Title:
METHOD FOR SETTING WATER INFLOW SECTION OF ONSHORE TRANSPORTATION TRACK FOR LARGE-DIAMETER ULTRA-LONG HDPE PIPE
Document Type and Number:
WIPO Patent Application WO/2021/232483
Kind Code:
A1
Abstract:
A method for setting a water inflow section of an onshore transportation track for a large-diameter ultra-long HDPE pipe, comprising the following steps: determining the total length of a transportation track (100), the length of the track of a water inflow section (130) being 1/12 of the total length of the transportation track (100); determining a load on a pipe (200) according to the weight of the pipe and the weight of fittings, a buoyant force of a water inflow end of the pipe (200), and a traction force of a front end of the pipe (200); determining a dry boundary condition and a wet boundary condition; establishing a model to calculate and analyze the force of the pipe when entering the water; and determining the slope of the transportation track of the water inflow section according to different slope ratio combinations. According to the method, safe and efficient transportation of a pipe is ensured, the engineering amount of a transportation system is also reduced, and thus time and economic costs are saved.
