摘要:
To provide rock fall prevention structure and rock fall prevention method capable of preventing the collapse of surface layer and preventing the falling of identified rock masses. Slope (1) is covered with a net assembly (2) constructed of rope materials (3) and (4) combined in intersectional directions and a wire net connected thereto. The rope materials (3) and (4) of the net assembly (2) are anchored into slope (1) using anchors (6). The anchors (6) are inserted into slope (1) to stabilize a surface layer of the slope (1), giving the anchors (6) and the net assembly (2) a strength able to suppress the movement of identified rock masses (22) at slope (1). Using the anchors (6) will be able to prevent the surface layer of slope (1) from collapsing and at the same time, using the anchors (6) and the net assembly (2) will be able to suppress the movement and falling of the identified rock masses (22) at slope (1).
摘要:
An improved element for forming ground covering, restraining and reinforcing structures, comprising a lower wall, an upper wall and a front wall connected in an articulated manner, at one of its end edges at least, to an edge of the lower wall or the upper wall.
摘要:
The subject of the invention is an element (1) for forming ground covering, restraining and reinforcing structures, particularly for forming retaining walls. The element (1) is constituted by a single wire-netting panel and is divided into a bottom portion (301), an intermediate front restraining portion (101), and a top end covering portion (201). These portions are delimited by reinforcing bars (2, 3) which are inserted in the mesh of the wire netting and which extend along the front portion (101) or define, between the portions (101, 201, 301), the predetermined bend lines for the formation of a substantially channel-shaped restraining element with a substantially vertical or inclined front wall. The structural element is filled with earth, stones or combinations of earth and stones (7, 7') and several channel-shaped layers each formed by an element (1) can be laid on top of one another to form retaining structures.

Protective netting comprises cables (11, 12) crossing in pairs and defining intersection points (10) at which the pairs of cables (11, 12) are fixed together by connection means (13, 14, 15, 16) comprising two first wires (13, 15) each of which has windings around a respective cable (11, 12) on either side of an intersection point and extends across the other cable (12, 11) in order to restrain it at the intersection point. The connection means further comprise at least two further wires (14, 16) wound around respective cables and inserted between the windings of the two first wires (13, 15) so as to form groups of turns disposed in the vicinity of each intersection point.
摘要:
A fibre (F) for reinforcing concrete comprises a length of metal wire having a substantially straight central part (E) and offset anchoring parts (T) at its opposite ends, each of which includes an initial straight portion (C) parallel to the central part (E) and offset laterally therefrom, a final straight portion (B) coaxial with the central part (E), and two opposed oblique portions ( D₁ D₂ ) connecting the initial straight portion (C) to the central part (E) and to the final straight portion (B), respectively.
摘要:
A reinforcement element for constructing earth covering, containment and reinforcement structures, in particular for constructing support walls, said reinforcement element comprising a reinforcement web(18) which is formed by a mesh, wherein said reinforcement web is adjacent and secured to a containment structure comprising at least one front face (13) made of double-torsion metal mesh, wherein a front panel (20) of electro-welded mesh is fixed to the front face (13), preferably by means of metal fasteners (20), such as clips or C-rings.
摘要:
A structure for restraining debris in a stream, including lateral walls, which delimit between them a flow section in a bed of the stream. This flow section includes an upper portion that includes set between the lateral walls, a structure for retaining material arriving from upstream, and a lower portion that identifies an opening for outflow.
