摘要
马鞍山西梁山水厂一期工程作为重要的供水工程,要求在工程建设时,必须把防洪、行洪当作重中之重。由于该供水工程水泵房及栈桥基础较深,在汛期高水头作用下,容易造成渗透破坏,造成泵房及栈桥基础位置河床冲刷。因此,为保护江堤防洪安全,针对现存问题采取防渗加固措施。通过运行观测,堤后渗透比降至允许范围。
As an important water supply project,the first-stage project of Xiliangshan water plant in Maanshan City is demanded for must placing flood control and flood releasing in top priority position.Because both the foundation of pump room and jetty are deep,during flood period,under the action of high water pressure,soil seepage damage easily takes place,resulting in river bed is scoured at the foundation of pump room and jetty.Therefore in order to guard the safety of river bank,seepage prevention and reinforcement measures were taken aiming at the problems exist.Through operation observation,the osmosis ratios at embankment back have reduced to allowable range.
