Welding requirements of water stop steel plate
The dovetail positioning requirements of the water-stop steel plate are: the upper and lower dovetails face upwards, the horizontal construction joints of the side wall face the back water side, and the vertical construction joints of the side wall face the water side. The steel plates are overlapped by 5cm, and the joint edges are welded. Four joints at the cross part of the steel plate are fully welded, and the steel plate welds are tight.
If unqualified or leaking welds are found, they should be repaired or repaired. The plug mould for vertical construction joints adopts easy-to-close net, which is fixed with small steel bars and welded on structural steel bars.
Specification and model of water stop steel plate:
Water-stop steel plate, also known as water-stop steel plate, can be mainly divided into: common steel plate water-stop, galvanized steel plate water-stop and stainless steel plate water-stop with specifications of 200*2, 200*3, 300*2, 300*3, 350*2, 350*3, 400*4 and 330*5.
Common model of water-stop copper sheet: T2/M (soft state), thickness 1 mm ~ 2.5 mm, width within 600mm, and tensile strength around 200Mpa. Specifications and models of water-stop copper sheet can be provided, including T2-M state, T2-Y2, T3-M and T3-Y2.
Water-stop steel plates are poured separately in the box foundation or basement, and the bottom plate and outer wall plate are concrete. Next time the wallboard concrete is poured, there will be construction joints. When the position of this joint is below the groundwater level, water seepage is easy to occur. This requires technical treatment of this seam, and there are many ways to deal with it.
