s2, binding walls and column dowels, paying out position lines of the walls and column dowels on the foundation bottom plate cushion layer, binding foundation bottom plate steel bars, connecting the steel bars according to design and specification requirements, binding firmly and arranging a bottom plate steel bar protective layer cushion block; then binding the embedded wall and column inserting bars in the foundation bottom plate, firmly positioning the inserting bars of the wall and the column extending into the foundation according to the position lines of the wall and the column popped out from the cushion layer, wherein the depth of the inserting bars entering the foundation is in accordance with the requirement of designed anchoring length, the length of the inserting bars extending out of the top surface of the bottom plate is more than or equal to 45d, joints are staggered by 50 percent, and two positioning stirrups are bound at the lower part to ensure that the inserting bars are vertical;
s3, mounting a water-stopping steel plate, installing the water-stopping steel plate on site after the assembly welding of a water-stopping steel plate corner component is completed, arranging the water-stopping steel plate in the middle of the wall thickness of the corner part of the outer wall of the basement, burying the water-stopping steel plate to a depth which is half of the width of the water-stopping steel plate, enabling a concave surface formed by the folded edge to face the upstream surface, and supporting and fixing the water-stopping steel plate by using short steel bars; the connection of the water-stopping steel plates of other straight-line sections adopts double-sided lap welding, the lap length is 50mm, the welding survives in two times, welding skins are knocked off after the first welding, the quality of welding seams is checked, repair welding is carried out if necessary, the welding is carried out on the back sides of the water-stopping steel plates in the second time according to the same sequence, the welding seams are required to be full and continuous, tight and free of seepage points, and the water-stopping steel plates are kept horizontal, vertical and consistent in elevation;
and S4, after the installed foundation steel bars, wall column joint bars and water stop steel plates are qualified through quality inspection, entering the next procedure.
