Large-diameter cast-in-place thin-wall prestressed concrete steel pipe pile
The invention relates to the technical field of prestressed concrete piles, in particular to a large-diameter cast-in-place thin-wall prestressed concrete steel pipe pile which comprises an inner steel sleeve, an outer steel sleeve and a concrete cylinder. A plurality of first transverse steel plates which are longitudinally arranged at intervals are fixedly arranged on the outer wall of the first longitudinal steel plate, a second longitudinal steel plate is detachably connected to the inner wall of the outer steel sleeve, a plurality of second transverse steel plates which are longitudinally arranged at intervals are fixedly arranged on the outer wall of the second longitudinal steel plate, and the first transverse steel plates and the second transverse steel plates are longitudinally arranged in a staggered mode; the first transverse steel plate and the second transverse steel plate are fixedly connected with deformed steel bars. A frame structure is formed by the first longitudinal steel plate, the first transverse steel plate, the second longitudinal steel plate, the second transverse steel plate and the deformed steel bars, the bearing capacity is high, the rigidity is large, manufacturing is easy, assembling is convenient, and the bending bearing capacity of concrete is effectively improved.
本发明涉及预应力混凝土桩技术领域，具体为一种大直径现浇薄壁预应力混凝土钢管桩，包括内钢套管，外钢套管，以及混凝土筒体，内钢套管的外壁可拆卸连接有第一纵向钢板，第一纵向钢板的外壁固定设有若干个呈纵向间隔设置的第一横向钢板，外钢套管的内壁可拆卸连接有第二纵向钢板，第二纵向钢板的外壁固定设有若干个呈纵向间隔设置第二横向钢板，第一横向钢板和第二横向钢板在纵向上交错设置，第一横向钢板和第二横向钢板固定连接有螺纹钢。本发明通过第一纵向钢板、第一横向钢板、第二纵向钢板、第二横向钢板和螺纹钢组成框架结构，承载能力强，刚度大，制作简单，组装方便，有效提高了混凝土的抗弯承载力。
