Abstract
An apparatus and method is provided for lining the wall of a manhole. The apparatus may include a liner assembly. The liner assembly includes a bladder, a liner holding device, and a liner. The bladder comprises a first end positioned near an opening of the manhole, and a bladder body positioned in the manhole. The liner holding device is positioned at least partially above the opening of the manhole. The liner includes a first end operably connected to the holding device, and a liner body positioned at least partially surrounding the bladder in the manhole. The liner holding device is adapted to feed a portion of the liner body into the manhole during expansion of the liner body.
Claims22
A liner assembly for repairing a wall of a manhole, comprising:
- a bladder having a first end positioned near an opening of the manhole and a bladder body positioned in the manhole;
- a liner holding device positioned at least partially above the opening of the manhole;
- and
- a liner having a first end operably connected to the holding device and a liner body positioned at least partially surrounding the bladder in the manhole.
A method of lining a manhole from a bottom of the manhole upwardly, comprising:
- taking a manhole liner capable of stretching circumferentially, the liner comprising a first end, an opposite second end, and a liner body there between;
- applying a resinous material capable of curing and hardening to the liner;
- positioning the liner in the manhole;
- inserting a bladder into the liner;
- expanding the bladder with a fluid to press the liner against a wall of the manhole, the bladder expanding at the bottom of the manhole first and expanding circumferentially and upwardly towards a manhole opening;
- lowering excess liner body into the manhole;
- and
- allowing the resinous material to cure and harden.
A method of lining a manhole from a bottom of the manhole upwardly, comprising:
- taking a manhole liner having a resin absorbent layer and a fluid-impervious layer, the liner having a liner body extending between a first end and an opposite second end and being capable of stretching circumferentially;
- applying a resinous material capable of curing and hardening to the liner;
- positioning the liner in the manhole;
- expanding the liner with a fluid to press the liner against a wall of the manhole, the liner expanding at the bottom of the manhole first and expanding circumferentially and upwardly towards a manhole opening;
- lowering the excess portion of the liner body into the manhole;
- and
- allowing the resinous material to cure and harden.
