Hollow UHPC (Ultra High Performance Concrete) square pile with stiffening ribs and connecting method thereof
The invention discloses a hollow UHPC square pile with stiffening ribs and a connecting method thereof.The hollow UHPC square pile with the stiffening ribs is characterized in that the hollow UHPC square pile with the stiffening ribs is fixedly connected with the UHPC square pile through a sleeve, a unilateral bolt and a high-strength grouting material in a matched mode, each UHPC square pile comprises two UHPCs, an inner thin-wall round steel pipe, the stiffening ribs, longitudinal bars, welding seams, stirrups and end plates, holes are formed in a stiffening rib steel plate, and the inner thin-wall round steel pipe and the longitudinal bars are connected through the welding seams. The end plate is located at the UHPC end, and the longitudinal bar penetrates through the end plate and is in plug welding with the end plate. The connecting method comprises a sleeve, a unilateral bolt and a high-strength grouting material, the sleeve is connected with the end plate through the unilateral bolt, the high-strength grouting material is poured between the inner steel pipe and the unilateral bolt, and the high-strength grouting material plays a role in anchoring the longitudinal bar. The method has the advantages of being reliable in connection, high in construction efficiency, economical, environmentally friendly, visual in construction process, transparent in grouting quality and capable of effectively improving the construction efficiency and guaranteeing the construction quality. And the bearing capacity of the hollow UHPC square pile can be obviously improved.
本发明公开了一种带加劲肋中空UHPC方桩及其连接方法，包括带加劲肋中空的UHPC方桩，以及UHPC方桩之间配合套筒、单边螺栓、高强灌浆料进行固定连接，所述UHPC方桩包括两个UHPC、内薄壁圆钢管、加劲肋、纵筋、焊缝、箍筋和端板，所述加劲肋钢板上开有孔洞，所述端板位于UHPC端部，所述纵筋穿过所述端板与端板塞焊。连接方法包括套筒、单边螺栓、高强灌浆料，所述套筒与所述端板通过所述单边螺栓连接，所述高强灌浆料灌注于内钢管与单边螺栓之间，所述高强灌浆料对所述纵筋起到锚固的作用。本发明具有连接可靠，施工效率高，经济环保，施工过程可视化，灌浆质量透明化，可有效提高施工效率并保证施工质量。可显著提高中空UHPC方桩的承载力。
