Abstract
Description
Technical Field
[0001] The utility model relates to a pipe gallery structure, in particular to a high-pressure circular pipe gallery structure, and belongs to the technical field of civil engineering, especially underground pipe gallery construction. Background Art
[0002] Underground pipe corridors are used to house cables and pipelines below the ground, facilitating their layout and maintenance. Underground pipe corridors are suitable for a variety of complex geological conditions and are subject to heavy loads, making their load-bearing capacity particularly important. Traditional reinforced concrete pipe corridor structures are deficient in terms of pressure bearing capacity and waterproofing, especially under high pressure and complex geological conditions. The wall thickness and reinforcement are very large, resulting in high construction costs and difficulty for underground pipe corridors. Therefore, it is necessary to design an underground pipe corridor that, by optimizing the structural form, maintains or even improves the pipe corridor's pressure bearing capacity without increasing the pipe wall thickness and reinforcement specifications. Utility Model Content
[0003] The purpose of this utility model is to solve the above shortcomings and provide a high-pressure circular pipe gallery structure, optimize the structural design, control the wall thickness, ensure the pressure-bearing capacity, and reduce the construction cushion area.
[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:
[0005] A high-pressure circular pipe gallery structure includes a pipe gallery main body, wherein a load-bearing outer lining is provided on the outside of the pipe gallery main body; a load-bearing portion is provided on the top of the load-bearing outer lining; connecting through holes are provided on the front and rear end faces of the load-bearing outer lining; and an inner partition wall is provided inside the pipe gallery main body.
[0006] Furthermore, the main body of the pipe gallery is a circular reinforced concrete pipe gallery; the load-bearing outer lining is coated on the outside of the pipe gallery main body; the load-bearing outer lining and the pipe gallery main body are coaxially arranged.
[0007] Furthermore, the load-bearing outer lining has a first upper plane and a first lower plane; the first upper plane and the first lower plane are connected by a transition arc surface; there are four connecting through holes, which are evenly distributed at the four top corners of the load-bearing outer lining.
[0008] Furthermore, the load-bearing outer lining has a second upper plane and a second lower plane; the length of the second upper plane is smaller than the length of the second lower plane; the second upper plane and the second lower plane are connected by a transition arc surface.
[0009] Furthermore, there are three connecting through holes, which are evenly distributed at three corners of the load-bearing outer lining.
[0010] Furthermore, a through groove is provided on the top of the load-bearing outer lining; the through groove is parallel to the axial direction of the pipe gallery body; and the load-bearing part is arranged in the through groove.
[0011] Furthermore, the load-bearing part is a UHPC ultra-high performance concrete rectangular steel pipe; the load-bearing part is arranged in the through groove through a fixed bracket; and the upper part of the through groove is open.
[0012] Furthermore, limiting grooves are provided on both sides of the through groove; the limiting grooves are communicated with the through groove; limiting protrusions are provided on both sides of the load-bearing part; and the limiting protrusions are snap-fitted into the limiting grooves.
[0013] This utility model has the following beneficial effects: By adopting a specially designed load-bearing outer lining, combined with the circular pipe gallery structure, the overall rigidity and compressive resistance of the pipe gallery can be improved in terms of structural form. Compared with traditional pipe gallery structures, this design adopts a multi-layered arched curved surface structure for load bearing, effectively distributing the upper load. Under the premise of the same wall thickness and reinforcement, its load-bearing capacity is significantly better than that of traditional pipe gallery forms. At the same time, the load-bearing outer lining is equipped with a load-bearing portion, which is made of ultra-high-performance rectangular steel pipe and arranged along the length of the load-bearing outer lining, which can further increase the rigidity of the load-bearing outer lining and prevent it from breaking.

[0030] In this embodiment, the load-bearing outer lining 2 features upper and lower planes of equal length. Four connecting holes 3 are used as the connection points between the front and rear pipe galleries. Because the first upper plane 2-1 and the first lower plane 2-2 of the load-bearing outer lining 2 are connected by a transitional curved surface 2-3, the upper load is effectively distributed.
[0031] In the drawings of this embodiment, the through slot 5 is not shown because it is covered by the upper cover.

[0034] Furthermore, the load-bearing outer lining 2 has a second upper plane 2-4 and a second lower plane 2-5; the length of the second upper plane 2-4 is smaller than the length of the second lower plane 2-5; the second upper plane 2-4 and the second lower plane 2-5 are connected by a transition arc surface 2-3.
[0035] Furthermore, there are three connecting through holes 3 , which are evenly distributed at the three corners of the load-bearing outer lining 2 .
