Foundation post-grouting method for final joint of immersed tube
The invention relates to an immersed tube final joint foundation post-grouting method, and belongs to the technical field of immersed tube butt joint, and the immersed tube final joint foundation post-grouting method comprises the following steps: grouting pipeline prefabrication, preparation work before grouting, grouting pipeline hoisting, grouting area plugging, grouting equipment connection and grouting. Wherein in the grouting pipeline prefabrication step, a first grouting pipe and a second grouting pipe are fixed in the same truss, and the first grouting pipe and the second grouting pipe are arranged in parallel; wherein the first grouting pipe is used for grouting in the area between the first end of the truss and the midpoint of the truss, and the second grouting pipe is used for grouting in the area between the midpoint of the truss and the second end of the truss. According to the method, the first grouting pipe and the second grouting pipe are fixed through the truss, and winding and knotting of grouting hoses used when the grouting pipes are connected with grouting equipment can be effectively avoided; by arranging the first grouting holes and the second grouting holes in a segmented mode, regional grouting is achieved, and it is guaranteed that grout is evenly distributed and fully solidified.
本发明涉及一种沉管最终接头基础后注浆方法，属于沉管对接技术领域，该沉管最终接头基础后注浆方法包括以下步骤：注浆管路预制、注浆前准备工作、注浆管路吊装、注浆区封堵、注浆设备连接、注浆；其中，注浆管路预制步骤中，将第一注浆管和第二注浆管分别固定于同一桁架内，第一注浆管和第二注浆管平行设置；其中，第一注浆管用于自桁架第一端至桁架中点之间区域的注浆，第二注浆管用于自桁架中点至桁架第二端之间区域的注浆。该方法通过桁架固定第一注浆管和第二注浆管，能够有效避免注浆管连接注浆设备时所用的注浆软管缠绕打结；通过分段设置第一注浆孔与第二注浆孔，实现分区域注浆，保证浆液的均匀分布和充分固化。
