Anchor rod water stop member, anchor rod and water stop method

Abstract

The invention provides an anchor rod water stop member. The anchor rod water stop member comprises a water stop plate used for being buried in a concrete member, a connecting hole is formed in the center of the water stop plate, and internal threads matched with external threads on the outer wall of an anchor rod body are arranged on the inner wall of the connecting hole, so that the water stop plate is screwed and sleeves the external threads of the anchor rod body and is pressed on flexible water stop interlayers arranged on the external threads of the anchor rod body. The invention further provides an anchor rod with the water stop member and a water stop method. Flexible connection can be formed between the water stop plate and the anchor rod body, the influence of stress strain and deformation of the anchor rod body on the concrete member is reduced, and the possibility that a gap is generated between the outer surface of the anchor rod body and the concrete member or even the anchor rod body is disengaged from the concrete member to cause leakage is avoided; and no matter the anchor rod body is pulled or pressed, the flexible water stop interlayers can be always pressed and sealed by the water stop plate, it is guaranteed that the anchor rod body and the water stop plate are sealed and waterproof, the path that underground water leaks into the concrete member along the outer wall of the anchor rod body is completely blocked, and the use reliability of the anchor rod is improved.

Description

technical field [0001] The invention relates to the technical field of anchor rods, in particular to an anchor rod water-stop component, an anchor rod and a water-stop method. Background technique [0002] Anchor is a commonly used structure in geotechnical engineering. It is a tension member and its system anchored in the formation. It is used to transfer the load of the external structure to the formation to keep the external structure stable. It is widely used in Urban infrastructure construction and water conservancy, hydropower, transportation, railway, mine and other projects are under construction. [0003] Most of the underground structures of construction projects will be equipped with anti-floating anchor rods, mainly to resist the upward displacement of the buildings above them. The anti-floating anchor rod is connected with the basement floor, and the basement floor is generally provided with a waterproof layer to prevent groundwater from seeping through the bas...

AI Technical Summary

Problems solved by technology

Most of the existing technologies are to set a water-stop ring on the rod body. According to the concrete material when the concrete member is poured, the water-stop ring is pressed tightly to achieve the purpose of water-stop, but its reliability is poor, and it will become invalid with the repeated deformation of the rod body, and the groundwater is still easy. Leakage into the concrete member along the outer wall of the anchor rod body
