Seamless construction process for super-large-area concrete ground
The embodiment of the invention discloses a seamless construction technology for an ultra-large-area concrete ground, and belongs to the technical field of concrete construction technologies, cement, sand, stones, a concrete admixture and fly ash are included, no expansion joint or post-cast strip is reserved in seamless construction of the concrete ground, concrete is poured in a whole structure plane in a comprehensive layered mode, and the concrete is poured in a layered mode. And it is guaranteed that when the second layer is poured back after the first layer is poured, concrete poured on the first layer is not initially set, the operation is conducted layer by layer till pouring is finished, construction is conducted along the short edge and along the long edge, the construction is divided into two sections when necessary, the operation is conducted from the middle to the two ends or from the two ends to the middle at the same time, and the pouring thickness is not larger than 50 cm. The problem that due to the fact that the concrete is large in contractility, poor in ultimate tensile capacity and uneven in pouring face, the concrete is prone to cracking after being poured is solved. The method has the advantages that the concrete construction process is more rigorous and scientific, the problems of cracks and ground collapse are prevented, and meanwhile, the method is more environment-friendly.
本发明实施例公开了一种超大面积混凝土地面无缝施工工艺，属于混凝土施工工艺技术领域，包括水泥、沙、石子、混凝土外加剂、粉煤灰，在混凝土地面无缝施工中不留设伸缩缝和后浇带，在整个结构平面内全面分层浇筑混凝土，并保证第一层浇筑完后回来浇筑第二层时，第一层浇筑的混凝土还未初凝，如此逐层进行，直至浇筑结束，施工时沿短边开始，沿长边进行，必要时也要分两段，从中间向两端或两端向中间同时进行，浇筑厚度不超过50CM。解决了由于混凝土收缩性大和极限抗拉能力差以及浇筑面不平整而导致的混凝土浇筑后易形成开裂问题。具有对混凝土的施工工艺更加严谨，科学，防止产生裂缝以及地面塌陷的问题，同时，更加环保的优点。
