Problems solved by technology

[0002] With the implementation of my country's sustainable economic development strategy, a large amount of investment and implementation of infrastructure such as road subgrades will inevitably cause damage to the original ecological environment during the construction process, especially in excavated road sections with poor soil conditions and rocky slopes. Due to the lack of foundation for plant growth, engineering protection measures such as mortar rubble slope protection or hanging net anchor spraying are often used. Not only the destroyed vegetation cannot be restored, but also the ecological environment and landscape effect of the road are affected.

specific Embodiment

[0027] A construction method for roadbed excavation and slope protection with framed beams and stacked planting bags for greening, comprising the following steps: construction preparation—cleaning and leveling the slope—layering of framed beams with elastic lines—soil preparation—filling with vegetation The preparation of the base material - filling the planting bag with the base material - stacking the planting bag - installing the angle steel to fix it - laying the non-woven fabric - spraying water for maintenance - survival rate and test results.

[0028] In the construction preparation, the outsourced testing of water and soil tests and the ordering of planting bags should be completed first, and the screening of plant substrate peat soil and sawdust should be completed at the same time for later soil improvement.

[0029] In the cleaning and leveling of the slope surface, loose stones and other sundries on the slope surface are removed, so that the slope surface reaches th...

Abstract

The invention discloses a construction method for road embankment excavation slope sash beam slope protection stacked seed-nutriment-soil sack greening. The construction method comprises the following steps of construction preparation, slope cleaning and flattening, sash beam snapline layering, soil preparation, preparation of seed-nutriment-soil sack filling base materials, base material loading of seed-nutriment-soil sacks, seed-nutriment-soil sack stacking, angle steel installation for fixing, non-woven laying, water spraying maintaining, a survival rate and detection results. Greening slope fixing experimental researches are carried out through the construction method of greening of stacking seed-nutriment-soil sacks in excavation slope sash beams, engineering slope protection and plant ecological slope protection are combined, the method suitable for road embankment excavation slope greening protection is formed, the stability and the greening effect of an excavation slope are effectively enhanced, and stability and long-time greening of soil barren roads, soil-rock or weathered stone road slopes of the excavation slopes is successfully achieved.

Description

technical field [0001] The invention belongs to the field of road construction, and in particular relates to a construction method for road embankment excavation side slope frame lattice beam slope protection and stacking planting bags for greening. Background technique [0002] With the implementation of my country's sustainable economic development strategy, a large amount of investment and implementation of infrastructure such as road subgrades will inevitably cause damage to the original ecological environment during the construction process, especially in excavated road sections with poor soil conditions and rocky slopes. Due to the lack of foundation for plant growth, engineering protection measures such as masonry rubble slope protection or hanging net anchor spraying are often used. Not only the destroyed vegetation cannot be restored, but also the ecological environment and landscape effect of the road are affected. Therefore, how to ensure the stability of excavated...
