Through transmission between the gear and rack, when the crossbar is in the lower position within the beam, it begins to move upwards. Concrete mortar is then transported through the delivery pipe to the upper curved cavity of the hopper. The flat-laying auger shaft evenly distributes the concrete mortar in the hopper laterally, applying it to the inner wall of the culvert via the lower flat plate of the hopper. Under the elastic energy storage of the torsion spring, the plate flattens and smooths the concrete mortar on the inner wall of the culvert. When the crossbar is in the higher position within the beam, it... concrete delivery mortarWith the pump in a non-operating state, the drive motor of the flat-laying screw shaft is also in a non-operating state, as is the power motor. This causes the brake screw to rotate in the opposite direction on the inner block, and the inner end of the brake screw acts on the beam, thereby completing the coating construction work on one area of ​​the vertical inner wall of the culvert.

[0049] The technical advantages of the above solutions are: they enable the construction of inner and outer coating layers for culvert inner walls, and the use of forklifts as the moving medium improves the construction efficiency of culvert inner wall coating.

The design of technical features such as beams, receiving grooves, insertion holes, horizontal bars, inner blocks, first vertical bars, second vertical bars, rods, and plates conforms to the Patent Law and its implementing regulations.

[0051] In this technical solution, the key technical feature is the prefabrication of an intermediate medium layer on the inner wall of the culvert, which acts on the raw material of the inner wall coating. This is the main body of the culvert inner wall coating construction device, the mesh, and the nozzle. In the technical field of culvert inner wall coating construction device and method based on rainwater and sewage diversion, this solution is novel, inventive, and practical.

[0103] In verifying this invention, the inventors abandoned the existing technical features of applying concrete mortar to the inner wall of the culvert before smoothing, which, due to the high internal humidity of the culvert, affected the setting of the concrete mortar and its adhesion to the culvert inner wall. Instead, they proposed a technical feature of prefabricating an intermediate medium layer on the inner wall of the culvert to act on the coating material. This resulted in the first unexpected technical effect: the substrate for attaching the outer coating of the culvert inner wall was changed, using a convex-concave surface instead of a flat surface. The second unexpected technical effect was the elimination of the environmental influences on the inner wall of the culvert. The third unexpected technical effect was the use of a forklift as a construction tool, which met the requirements of the construction site.

This realizes the prefabrication of the intermediate medium layer that acts on the raw materials of the culvert inner wall coating on the culvert inner wall. This solves the technical problem that when concrete mortar is applied to the culvert inner wall before smoothing, the high internal humidity of the culvert inner wall affects the solidification of the concrete mortar and its adhesion to the culvert inner wall. Therefore, the construction effect of the culvert inner wall coating is improved.

[0114] 2. By designing beam 1, rack 2, gear 3, power motor 4, crawler frame 5, brake screw 6, conveying pipe 7, bin 8, flat auger shaft 9, flat plate 91, and torsion spring 92, concrete mortar coating operation on the inner wall of the culvert can be realized.

[0115] 3. Due to the design of sliding rod 94, guide roller 95, external frame 90 and winding drum 96, the wire mesh 93 can be laid and wound on the beam 1.

[0116] 4. Due to the design of the movable seat 97 and the winch 99, the lifting and lowering motion of the nozzle 98 on the screen 93 is realized.

[0117] 5. Because the design limits the numerical range of the structural shape, the numerical range is a technical feature in the technical solution of this invention, and is not a technical feature obtained by formula calculation or a limited number of experiments. The experiment shows that the technical feature of the numerical range has achieved very good technical effect.

[0118] 6. Due to the design of the technical features of this invention, and the combined effect of the individual and collective technical features, experiments have shown that the performance indicators of this invention are at least 1.7 times that of existing performance indicators, and the invention has been evaluated to have good market value.

[0119] Other technical features that connect the culvert inner wall coating construction device body, mesh 93, and nozzle 98 to the intermediate medium layer prefabricated on the inner wall of the culvert to act on the raw material of the culvert inner wall coating are also embodiments of the present invention.
