Non-middle beam supporting structure for pile-anchor supporting structure rapid construction and construction method thereof

Abstract

The invention provides a non-middle beam supporting structure for pile-anchor supporting structure rapid construction and a construction method thereof. According to the non-middle beam supporting structure for pile-anchor supporting structure rapid construction, through an anchor cable, a cross-shaped anchorage device and a structure connected with supporting piles, the complex construction problem that steel strands are locked on the supporting piles by adopting counter-pulling bearing structures in an existing pile-anchor supporting method of a non-middle beam framework is solved; and a middle beam with complex construction in an existing pile-anchor supporting structure is avoided, so that the non-middle beam supporting is achieved, and the construction period is greatly shortened. Theconstruction method comprises the following steps of firstly, pressing a cross-shaped anchorage device cable pressing plate against the split anchor cable steel strands, then penetrating into the locking the anchor cable steel strands, and tensioning the locking anchor cable steel strands by a locking plate to a designed prestress value. The anchorage device greatly simplifies the non-middle beamconstruction of the pile-anchor supporting structure.

Description

technical field [0001] The invention relates to a non-waist beam supporting structure and a construction method thereof for rapid construction of a pile-anchor supporting structure, and belongs to the technical field of building construction. Background technique [0002] Pile-anchor support technology is widely used in foundation pit support, slope support and other projects. Its main components are support piles, waist beams and anchor cables. The way of force transmission is that the soil pushes the support piles to deform, and the support piles are pressed against the waist beams, driving the waist beams to pull the anchor cables, and the anchor cables rely on the bonding between the grouting body and the rock-soil body to provide pull-out resistance and maintain The safety and stability of the entire support system. [0003] The waist beam of pile anchor support is the main transmission component, and the commonly used waist beams are reinforced concrete waist beams a...
