[0032] In this embodiment, a limiting slot 104 with a circular groove structure is provided at the top surface of the splicing body 1 adjacent to the four edge angles; a limiting plug 203 matching the structural size of the limiting slot 104 is fixedly installed at the bottom surface of the closed cover block 2 adjacent to the four edge angles; when the bottom surface of the closed cover block 2 is in contact with the top surface of the splicing body 1, the four limiting plugs 203 are respectively limited and inserted into the four limiting slots 104; the front and rear surfaces of the closed cover block 2 are provided with A grip groove 201; the left end face of the splicing main body 1 is symmetrical front to back and is provided with two splicing slots 102 with isosceles trapezoidal groove structures, and the splicing slots 102 pass through the top surface of the splicing main body 1; the right end face of the splicing main body 1 is symmetrical front to back and is fixedly connected with two splicing plug-ins 103 whose structural dimensions match the splicing slots 102; when two adjacent splicing main bodies 1 are spliced ​​and installed, the splicing plug-in block 103 of one splicing main body 1 is limitedly inserted into the splicing slot 102 of the other splicing main body 1.

[0033] The working principle of this embodiment:

[0034] During water conservancy construction, a corresponding number of splicing bodies 1 can be selected and spliced ​​together according to the length of the irrigation area to form an irrigation channel. The specific operation is as follows:

[0035] When two adjacent splicing bodies 1 are spliced ​​and installed, the splicing plug block 103 of one splicing body 1 is aligned with the splicing slot 102 of the other splicing body 1 and inserted to a limited position, thereby realizing the splicing and installation operation of the two adjacent splicing bodies 1, and the spliced ​​and installed drainage grooves 101 form an irrigation channel for water flow transportation;

[0036] In daily use, in order to prevent foreign debris from falling into the drainage trough 101 and causing obstruction of water flow and to prevent pedestrians from accidentally stepping into the drainage trough 101, the top open end of the drainage trough 101 is closed by closing the cover block 2. The specific operation is as follows:

[0037] The hand grasps the lifting groove 201 to realize the lifting and lowering operation of the closed cover block 2, and the limiting plug 203 is aligned with the limiting slot 104 and inserted. At this time, the closed cover block 2 covers the top surface of the splicing body 1, and the matching plug 202 is limitedly inserted in the top area inside the drainage groove 101; through the limited insertion and cooperation between the limiting plug 203 and the limiting slot 104, the front and back and left and right movements of the closed cover block 2 are limited;

[0038] In order to prevent others from moving the closed cover block 2 and affecting the closing of the top open end of the drain groove 101, after the closed cover block 2 covers the top surface of the splicing body 1, an inner hexagonal wrench matching the structural size of the twisting groove 301 can be inserted into the twisting groove 301 and rotated, thereby driving the limit blocking block 302 to rotate along the rotating groove 205, so that the truncated surface 303 no longer corresponds to the position of the open end of the rotating groove 205, and at this time, the limit blocking block 302 protruding from the open end of the rotating groove 205 is limitedly inserted in the limit blocking groove 105, and the limit blocking groove 105 and the limit blocking block 302 are limited by the limit plug-in cooperation, so that the up and down movement of the closed cover block 2 is limited;

[0039] Based on the above-mentioned limit for the front-back, left-right and up-down movement of the closing cover block 2, the closing cover block 2 cannot be moved before the two limit blocking blocks 302 are released from the limit blocking groove 105, so as to ensure that the closing of the top open end of the drainage groove 101 by the closing cover block 2 is not affected;

[0040] When it is necessary to release the limit of the up and down movement of the closed cover block 2, the truncated surfaces 303 of the two limit blocking blocks 302 need to be correctly rotated to the corresponding open end positions of the rotation grooves 205 at the same time, so that the limit blocking blocks 302 can be separated from the limit blocking grooves 105 to release the limit of the up and down movement of the closed cover block 2. However, since the truncated surfaces 303 of the limit blocking blocks 302 are in a blocked state, they cannot be observed. Therefore, this design can effectively prevent others from releasing the limit of the up and down movement of the closed cover block 2.

[0041] When the closed cover block 2 needs to be disassembled, since the two inner end side surfaces corresponding to the two directions of the truncated surfaces 303 in the twisting groove 301 both adopt an inclined surface structure with the bottom inclined inward, it is only necessary to touch and determine which part of the twisting groove 301 is the inclined end surface to know the position of the truncated surface 303, and then cooperate to rotate the inclined end surface of the corresponding truncated surface 303 to the direction of the limiting blocking groove 105, so that the truncation surface 303 of the limiting blocking block 302 can be correctly rotated to the corresponding opening end position of the rotating groove 205, thereby realizing the separation of the limiting blocking block 302 and the limiting blocking groove 105, and releasing the upper and lower movement limit of the closed cover block 2. At this time, the separation operation of the closed cover block 2 and the splicing body 1 can be realized by grasping the lifting groove 201.
