Abstract

The invention discloses an underground space expansion anchor rod pile positioner. The underground space expansion anchor rod pile positioner comprises a steel plate, a positioning hole, a positioning bolt and positioning nuts; the steel plate, the positioning hole, the positioning bolt and the positioning nuts interact to precisely position an anchor rod pile sleeve; the steel plate is fixed on an operation platform in an orifice position of an anchor rod pile hole; the steel plate is opened to form the positioning hole; multiple positioning nuts are uniformly distributed at the outer periphery of the positioning hole in the steel plate in the annular direction; and the positioning nuts are connected with the steel plate through welding. The underground space expansion anchor rod pile positioner adopts the positioning bolt to precisely position the anchor rod pile sleeve, and is suitable for construction of underground space expansion anchor rod piles.

Description

technical field [0001] The present invention relates to the relevant technical field of underground engineering construction, in particular to an anchor pile locator for underground space expansion Background technique [0002] With the advancement of my country's urbanization process, the construction of urban underground space is gradually developing into blocks and networks. In the process of network extension construction of underground engineering, construction problems of anchor piles are often encountered. Due to the complex surrounding environment of the urban underground space expansion project, if the positioning of the anchor piles is not accurate, it will lead to damage to the surrounding existing structures and important pipelines during the construction process. [0003] CN 212294647 U discloses a new type of composite anchor pile device with positioning and guiding sleeve method. By embedding a positioning guide pipe within the range of the vertical shaft cro...
