These concentrated pipeline corridors are called pipe galleries. Pipe galleries are generally open-air and overhead, supported by concrete or steel supports to form corridor-like passages. A clear height of more than 4.5 meters is generally left under the pipe gallery to ensure that fire trucks can pass smoothly when there is a fire road under the pipe gallery.

[0003] The patent with application number 201520390474.1 discloses an integrated modular pipe gallery system, wherein each pipe gallery submodule includes a pipe gallery, a support frame and a support frame, wherein the support frame is fixed on the support frame, and the support frame includes a horizontal pipe support and a vertical pipe support, wherein the horizontal pipe support and the vertical pipe support are vertically fixed to each other to form a multi-layer frame structure, wherein each layer of the frame structure forms a pipe gallery for placing pipes, and a plurality of rows of positioning rings are provided in the pipe gallery.

[0004] The problems with the patent solution with application number 201520390474.1 are: 1. There are still many high-altitude operations in the installation of the pipeline corridor system; 2. It is unclear how to firmly limit the pipeline on the support frame so that the pipeline will not fall during the lifting process. Utility Model Content

[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] Engineering construction company B undertook a new construction project P. The length of the pipeline corridor connecting the periphery of the device is 500 meters. The pipeline corridor is divided into 3 layers, with the lowest layer being 6 meters high. 20 pipes are laid above the pipeline corridor, with a total length of approximately 10,000 meters. Company B used a pipeline corridor system that can be constructed in a modular manner to construct this project.

[0024] like Figures 1 to 6 As shown, a pipe gallery system capable of modular construction includes multiple pipe gallery sub-modules, and the pipe gallery sub-module includes a pipe gallery frame 1, the pipe gallery frame 1 is fixedly connected to a pipe unit 2 by a fixing device, and a pipe gallery column 3 is fixedly connected to the bottom of the pipe gallery frame 1; the pipe units 2 between adjacent pipe gallery sub-modules are welded, and the pipe gallery columns 3 include column units connected by bolts.

[0025] The pipe gallery frame 1 includes a plurality of horizontal frames 101 and vertical frames 102 , and intervals are provided between adjacent horizontal frames 101 .

[0026] like Figure 5 and Figure 6 As shown, the fixing device includes a pipe support 4 and a fixing member 5. The pipe support 4 is fixedly connected to the pipe gallery frame 1 by bolts. The pipe support 4 can hold the pipe unit 2 tightly to limit the pipe unit 2; the fixing member 5 includes two bolt and nut assemblies 501 and two teardrop-shaped clamps 502. The bolt and nut assemblies 501 are fixedly connected to the cross frame 101 and are used to limit the left and right sides of the pipe unit 2. The teardrop-shaped clamps 502 are fixedly connected to the pipe unit 2. The teardrop-shaped clamps 502 are clamped on both sides of the cross frame 101 and are used to limit the front and back sides of the pipe unit 2. During the lifting process, the pipe unit 2 has a very small upward and downward movement range, so there is no need to limit its upward and downward directions.

[0027] Some of the pipe units 2 in the pipe gallery frame 1 need to be connected using pipe supports, while some of the pipe units 2 are larger in size and do not need to be connected using pipe supports. However, both types of pipe units 2 need to be limited to prevent the pipe units 2 from moving during hoisting. By providing pipe supports 4 and fixings 5, both types of pipe units 2 can be firmly limited and will not fall during the hoisting process. The fixings 5 ​​have a lower cost and are suitable for limiting the larger pipe units 2 that do not need to be connected using pipe supports.

[0028] like Figure 3 and Figure 4 As shown, the two ends of the pipe unit 2 are not aligned with the cross frame 101 in the up-down direction, so that there is enough space when the pipes are welded.

[0029] The construction method of the pipe gallery system capable of modular construction includes the following steps:

[0030] S1. Process the pipe gallery frame 1, pipe unit 2, column unit, pipe support 4 and fixing piece 5 in the factory, and use the pipe support 4 and fixing piece 5 to fix the pipe unit 2 at the designated position of the pipe gallery frame 1 to form a first assembly; if the pipe unit 2 needs to be painted or needs to be covered with a heat-insulating or cold-insulating sleeve, the construction is carried out in the factory; during the construction, a distance needs to be left at the welding points at both ends of the pipe unit 2 to prevent damage to the paint, heat-insulating sleeve or cold-insulating sleeve during welding; the operations in this step are all completed on the ground, which is safer;

[0031] S2, loading the first assembly and the column unit onto a truck, and transporting them to the construction site for unloading; the pipe support 4 and the fixing member 5 can ensure that the pipe unit 2 will not fall during the loading and unloading of the first assembly;

[0032] S3, start installation, first install the column unit into the corridor column 3 and stand it up and fix it, then hoist the first assembly onto the corridor column 3, and fix the corridor column 3 to the first assembly; weld the pipe units 2 of adjacent corridor sub-modules; after welding the pipe units 2 of adjacent corridor sub-modules, spray paint or cover the reserved distance with insulation or cold-keeping sleeves; complete the construction in two times, avoiding damage to the paint, insulation sleeve or cold-keeping sleeve during welding, and most of the work is completed on the ground, reducing the time of high-altitude operations and ensuring the construction quality.

[0033] A total of 100 construction workers were involved in the construction, including 20 high-altitude workers and 80 factory and ground prefabrication and service personnel. The construction was carried out under a normal working environment, and it took a total of 100 days to complete the project and deliver it to the construction unit. The costs of labor, materials, machinery, etc. were 22 million yuan. This construction method reduces the number of high-altitude workers by 75%, and the duration of high-altitude work is only about 25 days, a reduction of 83.3%. The safety hazards and accident rate are reduced by more than 85%. The cost of hiring lifting vehicles is reduced by 83.3%, the project investment cost is reduced by 26.7%, the construction period is shortened by 44.4%, the work efficiency is high, and there are few factors affecting the construction quality. It has an absolute competitive advantage in the industry.

[0034] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
