本实用新型涉及一种应用于隧道快速钻机的超前地质预报装置。The utility model relates to an advanced geological prediction device applied to a tunnel fast drilling machine.
背景技术Background technique
随着我国国民经济的高速发展，特别是基础设施(高速铁路、高速公路)建设得到了突飞猛进的发展，隧道施工的要求更加快速高效，其工作量和工作难度都大大增加。快速钻机在目前的隧道施工中的使用越来越普及，但是现有的快速钻机并不能在快速钻进的过程中同时完成对前方地质情况的准确分析和判断，不具有超前地质预报分析的功能。With the rapid development of my country's national economy, especially the rapid development of infrastructure (high-speed railway, expressway) construction, the requirements for tunnel construction are faster and more efficient, and the workload and difficulty of the work are greatly increased. The use of fast drilling rigs in the current tunnel construction is becoming more and more popular, but the existing fast drilling rigs cannot complete the accurate analysis and judgment of the geological conditions ahead during the rapid drilling process, and do not have the function of advanced geological forecast analysis .
在隧道施工中常常遇到长度达数公里或数十公里的大隧道，虽然在前期的勘探设计过程中都进行过相应的地质勘探工作，对施工有一定的指导意义，但由于岩体的复杂性，使得勘察所获得的数据资料与隧道开完后所揭示出来的真实情况往往有较大的偏差。这样在隧道的施工过程中就会有很大的盲目性，施工过程中经常出现难以预料的塌方、冒顶、涌水等事故。而发生事故时，往往造成巨大的设备和财产损失，甚至人员伤亡，而且处理事故的难度往往较大，因此做好超前地质预报是隧道工程建设过程中一项十分重要而有益的工作。目前虽然已有很多的物探法存在，但是仍然不能很好地实现对隧道掌子面深部异常地质情况以及其具体深度位置的准确预报。In tunnel construction, large tunnels with a length of several kilometers or tens of kilometers are often encountered. Although the corresponding geological exploration work has been carried out in the previous exploration and design process, which has certain guiding significance for the construction, due to the complexity of the rock mass Due to the nature of the tunnel, there is often a large deviation between the data obtained by the survey and the real situation revealed after the tunnel is opened. In this way, there will be a lot of blindness in the construction process of the tunnel, and unexpected accidents such as landslides, roof falls, and water gushing often occur during the construction process. When an accident occurs, it often causes huge equipment and property losses, and even casualties, and it is often difficult to deal with the accident. Therefore, it is very important and beneficial to do a good job in advanced geological forecasting in the process of tunnel construction. Although there are many geophysical prospecting methods, they still cannot accurately predict the abnormal geological conditions in the deep part of the tunnel face and its specific depth position.
