Method for preventing salt water invasion of shallow aquifer in estuary area by improving gate structure
The invention discloses a method for preventing salt water invasion of a shallow aquifer in an estuary area by improving a gate structure. According to hydrogeological data of an estuary region, a river shallow aquifer salt water invasion numerical model is established, and under the conditions of considering engineering investment and ensuring building structure safety, the optimal gate downward extension depth is determined, so that the effect of remarkably reducing shallow aquifer salt water invasion is achieved; holes are downwards formed in the gate bottom plate in the gate groove direction, so that the improved gate can enter a water-bearing layer on the lower portion of the gate bottom plate, porous retaining walls are arranged on the upstream, the downstream and the two sides of the water-bearing layer of the gate, a cavity structure without porous media is formed, and opening and closing of the improved gate are facilitated. By means of the technical scheme, under the condition that an original building structure is not changed, the degree of salt water invasion of the shallow aquifer in the estuary area can be obviously reduced with the low economic cost and the relatively simple construction technology.
本发明公开了一种通过改进闸门结构防治河口地区浅层含水层咸水入侵的方法。根据河口地区的水文地质数据，建立河流浅层含水层咸水入侵数值模型，在考虑工程投入和保证建筑结构安全的条件下，确定最优的闸门向下延长深度，达到显著减轻浅层含水层咸水入侵的效果；在闸底板位置沿闸门槽方向向下开孔，使改进的闸门可以进入闸底板下部含水层，在闸门含水层部分的上下游及两侧布置多孔挡土墙，使之形成不含多孔介质的空腔结构，便于改进的闸门启闭。通过本发明的技术方案，在不改变原有建筑结构的条件下，能以一种较低的经济成本和相对简单的施工工艺，显著减轻河口地区浅层含水层咸水入侵的程度。
