Description
Technical field
The invention belongs to the technique of design and construction field of civil engineering soft foundation road structure, and in particular to Yi Zhong
The construction method of road is built on reclaimed ground.
Background technology
Recently as the fast development of China's port construction, the not enough phenomenon of land resource becomes increasingly conspicuous, reclaiming land around sea
Have become the important means that most of port cities now solve industrial land.
Requirement in terms of for land reclamation, moistureproof wave resistance and transport, it is necessary to sea gear is built on barged-in fill, enclose low bank between fields and
Road.Conventional method needs the ground engineering materials such as a large amount of outward transport Extra-fine sands, mountain skin soil, block stone.These ground materials exploitation, transport with
And construction both caused environmental disruption to the collecting location of material, and ocean is polluted and destroyed, simultaneously.Quantities
Greatly, it is costly.Therefore, in order to reduce cost, environmental protection, it is necessary to research and develop a kind of method of new road construction.
The content of the invention
Applying for road is built on reclaimed ground it is an object of the invention to overcome the deficiencies of the prior art and provide a kind of
Work method.
The present invention is achieved by the following technical solutions：
A kind of construction method that road is built on reclaimed ground, it comprises the following steps：
Step one：Surface pond is discharged, is worked on former mud face (0) based on laying chaste tree basketry or bamboo sheathing or netted bamboo raft
Bed course (1), sump under casing (2), and vertically-mounted sump adapter (3) are laid according to sump well location situation；
Step 2：One layer of geotechnological non-woven fabrics (4) is laid on working cushion layer (1), and sump is taken over (3) through geotechnique
The reserved sleeve (5) of non-woven fabrics；
Step 3：One layer of three-dimensional composite drainage network (6) is laid on geotechnological non-woven fabrics (4), and sump is taken over (3) and is worn
Cross the reserved sleeve (7) of three-dimensional composite drainage network (6)；
Step 4：One layer of geomembrane bag (8) is laid on three-dimensional composite drainage network (6), then to first layer geomembrane bag
(8) filling first layer muck soil (9) in；Sump carries out draining, after first layer mud (9) consolidation forms some strength,
Then repeat step three and step 4, proceed new one layer three-dimensional composite drainage network laying 6 and geomembrane bag laying, and fill
Muck soil, until constructing to default top mark eminence；
Step 5：The geotechnological non-woven fabrics overcoat (10) of one layer of laying on top geomembrane bag, it is ensured that non-woven fabrics is protected
Layer (10) covers whole basal plane, and by its edge embedded soil body；
Step 6：Layer of sand (11) is laid on non-woven fabrics overcoat (10), vertical plastic draining board (12) is then set, moulded
Drain bar bottom is expected deeply to reclaimed ground layer, and plastic draining board (12) wrench is buried in layer of sand (11)；
Step 7：Mountain skin soil structure layer (13) is laid on layer of sand (11)；
Step 8：Preloading load (14) is successively laid on mountain skin soil structure layer (13), and carries out sump draining；Work as change
By preloading load (14) removal when shape condition meets engineering demand, stop sump draining；
Step 9：Slope shoulder (15), and sub-surface of constructing (16) and road surface are built in construction by laying bricks or stones on mountain skin soil structure layer (13)
Surface layer (17), road structure is completed.
In the above-mentioned technical solutions, sump adapter is ferrous material, and carries out preservative treatment, and merogenesis is installed, and is gathered many
Individual draining hole, outer attached non-woven fabrics filtering layer；Sump under casing is cavity box-like body, and waterproof, top is open, and inside sets diving
Pump and discharge pipe line；Sump adapter bottom end seal is arranged on sump under casing, and discharge pipe line is drawn into sump adapter,
So as to constitute sump drainage system.
In the above-mentioned technical solutions, the muck soil collection in geomembrane bag is from local weak soil of constructing, so that more
Convenient, economic, environmental protection；When filling muck soil, mud can be added according to soil nature and fall the reagent that becomes silted up, accelerate to fall to become silted up, if once filling
When degree of filling out is not enough, 2 fillings can be divided, thickness requirement is met；According to soil strength growth pattern, typically need to enter for 3 days~7 days
The three-dimensional composite drainage network laying of row last layer and geomembrane bag laying.
The subgrade strengthening structure formed in above-mentioned work progress：Laid on former mud face on working cushion layer, working cushion layer according to
It is secondary to be equipped with film bag layer of the multilayer filled with muck soil, and it is provided with three-dimensional composite drainage network between each film bag layer；Most
Laid on the film bag layer of top layer and vertical plastic draining board has been set below layer of sand, layer of sand, plastic draining board bottom is deeply to hydraulic reclamation
Soil basic unit, plastic draining board (12) wrench is buried in layer of sand (11)；Erected in film bag layer, three-dimensional composite drainage network, layer of sand
Directly it is provided with sump；Laying preloading load layer on mountain skin soil structure layer, mountain skin soil structure layer is laid on layer of sand.
The advantages of the present invention are：
1, it is logical as transverse drainage by the use of the three-dimensional composite drainage network between each film bag layer during laying film bag layer
Road, the moisture after film bag layer is pressurized in its internal muck soil is discharged, and the moisture of discharge is horizontal along three-dimensional composite drainage network
It is collected to inside sump, is then discharged the water in sump using immersible pump, so that quickly reduction film bag layer muck soil
Water content, preliminary hard road structure is formed on barged-in fill upper strata；
Then, set deep layer plastic draining board, lay layer of sand, and by setting surcharge preloading load, to film bag layer and blow
Filled up ground applies pressure, further to promote discharge and the row of reclaimed ground moisture of the filling silt soil moisture in film bag
Go out；During draining, plastic draining board can enter modeling as vertical drainage passage, the moisture of reclaimed ground and the moisture of muck soil
Expect drain bar, the moisture of plastic draining board is laterally collected to inside sump (because of three by layer of sand and three-dimensional composite drainage network
Due to setting deep layer plastic draining board local stoppages may occur for the transverse drainage passage of dimension composite drainage network, so in plastics
Layer of sand is set, and layer of sand is used as transverse drainage passage, it is ensured that the moisture of plastic draining board is horizontal along layer of sand on drain bar wrench
It is collected to sump), then the water in sump is discharged using immersible pump, so as to realize simultaneously to film bag layer and deep layer hydraulic reclamation
Soil base is reinforced.
2, the muck soil collection in geomembrane bag from local weak soil of constructing so that more facilitate, economic, environmental protection.
3, sump reduces water level, and water level is located at the three-dimensional composite drainage network position of bottom, make in filling film bag the soil body and
The effective stress increase of bottom foundation soil body, effective reinforced load increase.
4, by the filling muck soil in geomembrane bag, film bag has effectively blocked water body supplement passage, reduces periphery water
Adverse effect of the body to the soil body in filling film bag.
5, three-dimensional composite drainage network can promote to catchment when filling the lower section integrate draining of film bag using the self gravitation of water
(i.e. the water of the soil body is flowed downwardly into three-dimensional composite drainage network by self gravitation in film bag), need gram when being different from draining in traditional precompressed
Take the self gravitation of water.
6, construction method of the invention can directly be constructed on reclaimed ground, there is good adaptability.
