A large shell blasting destruction protection device for a beach sludge environment

By using sheet piles to enclose the disposal pit in the tidal flat silt environment and filling it with water to cover it with a splash guard, the problem of collapse and shrapnel scattering caused by traditional blasting methods in the tidal flat silt environment was solved, achieving a safe and efficient shell disposal effect.

AI Technical Summary

Technical Problem

In tidal flats and silt environments, traditional blasting methods are prone to causing collapses, and the vibrations and shrapnel from the explosion of large shells endanger surrounding buildings and nearby aquaculture, affecting the effectiveness of the destruction and operational safety.

Method used

The disposal pit is formed by a ring structure of multiple steel sheet piles. The bottom of the pit is lined with wooden planks, and shells are placed inside, along with emulsion explosive packs. The pit is detonated using industrial electronic detonators. Water is poured into the pit and it is covered with a splash guard. A protective dam is set up around the pit to absorb the shock wave and prevent shrapnel from scattering.

Benefits of technology

It effectively prevents the collapse and shrapnel scattering during shell explosions, reduces the propagation of blast shock waves and noise, protects the surrounding environment, and uses readily available and inexpensive materials, reducing construction difficulty and improving economic efficiency.

Abstract

This utility model belongs to the field of engineering blasting technology. It provides a protective device for the blasting and disposal of large artillery shells in tidal flat silt environments. The device includes multiple steel sheet piles driven into a silt foundation to form a ring structure. A disposal pit is created on the surface of the silt foundation, inside the ring structure. The pit walls are made of steel sheet piles, and a wooden board pad is laid at the bottom. This utility model uses tensile steel sheet piles to form a cofferdam, followed by mechanical excavation to quickly create the disposal pit. The steel sheet piles reinforce the perimeter of the disposal pit, preventing collapse, absorbing shock waves, and preventing shrapnel scattering. After the shells are blasted and disposed of, the tensile steel sheet piles can be recycled. The materials used in this utility model are inexpensive and readily available, effectively reducing construction difficulty and increasing economic benefits.
