Abstract:
The application relates to a ground-engageable surface (10) comprising a plurality of structural elements (12) arranged a series of partially overlapping rows (26-46). The structural elements of one row (26) are connected to structural elements of an adjacent row (28) such that each row is pivotable about its connection. The pivotable connection is provided by means of an elongate cylindrical rod (29) which extends through aligned bores (14,18) in the structural elements. The surface (10) may be stored in a rolled-up configuration for ease of deployment over soft or unstable ground. The resilient nature of the surface (10) helps to maintain contact with the underlying terrain and spread applied loads evenly.
Abstract:
An interlocking construction block has opposed ends each having a plurality of substantially planar bearing surfaces. The planar surfaces include perpendicular surfaces joined by surfaces at obtuse angles. The block is arranged to be complementary to other blocks in several different configurations.
Abstract:
The present invention relates to a road restoration block for covering eliminated pavements during various road constructions conducted by eliminating some of or the entire existing road pavements, and more specifically, to a road restoration block, which can quickly and safely cover the eliminated pavements by providing blocks that are simply carried, disposed, and disassembled with strong coupling power to the upper part of the eliminated pavements so that people and cars may pass even when the constructions are in progress, thereby providing a safe and pleasant construction environment by preventing the traffic congestion caused by the constructions. Further, the invention may maximize cost reduction for construction companies by preventing the increase of construction costs and waste of resources caused by temporary pavement works (provisional pavement works) that are currently in operation, and improve the construction quality and prevent poor construction. Consequently, the invention promotes reduction in the national budget, and is usable for emergent road restoration in case of national disaster and thus the safety and wealth of people can be protected.
Abstract:
In the manufacture of an articulated, predominantly concrete mat, which comprises concrete blocks (40) and a flexible geogrid (30) embedded in such blocks and in which the flexible geogrid defines flexible members (32) connecting such blocks to one another, an intermediate article being a concrete slab (20) is cast, in which a flexible geogrid (30) is embedded. The slab has relatively thinner portions (22), along which the slab is breakable to form such blocks and relatively thicker portions (24), which become such blocks when the slab is broken along the relatively thinner portions Preferably, the relatively thinner portions extend longitudinally and transversely, in a rectangular array, before the slab is broken along the relatively thinner portions.
Abstract:
In lawn covers made of paving stones (10) mutually separated by a relatively large gap, the paving stones are linked to each other so as not to move in relation to each other by a holding grid (11) imbedded in the paving stones (10) and composed of traction-resistant branches, so that traction forces are transmitted and the paving stones (10) are mutually secured as a linked group of paving stones by the holding grid (11). The set of paving stones is produced in an essentially classical concrete stone mould. A moulding box (19) arranged on a bearing board (28) or draw plate (29) is horizontally subdivided along the horizontal plane (33), forming a top partial moulding box (34) and a bottom partial moulding box (35). The holding grid (11) is clamped between both partial moulding boxes during concreting. When a group of paving stones is ready, the bottom partial moulding box (35) withdrawn from the concrete stone mould. The finished product can then be removed as usual from the mould.
Abstract:
A paving assembly (1) comprises a plurality of paving elements (2) interconnected by a reinforcing and interconnecting mesh (5) of plastics material. Adjacent paving elements (2) are joined by frangible links (15) which assist in spacing the elements (2) to define interstices (9) to receive bedding sand. The links (15) have fault line (16) along which the links (15) may be broken to accomodate articulation between adjacent paving elements (2), on fitting. A mechanical interlock is formed when the paving is in place and the faces of the link posts (15) re-engage. In some cases a paving assembly (100) may comprise paving elements (101) which do not have a joining mesh.

Abstract:
A vehicle-supporting surface incorporating at least one rail (102). The surface includes first and second panels (106A, 312) of compressible material that are arranged to be fitted together such that a surface of the first panel at least partially abuts a corresponding surface of the second panel. The first and second panels each include respective interengagable formations (126A, 310) at least partially embedded within them and located at their abutting surfaces. The interengagable formations are configured to at least partially counteract forces resulting from the compression of the panels in the region of the abutment.
