pit bottom

With the theoretical analysis and experimental method, the technical elements of water storage pit irrigation method were studied preliminarily including the radius, depth of a, the structural shape of the pit bottom, the space between pits and the number of pits under a tree.

通过理论分析与试验相结合的方法，对蓄水坑灌法的技术要索包括蓄水坑的坑半径、坑深、坑数、坑距及蔷水坑的渗水结构形式等进行了初步研究。

This method can not only ensure the safety of the pit bottom and smooth construction of foundation slab, but also minimize underground water extraction, thus protect underground water resource and reduce the influence on the settlement of the adjacent buildings.

该法可保证基底安全，基础底板施工顺利，并最大限度地减少地下水的抽水量，保护地下水资源，减少对坑边建筑物的沉降影响。
