A prefabricated form for use in constructing a casting cured concrete curb having a plurality of engaging pieces in which adjacent engaging pieces are abutted. Each of the engaging pieces has a fixing rod insertion hole formed therein. A plurality of spacer insertion holes are formed longitudinally and aligned respectively with the fixing rod insertion holes. The plurality of plate-shaped lower spacers are received respectively of the plurality of spacer insertion holes. Fixing rods are respectively inserted into the fixing rod insertion hole so as to engage the plate-shaped lower spacers. A plurality of upper spacers are engaged with the upper ends of the fixing rods so as to fix the engaging pieces in spaced relation to each other.

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.

Embodiments of the present disclosure may include a modular unit for a paver unit curb installation or a black top pavement installation. The modular unit includes a main body having elongate grooves for easy lifting using the lifting tool as well as bores to connect the modular units in series with elongate connectors. The modular unit may also have elongate spikes disposed through the bottom portion of the modular unit to secure the modular units in place and to further allow the curb installation to be placed atop the bottom portion of each of the modular units.

The present invention provides a storm water pretreatment chamber. The storm water pretreatment chamber includes: a base, an inlet sidewall, a first sidewall, a second sidewall, a filter sidewall, a handle, a first locking mechanism, a second locking mechanism, a first lifting cable, and a second lifting cable. Methods of treating storm water are also provided.

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 modular overflow spout that covers a tank outlet comprising an overflow cover removably attached to a curb assembly. The overflow cover includes a canopy and a cover plate. The curb assembly comprises an outer curb having a lower curb flange that can be incorporated into the tank outlet and an upper curb flange that is positioned above the tank outlet. An inner curb is attached to the outer curb and can be incorporated into the tank outlet with the inner curb. The modularity allows the outer curb to be adjustable within the outlet so that the angle of the upper curb flange is conducive for attachment of the cover plate on the overflow cover after the curb assembly is incorporated into the tank roof.

The present invention provides a storm water pretreatment chamber. The storm water pretreatment chamber includes: a base, an inlet sidewall, a first sidewall, a second sidewall, a filter sidewall, a handle, a first locking mechanism, a second locking mechanism, a first lifting cable, and a second lifting cable. Methods of treating storm water are also provided.

A method for slipforming a concrete trench drain channel using a slipform paving machine, said drain channel having frames defining an upper opening of said channel and adapted to receive a grate; and said frames therefor.

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.

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 overall system can be cut to fit varying sized pathways, patios, driveways, and roads and features increased resistance to movement and pull-out resistance that mitigate the effects of soil displacement.
