Because the horizontal pipe made of PE material can not be 100% cemented with the concrete poured on the basement bottom plate, the basement bottom plate is often found to have water seepage at the exposed point of the horizontal pipe in engineering practice due to the pressure action of pressure-bearing underground water, the water seepage at the exposed point of the horizontal pipe is more serious in two seasons, even large-area water accumulation is formed, and the service function of the basement is directly influenced.

In the prior art, a waterproof layer is paved on a basement bottom plate and concrete, and when a horizontal pipe is turned upwards and penetrates through the waterproof layer, the water seepage phenomenon of different degrees still occurs due to temperature change. Meanwhile, some anti-seepage devices between pipelines and walls in the prior art, such as a well chamber anti-seepage device (No. CN212405412U), disclose that the well chamber anti-seepage device includes a well chamber pipeline and two flexible waterproof layers, and the gap between the well chamber pipeline and the wall of the well chamber is blocked by the two flexible waterproof layers, so as to prevent groundwater/seawater from infiltrating into the well chamber, thereby achieving the purpose of waterproofing. But the anti-seepage effect is not good when the buried horizontal pipe is turned upwards and passes through the basement bottom plate.

Therefore, people want to develop a waterproof device which can effectively solve the water seepage phenomenon of the bottom plate of the existing buried horizontal pipe upturning basement.
