[0004]
The object of the present invention is to provide a device and method for measuring seismic shear waves of dynamic ramming in order to solve the problem of the range of influence in the horizontal direction in the existing dynamic ramming construction process. When the rammer falls into the ramming pit, the process of measuring the shear wave in the horizontal direction generated by the rammer can be realized simply and efficiently to determine the horizontal influence range of the dynamic compaction construction

The invention provides a dynamic compaction earthquake shear wave measuring device and method. The measuring device comprises an engineering seismograph, a detection mechanism and a trigger mechanism. The wave detection mechanism comprises at least three 3-C wave detectors which are arranged at equal intervals and are sequentially connected through signal cables and are connected to the engineering seismograph; the trigger mechanism comprises a triangular steel plate suspended below a rammer and a steel anchor welded on the upper surface of the rammer, and the steel anchor and the triangular steel plate are respectively connected with a signal trigger interface of the engineering seismograph through cables. The rammer falls down from the ramming height, when the rammer makes contact with the triangular steel plate, the engineering seismograph receives signals, the detection mechanism starts to work, the actually-measured amplitudes of different distance measuring points are detected, a function formula of the actually-measured amplitudes and the distances is obtained, and then the dynamic compaction vibration influence energy levels at the different distances are sequentially calculated according to the formula. The device is simple in structure and convenient to use, and the influence range of dynamic compaction can be visually judged according to the magnitude of shear wave energy.
Description
technical field [0001] The invention relates to foundation engineering, foundation treatment construction methods and technical fields, in particular to a device and method for measuring dynamic tamping seismic shear waves. Background technique [0002] Dynamic compaction construction is mainly used to improve the bearing capacity of the foundation. It is mainly used in the construction industry and is widely used in construction projects and sea reclamation projects. Materials with better performance are strongly squeezed into the foundation to form a series of granular pier composite foundations in the foundation to improve the bearing capacity of the foundation and reduce settlement. During construction, a crawler crane with an automatic decoupling device is generally used to lift the rammer. [0003] During the construction process of dynamic ramming, when the heavy rammer falls freely and falls strongly after being decoupled, it will generate a strong impact force and ...
