The drilling rig has certain difficulty in drilling the weathered rock layer. At the moment, the casing process and the mud wall are not so important, the real problem is how How to increase the power to rock! We should also reduce the loss of drilling tools and drill teeth, and timely detect and protect drill pipes, and prevent deviating holes. 中風(fēng)化巖施工安全防止措施 Safety prevention measures for the construction of medium weathered rock 1、取巖芯 1. Taking core 中風(fēng)化強(qiáng)度較高,一般都選用筒鉆入巖取芯方法鉆進(jìn),相對(duì)于全斷面鉆斗,筒鉆入巖節(jié)約做工,可提升入巖能力,但一起也面對(duì)取巖芯幾率的問(wèn)題! The middle weathering intensity is high, and the core method is generally used to drill into the core method. Compared with the full section drill pipe, the cylinder drilling into the rock can save the workmanship and can improve the ability to enter the rock, but it also faces the problem of taking the core probability together. 防止措施:筒鉆取巖芯的幾率與巖石層理裂隙、單斗進(jìn)尺深度及鉆具結(jié)構(gòu)和鉆齒分布都有關(guān)聯(lián)。 Prevention measures: the probability of core drilling is related to rock bedding and crevice, depth of single bucket, drilling tool structure and drill tooth distribution.
