Abstract

A self-propelled pile-driving device comprises a support frame, a pile- driving assembly supported on the frame and including a driving device and a vibratory device. The driving device and the vibratory device are configured to drive a pile into the ground by applying pressure and vibrations, respectively. The device further comprises a pressure sensor and a sensor for detecting the rate at which the pile moves forward, which are operatively connected to the driving assembly so as to activate the driving device and the vibratory device, either selectively or in combination, depending on pressure values and rates of forward motion detected.

Abstract

A method and associated injection kit for mitigating the risk of liquefaction of ground T to be consolidated having an upper interface surface S, which provides for the production of at least one hole (2) in the ground T to be reached or towards volumes of the ground T, injecting an expanding resin (3) into the at least one hole (2) by means of the injection device (3), activating the expanding resin (3), conglomerating the ground T by means of the expanding resin (3), connecting portions of the ground T to each other, the expanding (resin 3) having an expansion relationship R between a final free volume Vfin and an initial free volume Vin less than (5).

Abstract

There is described a method of consolidating foundation soils and/or building sites in general, which comprises injections of expanding chemical products which are projected and carried out by means of monitoring the effects which are progressively measured in the soil in the course of treatment by means of sequential tomographies of the electrical resistivity. Those consolidating injections will be carried out until the percentage variation of the electrical resistivity Δρ(%), measured in quasi-real time in the soil being treated and always with respect to the initial condition before the injection will not constitute sequential gradients (Nth) which differ from the preceding one (N−1) for variations contained in the range ±5%.
