Description

Technical Field

[0001] The utility model relates to the technical field of construction and civil engineering, in particular to a green prefabricated concrete face protection. Background Art

[0002] The internal concrete structure of traditional slope protection panels is often an integral structure, which is prone to uneven concrete pouring and a long curing time. At the same time, some areas have poor curing effects and are easily washed away by rainwater, resulting in loss. As a result, the slope protection panel structure cannot fit firmly with the slope, affecting the reinforcement effect of the slope. Utility Model Content

[0003] In order to solve the technical problems mentioned in the background technology, the utility model provides a green precast concrete face.

[0004] The utility model adopts the following technical solution: a green precast concrete face, comprising a base material layer, a waterproof layer, a cement layer, and a fireproof layer; the base material layer is a polypropylene and polyethylene composite fiber layer; the waterproof layer is entirely coated on the upper surface of the base material layer; the waterproof layer is a polyvinyl chloride layer; a fireproof layer is laid between the base material layer and the waterproof layer; the fireproof layers are arranged in a crisscross pattern to form a plurality of square filling spaces on the base material layer for pouring to form a cement layer; the cement layer forms a plurality of solidified units after solidification; the cement layer is a dry concrete mixed layer.

[0005] Furthermore, the thickness of the substrate layer is 10-15 mm.

[0006] Furthermore, the overall thickness of the cement layer is 15-30 mm.

[0007] Furthermore, the gap between the two curing units is 0.5-0.8 mm.

[0008] Compared with the existing technology, the advantages of the present invention are: the green precast concrete protective surface designed by the present invention adopts a fireproof layer arranged crisscross on the base material layer to form a number of square filling spaces for pouring to form a cement layer. After the cement layer is solidified, a number of solidification units are formed. Each solidification unit is implemented separately, the pouring is more uniform, the internal structure is more stable, and several supporting force points can be formed on the slope surface, thereby improving the fit and stability with the slope and greatly improving the service life.

[0014] In order to facilitate those skilled in the art to understand the technical solution of the present invention, the following is further described with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0015] In the following detailed description, for ease of explanation, numerous specific details are set forth to provide a comprehensive understanding of the embodiments of the present invention. However, it will be apparent that one or more embodiments may be practiced without these specific details. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concepts of the present invention.

[0016] like Figure 1-3 As shown, the green precast concrete protective surface involved in the present invention includes a substrate layer 1, a waterproof layer 5, a cement layer 3, and a fireproof layer 4. The substrate layer 1 is a composite fiber layer of polypropylene and polyethylene. In specific implementation, the thickness of the substrate layer 1 is 10-15 mm. The substrate layer 1 uses high-strength composite fibers as the substrate, so that the protective surface has high compression, tension and impact resistance. The waterproof layer 5 is coated on the upper surface of the substrate layer 1 as a whole. The waterproof layer 5 is a polyvinyl chloride layer, which can effectively prevent moisture from penetrating into the interior of the substrate layer 1, ensuring the normal hardening and service life of the cement layer. A fireproof layer 4 made of flame-retardant material is laid between the substrate layer 1 and the waterproof layer 5. The fireproof layer 4 is arranged in a crisscross pattern to form a number of square filling spaces on the substrate layer 1 for pouring to form a cement layer 3. The overall thickness of the cement layer 3 is 15-30 mm. After the cement layer 3 is cured, a number of solidification units 2 are formed, and the gap between two solidification units 2 is 0.5-0.8 mm. The cement layer 3 is a dry concrete mixing layer.

[0017] To sum up, the green precast concrete face designed by the present invention adopts a fireproof layer arranged in a crisscross pattern on the base material layer 1 to form a plurality of square filling spaces for pouring to form a cement layer 3. After the cement layer 3 is cured, a plurality of solidification units 2 are formed. Each solidification unit 2 is implemented separately, and the pouring is more uniform, the internal structure is more stable, and a plurality of supporting force points can be formed on the slope surface, thereby improving the fit and stability with the slope and greatly improving the service life.

[0018] The above embodiments are merely descriptions of preferred implementation methods of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
