Description

Cutting guide device for concrete with sludge removal function with sludge removal function

The present invention relates to a cutting guide device for concrete having a sludge removal function, and more particularly, by efficiently removing and discharging cutting sludge and dust derived from cutting a bridge pier or a building pillar made of concrete during the cutting operation and polluting it. It relates to a cutting guide device for concrete with a sludge removal function that can provide a working environment that minimizes

In general, as a work for dismantling concrete structures, a technology of cutting blocks (objects to be cut) such as concrete using a wire saw has been used for a long time.

After the wire saw is installed to wrap around the cutting object, the cutting object is cut while rotating the wire saw by driving the cutting equipment equipped with the wire saw.

According to the cutting of the wire saw as described above, a lot of dust is scattered and the cutting is made while the cutting material (concrete crushed material and rebar cutting sludge) is derived.

In order to prevent such dust and sludge contamination, the cutting position of the object on which the wire saw is disposed is cut by attaching separate covers to the cutting position, thereby obtaining an effect of preventing scattering of dust.

During continuous cutting of the wire saw, since a lot of heat is generated in the wire saw due to frictional contact with the cutting part of the object, the cutting is performed while spraying cooling water to the contact part through a high-pressure injector to cool it.

Due to the cooling water as described above, the sludge is rotated in a wet state and partially buried in the wire saw, and some of the sludge is accumulated on the inside of the cover provided on the outside of the cutting property, and the sludge gradually accumulates inside the cover. The cooling water supplied from the outside of the cover is partially discharged to the end of the cover or is discharged through a sludge outlet provided in the cover to prevent dispersion contamination of sludge and dust when cutting using a wire saw.

Looking at the source technology related to cutting and dust treatment of objects using the wire saw as described above, Republic of Korea Patent No. 10-2178300 (Name: Eco-friendly cutting system including sealed double pipe and sludge treatment device, Registration date: 11, 2020 Month 06, hereinafter referred to as 'Patent Document 1') and Registered Patent No. 10-1531173 (Name: Hybrid type concrete structure cutting and dismantling device using a diamond wire saw, registration date: June 18, 2015, hereinafter This is referred to as 'Patent Document 2') is disclosed.

The Patent Document 1 discloses a sealed double pipe in which the cutting wire can be mounted so that the cutting wire is mounted on the concrete structure to be cut and the installation is completed at the same time, and the cutting wire mounted in the sealed double pipe. The cooling water contained in the sludge generated during the structural cutting process used is separated and supplied to the sealed double pipe to be reused for the cooling treatment of the cutting wire.

The Patent Document 2 improves the cutting efficiency by mixing a small amount of water and high-pressure air when cutting a concrete structure to be dismantled using a diamond wire saw and spraying it on the cutting area in a mist spray method, It is designed to effectively prevent the scattering of residual dust.

That is, in the patent document, in cutting an object (concrete structure) using a wire saw, the sludge is treated, but the larger the cut cross-sectional area, the more the removal of the sludge generated during cutting is insufficient. This can solve the point of dust blowing in the mist spray method, but the method of spraying water (cooling water) with air inside the cover is adopted. A phenomenon of clogging the cover occurs, and such clogging by sludge ultimately adversely affects the cutting of the wire saw, and thus there is a problem that the cutting time is long due to inefficient cutting operation.
