Description

technical field

[0001] The invention relates to a large-volume concrete maintenance technology, and more particularly relates to an underground diaphragm wall condensation pipe device and a construction method. Background technique

[0002] In recent years, with the increase of deep foundation pit projects and the large-scale construction of urban subways and related municipal projects, large-scale underground diaphragm walls have been used more and more in China. However, during the hardening process of mass concrete, a large amount of heat of hydration will be released inside the concrete, resulting in large temperature changes. The resulting temperature stress and shrinkage stress will easily lead to cracks in the structure. Therefore, how to effectively control the heat of hydration inside the mass concrete and avoid the generation of temperature cracks has become the focus and difficulty of engineering construction. At present, the commonly used treatment measures in e...
