Construction method of vertical shaft locking notch structure and vertical shaft locking notch structure
The invention discloses a construction method of a vertical shaft locking notch structure and the vertical shaft locking notch structure. The construction method comprises the steps that a locking notch foundation trench is excavated according to a preset excavation contour line, and a preset first ring position and a preset third ring position which are concentric with the locking notch foundation trench and sequentially arranged in a sleeving mode from inside to outside are defined in the locking notch foundation trench; locking notch ring beam steel bars are bound between the preset first ring position and the preset third ring position, vertical stirrups are pre-inserted between the preset first ring position and the preset third ring position, a steel bar support is formed, and the bottom of the peripheral face of the steel bar support protrudes outwards in the radial direction to form reinforcing protrusions; embedded parts are arranged on the steel bar support; a locking notch ring beam formwork is erected on the outer side of the steel bar support in the locking notch foundation trench, and the formwork presses at least part of the reinforcing protrusions downwards; lockingnotch ring beam concrete is poured between the preset first ring position and the preset third ring position; and the locking notch ring beam formwork is dismounted and filled with graded sand inclusion stone. The reinforcing protrusions are arranged on the steel bar support, the filled graded sand inclusion stone can press the reinforcing protrusions, and the stability of the locking notch structure can be improved.
本发明公开了一种竖井锁口结构施工方法及竖井锁口结构。施工方法包括：按照预设开挖轮廓线开挖锁口基槽，锁口基槽中圈定有与锁口基槽同圆心的由内至外依次套设的预设第一圈环位置和预设第三圈环位置；在预设第一圈环位置和预设第三圈环位置之间绑扎锁口圈梁钢筋及预插竖向箍筋，构成钢筋支架，钢筋支架的外周面底部沿径向向外凸出构成加固凸起；在钢筋支架上设置预埋件；在锁口基槽中位于钢筋支架外侧支搭锁口圈梁模板，模板下压至少部分加固凸起；在预设第一圈环位置和预设第三圈环位置之间浇筑锁口圈梁混凝土；拆除锁口圈梁模板并换填级配砂夹石。钢筋支架上设置加固凸起，填充的级配砂夹石能够压住加固凸起，可提高锁口结构的稳定性。
