Abstract
A vegetation separating wall with earth lattices is provided. A strengthening rib filled with filling material inside is provided on the road foundation, earth lattices filled with soil is provided at the lateral side of the road foundation and above and below the strengthening rib, and one layer of earth lattices is anchored with the adjacent upper and lower layers of earth lattices. Compared with the existing separating wall of road foundation, the separating wall in the utility model belongs to flexible separation structure, has both characteristics of concrete or stone work separating wall and reinforced soil separating wall, can well harmonize the stress and deformation of the wall; meanwhile, the wall can effectively disperse the stress of the road foundation, so as to reduce settlement. The vegetation separating wall with earth lattices has the advantages of light weight, standard specification, and easy construction. Under the prerequisite of stability, flower and grass can be planted in the earth lattices to green the sloping surface and beautify environment. The utility model can be widely used in road foundation separating wall, water reservoir dike dam and riverbank.
Description
Technical field
The utility model belongs to the retaining wall technical field, is specifically related to retaining wall or protecting wall.
Background technology
Propping up the retaining structure is engineering measure commonly used in the civil engineering, and main purpose is to carry out the stability that roadbed props up retaining, protection and guarantees roadbed.But the metope of existing retaining structure all is to be formed by concrete or stone-laying body, causes very big difficulty for the recovery of ecological environment, and is very inharmonious with surrounding environment, influenced geomorphologic landscape, and environment protecting is unsatisfactory.
Geotechnical grid is a kind of novel geosynthetics of developing the eighties in 20th century, and it is the material of the 3-D solid structure system that formed through ultrasonic bonding by the high density polyethylene (HDPE) of several reinforcements or polypropylene broadband.Geotechnical grid vegetation barricade is according to the architectural characteristic of geotechnical grid, utilizes the frictional force of lattice chamber and filler and lattice chamber self to the lateral restriction of filler and big, the anticorrosive ageing-resistant deck of bulk strength height, rigidity that forms.
Summary of the invention
Technical problem underlying to be solved in the utility model is to overcome the shortcoming of above-mentioned roadbed barricade, provide that a kind of structure is light-duty, specification standards, easy construction, applicability are wide, can coordinate preferably body of wall stressed with distortion, and the geotechnical grid vegetation barricade that can on barricade, plant flowers and plants.
Solving the problems of the technologies described above the technical scheme that is adopted is: establish on roadbed and fill Packed reinforcing rib within it, be filled with native geotechnical grid in its lattice being located at up and down of the side of roadbed reinforcing rib, one deck geotechnical grid connects with holdfast with neighbouring one deck geotechnical grid.
Geotechnical grid of the present utility model is 3 D stereo net structure or three-dimensional honeycomb structure.
The height of geotechnical grid of the present utility model is 15～25cm.
The cross section of geotechnical grid of the present utility model is prismatic or the regular hexagon that area equates, the volume of each lattice of geotechnical grid is 0.024～0.04m
3
The filler of filling in the reinforcing rib of the present utility model is gravel or rubble.
The utility model is compared with existing highway subgrade barricade, and barricade of the present utility model belongs to flexible retaining structure, has the characteristics of concrete or stone-laying barricade and reinforced earth bulkhead concurrently, can coordinate the stressed of body of wall and distortion preferably, simultaneously, can disperse base stress effectively, sedimentation is less.The geotechnical grid vegetation wall-retaining structure that it adopts has advantages such as in light weight, specification standards, easy construction, is guaranteeing can to plant flowers and plants under the stable prerequisite in geotechnical grid, and it is domatic to reach greening, beautifies the environment.Can on roadbed barricade and reservoir dam and river levee, extensively promote the use of.
