Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to an anti-frost heave channel. Background Technology

[0002] Water conveyance channels play a vital role in transporting water resources from water-sufficient areas to water-scarce areas, alleviating water shortage pressure in northern regions. However, northern my country is located at a low latitude and experiences cold winters, resulting in seasonal freezing and permanent freezing in some parts of the Northwest Plateau. This causes frost heave damage to the channels, leading to leakage during water transport and a cycle of repeated frost heave damage.

[0003] Among them, announcement number CN219973093U discloses a wind-powered, heat-assisted truss steel structure anti-seepage and frost-heave-resistant channel. The channel includes a truss structure, a panel structure, and wind-powered heating equipment. The truss structure is laid on the channel's foundation soil. The truss structure is arranged along the channel's slopes and bottom. Multiple sets of truss structures are arranged along the channel's extension. Adjacent truss structures are connected by square steel bars. The panel structure is laid on the truss structure and includes a geomembrane, a waterproofing plate, and a concrete lining plate. The wind turbine of the wind-powered heating equipment is installed at the top of the channel slope. The output end of the wind turbine is connected to the charging end of a battery. The discharging end of the battery is connected to heating wires via wires. The heating wires are arranged between the geomembrane and the waterproofing plate. This wind-powered, heat-assisted truss steel structure anti-seepage and frost-heave-resistant channel improves the channel's frost-heave resistance, reduces the difficulty of channel structure maintenance, and extends the channel's service life.

[0004] The device uses a steel structure to support the panel structure, improving the channel's resistance to frost heave and transferring some heat to the interior of the foundation soil, thus reducing frost heave deformation. However, in actual use, the depth of frost heave in the foundation soil is usually quite deep, and the bottom of the steel structure is in direct contact with the foundation soil without stable support. During long-term use, when the deep foundation soil undergoes frost heave deformation, the surface foundation soil will still settle and deform, thereby damaging the channel.

[0005] Therefore, it is necessary to invent an anti-frost heave channel to solve the above problems. Utility Model Content

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] This utility model provides, for example Figures 1 to 4 The illustrated anti-frost heave channel includes a steel structure support 1, which is U-shaped. Concrete formwork 16 is laid on the upper side of multiple sets of steel structure supports 1. Insulation cotton 18 is filled between two sets of steel structure supports 1. The bottom of the steel structure support 1 abuts against a first steel structure column 15. Support structures are provided at both ends of the steel structure support 1. The support structure includes a second steel structure column 2, a pouring hole 21, a support plate 22, an injection pipe 23, and a second threaded rod 25. The support plate 22 is located at the front and rear... Both ends are provided with second insertion holes 26, and support anchor rods 27 are inserted into the second insertion holes 26. The upper end of the second steel structure column 2 is fixedly connected to the lower surface of the support plate 22. The pouring hole 21 is opened on the side of the second steel structure column 2. The injection pipe 23 is fixedly connected to the upper surface of the support plate 22. The injection pipe 23 is provided with an inlet 24. The lower end of the inlet 24 is connected to the interior of the second steel structure column 2. The lower end of the second threaded rod 25 is fixedly connected to the upper surface of the support plate 22.

[0031] In the process of use, a channel is first excavated on the surface of the foundation soil. The first steel structure column 15 is inserted into the bottom of the channel. Then, the second steel structure column 2 is inserted into the surface of the foundation soil on both sides of the channel. The first steel structure column 15 and the second steel structure column 2 are located on the same vertical plane. Next, the steel structure support 1 is erected on the upper side of the first steel structure column 15 and the second steel structure column 2, which support the steel structure support 1. Then, concrete is injected into the interior 1 of the second steel structure column 2 through the injection pipe 23. Then, the concrete is pressure-driven to seep out from the pouring hole 21, so that the concrete forms a concrete foundation on the side of the second steel structure column 2 and the channel, which improves the stability of the steel structure support and reduces the impact of frost heave on the steel structure support 1. Then, insulation cotton is laid between multiple sets of steel structure supports 1. Finally, the concrete formwork 16 is laid on the upper side of the steel structure support 1.

[0032] See Figure 5 and Figure 6 Four sets of first connecting blocks 11 are fixedly connected to the lower ends of the left and right sides of the steel structure support 1. The surface of the first connecting block 11 is provided with a first insertion hole 12. The second threaded rod 25 is inserted into the first insertion hole 12. Four sets of second connecting blocks 13 are fixedly connected to the upper ends of the left and right sides of the steel structure support 1. The upper end of the second connecting block 13 is fixedly connected with a first threaded rod 14. The upper ends of the first threaded rod 14, the second threaded rod 25 and the support anchor rod 27 are all threaded with nuts. The left and right sides of the concrete formwork 16 are provided with connecting through holes 17. The first threaded rod 14 is inserted into the connecting through hole 17.

[0033] Specifically, when the steel structure support 1 is erected on the upper end of the second steel structure column 2, the second threaded rod 25 is inserted into the first insertion hole 12 and locked with a nut to secure the steel structure support 1 to the second steel structure column 2. Then, the support anchor rod 27 is inserted into the second insertion hole 26 and locked with a nut to further support the support plate 22 and improve the stability of the steel structure support 1. When laying the concrete formwork 16, the first threaded rod 14 is inserted into the connecting through hole 17 and locked with a nut to secure the concrete formwork 16 to the steel structure support 1.

[0034] The working principle of this utility model is as follows: In order to reduce the impact of deep soil frost heave on the channel and improve the channel's safety, a first steel structure column 15 is inserted under the steel structure support 1, and second steel structure columns 2 are inserted on both sides of the steel structure support 1. Concrete is injected into the interior of the second steel structure columns 2, and the concrete seeps out from the pouring hole 21 to the outside, forming a concrete foundation on the side of the channel and the side of the second steel structure columns 2. This reduces the impact of frost heave on the soil and increases the support strength of the second steel structure columns 2, thereby improving the stability of the steel structure support 1 and the channel, and enhancing the safety of the channel in use.
