Detailed Embodiments

[0020] The technical solutions of the present application will be clearly and completely described below with reference to the drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0021] An embodiment of the present application discloses a socket-assembled precast concrete trapezoidal channel. Refer to Figure 1, the socket-assembled precast concrete trapezoidal channel includes multiple channel base segments 10, multiple base segment connectors 20, and a set of paving plate assemblies 30. During assembly, the opposite sides of every two adjacent channel base segments 10 among the multiple channel base segments 10 can be aligned and contacted with each other, so that the multiple channel base segments 10 can be joined together to form a continuous channel structure for water conveyance. An inner concave area is formed on the outer wall of the end of each channel base segment 10. Each base segment connector 20 is inserted into the interconnected inner concave areas of two adjacent channel base segments 10, and the base segment connector 20 is clamped and fixed to the two channel base segments 10, so that the base segment connector 20 can limit the two adjacent channel base segments 10 and reduce the offset of each channel base segment 10 in the channel structure. The paving plate assembly 30 is laid on the inner bottom of the channel structure, and the paving plate assembly 30 covers the joint between every two adjacent channel base segments 10. A water-stop rubber layer is further provided on the outer side of the paving plate assembly 30, and the water-stop rubber layer is formed after the sealant filling the side seam between the paving plate assembly 30 and the surface groove 16 of the multiple channel base segments 10 solidifies. The setting of the paving plate assembly 30 can, on the one hand, be used to improve the anti-seepage ability of the inner bottom of the channel structure, and on the other hand, it can also compare whether there are large deviations in the joining of the channel structure when laying the paving plate assembly 30.

[0022] Refer to Figure 2 and Figure 3 , when the precast volume or precast weight of the channel base segment 10 is large, the channel base segment 10 can be divided into a first precast block 11 and a second precast block 12 for precasting. As shown in the figure, the overall shapes of the first precast block 11 and the second precast block 12 are symmetrical to each other, and an inner concave part 131 and a convex part 132 are respectively formed on the opposite sides of the first precast block 11 and the second precast block 12. The lengths of the inner concave part 131 and the convex part 132 are both equal to the length of the first precast block 11 or the second precast block 12, and the inner concave part 131 and the convex part 132 respectively include an equal number of inner grooves and outer protrusions. When combining the first precast block 11 and the second precast block 12 into the channel base segment 10, it can be completed by inserting and matching the inner concave part 131 and the convex part 132 with each other. Through the insertion and matching of multiple inner grooves and outer protrusions between the inner concave part 131 and the convex part 132, a labyrinth seal structure can be formed. When the water flowing downward flows in the labyrinth, due to the friction generated by the viscosity of the liquid, the flow rate slows down and the flow volume decreases. The frictional resistance effect is jointly composed of the frictional resistance along the flow path and the local frictional resistance between the flow paths in the labyrinth seal structure. In addition, when the fluid passes through the slit in the labyrinth seal structure, it will contract due to the influence of inertia, the cross-section of the flow bundle decreases, and further the seepage of water body will also be reduced.

[0023] Refer to Figure 2 and Figure 4, end grooves 14 are formed on the outer walls of the ends of the first precast block 11 or the second precast block 12, and the end grooves 14 on the first precast block 11 and the second precast block 12 constitute the concave area of the channel base section 10. A plurality of positioning blocks 15 are fixedly connected in each end groove 14. The plurality of positioning blocks 15 are spaced equidistantly along the height direction of the end groove 14, and the shape of the positioning block 15 is adapted to the shape of the end groove 14. The shape of the cross-section of the base section connecting part 20 is adapted to the shape formed by combining two communicating end grooves 14. During assembly, the base section connecting part 20 can be inserted therein, and a plurality of fastening grooves 21 formed on one side of the base section connecting part 20 facing the first precast block 11 or the second precast block 12 and cooperating with the positioning blocks 15 are used to make the base section connecting part 20 clamped in the concave area. The base section connecting part 20 can be made into an integral structure by injection molding.

[0024] Refer to Figure 2 , surface grooves 16 are formed on the inner bottom walls of the first precast block 11 or the second precast block 12. The surface grooves 16 penetrate through the ends of the first precast block 11 or the second precast block 12 along the length direction of the first precast block 11 or the second precast block 12, and the surface grooves 16 are used to cooperate with the installation of the paving plate assembly 30.

[0025] Refer to Figure 1 , the paving plate assembly 30 includes multiple paving plates with a thickness adapted to the depth of the surface groove 16. During assembly, two adjacent paving plates among the multiple paving plates can be laid in the surface grooves 16 of multiple sections of the channel base section 10 in contact with each other with their opposite sides aligned, and it is also necessary to make the joints between every two adjacent paving plates misaligned with the joints between every two adjacent channel base sections 10. Thus, the paving plates can cover the joints between every two adjacent channel base sections 10. In addition to filling sealant in the gaps between the paving plate assembly 30 and the surface groove 16, sealant can also be used to bond and fix every two adjacent paving plates.

[0026] In this embodiment, the socket-assembled precast concrete trapezoidal channel can be integrally arranged in a pre-dug trench, and concrete can be filled in the gap between the trench and the outside of the socket-assembled precast concrete trapezoidal channel for reinforcement.

[0027] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
