Many debris flow areas exist in West China, direct impact and undercutting by debris flow are the important acting force types for damage to ridges and culverts, and reasonably selecting the structural mode of a passage cross section for a culvert in a debris flow area and making sure that the structural mode can help the roadbed culvert achieve good impact resistance and optimal discharging capacity under the situation of limited terrains are important issues needing to be taken into consideration when a novel culvert in the debris flow area is designed. The invention provides a U-shaped culvert structure with curved bottoming structures. The U-shaped culvert structure comprises a culvert body, the curved bottoming structures, a buffer layer and a culvert inlet. The culvert body comprises a thickened cover plate, trapezoid culvert side plates and culvert foundations. The culvert foundations and the trapezoid culvert side plates are arranged on the two sides of the U-shaped culvert. One curved bottoming structure is arranged at the bottom between the trapezoid culvert side plates on the two sides. The thickened cover plate is arranged on the top between the trapezoid culvert side plates on the two sides. The culvert inlet comprises an inlet conical revetment, an inlet convergence trough and the other curved bottoming structure.

The invention provides a method for producing a health product with a deodorant function, the method is characterized by comprising the following steps: 1) preparing the raw materials; 2) weighting the raw materials; 3) treating the materials; 4) mixing and stirring; 5) adding ghee; 6) granulating. The invention also provides a product with the deodorant function produced by the method. The method is scientific, reasonable and easy for industrialization; the product of the invention takes natural plants as the raw materials, takes the ghee as an adhesive and a sizing agent, the weight of eachpill is 3-5g, the integrated efficacy is enhanced by 3-5 times higher than that of the present products, the onset time is enhanced by 2-3 times, so that the product of the invention is suitable for taking and absorbing by human body and is widely used for enhancing the immunity of the adult and improving the human odor.

The invention relates to the field of stone cutting equipment, in particular to a stone cutting device, which comprises a casing, a cutting mechanism, a motor, a distance measuring sensor and a buzzer alarm. The cutting operation is performed by shielding and enclosing a stone cutting blade and exposing it during operation. , the stone cutting blade can be reset automatically after cutting. The invention solves the technical problem that the blade of the existing hand-held stone cutting device is exposed during use, which is easy to cause damage to the user due to improper operation, and plays the role of protecting the safety of the operator.

The invention provides a surface drainage structure for civil construction engineering. The surface drainage structure comprises a jacket, a grid plate, a screen drum, a mesh guard and a water seal structure, an upper end port of the jacket is matched with the grid plate, a lower end port of the jacket is matched with the water seal structure, the screen drum and the mesh guard are arranged in the jacket, the mesh guard is arranged below the screen drum, the mesh guard is provided with an enclosed cylindrical body, the middle of the side wall of the cylindrical body is recessed inwards, a circular hole is formed in the top of the mesh guard, the upper portion of the screen drum is supported on the inner wall below the upper end port of the jacket, the lower portion of the screen drum penetrates the circular hole in the mesh guard and extends into the mesh guard, and the wall surface of the screen drum outside the mesh guard are provided with screen holes. By the aid of the structure design, the surface drainage structure still can rapidly and smoothly drain after being used for a long time, frequency cleaning sediments in an end port structure is remarkably reduced, and convenience in use is provided.

The invention discloses an anti-drop safety water grate, which comprises an outer frame, two support plates are symmetrically fixed on the inner wall of the outer frame, and the upper ends of the two support plates are mutually offset by a discharge mechanism, and the discharge The mechanism includes two support frames, and the two support frames are jointly connected with a plurality of equidistant beams, and the inner wall of each beam is provided with a telescopic structure, and the telescopic structure includes a slide penetrating through the side wall of the beam. The inner wall of the chute is slidably connected with a closing plate. The advantage is that by setting the closing plate, the water grate can keep the upper end closed when there is no need to discharge a large amount of water flow, which can effectively prevent the items accidentally dropped by pedestrians from falling into the water grate from the gap between the beams, making it impossible or inconvenient to take out It will cause property loss, and at the same time, it can avoid artificially stuffing garbage into the water grate through the gap of the beam, so as to ensure that there is no artificial blockage inside the water grate and maintain effective drainage capacity.
