Movable type drilling trolley

Abstract

The invention discloses a movable type drilling trolley which comprises a rear bracket; a front bracket is movably connected with the side face of the rear bracket; a movable drilling machine pointingto the side face of a side ditch is horizontally fixed onto the front bracket; a water tank and a power device are fixed onto the rear bracket and are connected with the movable drilling machine viaa pipeline and a wire separately; and a road wheel is arranged at the bottom of the rear bracket. The movable type drilling trolley has the advantages of being convenient in drilling operation and high in drilling efficiency and drilling precision, can reduce manual input and eliminate a potential safety hazard, greatly reduces the construction cost and shortens the construction period. In addition, according to 4% transverse slope design, pipeline drilling control and precise elevation positioning are realized to ensure smooth water draining.

Description

technical field [0001] The invention relates to a mobile drilling trolley, belonging to the technical field of road construction drilling equipment. Background technique [0002] Water is the main natural factor that endangers roads, and it is also one of the main causes of early damage to asphalt concrete pavement. During the road construction process, in order to prevent the infiltration of rainwater from infiltrating the road surface from invading the pavement base and soil foundation, resulting in the reduction of the strength of the pavement base and soil foundation, when hot asphalt is laid on the top of the base, the gravel seal is synchronized, and gravel blinds are installed at the edge of the road. Ditch, the water infiltrated into the pavement structure layer flows into the gravel blind ditch at the edge due to the slope of the road arch, and the Ф4cm horizontal hard plastic drainage pipe is installed every 20m in the gravel blind ditch, and the seepage water unde...

AI Technical Summary

Problems solved by technology

[0003] Due to the difficulty in constructing gravel blind ditches at the edge of the pavement, and the design dimensions of the excavation section and filling section are inconsistent, the civil engineering unit did not reserve a Ф4cm horizontal hard plastic drainage pipe channel when implementing the side ditch, and due to the height control of the side ditch, the civil engineering unit It is also not convenient to reserve a hole

[0004] At present, it is generally used to construct the Ф4cm drainage pipe channel by fixing the drill with expansion bolts on the side ditch. The construction efficiency of this process is low, mainly because it is labor-intensive to install the expansion bolts, and the expansion bolts are not easy to remove after drilling. The construction of the base layer will affect the rolling of the road roller, which is not convenient for edge compaction, and may damage the road roller
