Slope protection materials commonly used in gardens
在园林中常用的护坡材料包括石笼、草皮、块石和预制框格等。
The commonly used slope protection materials in gardens include stone cages, turf, block stones and prefabricated frames.
一、石笼护坡
1. Stone cage revetment
石笼内抛填厚度为0.2-0.4m的块石,块石下设厚度为10-20cm的砾石层以利于排水和减少土壤流失。
The gravel layer with thickness of 10-20 cm under the stone cage with the thickness of 0.2-0.4 m is helpful to drainage and reduce soil loss.
二、植被护坡
Two. Slope protection by vegetation
采用草皮护坡方式的,植被层厚度为15-45cm,用花坛护坡的,植被层厚度为25-60cm,用灌木丛护坡,则灌木层厚度为45-180cm。植被层一般不用乔木做护坡植物,由于乔木重心较高,有时因树倒而造成坡面坍塌。
The thickness of vegetation layer is 15-45 cm, that of flower beds is 25-60 cm, and that of shrubs is 45-180 cm. xiniji.75ix.comfeiqi.75ix.comshusongjik.75ix.comtuoliubeng.75ix.comshalibeng.75ix.com hunliu.75ix.comThe vegetation layer generally does not use trees as slope protection plants, because the tree center of gravity is higher, sometimes the slope collapses because of the collapse of trees.
三、块石护坡
Three. Block stone revetment
护坡石料要求密度大、吸水率低和较强的抗冻性,如砂岩、花岗岩、石灰岩等岩石,以长宽比小于2:1,块径为18-35cm的长方形石料最佳。
Slope protection stone requires high density, low water absorption and strong frost resistance. For sandstone, granite, limestone and other rocks, rectangular stone with length-width ratio less than 2:1 and block diameter of 18-35 cm is the best.
四、预制框格
Four. Precast frame
由混凝土、塑料、金属网、铁件等材料制作的,其每一个框格单元的规格大小和设计形状都可以有许多变化。框格一般是预制生产的,在边坡施工时再装配成各种简单的图形。用锚和矮桩固定后,再往框格中填满肥沃土壤,土要填得比框格高,并稍稍拍实,防止下雨时流水渗入框格下面,冲刷走框底泥土,使框格悬空。
Made of concrete, plastics, metal mesh, iron and other materials, the size and design shape of each frame unit can vary greatly. Frames are usually prefabricated, and then assembled into various simple graphics during slope construction. Fixed with anchors and short piles, and then fill the frame with fertile soil. The soil should be filled higher than the frame, and slightly photographed to prevent water from seeping under the frame when it rains, scouring away the soil at the bottom of the frame and making the frame suspended.
