Also disclosed are drainage units and methods.

A protective barrier includes an angle bracket having a length extending from a first end to a second end of the protective barrier. The angle bracket includes a first elongate leg member having a first edge extending along the length of the angle bracket, the first elongate member having a first side configured to be mounted to a surface, a second elongate leg member extending along the length of the angle bracket and substantially perpendicular from the first elongate leg member, and an impact absorber extending from the first end to the second end of the protective barrier, the impact absorber being compressible and configured to be disposed on the angle bracket.

A system for assembling a road comprises a plurality of plastic support structures and a plurality of road deck elements. Each of the support structures comprises a base plate and at least one column extending, or for extending, upwardly from the base plate for supporting at least partly one of the road deck elements. Each of the road deck elements is configured such that in an assembled and as road useable condition of the system rainwater predominantly flows away over the road to one or more positions next to the road, and/or to a slit-sized interruption of the road across the road.

Structural cells and matrices using the structural cells for positioning below a hardscape that define a void space therein, the structural cells, matrices using the cells and methods of assembly allowing in one embodiment the introduction of a structural fluid such as concrete to provide an alternative structural cell and matrix product. In one embodiment a structural cell assembly is described comprising a structural cell with a plurality of legs integrally linked to a frame at a first frame end, the frame linking the legs together and the frame defining a generally flat plane with the legs extending substantially orthogonally away from the first frame end about the frame flat plane to a leg terminal end; and a separate plate engaging the legs, the separate plate comprising linked sockets, each socket engaging the leg terminal end; and/or linked sockets, each socket engaging the leg frame ends or a part thereof.

An impact-absorbing assembly includes a covering layer being one or more of artificial turf, rubber mats, polymer mats, short pile carpeting, particulate infill, wood chips, and ground rubber chips. Also included is a layer of underlayment panels positioned beneath the covering layer. The panels have a panel section with a plurality of drain holes formed therethrough. A top surface of the panels is configured to support the covering layer. A bottom surface of the panels has a plurality of bottom projections that cooperate to define bottom channels suitable to permit water flow across the bottom surface, the bottom channels being in fluid communication with the panel drain holes. The bottom projections define a first spring rate characteristic that is part of a first stage and a second spring rate characteristic is part of a second stage, the first stage having a smaller volume of material than the second stage.

The present invention provides a curb for measuring the flood depth in an urban area, more particularly, to a curb for measuring the flood depth in an urban area, which is configured to demarcate the boundary between a vehicular roadway and a pedestrian sidewalk to measure the flood depth so that the flood depth in the urban area can be measured without the necessity for additional installation of a separate structure. In particular, the present invention has an effect in that an air contact type water level gauge is installed in a first space of a main body to measure the flood depth, i.e., the level of flooding water based on the internal air pressure of a cylindrical tube so that a pressure sensor is not brought into close contact with the flooding water to prevent corrosion of the pressure sensor, thereby reducing the maintenance and repair costs.

An edge restraint and method of use where the edge restraint has a vertical wall for retaining segmental pavement in an installation placement and a horizontal base having a plurality of teeth extending therefrom and providing discrete focused points for providing friction between the edge restraint and an installation surface to prevent horizontal movement of the edging in at least one direction with respect to the installation surface. A leading edge of the base is installed under a first surface with the wall providing a barrier between the first surface and a second surface for engaging the teeth with a third surface to prevent movement of edging in a horizontal direction away from the first surface.

A road gutter having a dust collection function, consisting of a gutter groove (11) and a cover stopper (10) that covers the gutter groove (11). The side surface of the cover stopper (10) is “T”-shaped. Plugs (10b) of the cover stopper (10) are embedded in the gutter groove (11), and a shoulder (10c) of the cover stopper (10) is supported on platforms (11c) formed by the left and right walls of the gutter groove (11) to bear the weight of the whole cover stopper (10). The front surface of the cover stopper (10) is inverted “U”-shaped, and forms a dust absorption channel (10a) with a solid part of the gutter groove (11). The dust absorption channel (10a) communicates the gutter groove (11) with an external space. Road dust and mess enter the gutter groove (11) from the external space by means of the dust absorption channel (10a) under the drive of an external force, and fall to the bottom of the gutter groove (11).

A curb former (10) includes a rotatable drive shaft (20), a gutter drum (80), and a curb profiling drum (100). The gutter drum (80) is secured to the drive shaft (20) such that the drive shaft (20) and gutter drum (80) rotate together. The curb profiling drum (100) is detachably secured relative to both the drive shaft (20) and the gutter drum (80). This configuration allows one curb profiling drum (100) to be replaced with another curb profiling drum (100) to change the profile of a curb resulting from a curbing operation using the curb former (10).
