Problems solved by technology

The main disadvantages of this technical method are: underwater drilling requires a lot of construction equipment and manpower, after the hole is formed, it often needs to be protected, the charge is difficult, and the construction process is complicated
The main disadvantages of this technical method are: the construction process of underwater drilling is complicated, and the drilling through the casing is prone to blockage, resulting in the inability to complete the charge.
The main disadvantage of this invention is that the plastic explosive in the annular groove needs to be detonated to explode when the instrument is released, and the instrument will be damaged if a little careless operation is made.

Abstract

The invention discloses underwater blasting explosive bin installation equipment and an installation and blasting method in the technical field of water conservancy projects. The equipment consists of two parts, namely a thruster and an explosive bin, wherein the thruster comprises an excitation motor, a global position system (GPS) position indicator, a displacement sensor, a lifting electromagnet and a shell; and the explosive bin comprises explosive, a detonation body, an armature and an explosive bin shell. Operation of combining and separating the thruster and / from the explosive bin is implemented according to the electromagnetic technical principle. The explosive bin can invade a soil body under the actions of excitation force and gravity of the motor of the thruster, after the explosive bin reaches the preset burial depth, the thruster is separated from the explosive bin, and the explosive bin is installed and the thruster is recovered. Therefore, by the underwater blasting explosive bin installation equipment, a construction process of underwater drilling and explosive charging can be eliminated, the working efficiency is improved, the technology is implemented easily, the thruster can be recovered to be repeatedly used, and the construction cost is low.

Description

technical field [0001] The invention relates to an underwater blasting technology in the field of water conservancy engineering, in particular to an installation equipment and an installation blasting method for an underwater blasting magazine with dynamic burial. Background technique [0002] Underwater blasting technology has experienced more than 20 years of development and is widely used in different industries such as water conservancy, military affairs, and water transportation. For example, in projects such as channel dredging, underwater excavation, and silting embankment, underwater soft foundations are treated by blasting. Compared with conventional construction techniques, it does not require large-scale construction equipment and complicated construction techniques, and has the advantages of manpower saving. , less investment, short construction period and other advantages, more and more attracted the attention of the engineering community.
