The invention belongs to the technical field of geotechnical engineering, and particularly relates to a prestressed anti-corrosion durable device. The prestressed anti-corrosion durable device comprises a prestressed steel strand, an outer sleeve, a grouting pipe, a positioning bracket, a fixing device, a grouting body and a guiding device, wherein the outer sleeve wraps the prestressed steel strand; the grouting pipe is located in the middle of the prestressed steel strand; the fixing device is provided with a first fixing piece and a second fixing piece, the first fixing piece is used for tensioning and locking the upper end of the prestressed steel strand, the second fixing piece is used for tensioning and locking the lower end of the prestressed steel strand, and the second fixing piece is provided with a bearing body for improving the bearing strength; the grouting body is used for grouting into an anchor rod drill hole through the grouting pipe, and the inner side and the outer side of the prestressed steel strand are poured into an integrated cylindrical column body; and the guiding device is used for protecting the second fixing piece and guiding when the second fixing piece is embedded into the anchor rod drill hole. According to the prestressed anti-corrosion durable device, the guiding device can facilitate the prestressed steel strand and the grouting pipe to be quickly inserted into the ground, and the second fixing piece can be protected so as to be prevented from being corroded.
本发明属于岩土工程技术领域，尤其涉及一种预应力防腐耐久装置，包括：预应力钢绞线；外套管，包裹预应力钢绞线设置；注浆管，位于预应力钢绞线中部；定位支架；固定装置，具有第一固定件和第二固定件，其中，第一固定件对预应力钢绞线的上端进行张拉锁定，第二固定件对预应力钢绞线的下端进行张拉锁定，第二固定件具有提高承载强度的承载体；注浆体，通过注浆管向锚杆钻孔内注浆，将预应力钢绞线的内侧以及外侧浇注成一体的柱形柱体；导向装置，用于对第二固定件进行防护以及在嵌入锚杆钻孔内时进行导向。本发明的导向装置能够方便预应力钢绞线及注浆管快速插入到地下，而且还能够对第二固定件进行防护，以避免第二固定件被腐蚀。
