Recoverable combined type anchor device and construction method thereof

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.

Description

technical field [0001] The invention relates to foundation pit support engineering, in particular to a recyclable composite anchoring device and a construction method thereof. Background technique [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, which wastes a lot of materials during the construction period and increases a lot of construction costs. If these temporary facilities are supported by recyclable ...
