[0002] The underwater concrete pouring construction of steel cofferdam bottom sealing needs to know the concrete pouring height at all times, and adjust the concrete pouring construction according to the pouring height. At present, the detection rope is commonly used to detect the concrete pouring height, which is detected by a special person every once in a while. The construction efficiency is low and difficult to do. Real-time monitoring of the process will bring difficulties to the construction of back cover concrete pouring

Embodiment Construction
[0018] Such as figure 1 As shown, it is a schematic diagram of the overall structure of a real-time monitoring device for underwater concrete pouring height according to the present invention. The device includes a lower floating ball 1, a scaled traction line 2 and an upper floating ball 3. between the densities, floating on the interface between the mud 5 and the concrete 4, the density of the upper buoy 3 is smaller than that of the air, floating in the air, and the two are connected by a drawn line 2 with scale.
[0019] As a technical optimization scheme of the present invention, the density of the lower floating ball 1 is controlled at 1.5 g / cm 3 ~1.7 g / cm 3 , with a diameter of φ200mm, using its density greater than mud 5 (about 1.1 g / cm 3 ) is less than concrete 4 (about 2.3 g / cm 3 ), the buoyancy and traction force received by the lower buoyant ball 1 is about its own gravity, so it floats on the interface between the mud 5 and the concrete 4 .

Abstract
The invention discloses a real-time underwater concrete spouting height monitoring device and a using method. The device comprises a lower floating ball, a pull wire with scales and an upper floatingball, wherein the density of the lower floating ball is between density of mud and density of concrete; the density of the upper floating ball is lower than that of air, the upper floating ball floatsin air, and the two floating balls are connected by the pull wire with scales. Since the density of the lower floating ball is between the density of mud and the density of concrete, the lower floating ball is always positioned in a suspended state in an underwater pouring process. Since the density of the upper floating ball is lower than the density of the air, the pull wire with scales is always positioned in a straight state, namely the upward floating distance of the lower floating ball along with concrete spouting is the same as an ascending distance of the upper floating ball, then theconcrete spouting height can be measured in real time by virtue of the pull wire with scales. According to the measuring device, the concrete spouting height during underwater concrete spouting construction can be monitored in real time, so that the concrete pouring construction is adjusted, the construction efficiency is greatly improved, and the construction quality is ensured.
Description
technical field [0001] The invention belongs to the technical field of underwater construction, and in particular relates to a real-time monitoring device for pouring height of underwater concrete and a use method thereof. Background technique [0002] The underwater concrete pouring construction of steel cofferdam bottom sealing needs to know the concrete pouring height at all times, and adjust the concrete pouring construction according to the pouring height. At present, the detection rope is commonly used to detect the concrete pouring height, which is detected by a special person every once in a while. The construction efficiency is low and difficult to do. Real-time monitoring of the process will bring difficulties to the concrete pouring construction of the back cover. Contents of the invention [0003] The object of the present invention is to provide a real-time monitoring device and method for underwater concrete pouring height in order to overcome the above-menti...
