Abstract: 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.

Abstract: A manhole base assembly and a method for making the same, in which a non-cylindrical, low-volume concrete base 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 using existing, standard sets of form assembly materials, and may also be used in conjunction with industry-standard cylindrical casting jackets for compatibility with existing casting operations. The resulting system provides for flexible 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.

Abstract: An apparatus for separating and lifting a manhole cover from a cover mounting ring without disturbing the mounting ring includes a body, a lever arm and lifting arm pivotally connected to the body with the outer end of the lifting arm extending outwardly from the first end of the body, an preferably hydraulic actuator for raising and lowering the outer end of the lifting arm, and a ring engagement plate extending outwardly from the first end of the body below the lifting arm, to be received over the cover mounting ring. The apparatus may be constructed by modifying a conventional hydraulic floor jack. Upon activation of the hydraulic actuator lifting force is imposed between the cover and the cover mounting ring to separate and lift the cover without disturbing the mounting ring.

Abstract: A sealing assembly for sealing a manhole against entering liquid includes a guide ring with an adjustable diameter and set screws for pressing against interior walls of the manhole when the diameter of the guide ring is set to approximately the diameter of the manhole walls, a sealing ring for resting on top of the guide ring and an expandable ring disposed at the inner periphery of the sealing ring and expanded to compress the sealing ring against the walls of the manhole to provide a liquid-tight seal. The sealing assembly also includes a lid positioned on top of the sealing ring. The lid preferably has a removable portion to allow access through the lid without taking the lid off of the sealing ring and without destroying the integrity of the caulking. In a method of sealing a manhole, there is a step of fixing a guide ring to the interior walls of the manhole, placing the sealing ring on top of the guide ring, placing an expandable ring at the interior of the sealing ring and expanding the expandable ring so that it presses against the sealing ring to compress the sealing ring against the walls of the manhole to provide a liquid-tight seal, and placing a lid on top of the sealing ring. A simplified version of the sealing assembly and method involves using the weight of the manhole cover to compress a gasket against the interior walls of the manhole.

Abstract: An in-floor access pit unit for use in a floor having a flooring of a predetermined thickness thereon. The access pit basically comprises a rigid liner, a lower frame, an intermediate frame, a cover assembly, and a height adjusting mechanism. The cover assembly comprises an upper frame in which a cover plate is mounted to provide a recess for receipt of a piece of the same flooring material as on the floor in which the access pit is located. The cover assembly is mounted in the intermediate frame by the height adjusting mechanism. That mechanism comprises plural bolts and nuts for adjusting the height of the intermediate frame and the cover member so that the piece of flooring within the cover assembly is flush with the surrounding flooring. The intermediate frame includes a downwardly depending flange which is disposed closely adjacent a sidewall of the lower frame to prevent the ingress of material therebetween. A sealing gasket is provided between the cover assembly and the intermediate frame to prevent the egress of gases or fumes from the access pit.

Abstract: A manhole having a splayed rib ring extending from under a lid, an annular supporter having a beveled underside extending around the opening of a ring seat, and an insulation hood attached to an inner side of the splayed rib ring. Both the splayed rib ring and the annular supporter may or may not be concentric with the lid or the ring seat, respectively. Vibration and possible bouncing of the lid is reduced or offset because the splayed rib ring of the lid is retained by the bevelled underside of the annular supporter. A half round groove formed around an outer bottom periphery of the lid accommodates a rubber gasket which prevents the lid from directly contacting the annular supporter, and absorbs and relieves vibration of the lid to reduce the possible noise. The insulation hood completely prevents any worn cables under the manhole from directly contacting the lid and therefore, prevents any possible leakage via the lid that might endanger vehicles and walkers passing by the manhole.
