The invention discloses a construction method for a spray head layer of a bailey frame type prilling tower, which comprises the following steps: selecting a bailey frame as a spray head layer support, pre-assembling the bailey frame on the ground, and forming an integral bailey frame 22 truss adaptive to the diameter of the inner wall of the prilling tower by using basket type bailey pieces through high-strength steel pins; the eight Bailey trusses in the middle are assembled into a whole and hoisted to a prilling tower slip form platform, and the whole and the prilling tower slip form platform form a whole; slip form construction is conducted to the supporting position, embedded parts are embedded, steel corbels are welded to the embedded parts, and the bailey truss is placed on the steel corbels through chain hoists and fixed by welding limiting plates; the bailey trusses are expanded, the rest 14 bailey trusses are assembled, a safety flat net is laid after assembly is completed, and steel springboards are laid on the tops of the bailey trusses; and nozzle layer stiff steel beams are assembled and installed, reinforcing steel bars are bound, formworks are installed, and concrete is constructed. The bailey truss is used as a construction support of the nozzle layer of the granulation tower, so that the construction preparation period is shortened, the construction safety is improved, and the use of large hoisting equipment is reduced.
本发明公开了一种贝雷架式造粒塔喷头层施工方法，选择贝雷架为喷头层支撑，贝雷架地面预组装，用高强钢销将花篮式贝雷片组成适应造粒塔内壁直径的整体贝雷架22榀；组装中部的8榀贝雷架成一个整体并吊装至造粒塔滑模平台，与滑模平台组成一个整体；滑模施工至支撑位置，预埋预埋件，在预埋件处焊接钢牛腿，利用手动葫芦将贝雷架放置于钢牛腿上并焊接限位板固定；对贝雷架进行扩展，将剩余14榀贝雷架进行组对，组对完成铺设安全平网，贝雷架顶满铺钢跳板；喷头层劲性钢梁组对安装，钢筋绑扎、模板安装、混凝土施工。本发明利用贝雷架作为造粒塔喷头层施工支撑，缩短施工准备周期，施工安全性得到提高，减少大型吊装设备的使用。
