Large diameter pipeline winter construction equipment and method thereof

Abstract

The invention relates to a pipeline construction equipment and a method thereof, in particular to a large diameter pipeline winter construction equipment and a method thereof. The construction equipment comprise a traction machine, a cable wire, a fast tightening mechanism, a gate box, a motor, a speed changer and a cable wire fixing rack, wherein the fast tightening mechanism (5) is formed by three symmetrical same anchoring blocks (12), and a hand wheel (10) is arranged on the fast tightening mechanism. The construction method comprises the steps of: installing an assembled fixed pipe (1) and a pipe (2) to be assembled; scrolling the cable wire (4) by using the traction machine (3); respectively using the fast tightening mechanism (5) to firmly fix the scrolled the cable wire (4) and one end of the cable wire at the end parts of the assembled fixed pipe and the pipe to be assembled; leading the installed pipes to be in place, and then tensioning by a sealing ring at the joint part to complete the connection; and leading constructors to move into a next pipe to be assembled, and repeating the process. The invention adopts a set of installation method with convenient operation for the construction in the pipe, has simple construction equipment, and only uses the simple traction machine and the fast tightening mechanism to replace the original excavator or loading machine.

Description

technical field [0001] The invention relates to pipeline construction equipment and a method thereof, in particular to a large-diameter pipeline winter construction equipment and a method thereof. Background technique [0002] Northeast my country, Northwest China, North China (hereinafter referred to as the "Three Norths") and Inner Mongolia have a cold winter climate, and the winter temperature in some areas is around -25°C to -35°C, causing many projects to fail to proceed normally during the long winter. In order to complete some important engineering projects, construction had to be carried out under harsh conditions, as shown in the picture. The construction personnel work in the harsh environment, and the work efficiency and project quality are obviously reduced, which seriously affects the construction process. Through the investigation, we learned that the temperature in the Three Norths of my country and Inner Mongolia is low in winter, and there are many windy an...

The construction personnel work in the harsh environment, the work efficiency and project quality are obviously reduced, which seriously affects the construction process

Through the investigation, we learned that the temperature in the Three Norths of my country and Inner Mongolia is low in winter, and there are many windy and snowy weathers. In the northwest region, where the winter is low temperature and windy and sandy, the construction unit must be equipped with windproof sheds and insulation quilts to protect the operators from the influence of wind and snow. It is necessary to prepare all kinds of safety protection facilities. In the event of severe weather such as strong wind, rain, snow, etc., outdoor operations have to be stopped, and effective anti-freezing and anti-skid measures can be taken before construction. Working in these environments will not only suffer for workers, but also for workers. Moreover, the cost of the project is also greatly increased, and the quality of the project cannot be effectively guaranteed.
