Embodiment approach

[0036] As a specific embodiment of the present invention, the rotating plate 111 is composed of several hollow tubes 116 and a T-shaped block 117; several hollow tubes 116 are fixed side by side on the bottom of the T-shaped block 117; the hollow tubes 116 have free ports. There is a leaking net 118 to prevent larger particles of rubbish from entering the hollow tube 116; during use, when the cross-sectional area and length are all the same, the solid rod is made into a hollow tube 116 with an internal and external diameter of 8:11, which can effectively improve the hollow tube. The intensity of 116, the hollow tube 116 that is arranged side by side forms rotating plate 111, has improved the torsional moment bearing capacity of rotating plate 111 on the one hand, has improved the strength of rotating plate 111, and on the other hand hollow tube 116 that is arranged side by side forms rotating plate 111, When the rotating plate 111 is damaged, it is only necessary to replace the...

Abstract

The invention relates to the technical field of municipal roads, in particular to a municipal roadbed construction method. The method comprises the steps that S1, garbage is removed through a road sweeper, then the surface of a foundation is leveled, and the foundation is repeatedly rolled through a road roller until the strength of the foundation meets the requirement; S2, a bottom-layer soil base is buried firstly, then a functional soil base is buried, and finally a pavement is built; and S3, drainage ditches are laid, net covers are installed at the tops of drainage grooves at the two sides of the pavement, and garbage is prevented from falling into the drainage grooves and being blocked. A rotating plate formed by arranging a plurality of hollow pipes and T-shaped blocks is used for replacing a rotating plate in a sweeping device of the road sweeper, the strength of the rotating plate is improved, the stability of the rotating plate is enhanced through the action of a first elastic rod and a steel cable, and water is poured into the hollow pipes through arrangement of a cam, a second elastic rod, a third elastic rod and a piston. Water columns are used for eliminating partialpressure in the hollow pipes, the strength of the hollow pipes is improved, through the design, the strength of the rotating plate of the sweeping device is improved, and the breaking condition of therotating plate is reduced.

Description

technical field [0001] The invention relates to the technical field of municipal roads, in particular to a municipal roadbed construction method. Background technique [0002] Municipal Road Subgrade Requirements Today, as the pace of life continues to accelerate, convenient transportation is particularly important, which puts forward higher requirements for municipal road engineering, and the subgrade as the main body of the road cannot be ignored. In addition, the roadbed project has the characteristics of a large number of projects and a wide range of areas. Therefore, timely and correct cleaning of the garbage generated by the roadbed plays a vital role in improving the quality of municipal road projects, speeding up the progress of the project, and ensuring the normal use of the project. , the road construction purging machine is mainly suitable for cleaning the surface of the roadbed in the process of expressway, municipal construction and road and bridge construction....
