[0024] The technical scheme in the embodiments of the utility model will be apparently and completely described below with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative efforts belong to the range of protection of the utility model.

[0025] Embodiment one: please refer to Figure 1 - Figure 6 The utility model provides the following technical scheme: a prefabricated assembly type culvert waterproof structure, including culvert body 1, culvert body 1 one end fixedly connected with the half-enclosing structure's plug-in ring 2, and culvert body 1 is away from the one end of plug-in ring 2 and is equipped with the half-enclosing structure's connecting groove 3, culvert body 1 head-to-tail connection, and culvert body 1 is connected through the interconnection of plug-in ring 2 and connecting groove 3 and forms head-to-tail connection structure, and the top of culvert body 1 is designed as slope structure, and the top of culvert body 1 is equipped with equidistant distribution drainage groove 4, drainage groove 4 extends to the both sides of culvert body 1, and drainage groove 4 forms drainage groove 5 on the both sides of culvert body 1, and drainage groove 5 is equidistantly distributed on the both sides of culvert body 1, and culvert body 1 top fixedly connected with isolation net 6, and isolation net 6 is designed as metal mesh structure, and isolation net 6 is designed as V-shaped structure.

[0026] In the assembly process of culvert waterproof structure, first, multiple culvert bodies 1 are connected head-to-tail through the interconnection of plug-in ring 2 and connecting groove 3. The specific operation is that the half-enclosing structure of plug-in ring 2 is inserted into the corresponding connecting groove 3 of another culvert body 1, so that two culvert units are stably combined into a whole.

[0027] After completing the assembly, the top of each culvert body 1 is designed as slope structure, and V-shaped drainage groove 4 is designed on the top. This structure can better bear external pressure, and the load borne by the top is dispersed to the both sides of the culvert, improving the overall compression resistance of culvert body 1.

[0028] The isolation net 6 effectively isolates the top covering material, avoids direct contact of foreign matters or heavy objects with the covering layer, thereby prolonging the service life of the material. Since the isolation net 6 has a mesh structure, it does not hinder the discharge of water flow, ensures that the water on the top can flow smoothly to the drainage groove 4 and be discharged along the preset path, and the fixation of the isolation net increases the overall structural stability of the top of the culvert, which can maintain the top flat and not deformed even under certain mechanical impact.

[0029] The top of the culvert body 1 is designed as an inclined slope structure. When rainwater or other liquids are retained on the top, the water flow naturally slides along the slope due to gravity, enters the V-shaped drainage groove 4 on the top, and is guided to flow on both sides of the culvert, quickly converges to the drainage grooves 5 on both sides of the culvert body 1 following the slope of the connecting groove, the drainage grooves 5 are equidistantly distributed on both sides of the culvert, which further collect the water flowing out of the connecting groove and discharge the water to the outside, effectively preventing the water from staying on the top of the culvert for a long time.

[0030] In the embodiment two, two sewers 7 are symmetrically arranged on both sides of the bottom of the culvert body 1, the top of each sewer 7 is provided with a mounting groove 8, the inside of the mounting groove 8 is fixedly connected with an isolation plate 9, the inside of the isolation plate 9 is provided with equidistantly distributed openings, the isolation plate 9 completely covers the mounting groove 8, and the inside of each sewer 7 is in communication with the inside of the culvert body 1 through the mounting groove 8 and is in communication with the inside of the drainage groove 4 through the top of the drainage hole 10.

[0031] The two sewers 7 are symmetrically arranged on both sides of the inside of the culvert body 1, the two sewers penetrate through the bottom of the culvert, are responsible for collecting the water flow on the top and the internal water, the sewer 7 is in communication with the inside of the culvert body 1 through the mounting groove 8 on the top, and the inside of the mounting groove 8 is fixedly connected with the isolation plate 9, which prevents impurities from entering the sewer and ensures smooth drainage, the small openings uniformly distributed on the isolation plate 9 allow the water flow to pass freely but block larger particle impurities to avoid the sewer from being blocked, and the drainage hole 10 is arranged on both sides of the culvert body 1, the top of the drainage hole is in communication with the drainage groove 4, and the bottom of the drainage hole is connected with the sewer 7. When the water flow flows along the slope in the top drainage groove 4, it finally flows into the sewer 7 through the drainage hole 10 at the end of both sides.

[0032] After the water enters the sewer, it is further introduced into the underground drainage pipeline line until it is completely discharged from the culvert area, thereby completely solving the problem of water accumulation on the top and inside of the culvert. Through the combination of the slope surface and the V-shaped connecting groove, the water flow is quickly guided into the drainage grooves on both sides of the culvert. The water is further introduced into the sewer 7 through the water guide hole 10, and the filter effect of the isolation plate 9 prevents impurities from entering the drainage channel. The water in the sewer is uniformly discharged into the underground pipe network, and finally discharged to the designated area.

[0033] In the description of the utility model, it is necessary to explain that, unless there is definite stipulation and limitation, the term "connection" "connection" should be understood broadly, for example, it can be fixed connection, also can be detachable connection, or integrally connected, can be mechanical connection, also can be electrical connection, can be directly connected, also can be indirectly connected through intermediate medium. For ordinary skilled in the art, the specific meaning of the above-mentioned terms in the utility model can be understood according to specific circumstances.
