[0002] An escalator is a vertical transportation tool, also known as an escalator or an escalator. It is mainly used to connect different floors and provide passengers with convenient up and down transportation. The escalator consists of handrails, walkways, drive systems, and elevator shafts. The elevator shaft is an important part of the elevator system, which is used to accommodate the elevator car and ensure the safety and smoothness of the elevator operation.

[0003] An elevator shaft anti-leakage structure disclosed in Chinese Patent Publication No. (CN218322883U) includes a base and a side wall connecting seat, the side wall connecting seat is arranged at the top of the base, and a shear wall is integrally cast in the middle of the top of the side wall connecting seat, and a waterproof component is arranged at the connection between the side wall connecting seat and the shear wall to prevent groundwater from penetrating, and the waterproof component includes a waterproof anti-ridge cast in the middle of the top of the base and a water-stop steel cylinder embedded in the middle of the waterproof anti-ridge. In this utility model, the base is arranged on the bottom wall of the elevator shaft, and a first waterproof layer is arranged on the inner wall of the outer casting layer to prevent groundwater from penetrating through the base; a waterproof anti-ridge and a water-stop steel cylinder are arranged at the connection between the base and the side wall connecting seat, which can effectively prevent groundwater from penetrating from the fault to the inside of the side wall connecting seat during use, thereby improving the anti-penetration performance of the elevator shaft; the top surface of the waterproof concrete block exceeds the top surface of the outer casting layer, thereby improving the water-isolating effect.

[0004] However, the above patent still has the problem of poor anti-leakage repair effect on the elevator shaft. In the above patent, a waterproof layer is set on the bottom wall of the elevator shaft to prevent penetration of the bottom wall of the elevator shaft. However, this method has poor anti-leakage protection effect on the connection between the top surface and the side wall of the elevator shaft, and it is not convenient to absorb water in the seepage layer structure and solidify the waterproof repair layer, which affects the service life of the anti-penetration structure.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: an anti-leakage repair structure for an escalator shaft, comprising a shaft passage, the inner peripheral wall of the shaft passage being provided with a repair mechanism, and the upper surface of the repair mechanism being provided with a drainage mechanism;

[0007] The repair mechanism comprises a waterproof layer fixed on the inner peripheral wall of the elevator shaft passage, a repair layer is poured on the outer side of the waterproof layer, and a water absorbing layer is fixed on the outer side of the repair layer.

[0008] By adopting this technical solution, waterproof repair is achieved by applying the waterproof layer as a base layer evenly to the water seepage area, ensuring that all potential water seepage points are covered and a solid surface is formed after drying.

[0009] Furthermore, the repair layer is a water glass layer, and the grouting depth of the repair layer is three hundred millimeters.

[0010] By adopting this technical solution, the repair layer can absorb moisture in a liquid state. Once the water glass absorbs moisture, it will begin to harden and form a solid waterproof structure.

[0011] Furthermore, the water absorbing layer is a water absorbing sponge layer.

[0012] By adopting this technical solution, the water-absorbing layer can absorb water in the seepage layer structure and solidify the waterproof repair layer, thereby improving the connection strength and sealing between the repair layer and the original structural layer.

[0013] Furthermore, the waterproof layer is a cement slurry layer.

[0014] By adopting this technical solution, the waterproof layer is used to repair cracks and holes on the concrete surface, provide water resistance, increase waterproofness, and cooperate with the repair structure to cause little damage to the original structure. The repair structure is simple, the materials are green and environmentally friendly, the waterproof effect is good, the service life is long, and it is anti-corrosion and anti-aging.

[0015] Furthermore, the drainage mechanism includes a drainage ditch opened on the upper surface of the repair layer, the inner bottom wall of the drainage ditch is provided with a drainage hole, the inner peripheral wall of the drainage hole is fixed with a drainage pipe, the bottom end of the drainage pipe passes through and extends to the bottom of the waterproof layer and is connected to a sewer pipe.

[0016] By adopting this technical solution, the water-absorbing layer and the repair layer are set at the connection of the inner wall of the elevator shaft passage. When the elevator shaft leaks water, the water-absorbing layer can absorb the moisture at the connection and penetrate downward into the drainage ditch, and then gather along the drainage pipe to be discharged into the sewer pipe, avoiding infiltration.

[0017] Furthermore, the number of the drainage ditches is no less than two and they are evenly distributed on the upper surface of the repair layer.

[0018] By adopting this technical solution, the water can be drained out by utilizing the drainage ditch to reduce the waterproof pressure and improve the waterproof effect.

[0019] Furthermore, the depth of the inner cavity of the drainage ditch is less than the thickness of the repair layer.

[0020] By adopting this technical solution, the water-absorbing layer can absorb the moisture at the connection point and penetrate downward into the drainage ditch for drainage treatment.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] The anti-leakage repair structure of the escalator elevator shaft can ensure that all potential water seepage is covered by the waterproof layer by setting up a repair mechanism and a drainage mechanism, thereby realizing waterproof repair. At the same time, when the elevator shaft leaks, the water-absorbing layer can absorb the moisture at the connection and penetrate downward into the drain ditch, and then gather along the drain pipe to be discharged into the sewer pipe to avoid penetration, and the repair layer can absorb the water in the seepage layer structure and solidify the waterproof repair layer, thereby improving the connection strength and sealing degree between the repair layer and the original structural layer. The repair structure has little damage to the original structure, the repair structure is simple, the material is green and environmentally friendly, the waterproof effect is good, the service life is long, and the corrosion and aging resistance are anti-corrosive.

[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] See also Figure 1 The anti-leakage repair structure of the escalator shaft in this embodiment includes a shaft passage 1, the inner wall of the shaft passage 1 is provided with a repair mechanism 2, and the upper surface of the repair mechanism 2 is provided with a drainage mechanism 3.

[0029] See also Figure 2In order to improve the waterproof repair effect, the repair mechanism 2 in this embodiment includes a waterproof layer 201 fixed to the inner wall of the elevator shaft passage 1, and a repair layer 202 is poured on the outside of the waterproof layer 201. The water absorption layer 203 and the repair layer 202 are arranged at the connection between the inner wall of the elevator shaft passage 1, and the water absorption layer 203 is fixed on the outside of the repair layer 202.

[0030] In this embodiment, the repair layer 202 is a water glass layer. The repair layer 202 can absorb moisture in a liquid state. Once the water glass absorbs moisture, it will begin to harden and form a solid waterproof structure. The grouting depth of the repair layer 202 is three hundred millimeters, which absorbs water in the seepage structure and solidifies the waterproof repair layer to improve the connection strength and sealing between the repair layer 202 and the original structural layer. The water-absorbing layer 203 is a water-absorbing sponge layer, and the waterproof layer 201 is a cement slurry layer. The waterproof layer 201 is used as the base layer and is evenly applied to the seepage area to ensure that all potential seepage points are covered. A solid surface is formed after drying, thereby achieving waterproof repair.

[0031] See also Figure 3 In order to facilitate the use of waterproof drainage efficiency, the drainage mechanism 3 in this embodiment includes a drainage ditch 301 opened on the upper surface of the repair layer 202, and the inner bottom wall of the drainage ditch 301 is provided with a drainage hole 302. The inner peripheral wall of the drainage hole 302 is fixed with a drainage pipe 303. The bottom end of the drainage pipe 303 penetrates and extends to the bottom of the waterproof layer 201 and is connected to a sewer pipe 304. When the elevator shaft leaks water, the water-absorbing layer 203 can absorb the moisture at the connection and penetrate downward and drip into the drainage ditch 301, and then gather along the drainage pipe 303 to the sewer pipe 304 for discharge to avoid penetration.

[0032] In this embodiment, the number of the drainage grooves 301 is not less than two and they are evenly distributed on the upper surface of the repair layer 202 . The depth of the inner cavity of the drainage groove 301 is less than the thickness of the repair layer 202 .

[0033] The working principle of the above embodiment is:

[0034] The waterproof layer 201 is used as the base layer and is evenly applied to the water seepage area to ensure that all potential water seepage points are covered. A solid surface is formed after drying, thereby achieving waterproof repair. At the same time, the water-absorbing layer 203 and the repair layer 202 are arranged at the connection of the inner wall of the elevator shaft passage 1. When the elevator shaft seeps water, the water-absorbing layer 203 can absorb the moisture at the connection and penetrate downward into the drain ditch 301, and then converge along the drain pipe 303 to the sewer pipe 304 for discharge to avoid penetration. The repair layer 202 can absorb moisture in a liquid state. Once the water glass absorbs moisture, it will begin to harden and form a solid waterproof structure, which can absorb water in the seepage structure and solidify the waterproof repair layer, thereby improving the connection strength and sealing between the repair layer 202 and the original structural layer.
