Treatment method for settlement and displacement of high-grade highway subgrade and retaining wall
The invention relates to the field of highway construction, in particular to a treatment method for settlement and displacement of a high-grade highway roadbed and a retaining wall. Comprising the following steps: S1, dredging a drainage hole of a retaining wall; s2, filling the overlarge or damaged part of the settlement joint of the retaining wall with asphalt hemp ribs, and then filling coarse sand for repairing the overlarge or damaged part of the settlement joint of the retaining wall; s3, high-grade mortar is used for filling and repairing the cracked and damaged part of the retaining wall; s4, dredging the drainage system of the wall foot of the retaining wall, and backfilling the elevation position of the wall foot; s5, vertical micro piles are arranged on the sides, close to the roadbed, of the retaining walls, and the roadbed is reinforced through the vertical micro piles; s6, transverse micro piles are additionally arranged on the lower portion of the retaining wall, and the roadbed is reinforced through the transverse micro piles; s7, breaking and removing a water stable layer of the road section, and completely excavating and removing earth and stones within the range of the roadbed and the roadbed; s8, the roadbed of the road section is reinforced through heavy ramming till the designed repairing requirement is met; s9, a longitudinal blind ditch is additionally formed in the side, away from the retaining wall, of the roadbed, and accumulated water is drained through the longitudinal blind ditch; and S10, filling construction is conducted on the roadbed.
本发明为公路施工领域，是一种高等级公路路基及挡墙沉降、位移的处治方法。包括：S1、对挡墙的泄水孔进行疏通；S2、对于挡墙沉降缝过大或损坏处，通过沥青麻筋填塞后灌入粗砂修补；S3、对于挡墙开裂破损处，使用高标号砂浆进行填实修补；S4、疏通挡墙墙脚排水系统，对墙脚标高低位置进行回填；S5、在挡墙靠近路基的一侧设置竖向微型桩，通过竖向微型桩对路基加固；S6、在挡墙的下部增加横向微型桩，通过横向微型桩对路基加固；S7、将此路段水稳层破除，并将路基路床范围内土石方全部挖除；S8、采用重夯对此路段的路基进行补强加固，直至符合设计修补要求；S9、在路基上远离挡墙一侧增加纵向盲沟，通过纵向盲沟排出积水；S10、对路床进行填筑施工。
