To provide a roadway boundary block and a road structure capable of improving precision docking to a stop easily without depending on high driving ability of a driver. A roadway boundary block 100 includes an upper portion 120 arranged to be continued to a roadway 10. An incline of the upper portion 120 against a horizontal direction is larger than an incline of the roadway 10 against the horizontal direction in a road width direction. A width of the upper portion 120 along the road width direction is larger than a tire ground contact width of a bus 50 travelling on the roadway 10 and smaller than a tread of the bus 50.

A water collecting boundary block includes a body having an opened upper portion and a space portion formed therein, a grating which is seated on the body, and through which a plurality of rainwater inlets are formed, and a drain part formed at one side of a lower end of the body so as to be connected to the space portion, to provide water stored in the space portion to a ground.

A polymer based combined kerb drainage element (1) and a method for manufacturing such are provided. The combined kerb drainage element (1) comprises a first moulded component (2) having side walls (2a, 2b) that define a first longitudinal channel and a second moulded component (3) having side walls (3a, 3b) that define a second longitudinal channel. The side walls (3a, 3b) of at least one of the moulded components (3) are linked by a living hinge (4) such that said hinged side walls (3a, 3b) can be aligned with the side walls (2a, 2b) of the associated moulded component (2) to construct the combined kerb drainage element (1) with an internal conduit (16).

Surface water drainage Systems are known, comprising a water drainage body which is elongated by individual elements that can be placed next to one another, and which can be installed in the ground. The individual elements (1-6) comprise an inlet section which is arranged in an upper region of the individual elements (1-6) in such a way that water can flow into the inlet section. A first pipe section (20) is provided, arranged below the inlet section and communicating with same via transition Systems. According to the invention, in order to increase the drainage power, at least one further second pipe section (30), communicating with the first pipe section (20), is to be provided below or next to the first pipe section (20), wherein all the pipe sections (20, 30) can be sealingly connected to corresponding pipe sections (20, 30) of further individual elements (1-6).

The present disclosure is directed to a curb for providing electricity to one or more devices on a street or a sidewalk. The curb includes a rigid curb housing for storing at least one power source or power source connector configured to be electrically coupled to a power source. The curb additionally includes a top plate removably attached to the rigid curb housing, the top plate configured to electrically couple at least one power outlet to the at least one power source or power source connector.

An edge restraint system for pavers includes two or more interlocking edge restraints, a spike, and optionally, a grid clip. The interlocking edge restraints each have a vertical member and a horizontal member buttressed by a gusset. The horizontal member has a first engagement area having a first alignment button, a second alignment button, and a first spike aperture. The horizontal member has a second engagement area having a first alignment button aperture, a second alignment button aperture and a second spike aperture. The first and second interlocking edge restraints may be coupled together at the first and second engagement areas, and secured to the ground by inserting a spike and, optionally, a grid clip, screws, and a geogrid. The restraints can be cut to fit varying sized pathways, patios, driveways, and roads.

A vegetation maintenance system includes a permeable curb, a water-diversion layer, a water-storage layer, a nutrient layer, and a vegetation-planting trough. The permeable curb is located abutting roadside pavement edge of a road along a road direction. The water-diversion layer is located on a side surface of the permeable curb and is disposed close to a bottom of the permeable curb. The water-storage layer is disposed at one side of the water-diversion layer away from a surface of the road, and is configured to store water. The nutrient layer is disposed at one side of the water-storage layer away from the water-diversion layer, and is configured to provide water, soil, and nutrients for growth of vegetation. The vegetation-planting trough penetrates through the water-diversion layer and the water-storage layer, is embedded in the nutrient layer, and is configured for vegetation planting.
