Construction method of rapid and non-excavation underground pipeline cover plate protection structure
The invention belongs to the technical field of underground structures, and particularly relates to a rapid and non-excavation underground pipeline cover plate protection structure construction method. The underground pipeline cover plate protection structure comprises a plurality of steel pipe sleeves, a prefabricated cover plate and anti-seepage double-layer geotechnical cloth filled with high-compressibility granular materials. The steel pipe sleeves are vertically arranged on the two sides of the pipeline and serve as supporting foundations of the prefabricated pipeline cover plate. A tenon is arranged on the lower side of the prefabricated pipeline cover plate and embedded into an upper opening of the steel pipe sleeve to fix the position; the double-layer geotechnical cloth is laid between the steel pipe sleeves on the two sides of the pipeline and used for fixing and preventing running and leakage. The construction comprises field geological exploration and field pressure test, and the bearing capacity, the specific length, the spacing and the number of the steel pipe sleeves are calculated; prefabricating a cover plate, and determining the position and the size of a tenon on the lower side of the cover plate according to the number and the distance of the steel pipe sleeves; construction is convenient, the working face and the work amount can be greatly reduced, and construction time is shortened; and meanwhile, the pipeline safety can be effectively protected.
本发明属于地下构筑物技术领域，具体涉及一种快速、非开挖地下管线盖板保护结构施工方法。本发明设计的地下管线盖板保护结构包括若干根钢管套筒、预制盖板以及填充高压缩性颗粒材料的防渗双层土工布；钢管套筒竖向布设于管线两侧，作为预制管线盖板的支撑基础；预制管线盖板的下侧设置凸隼，嵌入钢管套筒上口中以固定位置；双层土工布铺设于管线两侧的钢管套筒之间、用于固定和防止跑、漏。施工包括现场地勘及现场压力试验，计算钢管套筒的承载力及具体长度、间距、数量；预制盖板，根据钢管套筒的数量、间距，确定盖板下侧的凸隼位置、尺寸大小；施工方便，可大大减少作业面和工程量，缩短施工时间；同时可有效保护管线安全。
