Abstract

The invention provides a concrete distributor for a tunnel formwork trolley. The concrete distributor comprises a distributor base, wherein a main pipeline support, an S pipe front bracket, an S piperotary bracket and a sub-pipe sliding seat assembly are arranged on the distributor base; a main pipeline is arranged on the main pipeline support; S1 pipelines are arranged on the S pipe front bracket and the S pipe rotary bracket; a sliding distribution slider assembly and a sliding oil cylinder rear seat are arranged on the sub-pipe sliding seat assembly; a sliding oil cylinder is arranged between the distribution slider assembly and the sliding oil cylinder rear seat; the main pipeline is connected with the S1 pipeline; the S1 pipeline is connected with an S2 pipeline; and the S2 pipelineis connected with the distribution slider assembly. The concrete distributor provided by the invention has the following advantages: the structure is reasonable, and the operation is convenient; a pipeline is adopted for pumping during concrete pouring, and thus the pouring is fast; since the concrete is placed in a closed pipeline, the time of contact with air is reduced, the concrete quality isguaranteed, the control for the concrete pouring process is facilitated in tunnel secondary lining construction, and the construction efficiency and the lining quality are improved.

Description

technical field [0001] The invention relates to the field of tunnel lining construction, in particular to a concrete distributor for a tunnel formwork trolley. Background technique [0002] As the geological conditions of tunnel construction become more and more complex, the quality requirements of the secondary lining are getting higher and higher. The traditional tunnel formwork trolley secondary lining concrete pouring adopts the distribution hopper and chute method. After the concrete is divided from the distribution hopper, it flows into the operation window of the formwork trolley through the chute under the action of its own weight. This method is slow in pouring speed and low in construction efficiency. The chute structure It is open, and the concrete is in contact with the air for a long time, so the quality of the concrete is difficult to guarantee, thus affecting the construction quality of the secondary lining. Contents of the invention [0003] The invention ...
