Micro pile foundation pit supporting device and method
The invention provides a micro pile foundation pit supporting device and method, and belongs to the technical field of foundation pit supporting, the micro pile foundation pit supporting device comprises multiple pile bodies, a base plate, an anti-torque mechanism and an outer supporting mechanism, the multiple pile bodies are evenly distributed, mounting cavities are formed in the pile bodies, and limiting grooves are formed in the tops of the pile bodies; the multiple base plates correspond to the pile bodies in position, and inclined rods are arranged between the base plates and the corresponding pile bodies. The multiple sets of anti-torsion mechanisms are arranged on the limiting grooves correspondingly, each anti-torsion mechanism comprises a lower supporting ring, an upper supporting ring and a spring, the lower supporting rings and the upper supporting rings are slidably connected to the surfaces of the limiting grooves, and the springs are located between the lower supporting rings and the upper supporting rings; the multiple sets of outer supporting mechanisms are arranged on the pile bodies correspondingly, and the supporting effect is improved by enlarging the supporting area of the outer supporting mechanisms. The stress is diffused outwards along with the linkage effect of the crossed folding rods so as to reduce deformation caused by pressure, and the supporting strength and the supporting effect can be effectively improved through the elastic effect of the springs.
本发明提供一种微型桩基坑支护装置及方法，属于基坑支护技术领域，包括桩体、基板、抗扭机构和外撑机构，桩体设置有多个并均匀分布，其内部均设置有安装腔，其顶部均设置有限位槽；基板设置有多个并与桩体的位置相对应，其与对应桩体之间均设置有斜杆；抗扭机构设置有多组并分别设置于每个限位槽上，其均包括下支撑圈、上支撑圈和弹簧，下支撑圈和上支撑圈均滑动连接于限位槽的表面，弹簧位于下支撑圈和上支撑圈之间；外撑机构设置有多组并分别设置于每个桩体上，其通过扩大支撑面积以提高支护作用；随着交叉折叠杆的联动作用，将受力向外扩散，以减少压力导致的形变，并通过弹簧的弹性作用，可有效提高支撑强度，加强支护作用。
