Fish-belly sill anchor-pulling supporting structure and construction method thereof
The invention relates to an anchor-pulling supporting structure, and particularly relates to a fish-belly sill anchor-pulling supporting structure which is convenient to stretch and draw, large in anchor rod distance and high in supporting capacity and a construction method thereof. The fish-belly sill anchor-pulling supporting structure comprises a foundation pit, anchor rods, a steel enclosing purlin and an enclosure plate; the enclosure plate is arranged on the inner side wall of the foundation pit; the anchor rods are inserted into the enclosure plate at intervals and stretch into the inner side wall of the foundation pit; the steel enclosing purlin is horizontally arranged on the enclosure plate; one of ends of the anchor rods is connected with the steel enclosing purlin; anchor assemblies are arranged on the steel enclosing purlin at intervals; a stretching and drawing base plate is arranged on each anchor assembly; steel strand anchors are arranged on the two sides of each stretching and drawing base plate. Steel strands are arranged between the steel strand anchors; and supporting rods connected with the steel enclosing purlin are arranged between every two adjacent anchor assemblies at intervals. According to the fish-belly sill anchor-pulling supporting structure, the tensile force of the anchor rods directly acts on the steel enclosing purlin between the anchor rods through the steel strands and the supporting rods, the transfer ratio of the tensile force of the anchor rods to the midspan of the steel enclosing purlin is increased, and the problem that the supporting force between the anchors is weak in an existing anchor-pulling supporting technology is solved.
本发明涉及拉锚支护结构，具体是一种张拉便捷、锚杆间距大、支护能力强的鱼腹梁拉锚支护结构和鱼腹梁拉锚支护结构施工方法。包括基坑、锚杆、钢围檩和围护板，围护板设在基坑的内侧壁上，锚杆间隔插在围护板上且伸入基坑内侧壁，钢围檩水平设在围护板上，锚杆一端与钢围檩连接，钢围檩上间隔设有锚具组件，锚具组件上均设有张拉垫板，张拉垫板的两侧均设有钢绞线锚具，钢绞线锚具之间均设有钢绞线，每两个相邻的锚具组件之间均间隔设有与钢围檩连接的撑杆。本发明通过锚杆的拉力经钢绞线和撑杆直接作用于锚杆间钢围檩，提高锚杆拉力向钢围檩跨中的传递比率，改善现有拉锚支护技术的锚间支护力薄弱的问题。
