Empty pile backfill reinforcement construction method for cast-in-situ bored pile
The invention discloses an empty pile backfill reinforcement construction method for a cast-in-situ bored pile, which comprises the following steps of: 1, determining a pile core area, namely an empty pile, of the cast-in-situ bored pile to be treated, and dividing the pile core area into a main influence area, a secondary influence area and a non-influence area according to the additional load distribution of a foundation soil body; 2, engineering slurry in the pile core is reinforced, and a flocculation solidification filling area is formed in the non-influence area; 3, preparing a first pile core solidified soil material and a second pile core solidified soil material according to the load requirements in the main influence area and the secondary influence area; 4, backfilling the first pile core solidified soil material into the secondary influence area to form a first high-strength solidified filler filling area; 5, the second pile core solidified soil material is backfilled into the main influence area, and a second high-strength solidified filler filling area is formed; and 6, maintaining, wherein protective fences are arranged around the pile foundations. The invention relates to the technical field of building construction, and can solve the problem that a traditional backfill material cannot meet the requirement of foundation bearing capacity in the prior art.
本发明公开了一种钻孔灌注桩的空桩回填加固施工方法，包括步骤：1、确定需处理的钻孔灌注桩的桩芯区域即空桩，根据地基土体的附加荷载分布将桩芯区域分为主要影响区、次要影响区和无影响区；2、加固桩芯内工程泥浆，在无影响区内形成絮凝固化填充区；3、根据主要影响区和次要影响区内的荷载要求，制备第一桩芯固化土材料和第二桩芯固化土材料；4、第一桩芯固化土材料回填至次要影响区内，形成第一高强度固化填料填充区；5、第二桩芯固化土材料回填至主要影响区内，形成第二高强度固化填料填充区；6、养护，在桩基四周设置防护围栏。本发明涉及建筑施工技术领域，能解决现有技术中传统回填材料无法满足地基承载力要求的问题。
