Symmetrical synchronous layered distributing and casting system and construction method for open trench tunnel lining

Abstract

The invention discloses a symmetrical synchronous layered distributing and casting system for an open trench tunnel lining. The symmetrical synchronous layered distributing and casting system for theopen trench tunnel lining comprises a central aggregate groove, multiple casting tumbling barrels, multiple silos, aggregate funnels and multiple distributing sliding chutes, wherein the central aggregate groove is fixed to the center of a lining formwork arch apex and is provided with multiple independent discharge holes; the multiple casting tumbling barrels are fixed into a lining side wall atintervals; the multiple silos are arranged in a layered way; the aggregate funnels are in one-to-one correspondence to the casting tumbling barrels; the lower end ports of the aggregate funnels communicate with the upper end ports of the casting tumbling barrels; the multiple distributing sliding chutes correspond to the multiple discharge holes; and the lower ends of the distributing sliding chutes are located at upper openings of the aggregate funnels or located at distributing trough ports of the silos located on one same layer. The invention further discloses a symmetrical synchronous layered distributing and casting construction method for the open trench tunnel lining. The symmetrical synchronous layered distributing and casting system and the symmetrical synchronous layered distributing and casting construction method for the open trench tunnel lining provided by the invention have the advantages of high construction efficiency, simplicity in operation, reduction in labor intensity, capability of realizing semi-automatic casting, cleanliness in construction due to no concrete drop on site, environment protection without pollution, and the like.

Description

technical field [0001] The invention relates to the technical field of lining pouring for open-cut tunnels. More specifically, the invention relates to a symmetrical and synchronous layered material distribution pouring system and construction method for the lining of an open-cut tunnel. Background technique [0002] In shallow-buried tunnels such as highways, railways, and municipalities, the open-cut method has the advantages of simple technology, fast economy, and easy control of construction quality, so it is often used as the main method for shallow-buried tunnel construction. The open cut method is not only safe and efficient, but also can effectively avoid the secondary lining void and insufficient thickness of the secondary lining. [0003] Although the open-cut method has the above advantages, in the lining construction of the open-cut tunnel, the concrete distribution is often unreasonable or single-point distribution, and the quality of the lining pouring has alw...
