中国是一个水资源缺乏国家,因此,渠道工程显的尤为重要。渠道工程中井点降排水方法的应用,使用人工降低地下水位的方法不仅能够保证渠道等大型基坑的经常性排水需要,而且能够使开挖和渠道衬砌施工一直处于干地上实施。特别是在砾质粘土、重粉质壤土这类地基的习惯性排水施工的时候,利用人工降低地下水位法,就能达到有效的避免由于基坑底面的下沉、坑底与地下水位的落差加大、地下渗水压力作用不断加强而导致的边坡脱滑、坑底隆起等事故的不断出现。本文将对渠道工程中井点降排水方法的应用进行阐述和探讨,以期对类似工程能有参考价值及意义。
China is a country lacking in water resources. Therefore, it is especially important that the channel works clearly. The application of well point descending and drainage method in channel engineering and the method of artificial groundwater table lowering can not only ensure the regular drainage needs of large-scale foundation pit such as channel, but also enable the construction of excavation and canal lining to be conducted on dry land all the time. Especially in the habitat drainage construction such as gravelly clay and heavy silty loam, the artificial groundwater level reduction method can effectively prevent the fall of the pit bottom and the groundwater table due to the sinking of the foundation pit bottom Increase, the role of underground water seepage pressure continued to strengthen and lead to the slippery slope, the end of the pit uplift and other accidents continue to appear. This article will elaborate and discuss the application of well point descending and drainage method in channel engineering in order to have reference value and significance for similar projects.
