Mortise type prefabricated comprehensive pipe gallery longitudinal connector

Abstract

The invention discloses a mortise type prefabricated comprehensive pipe gallery longitudinal connector. The mortise type prefabricated comprehensive pipe gallery longitudinal connector comprises prefabricated pipe gallery sections (1), longitudinal prestress ribs (2) and waterstop rubber belts (3), wherein each prefabricated pipe gallery section (1) comprises a top plate (4), side plates (5) and a bottom plate (6). Tenon-and-mortise components which are matched with each other are arranged at the two ends of each pipe gallery section. During on-site construction and splicing, every two adjacent pipe gallery sections are matched with each other according to the tenon-and-mortise relationship, the waterstop rubber belts are reasonably arranged on joints, then prestress is applied through the longitudinal prestress ribs for tensioning, and thus an integral structure is formed by a prefabricated pipe gallery. According to the mortise type prefabricated comprehensive pipe gallery longitudinal connector, the good mechanical property and waterproof performance of the mortise type connector are utilized, the prestress ribs are used for tensioning, the waterstop rubber belts are used for preventing water, and thus the structural integrity of the prefabricated pipe gallery is improved. Abundant structural forms of the prefabricated comprehensive pipe gallery longitudinal connector are provided, and convenience is provided for further development of the structure of the prefabricated comprehensive pipe gallery.

Description

technical field [0001] The invention belongs to the field of underground structures and relates to a longitudinal joint of a comprehensive pipe gallery, in particular to a longitudinal joint of a tongue-and-groove type prefabricated comprehensive pipe gallery. Background technique [0002] Urban underground comprehensive pipe gallery, also known as underground common ditch, refers to the centralized setting of two or more urban underground pipelines in the same tunnel space, and setting up special maintenance ports, hoisting ports and monitoring systems to implement unified planning, design and construction. , common maintenance, centralized management, formed a modern, intensive urban infrastructure. The underground comprehensive pipe gallery can effectively utilize the underground space resources, is beneficial to the comprehensive management, monitoring and maintenance of the pipeline, prolong the service life of the pipeline, and avoid the repeated excavation of the road...
