Document Type and Number:
WIPO Patent Application WO/2014/139252
Kind Code:
A1
Abstract:
A method for constructing a large raft foundation in a high-temperature environment. The method comprises: dividing a raft foundation into small blocks; adopting a groove-type construction joint in the middle of the thickness of a construction joint of the raft foundation; overlaying a layer of geotechnical cloth (3) on a plain concrete cushion layer (2); overlaying a layer of PVC waterproof roll material (4) on the geotechnical cloth (3); smearing a mortar levelling layer (5) on the PVC waterproof roll material (4); arranging a rubber water stop belt (10) at the construction joint; laying a horizontal grouting tube (8) and a vertical grouting tube (9) on the rubber water stop belt (10); and after the construction of the groove and waterproof design of the construction joint is finished, pouring small blocks of concrete, maintaining for 7 days, and then constructing on one side or the periphery of the poured small block of raft foundation in a comprehensively forwarding mode. According to the method, the use efficiency of machinery is improved, and the construction period is shortened.
