Environment protection explosion squeezing silting embanking method

Abstract

The invention discloses an environment protection explosion squeezing silting embanking method. Explosives inside each hole of explosive bags are divided into a plurality of evenly separated explosives in the order from top to bottom. An air cushion layer is fixedly arranged at the bottom of a section of explosives at the bottom layer, and the mode of blowing up the explosive bags sequentially in sections is adopted in a combination mode. The environment protection explosion squeezing embanking method has the advantages of being capable of buffering and wakening intense earthquake waves, high-pressure impact waves and high-decibel noises generated by the explosion in a short distances, being wider in application range, and capable of being used in areas with higher environment protection requirements like an cultivation area, an area near neighborhood and the like.

Description

technical field [0001] The invention relates to a method for building embankments by blasting and squeezing silt, in particular to an environment-friendly method for building embankments by squeezing silt by blasting. Background technique [0002] Most of the coastal areas in my country have relatively thick marine silt clay layers. During the foundation treatment, if conventional methods such as excavation are used to remove the silt, not only the cost is high, but also the technology is difficult. [0003] The technology of blasting and squeezing silt is one of the ten new technologies in the construction industry promoted by the Ministry of Construction. Blasting silting technology reduces the structural strength of the silt through the impact of the explosion, and at the same time uses the self-weight of the riprap body itself to make the riprap body in a balanced state before the explosion slide into the silt at the place where the strength is reduced, so as to achieve ...

AI Technical Summary

Problems solved by technology

However, on the one hand, the increase in the dose will cause strong vibration, high-pressure shock waves, and high-decibel noise during blasting, which will have a huge impact on the living environment of marine organisms, the lives of surrounding residents, and near-shore buildings. On the other hand, it is difficult to deal with the policy of blasting construction Large, it is easy to prolong the construction period

Therefore, the current method of conventional blasting to squeeze silt and embankment is not suitable for breeding areas, near residential areas and other areas with high environmental protection requirements.
