Municipal rainwater drainage system not prone to blockage and rainwater drainage method
The invention relates to the technical field of municipal rainwater drainage, in particular to a municipal rainwater drainage system not prone to blockage, which comprises an inspection well vertically buried underground and a sewage drainage pipeline spaced from the bottom of the inspection well by a certain distance, the sewage drainage pipeline is used for rainwater to flow into a river channel, and a wellhead is fixed at the top of the inspection well. A lower blocking device is arranged at the bottom of the inspection well, an upper blocking device is arranged at the position, at the top of the lower blocking device, in the inspection well, the upper end of the upper blocking device is larger than the lower end of the upper blocking device, and the upper end of the lower blocking device is larger than the lower end of the lower blocking device. The upper blocking device and the lower blocking device are installed in the inspection well, the cavity for water to flow through is formed between the upper blocking device and the inspection well and between the lower blocking device and the inspection well, then silt is collected in the upper blocking device, and it is avoided that too much silt is accumulated at the bottom of the inspection well, and consequently a blow-off pipeline is blocked.
本发明涉及市政雨水排泄技术领域，具体是涉及一种不易堵塞的市政雨水排泄系统，包括有竖直埋在地下的检查井和与检查井底部相距一端距离的排污管道，所述排污管道用于雨水流入至河道中，所述检查井顶部固定有井口，所述检查井的底部设置有下阻拦装置，所述检查井内部设置在下阻拦装置顶部的位置设置有上阻拦装置，所述上阻拦装置的上端大于上阻拦装置的下端，所述下阻拦装置的上端大于下阻拦装置的下端，本发明通过在检查井中安装有上阻拦装置和下阻拦装置，上阻拦装置和下阻拦装置与检查井之间形成供水流过的空腔，进而泥沙被收集在上阻拦装置中，避免检查井底部的泥沙堆积过多，进而堵塞排污管道。
