摘要： A pumpable cement grout and method for use thereof for grouting liner pipes. The pumpable cement grout is a mixture of a hydraulic cement, water in an amount sufficient so that the water-to-cement ratio of the grout is from about 0.60 to about 1.00 by weight, and pregenerated aqueous foam in an amount sufficient to adjust the wet density of the grout to a value of from about 48 to about 72 pounds per cubic foot. The pressure at which the grout is injected into the cavity is maintained at or below a predetermined maximum pressure, so as to avoid collapsing the liner pipe.

摘要： A pumpable cement grout and method for use thereof for grouting annular cavities. The pumpable cement grout is a mixture of a hydraulic cement, water in an amount sufficient so that the water-to-cement ratio of the grout is from about 0.60 to about 1.00 by weight, and pregenerated aqueous foam in an amount sufficient to adjust the wet density of the grout to a value of from about 48 to about 72 pounds per cubic foot. The grout is pumped into an annular cavity formed intermediate a tubular external member and an internal member disposed in the tubular external member, so that the grout fills this cavity by flowing in a generally longitudinal direction therethrough. The tubular external member may be a concrete sewer pipe, and the internal member may be a plastic liner pipe. The pressure at which the grout is injected into the annular cavity is maintained at or below a predetermined maximum pressure, so as to avoid collapsing the plastic liner pipe.

摘要： A mobile train for mixing foamed cement grout within a tunnel and injecting the grout into the annular cavity between the tunnel bore and liner. Cement slurry is suppled to the train through a conduit from a remote mixing plant, and finished foam is formed by a foam generator on the train and mixed with the cement slurry to form the fooamed cement grout. The train is movable longitudinally through the tunnel so that the liner can be grouted in segments while at the same time avoiding the need to pump the foamed cement grout over excessively long distance. The train is made up of several wheeled cars which are pulled through the tunnel by a tractor.

摘要： An apparatus for continuous production of finished foam material, in which the proportions of the constituents are monitored and continuously adjustable during operation of the machine. The liquid components are metered by positive-displacement, progressive-cavity, screw-type pumps driven by variable speed motors. Rates of flow are monitored by flow meters, and the relative proportions of the constituents can be closely adjusted by varying the speeds of the pump drive motors and observing the flow meter readouts. The finished foam produced by the apparatus may be used, for example, for the preparation of foamed cement grouts or for fighting fires.

摘要： A pumpable cement grout and method for use thereof for grouting of annular cavities. There is a pumpable cement grout having portland cement, water in an amount sufficient so that the water-to-cement ratio of the grout is from about 0.6 to about 0.68 by weight, and pregenerated aqueous foam in an amount sufficient to adjust the wet density of the grout to a value of from about 55 to about 72 pounds per cubic foot. The grout is pumped into an annular cavity formed intermediate a tubular external member having a longitudinal extent and an internal member disposed in the tubular external member, so that the grout fills the cavity by flowing in a generally longitudinal direction through the tubular external member. The tubular external member may be a concrete sewer pipe, and the internal member may be a plastic liner pipe. The pressure at which the grout is injected into the annular cavity may be maintained at or below a predetermined maximum pressure, so as to avoid collapsing the plastic liner pipe.

摘要： A method and apparatus for continuous production of a quick-setting foamed cement grout, in which the individual constituents of the grout are proportionally adjustable. Finished foam and cement slurry are mixed at metered rates to form a foamed cement grout which is pumped to a wye connection proximate a remote injection site. Sodium silicate solution is added at the wye connection at a metered rate, using a second metering pump. The sodium silicate solution mixes with the foamed cement grout to greatly accelerate the setting time thereof, and compressed air may also be added to accelerate the passage of the material through the injection hose and nozzle. The quick-setting material is particularly suited for use with a tunnel boring machine (TBM), to grout the annular cavity between the tunnel bore and the segmented liner which is installed therein.

摘要： An apparatus and method for the continuous generation and placement of a foamed cement grout. The assembly is mounted on a fixed or mobile frame. There is a continuous foam generator, and this supplies finished foam to an intake port of a screw-type, positive-displacement pump. Cement slurry is also supplied to the intake portion of the pump, and this is mixed with the foam in the body of the pump and discharged from this through a conduit to the injection site on a continuous basis. The ratios of foam and slurry can be adjusted on a continuous basis to compensate for variations in grout quality which are observed at the injection site. The assembly is also provided with an onboard power generator and a water pump for flushing the grout out of the injection lines.

摘要： An apparatus for high capacity production of high-fluidity, colloidally mixed cement slurry. Water and cement dust are combined at metered rates by a premixing assembly which discharges into a mixing tub. The high-speed, high-shear pump recirculates the material through the tub to produce the colloidally-mixed slurry. The high-fluidity slurry may be provided to a second pump, preferably of the positive-displacement, progressive-cavity, rotor-stator type, for supplying the slurry at a metered rate. Finished foam material may also be provided to the slurry metering pump at the metered rate, so the materials are mixed to form a foamed cement grout in which the weight and quality of the material is precisely adjustable.
