DETAILED DESCRIPTION

[0023] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Reference Figure 1-Figure 6 As shown, the utility model provides: a farmland water-saving irrigation concrete anti-seepage channel structure, including an anti-seepage channel body 100 and an anti-seepage structure 200, the anti-seepage channel body 100 is cast by concrete, the anti-seepage structure 200 is used to improve the anti-seepage property of the anti-seepage channel body 100, the anti-seepage structure 200 is composed of a first anti-seepage layer 201, a second anti-seepage layer 202 and a third anti-seepage layer 203, the anti-seepage structure 200 is arranged in the anti-seepage channel body 100, when the concrete of the anti-seepage channel body 100 solidifies, the first anti-seepage layer 201, the second anti-seepage layer 202 and the third anti-seepage layer 203 are coated in the anti-seepage channel body 100, the third anti-seepage layer 203 is made of asphalt material, asphalt has good waterproofness and corrosion resistance, can effectively isolate the penetration of groundwater into the channel, and resist the erosion of chemical substances in the soil. In addition, the asphalt layer also has certain elasticity and toughness, which can adapt to the slight deformation of the channel caused by temperature changes or soil movement. When making the anti-seepage channel body 100, concrete is used as the base, the third anti-seepage layer 203 is laid on the concrete, and concrete is poured on the top of the third anti-seepage layer 203. The second anti-seepage layer 202 adopts polyethylene film material, which has excellent anti-seepage performance and chemical stability and is one of the ideal anti-seepage layer materials. When laying the second anti-seepage layer 202, it should be ensured that the polyethylene film material is intact, without holes and cracks. At the same time, attention should also be paid to the bonding treatment between the membrane material and the concrete. Usually, a layer of special adhesive is applied on the surface of the membrane material or other fixing measures are adopted to enhance its bonding strength. The second anti-seepage layer 202 is laid on the concrete on the third anti-seepage layer 203, and concrete is poured on the top of the second anti-seepage layer 202. The first anti-seepage layer 201 adopts composite civil engineering membrane material, which combines the advantages of geomembrane and geotextile, and has both excellent anti-seepage performance and certain tensile strength and elongation. The first anti-seepage layer 201 is laid on the concrete on the second anti-seepage layer 202 , and concrete is poured on top of the first anti-seepage layer 201 .

[0025] In this embodiment, the utility model adopts a multi-layer composite structure, and concrete is filled between multiple anti-seepage layers. After solidification, an anti-seepage channel body 100 is formed. The first anti-seepage layer 201, the second anti-seepage layer 202 and the third anti-seepage layer 203 have good anti-seepage properties, and the material has good corrosion resistance, which can effectively prevent water from penetrating into the ground, thereby playing a role in water saving.

[0026] The cross-section of the anti-seepage channel body 100 is V-shaped, which helps the water flow maintain a faster flow rate and a stable flow state in the channel, reduces the scouring and erosion of the channel bottom by the water flow, and thus improves the durability of the channel. A number of protrusions 101 are evenly arranged on the inside of the anti-seepage channel body 100. When a pedestrian falls into the water channel, he can grab or step on the protrusion 101 to quickly leave the channel, thereby improving the safety of the anti-seepage channel body 100.

[0027] The anti-seepage channel bodies 100 can be spliced ​​together, and the splicing places of multiple anti-seepage channel bodies 100 are filled with asphalt to prevent water leakage. The splicing design of the anti-seepage channel body 100 allows the length of the anti-seepage channel body 100 to be adjusted according to actual needs. Only the prefabricated channel sections need to be spliced ​​one by one to quickly form a complete irrigation channel. The splicing design is conducive to achieving standardized production and reducing production costs. At the same time, since the number of channel sections can be flexibly adjusted according to actual needs, unnecessary waste is avoided, which helps to control the overall project cost.

[0028] A gate assembly 300 is also installed on the anti-seepage channel body 100. The gate assembly 300 includes a support member 301, which is fixed to the anti-seepage channel body 100 by bolts. A groove is vertically opened inside the support member 301, and a gate plate 306 is slidably arranged in the groove in the support member 301. The gate plate 306 moves up and down to control the flow rate and flow rate of water. A toothed disc 303 is movably arranged on the support member 301, and a screw rod 302 is arranged in the toothed disc 303. The outside of the screw rod 302 is provided with an external thread, and the inside of the toothed disc 303 is provided with an internal thread. The screw rod 302 and the toothed disc 303 are movably connected through threads, and the bottom of the screw rod 302 is connected to the top of the gate plate 306. A bevel gear 304 is connected to the support member 301 through a bearing seat and a shaft, and the bevel gear 304 and the toothed disc 303 are meshed with each other, and the shaft on the bevel gear 304 is also connected to a handwheel 305.

[0029] In this embodiment, the hand wheel 305 only needs to be rotated, and the rotation of the hand wheel 305 will drive the bevel gear 304 to rotate, and the bevel gear 304 will then transmit power to the toothed disc 303 through meshing with the toothed disc 303. The up and down movement of the toothed disc 303 will drive the screw rod 302 to move, and the movement of the screw rod 302 will cause the gate plate 306 connected thereto to move up and down. The movement of the gate plate 306 will change the water flow area in the channel, thereby achieving control of the water flow rate and flow rate.

[0030] The anti-seepage channel body 100 is also equipped with a blocking assembly 400, which includes a blocking grid 401. The blocking grid 401 is used to block impurities in the water. A driving wheel 402 and a scraper 403 are provided on the blocking grid 401 through an axial rotation. One side of the scraper 403 is in contact with the outer surface of the blocking grid 401. When water flows, the driving wheel 402 rotates under the action of the water flow, thereby rotating the scraper 403, and the scraper 403 scrapes off the impurities on the blocking grid 401.

[0031] A blocking assembly 400 is installed in the anti-seepage channel body 100. The blocking assembly 400 includes a blocking grid 401. The blocking grid 401 can block garbage in the water. In order to prevent the blocking grid 401 from being blocked by garbage in the water, a driving wheel 402 and a scraper 403 are added to the outside of the blocking grid 401. When the driving wheel 402 rotates under the action of the water flow, the driving wheel 402 causes the scraper 403 to rotate, thereby preventing the blocking grid 401 from being blocked and affecting the flow rate of water.

[0032] Working principle: When in use, the anti-seepage channel body 100 adopts a modular structure. The anti-seepage channel body 100 is installed in the excavated ditch. After multiple anti-seepage channel bodies 100 are spliced, the gaps between the splicing are filled with asphalt. The first anti-seepage layer 201, the second anti-seepage layer 202 and the third anti-seepage layer 203 have good anti-seepage properties, and the material has good corrosion resistance, which can well prevent water from penetrating into the ground, playing a role in water saving. The gate assembly 300 is installed in the anti-seepage channel body 100, and the hand wheel 305 is turned to rotate the bevel gear 304, and the bevel gear 304 makes the toothed disc 303 rotate. 03 rotates, the toothed disc 303 moves the screw rod 302, and then the gate plate 306 moves up and down, so as to control the flow rate and flow velocity of water. A blocking component 400 is installed in the anti-seepage channel body 100. The blocking component 400 includes a blocking grid 401. The blocking grid 401 can block garbage in the water. In order to prevent the blocking grid 401 from being blocked by garbage in the water, a driving wheel 402 and a scraper 403 are added to the outside of the blocking grid 401. When the driving wheel 402 rotates under the action of the water flow, the driving wheel 402 rotates the scraper 403, so as to prevent the blocking grid 401 from being blocked and affecting the flow velocity of water.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
