Protective device for asphalt concrete core wall construction and using method
The invention provides a protection device for asphalt concrete core wall construction and a using method. The protection device comprises two rows of fixed steel chisels and covering canvas. The lower section of a drill rod of each fixed steel drill is anchored into a transition material on the outer side of the asphalt concrete core wall, and lug rings are fixed to the upper section of the drill rod at equal intervals in the axial direction; the side edge of the covering canvas is provided with two rows of hole sites, the two rows of hole sites are fixed on two rows of lug rings of the steel chisel, the covering canvas is provided with a row of air holes, the top of the covering canvas is covered with a layer of air inflation film with air inflation holes, and the periphery of the air inflation film and the covering canvas are connected into a whole to form an air bag structure. The beneficial effects of the invention are that the fixed steel chisel and the covering canvas are firmly connected and fixed through the two rows of hooks, switching of windproof, rainproof, dustproof and sunshade functions can be completed, and the influence of environmental factors is reduced. After the air bag structure is inflated and expanded, an arched structure can be formed at the top of the covering canvas, water accumulation is avoided, airflow is sprayed out of the air outlet holes, and the air flowing speed of the asphalt surface layer is increased.
本发明提出一种沥青混凝土心墙施工的防护装置及使用方法，包括两排固定钢钎以及遮盖帆布；每个固定钢钎的钎杆下段锚入沥青混凝土心墙外侧的过渡料内，钎杆上段沿轴向等间距固定有耳环；遮盖帆布的侧边开设有两排孔位，两排孔位固定钢钎的其中两排耳环上，遮盖帆布上开设有一排出气孔，遮盖帆布的顶部覆盖有一层带充气孔的充气膜，充气膜的四周与遮盖帆布连为一体形成气囊结构。本发明的有益效果：固定钢钎与遮盖帆布之间通过两排挂钩连接固定牢固，可以完成防风、防雨、防尘、遮阳功能的切换，降低环境因素影响。气囊结构充气膨胀后可以在遮盖帆布顶部形成拱起的结构，避免形成积水，气流从出气孔喷出，增加沥青面层的空气流动速度。
