Differential deformation construction control method and system for high-filled high-speed railway roadbed
The invention discloses a high-filled high-speed rail roadbed differential deformation construction control method which comprises the following steps: S1, drilling a roadbed layer downwards to obtain a permeable drill hole; s2, the permeable drill holes are backfilled with rock ballast until the rock ballast is backfilled to a preset position, water is poured into the permeable drill holes, and after the rock ballast naturally settles, the rock ballast continues to be backfilled to form a filling section; s3, concrete is continuously backfilled into the water-permeable drill hole, a reinforcing section is formed, and the periphery of the reinforcing section is surrounded by a rock layer; s4, after the concrete is solidified, a hole is drilled in the solidified concrete surface, an anchor rod is inserted into the drilled hole and anchored to the solidified concrete and the rock layer, and the upper end of the anchor rod is exposed out of the solidified concrete surface; s5, the solidified concrete surface is continuously backfilled with concrete till the solidified concrete surface is flush with the road surface, and a connecting section is formed. According to the construction method, the filling section, the reinforcing section and the connecting section are formed by backfilling the water-permeable drill hole with mountain cutting rock ballast and concrete, the foundation stability can be enhanced while the cost is reduced, and the precise deformation condition of the foundation can be well controlled.
本发明公开了一种高填高铁路基差异变形施工控制方法，包括以下步骤：S1、在路基层向下钻孔，得到透水钻孔；S2、向透水钻孔内回填石渣，直至回填至预设位置，向其中灌注水，待石渣自然沉降之后，再继续回填石渣，形成填充段；S3、继续向透水钻孔内回填混凝土，形成加固段，加固段外围环绕有岩石层；S4、待混凝土固化之后，在固化的混凝土面钻孔，并将锚杆插入钻孔内，并锚固于固化混凝土和岩石层上，并使得锚杆上端露出固化混凝土面；S5、继续向固化混凝土面回填混凝土直至与路面持平，形成连接段，本发明通过向透水钻孔中回填开山石渣、混凝土，形成填充段、加固段以及连接段，在降低成本的同时可以加强地基稳固，很好的控制地精形变情况。
