The method of pouring underwater concrete by a conduit is one of important procedures. The pipe interface adopts screw thread or flange connection, and the hole depth and the total length of the pipe should be calculated before the pipe is placed. Proper amount of retarder should be added into the concrete, so that the initial setting time of the concrete is longer than the pouring time of the whole pile. When the concrete is poured, the water sealing plug under the funnel can adopt a precast concrete plug, a wood plug or an inflatable bladder. After the first batch of concrete is poured, the concrete should be continuously poured, and stopping in the midway is forbidden. In the process of pouring, the real-time monitoring of the concrete liquid level is very important, the position of the concrete liquid level in a well hole is frequently detected, the buried depth of a guide pipe is timely adjusted, the buried depth of the guide pipe is controlled to be 2-6 m, and the guide pipe is strictly forbidden to lift the concrete surface so as to avoid pile breakage of a concrete structure. The effective monitoring of the concrete liquid level is the key to ensure the construction quality of underwater concrete. The rope measurement method is more direct effective to the little concrete liquid level height monitoring of degree of depth, but the rope measurement often can receive steel reinforcement cage's interference and can't effective accurate measurement when the degree of depth is great.
