に細心の注意を払わねばならず、不合理である。However, the entire wall of the chemical injector (this wall is a collective term that includes not only the outside and inside surfaces of the building, but also the ceiling surface, etc.)
Conventionally, holes for anchors can be drilled directly into the wall using a concrete drilling drill, which scatters chips and damages not only the worker but also the work area. This was often inconvenient in places where dust was to be avoided. However, 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 be very careful when using it in places where dirt is a problem, whether indoors or outdoors. It is inevitable and irrational.

In addition, the above-mentioned disadvantages also occur.Purpose of the Invention: The present invention solves this problem of drill collapse, and makes it possible to cool the drill during drilling, regardless of the conditions at the work site. It promotes the removal of cutting waste and collects all cutting waste without scattering it to the outside, allowing drilling work to be performed in a safe and clean condition! Our goal is to provide a construction method that can be carried out efficiently.

できる。Function: The construction method of the present invention is used when drilling holes in preparation for injecting adhesive into the required locations during repair work for lifting of the exterior or cracks on the walls of concrete buildings. Drill the drill so that it can come into contact with the position.
If you position the dust suction chamber of the dust collector and place the suction dust removal box against the wall, it will be connected to the suction pump in advance and activated, and the dust collector will be fixed to the wall with suction. Ru. Therefore, if you use a drill ftUIJ and apply it from the insertion hole of the dust collector to the drilling position on the wall surface and drill while supplying pressurized air, the inside of the crotch chamber is under negative pressure, so chips are sent to the cut product #'i. Together with the pressurized air, it passes from the dust suction chamber to the dust exhaust chamber, is quickly guided to the separator by four pipes, and is surrounded by a dust collector.
It is processed without leaking to the outside of the washer, which occurs in the S minute. When a hole is drilled to 4M i beyond the space created in the 9th part of the floating wall exterior, all the concrete chips that are cut into the space inside the wall are also suctioned away and spilled out to the outside. Drilling work can be performed cleanly without filling the voids. In particular, since dry processing can be performed without using any water during drilling, subsequent adhesive injection and other machining operations can be performed efficiently without limiting the conditions of the work site. When the suction power of the dust collector is reduced, the suction retention is released and the P
It can be simply removed from the wall and moved to the next working position.

A self-help pressurized injection type drug injector 01 (for example, the one disclosed in Tokusekki No. 61-4566 and Utility Application No. 60-27713) is inserted into the screw hole provided in advance. The syringe is fixedly attached by attaching the syringe to the syringe or by driving a metal anchor pin (not shown) into the syringe. C
After installing the syringe, put it away, unlock each drug syringe, and use the restoring force of the built-in TAS agent coil spring to move the piston f'PtIJ and press it into the cavity one by one. The adhesive is dispensed evenly around the location of each container. At this time, since the void in the six-drilled area for drug injection is cleaned of dust at the same time as drilling as described above, the adhesive quickly fills the void and can provide effective bond reinforcement. ■ Effects of the invention: If the construction method of the present invention is applied, the area around the drill that is being drilled will be surrounded by a dust collection tool with a simple structure that can be used to adsorb it to the wall surface using the dust suction power, and the drilling debris will be collected. All of these are collected in this dust collector, and during drilling, pressurized air is used to reduce drill cutting efficiency, and all dry processing allows drilling without contaminating the drilled area at all. No chips remain in the anchor holes or floating wall voids after drilling, and therefore the adhesive can be injected in a timely manner. Furthermore, as mentioned above, since drilling can be performed without using liquid, repairs can be made freely at any location in an existing building, and wall repair work can now be carried out economically and easily.
