Abstract
Abstract Device for reinforcing hydraulic structures, especially dams, groins, rinsing fields, and for transporting materials which can be transported by means of pumps or similar devices. The device consists of a hose of plastic material provided at both ends with sockets for the inlet and outlet of a sand-in-water mixture and having a length which corresponds to a multiple of its diameter.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
88 words
A device for reinforcing hydraulic structures such as dams, groins, flooded flatland fields, etc., which consists of a hose with inlet and outlet sockets at its ends, the length of which corresponds to a multiple of its diameter, said sockets being of smaller diameter than said hose and radially spaced from the axis of said hose, said hose being woven from plastic bands and being water permeable at the intersection of said woven plastic bands but capable of retaining sand flushed to the same as a sand-inwater mixture.
Claim 2
Independent Claim
88 words
A device for reinforcing hydraulic structures such as dams, groins, flooded flatland fields, etc., which consists of a hose with inlet and outlet sockets at its ends, the length of which corresponds to a multiple of its diameter, said sockets being of smaller diameter than said hose and radially spaced from the axis of said hose, said hose being woven from plastic bands and being water permeable at the intersection of said woven plastic bands but capable of retaining sand flushed to the same as a sand-inwater mixture.
Claim 3
Dependent Claim
21 words
A device according to claim 1, wherein face parts of the hose are woven in one piece with the hose body.
Claim 4
Dependent Claim
20 words
A device according to claim 1, wherein the sockets are seWed, welded, or flanged with the body of the hose.
Claim 5
Dependent Claim
17 words
A device according to claim 1, wherein the hose has a diameter of at least 0.3 meter.
Claim 6
Dependent Claim
17 words
A device according to claim 1, wherein the hose has a length of at least 10 meters.
Claim 7
Dependent Claim
25 words
A device according to claim 1, wherein the woven structure of the face part of the hose is stronger than that of the hose body.
Claim 8
Independent Claim
105 words
A device for reinforcing hydraulic structures, such as dams, groins, flooded flatland fields, etc., which consists of a hose body having inlet and outlet sockets attached to said hose body, said sockets being of smaller diameter than said hose and radially spaced from the axis of said hose, said hose body containing as an integral part of same a face portion, a plurality of interwoven plastic bands forming said hose body and a plurality of apertures at intersections of said interwoven plastic bands, whereby sand from a sand-in-water mixture introduced into the hose body is retained and said sand-filled hose body reinforces said hydraulic structure.
Claim 9
Independent Claim
105 words
