Novel protection structure for side slope of earthquake-prone zone
The invention discloses a novel protection structure for a side slope of an earthquake-prone zone. Slope surface protection and slope body reinforcement of the side slope is realized by coordinating and combining an initiative protective net and a pre-stressed anchor cable, and an energy dissipation device is internally provided to allow certain displacement deformation during an earthquake so as to realize an earthquake-resistant function, the invention provides performance parameters and geometric parameters of the energy dissipation device, key construction steps of the protection structure are provided, anchor holes of pre-stressed anchor cables are positioned and drilled, meanwhile anchor cables and anchor bundles of the anchor cables are manufactured, an SNS initiative protective network is laid and the SNS initiative protective network is fixed by adopting short anchor rods, the anchor cable and anchor bundles are anchored to a drill hole, a steel casing used for dividing the anchor bundles and a hard rubber gasket (plate) is installed, the rubber gasket (plate) is installed, pre-stressed anchor cable anchorage piers are constructed and tensioning equipment are constructed in place, the position of the initiative protective network is adjusted, the anchor cable is tensioned and the anchor is sealed, and finally, the initiative protective net is adjusted, tensioned and fixed.
本发明公开了一种地震多发带边坡新型防护结构，该结构通过协调组合主动网和预应力锚索，实现边坡的坡面防护和坡体加固，并在结构中设置消能装置，允许地震时发生一定的位移变形，实现抗震功能。本发明提出了消能装置的性能参数和几何参数。提出了防护结构的关键施工步骤，进行预应力锚索锚孔定位并实施钻孔，同时制作锚索锚束；SNS主动网铺设并采用短锚杆固定；锚索锚束下锚至钻孔，并安装用于分割锚束和硬橡胶垫片(板)的钢护筒；安装橡胶垫片(板)；施作预应力锚索锚墩及张拉设备就位；调整主动网位置；张拉锚索并封锚；最终调整主动网并张紧固定。
