Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering facilities technology, and in particular to a basalt fiber composite material water channel. Background Technology

[0002] While traditional concrete or metal water channels have high structural strength, concrete water channels are prone to cracking and leakage; metal water channels have high maintenance costs and weak resistance to aging, alkali, and corrosion.

[0003] Basalt fiber composites are an advanced engineering material composed of basalt fibers as reinforcement (skeleton) and a matrix (adhesive). The role of the matrix is ​​to firmly bond the fibers together and transfer and distribute the load. Depending on the application, epoxy resin, unsaturated polyester resin, plastic, cement or metal can be selected as the matrix to form basalt fiber composites with different properties. Utility Model Content

[0004] In view of this, and to address the problems of traditional concrete canals being prone to cracking and leakage, and metal canals having high maintenance costs and weak aging and corrosion resistance, this utility model proposes a basalt fiber composite material canal. Based on the application characteristics of the canal, it is designed as a composite layer structure including an inner impermeable layer and an outer load-bearing layer. The impermeable layer has a smooth surface, low frictional resistance, high fluid transport efficiency, and excellent resistance to acid and alkali corrosion, preventing fluid from corroding and damaging the canal, thus preventing cracking and seepage. The load-bearing layer has high stiffness, enhancing the structural stability and support strength of the canal body.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a basalt fiber composite material water channel, comprising a water channel body with a composite layer structure, wherein the composite layer structure includes an inner impermeable layer and an outer load-bearing layer, and the water channel body is prepared by injection molding process, wherein the impermeable layer and the load-bearing layer are integrally formed.

[0006] Furthermore, the thickness ratio of the load-bearing layer to the impermeable layer is 7:3.

[0007] Furthermore, one end of the water channel body is provided with a protrusion along the circumference, and the other end is provided with a groove that matches the protrusion. The water channel body is connected to another water channel body by the fitting of the protrusion and the groove.

[0008] Furthermore, the cross-sectional shape of the main body of the water channel is U-shaped.

[0009] Furthermore, the top surface of both sides of the main body of the water channel is provided with vertically downward reinforcing crossbeam slots for installing external crossbeams.

[0010] Furthermore, baffles are provided vertically upward along the outer edges of the top surfaces on both sides of the main body of the water channel, and external cover plates are installed between the baffles.

[0011] Furthermore, the main body of the water channel is provided with circumferential reinforcing bars along its outer perimeter. The bottom surface of the circumferential reinforcing bars is a plane. There are multiple circumferential reinforcing bars, which are evenly distributed along the length of the main body of the water channel.

[0012] Furthermore, a supporting reinforcement bar is provided vertically downward on the outer bottom surface of the main body of the water channel between adjacent circumferential reinforcement bars. The bottom surface of the supporting reinforcement bar is coplanar with the bottom surface of the circumferential reinforcement bar. The supporting reinforcement bar is a strip perpendicular to the two circumferential reinforcement bars or a composite shape including a strip one, a ring and a strip two connected in sequence. The strip one and the strip two are perpendicular to the two circumferential reinforcement bars and are located on the same straight line.

[0013] Furthermore, a pair of arcs extend outward from the outer periphery of the left and right ends of the ring, and the pair of arcs are symmetrical with respect to the center of the ring.

[0014] Furthermore, the impermeable layer is formed by mixing epoxy resin, basalt fiber and polymer modified material, and the load-bearing layer is formed by mixing epoxy resin, basalt fiber and cement.

[0015] Compared with the prior art, the beneficial effects of the basalt fiber composite material water channel of this utility model are: 1. This utility model adopts injection molding process to integrally form a water channel with a composite layer structure. The water channel includes an inner seepage-proof layer and an outer load-bearing layer, which makes the inner wall of the water channel that participates in the transportation of fluid wear-resistant, acid and alkali corrosion resistant and aging resistant. At the same time, the load-bearing layer makes the main body of the water channel both rigid and structurally stable, and not easy to crack and leak.

[0016] 2. The seepage-proof layer described in this utility model has excellent hydraulic performance.

[0023] The top surface of both sides of the main body 1 of the water channel is provided with a vertically downward reinforcing crossbeam slot 15 for installing external crossbeams. The crossbeams can provide support and reinforce the stability of the U-shaped structure.
