Description

Technical Field

[0001] This utility model relates to the field of water conservancy facilities technology, specifically to a water conservancy rapid flow channel. Background Technology

[0002] The overflow channel, also known as the spillway of a hydraulic power station, is mainly used to ensure the normal water volume in the downstream river channel, thereby guaranteeing the normal production and living needs of the downstream area. Current overflow channels are assembled from multiple precast concrete components, which greatly shortens the construction period and facilitates subsequent maintenance. However, the existing precast concrete components use a simple snap-fit ​​design, with the joints sealed using sealant. Over time, this makes them prone to separation due to water erosion. Utility Model Content

[0003] The purpose of this invention is to provide a hydraulic rapid flow channel to further increase the tightness of the connection after multiple precast concrete components are assembled.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A hydraulic rapid flow channel includes multiple prefabricated channel components that can be assembled end to end. One end of the component is provided with an upper jaw plate that is flush with the inner wall of the prefabricated channel component, while the other end is provided with a lower jaw plate whose outer wall is flush with the outer wall of the prefabricated channel component and which is connected to the upper jaw plate.

[0006] The three adjacent outer surfaces of the maxillary plate are respectively provided with interconnected arc-shaped embedding grooves.

[0007] The mandibular plate has three adjacent inner surfaces each provided with interconnected semi-circular inserts.

[0008] Preferably, the mandibular plate has a limiting stop at its port section, and the limiting stop is fitted into a groove at the port section of the maxillary plate.

[0009] Preferably, the sidewall of the semi-circular insert is symmetrically provided with a plurality of equally spaced insert grooves, and an inlay block that can be inserted into the insert groove is fixedly provided in the arc-shaped insert groove.

[0010] Preferably, rectangular slots are formed on two adjacent horizontal surfaces of the inlay block, and rectangular blocks with a predetermined spacing are respectively provided on the inner walls of opposite sides of the rectangular slots.

[0011] Preferably, the precast trough is a precast concrete component.

[0012] In the above technical solution, the hydraulic rapid flow channel provided by this utility model has the following beneficial effects: multiple prefabricated channel parts are combined by snapping together the upper and lower jaw plates at the ends. During the snapping process, concrete or engineering structural adhesive is applied to the arc-shaped embedding groove in advance. Then, as the semi-circular embedding part is embedded into the arc-shaped embedding groove, the concrete or engineering structural adhesive is squeezed, causing the excess part to overflow from the arc-shaped embedding groove. Under the application of pressure, the overflowing excess part is spread evenly on the contact surface of the upper and lower jaw plates. Attached Figure Description

[0018] 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.

[0019] like Figure 1-2 As shown, a hydraulic rapid flow channel includes multiple prefabricated channel components 1 that can be assembled end to end. One end of the prefabricated channel component 1 is provided with an upper jaw plate 11 that is flush with the inner wall of the prefabricated channel component 1, while the other end is provided with a lower jaw plate 12 whose outer wall is flush with the outer wall of the prefabricated channel component 1 and which connects with the upper jaw plate 1 of an adjacent prefabricated channel component 1.

[0020] The maxillary plate 11 has three adjacent outer surfaces each having a connected arc-shaped insert groove 2;

[0021] The mandibular plate 12 has three adjacent inner surfaces each provided with a semi-circular insert 3 that is connected to each other.

[0022] Specifically, in the embodiment, the circumferential radius of the semi-circular insert 3 is one-quarter of the circumferential radius of the arc-shaped insert groove 2.

[0023] In the above technology, multiple prefabricated grooves 1 are combined by snapping together the upper jaw plates 11 and lower jaw plates 12 at the ends. During the snapping process, concrete or structural adhesive is applied to the arc-shaped embedding groove 2 beforehand. Then, as the semi-circular embedding part 3 is inserted into the arc-shaped embedding groove 2, the concrete or structural adhesive is squeezed out, causing the excess part to overflow from the arc-shaped embedding groove 2. Under the applied pressure, the overflowing excess part is spread evenly on the contact surface of the upper jaw plate 11 and lower jaw plate 12.

[0024] As a further embodiment of this utility model, the port section of the mandibular plate 12 is provided with a limiting stop 4, which is fitted into the groove 5 opened in the port section of the maxillary plate 11.

[0025] Specifically, in the embodiment, the limiting stop 4 and the groove 5 are fitted together to intercept the concrete or structural adhesive that overflows when pressure is applied, thus preventing the contact surface between the maxillary plate 11 and the mandibular plate 12 from overflowing.

[0026] As another embodiment of the present invention, the sidewall of the semi-circular insert 3 is symmetrically provided with a plurality of equally spaced insert grooves 31, and an inlay block 21 that can be inserted into the insert groove 31 is fixedly provided in the arc-shaped insert groove 2.

[0027] Specifically, in the embodiment, when the semi-circular insert 3 is embedded in the arc-shaped insert groove 2, the insert block 21 increases the contact area with the concrete or engineering structural adhesive located in the arc-shaped insert groove 2, thereby increasing the strength of the joint connection.

[0028] As a further embodiment of the present invention, rectangular grooves 22 are provided on two adjacent horizontal surfaces of the inlay block 21, and rectangular blocks 23 with a predetermined spacing are respectively provided on the inner walls of opposite sides of the rectangular grooves 22.

[0029] Specifically, when the semi-circular insert 3 is inserted into the arc-shaped insert groove 2, the insert block 21 will be inserted into the concrete or structural adhesive located in the arc-shaped insert groove 2. Then the concrete or structural adhesive will naturally fill into the rectangular groove 22, and the rectangular block 23 will further increase the contact area of ​​the concrete or structural adhesive located in the arc-shaped insert groove 2, thereby increasing the strength of the joint connection.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
