Abstract

The invention belongs to the technical field of underground pipeline construction, and discloses a long-distance pipeline laying construction method which comprises the steps of guide hole manufacturing and pipeline back dragging. The guide hole manufacturing comprises the steps that a ground magnetic field is established with a preset pipeline route as the center, and interference of a high-voltage electromagnetic field is eliminated; positioning information based on the ground magnetic field and the pipeline route is obtained through detection guiding control equipment carried on a drill bit drill rod, the positioning information is transmitted back to a ground control terminal, and the drilling angle and direction are controlled based on a received control instruction; and after the guide hole is drilled through, chambering and hole cleaning operations are executed until the guide hole is manufactured. According to the long-distance pipeline laying construction method, stable construction in a high-voltage electromagnetic field area can be guaranteed, and the long-distance pipeline laying construction method can adapt to pipeline back-dragging construction in a small space.

Description

technical field [0001] The invention relates to the technical field of underground pipeline construction, in particular to a long-distance pipeline laying construction method. Background technique [0002] Underground pipeline laying usually adopts the construction method of large surface excavation, but in the case of buildings, pipe networks, wire network dense areas and other places where the surface cannot be excavated, directional drilling construction technology is usually adopted. Conventional directional drilling uses a guide instrument to control the horizontal and vertical positions of the drill hole, and uses wireless to send the position coordinates of the drill bit to the computer control terminal, compares the position of the drill bit with the designed position, and adjusts the position and angle of the drill bit according to the comparison results to ensure that the drilling The location is consistent with the piping design routing. However, when constructio...
