することもしばしば見受けられるようになる。Prior Art: As is well known, concrete structures deteriorate after several years or more after construction.
Cracks occur on walls, etc., causing water to flood. In particular, finishing mortar and exterior tiles on the exterior walls of buildings and other buildings often peel off, creating a dangerous situation.

れている。 Since this condition is dangerous, in addition to peeling it off and putting on a new exterior, we have also adopted methods for partial repairs such as injecting grout into the cracked and peeled areas to fill in the gaps and at the same time bonding the loose parts. has been done. Various methods have already been proposed as this grout injection method. For example, as shown in Japanese Patent Application Laid-Open No. 60-261868, which is a prior invention, anchor holes are drilled at required locations to attach a drug injector,
A construction method has been adopted that allows rational reinforcement by burying an anchor plug in this area and attaching a syringe to automatically pressurize the chemical solution into the crack or peeling gap.

る。 However, although it is possible to drill an anchor hole to attach a chemical injector to a wall surface (the term "wall surface" includes not only the outside and inside surfaces of a building but also the ceiling surface), conventionally it was possible to drill an anchor hole directly into the wall surface using concrete. Since the holes are drilled using a drilling drill, chips are scattered around, which is inconvenient not only for the worker but also for the work area where dust is to be avoided. Also,
If you try to improve work efficiency by injecting water during drilling, not only dust but also sewage will scatter and pollute the surrounding area, so you must be very careful when using it in places where dirt is a problem, whether indoors or outdoors. It's unreasonable.

The dust removal chamber connected to the pump,
Using a small portable dust collector with an end-face sealing mechanism, this dust collector is held by adsorption on the wall surface for drilling, and a drill is used to inject water into the dust suction chamber from the shaft center while anchor holes etc. The concrete chips and sludge generated during drilling were removed by suction, allowing drilling to be carried out in a closed state.

る。Function: According to the construction method of the present invention, when drilling a hole in preparation for injecting adhesive at the required location during repair work for lifting of the exterior or cracking on the wall surface of a concrete building, the target location of the hole is first determined. If you position the dust suction chamber of the dust collector and place the suction/exclusion box against the wall so that the drill can come into contact with it, the suction/exclusion box can be removed by connecting it to a vacuum pump (suction pump) and activating it in advance. is adsorbed to the wall. Therefore, if the drill is driven and drilled while supplying water from the insertion hole to the wall drilling position, the chips and the injected water will pass from the dust suction chamber to the dust exhaust chamber, be quickly guided to the separator by the conduit, and collect the dust. Dust generated in the area surrounded by the tool is disposed of without leaking to the outside. In particular, in order to enhance the anchoring effect, when a hole is drilled into the frame beyond the space created in the raised part of the wall exterior, all concrete chips and drilling contaminated water remaining in the wall space are sucked out, preventing spillage to the outside. Moreover, the holes can be drilled cleanly without filling the voids, and the adhesive injection treatment method can be carried out effectively. Once the suction force inside the box is removed, it can be easily removed from the wall and moved to the next location.

性が高くなるように形成してある。 What is shown in FIG. 1 is a specific example of a portable dust collector 1 used in the construction method of the present invention. Reference numeral 2 denotes the main body, which is a flat cylindrical one-side open type box made of synthetic resin. Reference numeral 3 denotes a dust suction chamber, which is formed inside the main body 2 with a cylindrical partition wall 4 eccentrically attached thereto. This dust suction chamber 3 and a dust exhaust chamber 5 formed inside the main body 2 communicate with each other through a large number of through holes 6 formed in a partition wall 4 surrounding the dust suction chamber 3. The dust removal chamber 5 has a conduit 15 connected to a suction pump.
A mounting tube 7 is attached. In order to shut off the dust suction chamber 3 and the dust exhaust chamber 5, seal rings 8 and 8' are independently fixed to the open edges, respectively. In particular, the seal ring 8 attached to the end edge 2' of the main body 2 is formed so that the outer peripheral edge 8'' is thinned so as to be in close contact with the wall surface.

れる。 For example, when using the dust collector 1 with such a configuration to repair a raised exterior wall of a concrete building A, depending on the site situation, as shown in FIG. When injecting the adhesive agent into B, set the range of its lifting,
Drill the hole in the position that is considered optimal. As a preparatory means, the dust collector 1 is brought into contact with the dust collector 1 so that the dust suction chamber 3 faces the predetermined position. If the suction pump is operated in this state, the suction force acting on the dust evacuation chamber 5 will create a negative pressure, so that the main body 2 will come into close contact with the wall surface A'. Therefore, the water supply unit 21 is installed in the drill 20 with a water injection hole.
is attached to the output shaft of a drive motor (not shown) through the drill insertion hole 10 of the dust collector 1 to the target wall surface.
Press the drill 20 onto A' to make a hole. At this time, if an appropriate amount of water is spouted from the tip of the drill through the hose 22 connected to the water supply unit 21 to the drill 20 while drilling, the concrete chips and cutting waste water generated by this drilling will be removed from the dust exhaust chamber under negative pressure. 5, the dust is sucked from the suction chamber 3 through each through hole 6, and is quickly drawn into the dust collector 1. At the same time, a separator (not shown) provided in the conduit 15 to the suction pump P ) where chips and muddy water are separated and collected.

穿孔を要せず、目的深さに穿削できる。 By performing drilling work while collecting dust in this way, no matter where you drill holes in concrete walls, there will be no scattering of dust or water droplets to the surrounding area.
Therefore, the holes can be drilled without contaminating the work area or walls. If the hole is further drilled to the frame and the hole C straddles the floating gap B, chips will naturally enter the gap B, but all such chips will be sucked out and remain in the gap. It is possible to drill to the desired depth without the need for excessive drilling.
