The water in the high water pressure water transmission tunnel, external pressure are high, and the stagnant water structure of structural joint faces very big challenge. In order to ensure that the structural joint can bear high water pressure and ensure the water stopping effect, a double-layer water stopping structure is usually required. Because the lining thickness of the water delivery tunnel is not large, the space between the existing double-layer water stopping structures is very small, and the concrete vibrating space is limited so that the concrete is difficult to pour compactly, and the water stopping structures have the phenomena of water leakage, water seepage, seepage and the like under the action of high water pressure. In addition, the anti-impact performance, the wear resistance and the durability of the existing water stopping structure are poor, and the caulking material is easy to fall off under the long-term scouring action of water flow, so that the water stopping structure is invalid, and the safety of tunnel engineering is endangered. Further, the conventional water stop structure is difficult to perform a water pressure test in terms of quality acceptance and is not replaceable.
On the basis of the water-stopping structure adopted by the water-conveying tunnel, for example, a new waterproof method adopting field spraying polyurethane foam as a caulking seepage-proofing body is proposed by the persons of beam vinlonia et al (new method for processing structural seams of hydraulic buildings [ J ]. water conservancy and hydropower rapid report, 2004, (01):13-17)), and the waterproof comprehensive waterproof property of the foam is combined. The method cancels a water-stopping copper sheet, the adopted foam plastic has no leakage only under 0.2MPa, and the compression strength of the foam plastic material is only 0.2MPa, so that the water-stopping requirement of high internal water pressure cannot be met. For another example, nyquist et al (water stopping and seepage preventing technology [ J ] water conservancy planning and design, 2004, (04):19-24) of eastern improvement engineering water delivery building proposed a GB composite pressing plate type water stopping structure applied to aqueducts.
