Comprehensive underwater vibration shock wave monitoring method

Abstract

The invention discloses a comprehensive underwater vibration shock wave monitoring method, which comprises the following specific steps of: a direction control adjusting rope is tied, a blasting vibration monitoring module and a ballast weight are vertically placed into water at a determined position, and a scale type pull rope is slowly lowered after the blasting vibration monitoring module and the ballast weight completely enter the water, so that the blasting vibration monitoring module is kept vertical; the blasting shock wave monitoring module is put into water, and a buoy is installed in time; when the stress on the scale type pull rope is suddenly reduced, the scale type pull rope is slowly tensioned and lifted upwards, so that the whole monitoring equipment has an adjusting capability, and the direction of the blasting vibration monitoring module is adjusted by utilizing the direction control adjusting rope, so that the blasting vibration monitoring module is horizontal; meanwhile, a scale type pull rope and a direction control adjusting rope are lowered, so that the bottom of the whole monitoring equipment is implanted; and the dip angle data is checked, if the dip angle meets the requirement, the scale type pull rope is properly and redundantly lowered, and normal monitoring operation can be carried out. According to the invention, the monitoring data quality is high, and the monitoring equipment is reasonable in structural design, high in practicability and high in stability.

Description

technical field [0001] The invention belongs to the technical field of underwater blasting monitoring, in particular to a comprehensive underwater vibration shock wave monitoring method. Background technique [0002] At present, underwater blasting operations have been widely used in many fields of the national economy, such as the construction of immersed tube tunnels, hydropower stations, port terminals, bridges and other structures, the dredging of ocean lakes, canals and bays, and the construction of dams, shipwrecks, etc. salvage and other fields. When our country vigorously utilizes underwater blasting to develop underwater resources, it encounters many problems, one of which is the shock wave and vibration hazards in blasting water. It mainly includes the impact on hydraulic structures in nearby waters, the impact on nearby surface ships, the impact on aquatic organisms in explosive waters, and the impact on workers in nearby waters. [0003] At present, the traditi...

Problems solved by technology

[0003] At present, the traditional monitoring of shock wave and vibration is carried out separately, and there are certain defects in the design of the monitoring device, and there are certain problems in the on-site monitoring, which leads to poor directivity of vibration measurement, and the shock wave monitoring is greatly disturbed by running water.
