5-59 how to detect the concrete structure of precast buildings?

Since its inauguration in November, the vocational skills training school for industrial workers of China Construction Third Engineering Bureau has officially opened and operated, and more than 20 trainees in the first phase have successfully completed the training.

In order to further improve the training strength and expand the business scope of the school, on December 18, Wuhan Zhonghe Engineering Technology Co., Ltd.

led and organized a number of testing institutions in the province to visit the school to carry out the evaluation of the testing and identification ability of precast integral concrete structures.

This structural inspection is mainly based on the 1:1 reduction of on-site construction nodes in the actual operation area of the school, from the roughness of the joint surface of concrete components, the plumpness of sleeve grouting, the plumpness of joint grouting, the length of reinforcement in the grouting sleeve / anchorage length of reinforcement, the defects of cast-in-situ joint surface, the solid strength of sleeve grouting material The precast concrete structure is tested by seven parameters such as the anchorage and pull-out force of embedded connectors.

Roughness detection of concrete component joint surface sleeve grouting plumpness detection of joint grouting plumpness detection of reinforcement length in grouting sleeve / reinforcement anchorage length detection of cast-in-situ joint surface defect detection at present, the detection of precast buildings has just started in China, and Hubei Province is also the first attempt.

The inspection is conducted in this school, which is not only a comprehensive evaluation of the inspection ability of the provincial inspection institutions for cast integral concrete structures, but also an approval of the school’s cast operation technology.

As the first pilot organization for testing precast buildings in the province, the vocational skills training school for industrial workers of China Construction Third Engineering Bureau will continue to improve the school’s practical environment for nondestructive testing of precast buildings according to the requirements of relevant specifications, and build the school into the first comprehensive training institution in Hubei Province with the ability of nondestructive testing of precast buildings and the qualification of training in key processes of precast buildings, Continue to provide NDT and post skilled talents for the cast construction industry, and contribute to the sustainable and stable development of the cast construction industry…
