Large-diameter long-distance water transmission pipeline splicing, sinking and placing system and method thereof

Abstract

The invention discloses a large-diameter long-distance water transmission pipeline splicing, sinking and placing system and a method thereof. The system is characterize by comprising controllable floating box devices which are installed on a water transmission pipe and capable of changing the sizes of buoyancy; a support platform which is installed on pipe piles; auxiliary lifting device which is installed on the support platform and is used for assisting to lift, sink and place the water transmission pipe; a command center and a measurement and control mechanism which is used for monitoring the construction process. the measurement and control mechanism sends data to the command center, wherein the measurement and control mechanism comprises a lifting carrying measurement device, a height measurement device and a liquid level measurement device; the lifting carrying measurement device is used for measuring the gravity changes of the water transmission pipe; the height measurement device is used for measuring the height decreased displacement of the water transportation pipe; the liquid level measurement device is used for measuring the height of the water transportation pipe relative to the water surface. The sinking placing system and method of water transmission pipelines have simple construction process, high safety, require less ships, have high adjustability and are convenient for control.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, and specifically refers to a large-diameter long-distance water delivery pipeline splicing and sinking system and a method thereof. Background technique [0002] With the development of science and technology and the improvement of people's living standards, more and more projects are being built to benefit the people, which greatly promotes economic development and facilitates people's lives. In the existing technology, the overall construction plan and process system design plan of the cross-river water pipeline must ensure the control accuracy of piling during the construction process, the installation accuracy of underwater steel structures, and the overall sinking accuracy of the pipeline. In particular, the construction of large-diameter and long-distance water pipes consumes a lot of manpower, material resources, and financial resources, and it must be ensured that ev...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a large-diameter long-distance water pipeline splicing, sinking system and its method, aiming to solve the problem of large-scale lifting ships entering the site due to the constraints of the inland water system, requiring many ships, and long-distance The overall tailor-welding of the pipeline above the water is difficult, and the accuracy of the plane position and elevation during the overall sinking construction requires high precision.
