Automatic paving device for geotechnical materials

Abstract

The invention discloses an automatic paving device for geotechnical materials. The device comprises a walking machine, a connecting mechanism, a paving frame, a compacting mechanism arranged on the rear side of the paving frame, an automatic paving mechanism arranged on the paving frame and an impurity discharging rubber pad arranged below the front side of the paving frame. The connecting mechanism comprises a fixing frame, a rocker arm and a plurality of obliquely-arranged supporting oil cylinders. The compacting mechanism comprises a plurality of adjusting combinations, a transverse steel plate and a compacting rubber pad; the automatic paving mechanism comprises a rotating shaft and a plurality of transmission combinations, the two ends of the rotating shaft are supported on the two sides of the paving frame respectively, and the transmission combinations are arranged on a plurality of oblique beams of the paving frame respectively and comprise motors, driving wheels and driven wheels. The whole laying process is mechanized in construction, a plurality of rolls of geotechnical materials can be installed according to the length of an operation face, continuous operation can be achieved without pause and replacement in the laying process, the walking machine can walk on various terrains, the laying requirement of the complex environment is met, and normal laying can be conducted on a road section with a large longitudinal slope.

Description

technical field [0001] The invention relates to a paving device for geotechnical materials on road subgrade pavement, in particular to a time-saving and labor-saving automatic paving device for geotechnical materials, which belongs to the technical field of road construction equipment. Background technique [0002] With the rapid development of the country's economy, the transportation industry has also been vigorously developed. The existing expressways are increasingly unsuitable for the passage of modern transportation vehicles, and there are more and more expressway or national road reconstruction and expansion projects. During reconstruction and expansion, since uneven settlement easily occurs at the overlap between the old and new subgrades and the pavement, reflection cracks will appear on the pavement, which will affect the driving quality. Therefore, a layer or Multi-layer geosynthetics, geosynthetics have excellent properties such as reinforcement, crack resistance...

Problems solved by technology

[0003] At present, the laying of geotechnical materials either relies on manual paving or simple auxiliary tools. Before laying the above two methods, it is necessary to manually clean the subgrade base on the working surface to remove the sundries on the subgrade base. The entire laying process is manual paving operation, which requires a lot of manual cooperation to complete the laying. Not only is the labor intensity high, the work efficiency is low, the construction speed is slow, and the cost is virtually increased, but also the paving materials are uneven after laying, and the geotechnical materials There are many problems such as poor fit with the base layer, poor laying linearity, and easy secondary pollution during the laying process of the base layer. The quality of the laying is very worrying, which seriously affects the construction quality and construction progress.

In addition, manual or auxiliary tool laying can only be laid on a single roll. After a roll is paved, it needs to be stopped and replaced to continue laying. Continuous operation cannot be realized. It is even more difficult to lay on roads with large longitudinal slopes, and sometimes it is impossible to lay at all.
