干砌片石和混凝土砌块护坡
干砌片石和混凝土砌块护坡
Dry Block Stone and Concrete Block Slope Protection
用于坡面有涌水、坡度小于1:1,高度小于3米的情况,涌水较大时应设反滤层,涌水很大时最好采用盲沟。
When there is water gushing on the slope, the gradient is less than 1:1 and the height is less than 3 meters, the filter layer should be set up when the water gushing is large, and the blind ditch is the best choice when the water gushing is large.
防止没有涌水的软质岩石和密实土斜坡的岩石风化,可用浆砌片石和混凝土护坡。坡度小于1:1的用混凝土,坡度1:0.5~1:1的用钢筋混凝土。其中浆砌片石护坡可以防止岩石风化和水流冲刷,适用于较缓的坡。
To prevent the weathering of soft rock and compact soil slopes without water gushing, masonry and

Concrete with slope less than 1:1 and reinforced concrete with slope 1:0.5-1:1. Among them, masonry flagstone slope protection can prevent rock weathering and water erosion, and is suitable for gentle slopes.
格状框条护坡是用预制构件在现场装配或在现场直接浇制混凝土和钢筋混凝土,修成格式建筑物,格内可进行植被防护。
Lattice frame slope protection is a kind of building which is assembled by prefabricated components or cast concrete and reinforced concrete directly in the field. It can be used for vegetation protection in the lattice.
有涌水的地方干砌片石。为防止滑动,应固定框格交叉点或深埋横向框条。
Dry block stones where there is water gushing. In order to prevent sliding, the crossing point of frame or deep buried transverse frame should be fixed.
在基岩裂隙小,没有大崩塌发生的地方,为防止基岩风化剥落,进行喷浆或喷混凝土护坡。若能就地取材,用可塑胶泥喷涂则较为经济,可塑胶泥也可做喷浆的热层。注意不要在有涌水和冻胀严重的坡面喷浆或喷混凝土。
In order to prevent weathering and spalling of bedrock, grouting or shotcreting is used for slope protection where there are small fissures in bedrock and no major collapses. If local materials can be obtained, it is more economical to spray with plastic mud. Plastic mud can also be used as the hot layer of spraying. Be careful not to spray grouting or concrete on slopes with severe water gushing and frost heaving.
