Modification Explanation

4.3.2 Structural design shall be done for an ice and snow landscape building which has a height ofmore than 10m or allows tourists to go inside for activities or has load exposed on top.

4.3.5 The masonry structures which tourists can directly touch shall be tucked or made into astaircase when their vertical height exceeds 5m.Meanwhile,the following requirements shall be observed:

1 Measures shall be taken against overturn and slippage;

2 The thickness of ice masonries shall not be less than 800mm and be constructed in layers.The cohesion-ratio of the seam shall be no less than 80%；

3 The thickness of snow masonries shall not be less than 900mm and shall be tamped in layers according to the design density value；

4 The distance between the vertical projection of the highest masonry or overhanging part and the outer edge of the landscape’s foundation shall be no less than 600mm.

4.3.8 The design of Ice and snow recreational activity item category shall follow the following requirements:

1 If the height of ice and snow buildings for climbing surpasses 5m,safety devices shall be incorporated,and security-tested devices shall be available.The maintenance devices for safety,an evacuation platform and channel shall be required on the top of the building.

2 The slideway of ice and snow slides shall be plain and smooth.In addition,the following requirements shall be met:

1) The width of the straight slideway shall not be less than 500mm,and the width of curveslideway shall not be less than 600mm; the slideway guardrail shall not be lower than 500mm,and the thickness shall not be less than 250 mm;

2)The slideway guardrail around the bend shall be heightened and reinforced.The guardrail in the curve parts shall not be less than 800mm.Caution signs shall be fixed in the turning slope change area.Buffer shall be provided at the slope end,and the length of the buffer shall be determined by field testing.At the ice-slide’s end,safety facilities shall be available；

3)For sliding activities,skating apparatus shall be applied when the slide length is longer than 30m.The average slope of the slideway without skating apparatus shall not exceed 25° and that with skating apparatus shall not exceed 10°；

4)The skating apparatus shall be made of durable light material and prove qualified through safety testing.

3 For special recreational activities involving ice bicycles,snowmobiles,ice bumper cars and snow bumper cars,safe and eligible products shall be used and protective facilities shall be provided.

5.1.3 For the height of the ice building more than 30m or that of the snow building more than 20m,sedimentation and deformation observation during the construction should be taken.

5.5.5 During the construction,monitoring the temperature of ice masonry should be carried out.When the temperature is higher than the design temperature,or the masonry water cannot be frozen,construction should be suspended and methods should be adopted to protect the ice landscape,such as using shading and wind-proofing,etc.
