GROUND REINFORCEMENT EQUIPMENT FOR SMALL-DIAMETER STEEL PIPE CONSTRUCTION

摘要

The present invention relates to ground reinforcement equipment for small-diameter steel pipe construction which enables a user to perform reinforcement of the ground in a narrow space and can increase reinforcement force of the ground. The ground reinforcement equipment for small-diameter steel pipe construction comprises: a pile pipe which is inserted into the ground; a pile pipe insertion and grouting material injection apparatus which can apply vibration force, rotation force, and pressing force to the pile pipe and, at the same time, supply a grouting material; and a grouting material storage tank which supplies the grouting material. The ground reinforcement equipment for small-diameter steel pipe construction can reduce work time and increase an efficiency of processes since the apparatus, which can insert the pile pipe and inject the grouting material at the same time, is formed as one unit. The ground reinforcement equipment for small-diameter steel pipe construction is formed to be able to inject the grouting material during a process for inserting the pile pipe, can inject the grouting material into the whole ground, and thus can increase reinforcement of the ground. A support frame to be inserted in the pile pipe is formed. The pipe and the support frame function as piles in a space for which reinforcement of the ground has been performed by using the grouting material. Therefore, the ground reinforcement equipment for small-diameter steel pipe construction can increase reinforcement of the ground.;COPYRIGHT KIPO 2017
