Description
Technical field
The invention belongs to reinforced earth technology field, more particularly to a kind of Geogrid Reinforced Earth Retaining Wall based on architecture sediment
Structure and its construction method.
Background technology
At present, with the acceleration of urbanization process, construction industry is also simultaneously fast-developing, the construction of road, the excavation of foundation ditch,
The quantity of architecture sediment is especially huge caused by construction of subway etc. is annual.Due to containing more cohesive soil in architecture sediment,
Discharging consolidation can be caused difficult, so it can neither be used for regeneration aggregate, regeneration filler can not be used for.The processing of dregs at present
Mode is essentially filled and stacked, so as to cause greatly to endanger to environment and can increase follow-up processing cost.2015
December, the red col dregs receiving field in Shenzhen light new district occur landslide accident, cause more people's injures and deaths, direct economic loss reaches
8.81 hundred million yuan, the main reason for current accident occurs：On the one hand be because architecture sediment accumulate it is too high, on the other hand be then because
For the water in architecture sediment is not discharged quickly.
Still it is easy to produce disaster without good processing method, substantial amounts of stack for architecture sediment at present, therefore,
Solution architecture sediment Quick drainage, solidification problem are the keys of architecture sediment recycling.
The content of the invention
The present invention is an approach of architecture sediment recycling, mainly solves the problems, such as the discharging consolidation of architecture sediment, is realized
Architecture sediment is used for the technology of filler.A kind of Geogrid Reinforced Earth Retaining Wall knot based on architecture sediment has been invented on this basis
Structure and its construction method.Dregs is accelerated to consolidate by laying interlayer drainage arrangement on GSZ top, by architecture sediment
Water is collected in drainpipe by interlayer drainage arrangement and discharged, and improves constraint of the reinforcement material to the soil body, solves architecture sediment money
The problem of source.
The present invention relates to a kind of Geogrid Reinforced Earth Retaining Wall structure and its construction method based on architecture sediment, its is main
By architecture sediment filler, GSZ, precast concrete facade panel, vertical drainage pipe, horizontal drain pipe, interlayer drainage arrangement, row
Ditch, reinforced earth bulkhead strip footing, sand-gravel cushion, connector composition.
Preferably, the interlayer drainage arrangement described in it is located at GSZ top 5cm between 15cm, according to the gradient
2% -5% laying, is connected between interlayer drainage arrangement and vertical drainage pipe by connector, connector and vertical drainage pipe it
Between be placed on by sleeve connection, one end of interlayer drainage arrangement in connector, and the ply stacking angle of connector and interlayer draining
Device is consistent, and vertical drainage pipe passes through sleeve connection with horizontal drain pipe.
Preferably, the interlayer drainage arrangement described in it, including geomembrane, drain bar, long fine geotextiles, reinforced mesh, its
It is characterised by, geomembrane parcel reinforced mesh is located at bottom, and drain bar is located at middle part, and top is then long fine geotextiles, with connecting
The interface of device is connect, is closed using pitch, interlayer drainage arrangement is pre-buried by reinforced mesh and precast concrete facade panel
Part is welded and fixed.
In order to improve constraint of the reinforcement material to architecture sediment filler, the filler grain on reinforcement material surface is on the one hand controlled
Footpath, it is allowed to be no more than 15mm in the maximum particle diameter within the 5cm of reinforcement material surface；On the other hand then in reinforced earth bulkhead
Place drainage arrangement.
The draining mechanism of the present invention is summarized as follows：
Architecture sediment filler cannot be used for the main reason for reinforced earth filler：Due to containing substantial amounts of viscosity in architecture sediment
Soil, cause discharging consolidation difficult, influence whether the interface friction performance between reinforcement material and architecture sediment filler.In order to solve
The technical problem, the present invention place interlayer drainage arrangement, vertical drainage pipe, horizontal drain pipe in reinforced earth bulkhead.Interlayer is arranged
Water installations are made up of geomembrane, drain bar, long fine geotextiles, reinforced mesh, wherein growing fine geotextiles is located at top layer, are mainly
The loss of the filler particles in drainage procedure is prevented, geomembrane parcel reinforced mesh be located at bottom, primarily to reduction layer
Between drainage arrangement deformation quantity in compacting process, the water in dregs filler is smoothly discharged, accelerate the consolidation of filler.Interlayer
Drainage arrangement is placed on GSZ top 5cm between 15cm, is laid according to the gradient 2% -5%, and utilizes connector
Interlayer drainage arrangement and vertical drainage pipe are connected as an entirety, the water that interlayer drainage arrangement is collected is passed through into connector stream
Enter in vertical drainage pipe, then gutter is flowed into by horizontal drain pipe, so as to realize the discharging consolidation process of architecture sediment filler.
