The invention discloses a concrete formwork lateral pressure monitoring device and method. The device comprises a concrete formwork mechanism, a pressure measuring unit module, a pressure measuring module sealing mechanism, a pressure measuring module fixing mechanism and an optical signal processing unit, wherein the pressure measuring unit module comprises an elastic diaphragm stress base, a boss of the elastic diaphragm stress base is embedded into a through hole of the template, and a front end face of the boss and a front end face of the template are located on the same plane. The methodcomprises the following steps of calculating a lateral pressure value of concrete to a template through the change of the wavelength of reflected light after the grating of the pressure measuring unitmodule is stressed when the lateral pressure during concrete pouring is changed. The method is advantaged in that lateral pressure of concrete on the formwork can be accurately monitored in real time, whether the supporting state of the concrete formwork mechanism is safe or not, whether the concrete filling amount is uniform or not and whether concrete leaks or not are judged, and formwork collapse accidents are prevented. The device has advantages of high measurement precision, recycling, energy conservation and environmental protection.
Description
technical field [0001] The invention relates to the technical field of construction engineering, in particular to a device and method for monitoring the lateral pressure of a concrete formwork. Background technique [0002] In the technical field of construction engineering, cast-in-place concrete is a commonly used construction method in this field. The formwork is fixed in advance, and then the concrete slurry is injected. In many large-volume concrete pouring sites, the shapes of steel formwork are different, including vertical formwork, horizontal formwork and oblique formwork. The greater the depth, the greater the lateral pressure of the poured concrete on the formwork, especially for inclined formwork and transverse formwork, the greater the lateral pressure. In addition, in some harsh environments, there are more and more unmanned mechanized concrete pouring constructions. It is unknown whether there are hidden dangers such as leakage during concrete pouring, and wh...
