Pouring construction method for tunnel inverted arch and inverted arch filling

Abstract

The invention provides a pouring construction method for a tunnel inverted arch and inverted arch filling. The pouring construction method comprises the steps that two concrete conveying devices are correspondingly moved to the two sides of a tunnel; concrete is injected into one end of the concrete conveying device, and the concrete conveying device conveys the concrete to the other end of the concrete conveying device; the concrete is distributed at the other end of the concrete conveying device, so that the concrete is conveyed to the inverted arch, and the inverted arch is poured; and after inverted arch pouring is completed, the concrete is distributed at the other end of the concrete conveying device again, so that the concrete is conveyed to inverted arch filling and inverted arch filling for pouring till inverted arch filling and pouring are completed. The inverted arch and the inverted arch filling are poured, so that the pouring operation of the inverted arch and the inverted arch filling is simpler and more convenient, the working efficiency is improved, the safety is improved, a vehicle can normally pass through an inverted arch trestle, each working procedure of the tunnel can be continuously constructed without interruption, and the construction speed is ensured.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a tunnel inverted arch and a pouring construction method for filling the inverted arch. Background technique [0002] During tunnel construction, concrete is poured for the inverts and the invert fills. The existing practice is generally to set an inverted arch trestle in the middle of the tunnel, and then directly drive the concrete tank truck loaded with concrete to the inverted arch trestle, and stay on the inverted arch trestle, and then pour the concrete into the inverted arch trestle. Arches and inverted arches are filled with pouring. [0003] During the pouring process, it is necessary to manually stand beside the concrete truck to adjust the blanking position of the concrete, which is cumbersome, inefficient, and poses certain safety hazards. And during the pouring process, the concrete tanker needs to stay on the inverted arch trestle all the time, that is...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a pouring construction method for tunnel inverts and invert fillings, which is used to solve the problems in the prior art when pouring inverts and invert fillings, such as troublesomeness, low efficiency, potential safety hazards, and passage blockage. The defect that the tunnel construction process is difficult to carry out normally, which affects the tunnel construction speed, ensures the construction speed of the inverted arch and filling and pouring concrete, the operation is simple and fast, and the safety is improved. During the pouring process, the inverted arch trestle can be opened to traffic normally Each process of the tunnel can be constructed continuously without interruption, ensuring the construction speed
