Combined with the case of Liaocheng People s Hospital Building Project, this paper emphasized on winter seamless construction technique of mass and over-length con.

Practice of the jointless construction technology of the super-long concrete structure;

On the setting of the expansion-reinforcing band in the over-long concrete structure jointless construction

From three aspects: design mechanism,shrinkage-compensating concrete and mix proportion design jointless construction plan of concrete is introduced.

The application of concrete seamless construction technology;

The technology application of underground steel concrete seamless construction in winter;

The constructing methods of expanding concrete and strengthening belt in UEA seamless construction are elaborated in detail,so as to reduce the constructing period and project cost.

This paper analyzes existing developing condition of concrete structure design,introduces after-pouring joint construction and non-joint construction method,compares their characteristics,summarizes their advantages and disadvantages,and points out that people should take reasonable choice according to concrete engineering condition to ensure construction quality.
