Real-time monitoring system of condensing state of concrete and real-time monitoring method

Abstract

The invention relates to a real-time monitoring system and a real-time monitoring method of a condensing state of concrete and in particular relates to the real-time monitoring system used for determining the condensing time of the concrete according to change of a collected pressure value of a monitoring point location in a pouring process of the concrete. The real-time monitoring system comprises a monitor and a central processing unit connected with the monitor, wherein the monitor is arranged in a pouring template and connected with the central processing unit outside the pouring template by virtue of a signal transmission cable. By adopting the design of the monitor, the pressure value of the monitoring point location can be synchronously collected in real time. In addition, the monitor is small, exquisite and convenient and simple in setting and does not have effect on the structure of the concrete. By utilizing the real-time monitoring system, the measurement step is simplified, the construction process is accelerated, the construction cost is saved, and the work efficiency is improved.

Problems solved by technology

[0002] At present, in the concrete pouring construction of the subsea tunnel, in order to facilitate the vibration of the pouring formwork, there are full-length gaps with a width of 10.85m and 3.85m respectively on the upper part of the bottom plate located in the driving corridor and the middle pipe gallery. If the side wall of the pouring formwork If the concrete on the bottom and bottom slab has not reached the initial setting state and the side wall concrete is continuously poured, the bottom slab concrete will easily rise from the gap due to the pressure difference, which will seriously affect the construction accuracy; therefore, it is necessary to accurately determine the poured concrete during construction. Coagulation state

At present, the determination of the setting state of concrete is based on the determination of the setting time of concrete by the laboratory penetration resistance method, but because the construction environment is very complicated at the pouring construction site, this will cause the performance of fresh concrete to be different from that of the experiment. There are differences in the laboratory, the slump is lost, there are phenomena such as bleeding and segregation, and the on-site temperature conditions are changing, the coagulation time data obtained in the laboratory and the field are often quite different.
