Abstract Piling projecting at the upper part through tundra are protected from ground movement in an upward direction due to periodic freezings and thawings of the tundra by being fixed to conically shaped collars extending down from the surface of the earth, with the base of the cone down. The conical portion thus becomes a part of the pile, mechanically speaking. If desired, the conically shaped part may be an integral part of the pile. As the liquid part of the tundra surrounding the upper part of the pile freezes, it expands radially inward against the conical surface, resulting in a downward force of sufficient magnitude to keep the pile from ''''heaving'''', i.e., moving vertically upward due to freezing effects in the ground.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
87 words
A tapered member for use in minimizing heave in a pile driven into periodically freezing and thawing tundra comprising a. a tapered solid body the transverse dimensions of which gradually increase from top to bottom thereof, said body defining a central axial hole large enough for the pile to pass through, the bottom part of said tapered body decreasing abruptly to the dimensions of said central axial hole, and b. clamping means connected to said tapered body for fixing said body in force-transmitting relationship to said pile.
Claim 2
Dependent Claim
87 words
A tapered member for use in minimizing heave in a pile driven into periodically freezing and thawing tundra comprising a. a tapered solid body the transverse dimensions of which gradually increase from top to bottom thereof, said body defining a central axial hole large enough for the pile to pass through, the bottom part of said tapered body decreasing abruptly to the dimensions of said central axial hole, and b. clamping means connected to said tapered body for fixing said body in force-transmitting relationship to said pile.
Claim 3
Dependent Claim
79 words
Apparatus in accordance with claim 1 in which said tapered body forms substantially the frustum of a cone the directorix angle of which is within the range of approximately 3* to approximately 30*, and said bottom part of said body is reverse tapered with respect to the upper portion thereof with a directorix angle substantially greater than that of said tapered body, so that axial length of said bottom part is substantially smaller than that of said tapered body.
Claim 4
Dependent Claim
50 words
Apparatus in accordance with claim 2 in which said tapered body forms substantially the frustum of a cone, the directorix angle of which is within the range of approximately 3* to approximately 30*; the maximum diameter of said tapered body being at least three times the diameter of said pile.
