This utility model discloses a multifunctional artificial field ridge, relating to the field of agricultural facility technology. It includes several main units that interlock along their length. Each main unit has a support leg embedded in the soil at its base, and an arched structure with a downward-facing arc-shaped opening between two legs. Side plates are located on both sides along the length or short side of each main unit. A mulch film fixing clip is attached to the side plate of the main unit, having a slot for fixing the edge of the mulch film. A pre-drilled hole is located on the side plate of the main unit. A pipe fixing clip is also located on the side plate of the main unit, with a buckle inserted into the pre-drilled hole on the side facing the main unit. By integrating multiple functional components such as the mulch film fixing clip, pipe fixing clip, and support fixing block onto the side plate of the main unit, the efficiency of mulch film laying, irrigation pipe installation, and protective facility construction is improved, while significantly reducing on-site construction complexity and the required labor.

This invention relates to a degumming composition, its preparation method, and the degumming method thereof. The degumming composition comprises the following components in weight percentages: 84%–93.5% degumming solvent, 3%–5% solvent oil, 0.5%–3% solid wax, 1%–3% organobentonite, and 2%–5% polar activator; wherein the degumming solvent includes one or more of dichloromethane, N-methylpyrrolidone, and ethylene glycol monobutyl ether. This invention combines the degumming solvent, solid wax, solvent oil, organobentonite, and polar activator in a specific ratio, achieving synergistic effects among the components to obtain a degumming composition with slow evaporation and short degumming time.

The utility model relates to the technical field of tunnel construction, and discloses a temporary support structure for subsurface excavation of a tunnel, which comprises a support column, a chassis, a top column top plate and an attached plate, the chassis is arranged at the bottom end of the support column, and the upper surface of the chassis is fixedly connected with a top pile. According to the temporary supporting structure for the subsurface tunnel, the supporting columns are matched with the bottom holes and the top piles of the chassis in an inserted mode, so that rapid positioning and anti-overturning stability of the foundation structure are achieved; the height of the jacking column is adjusted through threads of the internal thread cylinder, different tunnel section supporting requirements are met, the handle provides a manual screwing operation fulcrum, and the adjusting process is simplified; the top plate and the attached plate form an extensible connecting structure through the first edge groove, the second edge groove and the link block, transverse fine adjustment is allowed, and rock stratum pressure is dispersed. The sliding groove of the attached plate is combined with the clamping block and the thread adjusting assembly of the first supporting rod and the second supporting rod, multi-stage height compensation and settlement adaptation are achieved, and the limiting clamping groove limits the axial stress direction of the supporting rod assembly.
