Connection structure of concrete precast pile
The invention discloses a connection structure of a concrete precast pile, which comprises a pile end plate pre-embedded on the end face of the precast pile and a pile hoop pre-embedded at the end of the precast pile in a sleeving manner, two anti-pulling convex ribs clamped into the pile body of the precast pile are formed on the pile hoop, and the top surface of the pile hoop and the end face of the precast pile are positioned on the same horizontal plane; the pile end plate is welded and connected with the pile hoop into a whole before the precast pile is precast, and an assembly welding seam is formed between the bottom surface of the pile end plate and the inner wall of the top end of the pile hoop; a circle of connecting clamping groove is machined in the position, close to the bottom face of the pile end plate, of the circumferential face of the pile end plate. A connecting clamp used for connecting the pile end plates of the upper precast pile and the lower precast pile into a whole in a clamped mode is installed in the connecting clamping groove in a clamped mode, and the connecting clamp is formed by combining at least two unit connecting clamps. The method is high in connection speed, safe and reliable, the tensile strength and small strain detection after the two piles are in butt joint can be guaranteed, and the problems that the traditional pile foundation connection quality cannot be guaranteed, the drawing resistance bearing capacity is insufficient, and small strain detection is difficult are solved.
本发明公开了一种混凝土预制桩的驳接结构，包括预埋在预制桩桩端面上的桩端板和套装预埋在预制桩桩端的桩套箍，桩套箍上成型有两道卡入到预制桩桩身内的抗拔凸筋，桩套箍的顶面与预制桩的桩端面处于同一水平面上；桩端板在预制桩预制前与桩套箍焊接相连成一体，桩端板的底面与桩套箍顶端的内壁间形成有组装焊缝；桩端板的周面上在紧邻桩端板的底面处加工有一圈连接卡槽；连接卡槽中卡装有用于将上下两节预制桩的桩端板卡接相连成一体的连接卡箍，连接卡箍至少由两个单元连接卡箍组合构成。本发明连接速度快，并且安全可靠，能保证两桩对接后的抗拉强度及小应变检测，解决了传统桩基连接质量不能保证、抗拉拔力承载力不足、小应变检测难等问题。
