[0001] This utility model belongs to the field of water conservancy engineering technology, and in particular relates to a channel lining pouring construction bottom cushion layer reinforcement structure. Background Technology
[0002] Channel lining pouring refers to the engineering technology of pouring concrete, masonry, geomembrane, and other materials into the inner wall of channels for farmland irrigation and water conveyance, and forming a continuous and flat protective layer through construction procedures such as formwork, material placement, vibration, and curing. Its core purpose is to reduce leakage losses during channel water conveyance and enhance the resistance of the inner wall of the channel to water erosion.
[0003] In the construction of channel lining, the condition of the channel bottom bedding layer plays a decisive role in the stability and seepage prevention of the lining structure. Currently, the channel bottoms we use are mostly undisturbed soil foundations or simple sand and gravel bedding layers. Undisturbed soil is easily deformed by water flow erosion and seepage, and sand and gravel bedding layers are prone to particle loss under long-term hydraulic action. Therefore, it is necessary to design a channel bottom bedding layer reinforcement structure for channel lining construction. Using a base steel structure for reinforcement can enhance the overall bearing capacity and erosion resistance of the bedding layer, avoid seepage deformation of the undisturbed soil foundation and particle loss of the sand and gravel bedding layer, ensure a tight fit between the lining layer and the bedding layer, reduce leakage risk, extend the service life of the channel, and optimize the stress state of the channel bottom to improve water conveyance stability.

[0013] In the following description, embodiments of the channel lining pouring construction channel bottom cushion layer reinforcement structure of the present invention will be described with reference to the accompanying drawings.
[0014] Figure 1-5This invention illustrates a channel lining construction and channel bottom cushion reinforcement structure according to an embodiment of the present invention. It includes a concrete foundation 2 installed on top of soil 1. A channel lining 3 is fixedly connected to the top of the concrete foundation 2. Multiple vertical reinforcement bars 4 are provided on the front side of the bottom of the channel lining 3, and multiple vertical reinforcement bars 5 are provided on the rear side of the bottom of the channel lining 3. Both vertical reinforcement bars 4 and 5 are embedded in the inner cavity of the concrete foundation 2. Multiple horizontal stirrups 6 are welded to the surface of the vertical reinforcement bars 4, and multiple horizontal stirrups 7 are welded to the surface of the vertical reinforcement bars 5. Symmetrical to horizontal stirrups 6 and 7, multiple tie bars 8 are welded to the surfaces of the two rear vertical stirrups 4 and the two front vertical stirrups 5. The tie bars 8 are located above horizontal stirrups 6 and 7. As a key component of the reinforcing cage, the tie bars 8 optimize the connection of the reinforcing bars, enhance the force transmission efficiency of local nodes, ensure smooth load transfer, and effectively improve the overall stiffness and stability of the reinforcing cage. During construction, they can suppress rebar displacement and deformation, ensuring precise forming of the reinforcing cage and laying a solid foundation for the overall project quality. Both stirrup 1 (6) and horizontal stirrup 2 (7) have connecting bars 9 fixedly connected to their inner cavities. Reinforcing bars 10 are fixedly connected to the side of the inner cavity of both horizontal stirrup 1 (6) and horizontal stirrup 2 (7) away from the connecting bars 9. Two symmetrical supporting bars 11 are provided in the inner cavities of both horizontal stirrup 1 (6) and horizontal stirrup 2 (7), with their ends fixedly connected to the connecting bars 9 and reinforcing bars 10 respectively. The supporting bars 11 provide support to the inner cavities of horizontal stirrup 1 (6) and horizontal stirrup 2 (7), ensuring that the inner cavities of horizontal stirrup 1 (6) and horizontal stirrup 2 (7) do not expand due to pressure. In the event of deformation, the stability of horizontal stirrup 16 and horizontal stirrup 27 within the concrete foundation 2 is improved. Diagonal bracing 12 is provided at the bottom of the two front support bars 11, and both ends of the two diagonal bracing 12 are fixedly connected to the bottom of vertical bar 4. Diagonal bracing 23 is provided at the bottom of the two rear support bars 11, and the bottom of the two diagonal bracing 23 is fixedly connected to the bottom of vertical bar 25. The tops of vertical bar 14 and vertical bar 25 are fixedly connected to two symmetrical horizontal reinforcing bars 14, which are located within the concrete foundation 2.
[0015] Working Principle: Before construction, the soil at the bottom of the channel (1) is leveled and compacted. Then, vertical reinforcement bars 1-4 and 2-5 are implanted at the top of the soil according to the design position, ensuring the burial depth meets the stress requirements. Next, horizontal stirrups 1-6 are welded to the surface of vertical reinforcement bar 1-4, and horizontal stirrups 2-7 are welded to the surface of vertical reinforcement bar 2-5, forming a symmetrical vertical steel reinforcement skeleton. Simultaneously, connecting bars 9 and reinforcing bars 10 are fixed inside the cavities of horizontal stirrups 1-6 and 2-7, and supporting bars 11 are connected to connecting bars 9 and reinforcing bars 10 to enhance the structural stability of the horizontal stirrups. Finally, diagonal bracing bars 1-12 and 2-5 are installed at the bottom of vertical reinforcement bar 1-4 and the bottom of vertical reinforcement bar 2-5, respectively. The second diagonal bracing bar 13 is installed to further enhance the overall deformation resistance of the steel reinforcement cage. Then, the tie bar 8 is welded to connect the rear vertical bar 4 and the front vertical bar 5. The horizontal reinforcement bar 14 is fixed at the top of the vertical bar 4 and the vertical bar 5 to complete the construction of the overall steel reinforcement cage. After the steel reinforcement cage is completed, concrete is poured to form the concrete foundation 2. The channel lining 3 is poured on top of the concrete foundation 2. At this time, the concrete foundation 2 relies on the internal steel reinforcement cage to provide stable support for the channel bottom cushion layer, preventing the soil 1 from deforming due to water infiltration and erosion. At the same time, it ensures that the channel lining 3 is tightly attached to the concrete foundation 2, and finally realizes the bearing capacity of the channel bottom cushion layer.
[0016] In summary, the channel lining construction and bottom bedding reinforcement structure, through the combined use of vertical reinforcement 4, horizontal stirrup 6, and horizontal stirrup 7, reinforces the inner cavity of the concrete foundation 2. Then, the channel lining 3 is poured on top of the concrete foundation 2. The concrete foundation 2 stabilizes the bottom bedding layer at the bottom of the channel lining 3, thereby enhancing the overall bearing capacity and scour resistance of the bedding layer, preventing seepage and deformation of the original soil foundation, ensuring a tight bond between the lining layer and the bedding layer, extending the service life of the channel, optimizing the stress state of the channel bottom, and improving water conveyance stability.
