A manhole base assembly and a method for making the same employ a non-cylindrical, low-volume concrete base that is fully lined to protect the concrete against chemical and physical attack while in service. This lined concrete manhole base assembly may be readily produced using a modular manhole form assembly which can be configured for a wide variety of geometrical configurations compatible with, e.g., varying pipe angles, elevations and sizes. The form assembly is configurable to provide any desired angle and elevation for the pipe apertures to interface with various underground systems, and can be formed on-site to facilitate compatibility with existing structures. The assembly provides for flexible, modular construction of a wide variety of lined manhole base assemblies at minimal cost, reduced concrete consumption and reduced operational complexity. The modular nature of the production form assembly also facilitates reduced inventory requirements when various manhole base assembly geometries are needed.

A vertical manhole apparatus for use in a waste facility to provide access to one or more leachate collection pipe access points. The vertical manhole is stabilized using stabilizing features extending out from a vertical pipe of the vertical manhole apparatus.

A permanent on-site manhole casting system consisting of three basic components (a top, a base and a main barrel) which comprise an outer barrel, an inner barrel, a plurality of tie strips used to connect said outer and inner barrels, a coupling mechanism which connects the three basic components, and a concrete mixture that is poured into the space between the outer and inner barrels and allowed to set and cure is provided. The on-site manhole-casting system is designed to create a single manhole unit which is chemically resistant and configurable to numerous manhole and utility system needs.

An apparatus and method is provided for repairing an underground structure such as a pipe or manhole. The apparatus includes a liner assembly made of resin absorbent material. Some embodiments may further include a bladder assembly to help position the liner and press the liner against the walls of the underground structure. A sealing member is positioned in the underground structure. In some embodiments the sealing member is a separate member made from a compressible material, an absorbent material, or a hydrophilic or hydrophobic material. In other embodiments the sealing member is a portion of the liner assembly. The sealing member includes one or more channels adapted to receive a semi-liquid such as a hydrophilic or hydrophobic paste or grout. The semi-liquid is capable of swelling in response to being exposed to another liquid, such as water, and forms a seal between the liner assembly and the host pipe/manhole.

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 partializing the section of the exhaust gases outlet area from the exhaust pipe, during partialization. The partialization obtained as a function of the torque produced by the engine and the position of the front wheel with respect to the road surface.
