[0024] The embodiments of the present disclosure aim to solve the problem that the existing waterproofing membrane layer and water stop belt may reduce their corrosion resistance when they are placed in concrete; at the same time, settlement and stress deformation may cause deformation of the post-poured belt, thereby forming gaps on both sides and the bottom of the waterproofing jointing material, resulting in a decrease in waterproofing and anti-permeability performance. In view of this, the embodiments of the present disclosure propose a self-waterproofing structure for a post-poured belt of a basement floor, which sets a new waterproofing structure, sets a water stop assembly of a water stop steel plate and a rubber water stop belt, the water stop steel plate (rigid material) provides high-strength support and can effectively resist lateral pressure during concrete pouring, the rubber water stop belt (flexible material) adapts to structural deformation and compensates for displacement caused by concrete shrinkage and cracking; the two form a "rigid-flexible transition layer" and cooperatively resist shear force and uneven settlement; at the same time, the water stop steel plate forms a first physical water-blocking barrier, blocks water penetration channels through metal density, and the water stop belt serves as a second line of defense, compensates for construction joints through elastic sealing, and prevents external water from penetrating along the construction joints; thereby better achieving the waterproofing effect of the post-poured belt.

[0025] As shown in Figures 1 to 3 A self-waterproofing structure for a post-poured belt of a basement floor 3, comprising a basement base layer 1, a water stop assembly 2 is arranged in the basement base layer 1, the water stop assembly 2 realizes preliminary waterproofing of the post-poured belt through the cooperation of a water stop steel plate 21 and a rubber water stop belt 22; a basement floor 3 is arranged on the water stop assembly 2, a post-poured belt groove 4 for pouring the post-poured belt is arranged between the basement floor 3, a cross support bone 5 is installed in the post-poured belt groove 4, and the cross support bone 5 is used for supporting the post-poured belt; a water-absorbing layer 6 that swells in water is arranged on both sides of the post-poured belt; the water-absorbing layer 6 is used for absorbing excess water and swelling to extrude the post-poured belt; the water-absorbing layer 6 is arranged on both sides of the post-poured belt, which can increase the area of the water-absorbing layer 6, and at the same time, it also avoids the problem that the water-absorbing layer 6 is arranged at the bottom of the post-poured belt, which causes the post-poured belt to be deformed when the water-absorbing layer 6 absorbs too much water.

[0026] Through the cooperation of the water stop assembly 2 of the water stop steel plate 21 and the rubber water stop belt 22, the water stop steel plate 21 (rigid material) provides high-strength support and can effectively resist lateral pressure during concrete pouring, the rubber water stop belt 22 (flexible material) adapts to structural deformation and compensates for displacement caused by concrete shrinkage and cracking; the two form a "rigid-flexible transition layer" and cooperatively resist shear force and uneven settlement; at the same time, the water stop steel plate 21 forms a first physical water-blocking barrier, blocks water penetration channels through metal density, and the water stop belt serves as a second line of defense, compensates for construction joints through elastic sealing, and prevents external water from penetrating along the construction joints; thereby better achieving the waterproofing effect of the post-poured belt.

[0027] As shown in Figure 1As shown, the water stop assembly 2 includes a water stop steel plate 21 and a rubber water stop belt 22. Through the combined design of the water stop lever and the rubber water stop belt 22, a multiple protection system is formed by the complementary of rigidity and flexibility: the water stop steel plate 21 blocks the water seepage path and resists the concrete pouring pressure by virtue of high strength and corrosion resistance, while the rubber water stop belt 22 effectively compensates for the cracks caused by structural settlement and temperature expansion through elastic deformation. The two work together to significantly improve the impermeability, adapt to dynamic deformation and corrosion of corrosive media in complex underground environment, and also have the characteristics of large construction tolerance and low maintenance cost.

[0028] As shown in Figure 1 , the water stop steel plate 21 is a galvanized steel plate. The core advantage of using galvanized steel plate as the water stop steel plate 21 lies in the optimized combination of corrosion resistance and structural performance: the surface zinc plating layer can effectively resist the corrosion of Cl⁻ ions in underground water and chemical medium corrosion through the sacrificial anode protection mechanism, prolonging the service life to more than 50 years. At the same time, the steel plate after galvanizing treatment still maintains high strength characteristics, can withstand the lateral pressure and construction load during concrete pouring, and the roughness of the galvanized surface enhances the adhesion with concrete, avoiding interface peeling, suitable for engineering scenarios with high underground water level, strong soil corrosion or long-term waterproofing, significantly reducing maintenance cost and improving the reliability of the basement post-pouring belt waterproof system.

[0029] As shown in Figure 2 , the basement base layer 1 is provided with an isosceles trapezoidal groove 11, and the rubber water stop belt 22 is provided with an isosceles trapezoidal protrusion 221 matched therewith. The isosceles trapezoidal groove 11 is used for clamping the rubber water stop belt 22, that is, the rubber water stop belt 22 is fixed by inserting the isosceles trapezoidal protrusion 221 into the rubber water stop belt 22, and the waterproof work is realized.

[0030] As shown in Figure 1 , the water absorbing layer 6 is made of polyurethane material, and a waterproof layer is arranged on one side of the water absorbing layer 6. The water absorbing layer 6 made of polyurethane material can expand when it absorbs water, and a waterproof layer is arranged on one side of the water absorbing layer 6. It should be noted that this side is the side in contact with the post-pouring belt. By arranging a waterproof layer on one side of the water absorbing layer 6, the water absorbing layer 6 can expand and press the post-pouring belt when heated, while preventing water from entering the post-pouring belt.

[0031] As shown in Figure 1 and Figure 3 , the post-pouring belt is provided with a grouting pipe 7. The grouting pipe 7 arranged in the post-pouring belt is used for precise grouting repair of possible leakage points in the later stage. The above design can timely close the water seepage channel, enhance the self-waterproofing capacity of the structure, reduce the damage to the existing structure during maintenance, reduce the long-term maintenance cost, and prolong the durability of the waterproof system.

[0032] AsFigure 3 As shown, the post-cast strip surface is reserved with a rectangular groove 8, and a polyurethane sealant or water-swelling waterstop is embedded in the rectangular groove 8. The design of the rectangular groove 8 and the embedded polyurethane sealant or water-swelling waterstop on the post-cast strip surface is used to enhance the waterproof reliability of the joint through the dual effects of physical embedding and chemical sealing: the rectangular groove 8 improves the bonding force between the sealing material and the concrete by increasing the contact area, preventing the sealing layer from falling off; the polyurethane sealant adapts to structural deformation due to its high elasticity, and the water-swelling waterstop actively fills the joint gap by swelling in volume when it comes into contact with water, and the two form a dynamic waterproof layer, which can compensate for a joint displacement of ±5mm. At the same time, the geometric constraint effect of the groove can effectively resist water flow scouring and mechanical damage, and has the advantages of convenient construction, aging resistance and self-repairing, which significantly reduces the risk of leakage and reduces the frequency of later maintenance.

Without departing from the spirit and scope of the utility model, the utility model can have various changes and improvements, and these changes and improvements all fall within the scope of the claimed utility model.
