Problems solved by technology

[0002] At present, the concrete pouring construction of subgrade slopes in the fields of international and domestic railways, highways, municipal public roads, and airport roads rely solely on manual reverse transportation and fixed formwork. The formwork is heavy during construction on high slopes, and difficult transportation and installation are difficult. Poor, low work efficiency, cumbersome construction process, the accuracy can not be effectively guaranteed

Abstract

The invention relates to a roadbed slope protection truss trolley and a construction method. The construction method includes steps of (1), preparing for construction and mounting and configuring gears, rollers, motors, jacks, connecting section steel and H-shaped section steel socket systems; (2), mounting fixing frames at positions where formworks need to be fixed; (3), mounting upper and lower ladder stands at two side edges of a truss; (4), arranging cables along the direction of a roadbed line, connecting one end of each cable with the corresponding motor and connecting the other end of each cable with a changeover switch; (5), adjusting the elevations of the formworks and the elevation of the truss under the control of handles of the jacks; (6), adjusting the traveling direction of the truss under the control of the changeover switches. The roadbed slope protection truss trolley and the construction method have the advantages that labor and materials can be saved, the roadbed slope protection truss trolley and the construction method are low in investment and wide in service range, the labor intensity of workers can be reduced, and maintenance can be facilitated.

Description

technical field [0001] The invention belongs to the technical field of fixed formwork installation for railways, highways, municipal roads and airport roads, and particularly relates to a roadbed slope protection truss trolley and a construction method. Background technique [0002] At present, the concrete pouring construction of subgrade slopes in the fields of international and domestic railways, highways, municipal public roads, and airport roads relies solely on manual transportation and fixing of formwork. The formwork is heavy during construction on high slopes, and it is difficult to transport and install and fix the concrete. Poor, low work efficiency, cumbersome construction process, and the accuracy cannot be effectively guaranteed. Contents of the invention [0003] The object of the present invention is to provide a roadbed slope protection truss trolley and a construction method to solve the technical problems existing in the known technology, which can short...
