Construction method of drilled piles adjacent to operation railway
The embodiment of the invention provides a construction method of drilled piles adjacent to an operation railway. The construction method comprises the steps that the construction positions of the drilled piles are determined, specifically, the positions of the multiple columns of preset drilled piles are determined at intervals in the preset new project trend, and the positions of the preset drilled piles in each column are arranged at intervals; the first type of drilled pile construction is conducted, specifically, in the position of the column of preset drilled piles closest to the operation railway, a plurality of guard piles are driven into the periphery of the position of the preset drilled piles right facing a pier foundation of the operation railway, guard cylinder mounting operation is conducted in an area defined by the guard piles, and drilled pile construction is conducted in guard cylinders; and the second type of drilled pile construction is conducted, specifically, in the direction away from the operation railway, a plurality of guard piles are driven into the periphery of the remaining positions of the preset drilled piles column by column, and drilled pile construction is conducted in an area defined by the guard piles. According to the construction method, disturbance of drilled pile construction closest to the operation railway is reduced by burying the guard cylinders, and the influence on operation of the operation railway is reduced.
本发明实施例提供一种邻近运营铁路的钻孔桩的施工方法，该施工方法包括：确定钻孔桩施工位置：沿预设的新建工程走向间隔确定若干列预设钻孔桩位置，每列中的预设钻孔桩位置间隔布置；第一类钻孔桩施工：最靠近运营铁路的一列预设钻孔桩位置中，在正对运营铁路的桥墩基础的预设钻孔桩位置的周边打入若干个护桩，在护桩围设形成的区域内进行护筒安装作业，在护筒内进行钻孔桩施工；第二类钻孔桩施工：沿远离运营铁路的方向，逐列在剩余的预设钻孔桩位置的周边打入若干个护桩，在护桩围设形成的区域内进行钻孔桩施工。本发明实施例中的施工方法通过埋设护筒降低了最靠近运营铁路的钻孔桩施工对运营铁路所产生的扰动，降低了对运营铁路运营的影响。
