METHOD FOR CONSTRUCTING A BOBSLEIGH COURSE USING A HIGH-PERFORMANCE WET-TYPE SHOTCRETE COMPOSITION

摘要

The present invention relates to a method for constructing a bobsleigh course using a high-performance wet-type shotcrete composition, and more particularly, to a method of constructing a bobsleigh course that uses a high-performance wet-type shotcrete composition which includes silica fumes and AE material, and which has increased pumpability prior to being deposited due to the presence of a superabundant amount of air, and increased shootability after being deposited since the amount of air present is decreased, thus imparting high constructability, high strength, and high durability to the composition. To this end, the method comprises: a framework-forming step of fixing a wire-mesh formwork, positioning a cooling pipe, strengthening adherence and holding strength, and installing a curvature-maintaining pipe; a shotcrete-laying step of laying the shotcrete composition; a first surface-finishing step of setting a curved surface and performing finishing using plastering; a second surface-finishing step of performing a rough surface finishing; and a wet curing step of performing wet curing.
