Description

Technical Field

[0001] This invention relates to the field of ski slopes in snow parks, and more particularly to an anti-slip structure for indoor ski slopes and its construction method. Background Technology

[0002] The construction of the base layer for indoor ski slopes is quite complex. It mainly consists of various structural and bonding materials, including pre-embedded anti-condensation heating pipes, a waterproof layer, an insulation layer, a cement mortar protective layer, and a concrete layer. Because the base layer generates significant sliding forces, and due to the initial stages of snowmaking and the annual temperature variations outdoors, substantial deformation occurs between the main structure's floor and the base layer. Under the influence of these sliding forces, the various structural layers of the base layer can slip and fail. Summary of the Invention

[0003] The purpose of this invention is to solve the problem of slippage and damage to the various structural layers of the base layer under the action of ski slope sliding force.

The second C20 fine aggregate concrete contains... 4@250 steel wire mesh; Step 8, Secondary Waterproofing: Adhere a 4mm thick bridge-specific SBS modified bitumen waterproof membrane (polyester-based type II) to the top of the second C20 fine aggregate concrete. Step 9, Cold Coil Layer Installation: Install a cold coil layer on top of the waterproof membrane and pour a 120mm thick C30 antifreeze concrete. Step 10, Snow layer setup: Lay a 400mm thick snow layer on top of the cold coil layer.

[0006] Optionally, in step one, the cleaning of the waterproof reinforced concrete base slab must ensure that there are no stones or loose soil, so as to provide a working surface for the next layer of waterproofing and to implant anti-slip elements. 10 steel bars are used to resist the slippage force between the hot coil layer and the structural base plate.

[0007] Optionally, in step two, two coats of polyurethane waterproof coating are applied to a thickness of 1.5mm, and the implanted... Special attention should be paid to the location of the 10 rebars.

[0008] Optionally, in step three, the reinforcing mesh is... 6. Steel mesh, the heating coil is fixed to the steel mesh, and a 60mm thick first C20 fine stone concrete is poured.

[0009] Optionally, in step four, after the first C20 fine aggregate concrete has solidified, the top of the first C20 fine aggregate concrete should be cleaned before laying a rough-surface vapor barrier membrane.

[0010] Optionally, in step five, the three 50mm thick B1 grade XPS extruded polystyrene boards laid on top of the textured vapor barrier membrane are laid with staggered joints, and each layer is fully coated with special adhesive to ensure that there are no gaps between each layer of XPS extruded polystyrene boards.

It effectively solves the slippage damage caused by the sliding force of the ski slope to the various structural layers of the base. Moreover, the anti-slip structure is simple and easy to install, and will not increase the construction cost, bringing significant anti-slip capability at a low construction cost.
