AI Technical Summary
When prefabricated rectangular channels are connected at angles other than 90° or 180°, local cast-in-place and local cutting methods are used, which may result in loose connections, rough joint surfaces, leakage risks, and poor appearance.
The steel wire rubber rectangular channel, including U-shaped groove, pressure strip, L-shaped plate, nuts, fastening bolts and expansion bolts, takes advantage of the deformation performance of the rubber accordion plate and the steel wire reinforcement structure to achieve tightness and smoothness of connections at different angles.
It ensures that the connection surface is tight and leak-free, improves construction efficiency and aesthetics, adapts to changes in different connection angles, and maintains smooth water flow.

Abstract
Description
Technical Field
[0001] The invention relates to a rectangular channel, in particular to a node connection component for a flat-interface prefabricated assembled concrete rectangular channel. Background Art
[0002] In the actual application of precast concrete rectangular channels, the plane layout of the irrigation channels is affected by the existing ditch direction and the requirements of land and resources management. It is impossible for the rectangular channels to achieve 90° and 180° connections completely on the plane. Once the 90° and 180° connections cannot be achieved, gaps will appear in adjacent rectangular channel sections (2m / section), and leakage points will appear in the irrigation and drainage system. The usual practice is to use local cast-in-place and local cutting and docking solutions to solve the problem. Local cast-in-place has the problems of thin component wall, difficult quality control, poor combination of prefabrication and cast-in-place, long curing time, impact on construction period, poor appearance, etc.; local cutting and docking has the problems of difficult cutting, low precision, and uneven joint surface, which lead to leakage risks and poor appearance. Summary of the Invention
[0003] In order to solve the problems of loose connection, rough joint surface and leakage caused by the partial casting and partial cutting and docking method in the existing agricultural canal construction, the present invention provides a steel wire rubber rectangular canal.
[0004] The technical solution adopted by the present invention to solve the above problems is:
[0005] A steel wire rubber rectangular channel, which consists of a U-shaped groove, a pressure strip, an L-shaped plate, a nut, a fastening bolt and an expansion bolt. The U-shaped groove is made of a rubber accordion plate, and each vertical side of the U-shaped groove is equipped with a pressure strip and an L-shaped plate. The pressure strip is in contact with the outer wall of the U-shaped groove, and the short side of the L-shaped plate is in contact with the pressure strip. Fastening bolt holes are opened every 150 mm on the short side of the L-shaped plate, and nuts are welded on the outside of the fastening bolt holes. The fastening bolts are threadedly connected to the nuts and then fastened to the pressure strip; expansion bolt holes are opened every 150 mm on the long side of the L-shaped plate, and the expansion bolts pass through the expansion bolt holes.
[0006] Furthermore, steel wire is added into the rubber accordion plate.
[0007] Furthermore, the length of the pressure strip is the same as the height of the U-shaped groove.
[0008] Furthermore, the length of the L-shaped plate is the same as the height of the U-shaped groove.
[0009] Compared with the prior art, the present invention has the following beneficial effects:
[0010] 1. The present invention uses rubber accordion plates to make U-shaped grooves. The deformation performance of the V-shaped redundant structure of the accordion plates can adapt to the changes in different connection arrangement angles of the concrete rectangular channel plane. The connection surface between the U-shaped groove and the concrete rectangular channel is tight and smooth without leakage, which significantly improves the reliability of the structural connection and ensures the construction efficiency of the concrete rectangular channel.
[0011] 2. Adding steel wire to the rubber accordion board can ensure that when the accordion board is bent at different angles on the plane, its rectangular cross-section can remain unchanged, thereby ensuring that it has no effect on the water flow when used in conjunction with the concrete rectangular channel.
[0012] 3. The groove shape of the U-shaped groove of the present invention can be designed to match the groove shape of the assembled concrete rectangular channel, the purpose of which is to complete a smooth connection and good overall aesthetics. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Specific implementation method 1: Combination Figures 1 to 5This embodiment describes a U-shaped channel 1, a bead 2, an L-shaped plate 3, nuts 4, fastening bolts 5, and expansion bolts 6. The U-shaped channel 1 is made of a 6mm thick rubber accordion plate and has a length of 1000mm. Each vertical side of the U-shaped channel 1 is equipped with a bead 2 and an L-shaped plate 3. The bead 2 is aligned with the outer wall of the U-shaped channel 1, and the short side of the L-shaped plate 3 is aligned with the bead 2. Fastening bolt holes 31 are provided every 150mm along the short side of the L-shaped plate 3. Nuts 4 are welded to the outside of the fastening bolt holes 31. The fastening bolts 5 are threadedly connected to the nuts 4 and then fastened to the bead 2. Expansion bolt holes 32 are provided every 150mm along the long side of the L-shaped plate 3. Expansion bolts 6 pass through these holes. The long side of the L-shaped plate 3 is aligned with the side wall of the concrete rectangular channel 7 to be connected. The expansion bolts 6 connect the L-shaped plate 3 to the concrete rectangular channel 7. Steel wire is added to the rubber accordion plate. This arrangement ensures that the rectangular cross-section of the rubber accordion panel remains stable when bent at various angles. The length of the bead 2 is the same as the height of the U-shaped channel 1. Bead 2 is a steel strip with a wall thickness of 4mm and a width of 40mm. The length of the L-shaped plate 3 is the same as the height of the U-shaped channel 1. The L-shaped plate 3 is made of mild steel with a wall thickness of 5mm and a side length of 40mm x 100mm.
