Positioner for profile steel fender pile construction and profile steel construction method

Abstract

The invention discloses a positioner for profile steel fender pile construction and a profile steel construction method, wherein profile steel can be inserted into a cement cob wall according to designed axis when the profile steel is inserted into the stirred cement cob wall by means of a TRD construction method or an SMW construction method, so that the profile steel in the cement cob wall is ina vertical state and the steel profile can be inserted into the stirred cement cob wall according to the separation distances required by the design. The positioner for profile steel fender pile construction comprises a supporting and positioning framework and at least two movable positioning frames, wherein two slot cross beams which are parallel to each other are arranged on the supporting andpositioning framework, and a plurality of positioning slots are formed in the slot cross beams; each movable positioning frame comprises a positioning top frame, a positioning bottom frame below the positioning top frame and a vertical connecting rod which connects the positioning top frame and the positioning bottom frame. The movable positioning frames are hung on the two slot cross beams through the positioning top frames, and the positioning top frames are positioned in the positioning slots of the slot cross beams.

Description

technical field [0001] The invention relates to the construction field of a cement-soil continuous wall, in particular to a positioner for the construction of a section steel enclosure pile and a section steel construction method. Background technique [0002] For basement pits of buildings or structures, construction pit curtains (ie, water-stop curtains) are often required to seal off groundwater from the outside of the foundation pit, and at the same time provide active earth pressure outside the retaining pit. The current foundation pit curtain is usually constructed using the TRD construction method and the SMW construction method. First, the underground cement-soil wall is constructed, and then section steel (usually H-section steel) is sequentially inserted into the cement-soil wall according to the design spacing requirements of the section steel to form the foundation pit enclosure wall. [0003] During the construction of TRD and SMW construction methods, whether t...

Problems solved by technology

Therefore, how to ensure that the shaped steel can be inserted into the cement-soil wall accurately along the design axis during construction, so that the shaped steel inserted into the cement-soil wall is in a vertical state is very important; especially, when the upper end of the shaped steel is buried in the cement-soil wall At this time, because the cement-soil wall covers the upper end of the section steel, when the specific position of the section steel cannot be judged by the naked eye, the insertion of the section steel is a major difficulty
