    摘要: 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.

    摘要: An apparatus and method is provided for lining the wall of a manhole. The apparatus may include a liner assembly, which includes an expansion device, an auxiliary bladder, a primary bladder, and a liner. The auxiliary bladder is first inflated near the top of the manhole. Next the primary bladder may be expanded to press the liner against the wall of the manhole. The liner, being impregnated with a resinous material, is pressed against the wall until the resinous material cures and hardens. The expansion device, auxiliary bladder, and primary bladder are then removed from the manhole. The result is a repaired manhole wall.

    摘要: A method for renovating a sewer manhole includes: a. pulling an inflatable film sleeve onto a mold corresponding to the sewer manhole profile; b. wrapping and/or laying an extensible textile strip of the film sleeve onto the mold, a non-extensible high-tensile-strength longitudinal strip also being laid in an axial direction between the strips; c. attaching a protective sheath enclosing the liner manufactured in this manner; d. pulling the liner off the mold that has been reduced in a radial direction; e. inserting the liner into a sewer manhole to be renovated, and introducing a pressure-tight bag into the inner film sleeve of the liner; f. sealing the liner at the upper end and inflating until it abuts against the manhole wall; g. curing the resin-impregnated liner. A variable mold, which is assembled from modules of different shapes and sizes corresponding to the sewer manhole, serves for manufacture of the liner.

    摘要: A method of repairing and renewing a manhole chimney utilizes a circumferentially stretchable liner sleeve which is inserted into the manhole and pressed by an inflatable bladder into engagement with the walls of the manhole chimney. The sleeve is coated with an uncured resin, which is allowed to cure as the sleeve is pressed against the chimney walls, thereby attaching the sleeve to the walls of the manhole chimney. The stretchable sleeve eliminates air spaces between the sleeve and the chimney walls, and precludes formation of undesirable folds in the sleeve. The sleeve stretches circumferentially up to 150% of its unstretched diameter, while having a substantially unstretchable length.

    摘要: The present invention comprises a method and means for repairing the wall of a manhole wherein a material capable of curing and hardening is adhered to the wall. An expandable bladder engages the curable and hardenable material and presses against and smoothes the material. The bladder may be chemically bonded to the curable and hardenable material or it may be mechanically bonded.

    摘要: The disclosure is for an underground structure liner based upon an inflatable liner structure. An acid resistant layer is the innermost layer of an inflatable liner, and the liner is coated with epoxy resin on its outermost surface, the surface which contacts the existing walls of the underground structure. The outermost coated surface of the liner is constructed with a fibrous fleece layer for better retention of the epoxy and better adhesion of the epoxy to the walls of the underground structure. An added feature of the liner is a structure which also seals the liner to pipes entering the underground structure.

    摘要: There is described a method and a liner for in situ renovation of a sewer manhole, e.g., a transition well, where inside the well there is inserted a prefabricated liner in the shape of a glass fiber reinforced stocking of thermosetting polyester or epoxy formed by winding, weaving or braiding externally of a unilaterally suspended mold with a diameter allowing the mold to be lowered through a manhole curb or cone, the rubber coating consisting of a detachable rubber bag that is fastened to a flange to be displaced externally on the mold, the polyester or epoxy liner being wound, woven or braided in such a way that the length/diameter ratio of the liner may subsequently be changed by changing the length/diameter ratio of the liner as the polyester or epoxy impregnated glass fibers are connected with the flange by the winding, weaving or braiding.
