Roadbed repairing equipment for road construction and construction method thereof

Abstract

The invention relates to roadbed repairing equipment for road construction and a construction method thereof. The equipment comprises a limiting frame, a suction pump, an air compressor, a slurry pipe, an inserting sleeve and a rotating mechanism, the limiting frame is of a semi-annular structure. Pulp pipes are distributed at the inner ends of the limiting frames; threaded holes are symmetricallyformed in the outer side surface of the lower end of the pulp pipes; the upper end of the inserting sleeve sleeves the lower end of the pulp pipes; round holes are formed in the positions, corresponding to the threaded holes of the pulp pipes, of the inserting sleeves, the inserting sleeves are locked in the threaded holes in the lower end of the pulp pipes through countersunk bolts, a rotating mechanism is installed in the upper ends of the pulp pipes, a suction pump is installed on a limiting frame at the right ends of the pulp pipes, and an air compressor is located on the rear side of thesuction pump and installed on the limiting frame at the right ends of the pulp pipes. The problems that when cement paste is poured into a piling hole to reinforce a soft soil roadbed in the prior art, the pressure is small, the seepage force of the cement paste is poor, and therefore the reinforcing range of the outer side of the piling hole of the soft soil roadbed is small can be solved.

Description

technical field [0001] The invention relates to the technical field of road maintenance, in particular to roadbed repair equipment and a construction method for road construction. Background technique [0002] The subgrade is the foundation of the road surface. The main function of the subgrade is to provide the necessary conditions for traffic operation. The subgrade can bear the static load and dynamic load of the traffic load, and at the same time transmit and spread the load to the depth of the foundation. Therefore, the construction quality of the subgrade directly affects the quality of the road. service life. [0003] The roadbed is a geotechnical structure formed by excavation or filling. When the soil of the roadbed is soft soil and the soft soil roadbed is not treated, the road will crack or even be sheared due to excessive settlement, so the soft soil roadbed needs to be reinforced. Treatment, the most commonly used reinforcement method for soft soil subgrade is ...

AI Technical Summary

Problems solved by technology

[0004] 1. When the cement slurry is poured into the piling hole, the pressure is small, which makes the penetration of the cement slurry poor, so the reinforcement range outside the piling hole of the soft soil subgrade is small;

[0005] 2. When the grouting pipe is inserted into the soft soil subgrade, it may be inclined, and the grouting of the piling holes of the soft soil subgrade is not uniform, thus affecting its reinforcement effect
