Excavation construction method for hard rock of manual hole digging pile adjacent to existing railway business line
The invention discloses a construction method for excavating hard rocks by manual hole digging piles adjacent to an existing railway business line. The construction method comprises the following steps: (1) physically isolating an adjacent railway side; (2) measuring and lofting: lofting according to the sideline of the hole digging pile; (3) excavating and constructing a fore shaft; (4) mounting and fixing the hoisting frame; (5) installing a rhinestone in place and constructing; (6) rock expansion cracking; and (7) block hoisting: firmly binding the block rock blocks by using a steel wire rope, and hoisting the rock blocks out of the hole by using a winch. And (8) circulating the steps (5)-(7) until the hole bottom elevation is designed. Compared with the prior art, foundation disturbance caused by blasting and safety of a railway business line can be effectively avoided, and compared with a handheld pneumatic pick, the pneumatic pick is higher in effect, lower in cost, safer and more reliable.
一种邻近既有铁路营业线人工挖孔桩坚硬岩开挖施工方法，包括如下步骤：①对邻近铁路侧进行物理隔离；②测量放样，按照挖孔桩边线放样；③锁口开挖及施工；④吊装架安装固定；⑤水钻安装就位、施工；⑥岩块涨裂；⑦分块吊装，将分块的岩块利用钢丝绳捆绑牢固，利用卷扬机将岩块吊装出孔内。⑧循环⑤～⑦步骤，直至设计孔底标高。与现有技术相比，本发明可有效避免因爆破造成的地基扰动及对铁路营业线的安全，相比较与手持风镐功效更高、成本更低，更为安全、可靠。
