Hinge type large-tonnage anchor device

Abstract

The invention relates to a hinge type large-tonnage anchor device, comprising a hinge type large-tonnage anchor device A and a hinge type large-tonnage anchor device B which are both provided with limiting rings at the outer side faces; limiting holes are arranged on the limiting rings; the hinge type large-tonnage anchor device A and the hinge type large-tonnage anchor device B are connected through accessory bolts so as to enable the two anchor devices to rotate relatively; lock catches are arranged on the inner side surfaces of the hinge type large-tonnage anchor device A and the hinge type large-tonnage anchor device B; lock holes are arranged on the lock catches; when the lock catches arranged on the inner side surfaces of the hinge type large-tonnage anchor device A and the hinge type large-tonnage anchor device B are matched with each other, the lock holes at least partially overlap and a bolt is inserted into the overlapped hole; a wire rope is connected at the tail part of the bolt; and when the hinge type large-tonnage anchor device A and the hinge type large-tonnage anchor device B need to be separated with each other, an operator can pull the wire rope and then pull out the bolt.

Description

technical field [0001] The invention relates to an anchoring device, in particular to a hinge-type large-tonnage anchoring device which is applied to foundation pits and slope support of geotechnical engineering, which can facilitate the insertion of anchor rods into rock-soil bodies and provide reliable anchoring force, and belongs to foundation construction field of engineering technology. Background technique [0002] With the advancement of urbanization, the construction of underground facilities such as underground parking lots, underground pedestrian passages, underground shopping malls, and underground railways requires foundation pit support. Although the use of internal support can well solve some problems in the construction of underground structures, its high cost, long construction period, and inconvenient construction of underground structures are difficult to meet the higher requirements of urban construction.

Problems solved by technology

Although the use of internal support can well solve some problems in the construction of underground structures, it is difficult to meet the higher requirements of urban construction due to its high cost, long construction period, and inconvenient construction of underground structures.

[0003] In the prior art, bolts are widely used in geotechnical engineering and have achieved very good results. However, the bolts usually used are disposable, and the bolt body remains in the soil layer after use, which not only wastes materials, and also form obstacles to the construction of adjacent buildings, causing it to increase the cost of dealing with underground obstacles in later development
