Construction crack control method for super-long large-size concrete pool
The invention discloses a construction crack control method for a super-long large-size concrete pool. The method comprises the following steps that firstly, the generation reason of a crack of the concrete pool is analyzed, and then shrinkage cracks and the like in material requirements, the design of a raft foundation construction method in pouring and the design of a frame shear wall construction method are avoided, temperature cracks caused by temperature difference are avoided through temperature measurement point arrangement design and cooling method design of concrete temperature measurement, the situation that the cooling speed is not suitable to be too high is avoided through heat storage method curing of concrete curing, and cracks caused by temperature difference stress are prevented. Through the improvement of the method, cracks are less or even completely eradicated in the construction of the large-volume concrete pool, and the construction quality and work efficiency are guaranteed.
一种超长大体积混凝土水池施工裂缝控制方法，本方法首先分析混凝土水池裂缝产生原因，接着在材料要求、浇筑中的筏板基础施工方法的设计和框架剪力墙施工方法的设计避免了收缩裂缝等，混凝土测温的测温点布置设计以及降温方法设计避免了温差产生温度裂缝，混凝土养护的蓄热法养护，避免了降温速度不宜过快，以防温差应力产生裂缝。通过本方法的完善，使大体积混凝土水池施工中裂缝产生较少甚至杜绝，保证了施工质量工效。
