Abstract
Abstract A high pressure pipe consisting of a flexible high pressure hose which is attached at both ends to a tube. The tube is stiffer than the high pressure hose in order to allow the high pressure hose to be pushed into the ground without bending or buckling and thereby forming a hole in the ground.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
83 words
A high pressure pipe, comprising: a flexible high pressure hose; a tube, having smooth inner and outer sides, surrounded by the high pressure hose and defining a space therebetween; wherein the high pressure hose and the tube are permanently attached to each other at both ends, the tube being stiffer than the high pressure hose and having openings through the sides allowing communication between the space and the inside of the tube whereby liquid under pressure flows through the tube and the space.
Claim 2
Dependent Claim
83 words
A high pressure pipe, comprising: a flexible high pressure hose; a tube, having smooth inner and outer sides, surrounded by the high pressure hose and defining a space therebetween; wherein the high pressure hose and the tube are permanently attached to each other at both ends, the tube being stiffer than the high pressure hose and having openings through the sides allowing communication between the space and the inside of the tube whereby liquid under pressure flows through the tube and the space.
Claim 3
Dependent Claim
39 words
A high pressure pipe according to claim 1, wherein the high pressure hose has at least one of nonelastic threads and bundles of nonelastic threads which are woven at an angle relative to the longitudinal direction of the hose.
Claim 4
Dependent Claim
15 words
A high pressure pipe according to claim 1, wherein the tube is a metal tube.
Claim 5
Dependent Claim
16 words
A high pressure pipe according to claim 1, wherein the tube is a glass fiber tube.
Claim 6
Dependent Claim
39 words
A high pressure pipe according to claim 1, further comprising various lengths and couplings; wherein the various lengths are attached to each other by the couplings, the couplings being installed on the high pressure hoses of the various lengths.
Claim 7
Dependent Claim
69 words
A high pressure pipe, comprising: a flexible high pressure hose; a tube, having smooth inner and outer sides, surrounded by the high pressure hose and defining a space therebetween; wherein the high pressure hose and the tube are permanently attached to each other at both ends such that the space is in communication with the inside of the tube, and the tube is stiffer than the high pressure hose.
Claim 8
Dependent Claim
69 words
A high pressure pipe, comprising: a flexible high pressure hose; a tube, having smooth inner and outer sides, surrounded by the high pressure hose and defining a space therebetween; wherein the high pressure hose and the tube are permanently attached to each other at both ends such that the space is in communication with the inside of the tube, and the tube is stiffer than the high pressure hose.
Claim 9
Dependent Claim
63 words
A high pressure pipe, comprising: a flexible high pressure hose; a tube, having smooth inner and outer sides, surrounding the high pressure hose and defining a space therebetween; wherein the high pressure hose and the tube are permanently and sealingly attached to each other at both ends such that the space is sealed, and the tube is stiffer than the high pressure hose.
Claim 10
Dependent Claim
63 words
A high pressure pipe, comprising: a flexible high pressure hose; a tube, having smooth inner and outer sides, surrounding the high pressure hose and defining a space therebetween; wherein the high pressure hose and the tube are permanently and sealingly attached to each other at both ends such that the space is sealed, and the tube is stiffer than the high pressure hose.
Claim 11
Dependent Claim
87 words
A high pressure pipe comprising: various lengths, each length comprising a flexible high pressure hose, and a tube, having smooth inner and outer sides, surrounding the high pressure hose and defining a space therebetween; couplings connecting the various lengths to each other; wherein the high pressure hose and the tube are permanently and sealingly attached to each other at both ends, and the tube is stiffer than the high pressure hose; and wherein the couplings are exclusively installed on the high pressure hoses of the various lengths.
Claim 12
Dependent Claim
87 words
A high pressure pipe comprising: various lengths, each length comprising a flexible high pressure hose, and a tube, having smooth inner and outer sides, surrounding the high pressure hose and defining a space therebetween; couplings connecting the various lengths to each other; wherein the high pressure hose and the tube are permanently and sealingly attached to each other at both ends, and the tube is stiffer than the high pressure hose; and wherein the couplings are exclusively installed on the high pressure hoses of the various lengths.
Claim 13
Independent Claim
94 words
A device for making a hole in the ground, comprising: a flexible high pressure hose; a tube, having smooth inner and outer sides, surrounding the high pressure hose and creating a space therebetween, said hose and tube being permanently attached to each other at both ends; a nozzle connected to one end of the hose; means, connected exclusively to the other end of the hose, for directing fluid under pressure exclusively through the hose such that the space remains empty of any fluid; and wherein the tube is stiffer than the high pressure hose.
Claim 14
Independent Claim
94 words
A device for making a hole in the ground, comprising: a flexible high pressure hose; a tube, having smooth inner and outer sides, surrounding the high pressure hose and creating a space therebetween, said hose and tube being permanently attached to each other at both ends; a nozzle connected to one end of the hose; means, connected exclusively to the other end of the hose, for directing fluid under pressure exclusively through the hose such that the space remains empty of any fluid; and wherein the tube is stiffer than the high pressure hose.
