Technology of Submersion and Injection of a Cylindrical Reinforced Concrete Piling

摘要

Experimental submersion is described of a cylindrical reinforced concrete piling designed by the TsNIIS, 10 sections were made 6 m in length (for five 12-m rabbets), with external diameter of 1.55 m, weighing 95 m each. The rabbets were submerged to an experimental section, located on the shore. The ground, into which the piling was sunk, is characterized by the following properties: angle of natural slope of dry sand 34--37 degrees and wet -- 31--33 degrees; volume weight of sand 1.49--1.60 g/cm. The granulometric composition of the sand is given in the table. The Horizon mark of the ground waters is 6.5--7m. Submersion of the rabbets is accomplished in four stages.
