It is poured on 19 and widens base 18, widened base 18 and connect with former base layer 16 in entirety, poured above widening subgrade and widen road surface
17, it widens road surface 17 and is linked to be entirety with former road surface 15, widening base 18 and widening 17 outside of road surface and pour protection body 20 prevents from opening up
Wide base 18 comes down with road surface 17 is widened.
Above-mentioned EPS light road banks are widened the construction method in conjunction with plant biological bag protective slope structure and are included the following steps：
Step 1,2 Slope Treatment of former embankment is reinforced：The vegetation in 2 side slope of former embankment and protective slope structure are removed, according to
The geometric dimension and making mode of EPS light blocks 1,10 thickness of armoured concrete slab and installation position etc. cut open 2 side slope of former embankment
It is cut into the excavation face 3 of the step shape of certain altitude and width, manual amendment is simultaneously tamped, on the vertical plane of step, corresponding EPS
1 horizontal inter-layer position of light block is implanted into anchor pole 9, and slip casting forms anchor bolt grouting body 35 using drill hole of drilling machine, flattens earth's surface, and
The gutter 8 of 0.8~1.0m depths is excavated on the outside.
Step 2, TGXG 5 is fixed, graded soil hardcore 4 is laid with：9 revealed section of anchor pole passes through U-shaped connecting plate 21
5 grid hole of anchor pole through hole 31 and TGXG is used in combination location nut 34 to fix, patch U-shaped connecting plate 21 in 5 one end of TGXG
It fixes, the earth and stone material in 5 other end anti-package graded soil hardcore 4 of TGXG, after the completion of graded soil hardcore 4, builds by laying bricks or stones
Pitched work 7.
Step 3, bottom EPS lightweights widen layer construction, and exposed anchor pole 9 is passed through double end threaded sleeve with reinforcing bar 37 is connect
22 integrated connections are inserted into the reinforcing bar fixes sleeve 29 of single head connector 28 in connection reinforcing bar 37 after the completion of connection, according to reality
1 making of EPS light blocks fixes position of the single head connector 28 on connection reinforcing bar 37 apart from size with location nut, has positioned
Cheng Hou, the connecting hole 30 that connecting plate 40 is inserted into fixing bolt are fixed, and 11 making of intermediary water silt particle pulp layer is carried out after installation is complete,
Since fixing bolt is longer, fixing bolt reserves 2cm linkage sections when interlayer 11 making of cement sand bed, 1 bottom of EPS light blocks
The connecting hole 38 in portion, which is put into fixing bolt and reserves 2cm linkage sections, to be disposed, and vertical cement mortar joint filling 14 between pour.
Step 4, middle layer EPS lightweights widen layer construction, and installation middle layer connects reinforcing bar 37, and pacifies on connection reinforcing bar 37
Filling double-headed connector 39, the connecting plate 30 of 39 lower part of double-headed connector is widened layer with lower layer EPS lightweights by fixing bolt and is connect,
Fixing bolt is set on the connecting plate 30 at 39 top of double-headed connector, using the identical mode making interlayer cement bonded sand of step 3
Pulp layer 11 is laid with EPS light blocks 1 and pours vertical cement mortar joint filling 14.
Step 5, one layer of EPS lightweight of often constructing widens layer, the 4 layers of EPS lightweights that see whether continuously to have constructed widen layer or
Whether the EPS lightweights continuously constructed widen layer height more than 2m, judge whether to need pouring reinforcement concrete plate 10, and root with this
Judge whether to need bank protection according to actual conditions, if only needing bank protection, carries out step 6.1, if only needing to be laid with armoured concrete slab,
Step 6.2 is carried out, if desired bank protection and laying armoured concrete slab, carry out step 6.1 and 6.2 successively, if all not needing, repeat
Step 4.
Step 6.1, m esh-hanging sprayed concrete layer 12 is constructed, and EPS lightweights, which are widened, is laid with bar-mat reinforcement 23 on the outside of layer, and in reinforcing bar

Fixing bolt, making interlayer cement sand bed are installed in the connection hole of part, and fixing bolt exposes interlayer cement mortar layer surface, layer
Between the EPS light blocks of bottom are laid on cement sand bed, being exposed to the fixing bolt of interlayer cement mortar layer surface, to be inserted into EPS light
Mass pours vertical cement mortar joint filling；
(4) middle layer EPS lightweights widen layer construction, and installation middle layer connects reinforcing bar, and the installation double end connection on connection reinforcing bar
Part, the connecting plate of double-headed connector lower part is widened layer with lower layer EPS lightweights by fixing bolt and is connect, at the top of double-headed connector
Connecting plate on fixing bolt is set, using the identical mode making interlayer cement sand bed of step 3, be laid with EPS light blocks and
Pour vertical cement mortar joint filling；
(5) one layer of EPS lightweight of often constructing widens layer, judges whether to need bank protection and is laid with armoured concrete slab, if only needing to protect
Slope carries out step 6.1, if only needing to be laid with armoured concrete slab, carries out step 6.2, if desired bank protection and laying reinforced concrete
Native plate carries out step 6.1 and 6.2 successively, if all not needing, repeats step 4；
(6.1) EPS lightweights, which are widened, is laid with bar-mat reinforcement on the outside of layer, and embedded ribs are welded on bar-mat reinforcement, and gunite concrete, which is formed, to be hung
Net shotcrete layer, embedded ribs expose m esh-hanging sprayed concrete layer, are successively laid with banket soil engineering bag and three-dimensional water discharge coupling button,
The soil engineering bag that bankets near m esh-hanging sprayed concrete layer is connect by embedded ribs with m esh-hanging sprayed concrete layer；
(6.2) one layer of armoured concrete slab of cast in situs；
(7) it uses the identical method of step 3 to complete top layer EPS lightweights and widens layer construction, and widen in top layer EPS lightweights and poured on layer
Build one layer of armoured concrete slab；
(8) top subgrade construction, including pour and widen filler, widen base, protection body and widen road surface.
10. EPS light road banks according to claim 9 widen the construction method in conjunction with plant biological bag protective slope structure, feature
It is：In the step 5, when EPS lightweights are widened, layer has constructed 4~5 layers or EPS lightweights are widened the mounting height of layer and reached
When 2m, pouring reinforcement concrete plate is needed.
