雨水井篦是雨水排除系统构筑物之一,它的主要作用是排除城市街道、居民区和工业区路面的雨水。各地安装的雨水井篦尚无标准参数,无论是外型尺寸还是篦孔面积都有很大差别(指在条件相类似的情况下)。不注意一定安装形式的外型尺寸及篦孔过小都会使雨水篦的泄水能力降低,这是某些城市在雨季造成街道淹水的原因之一。苏联某学院对雨水井篦的研究成果可为借鉴。一、雨水井篦的安装形式及其泄流量
The rainwater well is one of the structures of the rainwater drainage system. Its main function is to eliminate rainwater on the pavements of city streets, residential areas and industrial areas. There are no standard parameters for the rainwater wells installed in various locations, and there is a great difference between the external dimensions and the borehole area (in the case of similar conditions). Failure to pay attention to the dimensions of a certain type of installation and the small size of the borehole will reduce the ability of rainwater to drain, which is one of the causes of flooding in certain cities during the rainy season. The research results of a Soviet Union Academy on rainwater wells can be used as reference. I. Installation mode of rainwater wells and their discharge flow
