Description

Technical Field

[0001] The invention relates to the technical field of TBM engineering machinery, and in particular to a hard rock TBM normal anchor (cable) drilling rig and a construction method thereof. Background Art

[0002] Hard rock tunnel boring machines (TBMs) are widely used in tunnel (hole) construction in transportation, water conservancy, mining and other fields due to their advantages such as fast excavation speed, high construction quality and low environmental disturbance. Hard rock TBMs can be divided into open TBMs, single shield TBMs and double shield TBMs, among which open TBMs are the most widely used in my country and even in the world. For exposed surrounding rock (or tunnel wall), open TBMs generally adopt support measures such as steel arch frames, anchor net spraying, advanced pipe sheds, and advanced grouting to deal with the risks of surrounding rock convergence and collapse. However, when TBM encounters high-stress soft surrounding rock or fault fracture zones, untimely or inappropriate support can easily cause the exposed surrounding rock to collapse and become unstable. In severe cases, it may cause damage to equipment in the L1 area, casualties, and even cause the TBM to be trapped and stuck. The use of reasonable support methods can effectively improve the construction efficiency of TBMs and ensure the safety of TBM operations. Anchor (cable) support is one of the most effective means to deal with large deformation of surrounding rock convergence and establish a bearing arch in the loose circle of surrounding rock, and is widely used in tunnel (hole) projects.

[0003] However, current anchor (cable) drilling rigs (such as Figure 1 The following defects exist when driving anchors (cables): 1) It is impossible to drill holes and anchors (cables) vertically on the cave wall, and thus it is impossible to effectively apply high prestress of the anchors (cables); 2) The drilling range of holes and anchors (cables) is limited, generally not exceeding 180° of the arch top; 3) It is difficult for multiple (generally two) anchor (cable) drilling rigs to work independently to adapt to the convergence of the surrounding rock.

[0004] Therefore, it is urgent to design a hard rock TBM normal anchor (cable) drilling rig and its system, so that it can drill holes and anchors (cables) 360° vertically on the tunnel wall and achieve high prestressing. In addition, multiple anchor (cable) drilling rigs can work relatively independently according to the convergence of the surrounding rock to improve the support capacity and efficiency.

Step 2.5: The anchor / cable drilling machine injects grout into the gap between the anchor and the drill hole through the grouting pipe until the construction requirements are met; Step 2.6: The gasket fixing device makes the metal gasket of the anchor rod close to the hole wall, and the anchor rod / cable drilling machine pulls the anchor rod outward for a certain distance until the specified prestressing level is reached; Step 2.7: Repeat steps 2.1 to 2.6 until the anchor / cable drilling rig completes all anchor driving and prestressing as required by the construction. The anchor cable is driven toward the borehole under the rolling action of the roller at the end of the anchor rod / cable drilling machine guide rail. The steps of driving the anchor cable and applying prestress by the anchor rod / cable drilling machine are as follows: Step 3.1: The anchor / cable drilling machine is in the original position and is driven by the crawler trolley to move to the vicinity of the drill hole where the anchor cable is to be installed; Step 3.2: On-site workers insert the anchor cable into the roller at the end of the anchor rod / cable drilling rig guide rail. The end of the anchor cable has a metal gasket to apply prestress to the anchor cable; Step 3.3: The roller at the end of the anchor / cable drill guide rotates, and the anchor cable is gradually driven into the drill hole until it reaches the specified depth; Step 3.4: The anchor / cable drilling rig grouting pipe injects grout into the gap between the anchor cable and the drill hole until the construction requirements are met; Step 3.5: The gasket fixing device makes the anchor cable metal gasket close to the hole wall, and the roller at the end of the anchor rod / cable drilling rig guide rail is reversed to pull the anchor cable outward for a certain distance until the specified prestressing level is reached; Step 3.6: Repeat steps 3.1 to 3.5 until the anchor / cable drilling rig completes all anchor cable installation and prestressing according to construction requirements.
