The invention provides a prefabricated anchoring foundation for a frozen soil foundation of a transformer substation, and belongs to the technical field of transformer substation foundations. The prefabricated anchoring foundation for the frozen soil foundation of the transformer substation comprises a cylinder body, a plurality of expansion plates, a plurality of expansion nails and a column body, wherein the bottom end of the cylinder body penetrates through a frozen soil layer and extends to the position below the frozen soil layer, the bottom end is a closed end, and the top end is an open end; the multiple expansion plates are vertically and symmetrically arranged in the part, located below the frozen soil layer, of the cylinder body, and each expansion plate is tightly attached to the inner wall of the cylinder body; the multiple expansion nails are vertically arranged on the outer side wall of each expansion plate at equal intervals, the ends, away from the expansion plates, of the expansion nails penetrate through the cylinder body and extend outwards to form anchoring ends, and through holes allowing the expansion nails to penetrate through are formed in the cylinder body; the column body is inserted into the cylinder body and located between the oppositely-arranged expansion plates, and the top of the column body is used for a pile foundation for building the transformer substation. According to the prefabricated anchoring foundation for the frozen soil foundation of the transformer substation, the expansion plates are pressed and tightly attached to the inner side wall of the cylinder body, the expansion nails arranged on the expansion plates penetrate through the cylinder body to be pressed into soil bodies on the two sides of the cylinder body in the pressing process, the anchoring effect is achieved, and the stability of the cylinder body can be effectively enhanced.
本发明提供了一种用于变电站冻土地基的预制锚固基础，本发明属于变电站基础技术领域。包括：筒体，底端穿过冻土层，延伸至冻土层以下，且底端为封闭端，顶端为敞口；多个胀板，其均竖向对称设置于位于冻土层以下部分的筒体内，每个胀板均紧贴于筒体内壁；多个胀钉，竖向等间隔均垂直设置于每个胀板的外侧壁上，且远离胀板的一端穿过筒体向外延伸形成锚固端，筒体上开设有供每个胀钉穿过的通孔；柱体，其插设于筒体内，且位于相对设置的胀板之间，柱体顶部用于供变电站搭建的桩基础。本发明通过将胀板压制紧贴于筒体内侧壁，在压制的过程中，胀板上设置的胀钉将穿过筒体压向筒体两侧的土体内，起到锚固作用，能够有效增强筒体的稳定性。
