[0002] At present, most of the steel plate waterstops used in construction projects only have a single-sided water-stopping function. However, with the needs of urban development, a large number of underground projects have emerged. As an important structure, underground water tanks are widely used in water plants, sewage treatment plants, sponge cities and other construction fields. Once the construction joints of underground water tanks leak, it will cause mutual contamination of internal and external water resources, and because they are buried deep underground, it is extremely difficult to repair.

[0003] The traditional steel plate waterstop has a single waterstop path and poor double-sided waterstop effect; and the double-sided steel plate waterstop with "double wings" is not conducive to production and welding installation due to its complex structure. Therefore, it is necessary to optimize the structure of the steel plate waterstop so that both sides of the pool wall have anti-seepage and water-stopping functions. Utility Model Content

DETAILED DESCRIPTION

[0030] The present invention will be further described in detail below in conjunction with specific implementation methods.

[0031] Embodiment 1

[0032] The double-sided steel plate waterstop for underground water pools with a supporting and positioning device is arranged at the construction joint in the wall between the A side and the B side, and includes a double-sided steel plate waterstop body and a supporting and positioning device; the double-sided steel plate waterstop body includes a supporting welding area, a raised section on the A side that is bent and protrudes toward the A side, a raised section on the B side that is bent and protrudes toward the B side, and another supporting welding area that are arranged in sequence; a groove is arranged in the middle of the supporting and positioning device, and the two sections of the supporting welding areas of the double-sided steel plate waterstop body are inserted into the grooves of the two supporting and positioning devices, and the supporting welding areas and the grooves are fixed by welding. In this embodiment, the A side is Figure 1 The left side of the Figure 1 on the right side.

[0033] Figure 1 As shown, the middle part of the wall is perpendicular to the construction joint and is defined as the alignment surface. The two support welding areas are located at the alignment surface. The raised section on the A side is located on the side of the alignment surface facing the A side, and the raised section on the B side is located on the side of the alignment surface facing the B side. The raised section on the A side includes a lower water stop wing on the B side, an adjustment section on the A side, and a lower water stop wing on the A side, which are bent into a trapezoid in sequence. The raised section on the B side includes an upper water stop wing on the A side, an adjustment section on the B side, and an upper water stop wing on the B side, which are bent into a trapezoid in sequence. The upper water stop wing on the B side and the lower water stop wing on the A side are connected and coplanar, and the connection is the construction joint.

[0034] Figure 4 As shown, the angle between the upper waterstop wing on the A side and the adjustment section on the B side is 135 degrees, and the angle between the adjustment section on the B side and the upper waterstop wing on the B side is 135 degrees; the angle between the lower waterstop wing on the B side and the adjustment section on the A side is 135 degrees, and the angle between the adjustment section on the A side and the lower waterstop wing on the A side is 135 degrees.

[0035] Figure 4 As shown, parallel to the construction joint direction, the width of the double-sided steel plate waterstop body is 60mm; parallel to the alignment surface direction, the height of the support welding area is 20mm, the height of the lower waterstop wing on the B side, the lower waterstop wing on the A side, the upper waterstop wing on the A side, and the upper waterstop wing on the B side are all 30mm, the height of the double-sided steel plate waterstop body is H, and the height of the adjustment section on the A side and the adjustment section on the B side are both h, H = 160 + 2h.
