Problems solved by technology

[0002] In engineering construction, it is often necessary to anchor and support some temporary facilities. For example, in urban construction, some temporary excavations need to be supported by anchor cables. The existence of these anchor rods (cables) not only causes damage to the foundation underground environment In addition, it also greatly affects the later construction of surrounding buildings; at the same time, it needs to consume a lot of materials such as steel (bar) strands, cast iron anchor heads, and cement slurry.
[0003] The anchor rods (cables) in these temporary facilities are usually not recyclable, a lot of materials are wasted during the construction period, and a lot of construction costs are increased

Embodiment Construction

[0026] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0027] see Figure 1-Figure 2 ,

[0028] A recyclable composite anchoring device includes: a free section, an anchor section and a panel, the free section and the anchor section are connected through a panel, the free section is an unbonded steel strand, and the anchor section is made of an environment-friendly material.

[0029] One end of the anchoring section is a fixed end, and the fixed end passes through one side of the panel and is fixedly connected to the panel through a fixed end cover.

[0030] The fixed end cover includes a special fixed nut and a special fixed cover, the special fixed nut fixes the anchor section on the panel, and th...

Abstract

The invention discloses a recoverable combined type anchor device and a construction method of the recoverable combined type anchor device. The recoverable combined type anchor device is formed by a free section and an anchorage section which are connected through a surface plate. One end of the anchorage section is a fixed end which penetrates through one side of the surface plate, a hydraulic jack is fixedly arranged on the surface plate, and the hydraulic jack contacts with the fixed end. The construction method of the recoverable combined type anchor device comprises firstly arranging the assembled anchor device in an anchor hole, carrying out slip casting to the anchorage section, carrying out tensioning processing to the free section, breaking composite materials through the micro hydraulic jack in a jacking mode and enabling the composite materials to be separated from a surface plate device when the using of the anchor device is completed, and therefore pulling the free section out of the anchor hole. Through the mentioned mode, the recoverable combined type anchor device and the construction method of the recoverable combined type anchor device have the function of solid connection by utilizing the ingenious combination of the surface plate and the micro hydraulic jack, can achieve the detachability and the reutilization of the free section, and are strong in economical practicality.
