[0023] The present utility model will be further described below with reference to the drawings and embodiments.

[0024] Please refer to Figures 1-8 The lap bridge structure for irrigation canals includes: a central beam plate 1 and a rectangular frame sleeve 2 arranged below it. A first positioning plug rod 6 is fixedly installed at the bottom of the rectangular frame sleeve 2 to facilitate its fixation in the canal. An adjusting column 3 is provided inside the rectangular frame sleeve 2. The top of the adjusting column 3 extends above the rectangular frame sleeve 2 and is fixedly connected to the central beam plate 1, and the adjusting column 3 is slidably connected to the top of the rectangular frame sleeve 2. Folding plates 4 are fixedly installed on the outer walls of both sides of the rectangular frame sleeve 2. The same half-threaded screw rod 5 is slidably sleeved on the two folding plates 4, and the half-threaded screw rod 5 is locked with the folding plates 4 through nuts. In addition, in order to facilitate the height adjustment of the central beam plate 1, a plurality of jacks are opened on the adjusting column 3. The half-threaded screw rod 5 penetrates through the uppermost jack and is slidably connected to its inner wall. In the later stage, only by adjusting the half-threaded screw rod 5 to insert into jacks at different heights can the height of the central beam plate 1 be adjusted. Secondary beam plates 7 are provided on both sides of the central beam plate 1, and first horizontal slots 8 are opened on both sides of the central beam plate 1. Plug plates 9 are provided in the two first horizontal slots 8. One side of the two plug plates 9 away from each other is fixedly connected to the two secondary beam plates 7 respectively. Second horizontal slots 20 are opened on one side of the two secondary beam plates 7 away from each other. The second horizontal slots 20 are adapted to the plug plates 9, and the second horizontal slots 20 can enable the splicing operation between adjacent two secondary beam plates 7. Positioning grooves 10 are opened at the bottoms of the two plug plates 9, and concave frames 17 are fixedly installed at the bottoms of the two secondary beam plates 7. Linking plates 15 are provided in the two concave frames 17. Top springs 19 are fixedly installed at the bottoms of the two linking plates 15. The bottom ends of the two top springs 19 are fixedly connected to the inner walls of the bottoms of the two concave frames 17 respectively. Positioning columns 16 are fixedly installed at the tops of the two linking plates 15. The top ends of the two positioning columns 16 extend into the two positioning grooves 10 respectively, and the positioning columns 16 are slidably connected to the bottom of the central beam plate 1. In this way, a fixation is formed between the secondary beam plate 7 and the central beam plate 1, and at the same time, the adjacent two secondary beam plates 7 can also be fixed.

[0025] In addition, guiding columns 18 are fixedly installed at the bottoms of the two linking plates 15. The bottom ends of the two guiding columns 18 extend below the two concave frames 17 and are slidably connected to the corresponding concave frames 17, and the two guiding columns 18 respectively penetrate through the two top springs 19. In this way, a continuous top force can be provided for the positioning column 16 to tightly clamp it in the positioning groove 10.

[0026] In the above method, in order to conveniently take out the clamping column 16 from the clamping groove 10 in the later stage, flat grooves 11 are provided at the tops of the two auxiliary beam plates 7. Sunk grooves 12 are provided on the inner walls of the bottoms of the two flat grooves 11. Sealing plates 13 are fixedly installed in the two flat grooves 11 through screws. Pressing rods 14 are provided in the two sunk grooves 12. The pressing rods 14 are rectangular, so that the connecting plates 15 will rotate. The bottom ends of the two pressing rods 14 respectively extend below the two auxiliary beam plates 7 and are fixedly connected to the corresponding connecting plates 15. The pressing rods 14 are slidably connected to the bottoms of the auxiliary beam plates 7.

[0027] In this method, in order to enable the auxiliary beam plates 7 to adapt to the height of the central beam plate 1, threaded columns 22 are fixedly installed at the bottoms of the two auxiliary beam plates 7. Threaded sleeves 21 are sleeved on the two threaded columns 22 in a threaded manner. Second positioning insertion rods 23 are fixedly installed at the bottoms of the two threaded sleeves 21.

[0028] The working principle of the lap bridge structure for the irrigation canal provided by the present utility model is as follows:

[0029] Before laying the lap bridge, prepare the corresponding number of auxiliary beam plates 7;

[0030] When a lap bridge needs to be set on the irrigation canal, first place the central beam plate 1 in the middle position of the canal, then insert the first positioning insertion rod 6 into the bottom of the canal. Subsequently, turn the nut on the half-threaded screw rod 5 and pull it out of the adjusting column 3. At this time, the adjusting column 3 has no external object to hold and limit it. Then lift the central beam plate 1 upward until the bottom end face of the central beam plate 1 is flush with the top end of the canal. Then slightly adjust the insertion depth of the first positioning insertion rod 6 to align the corresponding jack with the half-threaded screw rod 5. Subsequently, fix the half-threaded screw rod 5 on the two folding plates 4 again. At this time, the positioning of the central beam plate 1 is completed;

[0031] Then take out an auxiliary beam plate 7. First, remove the sealing plate 13 on it, then press down the pressing rod 14 to bring the clamping column 16 to the lowest position. At this time, the top spring 19 is in a compressed state. Subsequently, insert the insertion plate 9 on it into the first horizontal slot 8 on one side of the central beam plate 1, and then release the pressing rod 14. The compressed top spring 19 releases elastic force and directly brings the clamping column 16 into the clamping groove 10, thus completing the installation between the auxiliary beam plate 7 and the central beam plate 1. Subsequently, rotate the threaded sleeve 21 and insert the second positioning insertion rod 23 into the bottom of the canal as well;

[0032] After that, take out the next auxiliary beam plate 7 and install it on the other side of the central beam plate 1 with the same operation as above. Immediately afterwards, take out the next auxiliary beam plate 7 and install it on the previous auxiliary beam plate 7 with the same operation as above. At this time, the insertion plates 9 on the remaining auxiliary beam plates 7 are all inserted into the second horizontal slots 20 on the previous auxiliary beam plate 7;

[0033] As each auxiliary beam slab 7 is installed, the entire bridge is gradually completed. After the two outermost auxiliary beam slabs 7 on the left and right come into contact with the tops on both sides of the water channel, the bridging work of the bridge is completed and it can be put into use.

[0034] When the entire bridge needs to be demolished later, start from the outermost auxiliary beam slab 7 on one side, remove the sealing plate 13 on it, then hold down the pressure rod 14 and pull out the positioning column 16 from the positioning groove 10, so as to separate the two auxiliary beam slabs 7. After that, remove the auxiliary beam slabs 7 in sequence according to the above method.

[0035] Compared with the related technology, the bridging structure for irrigation water channels provided by the present utility model has the following beneficial effects:

[0036] The present utility model provides a bridging structure for irrigation water channels. By separately setting the central beam slab 1 and the auxiliary beam slab 7, during the actual laying process of the bridge, the corresponding number of auxiliary beam slabs 7 can be selected according to the actual width of the water channel, with high flexibility and wide application range. It can be reused after demolition later. Moreover, the individually set central beam slab 1 and auxiliary beam slab 7 are small in volume, convenient for people to carry, and to a certain extent improve the convenience.

[0037] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly.
