Drilling-grouting integrated equipment and construction method for road base reinforcement

Abstract

The invention discloses drilling-grouting integrated equipment for road base reinforcement. The drilling-grouting integrated equipment comprises an integrated drill boom, an air blowing device, a dustcollection device, a grouting pump and a traveling device. The integrated drill boom comprises an electromagnetic reversing valve, a power head assembly, a hollow drill rod, a hydraulic oil cylinderand a sliding base; the electromagnetic reversing valve is provided with a first inlet end, a second inlet end and an outlet end; the outlet end is connected with the power head assembly, the hollow drill rod is mounted on the power head assembly, and a dust collection cover is arranged at the tail end of the hollow drill rod; and the hydraulic oil cylinder drives the power head assembly to make displacement along the sliding base. The air blowing device is connected with the first inlet end; the dust collection device is connected with the dust collection cover; one end of the grouting pump is connected with slurrying equipment, and the other end of the grouting pump is connected with the second inlet end; the traveling device is used for supporting the integrated drill boom, the air blowing device, the dust collection device and the grouting pump; and through reversing, the electromagnetic reversing valve enables the air blowing device or the grouting pump to communicate with the hollow drill rod. In addition, the invention further discloses a construction method. According to the drilling-grouting integrated equipment for road base reinforcement, drilling and grouting fusion isconvenient to achieve.

Description

technical field [0001] The invention relates to the field of road construction, in particular, the invention relates to an integrated drilling and injection equipment for road base reinforcement and a corresponding construction method. Background technique [0002] The road trenchless grouting reinforcement method is a relatively new road maintenance technology in recent years, which can solve problems such as subsidence, cracks, and potholes in the road. The principle is to first drill the road according to the design requirements, and then inject the grouting material into the cracks and voids of the road structure to reinforce and improve the bearing capacity of the road structure. In the actual on-site construction process, the key processes (drilling and grouting) use their own independent construction equipment for construction operations, which makes the on-site equipment numerous and complicated, which is not conducive to the management of mechanical equipment. In a...

Problems solved by technology

In the actual on-site construction process, the key processes (drilling and grouting) use their own independent construction equipment for construction operations, which makes the on-site equipment numerous and complicated, which is not conducive to the management of mechanical equipment

In addition, the two processes are constructed sequentially, and there is a certain interval in the construction connection time, which has a certain impact on the construction efficiency
