The drainage channels with smaller cross sections are surrounded by the drainage parts 12 and the lower plates 822 between the expansion waterproof strips 81, and when the expansion waterproof strips 81 expand, the space of the drainage channels is increased to generate suction force due to the fact that the lower plates 822 rise together with the supporting parts. The part of the long waterproof strip 7 corresponding to the front opening position is driven by the plugging column 85 to rise along with the guide anti-seepage frame 82, so that a drainage seam communicated with the front opening is opened at the position, the leaked water originally gathered at the leakage position is quickly sucked under the action of suction, and most of leaked water can enter the anti-seepage assembly 8 due to the water suction effect even if the leakage quantity is small, so that the expansion effect of the expansion waterproof strip 81 is increased, the pressure sensor 84 is triggered to send out a signal, and the sensitivity of detecting the leakage condition is increased. On the other hand, the water body can be prevented from diffusing to the two sides along the long waterproof strip 7 to enlarge the influence range, and when the external water body leaks to the position of the long waterproof strip 7, the water body can be quickly absorbed and transferred to the leakage water storage tank 4, so that the external water body is prevented from entering the building to cause pollution.

The drainage part 12 is provided with a plurality of convex water diversion blocks 15, a drainage groove 14 is formed between every two adjacent water diversion blocks 15, the bottom of each seepage prevention assembly 8 is closely attached to the bottom of each drainage groove 14, each drainage groove 14 at least corresponds to one seepage prevention assembly 8, the front part of each drainage groove 14 is provided with a seepage prevention groove 32, and the rear discharge port is communicated with the seepage water storage tank 4 through the middle rear part of each drainage groove 14.

So that the seepage water discharged through the seepage-proofing member does not contact the steel bars, reduces corrosion to the steel bars, and is discharged to the seepage water storage tank 4 through the drainage tank 14 quickly.

The front opening width of the drainage tank 14 is larger than the opening width of the rear part of the drainage tank 14, the middle part of the drainage tank 14 is a trapezoid section with a width which is convergent backward, the outermost part of the drainage part 12 is also provided with a water tank setting area 13 with a height lower than the bottom of the drainage tank 14, the water tank setting area 13 is used for setting a leakage water storage tank 4, a water inlet of the leakage water storage tank 4 is detachably connected with the rear opening of the drainage tank 14 through a sealing structure, the rear side of the outer impermeable member 3 is provided with a plurality of baffles 33, the baffles 33 are distributed along the length direction of the outer impermeable member 3, the baffles 33 are positioned between two adjacent leakage water storage tanks 4 after the outer impermeable member 3 is installed, namely, the baffles are used for separating and protecting the leakage water storage tanks 4, and the water tank setting area 13 is provided with connecting reinforcing bars III which correspondingly extend upward to the baffles 33.

For example, when the building is a sewage collection tank, the water in the leakage water storage tank 4 indicates that the internal water leaks outwards if the color and turbidity degree are close to the collected sewage, otherwise, the external water is more likely to start to leak inwards; if the building is a water storage tank for supplying clean water, the water color and turbidity are high, which means that the external water leaks inwards, and the water is clean, which means that the internal water source leaks outwards again.

The waterproof sealing structure is characterized in that a first sealing rubber strip 5 is arranged between the protruding anti-seepage portion 11 and the side plate member 2, a second sealing rubber strip 6 is arranged between the side plate member 2 and the outer anti-seepage member 3, a trapezoid step structure 21 is arranged on one side of the side plate member 2 towards the outer anti-seepage member 3, a trapezoid groove structure 31 corresponding to the trapezoid step structure 21 is arranged on the front side of the outer anti-seepage member 3, the upper end of the front side of the outer anti-seepage member 3 is pressed on the vertical surface of the side plate member 2, the second sealing rubber strip 6 is positioned on the upper step surface of the trapezoid step structure 21, the vertical surface of the trapezoid step structure 21 is an inclined surface structure with the bottom extending obliquely towards the anti-seepage groove 32, and the long waterproof strip 7 is clamped on the front side and the rear side of the lower part of the trapezoid groove structure 31. This structure makes it easy for the water leaking from the inside or outside to collect at the position where the long weather strip 7 is provided.

The convex impermeable part 11 is provided with a grouting groove 9 above the first sealing rubber strip 5, the outer impermeable member 3 is also provided with a grouting groove 9 above the second sealing rubber strip 6, and the tight connection of the upper joint is ensured to have better waterproof property through on-site grouting.
