Temperature Control and Crack Prevention Measures for Concrete Ship Locks Subjected to Prolonged Casting Interruptions

Table 2

Operating conditions for the computation.

Conditions	Placing temperature (°C)	Spacing of pipes	Water temperature (°C)	Silo surface insulation
Condition 1	25	1.0 m × 1.0 m	20	One-time placement
Condition 2	25	1.0 m × 1.0 m	20	Layered placement
Condition 3	25	1.0 m × 1.0 m	20	Placing by dividing the first layer of the concrete into two blocks
Condition 4	15	1.0 m × 1.0 m	15	Insulate the floor; equivalent heat release coefficient is 2.92 kJ/(m^2 h °C)
