Abstract

The invention relates to a construction method for a roadbed three-dimensional drainage strengthened ecological slope protecting structure. The construction method mainly comprises the steps of preparation of construction, construction of a high-pressure rotary grouting pile, excavation of foundation trenches, pouring of a concrete strip foundation, mounting of a prefabricated frame grid bottom protecting board, laying of tiepiece belts, laying of a first batch of geocell, building of a first layer of ecological bags and core grouting of vegetation concrete, filling of soil of wall backs and pressing, punning, self-compacting concrete grouting of a lower layer of a press top plate, mounting of prefabricated frame grid press top plates and guardrails, cleaning of the slope surface and spray-seeding of grass seed for greening. According to the construction method for the roadbed three-dimensional drainage strengthened ecological slope protecting structure, the slope structure stabilization, soil and water conservation and greening are completed in one time, and use of building materials with high energy consumption and high pollution can be reduced on a large scale.

Description

technical field [0001] The invention relates to an ecological slope protection structure, in particular to a construction method for a roadbed three-dimensional drainage reinforced ecological slope protection structure. Keeping and greening done in one go. It belongs to the field of highway engineering and is suitable for slope protection of railways, highways, rivers, lakes, mines and mountains. It can also be used in municipal engineering, three-dimensional greening landscape walls in urban residential areas, etc. Background technique [0002] In recent years, with the rapid development of my country's economy, the traffic volume of roads has increased year by year. In the construction of expressways, it is often necessary to excavate a large number of slopes, which will destroy the original vegetation cover, resulting in a large number of secondary bare land and serious The phenomenon of water and soil erosion caused a serious imbalance in the ecological environment.
