黑茨河鹿邑县施工段,地层属第四纪全新世,为松散沉积物,土质上层多为砂礓黑土,含有少量粘土和砂壤土,以下是细砂,再下是粘土不透水层。8.565公里施工段中有5.765公里的流砂层,一般在设计河底下1米以上,最高达设计河底以上1.2米。为了充分发挥机械的作用,圆满完成黑茨河治理土方施工任务,鹿邑县黑茨河治理工程指挥部采用塑料管井直线井群这项新技术,成功地降低了地下水位,工程施工进度快、质量高,获得了较高的经济效益。
Heihe River Luyi County construction section, the formation belongs to the Quaternary Holocene, as loose sediments, the upper layer of soil mostly sand grits black clay, containing a small amount of clay and sandy loam, the following is a fine sand, then under the clay impermeable layer. 8.565 km There are 5.765 km of runoff sand in the construction section, which is usually more than 1 meter above the designed river and up to 1.2 meters above the designed river bottom. In order to give full play to the role of machinery, the successful completion of the Heizi River earthworks construction tasks, Luyi County Heizi River Control Engineering Headquarters using plastic tube straight well group this new technology, successfully reducing the water table, construction progress fast, High quality, access to a higher economic benefits.
