Description
Technical field
The present invention relates to a kind of method of embankment processing, especially a kind of method of ecological type immerseable embankment processing.
Background technology
Immerseable embankment refers to that road foundation is on the verge of river and lake, and roadbed is to meet flood control level to carry out high roadbed design.Design
When immerseable embankment, saturated yielding shadow caused by infiltration, fluctuation in stage, wave invasion, current scour and underground water Yong Sheng should be fully considered
It rings.
It is directed to the saturation roadbed antiseepage of reservoir location, presently, there are several administration ways：1）Antiseepage film process；2）Reinforcing bar is mixed
Solidifying soil panel surface processing；3）Grout curtain.But the 1st）With 2）The processing mode of kind is only applicable to surface layer antiseepage, is easy to brokenly
Bad, antiseepage film service life is relatively low；And the 3rd）Kind processing mode is only applicable to cut subgrade antiseepage, and construction is complicated, material utilization amount
Greatly.And how ensureing that impervious body is located at the side that borders on the river and is neither easy to destroy, service life is long, and can meet embankment construction party
Just, it economizes on resources, and it is a urgent problem that can also reduce settlement of subgrade.
Invention content
The object of the present invention is to provide a kind of methods of ecological type immerseable embankment processing.The present invention has impervious body not
Destructible, service life is long, easy for construction, economizes on resources, the few feature of settlement of subgrade.
Technical scheme of the present invention：A kind of method of ecological type immerseable embankment processing, includes the following steps：
1）In embankment bottom casting concrete pedestal；
2）Open up several consolidation grouting holes and grout curtain hole downwards across concrete pedestal, and respectively to consolidation grouting hole and curtain
Grouting in curtain grout hole；
3）Step 2）After grouting solidification, straight wall cavity is installed in the top of concrete pedestal, and original state is backfilled in straight wall cavity
Native stone one；
4）In straight wall cavity, multilayer TGXG is arranged in side and top near water, is tamped with earthen backfill between adjacent TGXG；
In straight wall cavity backwater side backfill stone；
5）In TGXG, side backfills undisturbed soil stone two near water, geotechnical grid is arranged above undisturbed soil stone two, in geotechnological lattice
Planting plants after soil are ploughed in indoor backfill.
The method of ecological type immerseable embankment processing above-mentioned, step 2）In, the setting spacing in the consolidation grouting hole is 1-
3m。
The method of ecological type immerseable embankment processing above-mentioned, step 2）In, the setting spacing in the grout curtain hole is
0.5-1.5m。
The method of ecological type immerseable embankment processing above-mentioned, step 3）In, the straight wall cavity is assembled straight wall cavity,
It is assembled by concrete slab.
The method of ecological type immerseable embankment processing above-mentioned, step 4）In, the spacing between the adjacent TGXG is
1.5-2.5m。
The method of ecological type immerseable embankment processing above-mentioned, step 4）In, the straight wall cavity backwater side first backfills stone
Block forms rockfill area, and then backfill stone forms native stone back filled region.
The method of ecological type immerseable embankment processing above-mentioned, step 5）In, the inside of the geotechnical grid is equipped with lacing wire.
Beneficial effects of the present invention
The present invention forms compound by using the tensile property of the anti-permeability performance and TGXG of straight wall cavity and seepage proof curtain
System reduces unilateral lake body water pressure to the adverse effect of embankment, makes impervious body using the ecological preferable principle of geotechnical grid
It is survivable, extend the service life of impervious body；Meanwhile avoiding the differential settlement of high-fill roadbed.In addition, in not shadow
Under the conditions of ringing construction speed, the original state earth rock material for making full use of periphery to excavate saves engineering material investment, improves material profit
With rate, the waste of resource is reduced, the spirit for meeting national energy conservation and emission reduction requires.

Specific implementation mode
With reference to embodiment, the present invention is further illustrated, but is not intended as the foundation limited the present invention.
The embodiment of the present invention
A kind of method of ecological type immerseable embankment processing, steps are as follows：
1）Casting concrete pedestal 10, base thickness 50cm ~ 100cm in embankment bottom；
2）Several consolidation grouting holes 1 and grout curtain hole 2 are opened up downwards across concrete pedestal 10, and respectively to consolidation grouting hole
1 and grout curtain hole 2 in grouting；
3）After step 2 grouting solidification, the installation straight wall cavity 3 in the top of concrete pedestal 10, and backfill is former in straight wall cavity 3
Shape soil stone 1；
4）In straight wall cavity 3, multilayer TGXG 8 is arranged in side and top near water, is rammed with earthen backfill between adjacent TGXG 8
It is real；In 3 backwater side backfill stone of straight wall cavity；
