CONSOLIDATING AND LEVELLING WEIGHT FOR UNDERWATER RUBBLE-MOUND FOUNDATION

摘要

PURPOSE:To effectively consolidate and level through application of vibration on a weight plate, by a method wherein a support form fabricated from steel materials, a weight plate secured to a lower end, and a removable vibrator applying vibration on the weight plate, are provided, and graduations are marked in the direction of the height of the support form. CONSTITUTION:A wire rope 17 connected to a vibrator 15 is engaged with a hook 18 of a crane to lift up and down a consolidating and levelling weight (a). Vibraton is exerted on a weight plate 2 through a steel pipe 9 with the aid of the vibrator 15. A top end is consolidated through application of vibration on the weight plate 2 as the lifting-down height of the weight (a) is regulated, the height of the consolidated top end is measured again, and the top end is further consolidated for compaction until the measurement attains a design height. This permits detection of a consolidating distance of the top end and the direction of projection and recess, and since the support form has a low center of gravity and high safety, consolidation, which is conducted in a condition that the support form is erected on the top end, can be smoothed and a consolidated work can be effectively carried out.
