Underground pipeline installation construction device and method thereof

Abstract

The invention discloses an underground pipeline installation construction device and a method thereof. The device is characterized in that baffles are arranged at both sides and at the front end of a box; openings are arranged at the rear end and at the upper part of the box; baffles are arranged on the position which is at the bottom end of the box and is 1 / 2 away from the front end of the box; a hydraulic cylinder is connected with the front end of the box and the other end of the hydraulic cylinder is connected with a thrust stand; one end of a pulling rope is connected in front of the box and the other end thereof is connected with a pulling facility. The method is as follows: a hole is dug on the starting point of an underground pipeline, in which the box is arranged; paddings are backfilled from the upper part to the bottom of the box, the pipeline is hoisted into the box by hoisting equipment from the upper part of the box and is positioned on bedding, and then stones are filled; holes at the front end of the box are dug and pulling equipment is started to move; a bedding layer is filled from the upper part of the box, a secondary pipeline is hoisted, the hydraulic cylinder is started after the secondary pipeline is in place, the pipeline and the secondary pipeline are jointed by a socket, stones are backfilled in the secondary pipeline from the upper part of the box after socket joint and the box is pulled to move; construction installation of a nth pipeline is carried out by cycling the above steps. In the invention, box operation is adopted for stepping pipeline installation, thus ensuring simple working procedures, few links and low cost, greatly increasing the efficiency of underground pipeline installation construction and laying a foundation for realizing full automation of underground pipeline installation construction.

Description

technical field [0001] The invention relates to an underground pipeline installation and construction facility and a method thereof, in particular to an underground pipeline installation and construction device and an installation and construction method thereof which are used for excavation in a rich groundwater and soft soil layers that are prone to collapse. Background technique [0002] For the construction and installation of large-scale pipelines in areas with existing soft soil layers, grading and large openings are used for excavation or excavation after pre-stretching steel plate supporting piles. During excavation, the construction scope of the excavation varies according to the type of the pipeline to be installed. The diameter of the large pipeline is more than 1800mm. Generally, the underground installation pipeline is deep. When excavating with large openings, multiple sets of earthwork are required for excavation. Excavation of mechanical equipment, hoisting o...
