Self-hole-forming bearing head of earth anchor rod

Abstract

The invention discloses a self-hole-forming bearing head of an earth anchor rod. The self-hole-forming bearing head comprises an anchor rod body, wherein the left side of the anchor rod body is fixedly connected with a bearing head body; a slurry outlet is formed in the surface of the bearing head body; the surface of the anchor rod body is in sliding connection with a connecting pipe; the right side of the surface of the anchor rod body is in threaded connection with a baffle plate; the left side of the baffle plate is fixedly connected with a slurry stopping plug; the right side of the anchor rod body is in threaded connection with a fastening nut; a drilling rod is arranged in an inner cavity of the anchor rod body; the left side of the drilling rod is fixedly connected with a drillingbit; and the top and the bottom of the bearing head body are fixedly connected with steel sheets. According to the self-hole-forming bearing head disclosed by the invention, the anchor rod body, the bearing head body, the slurry outlet, the connecting pipe, the baffle plate, the slurry stopping plug, the fastening nut, the drilling rod and the drilling bit are matched to use, so that the problem that a traditional bearing head is easy to block in a utilization process can be effectively solved; and the device can be used for preventing the inner part of the rod from being blocked, so that thegrouting effect is improved and the construction is convenient.

Description

technical field [0001] The invention relates to the technical field of bearing heads, in particular to a bearing head with self-forming holes for soil anchors. Background technique [0002] The soil anchor is to drill a hole in the unexcavated soil layer of the deep foundation soil wall. After reaching a certain depth, put steel bars, steel pipes, steel wire bundles, steel strands and other materials into the holes, and pour mud or chemical slurry to make them It is combined with the soil layer to form an anchor rod with strong tensile (pull-out) strength, and the end of the soil anchor rod is connected with the retaining pile to prevent the soil wall from collapsing or landslide; and because there is no support in the pit, the construction conditions are better, and the traditional bearing If the head enters the inside of the hole, the dirt filled inside cannot be effectively removed, which will cause blockage and affect the grouting efficiency.
