Abstract

The invention is applicable to the technical field of pipe network configuration and optimization, and provides a water drainage pipe network configuration and optimization method and terminal equipment. The method comprises the steps of determining the slope range of a water drainage pipe according to a preset maximal design fullness, the set minimum value of the central included angle of the water surface and the water drainage pipe, the flow value of the water drainage pipe and the pipe diameter value of the water drainage pipe, and then determining the range of the water flow velocity of the water drainage pipe; then adjusting the central included angle of the water surface and the water drainage pipe till the determined water flow velocity of the water drainage pipe satisfies a preset water flow velocity constraint condition, wherein the slope range corresponding to the range of the central included angle of the water surface and the water drainage pipe is the slope value range after water drainage pipe network configuration and optimization. By studying the possible range of the pipe diameter in the configuration and optimization design process, the searching range of the configuration and optimization process is reduced, and the calculation amount in the water drainage pipe network configuration and optimization process is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of pipe network layout optimization, and in particular relates to a drainage pipe network layout optimization method and terminal equipment. Background technique [0002] With the continuous acceleration of the urbanization process in our country, the drainage pipe network as the urban infrastructure is also particularly important. After the flow rate of the drainage pipe is determined, the diameter and slope of the drainage pipe have a variety of combinations that meet the conditions. The selection of different pipe diameter values ​​and slope values ​​directly affects the cost of pipe materials and construction costs. Therefore, whether the optimal design method of drainage pipe network layout is reasonable or not directly affects the cost of drainage pipe network and subsequent maintenance costs. In the process of realizing the present invention, the inventors found that the existing drainage pipe networ...
