Diamond wire saw cutting reinforced concrete structure

Generally, the construction workers of underground deep foundation pit all know that there is a kind of reinforced concrete waist beam and support in the supporting structure of foundation pit, which takes time and effort to demolish, but the diamond wire saw cutting demolition greatly improves the construction efficiency and reduces the cost. Let's see the demolition method below. 

Firstly, according to the hoisting capacity of the hoisting machinery outside the pit, the size of the reinforced concrete structure blocks is determined, and the lines are divided into blocks. 

Drilling holes from top to bottom with water drills on each piece are hoisting holes and rope saw holes. 

Then, two main bars are chiseled at the corner of the upper surface of the reinforced concrete support to ensure that the cut blocks do not fall off. 

The diamond wire saw is perforated and installed, and the power supply is started to cut. Generally, it can cut a square metre section in an hour. The efficiency is still very high. Finally, the structure blocks under the cutting are lifted.
