山塘大坝治理工程施工技术

Construction Technology of Shantang Dam Treatment Project

水库大坝对于人们的生活及工作有着重要的作用,是人们离不开的重要基础设施,如果一旦出现问题,将会产生不可预料的一系列的连锁反应,不但威胁着人们的生命安全,还会造成经济和社会的影响。山塘大坝始建于20世纪五六十年代,经过多年的运行存着一些的问题:大坝上游坝面采用土工膜防渗,经多年的运行,塘内存在一定程度的淤积,其坝基和坝体渗漏严重;大坝上游坝面采用干砌石护坡,淘刷损坏严重。大坝下游坝面为植草护坡,较为规整,但杂草丛生。因此,需要对山塘大坝进行治理,文章详细介绍了山塘大坝治理工程的主要采用的施工技术。

The reservoir dam plays an important role in people’s life and work,and is an important infrastructure that people cannot leave.If there is a problem,it will produce an unpredictable series of chain reactions,not only threatening people’s life safety,but also causing economic and social impact.The Shantang Dam was first built in the 1950 s and 1960 s.After many years of operation,there are some problems.The upstream dam surface of the dam adopts a geotextile membrane for seepage prevention,but after years of operation,there is a certain degree of siltation in the reservoir,and there is severe leakage in the dam foundation and dam body.The upstream dam face of the dam is protected by dry masonry,which is severely damaged by scouring.The downstream dam face of the dam is planted with grass for slope protection,which is relatively regular,but overgrown with weeds.Therefore,it is necessary to control the Shantang Dam.The article introduces in detail the main construction technologies used in the Shantang Dam control project.
