Description
Technical field
The present invention relates to a kind of Earthworking reinforced bar materials, belong to the draining and field of reinforcement of roadbed and barricade.
Technical background
In Reinforced Material with Clay Engineering when using cohesive soil as filler, after surface water or Groundwater infiltration filler, viscosity
Water in soil can not be discharged in time, this can reduce the effect of contraction of cohesive soil and reinforcement material, lead to reinforcing body reduced performance, into
And reduce the stability of earth structure.Therefore, performance of the cohesive soil as the earth structure of filler is improved, it is necessary to adopt
With good draining and reinforcement facility.At present it has been proposed that plastic draining board level to be laid in roadbed to the row for improving roadbed
Water effect, but there is following two in such way.First, plastic draining board is easy to be pressed during compacted subgrade
It is bad, and then influence its drainage effect；Second, plastic draining board cannot play reinforced action.Therefore, for using cohesive soil to fill
Roadbed and barrier wall structure, if can be even more ideal using if a kind of Earthworking reinforced bar material for having both reinforcement and drain function
, the bearing capacity and stability of roadbed and barrier wall structure on the one hand can be improved, the draining of cohesive soil on the other hand can be accelerated solid
Knot.
Summary of the invention
In view of the above shortcomings of the prior art, technical problem to be solved by the invention is to provide one kind to have draining
The TGXG of function not only has the function of excellent reinforcement but also has efficient drainage performance, can be applied to cohesive soil and fill out
The roadbed and barricade engineering built.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the invention is that: with drain function TGXG
It is made of grid cross rib, grid longitudinal rib and longitudinal drainage band；Grid cross rib is inserted perpendicularly into hole of the longitudinal drainage with side, and
It is bonded in intersection melting welding；Grid longitudinal rib and grid cross rib weld at square crossing；
Longitudinal water band is by lower layer's reinforced bar net, drainage belt ribs, suction water cellulose, upper layer reinforced bar net, geotextiles
Filter membrane and water suction cotton pad composition；Upper layer reinforced bar net and lower layer's reinforced bar net are bonded in upper surface and the following table of drainage belt ribs respectively
Face, and in the support plate fixing groove of the vertical supporting plate insertion upper layer reinforced bar net of lower layer's reinforced bar net, suction water cellulose longitudinal direction cloth
It sets between upper layer reinforced bar net and lower layer's reinforced bar net, geotextiles filter membrane is covered on the appearance of upper layer reinforced bar net and lower layer's reinforced bar net
Face, water suction cotton pad is placed on longitudinal drainage band both ends, and is in contact with discharging water fiber end.
The grid cross rib and longitudinal rib are Soil test.
The upper layer reinforced bar net and lower layer's reinforced bar net cross section is designed as arc, the aperture of arch section surface, mesh ruler
Very little is (3~6) mm × (3~6) mm, wherein has vertical supporting plate on the inside of lower layer's reinforced bar net arch section, height is according to locating for
The height of position drainage belt determines, there is support plate fixing groove on the inside of upper layer reinforced bar net arch section, and groove size is according to erecting
It is determined to the size of support plate, ginseng is as shown in figure 3 and figure 4.
The drainage belt ribs side hole, end one end are that the fastener other end of buckle structure is then embedding
Firmware, it is shown in Figure 2.
The present invention has following technological merit:
1. the present invention is made of grid cross rib, grid longitudinal rib and longitudinal drainage band, wherein grid cross rib and longitudinal rib are soil
Work band not only has the function of excellent reinforcement, but also has efficient drainage performance.
2. being disposed with suction water cellulose inside longitudinal drainage band, wherein suction water cellulose is made of hydrophilic hygroscopic materials,
With a large amount of fine drainage channels, water is sucked out from soil for elder generation, and then the water of suction is discharged along its internal drainage channel
The soil body, therefore improve the discharging water efficiency of longitudinal drainage band.
3. longitudinal drainage band is fabricated to flat, its contact area with soil is increased, longitudinal drainage band is conducive to
Draining.
4. being evenly arranged with vertical supporting plate inside longitudinal drainage band, it is enough anti-not only to ensure that longitudinal drainage band has
Pressure energy power will not be subject to crushing during compacted subgrade, it is thus also avoided that its internal suction water cellulose is crushed, and then influences
Its discharging water effect.
5. being provided with buckle structure and water suction cotton pad at longitudinal drainage band both ends, it can easily connect muti-piece and drain geotechnological lattice
The longitudinal drainage band of grid, forms unobstructed drainage channel, therefore facilitate site operation, enhances the practical of drainage geogrid
Property.
