Embodiment 1

[0042] Embodiment 1: If the project is constructed in a shallow sea area, when the area affected by the blasting vibration is within the scope of the low tide mud bag, the combination of differential blasting and dew beach blasting is used for construction; the construction layout is as follows figure 1 , figure 2 , image 3 .

[0043] 1. Determination of explosive filling parameters. According to the geological exploration report, geotechnical calculation principles and design height of the embankment, the height of the dike body is determined after theoretical analysis and calculation. Under the premise that the embankment crest is not super high after water explosion, the height of the embankment should be as high as possible to achieve the effect of silting to the greatest extent; then, according to the calculated height value of the embankment and the designed section of the embankment, the width of the embankment is calculated. The volume of filling in the widened pa...

Embodiment 2

[0073] Example 2: The seawater in the explosive filling construction area of ​​the project is relatively deep, or the project advances to the deep sea with the construction. When the low tide level, the area affected by the blasting vibration is within the seawater range, and the combination of differential blasting and air bubble curtain is used for construction; the construction layout is as follows Figure 4 , Figure 5 , Figure 6 .

[0074] 1. Determination of explosive filling parameters. According to the geological exploration report, geotechnical calculation principles and design height of the embankment, the height of the dike body is determined after theoretical analysis and calculation. Under the premise that the embankment crest is not super high after water explosion, the height of the embankment should be as high as possible to achieve the effect of silting to the greatest extent; then, according to the calculated height value of the embankment and the designed ...

Abstract

The invention relates to an environment-friendly blasting compaction method for treating a soft foundation, which is characterized in that: the environment-friendly blasting compaction method for constructing a dike starts with blasting shock wave energy and a transmission medium, reduces the blasting shock wave energy, changes the blasting influence transfer pathway and blocks the transmission medium of the shock wave; microsecond blasting is preferred; a construction method of combining the microsecond blasting with an exposed beach blasting is utilized when the blasting vibration influence area is in the range of low-tide dike head silt packets; and a construction method of combining the microsecond blasting with an air bubble curtain is utilized when the blasting vibration influence area is in the range of seawater in the lowest tide. The environment-friendly blasting compaction method for treating the soft foundation has the good effects of reducing the energy generated by the blasting compaction, blocking the transfer pathway of the blasting shock wave, reducing the powerful shock wave, the intense vibration and the noise generated by the blasting to the minimum and realizing blasting compaction environmental-friendliness construction.

Description

technical field [0001] The invention relates to an environmental protection technology for blasting and silting and soft foundation treatment, which is suitable for blasting and silting and soft foundation treatment construction in breeding areas, near residents, and other areas with high environmental protection requirements. Background technique [0002] Blasting and silting technology is one of the ten new technologies in the construction industry promoted by the Ministry of Construction. There are often thick marine silt muddy clay layers in coastal areas of my country. If the foundation treatment uses silt removal, it is not only expensive but also technically difficult; The explosive silting method 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 to make the riprap body in a balanced state before the explosion slide into the silt at the place where the strength is redu...
