Problems solved by technology

Since the closing section is on the shore, shipping by sea consumes a lot of manpower and material resources. In addition, the draft is not enough, shipping by sea will cause the collision of the installed and sunk pipelines, resulting in pipeline damage

Abstract

The invention discloses a method for transporting large-diameter and super-long HDPE pipelines into water on land. After the welded pipelines and ballast blocks are poured with concrete in the welding area, the pipelines are directly rolled to the water surface of the foundation groove on the shore construction platform. The transportation distance is shortened, and the transportation process is guaranteed not to collide with the installed pipe section, the required production cost is small, and the operability is high.

Description

technical field [0001] The invention relates to the fields of port engineering, traffic engineering, and water conservancy engineering, and in particular to a method for transporting large-diameter and super-long HDPE pipes from land to water. Background technique [0002] High-density polyethylene pipe (hereinafter referred to as HDPE pipe) is a new type of green and environmentally friendly building material product. It has the advantages of long service life, small fluid resistance and strong corrosion resistance. It is widely used in water supply (leading) water systems, drainage systems and gas transmission. and many other fields. [0003] In the application of HDPE pipe intake and drainage engineering, the transportation and launching of Helong section is the last link of pipeline construction, and its construction technology and construction quality have a great impact on the entire project. When the HDPE pipeline is installed to the final closing section, there are ...
