The invention relates to pipeline installation and construction technology, in particular to a construction method for installing large-diameter pipelines using cableways in complex terrain in mountainous areas. The invention solves the problems of long construction period, high construction labor intensity, great damage to the local vegetation environment and difficult construction under the complex terrain conditions of mountainous areas in the traditional long-distance and large-diameter pipeline installation and construction technology. The construction method of installing large-diameter pipelines by cableways is used in complex mountainous terrain. Fixed pulley, load-bearing cable, load-bearing saddle, traction cable, two lifting fixed pulleys, counterweight, lifting pulley, lifting cable, hook; b. Lifting of pipe joints; c. Placement of pipe joints ; d. Group pairs of pipe joints. The invention is suitable for the installation and construction of long-distance and large-diameter pipelines under complex terrain conditions in mountainous areas.
Description
technical field [0001] The invention relates to pipeline installation and construction technology, in particular to a construction method for installing large-diameter pipelines using cableways in complex terrain in mountainous areas. Background technique [0002] The installation and construction of long-distance large-diameter pipelines is an important infrastructure project in the fields of municipal and water conservancy. The traditional installation and construction of long-distance and large-diameter pipelines is mainly realized by the following technologies: First, the transportation of pipe joints is completed by means of mules and horses, ground trailer transportation, winch rail transportation, and cloth truck hoisting. Then, the positioning and pairing of the pipe joints are completed by means of pipe laying by crane and pairing of trolleys. Practice shows that the traditional long-distance large-diameter pipeline installation and construction technology has the ...
