Abstract
Description
Technical Field
[0001] This utility model relates to the field of waterproofing engineering technology, and in particular to a waterproofing layer protection device. Background Technology
[0002] In construction, water conservancy and other engineering projects, the waterproof protective layer plays a key role in protecting the waterproof system and extending the service life of the building. It is mainly used to prevent the waterproof layer from being damaged by external factors such as ultraviolet radiation and mechanical damage.
[0003] Traditional waterproof protective layer devices have poor protective performance and are difficult to withstand external impacts and punctures, making the waterproof layer easily damaged. In addition, the drainage function of the protective device is not perfect, and water can easily accumulate between the protective device and the waterproof layer, increasing the risk of leakage. Furthermore, they are inconvenient to install and maintain, resulting in high maintenance costs. Utility Model Content
[0004] The technical problem to be solved by this utility model is that the existing waterproof protective layer protection devices have the disadvantages of poor protective performance, poor drainage, and inconvenient installation and maintenance. Therefore, we propose a waterproof protective layer device.
[0005] To achieve the above objectives, this application adopts the following technical solution: a waterproof layer protection device, comprising a base layer, a waterproof layer, a buffer layer, a protective layer, and a drainage structure, wherein the waterproof layer is laid on the surface of the base layer, the buffer layer covers the waterproof layer, the protective layer is disposed above the buffer layer, and the drainage structure is disposed at the edge of the protective layer and communicates with the buffer layer.
[0006] Preferably, the buffer layer is a polyethylene foam board layer with a thickness of 3-5 cm.
[0007] Preferably, the protective layer comprises multiple spliced precast concrete slabs, and elastic sealing strips are provided between adjacent spliced precast concrete slabs.
[0008] Preferably, the upper surface of the multiple precast concrete slabs is provided with anti-slip texture, which is in the form of an interlaced grid.
[0009] Preferably, the drainage structure includes a drainage channel and a drainage pipe. The drainage channel is disposed at the edge of the protective layer and communicates with the bottom of the buffer layer. The drainage pipe communicates with the bottom of the drainage channel and extends to the drainage system.
[0010] Preferably, the drainage trough is equipped with a filter screen, which is located above the drainage pipe.
[0011] The technical effects and advantages of this utility model are as follows:
[0012] In this invention, the dual protection of the buffer layer and the protective layer effectively resists external impacts, punctures, and abrasions, reducing the risk of damage to the waterproof layer and extending the service life of the waterproof system. The drainage structure design can promptly drain water accumulated in the buffer layer, preventing water from damaging the waterproof layer and reducing the possibility of leakage. The protective layer is made of multiple precast concrete slabs spliced together, which is convenient to install. When a precast concrete slab is damaged, it can be replaced individually, resulting in low maintenance costs. The anti-slip texture on the upper surface of the protective layer can improve safety during use and prevent accidental injury to personnel. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0019] Reference Figures 1-4 As shown, this utility model provides a technical solution: a waterproof layer protection device, including a base layer 1, a waterproof layer 2, a buffer layer 3, a protective layer 4, and a drainage structure 5. The waterproof layer 2 is laid on the surface of the base layer 1, the buffer layer 3 covers the waterproof layer 2, the protective layer 4 is disposed above the buffer layer 3, and the drainage structure 5 is disposed at the edge of the protective layer 4 and communicates with the buffer layer 3. By setting up the base layer 1, waterproof layer 2, buffer layer 3, protective layer 4, and drainage structure 5, the waterproof layer 2, laid on the surface of the base layer 1, serves a waterproof function; the buffer layer 3, covering the waterproof layer 2, can buffer external impact forces and prevent the waterproof layer 2 from being directly damaged; the protective layer 4, disposed above the buffer layer 3, further enhances the protection of the waterproof layer 2; and the drainage structure 5, disposed at the edge of the protective layer 4 and communicating with the buffer layer 3, can promptly drain the accumulated water in the buffer layer 3, reducing the risk of leakage.
[0020] Reference Figure 2As shown in this embodiment: the buffer layer 3 is a polyethylene foam board layer with a thickness of 3-5cm. The polyethylene foam board has good buffering performance and a certain degree of flexibility, which can ensure the buffering effect without affecting the stability of the overall structure.
[0021] Reference Figure 3 As shown in this embodiment: the protective layer 4 includes multiple spliced precast concrete slabs, with elastic sealing strips 6 between adjacent spliced precast concrete slabs. The upper surface of the spliced precast concrete slabs is provided with anti-slip textures, which are arranged in an interlaced grid pattern. By utilizing the high strength of the precast concrete slabs, they can effectively resist external impacts and wear. The splicing method facilitates installation and subsequent replacement. The elastic sealing strips 6 can prevent moisture from seeping in from the slab joints, enhancing waterproof performance. By setting anti-slip textures in an interlaced grid pattern, the friction of the protective layer 4 surface can be increased, preventing people from slipping, and at the same time, it can also distribute pressure to a certain extent.
[0022] Reference Figure 2 and Figure 4 As shown in this embodiment: the drainage structure 5 includes a drainage trough 7 and a drainage pipe 8. The drainage trough 7 is located at the edge of the protective layer 4 and is connected to the bottom of the buffer layer 3. The drainage pipe 8 is connected to the bottom of the drainage trough 7 and extends to the drainage system. A filter screen 9 is provided inside the drainage trough 7. The filter screen 9 is located above the drainage pipe 8. Through the structure of the drainage trough 7 and the drainage pipe 8, accumulated water can flow into the drainage trough 7 through the buffer layer 3 and then be discharged through the drainage pipe 8, achieving rapid drainage. At the same time, by setting the filter screen 9 inside the drainage trough 7, debris can be intercepted to prevent the drainage pipe 8 from becoming blocked.
[0023] Working Principle: The system consists of a base layer 1, a waterproof layer 2, a buffer layer 3, a protective layer 4, and a drainage structure 5. The waterproof layer 2 is laid on the surface of the base layer 1 to provide waterproofing. The buffer layer 3 covers the waterproof layer 2, cushioning external impacts and preventing direct damage. The protective layer 4 is placed above the buffer layer 3 to further enhance the protection of the waterproof layer 2. The drainage structure 5 is located at the edge of the protective layer 4 and connects to the buffer layer 3, allowing for timely drainage of water accumulated in the buffer layer 3 and reducing the risk of leakage. Polyethylene foam boards provide good cushioning performance and a certain degree of flexibility, ensuring cushioning without compromising the overall structural stability. The high strength of precast concrete slabs effectively resists external impacts and wear. The splicing method facilitates installation and future replacement. Elastic sealing strips 6 prevent moisture from seeping into the slab joints, enhancing waterproofing. Anti-slip textured patterns in an interlaced grid increase the friction on the surface of the protective layer 4, preventing slips and dispersing pressure to some extent. Drainage channels 7 and drainage pipes further enhance the waterproofing. The structure of the 8 allows accumulated water to flow through the buffer layer 3 into the drainage channel 7, and then out through the drainage pipe 8, achieving rapid drainage. Simultaneously, a filter screen 9 installed inside the drainage channel 7 intercepts debris, preventing blockage of the drainage pipe 8. In use, first, clean the surface of the base layer 1, ensuring it is flat, dry, and clean. Then, lay the waterproof layer 2 on the surface of the base layer 1, using waterproof membrane or waterproof coating, following conventional construction techniques. Next, lay polyethylene foam board as the buffer layer 3 on the waterproof layer 2, cutting the polyethylene foam board to appropriate sizes and splicing them tightly to cover the entire surface of the waterproof layer 2. Then, splice the precast concrete slabs according to the design pattern, filling the gaps between adjacent precast concrete slabs with elastic sealing strips 6 to ensure a good seal. Install the drainage channel 7 at the edge of the protective layer 4, connecting the drainage channel 7 to the bottom of the buffer layer 3. Then, connect the drainage pipe 8 to the bottom of the drainage channel 7 and extend the drainage pipe 8 to the drainage system. Install the filter screen 9 inside the drainage channel 7. Through these steps, the installation of the protective layer device is complete.
