Geological Instrument----JTG-1A Underwater Concrete Height Location Detector

Purpose:  

    By adopting the sensor structure that is suitable for running under water and the determination method that fixes the sensor under water, this instrument makes the constructor can control the concrete height location accurately when the pile is filling. It can decrease great waste for concrete source, reduce the difficulty for excavating, save cast for foundation engineering project constructing, and lessen circumstance pollution for burying redundant concrete block.

    The instrument is high automatization, high speed response, credible determination result and alarm on time, and it is the prior optional one for the company and research institute of working on high building, bridge, dock and harbor, oil extraction flat roof on the sea, nuclear power plant and other large foundation engineering projects.
