Construction method of lattice beam pre-stressed anchor cable side slope supporting formwork supporting system
The invention discloses a construction method of a lattice beam pre-stressed anchor cable side slope supporting formwork supporting system. The construction method comprises the steps that S1, surveying and setting out are conducted, drilling is conducted, holes are cleaned, anchor rods are manufactured and installed, grouting is conducted, and reinforcing ribs and anchor heads are welded; s2, binding an inner supporting rod, and installing a drain hole embedded pipe; s3, a lattice beam side formwork and a wallboard formwork are erected; s4, clamping wood is longitudinally nailed and fixed on the outer sides of the lattice beam side formwork, the bottom formwork and the wallboard formwork; s5, a plurality of sets of transverse steel pipes are transversely laid in the direction perpendicular to the wood clamping direction; s6, one opposite-pull screw rod penetrates through the position between every two sets of transverse steel pipes, and the transverse steel pipes are clamped and fixed through E-shaped clamps and nuts; s7, mutual anchoring base plates are clamped between the steel strands and the lattice beams and fixed through fixing pieces; s8, the steel strand of the mutual anchoring backing plate penetrates into an anchor plate of the pre-stressed anchor cable; s9, inserting pieces are symmetrically inserted between the mutual anchoring base plate and the anchor plate; and S10, concrete pouring. An inclined supporting mode is replaced, and the situation that stress control is difficult due to an ultra-long and ultra-high supporting mode is avoided.
本发明公开了一种格构梁预应力锚索边坡支护模板支撑体系施工方法，S1：测量放线、钻孔、清孔、锚杆制作安装、注浆、焊接加强筋和锚头；S2：绑扎内撑杆，安装泄水孔预埋管；S3：支设格构梁侧面摸板及墙板模板；S4：在格构梁侧模和底模、墙板模板外侧纵向钉固夹木；S5：在垂直于夹木的方向横向铺设多组横向钢管；S6：在每组横向钢管之间位置，穿入一根对拉螺杆，用山型卡和螺帽将横向钢管的位置行卡固；S7：在钢绞线与格构梁卡接有互锚垫板，并用固定件进行固定；S8：在:互锚垫板的钢绞线穿入预应力锚索的锚板；S9：在互锚垫板和锚板之间对称插入插件；S10：混凝土浇筑。本发明替代斜向支撑的方式，规避了超长超高的支撑方式带来的受力控制较难。
