Maintenance device for mass concrete wall crack control

A curing device for mass concrete wall crack control comprises a water storage unit, a water inlet pipe, at least one cooling unit and a recovery pipe, wherein the two ends of the recovery pipe are connected with the cooling unit and the water storage unit respectively. By arranging the water storage unit, the water inlet pipe, the cooling unit and the recovery pipe, on the basis of achieving the purpose of cooling the interior of the concrete, the temperature rising water flowing through the interior of the concrete is further recovered and effectively cooled, the water temperature in the water storage unit is prevented from rising, and the service life of the concrete is prolonged. The technical problem that the cooling effect becomes poor gradually is solved. 一种大体积混凝土墙体裂缝控制的养护装置，包括储水单元、入水管、至少一个冷却单元、以及两端分别与冷却单元和所述储水单元连接的回收管。本实用新型通过设置储水单元、入水管、冷却单元、回收管的方式，在达到对混凝土内部进行降温冷却的基础目的上，进一步对流经混凝土内部的升温水进行回收并有效降温，避免了储水单元内部水温升高，解决了降温效果逐渐变差的技术问题。
