Description

一种前置式支护掘进机结构及工作方法A front-mounted supporting tunnel boring machine structure and working method 技术领域Technical field
本发明涉及隧道掘进机设备领域，特别是一种前置式支护掘进机结构及工作方法。The invention relates to the field of tunnel boring machine equipment, in particular to a front-mounted supporting boring machine structure and working method.
背景技术Background technique
隧道掘进机是一种集掘进、出渣、导向、支护和通风防尘等多功能为一体的大型高效隧道施工机械，基本工作原理是支撑靴撑紧围岩以提供刀盘掘进所需的推力和刀盘旋转所需的扭矩，刀盘切入岩石，切削岩渣靠自重经溜渣槽落入皮带机出渣，这样连续掘进成洞；刀盘后面设置有护盾，护盾内装有驱动电机等***；护盾后装有隧道围岩支护组件，包括钢拱架、锚杆安装机、初衬混凝土喷射机等，起到对围岩开挖面的支持维护作用。The tunnel boring machine is a large-scale and efficient tunnel construction machine that integrates the functions of excavation, slag discharging, guidance, support, ventilation and dust prevention. The basic working principle is that the support shoes hold the surrounding rock tightly to provide the necessary force for the cutterhead excavation. The thrust and the torque required for the rotation of the cutterhead, the cutterhead cuts into the rock, and the cut rock slag falls into the belt conveyor through the slag chute by its own weight, and the hole is continuously dug into the hole; there is a shield behind the cutterhead, and a driver is installed in the shield Motor and other systems; the tunnel surrounding rock support components are installed behind the shield, including steel arch frames, anchor installation machines, primary lining concrete spraying machines, etc., which play a role in supporting and maintaining the surrounding rock excavation surface.
采用传统结构隧道掘进机开挖破碎岩层或软弱岩层时，由于隧道岩层被挖空，内部应力迅速释放且未得到及时支护，导致围岩发生快速且较大变形；当围岩变形过大时，围岩会完全包裹住盾壳，当包裹力大于掘进机推力极限时，导致围岩卡机事故。目前，隧道掘进机卡机是极难处理的工程现场问题，甚至导致掘进机报废，隧道不得不更改线路。因此，掘进机施工过程中应避免卡机事故。目前，针对掘进机开挖破碎岩层或软弱岩层防卡机措施十分有限，一般采用盾壳后的超前管棚注浆设备，沿盾壳上侧沿一定角度超前打设管棚，将破碎岩层或软弱岩层提前注浆加固，该措施耗时较长，且需要消耗大量的浆液和钢管。When a tunnel boring machine with a traditional structure is used to excavate broken rock or weak rock, because the tunnel rock is hollowed out, the internal stress is quickly released without timely support, resulting in rapid and large deformation of the surrounding rock; when the deformation of the surrounding rock is too large, , the surrounding rock will completely wrap the shield shell. When the wrapping force is greater than the thrust limit of the tunnel boring machine, it will cause the machine to jam in the surrounding rock. Currently, tunnel boring machine jamming is an extremely difficult project site problem to deal with, and may even lead to the scrapping of the tunnel boring machine and the tunnel having to be rerouted. Therefore, machine jamming accidents should be avoided during tunnel boring machine construction. At present, there are very limited anti-jamming measures for tunnel boring machines excavating broken rock strata or weak rock strata. Generally, advanced pipe shed grouting equipment behind the shield shell is used. Weak rock formations are reinforced with grouting in advance. This measure takes a long time and requires a large amount of grout and steel pipes.
现阶段，山岭隧道破碎岩层或软弱岩层的掘隧道进机施工仍然是行业的重大难题之一。受限于传统掘进机结构，支护组件位于盾壳后方，无法实现对裸露围岩的及时跟进支护，导致隧道围岩悬空变形过大。At this stage, the tunnel boring machine construction of broken rock strata or weak rock strata in mountain tunnels is still one of the major problems in the industry. Limited by the traditional tunnel boring machine structure, the support components are located behind the shield shell, which makes it impossible to implement timely follow-up support of the exposed surrounding rock, resulting in excessive suspended deformation of the tunnel surrounding rock.
技术问题technical problem
申请人认为，为了防止破碎岩层或软弱岩层的过大变形，阻止卡机事故发生，可以充分利用刀盘后方盾壳内侧未使用空间，合理布设支护组件，当刀盘掘进破岩后围岩出露后，该部位的支护组件可以及时支撑围岩，有效阻止围岩的变形，这也就阻止了围岩大变形引起的卡机事故。与此同时，在刀盘后方盾壳内侧未使用空间内布设支护组件，可以有效利用盾构空间，达到结构紧凑，防止岩渣进入主机***，增大了掘进机的使用寿命。The applicant believes that in order to prevent excessive deformation of broken rock strata or weak rock strata and prevent machine jamming accidents, the unused space on the inside of the shield shell behind the cutter head can be fully utilized, and support components can be reasonably arranged. When the cutter head digs into the broken rock, the surrounding rock After being exposed, the support components at this location can support the surrounding rock in time and effectively prevent the deformation of the surrounding rock. This also prevents machine jamming accidents caused by large deformation of the surrounding rock. At the same time, support components are arranged in the unused space on the inside of the shield shell behind the cutterhead, which can effectively utilize the shield space, achieve a compact structure, prevent rock slag from entering the host system, and increase the service life of the tunnel boring machine.
技术解决方案Technical solutions
本发明目的就是为了解决隧道掘进机开挖破碎岩层或软弱岩层过程中裸露围岩未及时支护导致的围岩大变形甚至卡机问题；同时，合理利用掘进机内部空间，达到结构紧凑，延长设备使用寿命。The purpose of the invention is to solve the problem of large deformation of the surrounding rock and even machine jamming caused by the failure of timely support of the exposed surrounding rock when the tunnel boring machine excavates broken rock strata or weak rock strata; at the same time, the internal space of the tunnel boring machine is reasonably utilized to achieve a compact structure and extended Equipment service life.
