Foundation treatment construction technology under backfilling or hydraulic reclamation land forming condition
The invention provides a foundation treatment construction process under a backfill or hydraulic reclamation land formation condition, which is used for a building area and comprises the following steps: digging a drainage ditch on a foundation with a cleaned surface layer, arranging a plastic drainage plate in a soil body with the depth of 13m-19m to form a drainage consolidation channel in the deep soil body, and forming a drainage consolidation channel in the soil body with the depth of 13m-19m; a soil body drainage consolidation area is formed between the plastic drainage plate and the deep soil body and is used for reinforcing the soil body drainage consolidation area; the method further comprises the steps that in the foundations with the depth larger than or equal to 2.5 m on the two sides of the soil body drainage consolidation area, well point dewatering dynamic compaction is conducted on the foundations in an open trench or open trench and light well point combined dewatering and drainage mode, well pipes with the filtering function are arranged at the positions staggered with the walking route of a tamping machine and in drainage ditches, well point dewatering is conducted through the well pipes, and the soil body drainage consolidation area is constructed. And finally, dewatering dynamic compaction is selected in a non-building area, and foundation treatment is completed in the building area in the mode of combination of extension socket and dewatering dynamic compaction. According to the invention, pore water pressure generated during dynamic compaction can be quickly dissipated, so that a soil body is quickly consolidated.
本发明提供了回填或吹填成陆条件下的地基处理施工工艺，用于建筑区域，包括以下步骤，于表层清理后的地基上，开挖排水沟，于13m~19m深的土体中，打设塑料排水板使其在深层土体中形成排水固结通道，所述塑料排水板与深层土体之间形成土体排水固结区域并对其进行加固；还包括在所述土体排水固结区域两侧，且深度大于等于2.5m的地基内，以明沟或明沟结合轻型井点的降排水方式，进行井点降水强夯地基，在与夯机行走路线错位的位置处，于排水沟内设置带有过滤功能的井管，利用井管施工井点降水，最后非建筑区选用降水强夯，建筑区选用插排结合降水强夯的方式，分别完成地基处理。本发明能够快速消散消散强夯时产生的孔隙水压力，使得土体快速固结。
