[0036] The present application embodiment discloses an assembled multi-cabin pipe gallery structure. Figure 1 and Figure 2 The assembled multi-cabin pipe gallery structure includes multiple sections of prefabricated pipe gallery bodies that can be spliced ​​together to form the multi-cabin pipe gallery structure. Two adjacent prefabricated pipe gallery bodies located in the same longitudinal direction are connected by a sealing component, and two adjacent prefabricated pipe gallery bodies located in the same transverse direction are connected by a locking component.

[0037] The modular prefabricated tunnel body can reduce on-site operation time, and the standardized production process can be used to manufacture high-quality prefabricated tunnel bodies. Under the connection of sealing components and locking components, precise docking between adjacent prefabricated tunnel bodies can be achieved, shortening the installation period and significantly accelerating the progress of the project. At the same time, factory manufacturing can ensure the quality and consistency of the prefabricated tunnel body, avoid secondary masonry filling walls and plastering on site, significantly shorten the construction period and reduce construction costs.

[0038] Reference Figure 2 and Figure 3 The inner wall of the prefabricated pipe gallery body and the four corners of the prefabricated pipe gallery body are integrally formed with reinforcement parts 3. The existence of the reinforcement parts 3 improves the overall strength of the prefabricated pipe gallery body; the end face of the prefabricated pipe gallery body is provided with a first sealing groove 31 and a second sealing groove 32; the first sealing groove 31 is located on the outside of the second sealing groove 32 at intervals.

[0039] The sealing assembly includes a first sealing ring 33 and a second sealing ring 34. The contour of the first sealing ring 33 is consistent with the contour of the first sealing groove 31. The first sealing ring 33 is clamped with the first sealing groove 31 and extends outside the first sealing groove 31. When two adjacent prefabricated pipe gallery bodies located in the same longitudinal direction are spliced, the first sealing ring 33 is clamped between the two first sealing grooves 31. The contour of the second sealing ring 34 is consistent with the contour of the second sealing groove 32. The second sealing ring 34 is clamped with the second sealing groove 32 and extends outside the second sealing groove 32. When two adjacent prefabricated pipe gallery bodies located in the same longitudinal direction are spliced, the second sealing ring 34 is clamped between the two second sealing grooves 32.

[0040] Reference Figure 4 and Figure 5 The prefabricated pipe gallery body located in the middle in the same transverse direction is the middle pipe gallery body 1, and the two prefabricated pipe gallery bodies located on both sides of the middle pipe gallery body 1 in the same transverse direction are both side pipe gallery bodies 2; the side pipe gallery body 2 is connected to the middle pipe gallery body 1 through a locking assembly, and two groups of locking assemblies are arranged on the same side pipe gallery body 2, and the two groups of locking assemblies are arranged at intervals along the longitudinal direction of the side pipe gallery body 2, so that the side pipe gallery body 2 can be more firmly locked on the side of the middle pipe gallery body 1.

[0041] Reference Figure 4 and Figure 6 A mounting groove 11 is provided at the top of one side of the middle pipe gallery body 1 close to the side pipe gallery body 2, and the locking assembly includes a first clamping block 4 which vertically slides on the side pipe gallery body 2 close to the middle pipe gallery body 1, a second clamping block 5 which is arranged in the mounting groove 11, and a locking component which is arranged on the first clamping block 4 and the second clamping block 5 and is used to lock the first clamping block 4 on the second clamping block 5; a driving member for driving the first clamping block 4 to slide vertically is provided on the side pipe gallery body 2.

[0042] The cross-sections of the first clamping block 4 and the second clamping block 5 are both L-shaped, the second clamping block 5 is fixedly connected to the inner side wall of the mounting groove 11, and the second clamping block 5 is located below the first clamping block 4, and the bending portion of the second clamping block 5 is flush with the notch of the mounting groove 11. The bending portion of the first clamping block 4 is clamped with the bending portion of the second clamping block 5, and after the bending portion of the first clamping block 4 is clamped with the bending portion of the second clamping block 5, the locking component locks the first clamping block 4 on the second clamping block 5, so that the first clamping block 4 cannot move upward.

[0043] Therefore, when it is necessary to clamp the side pipe gallery body 2 on the side of the middle pipe gallery body 1, the side pipe gallery body 2 is moved toward the side close to the middle pipe gallery body 1 so that the bent portion of the first clamping block 4 extends into the mounting groove 11, and the first clamping block 4 is driven by the driving member to move downward until the bent portion of the first clamping block 4 is clamped with the bent portion of the second clamping block 5, and under the locking action of the locking member, the first clamping block 4 is locked on the second clamping block 5; thereby completing the connection between the side pipe gallery body 2 and the middle pipe gallery body 1.

[0044] A receiving groove 21 corresponding to the position of the first clamping block 4 is provided on one side of the side pipe gallery body 2 close to the middle pipe gallery body 1, and the driving member is a screw rod 22 vertically penetrated in the receiving groove 21 and rotatably connected to the bottom of the inner wall of the receiving groove 21, and a turntable 221 fixedly connected to the top of the screw rod 22; a moving block 41 is fixedly connected to the side of the first clamping block 4 away from the second clamping block 5, and the moving block 41 vertically slides in the receiving groove 21, and the screw rod 22 vertically penetrates the moving block 41 and is threadedly connected to the moving block 41; thereby, the screw rod 22 is rotated by rotating the turntable 221, and since the screw rod 22 is threadedly connected to the moving block 41, the screw rod 22 drives the first clamping block 4 to rise and fall through the moving block 41.

[0045] A groove 23 matching the turntable 221 is provided on the top surface of the side duct gallery body 2. The turntable 221 is rotatably connected in the groove 23, and the top surface of the turntable 221 is flush with the top surface of the side duct gallery body 2. A hexagonal groove 222 is provided on the top surface of the turntable 221 to facilitate the rotation of the turntable 221 by a corresponding tool.

[0046] Reference Figure 6 and Figure 7 The locking component includes a sleeve 6 fixedly connected to the bottom end of the first clamping block 4, a locking piece radially sliding on the inner side wall of the sleeve 6, a fixed rod 61 arranged on the second clamping block 5 and corresponding to the position of the sleeve 6, a fixed shaft 62 fixedly connected to the top end of the fixed rod 61, a fixed head 63 fixedly connected to the top end of the fixed shaft 62, and an unlocking sleeve 64 sleeved on the circumferential side of the fixed shaft 62 and slidably connected to the fixed shaft 62; a sliding groove 51 corresponding to the position of the fixed rod 61 is opened on the second clamping block 5, the bottom end of the fixed rod 61 is fixedly connected to the bottom of the inner wall of the sliding groove 51, and the sleeve 6 is slidably connected to the sliding groove 51; the locking piece limits the fixed head 63, and the unlocking sleeve 64 unlocks the locking piece from limiting the fixed head 63.

[0047] Reference Figure 7 and Figure 8There are multiple locking members, which are evenly spaced along the inner side wall of the sleeve 6. The inner side wall of the sleeve 6 is provided with placement grooves 65. The number of placement grooves 65 is consistent with the number of locking members and corresponds one to one. The locking member includes a locking block 7 slidably connected in the placement groove 65 and a spring 71 fixedly connected between the placement groove 65 and the locking block 7; a sliding block 72 is fixedly connected to the top and bottom surfaces of the locking block 7. A sliding groove 651 corresponding to the position of the sliding block 72 is provided in the placement groove 65. The sliding block 72 is slidably connected to the sliding groove 651 corresponding to the position, so that the locking block 7 can slide back and forth in the placement groove 65 along the expansion and contraction direction of the spring 71.

[0048] One end of the locking block 7 away from the spring 71 extends into the hollow part of the sleeve 6, and the bottom of the end of the locking block 7 away from the spring 71 is provided with a first chamfer 73, and one end of the fixing head 63 away from the fixing shaft 62 is provided with a first rounded corner 631. When the fixing head 63 extends into the hollow part of the sleeve 6, the first rounded corner 631 of the fixing head 63 abuts against the first chamfer 73 to push the locking block 7 to move in the direction of the compression spring 71 until the fixing head 63 passes over the placement groove 65. Under the resetting action of the spring 71, the locking block 7 is reset to the hollow part of the sleeve 6, so that the locking block 7 is engaged with the fixing head 63, so that the fixing head 63 cannot be separated from the sleeve 6. At this time, there is a gap between the first clamping block 4 and the second clamping block 5, so that the first clamping block 4 can continue to move downward until the fixing head 63 is unlocked from the sleeve 6 by the unlocking sleeve 64.

[0049] A second rounded corner 641 is provided on the circumferential side of the unlocking sleeve 64 and at one end of the unlocking sleeve 64 close to the fixed head 63, and a clearance groove 632 matching the second rounded corner 641 is provided at one end of the fixed head 63 close to the fixed shaft 62 (see FIG. Figure 6), one end of the fixed shaft 62 away from the fixed rod 61 extends into the make way groove 632 and is fixedly connected to the make way groove 632; the second fillet 641 can slide into the make way groove 632; and when the first chamfer 73 of the locking block 7 abuts against the second fillet 641, the second fillet 641 pushes the locking block 7 to move in the direction of the compression spring 71; a third fillet 642 is provided on the circumferential side of the unlocking sleeve 64 and at the end of the unlocking sleeve 64 away from the fixed head 63, and a second chamfer 74 is provided on the top of the end of the locking block 7 away from the spring 71. When the second chamfer 74 of the locking block 7 slides to a position abutting against the third rounded corner 642, the locking block 7 pushes the unlocking sleeve 64 to move in the direction close to the fixed head 63 until the second rounded corner 641 slides into the giving way groove 632, and the unlocking sleeve 64 is limited by the fixed head 63, and the unlocking sleeve 64 cannot continue to move in the direction close to the fixed head 63. At this time, the third rounded corner 642 pushes the locking block 7 to move in the direction of the compression spring 71 through the second chamfer 74, so that the locking block 7 can pass through the placement groove 65, thereby achieving the purpose of allowing the fixed head 63 to be detached from the sleeve 6. That is: when it is necessary to disengage the first clamping block 4 from the second clamping block 5, it is necessary to continue to rotate the screw rod 22 in the same direction so that the screw rod 22 drives the first clamping block 4 to continue to move downward until the second chamfer 74 abuts against the third fillet 642, and then rotate the screw rod 22 in the opposite direction to move the first clamping block 4 upward. At this time, the fixing head 63 can be disengaged from the sleeve 6, and the upward-moving first clamping block 4 can be disengaged from the clamping connection with the second clamping block 5, thereby achieving the purpose of unlocking.

[0050] The top surface of the connection between the side pipe gallery body 2 and the middle pipe gallery body 1 is coated with a waterproof coating layer (not shown in the figure). In the present embodiment, the waterproof coating layer is a polyurethane waterproof coating layer. The polyurethane waterproof coating is a non-tar polyurethane waterproof coating. It uses water as a chain extender and forms an elastic and seamless rubber waterproof layer after curing. The polyurethane waterproof coating has excellent weather resistance, oil resistance, seawater resistance, and corrosion resistance, and can be constructed in a wet state (without visible water) and has strong adhesion.

[0051] The implementation principle of an assembled multi-cabin corridor structure in an embodiment of the present application is as follows: a driving member enables the first clamping block 4 to easily slide vertically, so that the first clamping block 4 can be clamped with the second clamping block 5, thereby ensuring the precise docking between the side corridor body 2 and the middle corridor body 1, thereby enhancing the stability of the entire structure; the provision of the locking component further ensures the reliable locking between the first clamping block 4 and the second clamping block 5, thereby improving the safety performance of the overall structure.

The steel skeleton should avoid the location of the receiving slot and the installation slot. Then the inner mold is installed on the inner side of the steel skeleton, and the outer mold is installed on the outer side of the steel skeleton. Before pouring concrete on the steel skeleton between the inner mold and the outer mold, the first sealing groove, the second sealing groove, the installation slot, the receiving slot and the hoisting hole need to be reserved, and the number and position must be complete. A hoisting ring (not shown in the figure) is embedded in the hoisting hole to facilitate the hoisting of the prefabricated pipe gallery body later.

[0053] After the concrete is poured, it is cured with water, and then the inner and outer molds are removed to form the prefabricated pipe gallery body. When the prefabricated pipe gallery body is hoisted and transported to the construction site after curing, it is necessary to focus on protecting the edges and corners of the prefabricated pipe gallery body and the contact between the chain lock and the lifting ring.

[0055] S3: Slope spraying, foundation pit cushion and cushion waterproofing construction; S4: The prefabricated pipe gallery body is hoisted into the foundation pit using heavy crawler equipment and is sequentially assembled into a multi-cabin pipe gallery structure; The prefabricated pipe gallery bodies are hoisted into the foundation pit according to the predetermined layout, wherein two adjacent prefabricated pipe gallery bodies located in the same longitudinal direction are connected by a sealing component, and two adjacent prefabricated pipe gallery bodies located in the same transverse direction are connected by a locking component; When splicing two prefabricated pipe gallery bodies located in the same longitudinal direction, align the end faces of the prefabricated pipe gallery bodies with the first sealing groove 31 and the second sealing groove 32, and make the first sealing ring 33 snap into the first sealing groove 31, and the second sealing ring 34 snap into the second sealing groove 32; When the side pipe gallery body 2 needs to be clamped on the side of the middle pipe gallery body 1, the side pipe gallery body 2 is moved toward the side close to the middle pipe gallery body 1 so that the bent portion of the first clamping block 4 extends into the mounting groove 11, and the first clamping block 4 is driven by the driving member to move downward until the bent portion of the first clamping block 4 is clamped with the bent portion of the second clamping block 5, and under the locking action of the locking member, the first clamping block 4 is locked on the second clamping block 5.

[0056] S5: Waterproof construction of the top and sides of the prefabricated pipe gallery; S6: According to the design drawings and specification requirements, the backfill is divided into layers and compacted layer by layer. Only after passing the inspection can the next layer of earth backfill construction be carried out.
