YUAN JIAKANG / YUAN JIAJIN / YUAN JIAWEI / YUAN LIANJIA

The invention relates to the technical field of soft soil texture deep foundation pit supporting, and discloses a soft soil texture deep foundation pit supporting excavation construction structure and a construction method.The soft soil texture deep foundation pit supporting excavation construction structure comprises a transverse supporting plate arranged at the bottom of a deep foundation pit and a vertical supporting plate arranged on the side wall of the deep foundation pit; the top of the transverse supporting plate is provided with an abutting part used for abutting against the vertical supporting plate. The abutting part comprises an abutting panel sliding above the transverse supporting plate, a plurality of abutting straight rods perpendicularly fixed to the side wall, close to the vertical supporting plate, of the abutting panel, and abutting balls arranged at the ends, close to the vertical supporting plate, of the abutting straight rods. The top of the transverse supporting plate is provided with a driving part used for driving the abutting panel to be close to the vertical supporting plate. The supporting device has the effect that the situation that the supporting device needs to be remanufactured due to the fact that the inclination angle of the side wall of the foundation pit cannot adapt to the device is improved.

本发明涉及软土地质深基坑支护的技术领域，公开的一种软土地质深基坑支护开挖施工结构及施工方法，包括设于深基坑底部的横向支护板以及设于深基坑侧壁的竖向支护板，所述横向支护板顶部设有用于抵压所述竖向支护板的抵压部件，所述抵压部件包括滑移于所述横向支护板上方的抵压面板、若干个垂直固定于所述抵压面板靠近所述竖向支护板的侧壁的抵压直杆、设于所述抵压直杆靠近所述竖向支护板的端部的抵压圆球；所述横向支护板顶部设有用于驱动所述抵压面板靠近所述竖向支护板的驱动部件。本申请具有改善基坑侧壁倾斜角度不能与该装置相适应而需要重新制造支护装置的效果。
