The invention relates to the civil engineering field and specifically relates to a basement foundation plane leak detection method and system with house subsoil. The method comprises the following steps: on a basement foundation plane, taking a suspected leakage area as a detection area, and after cutting the detection area, observing water seepage flow direction; in the detection area after excavation, arranging a layout interval; summarizing water seepage parameters corresponding to the layout interval; according to the water seepage parameters, obtaining function relationship between waterseepage attenuation and layout interval; and according to the function relationship, calculating position relationship between a water seepage source and the detection area. The method can solve the problems that when water leakage occurs in a basement foundation raft plate, processing is complex and efficiency is low in the prior art; and the method is simple to operate, and does not need large-area excavation, thereby saving labor and cost.
Description
technical field [0001] The invention relates to the field of civil engineering, in particular to a method and system for detecting leakage of a foundation surface of a basement with an atrium. Background technique [0002] Basement foundations generally use raft foundations. [0003] Raft type foundation, that is, full house foundation. It is to connect all independent foundations or strip foundations under the columns with connecting beams, and pour the bottom plate as a whole below. The raft foundation is divided into flat raft foundation and beam-slab raft foundation. The flat raft foundation supports the locally thickened raft type; Generally speaking, when the bearing capacity of the foundation is uneven or the foundation is weak, a raft foundation is used. Moreover, the burial depth of the raft foundation is relatively shallow, and even a non-deep foundation can be used. [0004] The foundation raft in the basement is poured in blocks, and the concrete joints are p...
