Abstract:
A system for transporting a barrier having a plurality of barrier modules having passageways extending therethrough by employing a barrier transport vehicle inserted in the passageways to lift the barrier modules and move the barrier.
Abstract:
A lifting apparatus to be embedded within a precast concrete panel or slab to enable the panel to be lifted, positioned atop a road bed, and elevated above the road bed. A lifting apparatus is located at each corner of the panel. Each lifting apparatus has a threaded sleeve extending through the panel to receive a removable threaded lifting bolt by which to establish a lifting point at which a lifting force is applied to lift and position the panel. When the threaded lifting bolt is rotated completely through the threaded sleeve, a pushing force is applied against a base plate, whereby to elevate the panel above the road bed as is necessary to make the panel level with adjacent panels during the construction or repair of a roadway. Grout is pumped through the panel to fill the space between the panel and the road bed.
Abstract:
A permeable paving system having a base layer and a paving layer, in which the base layer is made of a plurality of substantially hollow structural modules having a rigid bottom wall and a substantially parallel to a rigid top wall retained in a fixed space relationship from each other by a plurality of spacers, in which the structural module has a plurality of side walls extending between the perimeters of the top wall and the bottom wall, in which the top and bottom walls have apertures to allow movement of fluids into and out of the structural modules, and in which the top wall has a plurality of guide lines configured for alignment of paving material, and/or as a guide for cutting the structural module. Alternatively, instead of guide lines, there may be string line posts connectable to an element of the permeable paving system configured to extend above the top wall of said structural module and configured for establishing elevations of paving materials, and/or alignment of paving materials.
Abstract:
A paver may include a paver body and at least two slots running through the paver body from one side to another side. The slots may be parallel to an upper surface of the paver body. The slots further may be aligned according to the paver's orientation in a larger paver pattern such that, when multiple pavers are assembled according to the pattern, the slots of individual pavers cooperate to generate extended channels throughout the pattern. Thus, the principles of the present invention permit manufacturers to assemble paver mats made of a plurality of the pavers weaved together by a plurality of fastening cables that fit within one or more extended channels. In one embodiment, a core puller may be used to create slots in the paver body.
Abstract:
Paving system for mechanically paving with irregular paving stones, the paving system comprising a pre-ordering part (3; 10) for pre-ordering a set of irregular paving stones in an ordered configuration suitable for laying and a transferring part (5; 11) for transferring the set of irregular paving stones in the ordered configuration onto a foundation bed (7). The pre-ordering part and/or the transferring part is provided with a plurality of auxiliary guide rails (2; 18) provided for being accommodated in oblong recesses which are provided in the bottom sides of the stones from one lateral side up to another lateral side for overcoming differences in the thickness of the stones. The auxiliary guide rails extend at regular distances from each other, chosen to correspond with the spacing between the recesses, and have a predetermined shape, chosen to be complementary to that of the recesses.
Abstract:
System and apparatus for repair of concrete surfaces, and a method of using the same, having slab removal plates, slab replacement plates, slab transport/replacement frame carrier vehicles, slab injection/guide collars for application of fluid binding material as support for the replacement slabs, and microprocessor controlled global satellite coordinates, wireless transmission, and bar code identification for slab replacement.
Abstract:
A method and device for collecting a layer of concrete paving bricks forming a brick disk in the form of a stretcher bond which may be used as one setting unit, is characterized in that the layer of the paving bricks is clamped together laterally with a collecting clamp with respect to their longitudinal axes for aligning purposes and, after releasing the collecting clamps, each row of bricks is individually clamped to their respective position at their head ends with clamps. The clamps with the clamped rows of bricks are then displaced with respect to each other in a parallel direction to achieve the desired setting arrangement and the collecting clamp is again engaged.
Abstract:
A machine for assisting in the laying of courses of blocks to form a ground covering layer in erosion control systems has a flexible apron on which the blocks are laid, a frame attached to one side of the apron, and two spaced and independently actuable pusher bar assemblies, which can act between the frame and the blocks to position the blocks, steer the machine, and withdraw the apron from beneath the blocks.
Abstract:
A gripper device for a layer of brick mouldings arranged in rows comprises outer jaws arranged to grip opposite sides of the layer, the outer jaws being fixed against displacement longitudinally of the rows. A first, fixed, intermediate jaw is arranged between two pairs of rows, and second intermediate jaws are arranged between the individual rows of the two pairs of rows. The second jaws are displaceable longitudinally of the rows whereby to orientate the rows of mouldings into herringbone configuration.
Abstract:
A METHOD OF CONVENIENTLY FORMING A SUPPORTING PAD IS ACCOMPLISHED BY IMPREGNATING A FIBROUS MAT WITH A CURABLE PLASTIC FORMULATION AND TRANSPORTING THE IMPREGNATED MAT TO A DESIRED SITE, WHERE IT IS CURED. THE IMPREGNATED MAT IS GATHERED INTO THE FORM OF A DEFLATED BALLOON FOR TRANSPORT TO THE SITE AND THEN INFLATED AT THE SITE TO ENSURE THAT THE MAT IS EFFICIENTLY DEPLOYED. ADDITIONALLY, THE MAT IS STRETCHED TO A SUBSTANTIALLY FLAT CONFIGURATION AT THE SITE BY THE INFLATION OF A CLOSED TUBE EXTENDIN PERIPHERALLY OF THE MAT.
