Prefabricated comprehensive pipe gallery for bearing capacity of enclosure structure and its construction method

Abstract

The invention discloses an assembly type utility tunnel for building envelop bearing strength and a construction method thereof. The structure is formed by two parts of a building envelop and a prefabricated utility tunnel by casting in place and connecting, the building envelop comprises a triaxial soil-cement stirring pile and a drill hole cast-in-place pile, the top of the drill hole cast-in-place pile is reserved with longitudinal reinforcements, the inner side, near the bottom of a foundation pit, of the drill hole cast-in-place pile is reserved with pre-embedded reinforcements; the top of the prefabricated utility tunnel is provided with a set of structural beams at intervals, the top of each structural beam is provided with a lap plate, the two ends of each lap plate are reserved with lap plate reserved reinforcements extending outward, the two sides of the bottom of the prefabricated utility tunnel are reserved with bottom plate reserved reinforcements extending outward, pile top reserved reinforcements are connected with the lap plate reserved reinforcements, and the pre-embedded reinforcements are connected with the bottom plate reserved reinforcements. According to the assembly type utility tunnel for building envelop bearing strength and the construction method thereof, nodes of the prefabricated utility tunnel are all in cast-in-place connection with the reinforcements of the drill hole cast-in-place pile, the damage of uneven settlement caused by foundation subsidence is prevented, the construction period is shortened, and the assembly type utility tunnel is economic and environmental.

Description

technical field [0001] The invention belongs to the technical field of underground engineering construction, and in particular relates to a prefabricated comprehensive pipe gallery for load bearing of an enclosure structure and a construction method thereof. Background technique [0002] The underground comprehensive pipe corridor is the "underground urban pipeline comprehensive corridor", that is, the public pipeline tunnel built underground in the city, and more than two kinds of municipal pipelines such as electricity, communication, gas, water supply, heat, and drainage are laid in the tunnel in a concentrated manner, and unified Planning, design, construction and maintenance form a modern, scientific and intensive urban infrastructure. Commonly known as the lifeline project, the underground comprehensive pipe corridor is the key to maintaining the normal operation of modern city functions. Its advantages are: one-time excavation, centralized construction, avoiding repe...

Problems solved by technology

This method takes a long time to construct, consumes a lot of materials, and is costly. Moreover, even if the muddy foundation has been treated with soft foundation, uneven settlement will occur after long-term use, and it will also bring various hidden dangers to the operation of the prefabricated integrated pipe gallery.
