Underground station axillary corner impermeable structure
The invention relates to the field of underground station construction, and in particular, relates to an underground station axillary corner impermeable structure which comprises a protective layer, awaterproof layer and a sliding layer. The waterproof layer is formed by attaching a waterproof coiled material to the outer portions of a bottom plate and side walls, the waterproof coiled material is cheap and easy to obtain, and the waterproof effect is good. The sliding layer is butter coating the waterproof coiled material, and the sliding layer can reduce the constraint of an enclosure structure and the foundation on a concrete-based material at axillary corners during forming and reduce the shrinkage stress during forming. An anti-cracking reinforcing mesh is arranged in the concrete protective layer, the built-in reinforcing mesh can increase the concrete tensile strength of the axillary corners, and concrete cracking can be more effectively prevented. The raw materials of the concrete used at the axillary corner impermeable structure are matched with the design, so that certain choices are provided for crack resistance, and the temperature stress and shrinkage stress of the concrete are reduced as much as possible. The technology has been applied to construction of Shenzhen Gangxia North transportation hubs, the application effect is good, axillary corner cracking is reduced by 90% or above, and good social benefits and economic benefits are obtained.
本发明涉及地下车站施工领域，更具体地说，它涉及一种地下车站腋角抗渗结构，其包括保护层、防水层和滑动层。防水层为防水卷材贴附在底板和边墙外部，防水卷材廉价易得，防水效果好。滑动层为涂覆在防水卷材上的黄油，滑动层能够减小围护结构与地基对腋角处砼基材料成型时的约束，减小成型时的收缩应力。混凝土保护层内设置有抗裂钢筋网片，内置钢筋网片能够增加腋角的混凝土抗拉强度，能够更加有效阻止砼开裂。本发明腋角抗渗结构处用的混凝土的原料、配合设计对抗裂性能均有一定选择，尽量降低混凝土的温度应力和收缩应力。本发明技术曾经应用于深圳岗厦北交通枢纽建设，应用效果良好，降低腋角开裂90%以上，获得良好的社会效益和经济效益。
