Experimental device for simulating 200-meter deep water blasting under moving water state

Abstract

The invention relates to an experimental device for simulating 200-meter deep water blasting under the moving water state. The technical scheme is that: the device is a hollow spherical tank (6); two observation windows (7) are symmetrically formed on the tank body of the hollow spherical tank (6) and are provided with organic glass; a working hole on the top of the hollow spherical tank (6) is provided with an installation cover (5) which is provided with three penetration holes (3) and a high pressure air pipe joint (2); the bottom of the hollow spherical tank (6) is provided with a water pipe joint (12); a lead (9) connected with explosive passes through one of the three penetration holes (3); a waterproof shielding cable connected with a pressure sensor (8) passes through another hole of the three penetration holes (3), and is connected with a data acquisition instrument (1); an electric stirrer (11) is arranged on the inner wall of the bottom of the hollow spherical tank (6); and a wire connected with the electric stirrer (11) passes through the third hole of the three penetration holes (3) and is externally connected with a power control device. The device has the characteristics of reasonable design, convenience of manufacture, and high similarity to actual environment.

Description

technical field [0001] The invention belongs to the technical field of blasting quasi-experimental devices. In particular, it relates to a 200-meter-level deep-water blasting experimental device under simulated dynamic water state. Background technique [0002] With the development of blasting technology, underwater engineering blasting is more and more widely used in blasting reefs, dredging channels, excavating foundation pits of hydraulic structures, excavating canals, underwater pipelines, underwater blasting and compacting, and deep-sea mining of petroleum engineering. Explosive demolition of post-waste, etc. [0003] Underwater engineering blasting refers to the process of extremely large energy conversion in a limited underwater volume in a very short time. Underwater blasting can be roughly divided into three stages: detonation of explosives, generation and propagation of shock waves, formation and pulsation of bubbles. The output energy of explosives in underwate...

AI Technical Summary

Problems solved by technology

Underwater blasting also includes many uncertain factors, such as the type of explosive in underwater blasting, the size of the charge, the distance from the explosive to the structure, the underwater environment, etc. All of the above characteristics make the research on underwater blasting quite complicated and difficult. difficulty

[0004] For this reason, the research on underwater engineering blasting technology has attracted the attention of relevant scientific and technological personnel. Although the simulated experimental device for underwater blasting has come out, the similarity with the actual environment is low, especially the deep water environment under dynamic water conditions. The experimental device has not been reported
