Intelligent monitoring device and method for underwater concrete pouring elevation

Abstract

The invention discloses an intelligent monitoring device and method for underwater concrete pouring elevation. The intelligent monitoring device comprises a waterproof measuring probe 1, a cable 2 provided with scale marks as well as a portable intelligent monitoring terminal 3, wherein the measuring probe comprises a vibration signal generator 4, a vibration sensor 5 and a vibration conductive casing 6; and a concrete medium 9 has ingredients different from environmental media such as water, mud and the like and has different damping actions on a vibration signal, so that when the measuring probe is located in different media materials, the vibration signal amplitude values detected by the vibration sensor change, the intelligent monitoring terminal 3 is used for performing conversion treatment on the vibration signal, and automatic monitoring for the concrete pouring elevation is achieved. According to the intelligent monitoring device and method, different damping actions of different media on the vibration signal are used for monitoring the concrete pouring elevation, parameters are not needed to set, the measuring method is simple, the measuring accuracy is high, and the device has good portability.

Description

technical field [0001] The invention relates to an intelligent monitoring device and method for the concrete elevation in underwater concrete pouring construction, which is suitable for accurate monitoring of the underwater concrete pouring elevation under various complex conditions. technical background [0002] Underwater concrete pouring construction is very common in various infrastructure projects such as high-rise building foundations, underground engineering, ports, bridges, and wharves. The commonly used bored piles, because the pile top elevation is generally lower than the ground, and the pile is filled with water and mud, it is difficult to measure the concrete pouring elevation in time and accurately when pouring concrete, especially in order to prevent concrete pouring when pouring concrete in deep underwater pile holes. Insufficient pouring volume, to ensure construction quality, often requires pouring more concrete, which not only causes waste of concrete reso...

Problems solved by technology

The commonly used bored piles, because the pile top elevation is generally lower than the ground, and the pile is filled with water and mud, it is difficult to measure the concrete pouring elevation in time and accurately when pouring concrete, especially in order to prevent concrete pouring when pouring concrete in deep underwater pile holes. Insufficient pouring volume, to ensure the construction quality, more concrete is often poured, which not only causes waste of concrete resources, but also increases construction costs, and the over-poured concrete has to be cleaned up to bring environmental pollution problems and increase the construction volume

[0003] At present, some domestic measurement of underwater concrete pouring level adopts mechanical structure, which has a low degree of automation and poor accuracy; there are also automatic measuring instruments based on pressure sensors, which use the characteristics that the density of concrete materials is different from that of water and mud. The concrete level is measured through the pressure sensor. This method needs to set parameters according to different concrete design levels. The operation convenience is poor, and the sensor used for measurement is too heavy and large, which is inconvenient to use and carry, and the pressure sensor is easily affected by the concrete. Condensation affects the accuracy of measurement and is not easy to maintain; there are no such special monitoring instruments and equipment in foreign countries
