METHOD OF CONSTRUCTING REINFORCED CONCRETE UNDER GROUND, STRUCTURES, SUCH AS FOUNDATIONS PILES, DIAPHRAGM WALLS AND A DEVICE THEREFOR.

摘要

A method of constructing reinforced concrete under ground structures, such as foundations, piles, diaphragm walls, comprising casting the structure in the form of sections in situ and or using precast sections of the structure, of predetermined  convenient  lengths,  one  by  one,  suspended from a frame, lowering the said section into the ground of a. pre-bored hole or trench, casting the second section in situ and|or using a second precast section in place of the section which has been lowered, lowering the said second section by means of the said frame and repeating the sequence of these steps until the desired length of a structure of monolithic construction is completed.
