Abstract
The invention discloses a dam front drainage method for sub-dam building in red mud stacking area. The method includes the following steps: a composite soil engineering drainage network is arranged on an inner slope surface of a sub-dam; a gravel drainage layer is arranged on a dam toe of an inner slope; the bottom base of the gravel drainage layer is reinforced through soil and stone materials; area internal drainage pipes are arranged on the inner bottom of the gravel drainage layer; red mud seepage water in the front of a dam enters the area internal drainage pipes via the composite soil engineering drainage network and the gravel drainage layer; the seepage water flows to a drainage ditch on a dam toe of an outer slope of the sub-dam through the area internal drainage pipes, the seepage water flows to stacking area drainage pipes through the drainage ditch, and the seepage water is finally drained to a downstream return pipe along an outer slope surface of a primary dam through the stacking area drainage pipes. According to the method, the red mud seepage water in a front zone of the sub-dam can be drained out as soon as possible, the drying speed of red mud in the front zone of the dam can be increased, and the safety of the dam can be ensured.

Deng, red mud to the pollution of environment based on alkali pollution。
When red mud can't utilize in a large number and must store up, red mud dump need to be built and make red mud concentrate stacking。Red mud generally has wet method to store up, semidry method is stored up, dry method stores up three kinds of techniques in process both at home and abroad。Blowing before stockyard periphery or dam is generally adopted, owing to tapping point and blowing amount are uneven, it is easy to causing hydrops before dam, before dam, the red mud drying time is long, is unfavorable for safety of dam body, it is also difficult to ensure the requirement of dry beach, stockyard length when red mud wet method is stored up, semidry method is stored up。
Summary of the invention
It is an object of the invention to, it is provided that a kind of method that when red mud dump constructs sub-dam, front row, dam is oozed, can discharge smoothly by hydrops before dam, shorten the red mud drying time, extend dry beach, stockyard length, to guarantee safety of dam body。
Technical scheme:
A kind of method that when red mud dump constructs sub-dam, front row, dam is oozed, the method is to construct Zi Ba at the initial dam top stacking red mud, and bottom sub-dam, wide top is narrow, and before constructing sub-dam, the row first carried out bottom sub-dam is oozed, and row oozes construction according to the following steps:
Step one, before sub-dam is constructed in dam crest portion in the early stage, first some building stones of throwing in the red mud of position at the bottom of domatic dam, Zi Ba upstream, then with vibrating roller by building stones compaction by rolling to >=0.93, arrange the basis bottom infiltration layer as sandstone；
Step 2, in one layer of upper berth, basis geotextiles, in geotextiles, then put soakaway trench, soakaway trench arrival end one layer of geotextiles of parcel, the soakaway trench port of export is connected with the gutter of initial dam end face, and soakaway trench is placed with a soakaway trench along sub-dam length direction at interval of 30-50 rice；
Step 3, lays sandstone row's infiltration layer on soakaway trench, is pressed on the limit of composite earthwork drainage network bottom sandstone row's infiltration layer when laying sandstone row's infiltration layer, arranges infiltration layer top at sandstone and repave one layer of geotextiles；
Step 4, construct Zi Ba between the geotextiles at dam and sandstone row infiltration layer top in the early stage, when group height of dam degree reaches 90%, composite earthwork drainage network is layered on Zi Ba upstream domatic, another limit of composite earthwork drainage network is embedded in sub-dam, then sub-dam is filled to design height；
Step 5, digs a gutter at sub-Ba Bajiaochu along dam body length direction, and bottom of trench is provided with drain pipe, and drain pipe backwater ditch with initial dam base of dam domatic along initial dam downstream is connected。
In preceding method, described basis, slightly above initial dam end face, makes the soakaway trench being laid between basis and initial dam end face low inside and high outside to guarantee that in storehouse, infiltration can be discharged in time。
In preceding method, described soakaway trench is positioned at the tube wall of field part and is provided with water seepage hole, and soakaway trench is wrapped with geotextiles。
Compared with prior art, the backwater ditch that the hydrops in red mud dump is drained into initial dam base of dam by soakaway trench by the present invention makes the red mud infiltration of Zi Ba dam forefoot area to discharge as early as possible, and then accelerates the rate of drying of dam forefoot area red mud, is conducive to safety of dam body。
