Building grouting plumpness detection device and detection method

Abstract

The invention discloses a building grouting plumpness detection device which comprises a signal transmitting module, a signal receiving module and a data processor. The signal transmitting module comprises a USB (universal serial bus) data interface, an electric quantity display module, an adjustment switch, an encoding signal storage module, a power module, an excitation signal transmitting switch, a signal amplifying module, an encoding signal input interface, a super-magnetic vibration module and a convertible transmitting module. The building grouting plumpness detection device has the advantages that an adjustable excitation signal forming technique method is combined with an adjacent frequency difference analyzing method, the device is simple to operate and high in sensitivity, discrimination precision is improved, and on-line real-time detection of large concrete structures can be performed.

Description

technical field [0001] The invention relates to a building construction auxiliary device and a construction method, more specifically, to a building grouting plumpness detection device and a detection method. Background technique [0002] At present, a large number of prestressed concrete bridges dominate the bridge construction in our country, and are widely used in important bridge construction projects including cross-sea bridges. For prestressed concrete bridges, the corrosion of prestressed tendons caused by insufficient grouting in the tunnel is a very important aspect to reduce the effective prestress. Full grouting of prestressed tunnels to ensure that prestressed tendons avoid premature corrosion has always been the focus and difficulty of construction control. However, there is still a lack of systematic, rapid and effective methods and technologies for detecting and evaluating the density of grouting in the tunnel that affects the durability of the structure. ...

Problems solved by technology

Although this method can intuitively see the degree of compactness, it causes damage to the wall and poses an indelible hidden danger to the weakening of the building structure. The damaged wall needs to be repaired again later, and the process is cumbersome and complicated. At the same time, there are limitations to simply observing with the naked eye, because if it is quantitative, the naked eye cannot be specifically determined and measured
