Description

Technical Field

[0001] The present invention belongs to the field of underground structure engineering, specifically relates to the field of integrated pipe gallery, and in particular to an anti-liquefaction device and method for integrated pipe gallery joints. Background Art

[0002] When an earthquake occurs, the underground structure will interact dynamically with the surrounding soil due to the constraints of the soil. The form of the interaction is related to the nature of the soil layer. When the earthquake wave arrives, the liquefied soil layer at the joint will change in nature, causing the structure to move and deform, resulting in the formation of liquefied strata in part of the soil, which will cause the structure to float. When the soil layer properties change within the joint range of the pipeline corridor, it will have an adverse effect on the joint of the structure, and the displacement caused by earthquake liquefaction will damage the pipeline corridor structure.

[0003] At present, due to the low stiffness of the joints of the corridor structure, the joints are a weak link in the seismic design of the corridor structure.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] Example As mentioned in the background technology, currently, due to the low stiffness of the joints of the corridor structure, the joints are a weak link in the seismic design of the corridor structure. Due to the low stiffness of the joints, the integrity of the corridors at both ends is poor. When an earthquake liquefaction causes flotation, the joints of the corridor structure are easily deformed, causing the liquefaction of the stratum to cause serious damage to the corridor structure.

[0036] In order to solve the above problems, the present embodiment provides an anti-liquefaction device for an integrated pipeline corridor joint. The anti-liquefaction device can effectively improve the joint stiffness and the integrity of the pipeline corridor structure. The anti-liquefaction device connects the pipeline corridors at both ends of the joint. When buoyancy caused by earthquake liquefaction occurs, it can enhance the integrity of the structure and reduce the damage of the pipeline corridor structure to the liquefied formation. like Figure 1 As shown, this embodiment provides an anti-liquefaction device for an integrated pipe gallery joint, which is applied to an underground pipe gallery and is specifically arranged at the connection between two pipe galleries; the specific structure and connection relationship are as follows: The anti-liquefaction device for the joint of the integrated pipe gallery comprises a fixed steel frame 1, a replaceable shear-resistant connecting steel beam 2, and a fixed support 3. The replaceable shear-resistant connecting steel beam 2 is arranged on the fixed steel frame 1, and the fixed support 3 connects and fixes the fixed steel frame 1 to the inner wall of the pipe gallery 8; The fixed steel frame 1 includes a steel frame column 1-1, a first steel frame beam 1-2; a second steel frame beam 1-3, and a placement groove 1-4; the steel frame column 1-1 and the first steel frame beam 1-2 are welded to form a square frame (i.e., a frame body) connected to the inner wall of the pipe gallery, and the second steel frame beam 1-3 is installed at the same time and connected to the steel frame column 1-1. The placement groove 1-4 is formed by the composed frame to ensure that the use of the pipe gallery is not restricted.

[0037] like Figure 7 As shown, the space formed by the steel frame column 1-1, the first steel frame beam 1-2; and the second steel frame beam 1-3 includes a placement groove 1-4. The steel frame column 1-1 and the first steel frame beam 1-2 are welded to form a square frame that is close to the inner wall of the pipe gallery 8, ensuring the integrity of the structure. The steel frame column 1-1, the first steel frame beam 1-2, and the second steel frame beam 1-3 form a cavity for placing channel pipelines. The first steel frame beam 1-2; the second steel frame beam 1-3 form a placement groove 1-4 for placing a shear device; as shown Figure 5 As shown, the second steel frame cross beam 1-3 is connected to the steel frame column 1-1 through a connecting plate 7, and the connecting plate 7 adopts an L-shaped steel plate structure to improve the shear resistance; Figure 3 As shown, there is no second steel frame cross beam 1-3 on the other side, and the replaceable shear-resistant connecting steel beam 2 is fixed by the positioning support 4. The different configurations on both sides can reduce the influence of the replaceable shear-resistant connecting steel beam on the deformation joint. Figure 6 and Figure 8 As shown, in this embodiment, the steel frame vertical column 1-1 is engraved with scale lines, and combined with the spirit level 2-2, the settlement and deformation of the pipeline corridor can be effectively surveyed. The replaceable shear-resistant connecting steel beam 2 includes a steel beam body 2-1 and a spirit level 2-2. The spirit level 2-2 is embedded in the middle part of the steel beam body 2-1, which can effectively monitor the relative inclination of the two sides of the pipeline corridor 8 and the deformation of the steel beam body 2-1. One side of the steel beam body 2-1 is connected to the first steel frame cross beam 1-2 through a positioning support 4, and the other side is fixed in the placement groove 1-4 through a set of limit devices 5, which can release the longitudinal expansion and contraction deformation of the pipeline corridor.

[0038] In this embodiment, the level meter 2-2 preferably adopts an electronic level meter to monitor the inclination direction and angle of the corridor 8. When uneven settlement occurs in the corridor 8, the longitudinal displacement of the corridor 8 can be detected to monitor and warn of structural damage to the corridor 8.

[0039] In this embodiment, the fixed steel frame 1 is provided with a reserved pipeline channel, and the position of the limiting device 5 can be changed according to the position of the pipeline inside the pipe gallery 8. The limiting device 5 and bolts are placed on the fixed steel frame 1 to eliminate the influence of the limiting device 5 on the pipeline.

[0040] like Figure 4 and Fig. 9 as well as Fig.12 As shown, in this embodiment, the fixed support 3 includes an extended section and an overlapped section. Specifically, the overlapped section overlaps with the outer end of the first steel frame beam 1-2, and the bolt holes thereon overlap, and the fixed support 3 is connected to the fixed steel frame 1 and the pipe gallery 8 by bolts. The extended section is connected to the inner wall of the adjacent pipe gallery 8 by bolts, and the extended section is provided with bolt holes, so that the bolts can be screwed in.

[0041] In this embodiment, the fixed support 3 reduces the influence of the decrease in the shear stiffness of the structure caused by the excessive number of bolts through the extended section.

[0042] like Figure 2 and Fig.10 As shown, the plane side of the limit device 5 is wrapped with a rubber pad 6, and the rubber pad 6 is in direct contact with the replaceable shear-resistant connecting steel beam 2. The rubber pad 6 can increase the friction surface of the replaceable shear-resistant connecting steel beam 2 and improve the lateral stability of the replaceable shear-resistant connecting steel beam 2; that is, the constraint limit is reduced in the longitudinal direction of the pipe gallery 8, and the influence on the deformation joint of the pipe gallery 8 is reduced. The other side of the limit device 5 is arranged with two bolts to connect the first steel frame cross beam 1-2 and the second steel frame cross beam 1-3, combined with Figure 1 As shown, bolt holes are arranged on the first steel frame cross beam 1-2, the second steel frame cross beam 1-3 and the positioning support 4, and the bolt holes are aligned and screwed into the bolt holes to connect and fix the steel frame 1 and the limiting device 5. The position of the limiting device 5 can be flexibly arranged in the placement groove 1-4 according to the internal arrangement of the pipe gallery 8.

[0043] In this embodiment, the limiting device 5 adopts a concave steel plate structure, which includes a first side plate, a second side plate and a third side plate that are connected. The three preferably adopt an integrally formed structure. The first side plate and the second side plate are horizontally symmetrically arranged up and down, and are respectively connected to the first steel frame crossbeam 1-2 and the second steel frame crossbeam 1-3. The third side plate is vertically arranged, and a rubber pad 6 is installed and fixed on the end face. Through the cooperation of the steel frame vertical column 1-1, the steel beam body 2-1 is clamped and fixed.

[0044] like Figure 3 and Fig.11As shown, the positioning support 4 includes two parts, an extended section and an overlap section. Specifically, the overlap section of the positioning support 4 overlaps with the inner end of the first steel frame cross beam 1-2, and the bolt holes thereon overlap, and the steel beam body 2-1 is connected to the first steel frame cross beam 1-2 of the fixed steel frame 1 by bolts. Among them, the extended section of the positioning support 4 is connected to the fixed steel frame 1 by bolts, and the extended section is arranged with bolt holes, so that the bolts can be screwed in. Dividing it into two parts, the extended section and the overlap section, can effectively expand the fixing area and reduce the influence of the dense bolt holes on the structural rigidity of the structure.

[0045] It can be seen that the present embodiment provides an anti-liquefaction device for an integrated pipe gallery joint, which is arranged at the pipe gallery joint. When the pipe gallery is in a liquefied stratum, especially when the joint is close to the boundary between the liquefied stratum and the non-liquefied stratum, the anti-liquefaction ability of the structure can be improved by improving the integrity of the pipe gallery; the replaceable shear-resistant connecting steel beam arranged in the present device can form a function that enables the joint to dissipate seismic energy, and can improve the shear strength at the joint of the pipe gallery structure to a certain extent, so that the seismic effect is better; the replaceable shear-resistant connecting steel beam is easy to disassemble and can be reused, reducing the economic cost of the device; and the replaceable shear-resistant connecting steel beam is fixed by a rubber pad, which can greatly increase the toughness of the structure; the limiting device can change the position of the replaceable shear-resistant connecting steel beam to reduce the impact on the erection of pipelines inside the pipe gallery.

[0046] This embodiment provides a construction method for an anti-liquefaction device for an integrated pipe gallery joint, based on the above-mentioned anti-liquefaction device for an integrated pipe gallery joint, comprising the following steps: Splice and install two sets of steel frame vertical columns 1-1 and the first steel frame crossbeam 1-2 to form two frame bodies; After one of the frame bodies is connected to the inner wall of the pipe gallery 8, the second steel frame cross beam 1-3 is installed on the other frame body, so that the first steel frame cross beam 1-2 and the second steel frame cross beam 1-3 form a placement groove 1-4; A limiting device 5 is installed in the placement groove 1-4, and the two ends of the replaceable shear-resistant connecting steel beam 2 are fixed by the limiting device 5 and the positioning support 4 to realize the connection of the two frame bodies; Adjacent pipe galleries 8 are connected using the fixed supports 3 at the bottom and the fixed supports 3 at the top of the first steel frame cross beam 1 - 2 .

[0047] The more specific steps are as follows: First, lay the fixed steel frame 1, determine the position of the steel frame columns 1-1 on both sides by determining the position of the pipe gallery 8 and mark them, install the first steel frame crossbeam 1-2, use bolts to fix the first steel frame crossbeam 1-2 to the pipe gallery 8, connect the first steel frame crossbeam 1-2 to the steel frame column 1-1 through the steel frame welding point, and connect the second steel frame crossbeam 1-3 to the installed fixed steel frame 1 through the connecting plate 7.

[0048] The steel beam body 2-1 of the replaceable shear-resistant connecting steel beam 2 is installed in the placement groove 1-4 reserved in the pipe gallery 8 through the limiting device 5, and the level 2-2 is installed in the middle position of the steel beam body 2-1. At this time, the limiting device 5 is fixed to the fixed support 3 with bolts, and the upper fixed steel frame 1 and the limiting device 5 are connected to the pipe gallery 8 with bolts.

[0049] In summary, the present invention provides an anti-liquefaction device and method for an integrated pipe gallery joint, which has the following advantages over the existing integrated pipe gallery joint structure: The anti-liquefaction device for the joint of the integrated pipe gallery realizes a stable connection between two adjacent pipe galleries by fixing the steel frame structure, and supplements the structural rigidity; the fixed steel frame is composed of two frame bodies with the same structure, and the frame bodies are connected by replaceable shear-resistant connecting steel beams, which not only improves the stability and strength of the connection, and thus improves the shear resistance, but also facilitates subsequent maintenance and replacement; at the same time, the placement groove formed between the second steel frame cross beam set on the second frame body and the first steel frame cross beam provides a reliable fixed position for one end of the replaceable shear-resistant connecting steel beam, and clamps through the cooperation of the limit device and the steel frame vertical column, further enhancing the firmness of the connection. In addition, the design of the replaceable shear-resistant connecting steel beam enables the device to effectively resist shear deformation and protect the safety of the pipe gallery joint when subjected to external forces such as liquefaction. The steel beam body adopts an I-beam structure, which improves the bearing capacity and stability of the steel beam. At the same time, the level meter set in the middle of the steel beam body can monitor the settlement and deformation of the pipe gallery in real time, providing important data support for the safe operation of the pipe gallery. In terms of the limiting device, a concave steel plate is used as the limiting device, and a rubber pad is used to tightly fit one end of the replaceable shear-resistant connecting steel beam, thereby increasing the friction area and enhancing the shear resistance. The design of the fixed support and the positioning support also fully considers the stability and reliability of the connection, so that the device can be firmly connected to adjacent pipe corridors, and is easy to install and disassemble by bolt connection. Finally, the second steel frame crossbeam is connected to the steel frame vertical column by an L-shaped connecting plate, which not only improves the overall stability and bearing capacity of the frame body, but also simplifies the installation process and improves construction efficiency. In summary, the anti-liquefaction device for the integrated pipe corridor joint provided by the present invention has the advantages of stable connection, high strength, convenient maintenance, and real-time monitoring of settlement deformation. It can effectively improve the anti-liquefaction ability of the pipe corridor joint and ensure the safe operation of the pipe corridor.
