Abstract
Description
Technical Field
[0001] This utility model relates to the field of drainage board technology, and more specifically, to a composite drainage board with a three-dimensional drainage channel. Background Technology
[0002] In many fields such as urban construction, transportation engineering, water conservancy projects, and underground space development, the reliability and efficiency of drainage systems are crucial. With the continuous expansion of project scale, the increasing demands for use, and the complexity and variability of environmental conditions, traditional drainage structures have gradually revealed many shortcomings in dealing with various drainage tasks.
[0003] Traditional drainage structures typically employ planar or simple two-dimensional drainage channel designs. For example, the inner diameter of drainage channels or pipes on ordinary drainage boards is relatively fixed, resulting in a limited effective cross-sectional area. When faced with large amounts of accumulated water, the water flow capacity is restricted, making it difficult to quickly introduce and drain the water, easily leading to water accumulation and affecting the normal operation of engineering facilities. Furthermore, water often contains impurities such as silt and debris. The relatively smooth interior of traditional drainage structures results in minimal turbulence during water flow, making it easy for impurities to deposit within the drainage channels. To address these problems, this device was invented. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a composite waterproof and drainage board with a three-dimensional drainage channel to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a composite waterproof and drainage board with a three-dimensional drainage channel, comprising, from top to bottom, a surface protective layer, a three-dimensional drainage layer, an intermediate support layer, and a bottom anti-seepage layer. The layers are tightly connected into a whole by hot-melt bonding. The surface protective layer is used to protect the three-dimensional drainage layer from external damage. The three-dimensional drainage layer is composed of multiple three-dimensional drainage units. Each three-dimensional drainage unit has a hollow structure and forms a three-dimensional drainage channel inside. The side wall of the three-dimensional drainage unit has multiple water guiding holes that communicate with adjacent three-dimensional drainage units. The intermediate support layer has a grid structure, and the bottom anti-seepage layer has a multi-layer composite structure.
[0006] Furthermore, the surface protective layer is made of high-density polyethylene film, with several raised anti-slip particles evenly distributed on its surface. The height of the anti-slip particles is 1mm-3mm, and the spacing between adjacent anti-slip particles is 5mm-10mm.
[0007] Furthermore, insertion holes are provided on the sides of the three-dimensional drainage units that come into contact with each other, and reinforcing ribs are provided between adjacent three-dimensional drainage units. The two ends of the reinforcing ribs are inserted into the insertion holes of the adjacent three-dimensional drainage units to achieve connection and fixation.
[0008] Furthermore, multiple raised structures are provided on the upper and lower inner walls of the three-dimensional drainage channel. The raised structures are circular, triangular or square, with a height of 1mm-5mm and a spacing of 2mm-10mm between adjacent raised structures.
[0009] Furthermore, the bottom seepage-proof layer consists of a waterproof membrane layer, a reinforcing fiber layer, and a base layer from top to bottom. The waterproof membrane layer is made of polyvinyl chloride polymer waterproof material with a thickness of 0.5mm-1.5mm. The reinforcing fiber layer is woven from basalt fiber material with a thickness of 1mm-3mm. The base layer is made of fiberglass material with a thickness of 5mm-15mm.
[0010] Furthermore, the lower surface of the base layer is provided with multiple support feet, the height of which is 10mm-20mm.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. The three-dimensional drainage layer is composed of multiple hollow three-dimensional drainage units, forming a three-dimensional drainage channel inside. Water guide holes are opened on the side walls to connect the drainage channels to form a three-dimensional drainage network, which greatly increases the effective cross-sectional area of the drainage channel, improves drainage efficiency, and can quickly introduce and discharge accumulated water. At the same time, the inner wall of the three-dimensional drainage channel is equipped with a raised structure to increase the turbulence effect of water flow, promote the discharge of impurities, prevent blockage, and further ensure smooth drainage.
[0013] 2. Reinforcing ribs are installed between adjacent three-dimensional drainage units, and they are connected and fixed through plug holes to enhance the stability and firmness of the overall structure of the three-dimensional drainage layer, ensuring that it can maintain good drainage performance even in complex environments.

[0022] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0024] See attached document Figures 1-4 The composite waterproof and drainage board of the three-dimensional drainage channel in this embodiment includes, from top to bottom, a surface protective layer 1, a three-dimensional drainage layer 2, an intermediate support layer 3 and a bottom seepage-proof layer 4. The surface protective layer 1 is used to protect the three-dimensional drainage layer 2 from external damage. The layers are tightly connected into a whole by hot-melt bonding to achieve efficient drainage and reliable seepage prevention.
[0025] See attached document Figure 2 The surface protective layer 1 is made of high-density polyethylene film with a thickness of 0.2-0.5mm. Several raised anti-slip particles 11 are evenly distributed on the upper surface of the surface protective layer 1. The height of the anti-slip particles 11 is 1mm-3mm and the spacing is 5mm-10mm. Its lower surface is tightly attached to the three-dimensional drainage layer 2. The anti-slip particles 11 can increase the friction between the drainage board and the upper covering material, prevent the drainage board from sliding and displacing during use, and ensure its positional stability.
[0026] See attached document Figure 2 and Figure 5The three-dimensional drainage layer 2 is composed of multiple three-dimensional drainage units 21. Each three-dimensional drainage unit 21 is a hollow structure with a circular, square, or elliptical cross-section. It forms a three-dimensional drainage channel 22 inside. The side wall of the three-dimensional drainage unit 21 is provided with multiple water guide holes 23 that are connected to adjacent three-dimensional drainage units 21. The spacing between adjacent water guide holes 23 is 15-30mm, so that each three-dimensional drainage channel 22 is interconnected to form a three-dimensional drainage network. This three-dimensional drainage structure greatly increases the effective cross-sectional area of the drainage channel, improves drainage efficiency, and can quickly introduce accumulated water into the drainage channel and discharge it.
[0027] On the two sides of two adjacent three-dimensional drainage units 21 that come into contact with each other, there are insertion holes 24 respectively. The insertion holes 24 are regular circular through holes. A reinforcing rib 25 is provided between two adjacent three-dimensional drainage units 21. The reinforcing rib 25 is made of high-strength plastic or stainless steel. The reinforcing rib 25 is connected to the three-dimensional drainage unit 21 through the insertion holes 24. The reinforcing rib 25 is used to realize the connection and fixation between adjacent three-dimensional drainage units 21.
[0028] Multiple protruding structures 26 are provided on the upper and lower inner walls of the three-dimensional drainage channel 22. The protruding structures 26 can increase the turbulence effect of the water flow, promote the discharge of impurities in the three-dimensional drainage channel 22, and prevent blockage. The protruding structures 26 are circular, triangular or square, with a height of 1mm-5mm and a spacing of 2mm-10mm.
[0029] See attached document Figure 3 The intermediate support layer 3 has a grid structure made of high-strength plastic or metal wire. The grid structure of the intermediate support layer 3 can not only provide stable support for the three-dimensional drainage layer 2, preventing it from deforming or collapsing under external pressure and ensuring the smooth flow of drainage channels, but also has a certain degree of permeability, so as not to affect the normal flow of water. At the same time, the grid gaps of the intermediate support layer 3 can further increase the complexity of the drainage channels and improve the drainage capacity.
[0030] See attached document Figure 4 The bottom waterproof layer 4 is a multi-layer composite structure, consisting of a waterproof membrane layer 41, a reinforcing fiber layer 42, and a base layer 43 from top to bottom. The waterproof membrane layer 41 is made of polyvinyl chloride (PVC) polymer waterproof material with a thickness of 0.5mm-1.5mm, providing excellent seepage prevention and effectively preventing water from seeping into the building structure from the bottom. The reinforcing fiber layer 42 is woven from basalt fiber material with a thickness of 1mm-3mm, embedded between the waterproof membrane layer 41 and the base layer 43, enhancing the overall strength and tensile properties of the waterproof layer and preventing it from cracking under external forces. The base layer 43 is made of fiberglass material with a thickness of 5mm-15mm, providing a stable supporting foundation for the entire waterproofing and drainage board.
[0031] The lower surface of the base layer 43 is provided with multiple support feet 44, the height of which is 10mm-20mm. The support feet 44 are used to form a certain gap between the waterproof board and the contact surface below, thereby further enhancing the drainage effect.
[0032] In the technical solution adopted in this embodiment, the three-dimensional drainage layer 2 is composed of multiple hollow three-dimensional drainage units 21, forming a three-dimensional drainage channel 22 inside. Water guide holes 23 are opened on the side walls to connect the drainage channels to each other, forming a three-dimensional drainage network. This greatly increases the effective cross-sectional area of the drainage channels, improves drainage efficiency, and can quickly introduce and discharge accumulated water. At the same time, the inner wall of the three-dimensional drainage channel 22 is provided with a raised structure 26 to increase the turbulence effect of water flow, promote the discharge of impurities, prevent blockage, and further ensure smooth drainage. Reinforcing ribs 25 are provided between adjacent three-dimensional drainage units 21, and they are connected and fixed through insertion holes 24 to enhance the stability and firmness of the overall structure of the three-dimensional drainage layer 2, ensuring that it can maintain good drainage performance even in complex environments.
[0033] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
