This problem is particularly serious in winter, when freezing often occurs, making channel leakage more serious, causing serious impacts on residents' drinking water and agricultural irrigation. The importance of water resources cannot be ignored. In order to ensure the effective use of water resources, corresponding anti-freeze measures must be taken, which has become a necessary means to improve the local ecological environment.
[0003] Specifically, in order to prevent the frost heave damage of water transfer channels, existing technologies have optimized the design of existing water transfer channels, for example, measures such as strengthening the insulation structure, optimizing the water flow rate, and using new antifreeze materials are adopted on the basis of the structure of the existing water transfer channels. In addition, daily maintenance and management of water transfer channels are strengthened to timely discover and deal with various problems to ensure a stable supply of water resources.
[0004] However, although the existing technology has proposed and studied a variety of solutions to the problem of safe water delivery in water delivery channels in winter, for example, traditional auxiliary heating methods mainly include electric heating, pumping water to melt ice, channel insulation, and hydraulic regulation. However, the above methods only alleviate the problem to a certain extent, and there are still deficiencies in ensuring the stability of water delivery channels, which requires further optimization and improvement, especially in improving the anti-freezing capacity of water delivery channels, reducing the difficulty of channel structure maintenance, and extending the service life of water delivery channels. The existing technology still needs to be further improved. Summary of the invention

DETAILED DESCRIPTION
[0025] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.
[0026] like Figure 1-Figure 5 As shown, in the embodiment of the utility model, an open solar energy storage-auxiliary heat permeable ventilation pipe anti-freezing heave channel structure is proposed, which aims to improve the anti-freezing heave ability of the channel, reduce the maintenance difficulty of the channel structure, and extend the service life of the channel.
[0027] The anti-frost heave channel structure proposed in the embodiment of the utility model utilizes a through-wall pipe structure to effectively separate the channel from the base soil and leave sufficient deformation space between them. The heat generated by the heating wire is released to the external environment, thereby reducing the direct damage to the channel caused by the frost heave deformation of the base soil. In addition, the steel structure outside the through-wall pipe has greater strength and rigidity and has good anti-frost heave capability.
[0028] When the channel structure fails or is damaged, maintenance work becomes more convenient, which is conducive to regular maintenance, thereby extending the service life of the channel and greatly reducing economic losses. This solar-assisted heating through-wall anti-seepage and anti-frost heave channel structure makes full use of solar energy, a renewable resource, not only improving energy utilization efficiency, but also providing an effective anti-frost heave solution for cold regions, with significant practical value and broad application prospects.
[0029] like Figure 1 As shown, the anti-frost heave channel structure includes a truss structure, a concrete through-wall pipeline 10 and a solar energy auxiliary heating device.
[0030] like Figure 1 As shown, the truss structure is laid on the base soil 14 of the water conveyance channel. The truss structure is laid along the side slope and the bottom of the water conveyance channel. A channel for laying the concrete through-wall pipe 10 is provided in the truss structure. Multiple groups of truss structures are laid along the water conveyance direction of the water conveyance channel. A concrete lining plate 4 is laid on top of the truss structure. For example, the joints of the concrete lining plate 4 are filled with polyurethane gelling sealing material.
[0031] like Figure 1 Combination Figure 4 As shown, the light energy auxiliary heating device includes a solar power generation unit 1, a heating wire 11 and a storage battery 8. The solar power generation unit 1 is installed at the top of the slope of the water conveyance channel. The output end of the solar power generation unit 1 is connected to the charging end of the storage battery 8. The discharge end of the storage battery 8 is connected to the heating wire 11 through a wire 7. The heating wire 11 is arranged in a concrete through-wall pipe 10.
[0032] like Figure 2 As shown, the concrete through-wall pipe 10 is arranged in the channel of the truss structure. Holes 9 are arranged on the side wall of the concrete through-wall pipe 10.
[0033] like Figure 5 As shown, the truss structure is welded by steel sections 12. A channel for laying a concrete through-wall pipe 10 is provided in the middle of the truss structure. The steel structure has good thermal conductivity, and the solar power generation auxiliary heating system can transfer heat energy to the base soil 14, thereby reducing the frost heave deformation of the base soil 14.
[0034] According to a preferred embodiment of the present utility model, Figure 3As shown, the connection of the concrete through-wall pipes 10 in the same truss structure is provided with a rubber tube 5. Adjacent concrete through-wall pipes 10 are connected by the rubber tube 5. The steel sections 12 are connected by bolts 6 at the junction of the channel bottom and the channel slope.
[0035] like Figure 1 Combination Figure 3 As shown, a cover plate 3 is provided at the end of the truss structure. The cover plate 3 is connected to a concrete lining plate 4.
[0036] like Figure 1 As shown, the solar power generation unit 1 is installed on the top of the slope of the water delivery channel through the support rod 13. Figure 1 Combination Figure 4 As shown, a temperature controller 2 is provided between the heating wire 11 and the storage battery 8. Intelligent regulation by the temperature controller 2 can achieve optimized complementarity between the storage battery 8 and solar power generation, effectively solve the problem of instability of solar power generation, and extend the power supply time. It provides an innovative long-term auxiliary heating and anti-freezing solution for channels in arid and cold areas, ensures the stable operation of channels in cold environments, improves energy utilization efficiency, and reduces the impact on the environment, which has important practical value and broad application prospects.
[0037] For example, the temperature controller 2 is buried in the base soil 14. When the temperature of the base soil 14 rises to or equals 0°C, the work will be divided: one solar power generation unit 1 is responsible for charging the storage battery 8, while the other solar power generation unit 1 directly supplies power to the heating wire 11. When the light is insufficient and the temperature is below 0°C, the storage battery 8 will take over the power supply task and convert the stored electrical energy into heat energy.
[0038] When in use, the steel structure design enables effective transfer of heat energy to the base soil 14, which helps to alleviate the frost heave deformation of the base soil 14, thereby protecting the channel from the damage caused by low temperature frost heave. This innovative design that integrates solar power generation and anti-frost heave functions not only improves the energy self-sufficiency of the channel, but also enhances the stability of the channel structure and prolongs its service life. It is a forward-looking technological advancement in the field of water conservancy and transportation.
[0039] Especially in the northwest of my country, there are abundant solar energy resources that can be effectively used for a long time. Although the conversion efficiency of solar energy has reached a maximum of 33.9%, there is still a large amount of light energy that can be converted into other forms of energy. The solar power generation auxiliary heating anti-freeze heave system is designed to prevent the channel from freezing in extreme low temperature environments, thereby avoiding damage to the channel slope. This system not only improves energy utilization, but also enhances environmental protection, ensures the stable operation of the channel in cold areas, and has good economic benefits.
[0040] The truss structure is used to support the channel, leaving enough deformation space for the deformation of the base soil 14 due to frost heave, avoiding the channel lining plate from contacting the base soil 14 over a large area, thereby greatly reducing the degree of frost heave damage to the channel. At the same time, space is left in the truss structure to facilitate regular inspection, maintenance and garbage removal by inspection personnel, which can effectively protect the integrity of the channel, thereby extending its service life and reducing economic losses.
[0041] The concrete through-wall pipe 10 forms a through-wall ventilation pipe by opening a hole 9 on the pipe wall of the concrete pipe. The electric heating wire 11 is placed in the through-wall ventilation pipe, and the generated heat is released to the external environment through the hole 9 on the pipe wall. This design not only improves the ventilation efficiency of the structure, but also helps to keep the inside of the pipe warm in a low-temperature environment, thereby effectively preventing the frost heave problem caused by the cold in the pipe, ensuring the stability and service life of the pipe. This design further improves the anti-freeze performance of the channel by means of light energy auxiliary heating. By combining light energy with steel structure, the anti-freeze heave ability of the channel is improved, while the difficulty of maintenance is reduced and the service life of the channel is extended.
[0042] The present invention is not limited to the specific technical solutions described in the above embodiments. In addition to the above embodiments, the present invention may also have other implementation modes. For those skilled in the art, any technical solutions formed by any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
