Device for digging wire conduit under road

Abstract

The invention belongs to the technical field of wire laying equipment and particularly discloses a device for digging a wire conduit under a road. The device for digging the wire conduit under the road comprises a fixing mechanism arranged on one side of the road, a digging mechanism arranged on the fixing mechanism and a control mechanism used for controlling the digging mechanism. According to the invention, the digging mechanism can be arranged on one side of the road, by means of the combination of multiple sections of digging ground augers, on the premise of without slurry pressure maintaining, a road crossing channel is dug under the road, and the structure of the digging equipment is greatly simplified at the same time.

Description

technical field [0001] The invention relates to the technical field of line laying equipment, in particular to a device for excavating conductor pipelines under road surfaces. Background technique [0002] At present, with the expansion of urbanization scale, more and more lines go from the ground to the ground, but there are no underground passages reserved for some road surfaces, which makes it necessary to excavate again, but the existing construction devices are often relatively poorly equipped. Large, it needs to be transported by vehicles during transportation or transportation, which will cause great inconvenience. At the same time, mud must be used for pressure-holding excavation. Therefore, a non-excavation line laying device that can be replaced by small equipment is required. [0003] In the application publication number CN107574836A, a construction structure for crossing the underground passage of urban roads is disclosed, including a first construction structur...

Problems solved by technology

[0004] In the authorized announcement number CN203925283U, a non-excavation horizontal directional drilling rig is disclosed, which relates to the technical field of drilling rigs; It is equipped with a drill frame, a power station assembly, a hydraulic system and an electrical system. The drill frame includes a working slide rail. The drill pipe and the power head device are arranged on the work slide rail. The power head device includes a hydraulic motor, a reduction mechanism, and an operating valve. block, the hydraulic motor drives the deceleration mechanism to run, and at the same time drives the drill pipe to rotate, and the power head device moves forward and backward on the drill frame through the working slide rail; the hydraulic system, electrical system and power station assembly are all set in the drilling rig shell , the power station assembly includes a diesel engine, and the above-mentioned diesel tank is connected to the diesel engine through pipelines; its beneficial effect is that it does not need to dig the ground surface during construction, and pipelines can be laid to cross roads, railways, rivers, etc. The advantages of fast speed and high construction precision; however, the structure of the device is large and complex, and it needs to be transported by vehicles during transportation or transportation, which will cause great inconvenience, and it is necessary to use mud to maintain pressure and excavate
