As Hunan province first section implementation “ two type ” technology demonstration of under construction Eway, long Xiang high speed the construction units in project construction process in the actively active used meet two type concept of advanced technology, used bamboo grid method for green construction is optimization technology representative one, by application this more for Hunan local environmental green construction of new technology, power “ two type ” long Xiang high speed construction.
the so-called bamboo grid method, is along the road slope, surface horizontal bamboo Cross-and-drop, forming one canal cut, applies to slope no steeper than 1:0.75 of soil, soil slope of stone, wind and petrochemical.
bamboo grid method, in highway slope, along the surface transverse horizontal bamboo-and-drop, forming one stop-and-ditch
it is learned that, compared with the traditional method of planting bag, bamboo grid method has obvious advantages. Selects material conveniently during construction, local bamboo for the raw materials to complete the greening. While, planting soil directly contact, plant roots easy tied into slope surface, anti-rain scour ability strong, both can effective prevent slope surface soil erosion, while Bamboo tablets itself in meet vegetation recovery of Foundation Shang, years Hou also can degradation, formation organic matter fertilizer, no pollution, meet “ resources savings ”, and “ environment friendly ” of “ two type ” construction concept, is a ecological environmental of science method. At present, this new process is long Xiang high-speed line application step by step.
