The application discloses a kind of super-hydrophobic soil water-resisting layer and its construction method, belong to slope protection engineering technical field, the super-hydrophobic soil water-resisting layer is used for soft rock slope, by quality ratio is composed of basic component and functional component, basic component includes polymer curing agent 20 parts, guest soil 60 parts, straw fiber 5 parts;Functional component includes the total quality 0.5% of basic component starch graft acrylamide type microbial water-retaining agent, 2 parts nano SiO2, 0.3 parts KH-550 silane coupling agent, it can also be mixed with specific ratio grass seed.Its construction method includes four core steps of slope pretreatment, bottom curing, water-resisting layer laying, later maintenance, and drainage blind ditch strengthening measures are added for strong weathered soft rock slope.The super-hydrophobic soil water-resisting layer realizes the ecological restoration and long-acting water-resisting protection of soft rock slope, is suitable for the protection of various soft rock slopes in highway, railway, water conservancy and other engineering, has significant technical innovation and engineering application value.

The present invention provides a soft multi-layer plastic hose and a preparation method and application thereof, belonging to the technical field of plastic hoses. The present invention mixes thermoplastic polyolefin and high-density polyethylene in a mass ratio of 70:30, and extrude the mixture in a multi-layer co-extruder as the outer layer of the soft multi-layer plastic hose. The processing temperature of the outer layer is 180-200°C. Under a fixed ratio and temperature, the thermoplastic polyolefin and high-density polyethylene in the present invention have the best compatibility. The outer layer material prepared after blending has low gloss, low surface granularity, and is comfortable to touch, which is more suitable for the packaging requirements of high-end products.

The waterproof anti-deformation carton comprises a carton body, notches are formed in the four corners of the carton body in a penetrating mode, reinforcing pieces used for reinforcing the carton body are slidably connected to the inner surfaces of the notches, sliding grooves are formed in the outer surface of the carton body, and fixing pieces used for fixing the reinforcing pieces are slidably connected to the inner surfaces of the sliding grooves. Protection parts are arranged in the box body in a layered mode. Through cooperative use of the reinforcing pieces and the fixing pieces, the four corners of the box body are changed into two 180 degrees and two zero degrees respectively, so that the folding effect of the box body is achieved, and during transportation, the occupied space is reduced, and the transportation efficiency is improved.
