Description

Technical Field

[0001] This utility model relates to the field of water conservancy facilities technology, specifically to a corrugated steel plate structure water channel. Background Technology

[0002] With the continuous development of engineering technology, metal corrugated pipe technology has made significant progress and is widely used in urban municipal engineering, highway engineering and other fields. Steel corrugated materials have gradually come into people's view. Steel corrugated plates have the characteristics of high strength and light weight, which can effectively bear large loads and reduce the pressure of the structure's own weight on the foundation. They are suitable for various geological conditions. Their connection methods are simple and quick, and welding, bolt connection and other methods can be used to greatly shorten the construction time and improve the construction efficiency. Moreover, steel corrugated plates can be prefabricated in the factory and assembled on site according to actual needs. They have low requirements for the construction site and can adapt to different construction environments. In terms of seepage prevention, through reasonable sealing treatment, steel corrugated plate structure water channels can achieve good seepage prevention effect and effectively reduce water waste.

[0003] However, existing technologies have the following problems in practical use:

[0004] Existing corrugated steel plate water channels are assembled using a splicing method. The joints are fixed by various connectors. Even with sealing measures at the joints, it is difficult to completely avoid the risk of leakage. Since the joints are not integrally formed, the sealing material may crack or fall off when subjected to complex external forces, leading to water leakage at the joints. This not only wastes water resources but may also cause sewage leakage and environmental pollution. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figures 1 to 5 This utility model embodiment provides a corrugated steel plate structure water channel. This embodiment improves the structure of the corrugated steel plate structure water channel, making it integrally forged, further ensuring overall stability. Specifically, it facilitates installation and provides greater overall stability. Taking the corrugated steel plate structure water channel as an example, as a preferred solution in this embodiment, the water channel is specifically a corrugated steel plate structure water channel. Compared to existing spliced ​​corrugated steel plate structure water channels, the integrally forged structure avoids structural instability caused by loose connectors.

[0027] Please see Figures 1 to 5 This utility model provides a technical solution: a corrugated steel plate structure water channel, which is mainly used in water conservancy facilities for transporting water sources.

[0028] The water channel component 1 includes a corrugated steel plate 101, a corrugated plate 102, and an upper transverse edge 103. The water channel component 1 is integrally forged from the side and bottom edges of the corrugated steel plate 101 along the transverse corrugation direction. The corrugated plate 102 is fixedly installed on the inner bottom wall of the corrugated steel plate 101. A lower folded edge 5 for limiting is fixedly connected to the outer side of the upper transverse edge 103 downward.

[0029] In this embodiment, the water channel assembly 1, corrugated steel plate 101, corrugated plate 102, and upper transverse edge 103 are arranged in a coordinated manner. Since the water channel assembly 1 is integrally forged and formed by the side and bottom edges of the corrugated steel plate 101 along the transverse corrugation direction, forming a whole, no additional connecting components are required. This further ensures the integrity and stability of the water channel assembly 1 when it is impacted by water flow, effectively reducing the risk of local deformation or collapse of the water channel. Furthermore, the corrugated plate 102 further reduces the scouring and wear of the bottom of the water channel by deposited sand and gravel.

[0030] In the above embodiment, as a preferred solution, the corrugated steel plate 101 has multiple round holes 3 for connection at both ends of its longitudinal direction. Two adjacent water channel components 1 are fixedly connected by bolts through the round holes 3. Long strip sealing gaskets 8 or sealing fillers are provided at the edge connection. Long strip sealing gaskets 8 and sealing fillers can also be used simultaneously to increase the sealing performance. The round holes 3 facilitate the positioning and fixing of multiple water channel components 1 when they are installed and connected by workers, making it easier for workers to assemble multiple water channel components 1 together. The sealing gaskets 8 or sealing fillers play a sealing role to prevent leakage.

[0031] In the above embodiment, as a preferred solution, a screw 4 for fixing is inserted into the upper end of the corrugated plate 102. The screw 4 passes through the upper end of the corrugated plate 102 and is threaded to the inner bottom wall of the corrugated steel plate 101. The screw 4 can be a dovetail screw, a rivet, or other bolt connection. By setting the screw 4, it is easier for workers to fix the corrugated plate 102 more firmly above the inner bottom wall of the corrugated steel plate 101.

[0032] In the above embodiment, as a preferred solution, there is a fixing hole 2 in the middle of the longitudinal direction of the upper horizontal edge 103 on both sides. There can also be multiple positioning holes 2. A tie rod 6 is fixedly installed at the upper end of the upper horizontal edge 103 in the middle of the positioning holes 2 on both sides. The two ends of the tie rod 6 have corresponding holes corresponding to the positioning holes 2. An anchor rod 7 passes through the upper end of the tie rod 6 and through the fixing hole 2. Then the anchor rod 7 is fixed into the concrete. The lower end of the anchor rod 7 can be a pointed tip or a right-angled L-shape. Through the setting of the tie rod 6 and the anchor rod 7, the overall firmness and strength of the water channel are further guaranteed, and there will be no deformation.

[0033] Example 1: In the above examples, as a preferred option, the cross-section of the water channel can be trapezoidal. The trapezoidal shape makes the bottom of the water channel wider, which can provide more stable support, withstand greater water pressure and ground load, and is less likely to deform or collapse under the long-term action of water flow and when facing possible external pressure, thus ensuring the safety and durability of the water channel structure.

[0034] Example 2: In the above examples, as a preferred embodiment, the cross-section of the canal can be semi-circular. The semi-circular cross-section has no sharp edges or corners, allowing water to flow more smoothly within the canal. This effectively reduces turbulence and eddies, lowers flow resistance, and thus improves flow velocity and water conveyance efficiency. According to hydraulic principles, under the same water flow area, a semi-circular canal has the shortest wetted perimeter and the largest hydraulic radius, resulting in the most ideal flow conditions. It can convey a larger flow rate with a smaller head loss. Due to the relatively high flow velocity and stable flow pattern, impurities such as silt carried in the water are less likely to deposit at the bottom of the canal, reducing the possibility of siltation and thus lowering the dredging and maintenance costs of the canal, ensuring the long-term stable water conveyance capacity of the canal.

[0035] Example 3: In the above examples, as a preferred solution, the cross-section of the water channel can be rectangular. A rectangular cross-section can make full use of space and better adapt to specific terrain and layout requirements when land resources are limited. The regular right-angle shape makes it easier to measure, cut and splice during the processing and installation of corrugated steel plates. Construction personnel can operate more conveniently according to the design dimensions, reducing the complexity of the construction process and improving construction efficiency. The regular internal space of the right-angled water channel makes it easier for maintenance personnel to enter the water channel for inspection, repair and cleaning. Maintenance personnel can walk and operate more conveniently in the right-angled passage, and it is also more convenient to use tools, so as to discover and deal with problems inside the water channel in a timely manner.

[0036] In this invention, the working steps of the device are as follows:

[0037] 1. First, the side and bottom edges of the corrugated steel plate 101 along the transverse corrugation direction are manufactured by an integral forging process to ensure that the structure has no connecting parts and enhance the overall stability. During the forging process, multiple round holes 3 for connection are opened at both ends of the longitudinal edge of the corrugated steel plate 101. Long strip sealing gaskets 8 are set at the edge connection. Two adjacent water channel components 1 are fixed by bolts through the round holes 3. After the fixing is completed, the edge can be filled with sealant.

[0038] 2. Secondly, the corrugated plate 102 is processed and formed according to the design dimensions, and mounting holes are pre-set at its upper end to facilitate subsequent fixing to the inner bottom wall of the corrugated steel plate 101 with screws 4.

[0039] 3. Then, at the construction site, the installation area is leveled and the foundation is treated to ensure that the ground bearing capacity meets the requirements. The individual water channel component 1 is transported to the installation position. First, the lower end of the corrugated plate 102 is aligned with the inner bottom wall of the corrugated steel plate 101. The screw 4 is passed through the mounting hole at the upper end of the corrugated plate 102 and threaded into the pre-set threaded hole in the inner bottom wall of the corrugated steel plate 101. The screw 4 is tightened to make the corrugated plate 102 firmly fixed, which plays the role of guiding water flow and reducing scouring.

[0040] 4. Finally, insert anchor rods 7 into the tie rods 6 at the upper end of the upper horizontal edge 103, so that the anchor rods 7 pass through the tie rods 6 and the upper horizontal edge 103, and tighten them with nuts to further enhance the stability of the canal structure. Repeat the above steps to complete the installation and laying of the entire canal.

[0041] Corrugated steel plate 101 is typically made of galvanized magnesium-aluminum corrugated steel plate, steel corrugated plate, or stainless steel corrugated plate. Depending on the actual project requirements, corrugated steel plate 101 can also be made of plastics (PVC, PVC-U, PP-R), high-density polyethylene (HDPE), fiber-reinforced composite plastic (FRP, commonly known as fiberglass), and other materials. Common models of corrugated steel plate 101 are: 68mm corrugation pitch and 13mm corrugation height, 80mm corrugation pitch and 14mm corrugation height, and 125mm corrugation pitch and 25mm corrugation height. The length of a single section of water channel component 1 is commonly 30mm-150mm, and the width (inner wall bottom) is 40mm-300mm. Different models of water channel component 1 are selected according to different construction scenarios.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
