Explosive pile device for increasing pile capacity

Abstract

The invention is related to a device having an explosive device wherein said device is located at a tip or attached along a length of a pile, and the method using thereof. The device comprises at least one main pipe connection and a bearing pipe, both of which have same diameters as to the pile, whereas the explosive device is installed within the bearing pipe. After a controlled detonation of the explosive device, the bearing pipe expands both in diameter and volume, which has cross-sections of ellipse-like or lantern-like shapes.

1 . A device having an explosive device installed at a tip or along a length of a pile, comprising: at least one main pipe connection and a bearing pipe, wherein the connection is connected to the bearing pipe respectively; the explosive device is located in the bearing pipe; and after an explosion of the explosive device, the pile maintains its integrity and no break to the device and the pile. 
     
     
         2 . (canceled) 
     
     
         3 . The device of  claim 1 , further comprises laminated structures mounted to both ends of the bearing pipe, wherein each of said structures comprises at least two layers and at least two layering materials, of which one layering material has low sound impedance relative to other layering materials. 
     
     
         4 . The device of  claim 1 , further comprising fiber reinforced composite structures fixed to both ends of the bearing pipe. 
     
     
         5 . The device of  claim 1 , further comprising: a plurality of reinforcing rings on the bearing pipe.

         7 . (canceled) 
     
     
         9 . (canceled) 
     
     
         10 . The device of  claim 1 , wherein the shape of the bearing pipe after blasting is of elliptic- or lantern-shape. 
     
     
         11 . A device having an explosive device installed at a tip or along a length of a pile, comprising: a main pipe connection, a bearing pipe and an end cone section; wherein the connection is connected to one end of the bearing pipe, the send cone section is connected to the other end of the bearing pipe; and, the explosive device is located in the bearing pipe; and, after blasting, the bearing pipe's shape is controllable, the bearing pipe's integrity is maintained and no break is made to the device and the pile. 
     
     
         12 . (canceled) 
     
     
         13 . The device of  claim 11 , further comprising: laminated structures mounted to both ends of the bearing pipe, and each of the laminated structures comprises at least two layers and at least two layering materials, wherein one layering material has low sound impedance relative to other layering materials. 
     
     
         14 . The device of  claim 11 , further comprising fiber reinforced composite structures fixed to both ends of the bearing pipe. 
     
     
         15 . The device of  claim 11 , further comprising: a plurality of reinforcing rings on the bearing pipe. 
     
     
         16 . (canceled) 
     
     
         17 . The device of  claim 11 , wherein the explosive device holds explosive from any of the following: TNT, RDX, HMX, COMPOSITE B, Solid Propellants and Liquid Propellants. 
     
     
         18 . (canceled) 
     
     
         19 . The device of  claim 11 , wherein the shape of the bearing pipe after blasting is of elliptic- or lantern-shape. 
     
     
         20 . A method of using a device having an explosive device installed at a tip or along a length of a pile, wherein said device comprises at least one main pipe connection and a bearing pipe, comprising:
 a, attaching the device at the tip or along the length of the pile;   b, controlling the weight and shape of explosive in the explosive device;   c, detonating the explosive device underground; and,   d, maintaining the integrity of the bearing pipe and no break to the device and the pile.
