Method and structure for improving natural foundation bearing capacity
The invention provides a method and structure for improving the bearing capacity of a natural foundation. The structure comprises a foundation groove, a first supporting layer and a second supportinglayer, wherein the foundation groove is dug in the natural foundation, the first supporting layer is laid on the inner bottom surface of the foundation groove, the first supporting layer makes contactwith a soft underlying layer, the second supporting layer is arranged in the foundation groove, the first supporting layer and the second supporting layer are connected into a whole, the sectional area of the first supporting layer is larger than that of the second supporting layer, and the first supporting layer and the second supporting layer are manufactured through concrete pouring. The method and structure for improving the natural foundation bearing capacity has the beneficial effects that by arranging the first supporting layer and the second supporting layer which are formed by pouring the concrete, the bearing capacity of the natural foundation is greatly improved, and have the following advantages that 1, the problem of repeated soil backfilling is solved; 2, the use of a dynamic compactor is greatly reduced, and the construction cost is reduced; 3, the construction period is shortened, and the process requirements are improved; and 4, the construction efficiency is improved.
本发明提出了一种改善天然地基承载力的方法及结构，包括：地基槽、第一持力层和第二持力层，在天然地基上开挖所述地基槽，第一持力层铺设在所述地基槽的内底面上，且所述第一持力层与软弱下卧层接触；第二持力层设置在所述地基槽内，且所述第一持力层与所述第二持力层连接为一体，所述第一持力层的截面积大于所述第二持力层的截面积，所述第一持力层和第二持力层通过混凝土浇筑制成。本发明的有益效果在于，通过设置混凝土浇筑的第一持力层和第二持力层，极大地改善了天然地基承载力，具有以下优点：1、解决反复回填土的问题。2、大量减少了强夯机的使用，减少了施工费用3、降低了工期，提高了工艺要求。5、施工效率得到提高。
