SOIL ROTATION EXCAVATION PRESSING TYPE PREFABRICATED STEEL POLE FORMED WITH EXCAVATION BLADE AND EXCAVATION SCREW UNDER-BRACING AND STEEL POLE CONSTRUCTION METHOD FOR SAME

摘要

The present invention relates to a prefabricated steel pole and, more particularly, to a soil rotation excavation pressing type prefabricated steel pole formed with an excavation blade and an excavation screw under-bracing and a steel pole construction method for the same. According to the present invention, in constructing a steel pole in a ground, rotational excavation by means of a lower excavation blade and an excavation screw is allowed simultaneously with pressing without using manpower-based excavation or excavation by means of a backhoe or an auger crane. As a result, it is possible to improve the quality of construction and to shorten the construction period and to reduce the construction cost by forming a solid ground with ease of construction. In addition, by making it possible to excavate and drill through the upper excavation screw under-bracing and firmly support on the ground without unnecessary excavation resulting from installation of a pole under-bracing, the function of the pole under-bracing can be provided even without an additional pole under-bracing. In addition, it is possible to prevent the slope displacement phenomenon by more rigid construction without damage to the ground and a decline in the support force of the ground due to excavation and refilling can be prevented.;COPYRIGHT KIPO 2018
