Description
Technical Field
The utility model relates to an installation device suitable for even encircle tunnel lock foot stock location anchor.
Background
The Han tunnel belongs to a multi-arch tunnel and is positioned near Han village under bridge town. Mileage at the entrance and exit of the tunnel: k28+ 565-K29 +000, full length 435m, belongs to short tunnel. The maximum buried depth of the tunnel is about 47 m. The clear width/clear height of the tunnel is 2 x 11.5/5.0m, the longitudinal slope is a herringbone slope, the slope rate is + 2.8%, -2.75%, the inlet adopts an end wall type tunnel door, and the outlet is a bias type end wall tunnel door. The tunnel is the key and difficult point controllability project of the project.
Korean port tunnel entrance and exit end, exit hole are located the slope, and the entrance and exit hole is one section and stroke chemical rock road bed, because of exit hole is close to the temple, enters the entrance hole and is close to public house of highway, need adopt static blasting excavation rear can carry out the entrance hole and brush the slope. According to geological characteristics such as shallow burying, bias pressure and the like of a cave opening, the geology is complex, a three-pilot tunnel method is adopted for excavating holes, the middle partition wall is poured after the two ends of the middle pilot tunnel are tunneled and run through, the main tunnel is excavated by a side wall pilot tunnel method, the safety of the construction process of the cave opening section is ensured, and the safety is ensured to normally cross over a broken complex geological structure section so as to reduce the construction safety risk. The Korea tunnel is a multi-arch tunnel, the geological conditions of the opening are poor, the construction period is long, the surrounding environment is complex and other adverse factors affect the Korea tunnel, and particularly the opening section enters the hole and is under great pressure on construction difficulty, construction safety risk, construction period and construction cost. Therefore, a large number of anchor rods are used for arching the lining in the opening.
Before the foot-locking anchor rod is mainly used for lining construction of a railway tunnel by a first arch and then wall method, before a lower section is excavated, 1-2 rows of anchor rods are driven in a manner that arch springing is vertical to a rock wall so as to prevent the arch springing from contracting and falling off an arch; when the side wall advanced anchor rod is excavated by a bench method, the upper bench excavation support is completed, before the lower section of the excavation, the anchor rod is driven downwards in an inclined way at the arch springing, so that the arch springing can be stabilized, and the lower part excavation can be supported in advance. Recently, since the arch-first wall-second method lining has not been adopted, the side wall leading anchor has been called a locking pin anchor. The function of the locking pin anchor rod is as follows: 1. the suspension function of the anchor rod: the anchor rod penetrates through soft, loose and unstable rock-soil bodies and is anchored on the deep and stable rock-soil bodies to provide enough tension, so that the dead weight and the gliding force of the gliding rock-soil bodies are overcome, and the slippage and the collapse of the tunnel wall are prevented. 2. And (3) extrusion and reinforcement effects: after the anchor rod is stressed, a compression area is formed in a certain range around the anchor rod. The anchor rod sheets are arranged in a proper mode, so that compression areas formed by the adjacent anchor rods are mutually overlapped to form compression bands. The loose stratum in the compression band is reinforced through the anchor rod, and the wholeness reinforcing, bearing capacity improve.
