High-strength concrete-filled steel tube precast pile
The invention discloses a high-strength concrete-filled steel tube precast pile. The high-strength concrete-filled steel tube precast pile comprises a precast pile body, wherein steel sleeves sleeve the upper end and the lower end of the surface of the precast pile body; two sides of the lower end of the surface of the precast pile body are movably connected with fixed inserting blocks; and the ends, which are positioned in an inner cavity of the precast pile body, of the fixed inserting blocks are fixedly connected with limiting blocks. The precast pile body is driven into the ground, then a pile driver impacts a guide rod downwards, when moving downwards, the guide rod drives limiting pulleys to move, the limiting pulleys slide downwards in inner cavities of limiting chutes, thus, the limiting blocks are driven to move, the limiting blocks drive the fixed inserting blocks to move towards the outside of the precast pile body, the fixed inserting blocks can be inserted in soil, and as a result, the stability of the precast pile body is improved, the strength of the precast pile body is improved, and the problems that an existing concrete precast pile for a building is not fixed firmly and is easy to shake, potential safety hazards exist, and the engineering quality cannot be ensured are solved.
本发明公开了一种高强度钢管混凝土预制桩，包括预制桩本体，所述预制桩本体表面的上端和下端均套设有钢套，所述预制桩本体表面下端的两侧均活动连接有固定插块，所述固定插块位于预制桩本体内腔的一端固定连接有限位块。本发明通过将预制桩本体打入地下，然后通过打桩机将导杆向下冲击，导杆在向下运动时带动限位滑轮运动，限位滑轮在限位滑槽的内腔向下滑动，从而带动限位块运动，限位块带动固定插块向预制桩本体的外部运动，固定插块会插入土壤，从而增强预制桩本体的稳定性，提高预制桩本体的强度，解决了现有的建筑用混凝土预制桩由于固定不牢靠、易晃动，不仅存在安全隐患，而且工程质量也得不到保证的问题。
