Water stop method of joints of underground continuous wall

摘要

An object of the present invention is to prevent the failure of such flood accident to eliminate the lack of strength with to complete the water-stopping at the joint portion in the construction method to build the underground continuous wall is connected by joints the rear row element and the preceding element is, it is an object thereof is to provide a water stop structure and its method of joint rich practical to enhance the workability. A provided a certain interval in the ground is excavated and built the preceding element of predetermined width, in a subsequent underground continuous wall of excavating and building the trailing element 12 between each preceding element 11, the trailing element 12 the preceding element 11 in the cutout portion 16a formed in the joint section 21 of the, underground continuous wall joint by inserting a water stop plate 20 so as to enter into both of the preceding element 11 and the trailing element 12 in the cutout portion 16a and stop water structure of the part, the method I have the basic means.
