摘要： A top concrete section for a manhole assembly is cast with a plurality of bolt slot inserts each insert having a substantially inverted T-shaped hollow interior for slideably receiving a nut which may be moved to any desired position along the base of the insert for threadedly engaging a threaded rod employed to rigidly secure a cast iron cover frame to the top section.The method for casting a manhole top section comprises the steps of releasably mounting each insert within the mould assembly by means of a retaining slide which itself is slideably received within a pair of holding brackets provided on each of the inner and outer mould members, the insert being substantially fully closed on all sides thereof and having a top surface formed of a thin web which is easily fractured or cut away after the top manhole section is cast. The fully enclosed insert prevents any concrete from entering into the interior thereof.The nut may be moved along the length of the insert base in order to bring it into alignment with bolt hole centers in the cast iron frame.

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 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： A gasket formed of an extruded elastomeric material which is joined at its ends to form a closed loop. The gasket has a cross-section defined by a T-shaped anchoring flange integrally joined to a substantially pear-shaped portion which tapers in the radially inward direction. An integral flange extends diagonally away from the radial direction and serves to significantly enhance the water-tight seal provided by the resilient gasket, as well as significantly increasing the range of pipe diameters capable of being accommodated by the gasket. Disc-shaped or cylindrical-shaped inserts insertable into cavities at angular intervals about the wall of the opening engage the gasket to center the pipe and to aid in reducing shearing forces.

摘要： In a method for forming inverts in a manhole base using a 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 is in precise alignment with associated sidewall openings. The apparatus for the two pour technique 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.. In one arrangement, 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 clamp, assure precise alignment between the channel-shaped projections forming the invert and prevent flotation of the invert form during casting.

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.
