Description

Trestle convenient to invert layer and filling layer concrete distribution

Technical Field

The utility model relates to a tunnel invert layer and filling layer construction equipment especially relate to a landing stage convenient to invert layer and filling layer concrete cloth.

Background

In the tunnel construction at present, the level of mechanized construction is higher and higher, and the process organization in each area is relatively professional. In an inverted arch concrete filling construction area, the popularization and the use of the self-propelled inverted arch trestle ensure that the construction in the area is safer and more efficient; the popularization and the use of the integral inverted arch template realize the rapid construction of the inverted arch, save the assembly and the disassembly of the template, greatly reduce the labor intensity of workers and improve the construction efficiency and the quality of the inverted arch. The combination of self-propelled invert trestle and integral invert template has satisfied mechanized, automatic, universalization, the standardized demand of tunnel invert construction, has improved efficiency, has practiced thrift the cost. When the concrete pouring construction of the inverted arch layer and the filling layer is carried out at present, the concrete tank truck stops on the trestle for discharging, and concrete flows to a position to be poured by self weight through the simple chute. Pouring in different areas is realized by stopping the concrete tank truck at different positions on the trestle and adjusting the length of the chute. The pouring process is completed manually, the operation environment is very severe, the physical health of workers can be affected, meanwhile, the construction efficiency of manual operation is low, and the construction speed is low. Particularly, when the concrete tank car is poured, the trestle is limited by the self-bearing capacity due to single-lane traffic, so that the smooth construction of other areas is influenced by other engineering vehicles and construction equipment passing through the trestle; meanwhile, when pouring is carried out at each time, only one concrete tank truck can be stopped on the trestle, a plurality of tank trucks cannot be used for pouring simultaneously, and the total integral pouring time is long.
