Super high-rise building foundation raft construction method
The invention provides a super high-rise building foundation raft construction method. The super high-rise building foundation raft construction method comprises the steps that a foundation pit is excavated and supported, then a main chute and an auxiliary chute are arranged, the main chute communicates with the center of the foundation pit, the auxiliary chute is arranged in the foundation pit, then a formwork is erected, a temperature control system is preset in the foundation pit, and the temperature control system comprises a temperature monitoring device, water circulation and a plurality of temperature adjusting units. The water circulation supplies water to the temperature adjusting units, cooling water input into the temperature adjusting units through the water circulation is adjustable in a single point mode, then concrete is poured into the center of the foundation pit from the main chute, the concrete is annularly diffused to the periphery and poured in a layered mode, a formwork hanging area is poured through an automobile pump, film covering is conducted after initial setting, finally, a water retaining device is arranged on the periphery of the foundation pit, and water is injected into the water retaining device. And storing water and maintaining. The water circulation determines whether to input the cooling water to each temperature adjusting unit or not according to the internal temperature condition, the cooling water input at each point is independently controllable, temperature difference can be better reduced, temperature stress can be better controlled, finally water storage maintenance is carried out, and therefore generation of harmful cracks is reduced.
本发明提供了一种超高层建筑基础筏板施工方法，先开挖基坑并支护，其次设置主溜槽和辅溜槽，主溜槽与基坑中心连通，辅溜槽设置于基坑内，接着支模，然后在基坑内预设控温系统，控温系统包括温度监测装置、水循环和若干调温单元，水循环向各调温单元供水，水循环输入各调温单元的冷却水单点可调，再自主溜槽向基坑中心浇筑混凝土，混凝土向周缘环形扩散，分层浇筑，吊模区域通过汽车泵浇筑，待初凝后覆膜，最后在基坑周缘设置挡水装置，向挡水装置内注水，蓄水养护。水循环根据内部温度情况决定是否向各调温单元输入冷却水，各点冷却水接入单独可控，更利于缩小温差，能更好的控制温度应力，最后进行蓄水养护，从而减少有害裂缝的产生。
