Abstract

Abstract A fascine capable of conforming to the contours of a supporting surface, comprises a core (1) of cylindrical pipes (2) loosely disposed within a surrounding flexible sleeve (3) comprised of similar pipes (4) transversely and continuously inter-connected by tensioned flexible ties (10-13). All the pipes (2 and 4) are capable of elastic cross-sectional deformation, the sleeve pipes (4) being held in diametral compression by the flexible ties (10-13) to provide increased resistance to external compression forces acting substantially perpendicularly to the direction of diametral compression, and the core pipes (2) being selected to have less resistance to deformation than the sleeve pipes (4) so as to absorb external point loading forces acting on the sleeve pipes. The fascine is suitable for use by both wheeled and tracked vehicles.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 93 words
A conformable fascine including a core (1) comprising a multiplicity of tubular core members (2) each capable of elastic cross-sectional deformation when subject to transverse compression forces, and all freely disposed in axially parallel relationship, and a sleeve (3) circumjacent the core comprising a multiplicity of axially parallel tubular sleeve members (4) all transversely and continuously interconnected by at least two axially spaced flexible tie means (10, 13) each disposed as a continuous loop; characterised in that the sleeve members (4) are conjointly maintained in transverse compression by the tie means (10, 13).
Claim 2
Dependent Claim 93 words
A conformable fascine including a core (1) comprising a multiplicity of tubular core members (2) each capable of elastic cross-sectional deformation when subject to transverse compression forces, and all freely disposed in axially parallel relationship, and a sleeve (3) circumjacent the core comprising a multiplicity of axially parallel tubular sleeve members (4) all transversely and continuously interconnected by at least two axially spaced flexible tie means (10, 13) each disposed as a continuous loop; characterised in that the sleeve members (4) are conjointly maintained in transverse compression by the tie means (10, 13).
Claim 3
Dependent Claim 42 words
A fascine as claimed in claim 1 characterised in that the sleeve members (4) are of circular cross-section, each having diametral perforations (5) through which the flexible tie means (10, 13) are threaded, thereby to maintain the sleeve members in diametral compression.
Claim 4
Dependent Claim 29 words
A fascine as claimed in either one of the preceding claims characterised in that the core members (2) have less resistance to cross-sectional deformation than the sleeve members (4).
Claim 5
Dependent Claim 48 words
A fascine as claimed in claim 3 characterised in that the core members (2) and the sleeve members (4) are all of similar material, all of circular cross section and all of substantially equal external diameter, the core members being of thinner wall thickness than the sleeve members.
Claim 6
Dependent Claim 31 words
A fascine as claimed in any one of the preceding claims characterised in that the sleeve members (4) contain reinforcement liners (14) located interjacent the axially spaced tie means (10, 13).
Claim 7
Dependent Claim 44 words
A fascine as claimed in any one of the preceding claims characterised in that the core members (2) are restrained from axial egress from the sleeve (3) by retaining nets (18) secured so as to extend across each end of the sleeve (3). -
Claim 8
Dependent Claim 31 words
A fascine as claimed in any one of the preceding claims characterised in that recovery fittings (15) are attached to the sleeve (3) at three or more equally spaced perimetral locations.
Claim 9
Dependent Claim 207 words
A method of constructing the conformable fascine claimed in Claim 2 including the steps of:- 8 a. arranging the sleeve members (4) side by side on a level surface with their diametral perforations (5) in alignment, b. threading a length of chain through each aligned set of perforations (5), c. securing one protrusive extremity of one of the chains to a tensioning means operative against the adjacent end sleeve member and applying an open-ended, slotted stop plate (17) to the other protrusive extremity, d. straining the chain into tension with the tensioning means so as to compress all the sleeve members conjointly, e. applying a second open-ended slotted stop plate (17) to the chain adjacent the end sleeve member nearest the tensioning means so as to maintain the compression, f. removing the tensioning means and the excess chain beyond the stop plates, g. repeating the steps c to f for each chain, h. bringing the two stopped ends of each chain together and joining them to form the continuous loop tie means (10-13) and thereby to provide the sleeve (3), i. removing the slotted stop plates from each chain, and j. loosely filling the interior of the sleeve (3) with a multiplicity of the core members (2).
