Description

Technical Field

[0001] The utility model relates to a bracket device for a drainage pipeline of a water-rich tunnel, belonging to the technical field of tunnel construction. Background Art

[0002] In water-rich tunnels, in order to ensure the effective pumping and drainage of water in the tunnel, multiple steel pipes need to be installed on the side walls of the tunnel according to the amount of water. When the pipe is filled with water, it is heavy. In order to support the drainage pipe, it is usually necessary to drive steel bars into the primary support or secondary lining of the tunnel to form a supporting structure for the drainage pipe. However, when multiple drainage pipes exist at the same time, it is necessary to install steel bars and pipes in layers during the installation of the pipes. Due to the poor stability of the steel bar support, it is easy to collide with the installed pipes in the lower layer during the subsequent pipeline installation process, causing certain safety risks. In addition, due to the layered fixing method of steel bars, the straightness of multiple layers of steel bars needs to be controlled, and the construction efficiency is low. In addition, the drainage pipeline is fixed in this way, the aesthetics is poor, and the standardized construction level is low. Utility Model Content

[0005] In the utility model, the upper part of the crossbar of the upper frame is the installation position of the pipeline, and the triangular block on the crossbar is used to limit the horizontal position of the pipeline on the crossbar. The bottom support frame is supported on the tunnel floor, which can effectively support the upper frame, improve the force bearing capacity of the entire pipeline support, and the structural design of the bottom support frame can also be used for pipeline layout, which can make full use of the upper space of the tunnel drainage system and improve the pipeline layout capacity. The bottom support frame is straddled above the drainage system, which effectively protects the ditch cover of the drainage system and avoids vehicles from rolling over the ditch.

[0006] Furthermore, in order to adapt to the curved surface of the tunnel side wall, the upper frame includes two sections separated from each other, and both sections are fixed to the tunnel side wall by expansion bolts.

Compared with the conventional steel support, the loosening, deformation, and leakage of the pipeline interface caused by the instability of the support system are reduced, and the utility model is simpler to install and has high construction efficiency compared with the conventional steel support. The setting of the bottom support frame in the utility model can not only improve the overall force bearing capacity of the pipe support and improve the overall stability of the support, but also its structural design can also be used for pipeline laying, which can make full use of the upper space of the tunnel drainage system and improve the pipeline laying capacity, and the bottom support frame is arranged across the drainage system, which effectively protects the ditch cover of the drainage system and avoids the rolling of the ditch by vehicles.

DETAILED DESCRIPTION

[0013] The present invention is further described below by way of non-limiting embodiments and in conjunction with the accompanying drawings:

[0014] As shown in the attached drawings, an integrated support device for drainage pipelines in a water-rich tunnel includes a plurality of pipe supports arranged at intervals along the longitudinal direction of the tunnel, and the pipe supports are made of angle steel. The pipe support includes a bottom support frame 1 and an upper frame 2. The upper frame 2 includes a vertically arranged vertical bar 2-1 and at least two horizontal bars 2-2 arranged up and down. The horizontal bar 2-2 is arranged horizontally, and one end of the horizontal bar 2-2 is welded to one side of the vertical bar 2-1. A triangular stopper 8 is fixed to the upper part of the outer end of each horizontal bar 2-2. The triangular stopper 8 can be made of angle steel and welded to the horizontal bar 2-2. The upper part of the horizontal bar 2-2 is the installation position of the pipeline. The triangular stopper 8 is used to horizontally limit the installed pipeline. The setting position of the triangular stopper 8 should be adapted to the specifications of the pipeline. The number of horizontal bars 2-2 can be determined according to the number of pipelines to be laid, and the spacing between the horizontal bars 2-2 should meet the pipeline installation requirements. Bolt holes are arranged on the vertical rod 2-1, and the upper frame 2 is fixed to the secondary lining 4 of the tunnel side wall by expansion bolts. The bottom support frame 1 is arranged at the lower end of the upper frame 2, and the bottom support frame 1 crosses the drainage system 6 of the tunnel and is supported on the tunnel floor 7. The bottom support frame 1 includes a vertical support 1-1 and two horizontal supports 1-2 arranged up and down, one end of each of the two horizontal supports 1-2 is welded to the vertical support 1-1, the other end of the horizontal support 1-2 located at the upper part of the bottom support frame 1 is fixedly connected to the bottom end of the upper frame 2, and the other end of the horizontal support 1-2 located at the lower part of the bottom support frame 1 is fixedly connected to the secondary lining 4 of the tunnel side wall by expansion bolts 3. The vertical support 1-1 of the bottom support frame 1 is supported on the tunnel floor 7, and the horizontal support 1-2 located at the lower part of the bottom support frame 1 is located above the drainage system 6. According to the pipeline layout requirements, drainage pipes can also be laid on the upper part of the cross brace 1-2 of the bottom support frame 1. In order to limit the pipes on the cross brace 1-2, a triangular stopper 8 is also provided on the upper part of the cross brace 1-2. In order to ensure the structural strength of the bottom support frame 1, the bottom support frame 1 can use thickened angle steel. In this embodiment, the bottom support frame 1 is made of No. 10 thickened angle steel, and the upper frame 2 is made of No. 10 angle steel. In order to ensure that the pipeline support is firmly connected to the side wall of the tunnel, it is preferred to drill holes on the vertical bars of the upper frame 1 corresponding to the positions of each cross bar 2-2 on the upper frame 2, and set an expansion bolt to connect with the side wall of the tunnel.

[0015] In order to adapt to the curved shape of the tunnel side wall, the upper frame 2 can also be divided into two sections, which are separated from each other, and both sections are fixed to the tunnel side wall by expansion bolts.

[0016] When installing the utility model, the pipe supports are arranged at intervals of 3m. According to the progress of tunnel construction, bolt holes matching expansion bolts are drilled on the side wall of the tunnel using drilling equipment. In order to improve the smoothness of the installation of the pipe supports, a wire is pulled or a laser is used for drilling guidance. After the drilling is completed, the pipe supports are fixed with expansion bolts. After the pipe supports are installed in place and effectively fixed, the pipes of different diameters are hoisted to the corresponding positions by manual labor in cooperation with the crane, and the pipe docking and assembly are completed manually.

[0017] The utility model can install various types of drainage pipelines by using the integrated bracket, the pipeline installation efficiency is high, the bracket device is stably stressed, and the safe operation of the drainage pipeline in the tunnel can be effectively guaranteed.

[0018] The other parts of this embodiment are all prior art and will not be described in detail here.
