Description
Technical field
The invention belongs to hydro-structure technical field, and in particular to a kind of rock for exempting from toe board structure.
Background technology
The main body of rock-fill dams is to use gravel embankment, is equipped with the dam that impervious body is built up.It is one kind of earth and rockfill dam.This dam
Advantage is can to make full use of local natural material, adapts to different geological conditions, and construction method is easier, and anti-seismic performance is good
Deng.Its deficiency is that construction diversion and flood releasing structure need to be typically set outside dam, and existing face dam needs toe board as panel
Supporting mass, toe board in order to meet the anti-requirement for blending intensity, it is necessary to be arranged on the enough basement rock of intensity, therefore embedding depth is larger,
Cause slope excavating amount larger, and bring substantial amounts of support engineering amount therewith.The excavation of toe board inner slope, which also increases, simultaneously fills out
The amount of building.Although part excavated material can above dam utilize, but still there is a large amount of abandon to be stacked, it is necessary to transport to slag field.
The content of the invention
The invention aims to solve Face Rockfill Dam excavation in the prior art to cause excavation supporting quantities
It is larger and the problem of thus caused slag field is larger, and a kind of rock for exempting from toe board structure proposed.
To achieve these goals, present invention employs following technical scheme：
It is a kind of to exempt from the rock of toe board structure, including the support plate assigned into water, the side of the supporting plate set
There is the outer slope of panel enrockment substrate, the outer slope of the panel enrockment substrate is provided with panel enrockment toe board close to the side of support plate, described
Panel enrockment toe board is provided with panel enrockment substrate close to the side of support plate, is provided between the panel enrockment substrate and support plate
Panel, the panel include shock resistance panel layer and course of sandbags, and side of the support plate away from panel is provided with panel rockfill,
The panel rockfill includes rockfill area under concrete stack layers, upstream rockfill area, gravel laydown area and downstream water, the concrete
Stack layers are located at top side, and the upstream rockfill area is located at the downside of concrete stack layers, and the gravel stacks area and is located at upstream enrockment
Under area and downstream water between rockfill area, the upper end of the support plate, which is inserted with, fills tunnel closure pipe, and fills tunnel closure pipe
One end connects with the inside of panel enrockment substrate, and the upper end for filling tunnel closure pipe is inserted with filling closure pipe.
Preferably, space is left between panel enrockment substrate and panel the enrockment toe board, and gap is filled with flower hilllock
Rock metalling.
Preferably, the course of sandbags is placed on support plate, shock resistance panel layer and panel enrockment substrate in a stacked fashion
Between.
Preferably, the outside of rockfill area includes under the concrete stack layers, upstream rockfill area, gravel laydown area and downstream water
There is impermeable steel wire.
Preferably, weld together between the filling tunnel closure pipe and filling closure pipe.
Preferably, one end of the filling tunnel closure pipe in panel enrockment substrate, which is provided with, fills tunnel as mouth.
In the present invention, because panel is attached on bedding material, not power transmission substantially is to toe board, as long as therefore connecting knot with panel
Structure keeps homeostasis.When side slope is compared with time slack, grout curtain is carried out at the top of side slope at former toe board position, when side slope is steeper
When, move towards location arrangements grouting tunnel along former toe board and carry out grout curtain, blocked behind the tunnel inducer that is in the milk.In slope table
After coating and completely decomposed layer etc. are disposed in face, grooving pours one piece of soleplate, and sealing is buried in the inside, reserved and slab joint,
Form periphery fissure.Due to substantially avoided the excavation of toe board side slope, reduce excavation supporting amount, while reduce enrockment and fill
Amount, decreases panel quantities.Soleplate, which is poured after completion reaches some strength, to be needed to carry out consolidation grouting.Due to soleplate
Follow contours pour, stronger than toe board structure for terrain adaptability, and remaining structure is identical with conventional panels rock-fill dams, present invention knot
Structure is simple, compared with existing rock, have excavation supporting quantities is small, reduce the enrockment amount of filling and panel quantities,
Terrain adaptability is relatively strong, can reduce the advantages of slag field scale.

Reference picture 1-2, support plate 11 that is a kind of to exempt from the rock of toe board structure, including assigning into water, supporting plate
11 side is provided with the outer slope 5 of panel enrockment substrate, and the outer slope 5 of panel enrockment substrate is provided with panel enrockment close to the side of support plate 11
Toe board 3, panel enrockment toe board 3 are provided with panel enrockment substrate 4, panel enrockment substrate 4 and support plate close to the side of support plate 11
Panel is provided between 11, panel includes shock resistance panel layer 2 and course of sandbags 7, and side of the support plate 11 away from panel is provided with panel
Rockfill, panel rockfill include rockfill area 10 under concrete stack layers 8, upstream rockfill area 9, gravel laydown area 1 and downstream water, mixed
Solidifying mound layer 8 is located at top side, and upstream rockfill area 9 is located at the downside of concrete stack layers 8, and gravel laydown area 1 is located at upstream enrockment
Under area 9 and downstream water between rockfill area 10, the upper end of support plate 11, which is inserted with, fills tunnel closure pipe 13, and fills tunnel closure pipe
13 one end connects with the inside of panel enrockment substrate 4, and the upper end for filling tunnel closure pipe 13 is inserted with filling closure pipe 12, panel
Space is left between enrockment substrate 4 and panel enrockment toe board 3, and gap is filled with granite stones layer, course of sandbags 7 is with stacking
Mode be placed between support plate 11, shock resistance panel layer 2 and panel enrockment substrate 4, concrete stack layers 8, upstream rockfill area
9th, the outside of rockfill area 10 includes impermeable steel wire under gravel laydown area 1 and downstream water, fills tunnel closure pipe 13 and filling
Closure pipe 12 between weld together, in panel enrockment substrate 4 fill tunnel closure pipe 13 one end be provided with fill tunnel as
Mouth 6.
In the present invention, because panel is attached on bedding material, not power transmission substantially is to toe board, as long as therefore connecting knot with panel
Structure keeps homeostasis.When side slope is compared with time slack, grout curtain is carried out at the top of side slope at former toe board position, when side slope is steeper
When, move towards location arrangements grouting tunnel along former toe board and carry out grout curtain, blocked behind the tunnel inducer that is in the milk.In slope table
After coating and completely decomposed layer etc. are disposed in face, grooving pours one piece of soleplate, and sealing is buried in the inside, reserved and slab joint,
Form periphery fissure.Due to substantially avoided the excavation of toe board side slope, reduce excavation supporting amount, while reduce enrockment and fill
Amount, decreases panel quantities.Soleplate, which is poured after completion reaches some strength, to be needed to carry out consolidation grouting.Due to soleplate
Follow contours pour, stronger than toe board structure for terrain adaptability.
Certainly, the above is the concrete application example of the present invention, and the present invention also has other embodiments, all using equivalent
The technical scheme that replacement or equivalent transformation are formed, all falls within protection domain of the presently claimed invention.
