雨水口篦子泄水量是雨水口泄水能力好坏的关键因素 ,本文通过水工模型试验对不同型式的篦子在不同上游来水流量以及不同纵坡条件下的泄水量做了系统的试验研究 ,最后对雨水口篦子型式的选择提出了推荐方案 ,并对篦子的安装和维护提出了应注意的事项。
The grate discharge of the gully is the key factor of the discharge capacity of the gully. In this paper, the hydraulic model test is conducted to systematically study the discharge of different types of grates at different upstream inflow rates and different longitudinal conditions. At last, the recommended scheme for the selection of the grate type of the grate is put forward. Attention should also be paid to the installation and maintenance of the grate.
