Mock Up Test on Construction Method, Filling Method,and Waterproof Performance using theInverted Construction Method of Underground Structure
Abstract

In the inverted construction method, one of the major methods adopted for placing joints, due to its
superior performance in construction,is the grouting method using a filling hose placed on the casting joint.
Concrete casting performance of the inverted construction method and construction performance of the fillingmaterial, filling method and water proof performance of the placing joint method were studied using a fullscale specimen of a basement level outermost column, outermost wall and inner column with temporary
encased steel.
The experiment showed that when using a hard mixed concrete in the drop down casting method leads topoor construction performance of the joint. Using a combination of highly-flowing concrete and first degree
filling material can make construction performance better for filling methods with difficult proportions.
Casting highly flowing concrete from only one side while consolidating it with the vibrator resulted inconcrete with excessive mortar coming up to the joint, thus casting from two sides is necessary. Inclining thecasting joint to 1/10 gave a better result in drop down concrete casting and filling method than a flat casting
joint. The rate of the air trapped area with a flat casting joint was 19〜20%,but with a 1/10 inclined casting
joint this reduced to 5%. The water proof performance of the joint conducted in this experiment showed,
joints where the water pressure is at a depth of 5m (0.05MPa) can be filled using a first degree fillingmaterial and joints where water pressure is at a depth of 30m (0.30MPa) can be filled using a second degree
filling material.
