ABSTRACT:
A specific structure of construction to be implemented at the bottom part of a raft foundation to reduce the upward water pressure of the raft foundation bottom or to control the water pressure. An artificial drainage bed structure is constructed at the raft foundation bottom plate, comprising an artificial filter layer, artificial drainage latticed network, water filter/collecting pipe, non-permeable fabric, overflow drain pipe and other elements to reduce and control the impact of a floating force or an excessively large water pressure on the raft foundation bottom plate which is likely to occur during the course of construction.
