Concrete pool anti-cracking construction method
The invention belongs to the technical field of pool construction, and particularly relates to an anti-cracking construction method for a concrete pool, which comprises the following steps: reducing concrete by adopting low hydration heat, controlling the slump of the concrete, carrying out plate wall construction after a raft plate is stable, carrying out segmented pouring on the plate wall, reducing the temperature of concrete entering a mold and controlling the mold removal time of the plate wall. Compared with the prior art, the method has the advantages and positive effects that (1) after the raft plate is poured for seven days, raft plate concrete is contracted and basically stable, at the moment, the plate wall is poured, and large internal stress caused by simultaneous contraction of the plate wall and the raft plate after the plate wall is poured can be avoided; further, the board wall is poured in a segmented mode, the restraining force of the raft plate on the bottom of each segment of the board wall is small, and vertical cracks of the board wall are reduced; (2) the content of cement and water in the concrete is low, the hydration heat of the cement is reduced, the temperature rise of the concrete is small, and the risk of generating cracks is reduced; and (3) stones and sand with large particle sizes are selected to prepare concrete, so that the water consumption and the cement consumption are reduced, and the cement hydration heat is reduced.
本发明属于水池施工技术领域，具体涉及一种混凝土水池防裂施工方法，包括采用低水化热减缩混凝土、控制混凝土塌落度、在筏板稳定后再进行板墙施工、板墙分段浇筑、降低混凝土入模温度和控制板墙拆模时间；与现有技术相比，本发明优点和积极效果在于：(1)筏板浇筑七天之后，筏板混凝土已经完成收缩并基本稳定，此时再浇筑板墙，能够避免板墙浇筑后板墙和筏板同时收缩造成的大的内应力；进一步的，板墙分段浇筑，筏板对每段板墙的底部约束力小，减少板墙竖向裂纹；(2)混凝土中水泥和水的含量少，水泥水化热减少，混凝土温升小，产生裂纹的风险降低；(3)选用粒径较大的石子和砂子配制混凝土，减少用水量及水泥用量，使水泥水化热减少。
