Deep excavation cutting and controlled blasting excavation construction method thereof
The invention provides a deep excavation cutting and a controlled blasting excavation construction method thereof. A blasting excavation system is composed of four parts which are an extraction type drainage device, a rapid blast hole feeding and blocking device, a flying stone covering protection system and a ballasting double-row protection system. Collected water in a blast hole is pumped out through the extraction type drainage device, emulsion explosives are added through the rapid blast hole feeding and blocking device, and yellow mud is filled for blocking, the flying stone covering protection system covers the portion above the blast hole, the ballasting double-row protection system is arranged between a housing building house needing to be protected and a blasting area, and therefore existing buildings are prevented from being damaged by flying stones in the blasting process; and according to the deep excavation cutting and the controlled blasting excavation construction method thereof, the blast hole is high in drainage efficiency, charging and blocking are easy to operate, large-scale flying stones cannot be generated, the influence of blasting on the surroundings is small, the safety coefficient is high, and good economic and technical benefits are achieved.
本发明提供一种深挖路堑及其控制性爆破开挖施工方法，所述爆破开挖体系由抽提式排水装置、炮孔快速加料及堵塞装置、飞石覆盖防护体系、压重双排防护体系四部分组成，炮孔内集水通过抽提式排水装置进行抽出，通过炮孔快速加料及堵塞装置进行添加乳化炸药，并填充黄泥进行堵塞；飞石覆盖防护体系覆盖于炮孔上方，压重双排防护体系设置于需要保护的住房建筑屋与爆破区域之间，防止起爆过程中，飞石对既有建筑物的损坏，本发明炮孔排水效率高，装药及堵塞简单操作，不会产生大规模的飞石，爆破对周边的影响少，安全系数高，具有较好的经济技术效益。
