Description

Technical Field

[0001] This utility model relates to the field of water conservancy technology, specifically to a casting mold for an irrigation canal and an irrigation canal. Background Technology

[0002] An irrigation district refers to an irrigated area with a reliable water source and a system of water diversion, transportation, and distribution channels and corresponding drainage ditches. Water canals are an important component of an irrigation district.

[0003] In existing irrigation canals, the construction process typically involves first casting two roughly L-shaped side walls that are positioned opposite each other. Then, a sand cushion is filled between the bottom of the two side walls, and finally, a base slab is cast on the sand cushion. This process results in two problems: firstly, the gap between the side walls and the base slab directly leads to the sand cushion layer, and secondly, it aligns with the gap between the sand cushion layer and the side walls. During use, water can easily seep into the sand cushion layer, causing sand loss, which in turn leads to the base slab becoming hollow and sinking, affecting its service life. On the other hand, the shape of the side walls makes the fabrication and installation of their formwork more complicated, resulting in greater construction difficulties. Utility Model Content

[0004] According to one aspect of the present invention, a casting mold for an irrigation canal is provided, comprising an outer frame that is fixedly disposed;

[0005] The inner frame is located inside the outer frame;

[0006] Several connecting columns are installed between the outer frame and the inner frame, fixing the inner frame inside the outer frame.

[0007] A casting cavity is formed between the outer frame and the inner frame, which can be filled with solidified material; the inner frame and several connecting columns are all made of biodegradable material.

[0008] This invention provides a casting mold for an irrigation canal. The casting mold consists of an outer frame, an inner frame, and several connecting columns, with a casting cavity formed between the outer and inner frames. Multiple casting molds are connected end-to-end and fixed at the desired canal location. A solidifying material is filled into the casting cavity of the casting mold. After the material solidifies, an irrigation canal is formed, enabling irrigation of the irrigation area. Furthermore, after the inner frame and connecting columns degrade, the surface of the irrigation canal has multiple pores that can capture and retain soil necessary for plant growth, facilitating plant root establishment and growth within the canal, thus promoting the formation of a stable aquatic ecosystem within the irrigation canal in the future.

[0009] In some implementations, both the inner contour of the outer frame and the outer contour of the inner frame are trapezoidal.

[0010] In some implementations, the inner contour of the outer frame and the outer contour of the inner frame are parallel.

[0011] In some implementations, the outer frame is made of waterproof material.

[0012] In some embodiments, a plurality of first grooves are provided at one end of the outer frame, and a plurality of first protrusions are provided at the other end of the outer frame, wherein the first protrusions can be fitted into the corresponding first grooves.

[0013] In some embodiments, a plurality of second grooves are provided at one end of the inner frame, and a plurality of second protrusions are provided at the other end of the inner frame, wherein the second protrusions can be fitted into the corresponding second grooves.

[0014] According to one aspect of the present invention, an irrigation canal is also provided, comprising a plurality of casting molds connected end to end, wherein a coagulant is filled in the casting cavity.

[0015] The water channel is formed by the solidification of a cohesive material, and the inner surface of the water channel has several holes.

[0016] In some embodiments, the cross-section of the water channel is trapezoidal, and the cross-section of the water channel is trapezoidal and slopes outward from bottom to top. The trapezoidal cross-section of the channel surface facilitates drainage and prevents sewage from overflowing during drainage. Attached Figure Description

The outer frame 1 is fixedly installed; the inner frame 2 is located inside the outer frame 1; the several connecting columns 3 are disposed between the outer frame 1 and the inner frame 2, and the connecting columns 3 fix the inner frame 2 inside the outer frame 1. A casting cavity 4 is formed between the outer frame 1 and the inner frame 2, and the casting cavity 4 can be filled with a setting material; the inner frame 2 and the several connecting columns 3 are all made of biodegradable materials. The setting material is preferably concrete.

[0022] Preferably, the inner contour of the outer frame 1 and the outer contour of the inner frame 2 are parallel.

[0023] Preferably, the outer frame 1 is made of waterproof material.

[0024] Preferably, a plurality of first grooves are provided at one end of the outer frame 1, and a plurality of first protrusions are provided at the other end of the outer frame 1, wherein the first protrusions can be fitted into the corresponding first grooves.

[0025] Preferably, a plurality of second grooves are provided at one end of the inner frame 2, and a plurality of second protrusions are provided at the other end of the inner frame 2, wherein the second protrusions can be fitted into the corresponding second grooves.

[0027] In some embodiments, the cross-section of the water channel is trapezoidal, and the cross-section of the water channel is trapezoidal and slopes outward from bottom to top. The trapezoidal cross-section of the channel surface facilitates drainage and prevents sewage from overflowing during drainage.

[0030] Combination Figure 2 Several casting molds are fixed in the required irrigation area, and adjacent casting molds are connected end to end, i.e., the first protrusion is embedded in the corresponding first groove, and the second protrusion is embedded in the corresponding second groove; the casting cavity 4 is filled with solidifying material; in order to ensure that the casting mold is subjected to uniform stress, the solidifying material can be injected in multiple times to avoid cracking of the casting mold under stress. After the solidifying material solidifies, a water channel is formed.

[0031] Combination Figure 3 During the use of the irrigation canal, the inner frame 2 and several connecting columns 3 will gradually degrade. After the connecting columns 3 degrade, multiple holes 5 will be formed on the inner surface of the irrigation canal. The holes 5 on the surface of the irrigation canal can capture and retain the soil needed for plant growth, which helps plants to take root and grow in the irrigation canal, thus contributing to the formation of a stable aquatic ecosystem in the irrigation canal in the future.
