The post-installed anchor method is a technique used in the construction of new concrete structures, as well as in renovation and seismic reinforcement work, and for the installation of various equipment. It involves drilling into already hardened concrete and fixing anchors within those holes. There are many types of post-installed anchors, which can be broadly classified into metal anchors and adhesive anchors. Common metal anchors expand by driving or tightening the inserted anchor portion in the drilled hole, creating a wedged state to achieve holding power, and are used for relatively light installations. Additionally, there are various types of adhesive anchors, with capsule-type anchors being commonly used due to their ease of quality control. Capsule-type anchors consist of a capsule that contains the main resin, curing agent, and aggregate separated within a glass tube. This capsule is inserted into a drilled and cleaned hole, and by applying rotational impact to the anchor with a hammer drill while stirring the capsule, the resin is chemically cured, allowing the anchor to bond with the base material, making it suitable for applications where strength is required.

Core drilling work involves rotating a core bit embedded with diamond abrasives at high speed, utilizing the cutting power of diamonds to drill through various materials such as reinforced concrete. Water or other fluids are supplied to the cutting edge during the drilling process to remove cutting dust and cool the bit, resulting in a method that produces little to no dust, vibration, or noise. The machine is anchored to provide reaction force, allowing it to be compact and lightweight, making it suitable for work in narrow spaces, achieving high-precision drilling with a wide range of drill diameters from φ28 to 600, accommodating various applications.

Wall saw construction involves fixing a guide rail along the cutting surface of the material, attaching a diamond blade embedded with diamond abrasives to the spindle of a lightweight special drive unit on that rail, and moving it along the rail while rotating it at high speed and injecting cooling water to perform the cutting. Because it moves along the rail for cutting, it allows for precise and safe construction, resulting in a very clean cut surface. Similar to wire saws, it is a low-noise, vibration-free method that produces minimal dust.

Wire saw construction involves wrapping a diamond wire saw, which consists of diamond beads with diamond abrasives embedded in the wire and arranged at regular intervals, around the object to be cut. The ends are connected in a loop, and the cutting direction is adjusted using guide pulleys. The wire saw is driven to rotate at high speed while applying a constant tension, allowing for cutting. The wire saw is highly flexible, not constrained by the shape of the object being cut, and enables easy cutting of large cross-sections by adjusting the length of the wire saw. This method is low-noise, vibration-free, and uses cooling water for cutting, resulting in minimal dust generation.
