DETAILED DESCRIPTION

[0021] The embodiments of the technical solutions of the present application will be described in detail below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present application, and therefore only serve as examples, and cannot limit the protection scope of the present application.

[0022] Please refer to Figure 1 The present application provides a waterproof cover plate for a subway underground station vertical shaft maintenance rescue hole, comprising,

[0023] The top cover plate 1 comprises a bottom plate 11 and an annular protrusion 12 arranged on the edge of the bottom plate 11. The internal shape of the annular protrusion 12 is consistent with and corresponds to the external shape of the cover plate inner side water retaining ridge 2. The internal size of the annular protrusion 12 is larger than the external size of the cover plate inner side water retaining ridge 2, so that there is a gap between the annular protrusion 12 and the cover plate inner side water retaining ridge 2. The top cover plate 1 is a reinforced concrete structure and is higher than the vertical shaft top plate. The top surface is horizontal, the bottom surface is provided with protrusions around, and the remaining part is horizontal.

[0024] The cover plate inner side water retaining ridge 2 is arranged around the hole of the rescue maintenance hole. The cover plate inner side water retaining ridge 2 is arranged inside the annular protrusion 12 of the top cover plate 1. The top surface of the cover plate inner side water retaining ridge 2 is attached to the inner side surface of the bottom plate 11 of the top cover plate 1. The cover plate inner side water retaining ridge 2 is arranged around the rescue maintenance hole and corresponds to the protrusions around the bottom surface of the top cover plate 1. The top part of the water retaining ridge is tightly attached to the bottom surface of the top cover plate 1. It plays a role of isolating surface water in structure.

[0025] Side slope stopper 3: the side slope stopper 3 is arranged on the top plate of the shaft, and is wrapped outside the top cover plate 1; the side slope stopper 3 is arranged on the top plate of the shaft and is wrapped outside the top cover plate 1 in structure. The stopper has two functions: one is to slope between the top plate and the top cover plate 1, so that it is smooth and prevents people from falling; the other is closely attached to the side wall of the top cover plate 1, which plays a role of isolating surface water in structure.

[0026] Water stop 4: one end of the water stop 4 is embedded into the side slope stopper 3, and the other end abuts against the outer side wall of the top cover plate 1; the water stop 4 is water-swelling rubber, and the water stop 4 is sequentially provided with multiple layers along the axis direction of the side slope stopper 3 from top to bottom. The material of the water stop 4 is water-swelling rubber, which is a unique new rubber product. It has the performance of general rubber products and the performance of swelling by itself when encountering water, and is a new type of waterproof material, which is more reliable than general rubber in waterproof effect. The water-swelling rubber has characteristics and advantages over ordinary rubber. The rubber swells by 2-3 times after encountering water, fills all irregular surfaces, cavities and gaps of the joint, and generates a huge contact pressure, thereby completely preventing leakage. When the joint or construction joint is displaced and the gap exceeds the elastic range of the material, the ordinary rubber water stop material loses the water stopping effect. However, the material can still stop water by swelling through water absorption. Using water-swelling rubber as a leakage sealing and water stopping material not only saves the amount of use, but also eliminates the characteristics of elastic fatigue caused by excessive compression of general elastic materials, so that the waterproof effect is more reliable. The water stop 4 is embedded into the inner wall of the side slope stopper 3 by pre-embedding, and a total of three layers are provided. After the top cover plate 1 covers, the gap between the cover plate and the side slope stopper 3 is tightly sealed, thereby playing a waterproof role.

[0027] Water stop pad 5: the bottom surface of the water stop pad 5 is embedded into the top plate of the shaft, and the top surface of the water stop pad 5 is attached to the bottom of the annular protrusion 12. The material of the water stop pad 5 is water-swelling rubber putty. The water-swelling rubber putty has good adhesion and low-temperature performance of durable consumer goods, and has good swelling characteristics. The product is synthesized from a variety of high molecular chemical materials, and has higher strength than general putty. The pad is embedded into the lower edge of the top plate of the shaft by pre-embedding, and the top surface is tightly attached to the protrusion at the bottom of the top cover plate 1, thereby playing a waterproof role. The water stop 4 and the water stop pad 5 are annularly arranged along the inner wall of the side slope stopper 3.

[0028] As further improvement of the above technical scheme, the lock 6, the cover plate pad and the block pad are further included, the cover plate pad is embedded into the top cover plate 1 through the cover plate anchor 63, one end of the cover plate anchor 63 is fixed on the cover plate pad and the other end is embedded into the cover plate, the block pad is embedded into the lateral slope block 3 through the block anchor 64, one end of the block anchor 64 is fixed on the block pad and the other end is embedded into the top cover plate 1, one end of the lock 6 is locked on the cover plate pad and the other end is locked on the block pad 62. The lock 6 is made of stainless steel, the cover plate anchor 63 and the block anchor 64 are made of Q235 steel. The lock 6 is arranged to connect the cover plate and the lateral slope block 3, which plays the role of anti-theft and anti-invasion. The lock 6 is connected with the cover plate and the block through the block pad 62 and the cover plate pad 61.

[0029] The water retaining ridge is hidden in the inside of the cover plate, which is better in sealing and does not adversely affect the flatness of the top surface. Meanwhile, the leveling block is arranged to play the role of leveling and water retaining. The water stopping material is arranged in the gap to ensure that the hole does not seep water.

[0030] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should be covered in the scope of the claims and the specification of the present application.
