A method of using a static cracking agent for pile cutting in construction

Abstract

The invention discloses a soundless cracking agent for building pile chopping. A preparing method of the soundless cracking agent includes the steps of firstly burning limestone calcium carbonate different in size through a calcination furnace for 72 hours at the 2000 DEG C high temperature, taking out the burnt limestone calcium carbonate for cooling after 72-hour calcination, cracking the cooled limestone calcium carbonate through a cracking machine into 8 mm-12 mm particulate matter, and then packaging the particulate matter to form the long-strip soundless cracking agent which is 600 mm-800 mm in length and 60 mm-80 mm in width. According to the soundless cracking agent, required machines and required manual work are reduced, the construction site noise is greatly lowered, dust pollution is reduced, and the production force can be improved by about three times.

Description

technical field

[0001] The invention relates to the field of building construction, in particular to a static cracking agent used for cutting piles in buildings and a method for using the same. Background technique

[0002] Traditional pile cutting technology requires manual operation to break piles. Generally, a crusher, excavator and air compressor are used to break the bond between concrete and steel bars, and then break the concrete into small pieces before cleaning; This crushing process is very noisy, and the noise is very loud and the dust is very large, which is harmful to the health of pile chopping workers, and also pollutes the environment. It is also easy to cause a lot of concrete fragments, and it is very time-consuming.

[0003] During so many years of working in the construction industry, we have discovered that there are still many problems and inconveniences in the existing pile cutting technology, especially in the traditional processing process, it is nec...

[0015] A kind of static cracking agent used for cutting piles in construction. The preparation method of the static cracking agent is as follows: firstly, limestone calcium carbonate of different sizes is calcined through a calciner at a high temperature of 2000 degrees for 72 hours, and after calcination for 72 hours, it is taken out and cooled. After being crushed into granules with a size of 8-12mm by a crusher, the granules are packed to form a strip-shaped static cracking agent with a length of 600-800mm and a width of 60-80mm.

[0016] Such as figure 1 , figure 2 As shown, a method of using a static cracking agent for building cut piles, it first puts the polystyrene foam tube 1 on the steel bar 2 of the pile head, so that the steel bar 2 can be separated from the cement to prevent it from bonding, Then install strip static cracking agent 3 at the cutting place of the pile head, pour the cement concrete into the pile and bury the pile, and the strip static cracking age...
