According to the problems of WZ-C bell-less top charging equipment such as high temperature and perviousness of distributor.The causes are analyzed.The water cooling and block system are modified.

针对高WZ-C钟顶装设备存在的布器温高、透水等问题进行了原分析,并进行水冷、水封系统改进。

The maximum depth of the pit is mainly related to the inflow angle, unit discharge and the perviousness of the dike etc. with the maximum impact from the Unit discharge.

透水桩坝的坝前最大冲刷坑要与来流单宽流量、入流角、桩坝透水率等素有关，其中单宽流量对冲刷坑的影响最大。
