An underground water-storage system that includes a sump having a base and sidewalls that cooperate to define an open-topped box that defines a reservoir, a plurality of plastic water matrices each defining a void space for receiving water, and a lid. The sump and lid are formed of a reinforced geomembrane material and include welds and are prefabricated in a location remote from an installation site of the underground water-storage vault more than two days prior to installation.

An anchor assembly and related system for holding an underground tank below a ground level, including a lightweight anchor base defining a slot, and a retention mechanism that is locatable at multiple locations along the slot of the anchor base to securely maintain a strap assembly in place. The system can include the anchor assembly and the strap assembly, with the retention mechanism of the anchor assembly being movable along the slot of the anchor base to facilitate placement and adjustment of the strap assembly with respect to the anchor base.

Support structures for electrohydraulic apparatuses in particular of electrical and hydraulic apparatuses of irrigation systems are disclosed. The support structure is configured to be applied to a buriable well for housing and protecting such electrohydraulic apparatuses. On predetermined portions of the support structure a plurality of holes are formed, and are adapted for receiving a corresponding plurality of support means configured to hold, preferably in a releasable manner, one or more electrohydraulic apparatuses. Also described is a buriable well for housing and protecting electrohydraulic apparatuses comprising at least one such support structure of electrohydraulic apparatuses.

A motorcycle including a frame to which an internal combustion engine is associated, from which internal combustion engine at least one exhaust pipe of combusted gases departs, the exhaust pipe having an open terminal, the frame mounted on a front wheel and a rear wheel, a control board or unit included, for controlling torque produced by the engine and other parameters such as velocity of the vehicle and spatial position thereof with respect to the road surface. The motorcycle including a system to verify when the front wheel of the motorcycle detaches from the road surface during acceleration. The system includes a choke for partialising the section of the exhaust gases outlet area from the exhaust pipe, during partialisation. The partialisation obtained as a function of the torque produced by the engine and the position of the front wheel with respect to the road surface.

An anchoring apparatus for anchoring objects underground against upward forces includes a pair of bases, each of which comprises a container for holding weights. The object to be anchored may be positioned over the pair of bases such that the bases extend outwardly from the object. The bases are attachable to the load via mounting straps, threaded fasteners, or the like. The bases push against soil when upward forces act on the object, and the weights further operate to secure the object against the upward force.

A vent system (1) according to the present disclosure is a vent system (1) discharging a gas in an underground space (S1) communicating with a ground space (S2) via a pull-up pipe (22, 23), and includes an inert gas cylinder (12) that is disposed in the ground space (S2) and generates an inert gas, an inert gas supply pipe (13) for supplying the inert gas to the underground space (S1), and a gas concentration measurement sensor (14) that measures a concentration of the gas in the underground space (S1).

Consistent with disclosed embodiments, a stackable endcap of a chamber for holding and discharging stormwater may be provided. The stackable endcap may include an endcap body having a wall with a convex outer surface and a concave inner surface, the concave inner surface of the wall defining an interior volume of the stackable endcap; a substantially planar foot extending from a lower edge of the endcap body; and a protruding inner rim running along an inner edge of the endcap body. The stackable endcap may be configured to be stacked with at least one additional endcap such that at least one of the foot or the inner rim of the stackable endcap contacts the additional endcap while the wall of the endcap body is spaced apart from a wall of the additional endcap.
