Up-and-down split type prefabricated pipe gallery and prefabrication method

Abstract

The invention discloses an up-and-down split type prefabricated pipe gallery and a prefabrication method, and relates to the technical field of comprehensive pipe galleries. The up-and-down split type prefabricated pipe gallery comprises an upper pipe gallery body and a lower pipe gallery body. The upper pipe gallery body comprises a top plate and two upper side plates. The lower pipe gallery body comprises a bottom plate and two lower side plates. The two upper side plates are in matched connection with the two lower side plates, and an empty bin is arranged inside. The prefabrication method comprises the steps of pedestal embedding and leveling, modeling, concrete pouring and vibrating, steam constant-temperature maintenance (adopting a shed cover method), demolding and natural maintenance. According to the up-and-down split type prefabricated pipe gallery, an up-and-down split type structure is adopted, split type horizontal pouring is adopted, the one-piece pouring weight can be reduced, transporting and mounting are facilitated, and the pouring quality is good.

Description

technical field [0001] The invention relates to the technical field of a comprehensive pipe gallery for urban underground pipe network systems, in particular to an upper and lower split prefabricated pipe gallery and a prefabrication method. Background technique [0002] The comprehensive pipe corridor refers to the construction of a municipal shared tunnel under the urban road, which integrates various municipal pipelines such as electricity, communication, water supply, and gas, and implements "unified planning, unified construction, and unified management" to achieve the purpose of underground space. Comprehensive utilization and resource sharing. [0003] The construction of traditional comprehensive pipe gallery generally adopts on-site pouring, which requires processing and binding of steel bars, formwork support, concrete pouring, maintenance, formwork removal and other processes on the construction site. This method not only has complicated construction procedures an...

AI Technical Summary

Problems solved by technology

[0007] 1) Due to the high height and heavy weight of the prefabricated pipe gallery, mold expansion often occurs at the lower part of the mold during pouring, resulting in mold damage;

[0008] 2) Since the mold is integral, when concrete is poured into the mold from top to bottom, the air and air bubbles at the bottom of the mold cannot be completely discharged, resulting in honeycomb defects in the bottom plate of the formed pipe gallery, and even partial exposure The rib phenomenon seriously affects the structural strength, service life and sealing performance;

[0009] 3) After pouring, demoulding is difficult, and abrasive tools are easy to wear, reducing the service life of the mold

[0011] 1) The pouring top surface of the mold is the matching surface during the assembly of the pipe gallery. If vertical integral pouring is adopted, the mold cannot guarantee the flatness of the poured surface, which will affect the subsequent assembly and sealing of the pipe gallery
