摘要： A method for constructing continuous concrete walls free from water leakage under the ground, wherein upon hardening of the concrete of a preceding wall panel the space for the next succeeding wall panel is excavated and while placing a reinforcing steel cage in the space for the next succeeding wall panel, at least one injection pipe is inserted along with the steel cage; placing of concrete in this section Portland cement suspension is jetted at a high pressure from a nozzle of the injection pipe, which is pulled up as it is rotated, whereby clay or slime of bentonite or the like between the end faces of adjacent concrete walls is removed by the fracturing and agitating effect of the jet.
