Spherical rotating anchorage device and retaining wall anchoring structure

Abstract

The invention provides a spherical rotary anchorage device and a retaining wall anchoring structure, the spherical rotary anchorage device comprises an anchor rod, an anchor cup and a spherical bearing body matched with the anchor cup, the spherical bearing body is rotatably matched in a spherical groove of the anchor cup, and the spherical surface of the spherical bearing body is matched with the spherical surface of the spherical groove. The anchor rod penetrates through the spherical bearing body and is anchored on the spherical bearing body through the locking piece; an anchor cup of the retaining wall anchoring structure is fixed in a concrete structure, a horn mouth of the anchor cup is arranged towards the inner side of the concrete structure, a spherical groove of the anchor cup is arranged towards the outer side of the concrete structure, and a plane of a spherical bearing body is arranged towards the outer side of the concrete structure. Various vertical and transverse angle requirements between the anchor rod and a concrete structure can be met, various types of standard anchorage device products are formed, factory batch production is facilitated, the situation of manual operation of a traditional anchor pier is fundamentally ended, and the production efficiency is improved. The method has the advantages of reliable quality, low cost, short construction period, easiness in implementation, simple construction process, suitability for fabricated structures and the like.

Description

technical field [0001] The invention belongs to the technical field of pile-anchor retaining walls and assembled bolt retaining walls, and particularly relates to a spherical rotating anchor and a retaining wall anchoring structure using the anchor. Background technique [0002] Anchorage is the most commonly used support method in slope engineering. In pile-anchor retaining walls and prefabricated bolt retaining walls, it involves the construction of the concrete structure first, and the construction of the bolt and anchor cable. In this case, the connection of the anchor cable / bolt to the concrete structure is a problem that needs to be solved. The traditional scheme mainly adopts the addition of external anchors on the already constructed concrete structure, and then performs effective anchoring on the external anchors. The disadvantage of this method is: due to the constant change of the slope, the angle of the anchor rod and the anchor cable, it is impossible to form a...

AI Technical Summary

Problems solved by technology

The disadvantage of this method is: because the angle of the slope and the anchor rod and the anchor cable has been changing, it is impossible to form a fixed standard external anchor pattern; the connection between the external anchor and the concrete structure that has been constructed requires planting reinforcement or repairing the existing structure. The chiseling will cause certain damage to the existing structure and increase the cost; it will take time for the external anchorage concrete to consolidate, which has a great impact on the construction period, and there is a safety hazard of temporary stability during the construction period

Another method is to use steel members as the outer anchorage. Although this method can reduce the concrete consolidation time of the outer anchorage and shorten the construction period, the above-mentioned other defects still exist
