Wastewater from red mud is in alkalescence, and the antiseepage for stockyard requires higher, and antiseepage film generally uses infiltration coefficient≤10-12cm/s, and heap
Field forms overall antiseepage, it is impossible to has attached liquid seepage, causes some serious environmental pollutions and health hazard problem.
At present, domestic southern alumina producer gradually increases, and the red mud dump overwhelming majority is gully type stockyard, its both sides mountain
Body side slope is generally rock foundation.Traditional anchorage style is anchoring groove, it is necessary first to flat with the mechanically formed anchoring with operating surface
Platform, the cross dimensions minimum of next anchoring groove needs 0.8m*0.8m, and the berm width that traditional anchorage style needs is not less than 4m,
Long in time limit and excavation and anchorage ditch difficulty is big on batholith face, investment is high.Impervious barrier at least needs three in rock bolting ditch simultaneously
Place's bending, basement rock anchoring groove corner is very difficult to be processed into the turning of smooth smooth-going, wedge angle etc. easily occurs, so easily draw
The destruction of impervious barrier is played, seepage is formed, causes environmental pollution, or even health hazard.
Utility model content
The technical problems to be solved in the utility model is that there is provided a kind of anchoring knot of red mud dump batholith slope seepage control layer
Structure, can reduce rock slope and be opened flat digging quantities, it is to avoid carry out the big anchoring groove of task difficulty in rock slope and excavate, with
Overcome that prior art is present quantities is big, task difficulty big, investment is high and easily causes antiseepage damage layer, cause environment dirt
Dye, or even the deficiency such as health hazard.
The technical solution of the utility model is such：
A kind of anchor structure of red mud dump batholith slope seepage control layer, including the anchored platform base that place Slope leveling goes out
Face, the anchored platform basal plane corner is circular arc corner；Anchored platform basal plane is provided with whitewashing, and the surface of whitewashing, which is provided with, to be used to lay
The anchored platform surface of impervious barrier, lays impervious barrier on anchored platform surface, and impervious barrier uses band steel with holes and expansion
Bolt is anchored in the borehole；Band steel and appearing for expansion bolt are wrapped provided with concrete above band steel and expansion bolt
Wrap up in.
Wherein, anchored platform base width is not less than 3m.The arc radius of circular arc corner is 0.3m.Drilling is flat along anchoring
Platform surface 2~3m of interval sets one.Band steel model specification with holes is 8*100mm, and length is 1.0m；Expansion bolt specification is
M16*185mm.Concrete material is C15 or C20, and physical dimension is 1.6m*0.6m*0.2m.
The construction method of this red mud dump batholith slope seepage control layer anchor structure is constructed according to the following steps：
Firstth, anchored platform of being cleared in rock slope basal plane；
Secondth, the corner of anchored platform basal plane sets circular arc corner；
3rd, it is levelling using whitewashing in anchored platform basal plane, form the anchored platform surface for meeting laying impervious barrier；
4th, drilled on anchored platform basal plane；
5th, impervious barrier is laid on anchored platform surface, and impervious barrier, size and bore size are cut in the position of drilling
Unanimously；
6th, band steel with holes is placed on impervious barrier；
7th, after band steel is placed, fixed in time using expansion bolt；
8th, band steel and expansion bolt are appeared using concrete and wrapped up, form complete and firm impervious barrier anchor
Gu.
Levelling gunite material is M7.5 cement mortar in third step.
The anchor structure of red mud dump batholith slope seepage control layer of the present utility model, is usually to form certain elevation in stockyard
Anchored platform basal plane, the levelling basal plane formation of whitewashing meet the platform surface of laying impervious barrier；In the drilling of embedded expansion bolt position；
Lay impervious barrier；Impervious barrier is cut in bore position；Place band steel；Construction expansion bolt, is poured on band steel and expansion bolt
Concrete is built, effective, firm impervious barrier anchorage style is formed.
The structure is used for the impervious barrier anchor situation of red mud dump rock slope.Storage yard slope interval 10~20m elevations are set
Anchored platform is put, the anchorage style for setting band steel and expansion bolt to be combined on platform.
The utility model can effectively complete anchoring of the impervious barrier in rock slope, can reduce rock slope and be opened flat
Dig quantities, it is to avoid carry out the big anchoring groove of task difficulty in rock slope and excavate, reduce antiseepage damage layer and cause environment and
Healthy probability.Connected mode of the present utility model, it is both easy to operate and economical and practical.
