Abstract

The invention relates to a tunnel second-lining concrete chute pouring system. The tunnel second-lining concrete chute pouring system comprises a tunnel second-lining concrete chute system, a rapid closing structure of a lining formwork pouring window and a tunnel second-lining concrete multi-layer synchronous vibrating device. The tunnel second-lining concrete chute system comprises a main hopper, auxiliary hoppers, an inserting plate, a steel formwork, a fixed sling groove, a movable sliding groove, pouring windows, top supports, lifting supporting rods, a track and a tunnel pavement; the rapid closing structure of the lining formwork pouring window comprises the steel formwork, the pouring windows, hinged lug plates, closing plates, hinged bolt holes, fixed bolt holes and rubber sealingrings; and the tunnel second-lining concrete multi-layer synchronous vibrating device comprises the steel formwork, the pouring windows, bottom beams, trolley portals, a power distribution boxes, networking electric wires, attached flat vibrators, and extension platforms. The tunnel second-lining concrete chute pouring system has the beneficial effects that telescopic flow-dividing tumbling barrels and the lifting supporting rods are adopted, the heights of the sliding grooves can be flexibly adjusted to be suitable for pouring windows with different heights.

Description

technical field [0001] The invention relates to the field of concrete pouring, in particular to a tunnel secondary lining concrete chute pouring system and a construction method. Background technique [0002] At present, our country is in a period of rapid construction and development, and the construction of any project is inseparable from the concrete structure. With the rapid development of my country's high-speed rail and expressways, there are more and more tunnels. In tunnel construction, a lot of concrete needs to be poured for the second lining of the tunnel to ensure the structural stability of the tunnel, that is, to make a ring of concrete lining inside the primary support according to the shape of the tunnel. In the traditional construction of the second lining concrete of the tunnel, it takes time to disassemble the pump pipe, the workers only use a single window for convenience, the pouring window is not closed tightly, and the concrete is not vibrated suffici...
