One-step molded composite material flood prevention and emergency rescue boulder and preparation method thereof
The invention discloses a one-step molded composite material flood prevention and emergency rescue boulder and a preparation method thereof. The flood prevention boulder is composed of concrete, a reinforcement cage, a supporting plate, a ton bag and a gravel core. The boulder is in the shape of a regular quadrangular frustum pyramid, is good in integrity, high in density, large in size and good in durability, is difficult to wash away by water flow and can be well clamped at a root stone pile; the preparation method is simple, one-time forming is achieved, integrity is good, and batch manufacturing is facilitated; the preparation method comprises the following steps: firstly, manufacturing a compacted gravel core by using a ton bag; lowering a reinforcement cage and pouring bottom concrete to the top surface of the cushion block; hoisting ton bags and compacted sand and stone cores; covering a reinforcement cage cover, and pouring side wall and top concrete; and then curing is conducted, and finally preparation is completed.
本发明公开了一种一次成型的复合材料防汛抢险大块石及制备方法，该防汛大块石由混凝土、钢筋笼、托板、吨包和沙石芯组成。大块石的外形为正四棱台型，整体性好，密度大，体型大，耐久性好，难于被水流冲走且能较好地卡在根石堆处；制备方法简单，一次性成型，整体性好，便于批量制作；其制备方法与步骤包括：利用吨包首先制作压实的沙石芯；下放钢筋笼并浇筑底部混凝土至垫块顶面；吊装吨包及压实的沙石芯；盖上钢筋笼盖，浇筑侧壁和顶部混凝土；进行外模板脱模，然后养护最终制备完成。
