Layered staggered joint construction method for super-long and super-thick mass concrete
A layered staggered joint construction method for super-long and super-thick mass concrete comprises the following steps that firstly, layered staggered joint design is conducted, horizontal or vertical construction joints are formed in the mass concrete in the longitudinal direction and the transverse direction, and the mass concrete is divided into a plurality of pouring units; step 2, optimizing the mix proportion of the concrete, and reasonably selecting an additive; thirdly, the first pouring unit divided in the first step is constructed, and construction joint anti-leakage and anti-cracking measures are taken in the construction process; then concrete pouring and maintenance measures after pouring are carried out, and first-time concrete construction is completed; and step 4, sequentially carrying out construction, pouring and maintenance on other concrete pouring units according to a plan, and completing all concrete construction. According to the layering staggered joint construction method for the super-long and super-thick mass concrete, the problem that cracks are generated due to temperature stress in mass concrete construction can be solved.
一种超长超厚大体积混凝土分层错缝施工方法，包括如下步骤：步骤一、分层错缝设计，对大体积混凝土在纵向、横向设置水平或垂直施工缝，使大体积混凝土分为若干个浇筑单元；步骤二、优化混凝土配合比，合理选用外加剂；步骤三、进行步骤一中所划分出的第一个浇筑单元施工，在施工中做好施工缝防渗漏和防开裂措施；再进行混凝土浇筑以及浇筑后的养护措施，完成首次混凝土施工；步骤四、之后按设计划对其他混凝土浇筑单元依次进行施工、浇筑及养护，完成全部混凝土施工。本发明提供的一种超长超厚大体积混凝土分层错缝施工方法，可解决大体积和大体量的混凝土施工因温度应力产生的裂缝问题。
