Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of integrated pipe corridors, in particular to a pipe corridor transition structure that crosses obstacles. Background Art
[0002] The integrated pipe gallery is a comprehensive pipeline corridor structure buried underground. Therefore, the design of the pipe gallery is bound to be affected by the underground space, especially when building underground integrated pipe galleries in built-up areas. Subways, drainage culverts, rivers, etc. are all important factors affecting it. Therefore, the pipe gallery generally adopts the method of crossing over and under to avoid underground buildings. When the overburden of the underground building meets the height requirements of the pipe gallery, the overburden can be passed. However, when the depth of the overburden on the top of the underground building cannot meet the requirements, the underpass method must be adopted. However, the underpass of the pipe gallery will bring many disadvantages, such as increasing the difficulty of construction, increasing the depth of the foundation pit and the support of the pipe gallery, or using the jacking process to cross obstacles, resulting in a substantial increase in investment.
[0003] Therefore, how to avoid the pipeline corridor passing under underground buildings and reduce the construction difficulty and construction cost has become a technical problem that technical personnel in this field urgently need to solve. Utility Model Content
[0004] In view of the above-mentioned defects of the prior art, the utility model provides a pipe gallery transition structure that crosses over obstacles, the purpose of which is to cross over and pass through underground buildings, thereby reducing construction difficulty and construction cost.
[0005] In order to achieve the above technical purpose, the utility model provides a pipe gallery transition structure that crosses an obstacle, comprising two standard sections, the opposite ends of the two standard sections are respectively connected to a deformation section, the two deformation sections are connected through a transition section, and structural seams are respectively provided between the adjacent standard sections and the deformation sections, and between the deformation sections and the transition sections;
[0006] The width of the transition section is greater than the width of the standard section, and the height of the transition section is less than the height of the standard section.
[0007] Preferably, multi-layer support arm brackets are respectively provided on the side walls of the transition section, the deformation section and the standard section; the length of the support arm bracket of the transition section is greater than the length of the support arm bracket of the standard section.
[0008] Beneficial effects of the utility model:
[0009] Due to the structural design, when encountering underground buildings such as subways, drainage culverts, and rivers that conflict with the elevation of the pipeline corridor, and the soil cover on the underground buildings is insufficient for the standard section of the pipeline corridor to pass over, the deformation section and the transition section can cross over the underground buildings, which not only reduces the burial depth of the pipeline corridor construction and reduces construction risks, but also reduces the construction difficulty and construction cost of the pipeline corridor.

[0015] The concept, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings to fully understand the purpose, characteristics and effects of the present invention.
[0016] Example:
[0017] like Figure 1-Figure 4 As shown, the corridor transition structure that crosses the obstacle includes two standard sections 1, and the opposite ends of the two standard sections 1 are respectively connected to deformation sections 2, and the two deformation sections 2 are connected by a transition section 3. Structural seams 4 are respectively arranged between adjacent standard sections 1 and deformation sections 2, and between deformation sections 2 and transition sections 3.
[0018] The width of the transition section 3 is greater than that of the standard section 1, and the height is less than that of the standard section 1.
[0019] The main innovation of the utility model is that when the top soil cover depth of the underground building 7 cannot meet the requirement of the standard section 1 to cross over, the deformation section 2 and the transition section 3 can cooperate to cross over the underground building 7 .
[0020] Specifically, multi-layer brackets 5 are respectively arranged on the side walls of the standard section 1, the deformation section 2, and the transition section 3, for laying the pipe gallery pipelines 6. Furthermore, multi-layer brackets 5 are respectively arranged on the side walls of the transition section 3, the deformation section 2, and the standard section 1; the length of the brackets of the transition section 3 is greater than the length of the brackets of the standard section 1, and the number of layers of the brackets 5 of the transition section 3 is less than the number of layers of the brackets 5 of the standard section 1, which can also meet the number and requirements of the arrangement of the pipe gallery pipelines 6 in the standard section 1, and the number and length of the brackets 5 in the deformation section 2 are determined according to the requirements of the pipe gallery pipelines 6 from the standard section 1 to the transition section 3.
[0021] A safety distance must be left between the support arm brackets 5 of the standard section 1, the deformation section 2, and the transition section 3, or between the support arm brackets 5 and the side walls of the standard section 1, the deformation section 2, and the transition section 3 to ensure the installation and routine maintenance of the corridor pipelines 6.
[0022] The working principle and construction process of this utility model:
[0023] The pipelines 6 of the pipe gallery are first arranged in the standard section 1 of the conventional pipe gallery. When encountering obstacles that conflict with their elevations, such as subways, drainage culverts, and rivers, and the upper cover is insufficient for the standard section 1 to cross over, the deformation section 2 and transition section 3 set at this time can cross over the obstacles. By compressing the cross-sectional height of the transition section 3 of the pipe gallery, the requirements of the deformation section 2 and transition section 3 of the pipe gallery crossing the obstacles are met, and the number of pipelines 6 of the pipe gallery is not affected.
[0024] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
