Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering and landscape water feature design technology, specifically to a prefabricated channel. Background Technology

[0002] With the continuous development of industrialized construction, people have increasingly higher requirements for engineering projects, demanding technological updates, efficient and high-quality design, quick and convenient construction, low carbon emissions and environmental protection, and controllable investment. Prefabricated channels, as a new construction method, are gradually attracting attention from the industry. Compared with traditional cast-in-place concrete culverts, prefabricated culverts exhibit unique advantages in many aspects, and are particularly suitable for water system construction, rain gardens, ecological revetments, and landscape irrigation systems in garden landscapes, offering advantages such as short construction cycles, minimal environmental impact, and flexible design.

[0003] Compared to cast-in-place construction, prefabricated canals reduce negative environmental impacts and better meet the requirements of green construction, such as land conservation, energy conservation, material conservation, water conservation, and environmental protection. They help reduce noise, prevent dust, minimize environmental pollution, promote cleaner transportation, reduce site disturbance, and conserve resources such as water, electricity, and materials. Adhering to the principles of sustainable development, they shorten construction time and improve project quality. This new construction technology effectively solves the problems existing in traditional construction methods and is particularly suitable for the comprehensive needs of modern landscape design in terms of ecology, aesthetics, and functionality.

[0004] However, current prefabricated channels suffer from unreliable joint sealing, often requiring cement mortar filling and coating at the joints, which makes construction difficult, results in low sealing performance, and poor water-stopping effect. In landscape projects, this can easily lead to problems such as water system leakage and damage to the landscape effect. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0032] Example: like Figures 1-10 As shown, this utility model provides a prefabricated channel, which includes: a plurality of channel 10, a first waterstop 20 and a protective cover plate 30. The channel 10 is a precast reinforced concrete structure consisting of a base slab 11 and a wall 12; support steps 40 and overlapping inverted steps 50 are respectively provided at the beginning and end of the channel 10. The supporting step 40 includes: a first supporting inclined surface 41 and a supporting plane 42; The first supporting inclined surface 41 is provided with a first water-stop groove 43, and the supporting plane 42 at the bottom plate 11 is provided with a plurality of downwardly extending frustum grooves 44. The overlapping step 50 includes: a first overlapping inclined surface 51 and an overlapping plane 52; The first overlapping inclined surface 51 matches the first supporting inclined surface 41. The first overlapping inclined surface 51 and the first water-stop groove 43 are spliced ​​and matched at a flat surface. The overlapping plane 52 is provided with a limiting frustum 53 that corresponds one-to-one with the frustum groove 44. The limiting frustum 53 is larger at the top and smaller at the bottom. The shape and size of the frustum groove 44 match the limiting frustum 53. The supporting step 40 and the overlapping inverted step 50 are matched and spliced ​​together to restrict the displacement between adjacent channel sections, so as to achieve a tight connection of the nodes; The top inner side of the two side walls 12 of the channel 10 is provided with a sunken support slot 13; The first waterstop 20 is installed in the first waterstop groove 43. The first waterstop 20 is used to seal the joint between the bottom plate 11 and the wall 12 of the adjacent channel. The protective cover plate 30 is installed inside the support groove 13.

[0033] like Figure 9 , Figure 10 As shown, the angle α between the axis of the limiting frustum 53 and the generatrix is ​​≥45°, and the angle θ between the inclined surface of the first supporting inclined surface 41 and the vertical direction satisfies α-10°≤θ≤α+10°.

[0034] like Figure 1 , Figure 2 As shown, the supporting step 40 further includes: a second supporting inclined surface 45; The second support slope 45 is provided with a second water-stop groove 46; The overlapping step 50 further includes: a second overlapping slope 54; The second overlapping inclined surface 54 matches the second supporting inclined surface 45, and the position where the second overlapping inclined surface 54 and the second waterstop groove 46 are spliced ​​and matched is a flat surface; The second waterstop 46 is equipped with a second waterstop 21, which is used to perform secondary waterstop sealing on the joint between the bottom plate 11 and the wall 12 of the adjacent channel.

[0035] like Figure 1 , Figure 2 As shown, the first support inclined surface 41 and the second support inclined surface 45 are located at the two ends of the support plane 42, and the inclination angles of the two inclined surfaces are the same.

[0036] like Figure 1 , Figure 2 As shown, the inner wall of the base plate 11 and the inner wall of the wall 12 are rounded.

[0037] like Figures 1-5 As shown, the wall 12 has multiple hoisting holes 14 at the same height, and the number of hoisting holes 14 on a single section of the channel 10 is no less than four.

[0038] A steel sleeve is embedded in the lifting hole 14. The outer diameter of the steel sleeve matches the inner diameter of the lifting hole 14, so as to realize the interference connection between the steel sleeve and the lifting hole 14. The inner diameter of the steel sleeve is larger than the diameter of the steel wire rope used for lifting.

[0039] The hoisting hole 14 penetrates the wall 12 through the mesh of the steel mesh inside the wall 12, and the steel mesh around the hoisting hole 14 can effectively ensure the structural stability of the hoisting hole 14.

[0040] Both the first waterstop 20 and the second waterstop 21 are made of water-swellable waterproof rubber strips.

[0041] like Figures 3-8 As shown, the protective cover plate 30 is a segmented precast reinforced concrete slab.

[0042] like Figures 6-8 As shown, the top surface of the protective cover plate 30 is provided with a plurality of ring ear grooves 31, and ring ears 32 are provided in the ring ear grooves 31. The top height of the ring ears 32 is lower than the top surface height of the protective cover plate 30, so that the ring ears 32 are hidden in the ring ear grooves 31 and are not exposed. This can realize the hoisting operation of the protective cover plate 30, and ensure that the ring ears 32 do not protrude from the top surface of the protective cover plate 30, which is conducive to the stacking and storage of the protective cover plate 30.

[0043] like Figure 8 As shown, the ring ear 32 is a wave-shaped component, and both ends of the ring ear 32 are pre-embedded in the protective cover plate 30.

[0044] In summary, compared with the prior art, the present invention has the following beneficial effects: In this embodiment of the present invention, the adjacent channels 10 of the prefabricated channel are spliced ​​together by the supporting steps 40 and the overlapping inverted steps 50. During the process of the limiting truncated cone 53 sliding along the inner wall of the corresponding truncated cone groove 44 until the insertion is completed, the relative parallel displacement between the first overlapping inclined surface 51 and the first supporting inclined surface 41 is very small, which greatly reduces the lateral pulling on the waterstop during the assembly process and avoids damage to the waterstop. In addition, the limiting effect of the limiting truncated cone 53 and the truncated cone groove 44 makes the adjacent channels 10 spliced ​​tightly, with strong sealing and excellent water-stopping effect. No grouting or painting is required, and construction is convenient.
