Support pile shotcreting and anchoring structure and construction method
The invention discloses a support pile shotcrete-anchor structure and a construction method, pre-embedded hanging net connecting steel bars are arranged on a steel reinforcement cage in a cast-in-place pile, a connecting steel bar net sheet is straightened during net hanging and then is flatly broken off to be welded with the steel bar net sheet after net hanging, two pre-embedded hanging nets are arranged in the cast-in-place pile in a V shape and are firmly clamped on the cast-in-place pile in a two-way vertical mode, and the cast-in-place pile is fixedly connected with the cast-in-place pile. The expansion bolts are driven into the cast-in-place piles, the short steel bars welded to the expansion bolts are also welded to the steel bar meshes, double connection and matching are achieved, the forming quality of the supporting structure is guaranteed, construction is convenient and easy, and the supporting structure is easy to use; the problem of poor stability caused by poor rebar planting effect due to difference of construction levels of workers is avoided, the construction quality and the construction period of the supporting structure are effectively improved, and the engineering cost is saved.
本发明公开了一种支护桩喷锚结构及施工方法，灌注桩内的钢筋笼上设置预埋挂网连接钢筋，连接钢筋网片挂网时先掰直，挂网后再掰平与钢筋网片焊接，两根预埋挂网呈V型布置在灌注桩内，双向垂直的牢固扒紧在灌注桩上，保证了钢筋网片与灌注桩的结合，从而喷射混凝土面层成型后结构牢固，并且配合膨胀螺栓打入灌注桩，膨胀螺栓上焊接的短钢筋与钢筋网片也焊接，双重连接配合，保证了支护结构的成型质量，施工方便简单，容易上手，避免了工人施工水平存在差异而植筋效果差导致的稳定性欠佳的问题，有效提升支护结构施工质量及施工周期，节约工程成本。
