Description

Upward inclined retaining wall for greening by filling plant growth bags in chain building frame

Technical Field

The utility model relates to a barricade especially relates to an inclined barricade that faces upward of bag afforestation is planted to filling in chain building frame.

Background

The ecological civilization construction is the fundamental and big idea of the perpetual development of Chinese nationality, the ecological prosperity is civilized and the ecological seniority is civilized and seniorized. The elevation slope type retaining wall belongs to one of gravity type retaining walls, and is applied to water conservancy project river channel treatment and highway slope treatment. The upward-inclined retaining wall is preferably adopted for the rock side slope and the soil side slope formed by excavation, and the heavy retaining wall or the upward-inclined retaining wall is preferably adopted for the soil side slope with larger height. Therefore, the upward inclined retaining wall has a wide application range. Most domestic researchers pay more attention to the stress calculation method, stability and application of the retaining wall, but no public report is found on how to endow the retaining wall with ecological functions. Most of the upward-inclined retaining walls are made of grouted stones or concrete materials, the side facing water is smooth and steep, the retaining walls are stiff and monotonous, ecological characteristics are lacked, and unfortunate people falling into water cannot climb to the shore along the wall surface, and if the retaining walls are used on a large scale, the retaining walls are not coordinated with the idea that people and nature are harmoniously symbiotic and green water mountains are trampled, namely the gold mountain and the silver mountain. However, the inclined retaining wall has unique advantages, such as less soil pressure on the wall back, and the wall back and the side slope of the excavated surface are jointed, so that the excavated volume and the backfill volume are small.

If the upward inclined retaining wall can be subjected to ecological transformation, a full-coverage ecological landscape can be formed on the water side of the retaining wall, and the method can help unfortunate drowning people to climb to the shore for self rescue, so that the method has important significance for meeting the increasing requirements of beautiful ecological water environment of people and comprehensively constructing a safe and green ecological water system. A slant-upward retaining wall for greening by filling plant growth bags in a chain building frame is provided.
