Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
164 words
A method of providing a pile in a ground formation having a high resistance to movement, comprising the steps of: A. driving a perforated tubular body into the ground formation, B. injecting a fluid substance includiNg a liquid isocyanate through the perforated tubular body under sufficient force to cause it to pass through the perforations and to enter the soil surrounding the tubular body, the fluid substance which, when coming in contact with water, reacts therewith to produce a water-insoluble solidified substance while liberating gas, a diluent for the fluid substance, and surface active agent, which does not react with the fluid substance and which facilitates the association between the fluid substance and water and serves to improve the stability of foams formed by the fluid substance and the liberated gas, C. reacting said fluid substance with the water in the ground formation to produce a water insoluble substance and liberate gas, and D. consolidating the ground surrounding the pile into a first mass.
Claim 2
Independent Claim
164 words
A method of providing a pile in a ground formation having a high resistance to movement, comprising the steps of: A. driving a perforated tubular body into the ground formation, B. injecting a fluid substance includiNg a liquid isocyanate through the perforated tubular body under sufficient force to cause it to pass through the perforations and to enter the soil surrounding the tubular body, the fluid substance which, when coming in contact with water, reacts therewith to produce a water-insoluble solidified substance while liberating gas, a diluent for the fluid substance, and surface active agent, which does not react with the fluid substance and which facilitates the association between the fluid substance and water and serves to improve the stability of foams formed by the fluid substance and the liberated gas, C. reacting said fluid substance with the water in the ground formation to produce a water insoluble substance and liberate gas, and D. consolidating the ground surrounding the pile into a first mass.
Claim 3
Dependent Claim
44 words
A method of providing a pile in a ground formation as claimed in claim 1, wherein said tubular body is left in the ground to function as the pile which has resistivity against the external force applied in the direction of longitudinal axis thereof.
Claim 4
Dependent Claim
66 words
A method of providing a pile in a ground formation as claimed in claim 1, comprising the further steps of withdrawing the tubular body longitudinally of its soil penetration before the initial charge of the fluid substance injected in the ground is consolidated and thereafter introducing secondary charges of the fluid substance sequentially while withdrawing the tubular body to thereby produce a vertically extending consolidated mass.
Claim 5
Dependent Claim
32 words
A method of providing a pile in a ground formation as claimed in claim 3, comprising the further step of constructing a wall from a row of interconnected vertically arranged consolidated masses.
Claim 6
Dependent Claim
73 words
A method of providing a pile in a ground formation as claimed in claim 1, wherein said tubular body comprises a conical drive portion at one end and open at the other end, a plurality of perforations extending through the wall of said tubular body, said perforations being inclined at an acute angle D to the axis of the length of said tubular body and relative to the driving direction of said pipe.
Claim 7
Dependent Claim
103 words
A method of providing a pile in a ground formation as claimed in claim 1, wherein said tubular body comprises an open ended hollow tubular member having an inner wall, a solid, conical drive plug provided with a portion complemental to the inner wall of said tubular member, and said plug being arranged to be parted from engagement with one end of the tubular member by pulling back the tubular member, thus making a gap between the open end of the tubular member and the end of the drive plug and introducing the fluid substance under pressure through the gap into the soil.
Claim 8
Dependent Claim
76 words
A method of providing a pile in a ground formation as claimed in claim 1, wherein said tubular body has a principal diameter dimension at one end of which is positioned a drive means, said tubular body further including a perforated neck portion of lesser diameter than the principal diameter thereof, said perforated neck portion arranged in proximity to the drive means and its perforations being thereby protected from clogging with soil during the driving operation.
Claim 9
Dependent Claim
31 words
A method of providing a pile in a ground formation as claimed in claim 1, wherein the fluid substance further comprises a liquid organic silane derivative and a fine powdered carbide.
