Highway roadbed abutment backfilling gravel inverted filter layer pavement device

Abstract

The invention provides a highway roadbed abutment backfilling gravel inverted filter layer pavement device. A main frame, a bottom plate, a hopper, a flow guiding pipe, a limiter, a flow adjusting plate, walking wheels and a sieve plate are included. The main frame is arranged above the bottom plate and comprises a main framework and a balance frame. The hopper is arranged on the main frame. The walking wheels are arranged at the bottom of the bottom plate. The flow guiding pipe is arranged at the bottom of the hopper. The flow guiding pipe comprises a vertical pipe, a corner and an inclined pipe from top to bottom. A notch is formed in the side portion of the vertical pipe. The flow adjusting plate is inserted in the notch, falling material flow is adjusted through drawing, and the corneris connected with the vertical pipe and the inclined pipe. The outlet end of the inclined pipe is arranged on the right side of the bottom plate. The sieve plate is arranged in the hopper and provided with a plurality of sieve holes. The limiter comprises a longitudinal limiting plate and a transverse limiting plate, and is fixed to the right side of the main frame through a clamping piece. The highway roadbed abutment backfilling gravel inverted filter layer pavement device is simple in structure and convenient to disassemble and assemble, pavement materials are subjected to pavement throughthe limiter, and the effect is conveniently achieved.

Description

technical field [0001] The invention belongs to the technical field of road construction equipment, and in particular relates to a paving device for backfilling a gravel reverse filter layer on the back of a road bed abutment. Background technique [0002] In the process of highway construction, it is necessary to monitor the paving quality of the backfill anti-filter layer on the back of the roadbed under construction. At present, the commonly used method is to pave manually with shovels, which consumes relatively high labor costs, and the construction of workers is relatively random. Large, it is difficult to ensure the thickness and width of the pavement during the construction process. There are many super-sized materials in the material, and workers may not be able to clean up all the super-sized materials. The unqualified materials and construction specifications lead to construction failures. If the quality of the reverse filter layer is unqualified, it will affect th...

[0002] In the process of highway construction, it is necessary to monitor the paving quality of the backfill anti-filter layer on the back of the roadbed under construction. At present, the commonly used method is to pave manually with shovels, which consumes relatively high labor costs, and the construction of workers is relatively random. Large, it is difficult to ensure the thickness and width of the pavement during the construction process. There are many super-sized materials in the material, and workers may not be able to clean up all the super-sized materials. The unqualified materials and construction specifications lead to construction failures. If the quality of the reverse filter layer is unqualified, it will affect the overall drainage function of the subgrade
