Description

Technical Field

[0001] This utility model relates to the field of cement blanket technology, and in particular to a novel high-strength cement composite mat. Background Technology

[0002] Cement blankets have important applications in water conservancy projects such as dam seepage prevention, road slope protection, and municipal engineering projects such as ditch repair. Cement blankets, scientifically known as concrete canvas, are soft fabric impregnated with cement. When exposed to water, they undergo a hydration reaction and harden into a thin, waterproof, fireproof, and durable concrete layer. They possess numerous advantages and are used in many projects, primarily for waterproofing and slope protection. However, with the development of the industry, higher requirements have been placed on the strength, crack resistance, and resistance to impurity intrusion of cement blankets. Therefore, it is necessary to develop a new type of high-strength cement composite mat to meet these needs.

[0003] Existing cement blankets structurally consist of a base fabric layer, a cement coating, and simple fiber threads embedded within the base fabric layer. Some products also include a standard protective layer on the surface of the base fabric layer. The underlying principle is that the base fabric layer provides fundamental support, the cement coating undergoes a hydration reaction upon contact with water to form a hardened layer, thus providing a certain level of strength and waterproofing, the simple fiber threads within the base fabric layer primarily serve to initially connect the layers and prevent delamination, and the standard protective layer can reduce the direct erosion of the internal structure by the external environment to a certain extent.

[0004] However, the simple fiber threads in existing cement blankets are only distributed within the base fabric layer and do not form a structure that runs through the whole, resulting in limited tensile and tear resistance. When stress is generated by base settlement or temperature changes, it is difficult to effectively disperse the stress, making the hardened cement layer prone to cracking. Therefore, a new type of high-strength cement composite pad is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a novel high-strength cement composite pad, which aims to improve the problems of traditional cement products in the prior art being prone to cracking when the base layer settles or the temperature changes, and being easily affected by external impurities.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A novel high-strength cement composite mat includes a cement matrix layer, with rubber particle interlayers fixedly connected to both sides of the cement matrix layer, and non-woven geotextile fixedly connected to the sidewalls of the rubber particle interlayers.

[0008] As a further description of the above technical solution:

[0009] The nonwoven geotextile has internally fixed reinforcing threads, and the sidewalls of the nonwoven geotextile are coated with polyurethane.

[0010] As a further description of the above technical solution:

[0011] The reinforcing line sidewall penetrates the rubber particle interlayer and the cement matrix layer.

[0012] As a further description of the above technical solution:

[0013] The rubber granule interlayer is made by mixing and pressing waste rubber granules with an elastic adhesive, and is used for elastic cushioning.

[0014] This utility model has the following beneficial effects:

[0015] In this invention, the cement matrix layer is the core, bearing the main compressive load. When the base layer settles or temperature changes, generating stress, the rubber particle interlayers on both sides buffer and absorb the stress, reducing cracking of the cement matrix layer. The non-woven geotextile on the sidewalls of the rubber particle interlayer blocks external soil particles, preventing impurities from affecting each layer. Reinforcing threads penetrate the rubber particle interlayer and the cement matrix layer, improving the overall tensile and tear resistance and enhancing stability. The polyurethane coating on the sidewalls of the non-woven geotextile resists natural erosion, is anti-aging and weather-resistant. All components work together to ensure the stable operation of the composite pad, solving the problems of traditional cement products being prone to cracking when the base layer settles or temperature changes, and being easily affected by external impurities. The above technical solution improves the resistance to the external environment. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figure 1 and Figure 2This utility model provides an embodiment of a novel high-strength cement composite mat, comprising a cement matrix layer 1, which provides core structural support for the composite mat and bears the main compressive load. Rubber granule interlayers 2 are fixedly connected to both sides of the cement matrix layer 1. The rubber granule interlayers 2 buffer the stress caused by base settlement and temperature changes, protecting the cement matrix layer 1 and reducing cracking due to uneven stress. Non-woven geotextile 3 is fixedly connected to the sidewalls of the rubber granule interlayers 2, serving to block external... Soil particles enter the internal structure, serving as filters and separators. The non-woven geotextile 3 is internally fixed with reinforcing threads 4, which enhance the tensile and tear resistance of the composite mat, thereby improving structural stability. The sidewalls of the non-woven geotextile 3 are coated with polyurethane coating 5, which resists the erosion of natural environments such as ultraviolet rays and wind and rain, providing anti-aging and weather resistance. The sidewalls of the reinforcing threads 4 penetrate the rubber particle interlayer 2 and the cement matrix layer 1. The rubber particle interlayer 2 is made by mixing and pressing waste rubber particles with elastic adhesive, and serves as an elastic buffer.

[0022] Working principle: The cement matrix layer 1 serves as the core structure, bearing the main compressive load and providing basic strength support for the composite pad. When the base layer settles or experiences stress due to temperature changes, the rubber particle interlayers 2 on both sides of the cement matrix layer 1 act as a buffer, absorbing stress to protect the cement matrix layer 1 and reduce its cracking. The non-woven geotextile 3 on the sidewall of the rubber particle interlayer 2 filters and isolates external soil particles from entering the internal structure, preventing impurities from affecting the performance of each layer. The reinforcing threads 4 inside the non-woven geotextile 3 penetrate the rubber particle interlayer 2 and the cement matrix layer 1, improving the overall tensile and tear resistance of the composite pad and enhancing structural stability. At the same time, the polyurethane coating 5 on the sidewall of the non-woven geotextile 3 resists natural erosion such as ultraviolet rays and wind and rain, playing a role in anti-aging and weather resistance. The rubber particle interlayer 2, which is made by mixing and pressing waste rubber particles with elastic adhesive, further enhances the elastic buffering effect. The synergistic effect of all components ensures the stable operation of the composite pad.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
