Expansion pipe type friction pile and construction method thereof
The invention discloses an expansion pipe type friction pile and a construction method thereof, and relates to the technical field of friction piles, the expansion pipe type friction pile comprises a reinforcing steel pipe, a top plate is welded to the top of the reinforcing steel pipe, and a plurality of pieces of thorn steel are welded to the inner bottom surface of the reinforcing steel pipe; and the sinking assembly comprises a bearing bottom ring. When the device is used, water is injected into the sinking assembly, the sinking assembly is pressed downwards through water pressure, in the downward pressing process, the sharp thorn steel at the top can pierce the foam blocking plate, meanwhile, the foam blocking plate is jacked upwards, the foam blocking plate moves upwards to be separated from the mounting groove, and granular water absorption substances fall down from gaps; when the water absorption material is conveyed downwards, the water absorption material sinks downwards under the action of gravity and enters the multiple expansion steel pipes, at the moment, the water absorption material expands when meeting water, the sinking assembly continues to sink under the impact of the water, the thorn steel pierces the foam waterproof plate, and the water flows downwards from the space between the protective surrounding plate and the reinforcing steel pipe.
本发明公开了一种膨胀管式摩擦桩及其施工方法，涉及摩擦桩技术领域，包括：加强钢管，所述加强钢管的顶部焊接有顶板，所述加强钢管的内部底面焊接有多个刺钢；下沉组件，所述下沉组件包括有承托底环。本发明在使用时，通过向下沉组件处注水，水压将下沉组件向下压，在下压的过程中，顶部尖锐的刺钢会将泡沫堵板刺穿，同时将泡沫堵板向上顶，使得泡沫堵板向上移动与安装槽分离，颗粒状的吸水物质便从空隙中落下，向下输送的吸水物质在重力作用下向下沉，进入到多个膨胀钢管内，此时，吸水物质遇水膨胀，而下沉组件在水的冲击下继续下沉，刺钢将泡沫防水板刺破，水从防护围板与加强钢管之间的空间向下流。
