[0037] To this end, the following solutions are proposed:

[0038] See also Figure 1 The present invention provides a ski slope anti-slip ramp structure. The cross-section of the ski slope anti-slip ramp structure comprises, from the inside out, a structural layer 100, a functional layer 200, and a snow layer 300. The structural layer 100 is made of reinforced concrete and forms a ramp with steps on the upper surface of the ramp. The functional layer 200 is disposed outside the structural layer 100 and is located on the upper surface of the ramp of the structural layer 100. The snow layer 300 covers the functional layer 200.

[0039] In the anti-slip ramp structure of the ski slope provided by the present invention, in some embodiments, the structural layer 100 is a cast-in-place, assembled or assembled integral waterproof reinforced concrete floor slab. For example, a cast-in-place waterproof reinforced concrete floor slab is used to form a slope greater than 10°, and the surface is set in a stepped shape along the slope requirements, and the water-resistance grade can reach P8.

[0040] like Figure 1As shown, in the ski slope anti-sliding slope structure provided by the utility model, the cross section of each step of the functional layer 200 comprises from inside to outside: a first waterproof layer 201, a hot branch pipe layer 202, a steam isolation layer 203, an insulation layer 204, an isolation layer 205, a second waterproof layer 206 and a cold branch pipe layer 207.

[0041] Specifically, in the functional layer 200 of the ski slope anti-sliding slope structure of the utility model, the first waterproof layer 201 is a polymer waterproof coating, further, a polymer cement elastic waterproof coating with a thickness not less than 2.0mm or a penetration crystalline waterproof coating with a thickness not less than 1.0mm, a dosage not less than 1.5kg / m 2 The construction mode is brushing type, and the waterproof layer 201 is brushed on the entire surface of the step ladder shape of the structural layer 100.

[0042] The polymer cement elastic waterproof coating of the utility model is generally an organic liquid material composed of polymer emulsion such as acrylate emulsion and ethylene-vinyl acetate copolymer emulsion and various additives, and an inorganic powder material composed of cement, quartz sand, calcium carbonate and water reducing agent and other additives, which is a two-component water-based building waterproof coating formed by a certain proportioning, and has rigidity of inorganic powder material and flexibility of organic liquid material.

[0043] The penetration crystalline waterproof coating of the utility model is generally a rigid waterproof coating made of Portland cement or ordinary Portland cement and refined quartz sand (silica sand) as a base material and mixed with special active chemicals, which utilizes the special chemical active substances contained in the waterproof coating to penetrate into the concrete under the action of carrier water, reacts with unhydrated cement particles or free calcium hydroxide, calcium oxide and other alkaline substances in the concrete to generate insoluble needle-shaped crystals, which block the capillary pores and micro-cracks in the concrete, making the concrete dense, thereby enhancing the impermeability of the concrete.

[0044] According to the national standard GB18445-2001, waterproof coatings are divided into I type waterproof coatings and II type waterproof coatings, and compared with I type waterproof coatings, II type waterproof coatings have higher impermeability, and the polymer cement elastic waterproof coating or the penetration crystalline waterproof coating of the utility model both need to meet the standard of II type waterproof coatings.

[0045] Furthermore, in the functional layer 200 of the anti-slip ramp structure of the ski slope of the present invention, a heat branch pipe layer 202 is arranged on the outside of the first waterproof layer 201 and on the horizontal plane forming a stepped shape. The heat branch pipe layer 202 is composed of C20 fine stone concrete material with a thickness of 50-70 mm (in the field of building concrete, it is well known that the standard value of compressive strength of C20 concrete is 20 MPa, and the standard value of slump is 180 mm; the standard value of compressive strength of C30 concrete is 30 MPa, and the standard value of slump is 150 mm).

In one embodiment, the vapor barrier layer 203 can be a textured vapor barrier film.

[0047] Furthermore, in the functional layer 200 of the ski slope anti-slip ramp structure of the present invention, an insulation layer 204 is provided outside the vapor barrier layer 203. This insulation layer 204 is made of three layers of B1-grade polystyrene foam (XPS) insulation boards with a total thickness of 120-180 mm, staggered and overlapped to form a stepped shape. XPS insulation boards are rigid boards made from polystyrene resin with flame retardants added through a specialized process for continuous extrusion and foaming. They have a dense, closed-cell honeycomb structure, characterized by low thermal conductivity, low water absorption, and high compressive strength.

[0048] Furthermore, in the functional layer 200 of the anti-slip ramp structure of the ski slope of the present invention, an isolation layer 205 is arranged on the outside of the insulation layer 204 and on the horizontal surface forming a stepped shape.

The construction method can be cast-in-place or prefabricated assembly.

[0049] Furthermore, in the functional layer 200 of the anti-slip ramp structure of the ski slope of the present invention, a second waterproof layer 206 is arranged on the outer side of the isolation layer 205 and on the entire surface forming a stepped shape. The second waterproof layer 206 is a layer of styrene-butadiene-styrene (SBS) modified asphalt waterproof membrane, preferably a layer of long sheet-like rollable waterproof membrane with a thickness of not less than 4 mm, with polyester felt as the base, styrene-butadiene-styrene (SBS) copolymer thermoplastic elastomer modified asphalt as the coating material, and polyethylene film, fine sand or mineral aggregates on both sides. It has good high and low temperature resistance and excellent waterproof performance, high hydrophobicity, adhesion, elongation, aging resistance and corrosion resistance, and the construction method is laying.

[0050] Furthermore, in the functional layer 200 of the anti-slip ramp structure of the ski slope of the present invention, a cold branch pipe layer 207 is arranged on the outside of the second waterproof layer 206. The cold branch pipe layer 207 is made of C30 antifreeze concrete material with a thickness of 100-140mm. Two layers of steel mesh with a steel bar diameter of 6-10mm (for example, 8mm) and a steel bar spacing of 150-250mm (for example, 200mm) are arranged in the C30 antifreeze concrete material, with a horizontality of ±5mm, to form a stepped shape. The construction method can be cast-in-place or prefabricated assembly. During construction, a construction method of cutting seams every 6m×6m with a seam width of 20mm and a depth of 25mm can be adopted, and the seams can be filled with weather-resistant sealant.

[0051] Furthermore, in the functional layer 200 of the ski slope anti-slip ramp structure of the present invention, a waterproof additional layer 208 is provided at all corners.

[0052] like Figure 1 As shown, in the anti-skid ramp structure of the ski slope of the present invention, a snow layer 300 is covered on the above-mentioned functional layer 200, and the thickness of the snow layer 300 can be 600-1000mm. For example, the vertical thickness of the positive corner of the step of the functional layer 200 from the snow layer 300 can be 700mm, and the vertical thickness of the position near the negative corner on the horizontal surface of the step of the functional layer 200 from the snow layer 300 can be 990mm, thus completing the construction of the entire anti-skid ramp structure of the ski slope.

[0053] In some embodiments, the anti-skid ramp structure of the present invention further comprises a V-shaped insulation turn-up section 400 at the bottom of the structural layer 100. One straight side of the insulation turn-up section 400 is vertically positioned, while the other straight side aligns with the bottom ramp surface of the structural layer 100. This insulation turn-up section 400 comprises an outer rock wool sandwich panel 401 and an inner turn-up polyurethane insulation layer 402, further enhancing the design of the anti-skid ramp structure of the present invention.
