Small pipe diameter drainage pipeline pipe jacking machine tool and pipe jacking construction method

Abstract

The invention relates to a small pipe diameter drainage pipeline pipe jacking machine tool and a pipe jacking construction method, in particular to a two-way roof drawing construction method. The small pipe diameter drainage pipeline pipe jacking machine tool and the pipe jacking construction method are suitable for pipe jacking construction of a drainage pipeline with the pipe diameter being 200-700 mm. The small pipe diameter drainage pipeline pipe jacking machine tool is mainly composed of a directional drill, a directional drill control panel, a pipe jacking machine, a pipe jacking machine control panel, a drill pipe, a drill bit, a reamer, a guide pipe and a slurry system. Pipe jacking construction comprises three steps of drill pipe jacking, counterbore pulling back and guide pipe jacking and pipe section jacking. Drill pipe jacking adopts automatic direction discriminating and automatic deviation correction. Reaming adopts the mode that the front end pulls the rear end to assist jacking and pushing, pulling and jacking and pushing are synchronously conducted, power is coordinated and shared, direction deviation and guide pipe protrusion are not caused in pulling and reaming uplift, the rear-end guide pipe is jacked along the track of the guide pipe which is jacked into soil, jacking force is relatively small, and long-distance jacking can be achieved. The defects that in the prior art, deviation is prone to occurring when a soil outlet pipe is jacked, and protrusion is prone to occurring when a pipeline is jacked are overcome, and the small pipe diameter drainage pipeline pipe jacking machine tool and the pipe jacking construction method adapt to wide soil texture ranges.

Description

technical field [0001] The invention relates to a pipe jacking machine tool and a pipe jacking construction method for a small-diameter drainage pipe, belonging to the field of drainage engineering, and in particular to a construction machine tool and a construction method for a small-diameter drainage pipe. Background technique [0002] Urban drainage is divided into rainwater and sewage. The drainage system is divided into diversion system and combined system. Most cities adopt diversion system, that is, rainwater and sewage are discharged separately. In the early stage of urban construction, the drainage pipes for rain and sewage diversion are generally constructed by open-cut construction. After the pipes are laid, the trenches are backfilled to build roads. There are also many cities that adopted a combined drainage system in the initial stage of urban construction due to factors such as funds, that is, rainwater and sewage are combined and directly discharged into rive...
