Abstract

The invention relates to a seismic wave cross-hole tomography detection boulder stratum underground diaphragm wall and a construction method. The construction method comprises the following steps of boulder detection, blasting pre-decomposition punching of a bead-shaped boulder stratum, pressure and air release covering of a top opening of a blasting hole, and wall brushing and groove cleaning through a square hammer. The method has the advantages that the seismic wave cross-hole tomography equipment is utilized, dense detection paths are formed in the measurement area, then the boulder distribution condition in the measurement area is calculated and deduced, the method has the advantages of being good in reliability, high in intuition and high in accuracy, and efficient and high-quality diaphragm wall construction is guaranteed; the blasting hole drilling construction is performed after the boulder position information in the diaphragm wall range is detected, and then the explosive is loaded according to a discontinuous method, that is, the explosive is only placed at the boulder position, so that the purpose of pre-blasting decomposition is achieved, the grooving progress is greatly improved, the construction difficulty is reduced, and the stability of the groove wall is effectively guaranteed.
