Eccentric sand clock type diversion ditch

Abstract

The invention discloses an eccentric sand clock type diversion ditch. The eccentric sand clock type diversion ditch is of a rectangular structure and is composed of a main ditch body (1) and a diversion chamber (6), wherein a water inlet end (2) and a water outlet end (3) are arranged at the two ends of the main ditch body (1), a water-blocking weir plate (4) is arranged at the side close to the water outlet end (3), the water-blocking weir plate (4) and two sides of the main ditch body (1) respectively form a 45-degree included angle, the main ditch body (1) is connected with the diversion chamber (6) through an eccentric sand clock type diversion hole (5), a floating barrel (7) and a floating barrel guide rope (8) are arranged under the eccentric sand clock type diversion hole (5), the floating barrel (7) can move up and down along the floating barrel guide rope (8), and a diversion effluent pipe (9) is arranged at the tail end of the diversion chamber (6). The eccentric sand clock type diversion ditch can not only control all the polluted runoffs caused by light rains and initial runoffs of medium and heavy rains, but also implement partial control in the whole process of runoffs of medium and heavy rains.

Description

technical field [0001] The invention relates to the technical field of urban drainage, in particular to an eccentric hourglass diversion channel for initial rainwater and dry sewage Background technique [0002] The formation of runoff pollutants mainly refers to the leaching, scouring and transportation of pollutants on the catchment surface during the rainfall process, resulting in the accumulation of a large number of pollutants in the runoff. Since the process includes the process of runoff transport, it also involves complex phenomena such as sedimentation, mixing and scouring of runoff in the pipeline system. Generally, the concentration of pollutants in the runoff is the highest at the beginning of the rainfall, and as the rainfall lasts, the concentration of pollutants in the runoff gradually decreases, and finally maintains a low concentration range. [0003] The direct discharge of runoff from urban rainwater pipes has a great impact on the water quality of receiv...

AI Technical Summary

Problems solved by technology

The weir interception method can control the polluted runoff of the rainwater pipeline in the whole process, but the diversion effect and efficiency of the initial rainwater and dry sewage are not very optimistic
