Structure for improving horizontal bearing capacity of reinforced concrete cast-in-place piles
The invention discloses a structure for improving the horizontal bearing capacity of reinforced concrete cast-in-place piles, and belongs to the technical field of building structures. According to the structure, a new cross beam is additionally arranged below an original bearing table beam of two foundation piles, the two ends of the new cross beam and the two foundation piles are subjected to cast-in-place forming through reinforced concrete correspondingly, the horizontal height and the sectional dimension of the new cross beam are determined according to calculation and the structure requirements, and the tops of the foundation piles are restrained to be fixedly connected through the new cross beam and the original bearing table beam. The problems that in practical engineering, the detected foundation pile horizontal bearing capacity is smaller than the designed bearing capacity, and the burial depth of a bearing table cannot be increased or batter piles cannot be additionally arranged can be solved.
本发明公开了一种增加钢筋混凝土灌注桩水平承载力的构造，属于建筑结构技术领域。该构造是在两根基桩的原承台梁下方增加一道新横梁，新横梁的两端分别与两根基桩采用钢筋混凝土现浇成型，新横梁的水平高度及截面尺寸根据计算和构造要求确定，通过新横梁与原承台梁使基桩顶部约束形成固接。本发明能够解决实际工程中检测出来的基桩水平承载力小于设计承载力，而又无法增加承台埋深或增设斜桩的问题。
