Description
Technical field
The invention belongs to reinforced earth technology field, in particular to a kind of Geogrid Reinforced Earth Retaining Wall based on architecture sediment
Structure and its construction method.
Background technique
Currently, with the acceleration of urbanization process, construction industry is also fast-developing simultaneously, the construction of road, foundation pit excavation,
The quantity for the architecture sediment that the construction etc. of subway generates every year is especially huge.Due to containing more cohesive soil in architecture sediment,
It will lead to discharging consolidation difficulty, so it can neither be used for recycled aggregate, regeneration filler can not be used for.The processing of dregs at present
Mode is essentially filled and is stacked, to can cause great harm to environment and will increase subsequent processing cost.2015
Landslide accident occurs for the red col dregs receiving field in December, Shenzhen light new district, causes more people's injures and deaths, direct economic loss reaches
8.81 hundred million yuan, the main reason for current accident occurs: being on the one hand because architecture sediment accumulate it is excessively high, be on the other hand then because
For the water in architecture sediment is not discharged quickly.
At present for architecture sediment still without good processing method, a large amount of stack is easy to generate disaster, therefore,
Solve architecture sediment Quick drainage, solidification problem is the key that architecture sediment recycling.
Summary 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.Accelerate dregs consolidation by being laid with interlayer drainage arrangement on TGXG top, it will be in architecture sediment
Water is collected in drainpipe by interlayer drainage arrangement and is discharged, and constraint of the reinforcement material to the soil body is improved, and 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, it is main
By architecture sediment filler, TGXG, 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, including geomembrane, drain bar, long fine geotextiles, reinforced mesh,
Be characterized in that, geomembrane package reinforced mesh is located at bottom, and drain bar is located at middle part, and top is then long fibre geotextiles, with company
The interface for connecing device, is closed using pitch, and interlayer drainage arrangement is pre-buried by reinforced mesh and precast concrete facade panel
Part is welded and fixed.
Preferably, the interlayer drainage arrangement described in is located at TGXG top 5cm between 15cm, according to the gradient
2% -5% is laid with, and is connected between interlayer drainage arrangement and vertical drainage pipe by connector, connector and vertical drainage pipe it
Between by sleeve connection, one end of interlayer drainage arrangement is placed in connector, and the ply stacking angle of connector and interlayer drain
Device is consistent, and vertical drainage pipe and horizontal drain pipe pass through sleeve connection.
Draining mechanism of the invention is summarized as follows:
Architecture sediment filler cannot be used for the main reason for reinforced earth filler: due to containing a large amount of viscosity in architecture sediment
Soil causes discharging consolidation difficult, influences 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 row
Water installations are made of geomembrane, drain bar, long fine geotextiles, reinforced mesh, wherein long fibre geotextiles are located at top layer, are mainly
The loss of the filler particles in drainage procedure is prevented, geomembrane package reinforced mesh is located at bottom, primarily to reduction layer
Between drainage arrangement deformation quantity in compacting process, the water energy in dregs filler is smoothly discharged enough, accelerates the consolidation of filler.Interlayer
Drainage arrangement is placed on TGXG top 5cm between 15cm, is laid with 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 passes through connector stream
Enter in vertical drainage pipe, then gutter is flowed by horizontal drain pipe, to realize the discharging consolidation process of architecture sediment filler.
