本发明涉及一种锚杆设备，确切地说是一种复合空心锚杆结构。
 背景技术
在锚杆是当前矿山、山体等支护系统中主要的定位设备，使用量巨大，但在实际使用中发现，当前的锚杆设备往往采用的实心杆体结构及空心杆体结构，虽然可以满足使用的需要，但也造成了在相同体积和自重条件下，当前锚杆设备均不同程度存在结构强度小、抗形变能力、抗剪应力均相对较差，从而导致当前锚杆使用的可靠性和稳定性均相对较差，于此同时，当前在通过锚杆进行支护作业时，由于作业面条件等因素，往往导致安装锚杆的锚孔深度差别相对较大，而当前的锚杆均采用的一体式结构，因此无法有效根据锚孔深度灵活调整锚杆的长度，从而导致锚杆使用时的灵活性和环境适应能力相对较差，切当锚杆较长时，也易导致锚杆结构强度受损，进一步影响了锚杆设备使用的稳定性和可靠性，因此针对这一问题，迫切需要开发一种发明的锚杆结构，以满足实际使用的需要。
