Blasting method of drainage groove
The invention discloses a blasting method of a drainage groove. According to a blasting theory, after an explosive explodes at any point within a certain distance from the surface of a soil rock to the interior of the soil rock, the soil rock is crushed or thrown. The blasting performed by arranging an explosive cartridge on the surface of the soil rock is called surface contact blasting, and theblasting performed without covering the explosive cartridge is called exposed contact blasting. After the explosive cartridge after being subjected to exposed contact blasting is exploded, soil rock within a certain distance from the explosive cartridge can be crushed and a part of the soil rock is thrown away. The blasting performed by arranging the explosive cartridge in the soil rock is calledinternal blasting, a funnel pit is formed after the explosive cartridge is exploded, and the size of the funnel pit is related to the explosive load, the property and the structure of the soil rock. According to the blasting method of the drainage groove provided by the invention, a non-overflowing weir body and an overflowing weir body can be widened and deepened at the same time, the overflowingweir body is formed, the reinforcing effect of a reinforcing method is good in the season with much rainwater, and the safety guarantee of an overflowing channel is improved.
本发明公开了一种引流槽的爆破方法。本发明中，根据爆破理论，炸药在土岩表面至内部一定距离内任意一点爆炸后，都将使土岩被破碎或抛掷。将药包设置在土岩表面而进行的爆破称为表面接触爆破，对药包不加覆盖就称为裸露接触爆破。裸露接触爆破的药包爆炸后能将距药包一定距离内的土岩破碎并抛走一部分。将药包设置在土岩内部而进行的爆破称为内部爆破，药包爆炸后将形成一个漏斗坑，其大小与装药量多少和土岩性质、结构有关；本发明中，可以同时对未过流堰体和已过流堰体进行加宽加深，了过流的堰体，是的该加固方法在雨水较多的季节加固效果较好，提高了对过流渠的安全保障性。
