groove 42, and a slider 6 is slidably arranged inside the sliding groove 5. The slider 6 is fixedly connected to the sleeve rod 44 and can guide the sleeve rod 44 so that the sleeve rod 44 can move stably.

[0030] like Figure 1 and Figure 4 As shown, rubber pads 7 are fixedly installed on both sides of the sleeve rod 44 to increase friction and facilitate manual pushing of the sleeve rod 44.

[0031] Further, such as Figure 3 As shown, the four corners of the frame 1 are respectively provided with grooves 8, and the grooves 8 are set with an arc structure to facilitate the collision between the frame 1 and the card block 3.

[0032] Secondly, frame 1 is designed with a rhomboid structure, which provides good support stability and improves the stability of the geotextile support.

[0033] Furthermore, the support frame 41 is designed with a cross-shaped structure, which can provide stable support for the geotextile between the nails.

[0034] The working principle of this embodiment is as follows: when supporting the geotextile, the geotextile is fitted onto the pre-nailed nails, and a hot melt pad is fitted onto the nails to compress the geotextile.

[0035] Then, one of the locking blocks 3 is engaged with the outer wall of the nail, and the rubber pad 7 pulls the connecting rod 44 to slide on the outer wall of the guide rod 43. The connecting rod 44 drives the locking block 3 at one end of the connecting rod 2 to move, and places the frame 1 between the pre-installed nails. After that, the rubber pad 7 is released, and the elastic force of the spring 45 pushes the connecting rod 44 to slide on the guide rod 43. The connecting rod 44 drives the locking block 3 to engage with the outer wall of the pre-installed nail through the connecting rod 2, thereby fixing the hot melt gasket to the outer wall of the nail. This can stably position the hot melt gasket, while supporting the geotextile, so that the geotextile is tightly attached to the tunnel wall, avoiding the geotextile from becoming hollow and accumulating water, facilitating installation, and improving the waterproof effect of the geotextile.

[0036] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
