Socket-spigot deformation joint structure for underground utility tunnel, and construction method thereof

Abstract

The invention provides a socket-spigot deformation joint structure for an underground utility tunnel, and a construction method thereof. The structure comprises a tunnel spigot and a tunnel socket, wherein the outer side of the tunnel spigot is wrapped with the tunnel socket and a deformation joint is formed, an upstream slope surface is formed at the outer side of the tunnel socket, a waterproof protection layer is laid on the upstream slope surface, the end part of the tunnel socket is exposed to the outer side of the tunnel spigot and a polystyrene board protection layer is arranged on the end part and / or fine aggregate concrete is filled in the end part, and the polystyrene board protection layer and / or the fine aggregate concrete is integrally connected with the waterproof protection layer; a joint filling material, a joint caulking material and a rubber waterstop are arranged in the deformation joint; and water receiving boxes for sealing the deformation joint are arranged at the inner sides of the tunnel spigot and the tunnel socket along the deformation joint. According to the structure and the construction method thereof, the problem that an adverse effect is generated on a concrete structure because settlement easily occurs in a longitudinal overlong tunnel is solved, and settlement among segments and differential settlement are controlled, so that the structural reliability is enhanced, the stable and safe running of the wire cable of each installation pipeline in the tunnel is guaranteed, and a higher maintenance cost in the later period is avoided.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a socket deformation joint structure of an underground comprehensive pipe gallery and a construction method thereof. Background technique [0002] Urban underground comprehensive pipeline corridor refers to the structures and auxiliary facilities built underground to accommodate two or more types of urban engineering pipelines. By integrating the city's original above-ground and underground power, communication, gas, heating, water supply and drainage and other engineering pipelines into one corridor, it can solve the city's "spider webs in the sky", reduce road excavation and avoid "road zippers", etc. question. It can be managed intensively, reduce operating costs, ensure the safety of pipelines, and release underground space. It reduces the cost of multiple renovations of the road surface and the maintenance cost of engineering pipelines; maintains the integrity of the r...
