Research on Construction and Crack Prevention Technology of Large Volume Concrete Pouring in Construction Engineering
In response to the problem of long pouring time of large volume concrete,which leads to tem-perature change reaction and formation of concrete cracks,the topic of construction and crack prevention technology for large volume concrete pouring in construction engineering was studied.Binding the load-bear-ing steel bars of concrete structures in construction projects,using the form of steel bar binding to connect the steel bars,and arranging the position,spacing,and quantity of steel bars according to the requirements of the construction project to ensure the durability and safety of the concrete structure.In construction engineer-ing,the layered pouring of large volume concrete box beams ensures the quality of concrete pouring by diag-onally dividing the entire section of the box beam through continuous pouring.Maintain the large volume concrete pouring platform structure,use a wooden trowel to level the surface of the concrete,and use an iron trowel to compact and polish it to avoid rapid loss of moisture in the concrete and the occurrence of shrink-age cracks.By using case analysis,it was verified that the anti cracking effect of this technology is better and can be applied in practical life.
