Problems solved by technology

[0002] The method of blasting and dumping silt dumping is widely used in coastal subgrade construction, land reclamation, port wharf and other projects. However, when blasting and silting operations are carried out in the coastal intertidal zone, the ebb and flow of tides have a greater impact on the construction effect of blasting and silting. When the tide is high, the blasting effect is better, but when the tide is low, especially when the silt surface is exposed to the water surface, the blasting effect is poor. In order to improve the blasting effect, blasting points are often arranged at low tide and blasting operations are carried out at high tide. The way of distributing explosives at low tide level and detonating at high tide level seriously reduces the construction efficiency and project quality of blasting and silting

Abstract

The invention discloses an intertidal zone blasting silt squeezing all-weather construction method. Two arc-shaped explosion lines are arranged and are detonated at the same time when tides rise, the height of a silt bag is pushed up to form a water storage depression, and after stone throwing and filling, single-line explosion lines are arranged; and when tides fall, the water level in a reservoir continues to be blasted, an underwater environment is provided, single-line explosion line blasting operation is implemented, and then stone throwing and filling are carried out. The cycle is repeated, and therefore all-weather underwater blasting is realized. According to the method, the rule of rising tides is utilized, the blasting construction efficiency is improved on the premise that the construction progress is not affected, and all-weather blasting silt squeezing construction is achieved.
