Deep and shallow foundation pit construction structure and construction method
The invention discloses a deep and shallow foundation pit construction structure. The deep and shallow foundation pit construction structure comprises a deep foundation pit and a shallow foundation pit, a support pile is arranged between the deep foundation pit and the shallow foundation pit, a crown beam is fixedly arranged at the top of the support pile and is of an annular structure surrounding the deep foundation pit, a haunched beam is arranged on the side face, located on one side of the shallow foundation pit, of the crown beam, the longitudinal section of the haunched beam is of an inverted trapezoidal structure, and the haunched beam is used for tying the crown beam. The haunched beam is additionally arranged on the outer side of the crown beam, so that the stability of the supporting pile is effectively improved, the bearing capacity of the supporting pile is greatly improved, the supporting pile can meet the construction requirement that the shallow foundation pit is excavated firstly and then the deep foundation pit is excavated, and the construction efficiency and safety are greatly improved. A bottom plate, the haunched beam and the crown beam are firmly connected through a first upper rubber band, a second upper rubber band and a lower rubber band, the construction structure is further reinforced, the bearing capacity of the construction structure is effectively improved, and the method is simple, easy to operate and low in cost.
本发明公开了本发明提供的一种深浅基坑施工结构，包括深基坑和浅基坑，所述深基坑和浅基坑之间设置有支护桩，所述支护桩顶部固装有冠梁，所述冠梁为围绕深基坑设置的环状结构，位于所述浅基坑一侧的所述冠梁侧面设置有加腋梁，所述加腋梁纵向截面为倒置的梯形结构，所述加腋梁用于拉结所述冠梁。本发明通过在冠梁外侧加设加腋梁，有效提高了支护桩的稳定性，大幅提升了支护桩的承载能力，使其可以满足先开挖浅基坑再开挖深基坑的施工要求，极大地提高了施工效率及安全性。本发明通过第一上皮筋、第二上皮筋、和下皮筋确保底板、加腋梁、冠梁之间牢固连接，进一步加固了施工结构，有效提高了施工结构的承载能力，且该方法简单易操作，成本低。
