And the maintenance cost is reduced.

The utility model belongs to the technical field of wetland soil remediation, and particularly relates to a wetland soil remediation protection device which comprises a shell with an open top, a wind-up roller is rotatably arranged in the shell, a protection net is wound on the wind-up roller, when one end of the protection net is pulled, the protection net covers the passing wetland soil, and when the other end of the protection net is pulled, the other end of the protection net is pulled. A protective net is arranged on one side of the shell from outside to inside in a penetrating mode, an opening is further formed in one side of the shell from outside to inside in a penetrating mode, one end of the protective net movably penetrates through the opening from inside to outside, a cutter for cutting the protective net is further arranged above the opening, and a cross beam is transversely arranged on the outer wall of the shell. The protective net is wound in the shell through the winding roller, and when the protective net is pulled outwards, the protective net can conveniently cover the passing wetland soil, so that the wetland soil is protected through the protective net, and the soil is prevented from being scattered along with wind.

The embodiment of the application provides a kind of optical module, it is related to optical communication technical field.Light module includes circuit board, optical assembly and optical fiber.Circuit board has opposite first surface and second surface, and opposite first end and second end;Circuit board is equipped with through hole passing through first surface and second surface;Optical assembly is located in the second surface of circuit board, in the side of through hole opposite from first end;Optical fiber is located on the first surface of circuit board, one end of optical fiber extends out of the first end of circuit board, the other end is arranged in through hole and is coupled to optical assembly;The first surface side of circuit board is equipped with recess, recess is located below optical fiber, and recess extends from the edge of through hole to first end to avoid optical fiber, so that optical fiber is laid more gently, avoid optical fiber and circuit board excessive interference and be damaged by the edge of circuit board.

The application relates to a cable laying drag-reducing roller, which comprises a steel ring and a rolling assembly; the steel ring is sleeved and fixed on the outer surface of a cable, and the inner diameter of the steel ring matches the outer diameter of the cable; the rolling assembly is uniformly installed on the outer surface of the steel ring in the circumferential direction and comprises a support frame and a drum-shaped ball, the support frame is fixed on the steel ring, the drum-shaped ball is installed on the support frame, and the curvature of the generatrix of the drum-shaped ball matches the curvature of the inner wall of a laying pipeline. The application has the advantages that two steel sheets connected through a hinge are buckled on the outer surface of the cable, installation is convenient, the drum-shaped ball is adopted in the rolling assembly, the curvature of the generatrix is the same as the curvature of the pipeline, the contact area of the rolling assembly and the pipeline is increased, the abrasion of the pipeline wall is reduced, and the service life of the drag-reducing roller is effectively prolonged.

The utility model relates to a waterproof coiled material laying tool based on asphalt coating, and relates to the field of waterproof coiled material laying equipment, the waterproof coiled material laying tool comprises oppositely arranged control assemblies, the control assemblies comprise supporting plates, the supporting plates are provided with film covering components, film covering cavities are formed by films on the opposite film covering components and a construction surface, and the film covering components are arranged in the film covering cavities. A film covering part is arranged on the supporting plate, a film covering cavity is formed in the film covering part, an edge pressing part is arranged above the film covering part, the edge pressing part seals the edge of the film covering cavity, a scraper part is arranged above the film covering part, the scraper part abuts against the film covering surface in a sliding mode, and a grouting part is further arranged on the supporting plate. And the grouting component injects a medium into the film covering cavity. The waterproof coiled material laying device has the advantages that the situation of asphalt material overflow caused in the waterproof coiled material laying process is reduced, and stable laying of the waterproof coiled material is achieved.

This utility model proposes an integral inclined laying and fixing structure of composite geomembrane between the dam body and the dam-penetrating structure, belonging to the field of water conservancy engineering technology. It mainly includes a reservoir connecting section culvert structure one, a reservoir connecting section culvert structure two, anchor bolts, nuts, stainless steel pressure plates, neoprene rubber gaskets, and composite geomembrane. The connection between the composite geomembrane on the dam slope and the structure adopts an anchoring + weight connection method. Before laying the membrane, it is ensured that the upstream slope of the dam and the upstream of the outlet structure two are on the same slope. Only two layers of geomembrane are laid at the bottom plate of the outlet structure two. Before laying the membrane, it is ensured that the upstream slope of the dam and the outlet of the outlet culvert are on the same slope. The geomembrane is laid flat, so that the geomembrane is in a stable stress state and avoids tearing and damage.
