Background

At present, the city realizes the large-scale supply of city natural gas, but the rural natural gas supply has a large vacancy, and the countryside gas construction projects are responded actively in various places, wherein the most important step in the rural gas construction is the construction of a gas pipeline. According to the technical guide of rural pipeline natural gas engineering, when buried laying is adopted, the minimum soil covering thickness from the top of a gas pipeline to the ground is in accordance with the following regulations: when the vehicle is buried under a hard lane, the distance is not less than 0.9 m; when the cable is buried under a place (including a sidewalk) where a motor vehicle is not easy to reach, the distance is not less than 0.6 m; when the soil is buried under the soil road, the buried depth is increased or protective measures such as pressure break prevention, damage prevention and the like are taken.

The existing method for burying the pipeline is to firstly use a ditcher to ditch the pipeline and then place the pipeline in the ditch for laying. However, the following problems still exist in the ditching process at present:

1. the hydraulic motor and the cutting disc in the existing ditcher are coaxially arranged, so that only the part with less than half of the diameter of the cutting disc plays a role during ditching, and the ditching depth is shallow.

2. A deeper channel is required to be formed, only a cutting disc with a larger diameter is adopted, and thus the weight of the machine head is increased, and a walking mechanism with a larger volume is required to keep balance; the traveling mechanism of the ditcher is large in size, so that the ditcher cannot safely travel on most narrow roads in rural areas, the operation range of the ditcher is limited, and the construction efficiency of a channel is influenced.
