[0005] The above technical purpose of the utility model is realized by the following technical scheme: a prefabricated drainage ditch comprises a plurality of splicing sections, a slot is formed in the top surface of the splicing section and penetrates both ends of the splicing section, a baffle is slidably connected to the inner side wall of the slot, the baffle cuts off the slot, a through slot is formed in the top end of the baffle, and the through slot penetrates the baffle along the length direction of the splicing section.

[0006] The utility model is further provided with a straight slot formed in the baffle, the straight slot is vertically arranged, the straight slot penetrates the baffle along the length direction of the splicing section, and the width of the straight slot is smaller than that of the through slot.

[0007] The utility model is further provided with a linear array of the straight slots along the width direction of the splicing section.

[0008] The utility model is further provided with an anti-blocking block fixedly connected to the bottom surface of the splicing section, and one side of the anti-blocking block is attached to one side of the baffle.

[0009] The utility model is further provided with an inclined surface formed on the side of the anti-blocking block away from the baffle, and the cross section of the anti-blocking block is in the shape of a right-angled trapezoid with the upper part being smaller and the lower part being larger.

[0010] The utility model is further provided with the two side walls of the slot being embedded with the two sides of the baffle respectively.

[0011] In summary, the utility model has the following beneficial effects: by making sundries disperse in each splicing section instead of concentrating at downstream, reduce the possibility of single splicing section blockage, ensure the drainage effect of drainage ditch, reduce the maintenance and cleaning frequency of drainage ditch, the straight groove reduces the minimum water level that water flow needs to reach through the baffle, avoid the water level being too low to cause sundries to deposit between two baffles, the width of straight groove is small, still block most sundries, and multiple straight grooves increase the flow area on the baffle.

[0015] The utility model will be described in detail below in combination with the drawings and examples.

[0016] Example: a prefabricated drainage ditch, as shown in Figure 1 , Figure 2 , including several splicing sections 1, the top surface of splicing section 1 is provided with the slot 2 that passes through both ends of splicing section 1, the inner side wall of slot 2 is slidably connected with baffle 3, baffle 3 cuts off slot 2, the top end of baffle 3 is provided with through groove 4, through groove 4 penetrates baffle 3 along the length direction of splicing section 1, and both sides of baffle 3 are embedded in the two side walls of slot 2.

[0017] Specifically, splicing section 1 is formed by pouring concrete, in the embodiment, in order to facilitate demonstration, the number of splicing section 1 is three, the slot 2 on adjacent splicing section 1 is communicated as water flow channel, two sliding grooves are formed on the two side walls of slot 2 respectively, baffle 3 is embedded in the sliding groove in the process of descending, so as to ensure the connecting strength between baffle 3 and splicing section 1, through groove 4 is located at the top end of baffle 3, but through groove 4 does not penetrate the top surface of baffle 3, forms a handle structure at the bottom end of baffle 3, facilitates people to pull baffle 3, when sundries move along with water flow, part of sundries is blocked by baffle 3 and descends in the corresponding splicing section 1, and water flow continues to flow from through groove 4 to the next splicing section 1, by making sundries disperse in each splicing section 1 instead of concentrating at downstream, reduce the possibility of single splicing section 1 blockage, ensure the drainage effect of drainage ditch, reduce the maintenance and cleaning frequency of drainage ditch.
