Steel-edged rubber waterstop for underground pipe gallery trapezoidal socket and construction method of steel-edged rubber waterstop

The invention relates to the field of underground municipal comprehensive pipe gallery engineering construction, in particular to a steel-edged rubber waterstop for an underground pipe gallery trapezoidal socket and a construction method of the steel-edged rubber waterstop. The two ends of the steel-edged rubber waterstop are connected to form a complete closed loop, the two sides of the steel-edged rubber waterstop are rigidly connected with the butt joint end face of an inserting opening and the face, in butt joint with the butt joint end face, of the trapezoidal socket correspondingly through pouring, and the center of the formed steel-edged rubber waterstop is located at a deformation joint between the inserting opening and the trapezoidal socket. According to the scheme, the positiondeviation of the steel-edged rubber waterstop for the underground pipe gallery trapezoidal socket is small, finished product protection of the steel-edged rubber waterstop for the underground pipe gallery trapezoidal socket i
