Document Type and Number:
WIPO Patent Application WO/2021/013201
Kind Code:
A1
Abstract:
The present invention relates to the technical field of foundation pit support and protection, and relates to a water stopping device and method for a ground continuous wall joint in a high-water-rich coastal area. A continuous wall horizontal rib and a continuous wall vertical main rib are mechanically connected, and a perforated steel pipe is tied and overlapped on a first diaphragm reinforcement cage; a galvanized iron coating is mounted at an outer side of a H-shaped steel plate, the galvanized iron coating and a pressing steel bar are welded by means of spot welding, the H-shaped steel plate is welded and connected to the first diaphragm reinforcement cage, a U-shaped stirrup is welded and connected to a single side of the continuous wall horizontal rib, a grouting pipe and a second diaphragm reinforcement cage are tied and overlapped, and the second diaphragm reinforcement cage is suspended and embedded between H-shaped steel plate flaps; sand bags are stacked on an outer side of a H-shaped steel plate joint web, and a filling height is the height of the underground diaphragm wall. The invention has an ideal water-proof effect, and can effectively prevent the concrete from flowing around, and the arrangement of the perforated steel pipe ensures the water-stopping effect at seam joints.
