Description

Technical Field

[0001] This utility model relates to the field of tunnel construction auxiliary devices, specifically a drainage structure for tunnel invert arches. Background Technology

[0002] The drainage structure for the tunnel invert is a crucial but often overlooked component in tunnel engineering. Its core function is to collect and effectively drain groundwater beneath the invert (tunnel foundation), preventing water pressure buildup and ensuring the long-term stability and safety of the tunnel structure.

[0003] Currently, in the process of tunnel construction, how to quickly and efficiently deploy drainage structures is the key to improving tunnel construction efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a drainage structure for tunnel invert arches, so as to achieve the goal of quickly deploying an efficient drainage structure during tunnel construction.

[0005] To achieve the above objectives, the present invention employs the following technical means:

[0006] A drainage structure for a tunnel invert includes a water collection pipe arranged inside the invert, a water gathering pipe connected to the outer arc side of the water collection pipe, and water outlet pipes connected to both ends of the water collection pipe. The water outlet pipes extend from the inner wall of the invert, a water collection sleeve is installed on the bottom inner wall of the invert, the water outlet pipes are connected to the inner cavity of the water collection sleeve, and a drain pipe is connected to the bottom end of the water collection sleeve, extending from the bottom of the invert.

[0007] Preferably, the water collection pipe is arranged along the arc surface of the inverted arch.

[0008] Furthermore, the water collection jacket is a soft structure with an open top surface.

[0009] Furthermore, an arc-shaped water guide plate is constructed on the inner arc surface of the inverted arch, with both ends of the arc-shaped water guide plate extending into the water collection sleeve.

[0010] Furthermore, the top surface of the arc-shaped water guide plate is connected to the inner arc wall of the inverted arch by a connecting rod, which is located on the top arc surface of the arc-shaped water guide plate.

[0011] This utility model has the following beneficial effects during use:

[0012] During the layout, it is only necessary to pre-embed a water collection pipe and a water gathering pipe on the top surface of the invert arch, connecting the water gathering pipe to the return water pipe. Then, a water outlet pipe connected to the water collection pipe is installed below the side wall of the invert arch. By setting up a simple water collection sleeve, sealing the bottom and sides of the sleeve, groundwater can be introduced into the water collection pipe through the water collection pipe. The groundwater in the water collection pipe is then collected into the water collection sleeve through the water outlet pipe, and finally discharged from the water collection sleeve through the drain pipe. The entire system is easy to arrange and has good drainage effect, which can greatly improve the efficiency of tunnel construction. Attached Figure Description

[0021] Please refer to Figure 1 As shown, a drainage structure for a tunnel invert includes a water collection pipe 2 arranged inside the invert 1. The outer arc side of the water collection pipe 2 is connected to a water collection pipe 3. Both ends of the water collection pipe 2 are connected to water outlet pipes 4. The water outlet pipes 4 extend from the inner wall of the invert 1. A water collection sleeve 5 is installed on the bottom inner wall of the invert 1. The water outlet pipe 4 is connected to the inner cavity of the water collection sleeve 5. The bottom end of the water collection sleeve 5 is connected to a drain pipe 6. The drain pipe 6 extends from the bottom of the invert 1.

[0022] In this way, during the layout, it is only necessary to pre-embed a water collection pipe 2 and a water gathering pipe 3 on the top surface of the invert arch 1, connecting the water gathering pipe 3 to the return water pipe. Then, a water outlet pipe 4 connected to the water collection pipe 2 is set below the side wall of the invert arch 1. By setting up a simple water collection sleeve 5 and sealing its bottom and sides, groundwater can be introduced into the water collection pipe 2 through the water gathering pipe 3. Then, the groundwater in the water collection pipe 2 is collected into the water collection sleeve 5 through the water outlet pipe 4, and then discharged from the water collection sleeve 5 through the drain pipe 6. The entire system is easy to arrange and has a good drainage effect, which can greatly improve the efficiency of tunnel construction.

[0023] Furthermore, the water collection pipe 3 is arranged along the arc surface of the inverted arch 1.

[0024] Furthermore, this ensures that groundwater is fully collected into the water collection pipe 2, minimizing the accumulation of groundwater at the top of the invert arch 1 and preventing potential safety hazards.

[0025] Furthermore, the water collection sleeve 5 is a soft structure with an open top surface.

[0026] In this embodiment, the water collection sleeve 5 can be made of waterproof cloth, which seals the bottom and sides of the waterproof cloth. This allows for convenient and quick installation of the water collection sleeve 5 inside the invert arch 1, and also makes it easy to remove the water collection sleeve 5 after construction is completed.

[0027] Furthermore, an arc-shaped water guide plate 7 is constructed on the inner arc surface of the inverted arch 1, with both ends of the arc-shaped water guide plate 7 extending into the water collection sleeve 5.

[0028] In this way, by using the arc-shaped water guide plate 7, some of the groundwater dripping from the top surface of the invert arch 1 can drip onto the arc-shaped water guide plate 7, and then the dripping groundwater can flow along the arc-shaped water guide plate 7 and flow into the water collection sleeve 5 for collection, thereby improving the effect of the drainage structure.

[0029] In order to improve the installation stability and ease of installation of the arc-shaped water guide plate 7, the top surface of the arc-shaped water guide plate 7 is connected to the inner arc wall of the arch 1 by a connecting rod 8, which is located on the top arc surface of the arc-shaped water guide plate 7.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
