Gabion revetment mat ecological landscape stone embankment construction procedures and methods
????
????( A ) the construction procedure
???
?????Measured according to design drawings stakeout , first with excavator entire slope and slope excavation wall foundation trench excavation teeth , followed by pouring the concrete wall construction teeth , tooth wall construction is completed and after a certain time curing slope manually intensive , according to the design requirements of the laying of 150mm thick cushion and compacted sand and gravel , and then install the box gabion mats , artificial stone machinery loading , and finally tied closed lid and sow seeds, etc. .
???
????( 2 ) Construction Methods
???
??????a. lashing interval mesh . Artificial Lift gabion mats about a 90 °, lashing spacer mesh to become cabinet , lashing wire wire according to the design using the same material , double-stranded and twisted every 20cm interval lashing tight . Spacer mesh in the upper and lower four fixed and lashing twist tight.
?
??????b. laying gabion mats. Approved laying position, according to the design icon placed gabion mats. On the need to meet the overall design requirements , combined with the vertical direction , lashing all adjacent gabion borders, vertically down from the start with a wire around 2-3 laps after banding, gabion mats must be adjacent to the border line online lashing , in order to integrally coupled adjacent mat gabion box , each 20cm interval banding. Gabion mats box link before submitting cabinets filled .
 
????( 3 ) filled with pebbles
???
??????a. first with scaffolding fixed gabion mats, in order to avoid its deformation. Mechanically or manually pebbles filling, filling one stone shall fill a grid, to ensure that the gabion mat shape integrity. Each gabion filled spaces shall at the same uniform cobblestone to ensure gabion Founder . Stone according to the design requirements for acceptance, prohibited the use of rust stone , weathered stone , garbage stone , stone mesh size shall not be less than the diameter of 1.5 times the diameter of caulk except stone .
??
??????b. stone filling , first in the bottom with a diameter of 150 ~ 200mm of stone uniform furnishings , and then start from the four corners of the cages diameter of 250mm or so yards of stone masonry , stone and then level with the appropriate hierarchical furnishings, box filled with middle size , filling is completed fixed cabinet . When the filler during filling up the cabinet 1/4 , with a small gravel or sand filling vacancies , and once with the drill rod rammer compaction , adjust cabinet lines . Externally exposed parts shall assemble the artificial barrier , neatly packing density to beautiful. Based on the actual amount needed to set stretch .
??
????( 4 ) tied closed lid
???
?????Capping shall, before the top stone paved smooth, checking each cages filled with stone height , the height difference within ± 5cm , within ± 3cm length difference can Sizha steel wire tied closed lid , tied closed when the lid , from the bottom up , sealing edge connects closed, the box around the border again at 15cm spacing banding , are basically the same lines anyway , so that all cages together into a whole , on the river bank slope for the overall protection .
???
????( 5 ) mat gabion box above flood level and grass vegetation construction according to design requirements , good vegetation grass seed selection, cage cover , the gap should be filled with clay at the top 5cm clay fill up , and then sow seeds , and timely maintenance . Shop planting turf above flood level .
 
??????Gabion revetment mat landscape stone embankment Eco Urban Flood Control Project in Jiangxi Province, the first time in use , and achieved a good environment decorative effect. Gabion revetment mat landscape stone filling in the promotion of eco- energy saving, low-carbon , ecology, environmental protection concept of urban development today , with a very broad application space. The application shall be in practice, constantly sum up experience, in order to promote the use of other projects nationwide .
