Embodiment 1

[0040] like figure 1As shown, the present invention consists of the flexible anchor rod body 1 placed in the anchor hole after rotation, the grout body 5 and the anchor head fixing part 2 bonded to the anchor rod body after the grout poured into the anchor hole 3 is solidified The anchor rod body 1 is composed of rotatable and bendable steel strands, steel wire ropes, steel wire bundles or engineering plastics, and is placed in the anchor hole 3. The anchor hole 3 is divided into an anchoring section 11 and a free section 12, wherein the anchor rod body 1 The straight section is placed in the free section 12, the rotary section is placed in the anchor hole anchor section 11, and the end is placed outside the anchor hole 3, which is convenient for control during recovery. It is characterized in that: on the rotary section of the anchor rod body 1, A supporting piece 4 is provided, and the supporting piece 4 can be deformed according to the rotation shape of the anchor rod body ...

Embodiment 2

[0048] like figure 2 As shown, the anchor rod body 1, the grouting body 5 and the anchor rod head fixing part 2 in this embodiment are the same as those in the first embodiment, the difference is that the bracket 4 can cover the surface of the turning section of the anchor rod body 1 The mesh member 42, as shown in the figure, the mesh member 42 can be an elastic, bendable mesh, the mesh can be made of metal wires, or can be made of other materials, and can also be a three-dimensional with a certain thickness. It is a flexible and elastic mesh member. When the mesh is thin, it can be wrapped in multiple layers, or it can be made by repeatedly winding the mesh. It is attached to the anchor rod body by wire tie or other fastening methods. 1 rotation The outer surface of the section is deformed according to the rotation shape of the bolt body 1, and the mesh aperture on it can fully allow the grout to pass through and infiltrate. When the rotary anchor rod is placed in the anch...

Embodiment 3

[0056] like image 3 As shown, the anchor rod body 1, the grouting body 5 and the anchor rod head fixing member 2 in this embodiment are the same as those in the first and second embodiments, the difference is that the supporting member 4 is a sleeve set on the surface of the rotating section of the rod body Sleeve 43, as shown in the figure, the sleeve 43 can be a perforated elastic sleeve or the side wall of the sleeve has a mesh structure, and it is attached outside the turning section of the anchor rod body 1 through iron wire tie or other fastening methods The surface is deformed according to the rotation shape of the bolt body 1, and the upper hole diameter can fully allow the grout to pass through and infiltrate. When the rotary anchor rod is placed in the anchor hole 3, the sleeve 43 can be combined with the grout during grouting, so that the consolidated body after grouting forms a carrier with a sleeve skeleton, which improves the grouting body 5. strength, and can ...

Abstract

A rod-body revolving anchor, including a rod body that is placed in the anchor hole after rotation, the end of the rod body is placed outside the anchor hole, the straight section is set at the free section of the anchor hole, the rotary section is placed at the anchoring section of the anchor hole, the rod body The middle part is folded in half to form a rotary section, and both ends are placed outside the anchor hole. On the rod body of the rotary section, there is a bracket that can be deformed according to the rotation shape so as to facilitate the sliding of the rod body when it is pulled out. The components are combined with the grouting body poured into the anchor hole during construction to form a bearing body that bears the tension of the anchor rod. The bracket can be a deformable member placed inside the rotary section of the rod body; or an elastic member that can drive the rotary section of the rod body to expand; it can also be a mesh member or an elastic sleeve with holes or a side surface on the rotary section of the rod body. The wall is a net-shaped sleeve, and it can also be a hoop-shaped or helical member wound on the surface of the rotating section of the rod body. The invention provides a rotary anchor with simple structural design, material saving, convenient construction and installation, recyclable rod body and can be used as a pressure anchor.

Description

【Technical field】 [0001] The invention relates to the field of soil layer or rock engineering foundation and slope support, in particular to a rotatable anchor rod for support, which is mainly used in engineering fields such as geotechnical engineering, foundation pits, and slopes. 【Background technique】 [0002] The anchoring technology in the ground treatment method is to fix one end of the tensioned anchor rod in the rock layer or soil layer of the slope or foundation, and connect the other end with the structure, and use the anchoring force to withstand the force exerted by the earth pressure, water pressure or wind force. The thrust of it and the structure, so as to maintain the stability of the structure. But generally speaking, after the mission of the anchor is completed, it will be permanently buried in the concrete, which will not only waste materials, but also cause damage to the underground environment. At the same time, the long anchor may extend into the founda...
