In some specific cases, rubber waterstops are used to seal the construction joints by splicing. The existing splicing method is to connect and fix the two sides of the waterstop with steel plates, and water leakage is prone to occur at the splicing. Utility Model Content

[0013] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.
[0014] Reference Figure 1-3 As shown, a new-old concrete construction joint waterproof structure comprises a new concrete wall 1, an old concrete wall 2, and a rubber waterproof belt embedded in the new concrete wall 1 and the old concrete wall 2. Steel plates 4 are provided on both sides of the rubber waterproof belt, and a sealing connection component for splicing the rubber waterproof belt is provided. The sealing connection component comprises a sealing sleeve 5, a pressing plate 6 and a connecting sleeve 7 arranged in pairs. Slots 8 for the rubber waterproof belt to extend into are provided at both ends of the sealing sleeve 5. A retaining wall 9 for separation is provided between the slots 8 at both ends. The shape of the inner wall contour of the slot 8 matches the outer contour of the rubber waterproof belt. In this way, the rubber waterproof belt can provide a reliable seal after installation, and is also convenient for later installation. During the subsequent construction, local damage was found, so the rubber waterproof belt was cut and spliced. The paired pressure plates 6 were respectively abutted against the outer contour surface of the sealing sleeve 5, and were clamped and fixed on the steel plate 4 through the connecting sleeve 7. The sealing sleeve 5 was made of rubber. By installing the rubber waterproof belts on both sides in the slot 8, the rubber shrinks by itself and is compressed by the pressure plate 6 to provide a reliable seal. In this embodiment, the inner wall surface of the slot 8 is provided with a raised sealing strip 10 along its contour, and the sealing strip 10 is inclined toward the inner side of the slot 8. The raised sealing strip 10 further improves the seal between the sealing sleeve 5 and the rubber sealing belt, and the inclined sealing strip 10 is convenient for insertion during installation.
[0015] The connecting sleeve 7 is provided with three abutting surfaces, which respectively abut against the side surface of the sealing sleeve 5 and the outer sides of the two pressing plates 6 adjacent to the side surface of the sealing sleeve 5. The connecting sleeve 7 is fixedly connected to the steel plate 4 by fasteners. In this embodiment, in order to avoid damage to the sealing sleeve 5, the two ends of the connecting sleeve 7 extend to both sides to reserve a length for rivet installation. Through the three abutting surfaces, it is fully cooperated with the pressing plate 6 and the sealing sleeve 5 for clamping, and can also provide a reliable connection. An angle steel 11 is provided at the construction joint between the new concrete wall 1 and the old concrete wall 2. The concave side of the angle steel 11 faces the water-facing surface. A water stop strip 12 is provided on the side of the angle steel 11 facing the construction joint. The water stop strip 12 is fixedly connected to the closed side of the angle steel 11. The side of the angle steel 11 facing the water-facing surface is filled with caulking paste and cement mortar. The caulking paste is applied to the surface where the angle steel 11 abuts against the new and old concrete walls 2, and the cement mortar is used to fill and level the wall surface.
[0016] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
