Reinforcing method for shield tunneling machine to laterally penetrate through power transmission line iron tower
The invention relates to the technical field of shield tunnel construction, and discloses a reinforcing method for a shield tunneling machine to laterally penetrate through a power transmission line iron tower, which comprises the following steps: S1, preparing for construction, and breaking a road surface; s2, measuring the pile position according to the position of the power transmission line iron tower, and positioning and paying off; s3, concrete is poured on the two sides of the tops of the pile positions to form guide walls; s4, drilling secant pile construction is started, plain piles without reinforcement cages on the two sides are constructed firstly, and then reinforced piles with reinforcement cages in the middles are constructed; s5, in-pile waist bars at the tops of the drilling secant piles are used for pouring concrete to form a top beam, and all pile foundations are connected together; and S6, earthwork backfilling is conducted. According to the method, the tower footing of the power transmission line iron tower and the surrounding stratum can be reinforced.
本发明涉及盾构隧道施工技术领域，公开了一种盾构机侧穿输电线路铁塔的加固方法，包括以下步骤：S1施工准备、破除路面；S2根据输电线路铁塔的位置对桩位进行测量，定位放线；S3在桩位顶部两侧浇灌混凝土形成导墙；S4开始钻孔咬合桩施工，先施工两侧无钢筋笼的素桩，再施工中间有钢筋笼的荤桩；S5利用钻孔咬合桩顶部的桩内腰筋浇筑混凝土形成冠梁，将所有的桩基连在一起；S6进行土方回填。本发明能够对输电线路铁塔塔基以及周围的地层都进行了加固。
