Construction method for pile cap foundation in non-uniform backfill area
The invention discloses a non-uniform backfill area pile bearing platform foundation construction method, which relates to the technical field of building construction, and comprises the following steps: S1, determining the center position of a pile bearing platform foundation; s2, a cofferdam is built in the center position, the cofferdam is filled with plain soil so that the plain soil can be flush with the top of the cofferdam, then the plain soil is compacted, and an operation platform is formed; s3, a soft soil layer or a non-uniform soil layer in a certain range under the foundation ground is excavated out to form a foundation pit, a foundation pit slope is protected in a foundation pit supporting mode in the foundation pit construction process, and the safety of the foundation pit slope is guaranteed; the method has the beneficial effects that a non-uniform backfill area is treated by adopting measures such as digging out a soft soil layer within a certain range below the bottom surface of the foundation or replacing and filling a non-uniform soil layer, so that non-uniform settlement of the foundation is avoided; the foundation pit is protected in a supporting mode, the safety of a side slope on site is guaranteed, collapse, landslide and other dangerous conditions are not prone to occurring when the foundation pit is excavated in a non-uniform backfill area, and the construction progress is accelerated.
本发明公开了一种不均匀回填区桩承台基础施工方法，涉及建筑施工技术领域，包括以下步骤：S1：确定桩承载台基础中心位置；S2：在中心位置建造围堰，向围堰内部填充素土使其与围堰顶部平齐，再将其压实，形成作业平台；S3：挖除基础地面下一定范围内的软弱土层或者不均匀土层形成基坑，在基坑施工过程中对基坑边坡采用基坑支护的形式进行防护，保证基坑边坡安全；本发明的有益效果是：采用挖除基础底面下一定范围内的软弱土层或不均匀土层换填等措施对不均匀回填区域进行处理，以确保地基不出现不均匀沉降；通过对基坑采用支护形式进行防护，保证现场边坡安全，在不均匀回填区域基坑开挖时不易发生坍塌、滑坡等危险情况，加快施工进度。
