Construction method of deep foundation pit sandy soil slope pile foundation bearing platform
The invention provides a construction method of a deep foundation pit sandy soil slope pile foundation bearing platform, and belongs to the technical field of bearing platform construction.The construction method comprises the following steps that the bearing platform is excavated, and after the bearing platform is excavated, expanding excavation is conducted on a sandy soil slope surface; the molding module is placed on the bearing platform, and a gap is reserved between the molding module and the slope surface of the sandy soil; gaps are backfilled, after the molding module is fixed, the reserved gaps are backfilled, the backfilled portions are tamped, a stable face is formed on the slope face of the sandy soil, the structure is stable, collapse is prevented, the molding module is removed, and concrete is poured into the bearing platform; according to the construction method of the deep foundation pit sandy soil slope pile foundation bearing platform, the molding module can be reused, the problem that in the prior art, when the bearing platform is poured, a foundation tire film is poured together is solved, and the construction cost is reduced.
本发明提供一种深基坑砂性土质斜坡桩基承台的施工方法，属于承台施工技术领域，包括以下步骤：承台开挖，承台开挖完成后，在砂性土质的斜坡面扩挖；塑型模块放置于承台上，所述塑型模块与砂性土质的斜坡面之间预留空隙；空隙回填，所述塑型模块固定后，对预留的空隙进行回填，对回填部位进行夯实，在砂性土质的斜坡面上形成稳固面，使结构稳定，预防坍塌，将所述塑型模块移除，承台内浇筑混凝土；本发明提供的深基坑砂性土质斜坡桩基承台的施工方法，所述塑型模块可以重复利用，解决了现有技术中承台浇筑时基础胎膜被一同浇筑的问题，降低了施工成本。
