Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipe gallery structures, in particular to a structure for increasing the lateral displacement resistance of a comprehensive pipe gallery. Background Art
[0002] At present, in the process of tunnel construction, in order to recycle and reuse the PC piles used for construction enclosure after the main structure of the tunnel is completed, the soil will be disturbed to varying degrees, thereby generating lateral displacement force on the main structure of the tunnel. As we all know, the current tunnel mainly adopts segmental structure, that is, the tunnel is composed of several tunnel segments along its longitudinal direction, and deformation joints are left between adjacent tunnel segments.
[0003] When the lateral displacement force acts on the main body of the corridor segment, the corridor segment can generally resist the lateral displacement force by its own weight. However, when the lateral displacement force acts on the deformation joints between the corridor segments, it often causes relative displacement between the corridor segments, resulting in reduced position accuracy of the main corridor structure and even damage to the main corridor structure. Summary of the invention
[0004] The purpose of the utility model is to provide a structure for increasing the lateral displacement resistance of a comprehensive pipe gallery in accordance with the above-mentioned deficiencies of the prior art, by adding reinforced concrete reinforcement rings at the deformation joints of the pipe gallery segments to resist the lateral displacement force exerted on the pipe gallery, thereby effectively ensuring the stability of the main body of the pipe gallery structure.

[0006] A structure for increasing the lateral displacement resistance of an integrated pipe gallery, comprising a plurality of pipe gallery segments, wherein the plurality of pipe gallery segments are combined to form a main pipe gallery structure, a pile foundation is arranged below the pipe gallery segment, and a C20 plain concrete cushion layer is arranged between the pile foundation and the pipe gallery segment, wherein the bottom of the pipe gallery segment is provided with steps extending to both sides, and a reinforced concrete reinforcement ring is arranged at the deformation joint position between adjacent pipe gallery segments, the reinforced concrete reinforcement ring is matched with the outer contour shape and size of the pipe gallery segment, covers the deformation joint position and extends to the part of the pipe gallery segment on both sides, and the bottom ends of the reinforced concrete reinforcement ring are supported on the steps arranged at the bottom of the pipe gallery segment.
[0007] A plurality of longitudinal steel bars are evenly arranged inside the reinforced concrete reinforcement ring, and the plurality of longitudinal steel bars are connected by transverse steel bars to form an integral structure.
[0008] The outer surface of the reinforced concrete reinforcement ring is flush with the outer surface of the step.
[0009] Anchor bars are reserved on the outer surface of the pipe gallery segment, and the anchor bars are anchored in the reinforced concrete reinforcement ring.
[0010] The reinforced concrete reinforcement ring covers the same area of the pipe gallery segments on both sides.
[0011] The utility model has the advantages of ensuring the stability and safety of the main structure of the pipe gallery, avoiding damage to the main structure of the pipe gallery during the process of pulling out the PC pipe piles, and ensuring the quality of the project; the structure is simple and reasonable, the construction is convenient, and it is suitable for promotion.

[0015] The following is a further detailed description of the features of the present invention and other related features through embodiments in conjunction with the accompanying drawings to facilitate understanding by technicians in the same industry:
[0016] like Figure 1-3 As shown in the figure, marks 1-7 respectively represent: pipeline corridor segment 1, reinforced concrete reinforcement ring 2, deformation joint 3, C20 plain concrete cushion layer 4, pile foundation 5, longitudinal steel bars 6, and transverse steel bars 7.
[0017] Example: Figures 1 to 3 As shown, in this embodiment, the structure for enhancing the lateral displacement resistance of the integrated pipe gallery is arranged at the deformation joint 3 between adjacent pipe gallery segments 1, which is used to enhance the stability of the pipe gallery here, especially to resist the lateral displacement force caused by extrusion during the process of pulling out the PC pipe piles, so as to ensure the quality of the project. In this embodiment, the pipe gallery segment 1 is supported on the pile foundation 5 below, and a C20 plain concrete cushion layer 4 is arranged between the pile foundation 5 and the pipe gallery segment 1.
[0018] Specifically, combined Figures 1 to 3 As shown, steps extending outward on both sides are provided at the bottom of the pipe gallery segment 1. A reinforced concrete reinforcing ring 2 is provided at the position of the deformation joint 3 of the adjacent pipe gallery segment 1, and the reinforced concrete reinforcing ring 2 covers the position of the deformation joint 3 and partially extends to the pipe gallery segments 1 on both sides to ensure that the reinforced concrete reinforcing ring 2 can completely cover the weak position of the pipe gallery segment 1.
[0019] In this embodiment, if Figure 2As shown, the inner contour shape and size of the reinforced concrete reinforcing ring 2 match the outer contour shape and size of the pipe gallery segment 1, so that the reinforced concrete reinforcing ring 2 can be completely fitted and fixed on the periphery of the pipe gallery segment 1, and the bottoms of both sides of the reinforced concrete reinforcing ring 2 are supported on the steps extending to the outside of the pipe gallery segment 1 on both sides. At this time, when the deformation joint 3 between adjacent pipe gallery segments 1 is subjected to lateral displacement force, the reinforced concrete reinforcing ring 2 resists the force, thereby enhancing the structural performance here.
[0020] In this embodiment, if Figure 3 As shown, in order to improve the resistance of the reinforced concrete reinforcement ring 2, a number of longitudinal steel bars 6 are evenly arranged in the cross section of the reinforced concrete reinforcement ring 2, and the plurality of longitudinal steel bars 6 are connected into an integral structure by binding or welding through transverse steel bars 7, thereby improving the structural bearing performance of the reinforced concrete reinforcement ring 2 itself, and further improving the resistance effect of the reinforced concrete reinforcement ring 2.
[0021] In the specific implementation of this embodiment: the outer surface of the reinforced concrete reinforcing ring 2 is flush with the outer surface of the step set on the pipe gallery segment 1, ensuring the structural integrity and fit between the two. At the same time, the reinforced concrete reinforcing ring 2 covers the same area of the pipe gallery segments 1 on both sides, so as to ensure that when the reinforced concrete reinforcing ring 2 is subjected to force, the force can be symmetrically and effectively distributed to the pipe gallery segments 1 on both sides, ensuring stable force.
[0022] In order to further increase the integrity between the tunnel segment 1 and the reinforced concrete reinforcement ring 2, during the prefabrication or construction of the tunnel segment 1, anchor bars extending outward are reserved on its outer surface. The anchor bars can be directly anchored into the reinforced concrete reinforcement ring 2, or they can be connected with the longitudinal steel bars 6 or transverse steel bars 7 in the reinforced concrete reinforcement ring 2 to form an integral structure and buried during the pouring.
[0023] Although the above embodiments have described the concepts and embodiments of the purpose of the utility model in detail with reference to the accompanying drawings, ordinary technicians in this field can recognize that various improvements and modifications can still be made to the utility model without departing from the scope of the claims, so they are not described one by one here.
