The present invention relates generally to cleaning waste collection systems such as but not limited to sewers, sumps, wet wells, collection tanks, digesters, clarifiers, classifiers, etc. and in particular to cleaning and removal of solid and liquid materials therefrom. In another embodiment, the present invention relates to an improved slurry hose and/or pipe for use in connection with cleaning waste collection systems such as but not limited to sewers, sumps, wet wells, collection tanks, digesters, clarifiers, classifiers, etc. and in particular to cleaning and removal of solid and liquid materials therefrom.

A system includes an inspection robot having an input sensor comprising a laser profiler and a plurality of wheels structured to engage a curved portion of an inspection surface, wherein the laser profiler is configured to provide laser profiler data of the inspection surface; a controller, comprising: a profiler data circuit structured to interpret the laser profiler data; determine a feature of interest is present at a location of the inspection surface in response to the laser profiler data; and wherein the feature of interest comprises a shape description of the inspection surface at the location of the feature of interest.

Pipe inspection systems including a push-cable, jetter, and camera assembly are disclosed. A jetter nozzle may be configured to spin and/or propel the camera head within a pipe or other cavity. A cutter line may be attached to the camera head to clean obstructions. A sonde may be coupled to a camera head to generate magnetic field signals for use with a buried utility locator to locate a pipe or other cavity into which the camera head is deployed.

Transit Cleaning Unit is able to clean the walls, overhead, insulators third rail covers and flooring of the subway systems in a minimum amount of time.

It provides an effective means of providing a clean environment for the benefit of the customers.

A sewer cleaning apparatus which has a hollow cylindrical body propelled by a plurality of water jets with a clam shell opening on the front of the apparatus operated by a plurality of piston assemblies that are attached to the sides of the cylindrical body. The apparatus is propelled by high pressure water ejected from the apparatus in a rearward direction. The high pressure water operates the piston assembly opening the clam shell and provides forward thrust for the apparatus allowing the hollow bucket type object to trap solids inside apparatus.

A system includes an inspection robot for performing an inspection on an inspection surface with an inspection robot, the apparatus comprising a position definition circuit structured to determine an inspection robot position on the inspection surface; a data positioning circuit structured to interpret inspection data, and to correlate the inspection data to the inspection robot position on the inspection surface; and wherein the data positioning circuit is further structured to determine position informed inspection data in response to the correlating of the inspection data with the inspection robot position, wherein the position informed inspection data comprises absolute position data.

A method of prepping a cylindrical inner surface of a bore using a high-frequency forced pulsed waterjet apparatus entails generating a pressurized waterjet using a high-pressure water pump, generating a high-frequency signal using a high-frequency signal generator, applying the high-frequency signal to a transducer having a microtip to cause the microtip to vibrate to thereby generate the high-frequency forced pulsed waterjet, and rotating the rotatable ultrasonic nozzle inside the bore to prep the inner cylindrical surface of the bore using the high-frequency forced pulsed waterjets exiting from the angled exit orifices of the rotatable ultrasonic nozzle.

The present invention relates to an intervention drive pig comprising an umbilical. In this scenario, the present invention provides an intervention drive pig comprising an umbilical, wherein the umbilical (6) is manufactured from a low-density material, wherein the umbilical (6) comprises an external covering of material having a low coefficient of friction.
