Ground width is wide, and removal expense is high；Higher to ground requirement for bearing capacity using retaining structure, engineering cost is big.
Summary of the invention
The purpose of the utility model is to provide a kind of no toe board buttress type road shoulder retaining wall structures, and can be used as distance is restricted
Under the conditions of gear shield, effectively reduce occupied area.
The technology employed by the present utility model is
A kind of no toe board buttress type road shoulder retaining wall structure, it is characterised in that:
Horizontal wall heel slab is set under the ground line of road shoulder slope surface, longitudinal vertical metope is set up on the outside of wall heel slab
Plate；
Above wall heel slab, laterally vertical counterfort is set on the inside of shingle nail；
Filled with infiltration filler on the inside of shingle nail.
Infiltration filler successively fills to form multilayered structure, and infiltration filler top is provided with surface layer of subgrade bed.
Surface layer of subgrade bed top surface sets the weathering tilted down from center to both lateral sides, and the gradient is 2~4%.
The drain hole of many places lateral direction penetrating is set from top to bottom on shingle nail.
The outside gradient of drain hole is 4%.
It is close to shingle nail inner wall and is provided with loaded filter, loaded filter is to seep draining sheet material.
Loaded filter bottom is provided with concrete water barrier.
Setting bellend, bellend top surface are provided with longitudinal vertical guard rail outward at the top of shingle nail.
The setting of counterfort longitudinal direction parallel interval, inner side end are inclined-plane from the outside to the core.
Wall heel slab, shingle nail and counterfort are reinforced concrete structure.
The utility model has the advantage that
It 1, can effectively save soil money without toe board buttress type road shoulder retaining wall structure under the premise of guaranteeing stability of slope
Source can be widely applied in the highway layout of the railway limited by terrain and its features, highway and cities and towns periphery.
2, it can guarantee that roadbed side slope is stablized without toe board buttress type road shoulder retaining wall structure, it is low to ground requirement for bearing capacity.
Roadbed ontology has good stability, and can effectively prevent embankment sliding or unstability.
Detailed description of the invention
Fig. 1 is the utility model structure section figure.
Fig. 2 is the utility model structural perspective.
In figure, 1- wall heel slab, 2- shingle nail, 3- counterfort, 4- infiltration filler, 5- surface layer of subgrade bed, 6-, which seeps, drains sheet material, and 7- is let out
Water hole, 8- concrete water barrier, 9- guard rail.
Specific embodiment
The utility model is described in detail With reference to embodiment.
The utility model relates to a kind of no toe board buttress type road shoulder retaining wall structures, are arranged under the ground line of road shoulder slope surface
Horizontal wall heel slab 1 sets up longitudinal vertical shingle nail 2 on the outside of wall heel slab 1.It is set on the inside of 1 top of wall heel slab, shingle nail 2
Laterally vertical counterfort 3 is set, the longitudinal parallel interval setting of counterfort 3, inner side end is inclined-plane from the outside to the core.Wall heel slab 1, metope
Plate 2 and counterfort 3 are reinforced concrete structure, need preparatory assembling reinforcement, build mould pouring construction.
Filled with infiltration filler 4 on the inside of shingle nail 2, infiltration filler 4 is that fine grained soil content is greater than less than 10%, infiltration coefficient
10-3The coarse-grained soil of cm/s.Infiltration filler 4 successively fills to form multilayered structure, and infiltration 4 top of filler is provided with surface layer of subgrade bed 5, base
Bed surface layer 5 uses graded broken stone filling technology.5 top surface of surface layer of subgrade bed sets the weathering tilted down, the gradient from center to both lateral sides
It is 2~4%.
The drain hole 7 of many places lateral direction penetrating is set from top to bottom on shingle nail 2.The outside gradient of drain hole 7 is 4%.
It is close to 2 inner wall of shingle nail and is provided with loaded filter, loaded filter is to seep draining sheet material 6, and it is molten with sleave for seeping draining sheet material 6
Melt geosynthetics made of lapping, compressive resistance is high, aperture density is big, has comprehensive drain function.Loaded filter bottom
Portion is provided with concrete water barrier 8, and the effect of loaded filter is to prevent the fine grained soil in infiltration filler 4 from bringing drain hole by water, makes
It is blocked at drain hole 7.Concrete water barrier 8 can prevent water flow from flowing into retaining wall structure bottom from loaded filter, ensure that water flow
It is flowed out from drain hole 7.
Setting bellend, bellend top surface are provided with longitudinal vertical guard rail 9 outward at shingle nail 2 top.
When construction:
According to no toe board buttress type road shoulder retaining wall structural plan size and the elevation at each position, basis sideline and base are determined
Excavation line is cheated, then excavation pit, after substrate detection is qualified, carries out the reinforcement fabrication of wall heel slab 1, counterfort 3, shingle nail 2.It pours
Wall heel slab 1, the template and installation of production and installation shingle nail 2, counterfort 3, pours retaining walls panel 2 and counterfort 3, carries out simultaneously
Drain hole 7, seep draining sheet material 6, concrete water barrier 8 pre-buried installation and pour.It constructs the filler 4 that seeps water after wall, then fills out again
Build the installation of surface layer of subgrade bed 5 and guard rail 9.
The content of the utility model is not limited to cited by embodiment, and those of ordinary skill in the art are practical new by reading this
Type specification and to any equivalent transformation that technical solutions of the utility model are taken, be the claim institute of the utility model
Cover.
