Description
Technical Field
[0001] The utility model relates to the technical field of highway engineering construction, and specifically relates to a relay structure for jacking of extra-large cross-section box culverts. Background Technique
[0002] With the rapid advancement of the urbanization process, the rational development and utilization of underground space has become a key approach to solving urban traffic congestion and optimizing the urban spatial layout. In particular, the construction of extra-large cross-section underground channels, as an important part of urban traffic infrastructure, has become increasingly prominent. However, in the construction practice of such underground channels, the challenges and limitations faced by traditional box culvert jacking technology have gradually emerged.
[0003] First of all, during the jacking process of traditional extra-large cross-section box culverts, due to the lack of an effective guiding mechanism, it is difficult to ensure the splicing accuracy between box culvert segments. This not only increases the workload of subsequent adjustments but also may affect the structural stability and use safety of the entire underground channel. Secondly, since the box culvert slides directly on the ground for jacking, this direct-contact sliding brings a large frictional force, thus increasing the resistance during the jacking process. This not only places higher requirements on the jacking equipment but also may lead to a reduction in construction efficiency and an increase in costs. In addition, after the box culvert is spliced, due to insufficient sealing at the contact position, water seepage is likely to occur at the joints. This not only affects the construction quality and overall stability of the underground channel but also may pose potential safety hazards to subsequent use and maintenance, increasing the maintenance cost. Summary of the Invention
[0004] The technical problem to be solved by the utility model is to provide a relay structure for jacking of extra-large cross-section box culverts to solve the technical problems proposed in the background technique.
[0005] To solve the above technical problems, the technical solution adopted by the utility model is: a relay structure for jacking of extra-large cross-section box culverts, including a front section frame, a pin slot, a first lap plate, a second lap plate, a pin, a rear section frame, a first jack socket, a second jack socket, a first card slot, and a second card slot;
[0006] One end of the front section frame is fixed with a concrete cutting edge, and several pin slots are fixed inside the other end of the front section frame. A first card slot is opened on the outer side surface of the front section frame near the pin slot, and a first lap plate is arranged inside the first card slot. The first lap plate is fixed to the front section frame through anchor bars;
[0007] The second lap plate is slidably installed on the inner lower side surface of the first lap plate. The second lap plate is arranged inside the second card slot and is fixed to the rear section frame through anchor bars;
[0008] The second card slot is opened on the outer side of one end of the rear section frame close to the front section frame. A plurality of pins are fixed at one end of the rear section frame close to the second connecting plate. The pins are arranged corresponding to the pin slots, and the diameter of the pins is smaller than that of the pin slots.
[0009] A plurality of first jack sockets are opened at one end of the front section frame close to the rear section frame. A second jack socket is opened at one end of the rear section frame far from the front section frame. Jacks are arranged inside both the first jack socket and the second jack socket. First protective plates are fixed at both ends of each jack.
[0010] The first protective plates at both ends of the jack inside the first jack socket are respectively fixed to the front section frame and the rear section frame. The first protective plates at both ends of the jack inside the second jack socket are respectively fixed to the rear section frame and the back wall. The back wall is arranged on one side of the rear section frame and is fixed to the ground.
[0011] In a preferred solution, the first connecting plate includes a plate body and an arc-shaped plate. The plate body is arranged on the outer side of the first card slot, and the inner wall of the plate body is fixed to the front section frame through anchor bars.
[0012] The lower side inside the plate body is slidably connected to the second connecting plate, and an arc-shaped plate is fixed by welding at one end of the plate body far from the front section frame.
[0013] In a preferred solution, the pin is a columnar structure formed by welding four steel plates. A support frame is fixed inside the columnar structure by welding.
[0014] The side length of one end of the pin close to the front section frame is smaller than that of the end far from the front section frame.
[0015] In a preferred solution, a second protective plate is fixed to one end of the rear section frame close to the front section frame through anchor bars.
[0016] A relay jack structure for jacking of an extra-large cross-section culvert box provided by the present utility model has the following beneficial effects by adopting the above structure:
[0017] (1) Through the cooperative design of the first connecting plate and the second connecting plate, not only can the second connecting plate smoothly enter the inside of the first connecting plate, but also the splicing of the rear section frame and the front section frame can be guided. In addition, the sealing degree between the rear section frame and the front section frame can be improved, avoiding water seepage and other situations between the rear section frame and the front section frame. At the same time, when the rear section frame gradually approaches the front section frame, the second connecting plate will slide inside the first connecting plate, and the resistance during this sliding is smaller than the resistance when the rear section frame directly slides on the ground.
[0018] (2) Through the cooperative design of the pin and the pin slot, when the rear section frame gradually approaches the front section frame, the pin will slide and insert into the corresponding pin slot, so as to guide the movement of the rear section frame through the cooperation of the pin and the pin slot, and avoid the dislocation between the rear section frame and the front section frame when they are attached to each other.

[0028] As Figure 1-7 shown in, a relay structure for the jacking of a super-large cross-section culvert box includes a front section frame 1, a pin slot 2, a first latching plate 3, a second latching plate 4, a pin 5, a rear section frame 6, a first jack socket 7, a second jack socket 8, a first card slot 9, and a second card slot 10;
[0029] One end of the front section frame 1 is fixed with a concrete blade, several pin slots 2 are fixed inside the other end of the front section frame 1, a first card slot 9 is opened on the outer side of the front section frame 1 near the pin slot 2, a first latching plate 3 is arranged inside the first card slot 9, and the first latching plate 3 is fixed to the front section frame 1 through anchor bars;
[0030] The inner lower side of the first bridging slab 3 is slidably installed with a second bridging slab 4. The second bridging slab 4 is arranged inside the second card slot 10, and the second bridging slab 4 is fixed to the rear-section frame 6 through anchor bars;
[0031] The second card slot 10 is opened on the outer side of one end of the rear-section frame 6 close to the front-section frame 1. A plurality of pins 5 are fixed to one end of the rear-section frame 6 close to the second bridging slab 4. The pins 5 are correspondingly arranged with the pin slots 2, and the diameter of the pins 5 is smaller than the diameter of the pin slots 2;
[0032] A plurality of first jack pits 7 are opened at one end of the front-section frame 1 close to the rear-section frame 6. A plurality of second jack pits 8 are opened at one end of the rear-section frame 6 far from the front-section frame 1. Jacks are arranged inside both the first jack pits 7 and the second jack pits 8, and first protective plates are fixed to both ends of the jacks;
[0033] The first protective plates at both ends of the jack inside the first jack pit 7 are respectively fixed to the front-section frame 1 and the rear-section frame 6. The first protective plates at both ends of the jack inside the second jack pit 8 are respectively fixed to the rear-section frame 6 and the back wall. The back wall is arranged on one side of the rear-section frame 6 and is fixed to the ground.
[0034] In a preferred solution, the first bridging slab 3 includes a plate body 31 and an arc-shaped plate 32. The plate body 31 is arranged on the outer side of the first card slot 9, and the inner wall of the plate body 31 is fixed to the front-section frame 1 through anchor bars;
[0035] The inner lower side of the plate body 31 is slidably connected to the second bridging slab 4, and an arc-shaped plate 32 is fixed to one end of the plate body 31 far from the front-section frame 1 by welding.
[0036] One end of the arc-shaped plate 32 is arranged between the plate body 31 and the second bridging slab 4. When the second bridging slab 4 is slidably installed into the first bridging slab 3 through the jack inside the second jack pit 8, the arc-shaped plate 32 can enable the second bridging slab 4 to smoothly enter the first bridging slab 3. As the second bridging slab 4 gradually moves, the arc-shaped plate 32 will gradually enter between the plate body 31 and the second bridging slab 4 under the extrusion of the plate body 31 and the rear-section frame 6, filling the gap between the plate body 31 and the second bridging slab 4, thereby sealing between the front-section frame 1 and the rear-section frame 6. At the same time, during the process of the rear-section frame 6 gradually approaching the front-section frame 1, the second bridging slab 4 will slide inside the first bridging slab 3, and the resistance during this sliding will be smaller than the resistance when the rear-section frame 6 directly slides on the ground.
[0037] In a preferred solution, the pin 5 is a columnar structure formed by welding four steel plates, and a support frame is fixed inside the columnar structure by welding;
[0038] The side length of one end of the pin 5 close to the front-section frame 1 is smaller than the side length of the end far from the front-section frame 1.
[0039] When the rear frame 6 gradually approaches the front frame 1, the pin 5 will slide and insert into the corresponding pin slot 2. Thus, through the cooperation of the pin 5 and the pin slot 2, the movement of the rear frame 6 is guided to avoid misalignment between the rear frame 6 and the front frame 1 when the rear frame 6 is arranged in contact with the front frame 1.
[0040] In a preferred solution, a second protective plate is fixed by anchor bars at one end of the rear frame 6 close to the front frame 1.
[0041] This second protective plate can prevent the rear frame 6 and the front frame 1 from colliding when they are in contact, resulting in fragmentation of the rear frame 6 and the front frame 1.
[0042] The working principle of a relay structure for jacking of a super-large cross-section culvert box disclosed by the present utility model is as follows:
[0043] During use, first, the front frame 1 is inserted into the ground by the jack in the first jack pit 7. Then, the jack in the second jack pit 8 drives the rear frame 6 to gradually approach the front frame 1. At the same time, the jack in the first jack pit 7 contracts correspondingly. Moreover, the second connecting plate 4 gradually enters into the first connecting plate 3, and the pin 5 enters into the corresponding pin slot 2. After the rear frame 6 is in contact with the front frame 1, by repeating the above operations, the front frame 1 and the rear frame 6 are moved to the corresponding positions.
