The invention discloses a grouting extrusion-expansion prestressed pipe pile, and relates to the field of buildings. The grouting extrusion-expansion prestressed pipe pile comprises a prestressed pipepile body, a pile head and a grout restraining device, wherein the prestressed pipe pile body is connected with the pile head; the outer diameter of the pile head is matched with that of the prestressed pipe pile body; the pile head comprises a pile tip, a steel pipe, an upper sealing plate, a lower sealing plate and a limiting device; the pile tip is arranged on one side of the upper sealing plate; one end of the steel pipe is connected with the other side of the upper sealing plate in a sealed mode; the lower sealing plate comprises a grouting opening and is arranged at the other end of thesteel pipe in a sealed mode; a grouting overflow opening is formed in the wall face of the side of the steel pipe; and the limiting device is arranged on the peripheral wall face of the steel pipe; and the grout restraining device is connected to the outer side of the pile head through the limiting device and the peripheral wall face and covers the grouting overflow opening. The grouting extrusion-expansion prestressed pipe pile has the technical effects of being easy and convenient to construct, low in comprehensive cost and small in influence on the environment.
本发明公开了一种注浆挤扩预应力管桩，涉及建筑领域，包括预应力管桩、桩头和束浆装置，所述预应力管桩与所述桩头连接，所述桩头的外径与所述预应力管桩匹配，其中，所述桩头包括桩尖、钢管、上封板、下封板、限位装置，所述桩尖设置于所述上封板的一侧；所述钢管的一端与所述上封板的另一侧封闭连接，所述下封板包括注浆口，所述下封板封闭设置于所述钢管的另一端，所述钢管侧方的壁面上设有注浆溢口，所述限位装置设置于所述钢管外周壁面，所述束浆装置通过所述限位装置与所述外周壁面连接于所述桩头外侧，所述束浆装置覆盖所述注浆溢口。本发明的技术效果在于施工简便、综合成本低廉、对环境影响小。
