Description

Technical Field

[0001] The utility model belongs to the technical field of farmland water conservancy projects, and in particular relates to a farmland water conservancy water diversion channel structure. Background Art

[0002] Traditional water diversion channels are mostly ditches dug directly on the land. Permanent and semi-permanent water diversion channels that need to be used for a long time will be rammed to increase their strength. Since these traditional water diversion channels are dug directly on the soil, even if they are rammed, they cannot prevent a large amount of irrigation water from seeping into the ground during the transportation process. The utilization rate of irrigation water is not high when the water diversion distance is long.

[0003] In order to solve the problem of water waste due to seepage, the current methods of manufacturing water diversion channels by on-site molding or reinforcing the inner surface of rammed water diversion channels are mostly used. When the water diversion channel is manufactured by on-site molding, the entire water diversion channel is a whole, which is easy to crack in areas with large seasonal temperature differences, resulting in water seepage. At the same time, it is not convenient to dismantle and cannot be reassembled after dismantling, and cannot be used for semi-permanent water diversion channels. In addition to the above-mentioned disadvantages of the on-site molding method, the method of reinforcing the inner surface of the rammed water diversion channel has the problem that the cement layer is thin and fragile. When the rammed layer is dispersed by a small amount of water flow, the cement layer will be shattered over a large area, losing its anti-seepage and water-saving functions.

[0004] After searching, it is found that there are many forms of prefabricated water channels in the prior art, such as a prefabricated channel based on a mortise and tenon structure disclosed in the patent with the authorization announcement number CN216999564U, which includes a number of spliced ​​U-shaped channel units, the upper and lower notches of adjacent U-shaped channel units are spliced ​​together, and a prefabricated sealing ring is placed between the upper notch and the lower notch. The above-mentioned prefabricated water channel improves the construction efficiency and reduces the labor intensity, but it still has the following problems: First, the sealing ring is only pressed together by the self-weight of the upper notch and the lower notch, and it is only spliced, the sealing effect is limited, and it is easy to cause seepage and leakage; in addition, once the foundation settles, the adjacent splicing parts are prone to deformation and leakage due to the lack of a fixed connection method, and this connection method has limited ability to resist uneven deformation of the foundation. Second, the structure is not convenient for installing the water-stop baffle at the end, and there are certain limitations in use.

[0005] In view of this technical problem, it is necessary to improve the existing water diversion channel structure. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0036] Embodiment 1:

[0037] like Figure 1 - Figure 8 As shown, in response to the first technical problem recorded in the background technology, this embodiment proposes a farmland water conservancy water diversion channel structure, including a channel body, the channel body includes a plurality of channel units 1 spliced ​​together, the cross-sectional shape of the channel unit 1 is a U-shaped or trapezoidal structure; a pressure top 11 is provided on the top of the channel unit 1, and locking holes 111 are respectively opened at the head and tail ends of the pressure top 11; a sealing gasket 4 is provided between adjacent channel units 1; adjacent locking holes 111 between adjacent channel units 1 are matched with tie pieces 3, and adjacent channel units 1 are tied and fixedly connected as a whole by the tie pieces 3 to form a long-distance water supply channel.

[0038] The following is a further introduction to the above components:

[0039] In this embodiment, the anchor 3 includes a cross bar 31, and the two ends of the cross bar 31 are vertically connected to the vertical bars 32. The cross bar 31 and the vertical bars 32 form a U-shaped structure. The vertical bars 32 can be formed by bending the cross bar 31, and the cross bar 31 and the vertical bars 32 are made of the same material; the outer wall of the vertical bar 32 is provided with a threaded section; the outer wall of the vertical bar 32 is also fixed with an inclined block 33, and the inclined surface has an inclined surface, the small end of the inclined block 33 is at the bottom, and the large end is at the top; the two inclined blocks 33 are symmetrically arranged; the vertical bar 32 and the inclined block 33 can be inserted in the locking hole 111; the shape of the locking hole 111 must be compatible with the shape of the vertical bar 32 and the inclined block 33; for example, in this embodiment, the vertical bar 32 adopts a cylindrical structure, so the locking hole 111 is a circular + rectangular mouth style, which can be referred to Figure 2 or Figure 3 .

[0040] The anchor 3 also includes a sleeve 34, a wall of which is provided with a slot 341, the vertical rod 32 is sleeved in the sleeve 34 and the inclined block 33 can move relatively along the slot 341; when in use, the top end of the sleeve 34 is supported on the bottom of the pressure top 11; the vertical rod 32 is threadedly connected with a fastening nut 35; when the fastening nut 35 is screwed, the fastening nut 35 squeezes the sleeve 34, and the inclined block 33 moves downward to pull the adjacent channel units 1 together.

[0041] Installation method of anchor 3:

[0042] After the adjacent channel units 1 are spliced, the two vertical rods 32 of the anchor 3 are respectively inserted into the adjacent locking holes 111 of the adjacent channel units 1, and the bevel block 33 is also inserted into the locking hole 111 along with the vertical rod 32; then the sleeve 34 is sleeved on the vertical rod 32, and the bevel block 33 moves relatively along the groove 341 of the sleeve 34; then the fastening nut 35 is screwed, the fastening nut 35 squeezes the sleeve 34, and the bevel block 33 moves downward to pull the adjacent channel units 1 tightly together.

[0043] In this embodiment, considering that the channel unit 1 is only provided with an anchor 3 at the top, and lacks an anchor near the bottom, this may cause uneven force and affect the sealing effect of the sealing gasket 4. In this regard, further improvements are made:

[0044] The channel unit 1 is fixedly connected with ribs 101 on the outer wall at both ends, and four ribs 101 are correspondingly arranged on the outer wall of each section of the channel unit 1. The adjacent ribs 101 between adjacent channel units 1 are connected and fixed by first bolts 2; the ribs 101 are arranged at a position close to the bottom of the channel unit 1; the ribs 101 are provided with through holes 1011. When in use, the first bolt 2 is passed through the through hole 1011, and then the first nut is tightened to achieve the approach of the two ribs 101, and then the adjacent channel units 1 are pulled tightly together. Combined with the anchor 3 on the top, the overall interlocking effect is very good, the sealing effect is good, it is not easy to loosen, and it is not easy to leak.

[0045] It should be noted that both ends of the channel unit 1 are provided with an engagement groove 103, and a sealing gasket 4 is detachably inserted and connected at the engagement groove 103. In this embodiment, the sealing gasket 4 includes a rubber strip 41, and flanges 42 are respectively connected to both sides of the rubber strip 41, and the rubber strip and the flange 42 are integrally molded; the flange 42 can be inserted into the engagement groove 103, and the rubber strip 41 is attached to the outer wall of the end of the channel unit 1.
