An integrated rainwater sand settling tank device

Abstract

The invention relates to the field of rainwater collection and utilization, in particular to an integrated rainwater sand basin device, which comprises an energy dissipating unit and a sand settling unit, wherein the energy dissipating unit comprises an energy dissipating well; a water inlet pipe is arranged at one side of the energy dissipating well; the sand settling unit comprises a sand basin and a mud collecting groove arranged in the sand basin; the bottom of the energy dissipating well is lower than the bottom of the sand basin; a separating wall is arranged between the energy dissipating well and the sand basin; the energy dissipating well is connected with the sand basin through a flowing port in the separating wall; a water outlet pipe is connected to one end, far away from the energy dissipating well, of the sand basin; the bottom of the sand basin between the separating wall and the mud collecting groove is downwards inclined to the mud collecting groove from the separating wall; a mud discharging pipe for discharging mud and sands outwards is arranged on the bottom part of the mud collecting groove. According to the integrated rainwater sand basin device provided by the invention, the settling efficiency is improved, meanwhile, the obstruction of the flowing port between the energy dissipating well and the sand basin is avoided, the settled mud and sands are directly discharged through the mud collecting groove so as to omit the process of desilting, and the practicability of the device is improved.

Description

technical field [0001] The patent of the present invention relates to the field of rainwater collection and utilization, in particular to an integrated rainwater sedimentation tank device. Background technique [0002] Facing the increasingly severe contradiction between supply and demand of water resources, how to make full and effective use of rainwater resources has become one of the hot topics in the development of water resources in my country. High-speed urbanization and inappropriate urban pattern construction concepts have led to a rapid increase in the number and proportion of impermeable underlying surfaces (the earth's surface that is in direct contact with the lower atmosphere), and the urban heat island effect has become apparent, which has changed the urban rainwater environment and operating laws, resulting in On the one hand, the surface runoff increases and the runoff coefficient increases. On the other hand, the rainwater confluence time shortens, the peak ...
