CONSTRUCTION WORK OF STRUCTURE

摘要

PURPOSE:To construct structures having structurally high reliability by a method in which the free long portion of an anchor whose lower part is fixed to the ground is tensely introduced into and fixed to a structure on the ground's surface. CONSTITUTION:An earth anchor A is penetrated into an excavated pit 2 in the seabed ground 1. The upper free long portion 3a3 projected from the ground 1 is introduced into a jacket structure B, and a grout 7 is injected under pressure into the structure B and the pit 2 to fix the lower end 3a1 of the anchor A to the pit 2. The upper free long portion 3a3 of the twist steel wire 3 of the anchor A is tensed by a jack and fixed through a wedge 9 to the hole of the anchor head 8. The tension force of the head of the anchor A is transmitted as a compression force to the ground 1 through the head 8 and a distribution plate from the structure B. Tensile load to be applied to the anchor A is also transmitted to the grout 7 and the ground 1.
