攀檐式棚峒是悬臂式棚峒的一种型式,其主要结构是由内墙、悬臂版及平衡重(圬工或填土)所组成。由于其整体性较差,故一般仅适用于有小量塌方或堕石的地方;或因地形限制,外侧地基不良不能设置明峒或圩埸棚时采用。××攀檐式棚峒位于已成峒深挖路堑内,是明峒进口的一部分,全长十五米。该段路堑的地质情况:上部复盖坡积碎石层厚13～18米,其下为台地卵石层和基岩。碎石土成份以片岩为主,卵石土成份有石英岩、片麻岩、花岗岩、片岩等。片岩风化破碎颇严重,节理发达,f=3,其中72米一段岩石风化较重,节理发达,石质破碎,有发生塌方的可能,所以这一段设置了拱式明峒。明峒的进口,15米范
A type of cantilever roof canopy, the main structure of which is composed of an interior wall, a cantilever plate and a counterweight (masonry or earth fill). Because of its poor overall, it is generally only applicable to a small amount of landslides or landslides; or because of terrain constraints, the outside of the foundation can not be set bad Fairy or fairy shed used. × × climbing Yan-style shed 峒 has become a deep dig cut, is a part of Ming 峒 imports, a total length of 15 meters. The section of the geological conditions of the cutting: the upper cover slope gravel layer thickness of 13 to 18 meters, which is under the table pebble bedrock and bedrock. Crushed stone components to the main schist, pebble soil components quartzite, gneiss, granite, schist and so on. The weathering and crushing of schist was quite serious. The joints developed, f = 3, of which 72 meters a section of rock weathered heavier, developed joints, stone broken, there may be landslides, so this section set the arch Ming. Ming 峒 imports, 15 meters
