Description

Technical Field

[0001] This utility model relates to the field of tunnel engineering technology, and in particular to a positioning structure for preventing the floating of tunnel drainage pipes. Background Technology

[0002] The tunnel drainage system is one of the important safeguards for high-speed railways to avoid operational defects. Currently, tunnel drainage pipes are generally installed between the tunnel lining and the secondary lining to drain water.

[0003] However, during the construction of drainage systems in high-speed railway tunnels, the drainage pipes are prone to floating and shifting during the pouring of concrete for the secondary lining after installation. This can lead to problems such as the longitudinal drainage slope not conforming to the design, and the tee pipes becoming detached or damaged, severely affecting the drainage effect. Current technologies often use wire to simply block the drainage pipes from floating, but this is ineffective; the wire is prone to instability, resulting in failure to secure the drainage pipes.

[0004] Therefore, based on the above-mentioned technical problems, those skilled in the art urgently need to develop a positioning structure to prevent tunnel drainage pipes from floating. Utility Model Content

[0005] The purpose of this invention is to provide a tunnel drainage pipe anti-floating positioning structure to solve the above problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model discloses a tunnel drainage pipe anti-floating positioning structure, comprising:

[0008] The bottom support has one end embedded in the side wall concrete adjacent to the tunnel drainage pipe, and the other end protruding from the concrete to support the tunnel drainage pipe.

[0009] The first embedded block and the second embedded block are embedded in the side wall concrete adjacent to the tunnel drainage pipe, and the second embedded block is embedded in the bottom concrete below the tunnel drainage pipe.

[0010] A metal sheet is connected between the first embedded block and the second embedded block. The metal sheet passes over the top of the tunnel drainage pipe to tightly fix the upper surface of the tunnel drainage pipe and prevent the tunnel drainage pipe from floating.

[0011] Furthermore, the metal sheet is fixedly connected to the first embedded block by bolts.

[0012] Furthermore, the second embedded block has a first perforation and a second perforation for the metal sheet to pass through.

[0013] Furthermore, after passing through the first perforation from top to bottom, the metal sheet continues to pass through the second perforation from bottom to top, and the metal sheet extending upwards out of the second perforation is fastened to the bottom concrete below the tunnel drainage pipe by screws.

[0014] Furthermore, an arc-shaped protrusion is provided on the lower surface of the second embedded block at a position between the first perforation and the second perforation.

[0015] Furthermore, the metal sheet covers the arc-shaped protrusion as it passes between the first and second perforations.

[0016] In the above technical solution, the anti-floating positioning structure for tunnel drainage pipe provided by this utility model has the following beneficial effects:

[0017] This device secures the two ends of the metal sheet of the tunnel drainage pipe by pre-embedding the first and second pre-embedding blocks in the tunnel lining concrete, making the metal sheet firmly fixed and not easy to fall off. The bottom support provides initial support for the tunnel drainage pipe, effectively preventing the tunnel drainage pipe from floating and shifting during the secondary lining concrete pouring.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-3 A tunnel drainage pipe anti-floating positioning structure, comprising:

[0026] The bottom support 1 has one end embedded in the side wall concrete adjacent to the tunnel drainage pipe, and the other end protruding from the concrete to support the tunnel drainage pipe, so as to effectively support the tunnel drainage pipe in the initial stage.

[0027] The first embedded block 2 and the second embedded block 3 are embedded in the side wall concrete adjacent to the tunnel drainage pipe, and the second embedded block 3 is embedded in the bottom concrete below the tunnel drainage pipe.

[0028] A metal sheet 4 is connected between the first embedded block 2 and the second embedded block 3. The metal sheet 4 passes over the top of the tunnel drainage pipe to tightly fix the upper surface of the tunnel drainage pipe and prevent the tunnel drainage pipe from floating. After the tunnel drainage pipe is placed, the first embedded block 2, the second embedded block 3, and the metal sheet 4 are used to tighten the tunnel drainage pipe by pulling one end of the metal sheet 4 in the second embedded block 3 to prevent it from floating during the concrete pouring process. Then, the end of the metal sheet 4 is fixed to fix the tight binding state of the tunnel drainage pipe and stabilize the positioning of the tunnel drainage pipe.

[0029] Furthermore, the metal sheet 4 is fixedly connected to the first embedded block 2 by bolts, and the connection end between the metal sheet 4 and the first embedded block 2 is embedded in the tunnel lining concrete along with the first embedded block 2 to complete the fixation of one end of the metal sheet 4.

[0030] Furthermore, the second embedded block 3 has a first through hole 5 and a second through hole 6 through which the metal sheet 4 passes.

[0031] Furthermore, after passing through the first perforation 5 from top to bottom, the metal sheet 4 continues to pass through the second perforation 6 from bottom to top, and the metal sheet 4 extending upward from the second perforation 6 is fastened to the bottom concrete below the tunnel drainage pipe by screws.

[0032] Specifically, the metal sheet 4 passes through the first perforation 5 from top to bottom and then continues to pass through the second perforation 6 from bottom to top to connect the metal sheet 4 to the second embedded block 3 and embed it together with the second embedded block 3 in the tunnel lining concrete. When laying the tunnel drainage pipe, the metal sheet 4 is loosened to allow the tunnel drainage pipe to pass through. Then, the metal sheet 4 protruding from the second perforation 6 is tightened and then fixed to the bottom concrete below the tunnel drainage pipe with screws.

[0033] Furthermore, an arc-shaped protrusion 7 is provided on the lower surface of the second embedded block 3 at the position between the first through hole 5 and the second through hole 6.

[0034] Furthermore, the metal sheet 4 covers the arc-shaped protrusion 7 as it passes between the first perforation 5 and the second perforation 6.

[0035] Specifically, during the process of passing the metal sheet 4 through the first perforation 5 and the second perforation 6, the metal sheet 4 slides on the arc-shaped protrusion 7, making it easier to pull the metal sheet 4 later and less likely to break it. After adjusting the metal sheet 4, the metal sheet 4 is fixed.

[0036] In summary, this device secures the two ends of the metal sheet of the tunnel drainage pipe by pre-embedding the first and second pre-embedding blocks in the tunnel lining concrete, making the metal sheet firmly fixed and not easy to fall off. The bottom support provides initial support for the tunnel drainage pipe, effectively preventing the tunnel drainage pipe from floating and shifting during the secondary lining concrete pouring.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
