Abstract

The invention discloses a method for constructing an urban utility tunnel. The method comprises the steps that firstly, a base plate of the utility tunnel and a 50+ / -10cm side wall are poured; secondly, after concrete pouring for the first time is completed, and the strength of concrete reaches 80+ / -5% of the design strength, a movable formwork rail of the utility tunnel is laid on the base plate of the utility tunnel; then, a utility tunnel body is erected on the movable formwork rail of the utility tunnel; the residual part of the side wall and a top plate of the utility tunnel are poured with concrete on the utility tunnel body, after the strength of the concrete reaches 80+ / -5% of the design strength, a jackscrew is adjusted to be lower, and a split bolt is disassembled; when a side template of an inner mold is naturally drooping under the gravity, a movable formwork structure of the utility tunnel is driven to move to a next station so as to realized synchronous forward movement; finally, an outer template is suspended by adopting a crane, the crane moves along a lower sliding rail to the next station; and the above steps is repeated to complete the construction of the whole urban utility tunnel. The invention provides the method for the utility tunnel of a formwork framework capable of being repeatedly used and automatically walking. The method has the advantage that repeated construction of frame bodies and templates can be reduced.

Description

technical field [0001] The invention relates to the technical field of municipal public facilities, in particular to a method for constructing an urban pipe corridor. Background technique [0002] The urban comprehensive pipeline corridor is built underground in the city to accommodate structures and auxiliary facilities of two or more types of urban engineering pipelines. The comprehensive pipeline corridor is the comprehensive corridor of underground urban pipelines. Build a tunnel space underground in the city, integrate various engineering pipelines such as power, communication, gas, heating, water supply and drainage, etc., and set up special inspection ports, hoisting ports and monitoring systems, and implement unified planning, unified design, and unified Construction and management are the important infrastructure and "lifeline" to ensure the operation of the city. It is a municipal public facility that implements unified planning, design, construction and maintena...
