Rock wall crane beam concrete temperature control method, device and system
The invention discloses a rock wall crane beam concrete temperature control method, device and system. External water is injected into a heating water tank through a make-up water pipe, is heated to be injected into a constant temperature water tank, flows into the end of rock wall crane beam concrete through a pipeline pump and a water inlet pipe, and is connected with a water spraying pipe to bepaved to the concrete surface; cofferdams are built on a rock wall crane beam; a drain hole is reserved in the other end of water inlet pipe to be connected with a water return pipe; water returns into the heating water tank to form a temperature control maintaining water circulating system; and a layer of plastic film and a quilt cover the upper part of a concrete cabin surface to form a thermalinsulating layer. The concrete surface temperature is adjusted through adjusting the water temperature to enable the internal and external temperature difference of concrete to be less than 20 DEG C,so that the internal and external temperature difference of concrete carries out thermal insulation and heat storage on the external part of concrete and sealing on an organic thermal transmission medium to ensure constant and uniform radiation of hydration heat so as to reduce cracks in concrete caused by excessively large temperature difference; and generation of surface desiccation cracks is reduced through isolation moisture retention and water curing duration prolonging at the external part.
本申请公开一种岩壁吊车梁混凝土温控方法、装置及系统。外部供水通过补给水管注入到加热水箱内，加热后注入恒温水箱内，通过管道泵、进水管至岩壁吊车梁混凝土的端头，连接洒水花管铺设至混凝土表面，在岩壁吊车梁修筑围堰，在进水管的另一端预留排水孔连接回水管，水回流至加热水箱内，形成温控养护水的循环系统，混凝土仓面的上部覆盖一层塑料膜和棉被形成保温隔热层。通过调整水温来调整混凝土表面温度，使混凝土的内外温度差小于20℃，这样混凝土内外温差通过对混凝土外部进行保温蓄热、有机热传递介质封闭来保证水化热持续均匀散发，以减少因温差过大导致混凝土内部出现裂缝；外部通过隔离保湿、延长水养时长减少表面干缩裂缝的产生。
