Abstract

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.

Description

technical field [0001] The present application relates to a construction method of a bobsled arena using a composition of high-performance wet shotcrete, in particular to a method of constructing a bobsleigh field using a composition of high-performance wet shotcrete. The composition of high-performance wet shotcrete By utilizing the high-performance wet shotcrete composition containing silica fume and AE agent, it has the advantages of increasing the pumpability (Pumpability) by securing an excessive amount of air before pouring, and increasing the stickiness (Shotability) by reducing the amount of air after pouring. ) and other high constructability, high strength and high durability. Background technique [0002] Wet shotcrete is a concept different from dry shotcrete. It refers to the concrete that is sprayed and pasted after adding water to the spraying device when mixing materials, and adding air to the nozzle to increase the spraying speed. It is a construction metho...
