Ultradeep impervious wall grooving method
The invention discloses an ultradeep impervious wall grooving method. The ultradeep impervious wall grooving method includes the steps that a groove hole is formed with a composite blasting method asfor the situation that an impervious wall needs to be embedded into riverbed high steep slope bed rock, wherein a first drilling machine is used for drilling a riverbed steep slope, so that a drill hole penetrating through a covering layer into a bed rock steep slope bevel is formed; a first blasting device is arranged below the drill hole and positioned on the steep slope bevel, and the first blasting device is used for blasting the steep slope bevel into a flat bevel; a second drilling tool is used for continuing to drill the bed rock below the flat bevel to form a blasting hole, and a second blasting device arranged in the blasting hole is used for blasting the bed rock below the flat bevel; and a third drilling machine is used for continuing to break and drill the blasted bed rock until an end hole is formed. According to the method, the ultradeep impervious wall can be grooved under the condition that construction conditions are harsh, the impervious wall is embedded into the riverbed high steep slope bed rock, the drilling efficiency is high, the effect is good, the construction period of the impervious wall is shortened, and the quality of the impervious wall is improved.
本发明公开了一种超深防渗墙成槽方法，包括对遇到防渗墙需嵌入河床高陡坡基岩内的情况采用复合爆破的方法形成槽孔：利用第一钻具对河床陡坡进行钻进，以形成穿过覆盖层至基岩陡坡斜面的钻孔；通过钻孔下设第一爆破装置并将其定位于陡坡斜面上，以利用第一爆破装置将陡坡斜面爆破成平缓斜面；利用第二钻具对平缓斜面以下的基岩继续钻进形成爆破孔，并通过安置在爆破孔内的第二爆破装置爆破平缓斜面以下的基岩；利用第三钻具继续对爆破后的基岩进行破碎与钻进处理，直至形成终孔。本发明的方法，可在施工条件恶劣的条件下对超深防渗墙成槽施工，使防渗墙嵌入河床高陡坡基岩内，且钻进效率高、效果好，缩短防渗墙施工工期，提高防渗墙质量。
