In the construction of prefabricated pipe corridors, there are certain safety risks in the lifting and assembly operations. Moreover, the lifting method cannot effectively make the prefabricated pipe corridors docked, and adjustments are required, thereby reducing the efficiency of pipe corridor construction.

[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0046] Reference Figures 1-10 A pipe gallery prefabrication and assembly construction process includes the following construction steps:

[0047] S1. According to the project requirements, carry out detailed design of the pipeline corridor and division of prefabricated sections, and carry out foundation pit construction at the construction site.

[0048] S2. Install the supporting steel plate 1 in the foundation pit according to the starting section of the pipe gallery, and use the lifting equipment to lift the prefabricated pipe gallery segments 2 in sequence and transport them to the top of the foundation pit.

[0049] S3. Transport the lifted prefabricated pipe gallery segment 2 to the installation location through the transport mechanism.

[0050] S4. Install the prefabricated pipe gallery segment 2 to the designated position through the positioning and clamping mechanism to ensure accurate docking.

[0051] S5. Connect the prefabricated pipe gallery segments 2 through a connecting mechanism.

[0052] S6. Repeat steps S3 and S4 until the standard corridor stage installation is completed, and connect multiple prefabricated corridor segments 2 under the action of the tensioning equipment to form an overall corridor.

[0053] In order to facilitate the transportation of the prefabricated pipe gallery segment 2 that has been hoisted, the transportation mechanism includes transportation rails 3 that are symmetrically installed on the outer surface of the foundation pit. The surfaces of the moving blocks on the two transportation rails 3 are fixedly installed with installation shells 301, and the inner walls of the two installation shells 301 are symmetrically installed with telescopic cylinders 302. One end of the piston rod of the two telescopic cylinders 302 extends to the outside of the installation shell 301 and is fixedly connected to a clamping frame 303. The installation shell 301 is driven to move by the movement of the moving block on the transportation rail 3, and the clamping frame 303 connected thereto is driven to move by the telescopic movement of the piston rod of the telescopic cylinder 302.

[0054] In order to clamp the prefabricated pipe gallery segment 2 that is hoisted, grooves 304 are opened on the surfaces of the two clamping frames 303 in a left-right symmetrical distribution. The inner wall of the groove 304 is installed with a screw 305 through a bearing. The outer surface of the clamping frame 303 is installed with a drive motor 306 in a left-right symmetrical distribution. One end of the output shaft of the drive motor 306 is fixedly sleeved with one end of the screw 305. The surface of the screw 305 is threadedly sleeved with a thread block 307. The surface of the thread block 307 is slidably engaged with the inner wall of the groove 304. One side of the thread block 307 A mounting block 308 is fixedly connected to the surface, and a vacuum suction cup 309 is embedded on one side surface of the mounting block 308. The rotation of the output shaft of the driving motor 306 drives the screw 305 connected to it to rotate, and the rotation of the screw 305 drives the threaded block 307 connected to it to move along the inner wall of the groove 304. The movement of the threaded block 307 drives the mounting block 308 connected to it to move, and the movement of the mounting block 308 drives the vacuum suction cup 309 to move, thereby facilitating the vacuum suction cup 309 and the mounting block 308 to adsorb and clamp the prefabricated pipe gallery segment 2.

[0055] In order to support the mounting block 308 and facilitate the movement of the mounting block 308, a reinforcement frame 310 is installed on the surface of the clamping frame 303 in a symmetrical distribution in the upper and lower directions. The upper and lower surfaces of the mounting block 308 are provided with a slide groove 311, and one side surface of the reinforcement frame 310 is slidably engaged with the inner wall of the slide groove 311.

[0056] By setting up a transportation mechanism, it is convenient to clamp the hoisted prefabricated pipe gallery segment 2, so as to preliminarily position the prefabricated pipe gallery segment 2. The driving motor 306 drives the installation block 308 to move, so that the installation block 308 clamps the prefabricated pipe gallery segment 2. At the same time, the vacuum suction cup 309 on the installation block 308 adsorbs the prefabricated pipe gallery segment 2 and transports it under the action of the transportation track 3, thereby achieving the positioning and transportation effect.

[0057] In order to facilitate the movement of the positioning and clamping mechanism, the positioning and clamping mechanism includes a bracket 4 arranged outside the transport track 3. Four moving wheels 401 are symmetrically distributed on the bottom of the bracket 4. The bracket 4 is moved by driving the moving wheels 401.

[0058] In order to facilitate the clamping of the prefabricated pipe gallery segment 2 transported by the transportation mechanism, the first self-driving slide rail 402 and the second self-driving slide rail 403 are symmetrically installed on the upper and lower surfaces of the bracket 4, and the slider surface of the first self-driving slide rail 402 is fixedly connected to the connecting frame 404, and the slider surface of the second self-driving slide rail 403 is fixedly connected to the connecting plate 405. The inner surface of the connecting frame 404 is slidably connected to the outer surface of the bracket 4, and the sliders on the first self-driving slide rail 402 and the second self-driving slide rail 403 move synchronously relative to each other, thereby driving the connecting plate 405 and the connecting frame 404 to move relative to each other.

[0059] In order to facilitate the placement of the prefabricated pipe gallery segment 2 on the supporting steel plate 1, multi-stage hydraulic telescopic rods 406 are fixedly installed on the lower surfaces of the connecting plate 405 and the connecting frame 404, and one end of the two multi-stage hydraulic telescopic rods 406 is fixedly connected to a connecting block 407, and a clamping plate 408 is fixedly installed on the opposite side surface of the two connecting blocks 407. The opposite side surfaces of the two clamping plates 408 are provided with L-shaped clamping blocks 409 distributed in a rectangular array. The surface of the L-shaped clamping block 409 contacts the surface of the prefabricated pipe gallery segment 2, and the surface of the L-shaped clamping block 409 contacts the surface of the supporting steel plate 1. The expansion and contraction of the multi-stage hydraulic telescopic rods 406 drives the connecting block 407 connected thereto to move up and down, and the up and down movement of the connecting block 407 drives the clamping plate 408 to move up and down, and the up and down movement of the clamping plate 408 drives the L-shaped clamping block 409 to move up and down, thereby driving the prefabricated pipe gallery segment 2 clamped by the L-shaped clamping block 409 to be placed on the supporting steel plate 1.

[0060] In order to determine the position of the prefabricated pipe gallery segment 2, a laser sensor 410 is installed on the surface of the bracket 4 close to the second self-driving slide rail 403, and the laser sensor 410 uses a laser beam to accurately measure the distance.

[0061] By setting up a positioning and clamping mechanism, it is convenient to clamp the transported prefabricated pipe gallery segment 2. The position of the prefabricated pipe gallery segment 2 is determined by the laser sensor 410. The telescopic movement of the multi-stage hydraulic telescopic rod 406 drives the connecting block 407, the clamping plate 408 and the L-shaped clamping block 409 to pass through the clamping frame 303, and drives the L-shaped clamping block 409 to clamp the prefabricated pipe gallery segment 2 under the relative movement of the sliders on the first self-driving slide rail 402 and the second self-driving slide rail 403. Then, under the action of the multi-stage hydraulic telescopic rod 406, the prefabricated pipe gallery segment 2 is placed on the supporting steel plate 1 in the foundation pit, thereby achieving the positioning effect.

[0062] In order to connect two prefabricated pipe gallery segments 2 together, the connecting mechanism includes connecting components 5 installed in a rectangular array on the upper surface of the prefabricated pipe gallery segment 2. The inner walls of multiple connecting components 5 are threadedly connected with steel bars 51, and a connecting threaded sleeve 52 is threadedly sleeved between two steel bars 51. The position of the prefabricated pipe gallery segment 2 is adjusted by connecting the steel bars 51 with the connecting components 5, and the steel bars 51 on the two prefabricated pipe gallery segments 2 are connected together by the connecting threaded sleeve 52, so that the two prefabricated pipe gallery segments 2 are connected together.

[0063] By setting up a connecting mechanism, it is convenient to connect the two prefabricated pipe gallery segments 2 by threading the steel bars 51 with the connecting components 5 in sequence when the two prefabricated pipe gallery segments 2 are connected, and then the two steel bars 51 are connected together by connecting the threaded sleeves 52, so that the two prefabricated pipe gallery segments 2 can be installed together, thereby improving the docking efficiency of the prefabricated pipe gallery segments 2.

[0064] Working principle: When in use, the prefabricated pipe gallery segment 2 is first transported to the middle of the transport mechanism through the lifting equipment, and then the telescopic cylinder 302 is started. The telescopic piston rod of the telescopic cylinder 302 drives the clamping frame 303 connected thereto to move, so that the mounting blocks 308 on the two clamping frames 303 contact each other, and then the driving motor 306 is started. The rotation of the output shaft of the driving motor 306 drives the screw rod 305 connected thereto to rotate. The rotation of the screw rod 305 drives the threaded block 307 connected thereto to move along the inner wall of the groove 304. The movement of the threaded block 307 drives the mounting block 308 connected thereto to move. The movement of the mounting block 308 causes the reinforcement frame 310 to slide in the slide groove 311. At the same time, the movement of the mounting block 308 drives the vacuum suction cup 309 to move, thereby facilitating the vacuum suction cup 309 and the mounting block 308 to adsorb and clamp the prefabricated pipe gallery segment 2.

[0065] Then, the movement of the moving block on the transport track 3 drives the installation housing 301 to move, thereby driving the clamped prefabricated pipe gallery segment 2 to move;

[0066] When the laser sensor 410 on the bracket 4 detects the position of the prefabricated pipe gallery segment 2, one end of the multi-stage hydraulic telescopic rod 406 extends to drive the connecting block 407, the clamping plate 408 and the L-shaped clamping block 409 to pass through the clamping frame 303 until the four L-shaped clamping blocks 409 are aligned with the four corners of the prefabricated pipe gallery segment 2. Then, the first self-driving slide rail 402 and the second self-driving slide rail 403 are started, so that the sliders on the first self-driving slide rail 402 and the second self-driving slide rail 403 drive the multi-stage hydraulic telescopic rod 406 thereon to move relative to each other, and the L-shaped clamping block 409 is driven by the relative movement of the two multi-stage hydraulic telescopic rods 406 to clamp the prefabricated pipe gallery segment 2;

[0067] Then, the vacuum suction cup 309 is released, causing the output shaft of the drive motor 306 to rotate in the opposite direction and drive the mounting block 308 to reset. Then, the piston rod of the telescopic cylinder 302 contracts and drives the clamping frame 303 to reset. Then, the multi-stage hydraulic telescopic rod 406 continues to extend and drives the prefabricated pipe gallery segment 2 to move downward and contact the supporting steel plate 1.

[0068] Then the sliders on the first self-driving slide rail 402 and the second self-driving slide rail 403 drive the multi-stage hydraulic telescopic rod 406 thereon to move away from each other, and reset the piston rod of the multi-stage hydraulic telescopic rod 406, and then drive the bracket 4 to move to the next installation position through the moving wheel 401;

[0069] Then repeat the above steps to dock the second prefabricated pipe gallery segment 2 with the first prefabricated pipe gallery segment 2, and connect the two prefabricated pipe gallery segments 2 together through the threaded connection of the steel bar 51 and the connecting member 5, and at the same time connect the two steel bars 51 together through the connecting threaded sleeve 52.

[0070] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
