Description

Technical Field

[0001] The invention belongs to the technical field of pipe gallery, in particular to a prefabricated assembly device and an assembly method for an underground comprehensive pipe gallery. Background Art

[0002] A comprehensive pipeline corridor is an underground tunnel space that accommodates various municipal, power, communication, gas and other pipelines and is equipped with special inspection ports and monitoring systems; the assembled comprehensive pipeline corridor is an intensive and sustainable way of laying underground pipelines. On the one hand, it facilitates the maintenance and updating of pipelines, avoids the repeated excavation of urban roads and the various problems caused by it, and on the other hand, it also improves the service life of pipelines.

[0003] The construction technology of the integrated pipeline corridor can be mainly divided into cast-in-place method and prefabricated assembly method. The cast-in-place method is the on-site concrete pouring, and the prefabricated assembly method requires the pouring of prefabricated pipeline corridor segments, which are then transported to the site for assembly. Compared with the cast-in-place integrated pipeline corridor, the prefabricated assembly pipeline corridor has the advantages of good construction quality, short construction period and less environmental pollution.

[0004] However, at present, when assembling prefabricated pipe corridors, cranes are often used to assemble the prefabricated pipe corridors due to their large size and weight. However, the cranes have problems such as unstable foundations and deformation and vibration of the booms. It takes a long time to connect each pipe corridor segment, and it is difficult to ensure the connection quality.

[0005] To this end, the present invention provides a prefabricated assembly device and an assembly method for an underground comprehensive pipe gallery. Summary of the invention

The underground comprehensive pipe gallery prefabrication and assembly equipment according to claim 5 is characterized by: A suction plate (11) is fixedly mounted on one side of each support column (6) close to the inner wall of the pipe gallery; the surface of the suction plate (11) is concave and made of rubber; and a plurality of rubber balls (12) are mounted on the inner wall of the suction plate (11).

7. The underground comprehensive pipe gallery prefabrication and assembly equipment according to claim 5 is characterized by: A guide frame (13) is fixedly mounted on the outer surface of the traction rod (202); a plurality of guide frames (13) are provided and are arranged in a circular array on the surface of the traction rod (202); a guide rod (14) is fixedly mounted on the surface of each guide frame (13); the outer surface of the circular seat (201) is provided with guide grooves (15) arranged in a circular array; the guide grooves (15) and the guide rods (14) are arranged in a one-to-one correspondence.

8. The underground comprehensive pipe gallery prefabrication and assembly equipment according to claim 7 is characterized by: A concave groove (16) is provided in the middle of the surface of the circular seat (201); the shape of the concave groove (16) is matched with the shape of the traction rod (202).

9. The underground comprehensive pipe gallery prefabrication and assembly equipment according to claim 7 is characterized by: The lower surface of the traction rod (202) is slidably connected to a supporting plate (17); the supporting plate (17) is in the shape of an arc.

10. A method for prefabrication and assembly of an underground utility corridor, the method using an underground utility corridor prefabrication and assembly device as claimed in any one of claims 1 to 9; characterized in that: The following steps are involved: S1. When assembling a pair of pipe gallery bodies (1), firstly place two guide rails (7) on one side of the pipe gallery body, and place two assembly seats (2) on the inner walls of the two pipe gallery bodies respectively, and then drive the rotating rod (3) to rotate through the output end of the driving motor, and the rotating rod (3) drives the arc plate (4) and the arc pressure column (5) to rotate; S2, when the arc-shaped pressure column (5) rotates, it will contact and press against one end of the support column (6), so that the support column (6) moves toward the inner wall of the pipe gallery, and then the support columns (6) at different positions will contact the inner wall of the pipe gallery, so that the support columns (6) are pressed against the inner walls of the two pipe gallery bodies, and then the push rod at one end of the tractor is pressed against one end of the traction rod (202), so that the tractor pushes the traction rod (202) to move toward the upper side of the guide track (7); S3, the traction rod (202) drives the circular seat (201) and the support column (6) to move. Since the support column (6) is fixed on the inner wall of the pipe gallery body, the traction rod (202) will drive one of the pipe gallery bodies to move on the surface of the guide track (7). Then, the two pipe gallery bodies approach each other, and the annular plate of one pipe gallery body will be embedded in the annular groove on the surface of the other pipe gallery body. At this time, the prefabrication and assembly of the two pipe gallery bodies can be completed. Then, the rotating rod (3) is rotated in the opposite direction to separate the arc-shaped pressure column (5) from the support column (6), and the assembly seat (2) can be taken out, so as to facilitate the use of the assembled pipe gallery body.
