Positioning pouring device for underwater concrete

Technical Field

The application relates to the field of underwater concrete construction, in particular to a positioning pouring device for underwater concrete.

Background

The concrete cast-in-place pile foundation has become one of the most common foundation types in buildings at home and abroad due to the advantages of high bearing capacity, good stability, small settlement, small influence by the construction water level or the position water level and the like.

The bored pile is used as a concealed project, the quality control difficulty is high, particularly when concrete is poured underwater, the concrete is always positioned under slurry in a hole, and workers are difficult to judge the poured height of the concrete, so that the problems of insufficient pouring height or overhigh pouring height are easily caused, when the poured height of the concrete is insufficient, a pile head needs to be poured again, and the construction cost is high; when the concrete pouring height is too high, pile heads need to be chiseled off, so that concrete waste is caused, and the workload of construction personnel is increased.

In order to grasp the pouring height of concrete in time, a measuring hammer is usually tied on a measuring rope with length scale marks and is put into a hole, and a constructor judges the pouring depth of the concrete according to the downward feeling of the measuring rope.

With respect to the related art among the above, the inventors consider that the following drawbacks exist: the control of the concrete pouring depth is controlled by a measuring hammer method by means of feeling of constructors, and is generally influenced by various factors such as construction experience, on-site concrete quality, measuring hammer weight and the like, so that the condition that the exact height of concrete is not easy to judge is caused.
