Construction method and device for water cooling of gate pier large volume concrete of tide gate

Abstract

The invention discloses a construction method and device for water cooling of gate pier large volume concrete of a tide gate. The construction method for water cooling of the gate pier large volume concrete of the tide gate comprises the following steps that S1, a water cooling device is arranged; S2, steel bars are arranged; and S3, a tide gate is cast according to the principle that cooling water is introduced and then concrete is poured. In different time periods, the time interval of changing the direction of water introducing is different. The concrete temperature rise can be reduced during the casting and curing process of the gate pier, so that occurrence of cracks is avoided.

Description

technical field

[0001] The disclosure relates to the technical field of water conservancy engineering, in particular to a construction method and device for water-through-cooling construction of large-volume concrete pier of a tidal gate. Background technique

[0002] The pier of the tidal gate is a pier-type component used in the lock chamber to support the gate, separate the gate hole, and connect the two banks. The concrete of the pier is a kind of mass concrete. In actual engineering concrete pouring, temperature cracks often appear in gate piers. Cracks in the concrete of the gate pier not only destroy the integrity of the gate pier structure, but also affect the durability and safety of the building. Temperature cracks in sluice piers are very common, and the cracks pose a threat to the durability and safe operation of the sluice. During the pouring process, the cement releases a large amount of heat of hydration during the hardening of the concrete, and the internal...
