Multi-pile connecting rod combined foundation for high-rise structure and using method of multi-pile connecting rod combined foundation
The invention provides a multi-pile connecting rod combined foundation for a high-rise structure and a using method. The multi-pile connecting rod combined foundation comprises pile bodies and wing plate devices. A grouting sleeve sleeves and is fixed on the outer wall of the pile body, a first supporting block for supporting the wing plate device is arranged on the inner wall of the pile body, at least one wing plate preformed hole is formed in the part, corresponding to the grouting sleeve, of the pile body, and the wing plate preformed hole penetrates through the grouting sleeve; the wing plate device comprises a wing plate matched with the wing plate preformed hole and a wing plate mounting platform connected to the first supporting block; the wing plate can move along a rail groove in the wing plate mounting platform, and the rail groove is communicated with one wing plate preformed hole; and a pushing component is fixed in the rail groove. The pre-tensioning horizontal load generated by the upper connecting rod is counteracted through the wing plates, the lateral displacement of a single pile is reduced, and therefore the stability of the foundation is improved; single piles are connected through the connecting rods and the sleeve connecting devices to form the combined foundation, the top load form of the single piles is optimized, and therefore the stability of the foundation is improved.
本发明提出了一种用于高耸结构物的多桩连杆组合基础及使用方法，该基础包括桩身和翼板装置；桩身的外壁上套设并固定一注浆套筒，桩身的内壁上设置用于支撑翼板装置的第一支撑块，桩身对应注浆套筒的部分开设至少一翼板预留孔，翼板预留孔贯穿注浆套筒；翼板装置包括与翼板预留孔适配的翼板、承接于第一支撑块上的翼板安装平台；翼板可沿翼板安装平台上的轨道凹槽移动，轨道凹槽连通其中一翼板预留孔；轨道凹槽内固定一推动构件。本发明通过翼板来抵消上部连杆产生的预张水平荷载，减少单桩侧向位移，从而提高基础的稳定性；通过连杆、接套筒装置来将单桩相互连接形成组合基础，优化单桩顶部荷载形式，从而提高基础的稳定性。
