Construction process for pouring underwater concrete
The invention discloses a construction process for pouring underwater concrete, which belongs to the technical field of pile foundations, and comprises the following steps: step 1, pouring the underwater concrete by adopting a vertical lifting guide pipe method, before a guide pipe is used, carrying out a lengthening airtight test, manufacturing a guide pipe support frame by using profile steel, supporting the support frame on a drilling platform for supporting and suspending the guide pipe, 2, underwater concrete construction is conducted, concrete mixing is conducted in a unified mode through a mixing station, and concrete is transported through a tank car and poured in cooperation with a guide pipe. According to the construction technology for pouring the underwater concrete, guide pipe concrete pouring can be completed underwater, a poured pile foundation has good structural strength, foaming control is good, the integrity of the pile foundation is high, and the problems that underwater impurities and gravels affect the pouring process and the quality of the pile foundation is reduced to the maximum extent are solved; and the quality problem caused by guide pipe mounting and dismounting is avoided.
本发明公开了一种灌注水下混凝土的施工工艺，属于桩基技术领域，包括以下步骤：步骤一、采用直升导管法进行水下混凝土的灌注，导管使用前，进行接长密闭试验，导管支撑架用型钢制作，支撑架支垫在钻孔平台上，用于支撑悬吊导管，步骤二、水下混凝土施工由拌和站统一进行混凝土拌制，混凝土采用罐车运输并配合导管灌注。该灌注水下混凝土的施工工艺，可以在水下完成导管混凝土浇筑，浇筑的桩基具备良好的结构强度，起泡控制较好，桩基完整性较高，避免了水下杂质和碎石，影响到浇筑过程，最大程度降低桩基的质量问题，避免采用导管安装和拆卸导致的质量问题。
