Description

Technical Field

[0001] This utility model relates to a comprehensive utility tunnel, and more particularly to a cut-resistant sliding support for use in comprehensive utility tunnels or micro-utility tunnels. Background Technology

[0002] With the development of integrated utility tunnels, the forms of pipe supports within the tunnels have also diversified. Pipe supports are mainly divided into fixed supports and sliding supports, and their construction methods are mainly divided into steel structures and reinforced concrete structures. Currently, the commonly used sliding supports in utility tunnels generally employ curved steel supports. The upper part of the support is a steel sliding guide support, and the lower part is a concrete support foundation. Clamps are fastened to the pipe and fixed to the sliding guide support at the pipe's chest area using bolts. While this type of support has reasonable stress distribution and is relatively convenient to manufacture and construct, the bolts securing the clamps to the sliding guide support protrude from the pipe's outer wall, occupying some of the maintenance passage space. On the one hand, workers are at risk of being cut by the protruding fasteners during inspections; on the other hand, if pipes are arranged on both sides of the passage, the fasteners will occupy even more passage space, potentially causing inconvenience for personnel maintenance and pipe hoisting. Micro-utility tunnels are single-compartment micro-integrated utility tunnels used in historical and cultural districts. Due to the narrow space and difficult maintenance within the tunnel, it is even more crucial for pipe supports within the tunnel to avoid occupying passage space. Utility Model Content

[0003] This utility model provides a cut-resistant sliding support for integrated utility tunnels or micro-utility tunnels, solving the problem that the fixing parts of current pipe supports in tunnels can easily cut workers. The technical solution is as follows: A cut-resistant sliding support for integrated utility tunnels or micro-utility tunnels includes a pipe clamp, a pipe, a prefabricated support, a support pier, and rubber gaskets. The prefabricated support supports the pipe above and rests on the support pier below. The support pier is an integral structure with the base plate of the integrated utility tunnel. The pipe clamp is U-shaped, bypasses the pipe, and extends to both sides of the prefabricated support. Rubber gaskets are provided on the inner side of the pipe clamp and in the area where the prefabricated support fits against the pipe.

[0004] The finished support has an I-shaped cross-section, and the part that contacts the pipe 2 at the top has a rounded transition.

[0005] The pre-embedded steel plate is installed above the support pier, and the finished support is welded to the pre-embedded steel plate as a whole.

[0006] The rubber gasket includes a first rubber gasket and a second rubber gasket. The first rubber gasket is located inside the pipe clamp, and the second rubber gasket is located within the area where the finished support fits the pipe.

[0007] The two ends of the pipe clamp extend to both sides of the finished support. Bolt assemblies are provided on both sides of the finished support to lock the two ends of the pipe clamp to both sides of the finished support.

[0008] A first rubber gasket is provided below the pipe clamp, and the first rubber gasket passes through a hole drilled at the bolt of the bolt assembly.

[0009] The material of the support and pier is reinforced concrete, and the material of the embedded steel plate, finished support, pipe clamp and bolt assembly is steel.

[0010] The bolt assembly is installed from the outside in, and the nut is installed inside the finished support.

[0011] The anti-cut sliding support piers applied to integrated utility tunnels or micro-utility tunnels reduce the space occupied in the passageway by changing the support pier type and bolt fixing direction, preventing workers from being easily cut by protruding fasteners during inspections, ensuring the safety of maintenance personnel and facilitating pipeline transportation.

Detailed Implementation

[0013] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0014] The following embodiments are merely examples to clearly illustrate the present invention and are not intended to limit the implementation of the present invention. Those skilled in the art will recognize that other variations or modifications can be made based on the following description, and these obvious variations or modifications arising from the spirit of the present invention are still within the protection scope of the present invention.

[0015] like Figures 1 to 4As shown, the anti-cut sliding support for integrated utility tunnels or micro-utility tunnels includes a pipe clamp 1, a pipe 2, a prefabricated support 5, a support pier 6, and rubber gaskets. The prefabricated support 5 supports the pipe 2 above and is placed on the support pier 6 below. The support pier 6 is an integral structure with the base plate of the integrated utility tunnel. The pipe clamp 1 is U-shaped, bypassing the pipe 2 and extending to both sides of the prefabricated support 5. Rubber gaskets are provided on the inner side of the pipe clamp 1 and in the area where the prefabricated support 5 is in contact with the pipe 2.

[0016] The rubber gasket includes a first rubber gasket 7 and a second rubber gasket 8. The first rubber gasket 7 is located inside the pipe clamp 1, and the second rubber gasket 8 is located within the area of ​​the finished support 5 that fits against the pipe 2.

[0017] The two ends of the pipe clamp 1 extend to both sides of the finished support 5. Bolt assemblies 4 are provided on both sides of the finished support 5, and the two ends of the pipe clamp 1 are locked to the two sides of the finished support 5 by the bolt assemblies 4. The first rubber gasket 7 is provided below the pipe clamp 1, and after the two ends of the pipe clamp 1 are locked to the two sides of the finished support 5 by the bolt assemblies 4, a hole is drilled through it. Furthermore, the bolt assemblies 4 are installed from the outside to the inside, and the nuts are installed on the inside of the finished support 5.

[0018] The finished support 5 and the pipe clamp 1 are connected and fastened in a 180° direction. The bolt assembly 4 is installed from the outside to the inside, which can reduce the space occupied in the maintenance passage. The pipe clamp 1 is less likely to cut workers.

[0019] The finished support 5 has an I-shaped cross-section, and the part that contacts the pipe 2 at the top is made of arc transition. It is integrally formed and has good stability. A second rubber gasket 8 is provided on the top of the finished support 5, which is located in the area where the finished support 5 is in contact with the pipe 2.

[0020] Furthermore, the embedded steel plate 3 is installed above the support pier 6, and the finished support 5 is welded to the embedded steel plate 3 as a whole. The support pier 6 is made of reinforced concrete, while the embedded steel plate 3, the finished support 5, the pipe clamp 1, and the bolt assembly 4 are made of steel, which requires machining.

[0021] This utility model has the following advantages: (1) The cross-section of the finished support adopts an I-shaped structure, and the part in contact with the pipe adopts a rounded transition method. It is integrally formed and has good stability.

[0022] (2) The finished support and pipe clamp are connected and fastened in the 180° direction, which can reduce the space occupied in the maintenance passage and the pipe clamp is less likely to cut the staff.
