ActiveCN103266638AReduce labor and material costsImprove the detection rateFoundation testingPre embeddingRadar
The invention relates to a detection method of a leakage site position of an underground concrete continuous wall. The detection method comprises the following steps of: (1) uniformly distributing a plurality of observation wells outside the underground concrete continuous wall; (2) pumping water inside the underground concrete continuous wall, observing the variation conditions of water levels in the observation wells outside the underground concrete continuous wall, and setting the primarily determined leakage direction; (3) after the primary leakage direction is set, determining the primary horizontal position of a leakage site by feeding and checking a tracer outside and inside the continuous wall; and (4) after the primary horizontal position of the leakage site is obtained, carrying out the detection by using a geological radar and an in-well antenna to determine the vertical position and the scale of the leakage site. The detection method has the beneficial effects that 1. the construction process of pre-embedding a pipe inside the concrete continuous wall is eliminated, and the human cost and the material cost are reduced, thereby being simple, convenient and economical; and 2. the joint part of a seam of the concrete continuous wall with a slot base can be detected so that the detection rate of the leakage site can be greatly improved.
