Construction method for preventing settlement during pipeline burying in collapsible loess area
The invention discloses a collapsible loess area pipeline burying settlement prevention construction method which comprises the following construction steps that S1, the range of a collapsible loess area is known through a geological exploration report, a groove is excavated, and then a grouting support is placed at the bottom of the groove; s2, a drill rod is used for drilling an anchor hole of a support anchor lug of the grouting support, and the drill rod is taken out after hole forming; s3, a first section of hollow guide pipe is inserted, and grouting equipment is connected to the top; s4, high-strength cement paste is injected in a pressurized mode, so that soil at the bottom of the groove forms a whole; s5, pipeline laying; and S6, pipeline backfilling is conducted, specifically, the collapsible loess area range is known through a geological exploration report, then a grouting support is placed at the bottom of the groove, a drill rod is used for being aligned with an anchor hole of a support anchor lug of the grouting support for drilling, after hole forming, the drill rod is taken out, a first hollow guide pipe is inserted, grouting equipment is connected to the top of the first hollow guide pipe, high-strength cement paste is injected in a pressurized mode, and grouting is conducted. Soil at the bottom of the groove is formed into a whole, collapsibility is eliminated, and then pipeline laying is conducted.
本发明公开了一种湿陷性黄土区域管道埋设防止沉降施工方法，包括以下施工步骤：S1：通过地勘报告了解湿陷性黄土区域范围，进行沟槽开挖，然后在沟槽底部安放灌浆支座；S2：使用钻杆对准灌浆支座的支座锚耳的锚孔进行钻孔，成孔后取出钻杆；S3：插入第一节空心导管，并在顶部接入灌浆设备；S4：加压灌入高强度水泥浆，使沟槽底部土质形成整体；S5：管道铺设；S6：管道回填，通过地勘报告了解湿陷性黄土区域范围，然后在沟槽底部安放灌浆支座，使用钻杆对准灌浆支座的支座锚耳的锚孔进行钻孔，成孔后取出钻杆，插入第一节空心导管，在第一节空心导管顶部接入灌浆设备，加压灌入高强度水泥浆，使沟槽底部土质形成整体消除湿陷性，在进行管道铺设。
