    • The present invention has an object to permit efficient and safe cleaning of a stain such as dust or molds produced on the surface of a structure including a building without damaging the cleaning site and the surrounding environment. A method of the invention comprises the steps of spraying an aggregating agent 4 comprising a cationic linear organic polymer onto the surface 2 of such structure 1 having a stain 3 produced thereon, dissociating the stain particles by use of Coulomb force f generated between the stain particles and the aggregating agent, displacing slightly the stain particles along the surface of the structure 1 to cause peeling thereof from the surface to be cleaned 2, and simultaneously, aggregating the same for cleaning. Another object of the invention is to maintain water permeability of a road (11) by easily eliminating a stain (15) adhering to the surfaces of granular aggregate particles forming a drainage-type pavement layer (12) of a road (11) without the use of various mechanical tools. Another method of the invention comprises the steps of depositing an aggregating agent (13) for soil improvement comprising a cationic organic polymer onto a drainage-type pavement layer (12) of a road (11), and eliminating the aggregated stain particles adhering to the surfaces of the granular aggregate particles constituting the drainage-type pavement layer (12) and settling in voids.

    • Apparatus for cleaning and painting roofs of buildings, comprising a self-propelling motorized mounting structure with a case (3). Case (3) houses a set of brushes (4) acting on the roof surface and spray means (21) which distribute the liquids for the treatment of this surface, and which can be attached to and removed from the structure and which are connected to a containing and feeding unit for these liquids. Similar spray means (21) for distributing a painting substance, also connected to a containing and feeding unit and which can be attached to and removed from the structure in place of the first set of spray means. In addition, the apparatus comprises a remote-control unit for the structure, for the set of brushes (4) and for controlling the various operations. The apparatus is especially designed for the reclamation of asbestos-cement roofs.
    • 用于清洁和喷涂建筑物屋顶的装置,包括具有壳体(3)的自推进电动安装结构。 壳体(3)容纳一组作用在屋顶表面上的刷子(4)和喷洒装置(21),该装置将液体分配用于处理该表面,并且可以附接到结构上并从结构上拆下 这些液体的容纳和进料单元。 用于分配涂料的类似喷雾装置(21),其也连接到容纳和进料单元,并且可以附接到结构物并从结构中移除,而不是第一组喷雾装置。 另外,该装置包括用于该组电刷的结构的遥控单元,用于控制各种操作。 该设备特别设计用于回收石棉 - 水泥屋顶。
