本発明は、耐火構造などの建築物の壁面表層部に設けら
れた石綿を含む構築壁の除去方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for removing constructed walls containing asbestos provided on the surface layer of walls of buildings such as fireproof structures.
建築物の内壁、天井壁などの表層部に、石綿を含む構築
壁が断熱用として最近まで多用されて来た。ところが、
近年石綿が人体に有害であることが明らかとなり、石綿

になった。しかし、この場合に作業者などが石綿を吸引
したり、皮膚に付着したりすると健康に障害を与えるの
で、その対策が必要となる。Until recently, constructed walls containing asbestos have been widely used for insulation purposes in the surface layers of buildings, such as interior walls and ceiling walls. However,
In recent years, it has become clear that asbestos is harmful to the human body, and it has become common practice to dismantle and remove constructed walls containing asbestos. However, in this case, if asbestos is inhaled by workers or comes into contact with their skin, it can cause health problems, so countermeasures are needed.
そこで、特開昭８２−１７８８５９号公報に示されてい

ている。Therefore, as shown in Japanese Patent Application Laid-Open No. 82-178859, a nonionic surfactant mainly composed of octinol derivatives is injected or sprayed as a lubricant into a constructed wall containing asbestos, and the constructed wall is A method has been proposed in which the material is moistened and removed in this state. In this method, a worker manually uses a tool such as a scraper to remove the asbestos-containing construction wall from the building frame wall so as to maintain its original shape.

ものの回収を手作業で行っているので、回収作業も面倒
である上に、この作業時にも作業者などの人体に石綿が
付着する恐れがあるという問題点があった。However, in the conventional method for removing constructed walls containing asbestos, as described above, even after removing this with a tool such as a scraper, some of the constructed walls containing asbestos remain on the building frame wall, so the remaining material must be removed. The problem is that asbestos must be removed by scrubbing with a brush, which takes a long time for the worker, and there is a risk that asbestos may adhere to the skin of the worker even if he or she is wearing protective clothing during long hours of work. In addition, after peeling off the asbestos-containing construction wall, it spreads over a wide area and falls onto the floor, etc., and the fallen material must be collected manually, which makes the collection work tedious and also requires a lot of work during this work. There was a problem in that asbestos could adhere to the human body of people such as people.

際に作業者などの人体に石綿が付着する恐れもない。The method for removing a constructed wall containing asbestos according to the present invention involves squirting pressurized water onto the constructed wall from a nozzle surrounded by the hood while pressing the open end of the hood of the collection head against the constructed wall. By peeling off part of the wall, by adjusting the pressure of the pressurized water appropriately, the constructed wall can be dismantled to an appropriate size without using scrapers or brushes, and the inner wall of the building frame can be removed. Since it can be removed from the ceiling wall and no built-up wall remains on these walls, the built-up wall can be removed in a short time, and the built-up wall can be removed with a scraper or the remaining built-up wall can be rubbed with a wire brush. In addition, the construction wall that was removed using pressure water and the water that spouted out are contained within the hood, and almost no flow out of the hood, and the construction wall that was removed and The water after gushing out can be collected in a collection tank by vacuuming, making it easy and quick to recover the peeled off construction wall. There is no risk of asbestos adhering to the human body.

By injecting from the turbo nozzle (3) by driving 5), the construction wall is made easier to peel off. In this case, the wetting agent is placed in a water tank (8), and a vacuum suction device is also used.
(11) should not be activated. Next, apply water or water containing a wetting agent or cleaning agent to the required amount while pressing the open end of the hood (2) of the collection head (1) against the construction wall. The part located inside the hood (2) of the construction wall is disassembled into an appropriate size using pressure water and peeled off from the inner wall of the building frame. In this case, the driving source (8) water pump (
5), the vacuum generation pump (9) is activated and pressurized water is ejected from the nozzle (10a) in the venturi (10), thereby drawing a vacuum from the safety tank (15) and recovery tank (13) and stripping. The water that has been spouted out from the construction wall passes through the hood (3), the cylindrical part (la) of the collection head (1), and the suction hose (12), and then flows into the collection tank (
13) After sucking into the collection bag (14) inside and separating the water,
In addition, safety tank (15), venturi (1G)
The dismantled construction wall is returned to the water tank (6) through the water tank (6), and the dismantled construction wall is stored in the collection bag (14). In this state, the entire construction wall is dismantled and removed by a worker moving appropriately while holding the collection head (1). When the water in the water tank (8) decreases, this is detected by the water level gauge (18), the water supply valve (20) is opened, and the water supply pipe (21) that has been connected to a water pipe etc. is opened. ) into the water tank (8), and when a predetermined water level is reached, the water supply is stopped intermittently, and the vacuum pressure regulating valve (1e) and water pressure regulating valve (17) are adjusted as appropriate. Adjust the vacuum suction power and water supply pressure.

In 3), the pressure inside the safety tank (15) is detected, and if an abnormality in the pressure occurs, the drive source (8) is stopped. Furthermore, by rotating the turbo nozzle (3) around the axis as necessary, the direction of the pressure water spouted from the nozzle (3) can be changed. When the dismantled material is filled, the device is stopped, the lid of the collection tank (13) is opened, the dismantled construction wall material stored in the collection bag (14) is taken out, and a new collection bag (14) is inserted. Installed inside the recovery tank (13).

In addition, in the present invention, the hood of the collection head is preferably flexible, and even if the flexible water supply hose and suction hose are stored wrapped around one hose drum, they can be stored in another hose drum. Alternatively, the hose drum may be omitted.Furthermore, in the present invention, a synthetic resin sheet or the like is laid on the floor of the room where the construction wall is to be removed, and the worker wears protective clothing. Wearing is similar to performing the conventional method.

体に石綿が付着する恐れがなく、健康管理上好ましい。As explained above, according to the method of the present invention, the open end of the hood of the recovery head is pressed against the constructed wall containing asbestos, and pressurized water is applied to the constructed wall from the nozzle surrounded by the hood. Since it is made to eject and peel off a part of this, the constructed wall can be dismantled and peeled off, and the constructed wall can be easily removed in a short time without leaving any residue behind, requiring less labor for one worker. can do. Also,
The construction wall that has been peeled off with pressure water and the water that has spouted out are stored inside the hood without leaking out of the hood, and the water that has spouted off the construction wall that has been peeled off can be collected in the recovery tank by vacuuming, so this recovery method is effective. can be easily done in a short period of time, and there is no risk of asbestos adhering to the human body of workers and the like during the work of peeling off the constructed wall and collecting the peeled off materials, which is favorable from the viewpoint of health management.

するという効果がある。Further, according to the removal device of the present invention, all components such as the water pump, water tank, recovery tank, and vacuum suction device are mounted on a car and transported to the site, and the collection head is attached to the vacuum suction device, and the nozzle is attached to the water pump. Since it is connected with a flexible hose, one worker can easily approach the constructed wall containing asbestos to be removed by holding the collection head, making it easy to remove the constructed wall and work before and after that. This method has the advantage that it is suitable for removing constructed walls containing asbestos by the method of the present invention described above.
