摘要： A resilient gasket having an outer flange positioned within a manhole opening and held by a compression band. The gasket has a central opening with an enlarged beaded periphery to encircle a pipe. A tapered intermediate section is joined to the outer flange and the beaded periphery. The intermediate section folds after insertion and clamping in an opening to form diagonally aligned annular portions defining a V-shaped yieldable gasket to maintain a watertight seal between opening and pipe, even when misaligned. A strap encircling the gasket next to the beaded periphery enhances the watertight seal between gasket and pipe. The clamping band has free ends which cooperate with projections of a piston cylinder assembly. The clamping band is formed of material impervious to the surrounding environment. The expansion assembly includes the aforementioned piston cylinder assembly which cooperates with an hydraulic jack and is positioned with its projections against the free ends of the clamping band to expand the clamping band into a locked position against the gasket flange and to apply a force directly upon the clamping band to insure proper positioning and locking of the clamping band. The hydraulic jack may also include a swingable member having a free end which moves along a curved path to follow the movement of the clamping band as it expands. The initial configuration of the gasket expedites the insertion, expansion and locking of the clamping band. A cooperating groove receives a projection, said groove and projection being adjacent at oppostie ends of the clamping band to prevent relative axial movement of the clamping band ends as it is expanded.

摘要： A hollow, flexible, bendable, cylindrical-shaped, hat-like sleeve is water-tightly joined with the upper end of the riser section of a manhole structure. The free end of the sleeve is trimmed so that its upper edge fits beneath the shoulder of the frame supporting the manhole cover to prevent subsurface water from entering into the manhole interior through the regions between the manhole cover supporting frame and the top of the riser section, which is usually fitted with adjustment rings to bring the manhole cover frame up to grade. The sleeve is easily cut to any height to accommodate either a greater or lesser number of height adjustment rings. The sleeve flange is cast into the riser section. The sleeve may be folded into itself to significantly lower its profile to expedite handling, transportation and assembly. A plastic clamping band may be placed into the interior of the sleeve to water-tightly join the upper end of the sleeve to the manhole cover support frame.

摘要： A resilient gasket having an outer annular flange positioned within a manhole opening and maintained thereagainst under compression by means of a compression band. The gasket is provided with a central opening defined by an enlarged beaded periphery having an elasticity adapted to tightly encircle the outer periphery of the pipe. A folded intermediate section is arranged between and integrally joined to the outer flange and the beaded inner periphery, the intermediate section is comprised of first and second diagonally aligned annular portions integrally joined along a fold to define a V-shape which imparts a yieldability enabling the gasket to maintain a watertight seal between the manhole opening and the pipe, even in the presence of a significant misalignment therebetween. A strap is positioned about the intermediate section of the gasket adjacent the inner beaded periphery to enhance the watertight seal between the gasket and the pipe. The compression band may be provided with pairs of substantially V-shaped slots which enable the band to assume a curvature in a direction transverse to the curved periphery in order to conform to the curvature of the manhole opening. The clamping band is formed of a material which is impervious to the surrounding environment and has a gap and a segment hingedly connected to the main body thereof for placement in said gap and against the interior surface of the gasket to lock the compression band in position and maintain the gasket flange under compression. An expansion assembly includes an expansion ring which cooperates with a hydraulic jack and is positioned against the compression band to expand the compression band into position against the gasket flange and to apply a force uniformly around the compression band to insure proper positioning and locking of the clamping band.

摘要： A system of modular precast encasement sections is provided to protect the outside drop of a manhole structure from damage due to weak ground support and to prevent leakage from said outside drop. Said precast encasement sections are stacked on top of a drop manhole base and on top of each other to a height sufficient to surround and support the outside drop tube. The stack of encasement sections is then capped off with a solid collar which has a circular opening of a diameter sufficient to receive the outside drop tube. This circular opening widens to form a shoulder which is adapted to receive and support thereon the lower most opening of a T-coupler for joining a supply line to the drop tube. The precast encasement sections, the solid collar, and the face of the manhole base which is to receive the stack of encasement sections are each provided with grooves on their upper faces and the solid collar and encasement sections are provided with coaligned projections along their lower faces. These grooves and projections serve to automatically align the sections with the manhole base, with the solid collar and with each other when the sections are assembled on site.

摘要： Apparatus for forming inverts in a manhole base using a single pour or double pour technique. In the single pour technique, the invert is formed simultaneously with the formation of the manhole base using a mold member having a channel-shaped projection defining the invert. Alignment members simply, and precisely, align the mold member having the channel-shaped projection with the members forming the base member sidewall openings to form a manhole base having an invert in precise alignment with associated sidewall openings. In the two pour technique, the manhole base is initially formed. Thereafter, channel invert forms are aligned with sidewall openings by alignment members arranged within the manhole openings to assure precise alignment therebetween, wherein the invert formed within the manhole base by pouring the casting material into the base member forms an invert which is in precise alignment with associated sidewall openings. The apparatus for both single and double pour techniques incorporates at least one adjustably positionable channel-forming assembly for forming an invert communicating between associated sidewall openings each having a central axis and whose intersecting central axes define an angle different from 180.degree.. Flexible members join the ends of the invert form. Alignment members on the inverts and a flexible internal member, either alone, or in cooperation with a joining bar and a clamp, assure precise alignment between the channel-shaped projections forming the invert and prevent flotation of the invert form during formation. A method and apparatus is disclosed for producing resilient, flexible inverts.
