Problems solved by technology

When the temporary support function fails, the traditional anchor rod cannot be recycled, and it is buried underground together with the built structures, occupying a large amount of underground space, forming underground garbage, causing underground environmental pollution, and causing damage to adjacent plots. Development has a great impact; at the same time, it also causes waste of steel because the anchor rod cannot be recycled

Abstract

The invention relates to a recovery type anchor bar, comprising an outer sleeve steel pipe, a screw rod disposed in the outer sleeve steel pipe along the axial direction, an upper cover board fixed on the top of the outer sleeve steel pipe, a regulation nut disposed at center of the upper cover board, a lower cover board fixing on the bottom end of the outer sleeve steel pipe, an anchor cone disposed right under the lower cover board, and a plurality of upper connection boards disposed on bottom end of the lower cover board, wherein the upper portion of the screw rod is attached to the regulation nut through a screw thread, the lower portion of the screw rod is attached to the anchor cone. Each upper connection boards is hinged to the top of an upper pulling rod, bottom end of each upper pulling rod is hinged to the top of a lower pulling rod, bottom end of each lower pulling rod is respectively attached to the anchor cone through a pin. Object of the invention is to provide a recovery type anchor bar which is high in shearing resistance capacity, underground space saving, underground environment pollution-free, and steel saving.

Description

technical field [0001] The invention relates to an anchor rod used in foundation pit support engineering. Background technique [0002] In the construction of foundation pit support in civil engineering, bolt support is a construction technology commonly used for soil wall support during excavation of foundation pits. Its advantages are: it can provide a large working surface, and there is less interference with other processes. The technology is mature, the construction is simple, the cost is low, and the application range is wide; especially suitable for the foundation pit with a large excavation surface. When the excavation area of ​​the foundation pit is large, it will cause great difficulties if the internal support is used, and the support arrangement is complicated, which seriously affects other Process construction. Therefore, various types of soil anchor technology are widely used in slopes, foundation pits, tunnels, underground pipelines and anti-floating projects...
