Embodiment Construction
[0035] refer to Figure 1 to Figure 9 , the present invention is a kind of preprocessing method of the anchor cable group passing through the shield tunneling section, comprising the following steps:
[0036] 1), the layout of the artificial well 3 and the overall idea of excavation.
[0037] Collect the design and construction data of the anchor cable 1 passing through the excavation section of the shield tunnel, that is, the shield path 2, determine the hole position according to the construction drawing of the anchor cable 1, and conduct a test hole before the full-scale construction, and initially determine the anchor cable 1 s position. The artificial well 3 is arranged on the side away from the end of the anchor cable 1, from figure 1 Seen from above, the artificial well hole 3 is arranged on the side of the invasion start point, which is convenient for pulling out after cutting the anchor cable 1 .
[0038] The artificial well 3 adopts the excavation method of jump...
