摘要： A device for cleaning, widening and repairing of wells comprises a pipe for supplying, through a valve, compressed-air into the well and a water and air discharge pipe coaxially surrounding the air supply pipe and terminating at its upper end with a bell airtightly welded to the periphery of the air supply pipe. The water and air discharge pipe as its upper part has a first port communicating with a water discharge pipe through a valve and a second port communicating with an air discharge pipe through another valve. A head surrounds the upper portion of the water and air discharge pipe and at its upper end is airtightly welded to the periphery of the water and air discharge pipe and at its lower end terminates in a flange detachably secured to the upper end of the well-jacket. The head has a third port communicating through a valve with a pipe for discharging and similar purposes. Moreover, there are provided two annular rubber diaphragms for defining in the depth of the well the zone in which the compressed-air has to be blown for widening the well and other elements to remove deposits, stones and putrid waters. Another device is provided for removal of the pebble gravel of the well-filter and earth blocks clogging the well-filter.
