利用组合井开发河道潜流

以往河道截潜工程常采用的河边大口井、廊道井、拦河坝等措施,存在着投入人力、物力、财力多等弊端,且施工技术复杂,工期长,受益慢,又妨碍行洪安全。为此,提出利用组合井代潜截潜工程。其基本设想是在河床内布设多眼机孔,在岸边适当位置建设泵站,泵站与各井用管道连接,实现井站联合开发潜流。经过反复论证,确认该方法是一个费省效宏、安全可靠、切实可行的开发方案。

Development of River Subsurface Flow by Using of integrated Wells

In the past, the river subsurface flow intercepting works were the river side large opening well, corridor well and river cross dam. The disadvantages of the works are high costing, more material and labour consuming, complex con- struction technology, long construction period, later benefits and block of flood passing. This paper developed a integrated wells for river subsurface flow intercepting. The main idea is placing many wells in the river bed, constructing pumping station on the river bank, and connecting the wells and pumping station by pipe line. The practice has proved that the de- veloped method is a cost saving, more benefit, safty and reliable measure.
