Automatic distributing system and construction method of single-line tunnel lining trolley

Abstract

The invention discloses an automatic distributing system of a single-line tunnel lining trolley. The system comprises two shaftless spiral conveyors arranged on the trolley, wherein the two shaftlessspiral conveyors are respectively positioned on the upper sections of the left side wall and the right side wall of a tunnel and are arranged in the direction of the two shaftless spiral conveyors; agroup of side wall conveying pipe groups are arranged below each shaftless spiral conveyor; each side wall conveying pipe group comprises a plurality of conveying pipes; each conveying pipe comprisesa vertical pipe which is vertically arranged downwards and a plurality of side wall conveying pipes; the vertical pipe is communicated with a feed opening of the shaftless spiral conveyor; a pluralityof discharge through holes are arranged on the vertical pipe wall at intervals from top to bottom; input ends of a plurality of side wall conveying pipes are correspondingly communicated on the discharge through hole, output ends are arranged corresponding to a side tunnel outwards and corresponding to a lining pouring position of the side tunnel. The distributing device is simple and convenientto install and disassemble, solves the problem of material distribution in a narrow space of the single-line tunnel, reduces the labor intensity, solves the problem that the left side and the right side are not easy to pour simultaneously, and effectively ensures the concrete pouring quality.

Description

technical field [0001] The invention belongs to the technical field of tunnel engineering construction, and in particular relates to an automatic material distribution system and a construction method of a single-line tunnel lining trolley. Background technique [0002] The secondary lining of the tunnel ensures the stability, safety and aesthetics of the tunnel in use, and is also an important engineering measure as a safety reserve. The overall quality of the concrete directly affects the function of the secondary lining. The secondary lining trolley is the main equipment for the secondary lining, and its tooling technology plays a decisive role in the quality of the secondary lining. At present, concrete pouring usually adopts the "single pipe by window" method, that is, after the concrete delivery pump and supporting pipelines are connected, the concrete is poured in accordance with the principle of "bottom to top, one side pouring", and the concrete is adjusted to the w...

Problems solved by technology

At present, concrete pouring usually adopts the "single pipe by window" method, that is, after the concrete delivery pump and supporting pipelines are connected, the concrete is poured according to the principle of "bottom to top, one side pouring", and the concrete is adjusted to enter the window by manual pipe transfer and distribution. The labor intensity of layered and divided warehouses is high, and the pouring time is long and unfavorable to control, which causes "humps" and "cold seams" to appear easily during pouring of concrete, and when the amount of concrete poured on one side is too large, uneven force on the trolley leads to partial occurrence of formwork. Displacement and other phenomena, which will lead to concrete quality problems
