Hammer surface flying bullet accelerated supergravity dynamic compaction device and construction method
The invention discloses a hammer surface flying bomb accelerated supergravity dynamic compaction device and a construction method. The hammer surface flying bomb accelerated supergravity dynamic compaction device comprises a rammer, a plurality of explosive holes are formed in the rammer, flying bomb explosives are arranged in the explosive holes, each flying bomb explosive comprises an explosive shell, an initiating explosive bin is arranged in the explosive shell, a control module is arranged below the initiating explosive bin, and ignition powder is arranged at the top of the control module; a pipe plug is arranged at the top of the explosive shell, and a closed air chamber is formed between the pipe plug and the initiating explosive bin. Compared with a traditional dynamic compaction method utilizing gravitational potential energy, under the same falling distance and rammer, larger compaction energy can be provided, the compaction energy can be improved by 20%-50%, meanwhile, the falling distance height of the rammer can be reduced through the energy of explosives, and therefore the problem that the falling point is not accurate during falling is solved; through the closed air chamber, the rising and falling speed of explosion pressure can be reduced, the acting time can be prolonged, the utilization rate of explosion energy can be improved, and meanwhile due to the fact that the explosive bin and the explosive shell are made of light high-strength high-temperature-resistant alloy materials, explosion of the initiating explosive can be guaranteed.
本发明公开了一种锤面飞弹加速的超重力强夯装置及施工方法，包括夯锤，夯锤内部设有多个炸药孔，每个炸药孔内均设有飞弹炸药，飞弹炸药包括炸药外壳，炸药外壳内设有起爆药仓，起爆药仓下方设有控制模块，控制模块顶部设有点火药，炸药外壳顶部设有管塞，管塞与起爆药仓之间形成密闭气室。本发明较传统利用重力势能的强夯法，可以在相同的落距及夯锤下，提供更大的夯实能，夯实能越能提高20％‑50％，同时，可利用炸药的能量来减小夯锤落距高度，以此降低下落时落点不精确的问题；通过密闭气室可以减小爆炸压力上升和下降的速度，延长作用时间，提高爆炸能的利用率，同时由于采用由轻质高强的耐高温合金材料制成的药仓和炸药外壳，可以保证起爆药爆炸。
