摘要:
A concrete structure for replenishing an aquifer and a method for constructing the same is provided. The structure is comprised of a pavement layer with surface drains that extend through the pavement layer and into an aggregate leach field. The leach field includes leach lines spanning the leach field. An aggregate drain extends from the leach field into a sand lens. Precipitation which falls upon the structure thus flows through the surface drain, absorbed into the aggregate leach field, and transported to the aggregate drains by way of aggregate leach lines. The water is then absorbed into the sand lens, ultimately replenishing the aquifer. Existing conventional pavement structures are retrofitted by the removal of a section of the pavement, and filling the same with porous concrete.

An open modular ditch liner includes a plurality of open liner sections and at least one channel alignment key. The at least one channel alignment key is sized to receive a thickness of two adjacent open liner sections. An erosion barrier insert may be placed between the ends of two adjacent open liner sections. A radius liner insert may be placed between the ends of two adjacent open liner sections. The width of an open liner section may be expanded with a plurality of side connection keys and a plurality of expandable liner sections. A plurality of pitch expandable liner sections may be inserted between the plurality of open liner sections and expandable liner sections. At least one side of the plurality of open liner sections and expandable liner sections may be mitered.

The invention relates to a ground covering element for making a ground gutter, with an upper side where a groove portion is provided, a lower side, two oppositely disposed longitudinal sides extending in the longitudinal direction of the groove portion, a first face supporting a first registration section of the groove portion, and, in opposed relation, a second face supporting a second registration section of the groove portion, such that the faces each provide at least one projecting portion extending in the longitudinal direction of the groove portion, and at least one receptive portion shaped at recess in the longitudinal direction of the groove portion, in which projecting portion can be brought into engagement with a recessed portion of a neighbouring ground covering element, and each recessed portion can be brought into engagement with a projecting portion of a neighbouring ground covering element, such that an edge formed between the lower side and the first face has a configuration which is essentially congruent with the configuration of an edge defined between the lower side and the second face, and wherein the edges are not parallel with one another.

An anti-icing system may maintain a thin layer of solution on top of pedestrian reception areas to prevent frozen precipitation from remaining frozen on the pedestrian reception areas. This greatly reduces the slippery surfaces that pedestrians would otherwise encounter when using the walk-on surface.

A gutter curb for paved roadways is constructed of an assembled series of elongated sections of gutter curbs connected together end to end, which are assembled along at least one side of a road bed. The gutter curb sections are molded from rubber from recycled tires and are held to the adjacent roadway pavement by tie rods passing through opposite sides gutter curb sections and projecting into the pavement itself to be securely held thereto.
摘要:
A floor covering main body comprising an intermediate channeled surface. A plurality of non-contiguous but adjacent lugs extends upwardly from the intermediate channeled surface. A substantially planar composite upper surface is disposed above the intermediate surface and is defined by the top surfaces of the lugs. The intermediate channeled surface carries or channels liquid away from the upper walking surface. A plurality of floor covering main bodies can be aligned to form a flooring system. In another configuration, some or all of the lugs may be contiguous.

Modular drainage components include a curb liner section, a culvert receiver, a secondary connector, a trapezoidal ditch liner section and a curved ditch liner section. A plurality of curb liner sections are inserted between a roadway and a strip of land to block overflow from the roadway. The culvert receiver is placed between a open ditch liner section and a culvert. The secondary connector provides a flow path for secondary flow to or from a primary flow. A plurality of trapezoidal ditch liner sections or a plurality of curved ditch liner sections may be placed end to end to form a radiused path of flow.
