Abstract

The invention discloses an anti-seam temperature control pouring method and structure for foundation mat mass concrete. The method is characterized by comprising the following steps that a water through cooling device is arranged in a space to be poured of mat concrete, and cooling water is used for water through cooling; concrete is poured into the space to be poured; a heat-storage humidity-preservation heat-preservation measure is adopted for the surface of the mat concrete finishing pouring; and die removal is carried out on the mat concrete.

Description

technical field [0001] The present disclosure generally relates to the technical field of civil engineering, and in particular to a joint-proof and temperature-controlled pouring method and structure of large-volume concrete on a foundation floor. Background technique [0002] With the in-depth development of my country's infrastructure construction, a large number of large-volume concrete projects have been built, such as dams, hydropower stations, water diversion and drainage structures, etc. During the construction of mass concrete projects, a series of quality problems appeared. Among them, concrete temperature crack is a quality control point in mass concrete construction. In mass concrete, temperature stress and temperature control are of great significance. During construction, due to a series of problems such as construction reasons, large temperature differences, and concrete deformation and constraints, concrete often has temperature cracks, including some fine cr...
