Pouring and curing method for large-volume UHPC (Ultra High Performance Concrete)
The invention discloses a large-volume UHPC (Ultra High Performance Concrete) pouring maintenance method, which comprises the following steps that a plurality of circulating water pipes are manufactured, and a plurality of through holes are formed in the surfaces of the circulating water pipes; carrying out blocking treatment on the circulating water pipe so as to block a through hole in the circulating water pipe; pre-burying the circulating water pipes and connecting the circulating water pipes to form a circulating pipeline; uHPC is poured, and cooling water is injected into the circulating pipeline so as to cool the UHPC; after initial setting of the UHPC and before final setting of the UHPC, cooling water is stopped from being injected into the circulation pipeline, and blocking of the through holes in the circulation pipeline is relieved; cooling water is continuously injected into the circulating pipeline, and the UHPC is cooled and maintained; after maintenance is conducted for 14-21 days, moisture in the circulation pipeline is removed, and grouting materials are adopted for conducting grouting treatment on the circulation pipeline. The method has the advantages that the method is simple and convenient to operate; and cooling and maintenance of the large-volume UHPC are realized.
本发明公开了一种大体积UHPC的浇筑养护方法，所述养护方法包括以下步骤：制作若干循环水管，其中，在所述循环水管表面开设若干通孔；对所述循环水管进行封堵处理，以封堵所述循环水管上的通孔；预埋所述循环水管并将所述循环水管相连以形成循环管路；浇筑UHPC并往所述循环管路内注入冷却水以对所述UHPC进行降温；在所述UHPC初凝之后、终凝之前，停止往所述循环管路内注入冷却水，并解除对所述循环水管上的通孔的封堵；继续往所述循环管路内注入冷却水，对所述UHPC进行降温和养护；养护14‑21天后，除去所述循环管路内的水分，并采用灌浆料灌注处理所述循环管路。本发明的优点是：方法简单，操作方便；实现了对大体积UHPC的降温和养护。
