る付着物の除去，清掃方法。1. A method of removing and cleaning deposits, which removes and cleans deposits such as sheet piles and H-shaped steel, construction iron plates and liner plates, earth and sand adhering to civil engineering members, paints, coagulants, etc. And, the deposits attached to the building and civil engineering members are mechanically scraped off as a pre-stage of removal and cleaning, that is, after so-called rough dropping, a plurality of jets are arranged around the architectural and civil engineering members. It is decided to remove and clean by dropping with a mixed low pressure water flow of water and compressed air jetted from a nozzle, and the jetted water to the building and civil engineering members is in a state where the dropped deposits are mixed. It is assumed that the collected deposits are sent to the respective injection nozzles and are circulated again, and that the deposits mixed in the circulation are separated. Circulating jet water Along with sending to the injection nozzle together with discharging the rest to the outside, on the other hand, the earth and sand sent to the injection nozzle together with the circulating injection water, by injecting the mixed low pressure water flow to the building, civil engineering members by , Improving the removal efficiency of adhered substances by the earth and sand particles, and by the low-pressure injection mixed flow that mixes air and water with the recovered injection water and earth and sand from each of the injection nozzles, for the construction and civil engineering A method for removing and cleaning deposits on construction and civil engineering members, characterized by reliably removing and cleaning deposits on members.

材における付着物の除去，清掃装置。2. An apparatus for removing and cleaning deposits, which removes and cleans deposits such as earth and sand, mortar, and coagulants adhering to construction for sheet piles and H-section steel, iron plate and liner plates, and civil engineering members. And a plurality of transportation line parts for moving the building and civil engineering members at a predetermined speed, and a plurality of transportation line parts surrounding the buildings and civil engineering members are arranged in the transportation line part, and a low mixing ratio of water and compressed air is provided. An injection nozzle that injects a flow of pressure water to a building or civil engineering member, a cover portion that is provided so as to cover the periphery of each of the injection nozzles, and a front position of the transport line portion with respect to the cover portion. Along with the rough removal part that mechanically scrapes off the deposits on the building and civil engineering members, the spray water from each of the spray nozzles and the deposited deposits are sucked and collected, and the collected deposits are also collected. The adhering matter is separated from the jetted water mixed with, and a part of the earth and sand in the separated adhering matter and the recovered jetted water are sent to each injection nozzle for circulation, and the remaining adhering matter is discharged to the outside. A collecting / separating unit for removing building deposits and cleaning equipment for construction and civil engineering members.
