Water circulation system for speed reduction of test device

The invention discloses a water circulation system for speed reduction of a test device, which comprises a water recovery system and a water injection system which are arranged by virtue of a speed reduction groove, and a deep sedimentation tank for shunting and purifying test water or rainwater is communicated between the water recovery system and the water injection system. The water recycling system comprises a plurality of water collecting pits used for collecting test water and a rainwater well used for collecting rainwater. According to the invention, recycling of water resources is realized, and the water resources are saved. 本发明公开了一种用于试验装置减速的水循环系统，包括依托减速槽设置的水回收系统和注水系统，水回收系统和注水系统之间联通有用于分流、净化试验用水或雨水的深沉池，水回收系统包括多个用于收集试验用水的集水坑和汇流雨水的雨水井。本发明实现了水资源的循环使用，节约了水资源。
