Construction method for temporary protection of high and steep edge upward slope in collapsible loess area
The invention relates to a construction method for temporary protection of a high and steep edge front slope in a collapsible loess area. The construction method comprises the following steps: excavating an intercepting ditch; excavating an upward slope; driving an anchor rod; hanging a net; spraying concrete; and repeating the steps to carry out the next circulation construction. According to the construction method for temporary protection of the high and steep edge upslope in the collapsible loess area, a comprehensive anchoring method of the anchor rods, the metal net and the sprayed concrete is adopted, the sprayed concrete is used for protecting loess on the surface layer from being scoured, meanwhile, the metal net is added to improve the performance of the sprayed concrete, the construction method is simple, the construction cost is reduced, and the construction efficiency is improved. And the protection performance is effectively improved.
本发明涉及一种湿陷性黄土区高陡边仰坡临时防护的施工方法，包括以下步骤：开挖截天水沟；开挖仰坡；打锚杆；挂网；喷射混凝土；重复上述步骤进行下一个循环施工。本发明提供的一种湿陷性黄土区高陡边仰坡临时防护的施工方法采用锚杆、金属网和喷射混凝土的综合锚固方法，利用喷射混凝土保护表层黄土不被冲刷，同时增加金属网改善喷射混凝土性能，施工方法简单、并降低了施工成本，并有效提高了防护性能。
