In-situ communicating method of beheaded river

Abstract

The invention discloses an in-situ communicating method of a beheaded river. A topology diversion wall is arranged in the center position of the beheaded river with a width of B; one end of the diversion wall is started from the position B / 2 away from the end of the beheaded river, and the other end is connected with a main river channel bank wall; and the diversion wall is higher than a highest level line of a river channel. The in-situ communicating method arranges the topology diversion wall, and changes the main river channel and the beheaded river from a traditional 4-point 3-line topology structure to a 2-point 1-line topology structure, so that water currents flow on the topology structure of one through line, and the communicating running water of a main river and the beheaded river is realized. The in-situ communicating method of the beheaded river is simple and feasible, is excellent in communicating effect, saves the engineering investment, is short in construction period, is low in operation and maintenance costs, and has the popularization and application prospect.

Description

technical field [0001] The invention relates to a method for connecting running water of Duantou River in urban built-up areas. Background technique [0002] The task of urban river water environment management is very heavy, and connecting the Duantou River to achieve smooth flow of water is one of the extremely important governance measures. At present, the methods for connecting the Duantou River to running water mainly include the following: one is to connect the Duantou River with other Duantou Rivers (or other main rivers); the other is to connect the Duantou River with the Laying pipelines and constructing pumping stations between other Duantou Rivers (or other main rivers) to achieve connectivity (see the literature "Application and Analysis of Pipe Jacking Technology in Duantoubang Opening Project", [J] Water Science and Technology, 2013 04); the third is to inject water into the pumping station. The water inlet of the diversion pumping station is placed upstream o...
