技术领域technical field
本发明属于岩土、矿业工程技术领域,特别是涉及一种钻孔埋入式传感器安装固定与回收一体化装置。The invention belongs to the technical field of geotechnical and mining engineering, in particular to an integrated device for installation, fixation and recovery of a borehole buried sensor.
背景技术Background technique
岩土、矿业工程主要指的是一些边坡、隧道及矿山等建设工程,在进行隧道或矿山的建设时,工程扰动等外界因素可能导致隧道或矿山产生变形位移甚至坍塌,因此需要对相关部位进行实时微震监测,此时就需要在岩壁内钻孔并将传感器固定其中,以满足实时微震监测需要。然而,在安装钻孔埋入式传感器时,传统方式下都是利用粘性材料来固定传感器的,一旦钻孔与水平面具有夹角,导致传感器受重力作用影响较严重,粘性材料的固定效果并不理想,由于粘结不牢,极易造成传感器的脱落,降低数据采集的准确度。此外,对于已经粘结固定在钻孔内的传感器来说,无法实现传感器的回收,使用后只能遗弃在钻孔内,从而增加了监测成本。Geotechnical and mining engineering mainly refer to some construction projects such as slopes, tunnels and mines. During the construction of tunnels or mines, external factors such as engineering disturbances may cause deformation, displacement or even collapse of the tunnels or mines. For real-time microseismic monitoring, it is necessary to drill holes in the rock wall and fix the sensor in it to meet the needs of real-time microseismic monitoring. However, when installing a borehole embedded sensor, the traditional method is to use viscous material to fix the sensor. Once the drilled hole has an angle with the horizontal plane, the sensor is seriously affected by gravity, and the fixing effect of the viscous material is not good. Ideally, due to the weak bonding, it is easy to cause the sensor to fall off and reduce the accuracy of data acquisition. In addition, for the sensors that have been glued and fixed in the borehole, the sensor cannot be recycled, and can only be abandoned in the borehole after use, thereby increasing the monitoring cost.

下面结合附图说明本发明的一次使用过程:Describe one use process of the present invention below in conjunction with accompanying drawing:
当岩壁内完成钻孔加工后,首先将选定的传感器1插入传感器限位套筒3内,在插装传感器1的过程中,需要将传感器1的数据线从传感器限位套筒3的数据线穿线孔5中穿出,当传感器1固定好后,将传感器1朝内并把传感器安置段I和锚固段II完全插入岩壁钻孔内,只有握持调控段III留在钻孔外,同时保证传感器1的数据线也延伸至孔外。When the drilling process is completed in the rock wall, first insert the
当传感器1插入钻孔后,对于留在钻孔外的握持调控段III来说,需要一只手握住握持圆筒14的底端,另一只手握住调控螺母16,然后旋拧调控螺母16,使调控螺母16沿着轴向向下移动,移动的调控螺母16会通过传力套管19带动导向限位凸块18沿着导向槽孔17同步向下移动。After the
随着导向限位凸块18在导向槽孔17向下移动,会依次带动导向架15、传力衔接杆21、传力杆7及传力台8同步向下移动,随着传力台8的移动,会导致复位弹簧10被拉长而积蓄弹簧力。同时,随着传力台8的移动,传力台8圆锥面会对导向滑槽12上的导向滑块13产生径向挤压力,迫使导向滑块13在导向滑槽12上产生相对滑移运动的同时还会产生径向位移,随着导向滑块13的径向位移,会推动锚钉9沿着锚钉穿出孔11向外移动,直到锚钉9的钉尖穿出锚固支撑筒6并扎在钻孔孔壁上,直到调控螺母16旋不动为止,此时锚钉9可以牢固的扎在钻孔孔壁上,实现了装置的固定,传感器1便随着装置同步完成在孔内的安装固定。As the
当传感器1完成使用后,需要对传感器1进行回收,此时需要反向旋拧调控螺母16,使调控螺母16沿着轴向向上移动,随着调控螺母16的移动,调控螺母16对导向限位凸块18的推挤力则同步卸载,此时复位弹簧10的弹簧力开始作用,复位弹簧10逐级释放弹簧力并逐渐缩短复位,同时产生对传力台8向上的拉力,在拉力作用下,会依次带动传力台8、传力杆7、传力衔接杆21及导向架15向上移动,随着导向架15的移动,导向限位凸块18会沿着导向槽孔17同步向上移动,使导向限位凸块18、传力套管19和调控螺母16始终贴靠在一起。After the
随着传力台8的上移,传力台8圆锥面会对导向滑槽12上的导向滑块13产生径向拉拽力,迫使导向滑块13在导向滑槽12上产生相对滑移运动的同时产生径向位移,随着导向滑块13的径向位移,会拉动锚钉9沿着锚钉穿出孔11向内移动,使锚钉9与钻孔孔壁分离,直到锚钉9完全回缩到锚钉穿出孔11内,此时便完成了装置锚固状态的解除,之后就可以将装置整体从钻孔中拔出,最后将传感器1从传感器限位套筒3上拆下备用即可,直到下一次使用再重新安装,从而实现了传感器1的回收。With the upward movement of the
