Foundation pit backfilling method in pile foundation underpinning construction
The invention discloses a foundation pit backfilling method in pile foundation underpinning construction. The foundation pit backfilling method comprises the following steps of after the constructionof a pile foundation underpinning structure is completed in a foundation pit, cleaning loose impurities at the bottom of the foundation pit, backfilling and paving earthwork to the bottom of the foundation pit to form a backfilling soil layer with the thickness of 200-250mm, then tamping the backfilling soil layer to form a tamped layer, and finally are constructing one or more tamped layers in sequence according to the method till the foundation pit is filled with the tamped layers. By adopting the foundation pit backfilling method in pile foundation underpinning construction, the backfillingcompactness can be improved, the influence on the pile foundation underpinning structure is small, the construction safety can be improved, the stability of the pile foundation underpinning structureis improved, and the pile foundation underpinning construction quality is improved.
本发明公开了一种桩基托换施工中的基坑回填方法，该基坑回填方法在基坑内完成桩基托换结构的施工后，将基坑底的松散杂质清理干净，再将土方回填摊铺到基坑底部形成一层厚度为200mm～250mm的回填土层，然后将该层回填土层夯实形成一层夯实层，最后按照该方法再依次施工一层以上夯实层，直至将基坑填满。采用该基坑回填方法可提高回填密实度，对桩基托换结构影响小，可提高施工安全性、提高桩基托换结构的稳定性、提高桩基托换施工质量。
