[0002] With the continuous advancement of my country's urbanization process, the demand for infrastructure such as high-rise buildings, high-speed railways, highways, subways, docks, etc. is increasing. In the construction of these infrastructures, a considerable number of projects use pile foundations or pile support, and bored piles have become the most common pile-making technology in pile foundation or maintenance pile construction due to their advantages such as simple construction, high degree of mechanization, and little impact on the surrounding environment. However, the disadvantage is that bored piles are concealed projects, and their quality control is difficult, especially when pouring concrete underwater, it is necessary to accurately determine the height of the concrete pouring liquid level to ensure the quality of the concrete on the pile top.

[0003] In the prior art, for measuring the pouring of concrete on the pile top, a measuring hammer suspended from a measuring rope with a scale is usually placed in the pile hole for detection. However, since the measuring rope is easily deformed, the measurement is not accurate enough and errors are easily caused. Another method is to use a sampling bucket with a scale to scoop out slag and take samples to determine the concrete pouring position. However, this method is more complicated, and the pouring is still in progress when sampling and judging, and there is also a certain inaccuracy. In order to solve the problem, a liquid level monitoring device for underwater pouring of pile foundation concrete is proposed. Utility Model Content

[0009] A further improvement of the utility model is that the wedge-shaped insertion rod includes a slope plug fixed to its insertion end, and a pair of wedge-shaped locking blocks for clamping the slope plug are installed in the wedge-shaped slot in a relatively sliding manner in the horizontal direction. The wedge locking block includes a slope block and a pull rod connected to the slope block, and a pair of slide grooves for accommodating a pair of wedge locking blocks are provided on the opposite side walls of the wedge-shaped slot, and the slide groove includes a first accommodating space connected to the wedge slot and a second accommodating space connected to the first accommodating space and extending to the outside of the corresponding plug board, the slope block is connected to the first accommodating space by a connecting spring, and the pull rod passes through the connecting spring and extends out of the corresponding plug board after passing through the first accommodating space and the second accommodating space.
