Abstract
A kind of pre-buried row oozes reinforcement synergy material stacking tailing dam novel construction method, and its step is as follows: according to the granule composition of mine tailing, (1) determines that pre-buried row oozes the laying vertical interval of reinforcement synergy material；(2) pre-buried row oozes the based process of reinforcement synergy material；(3) lay row and ooze reinforcement synergy material；(4) ooze reinforcement synergy material higher slice the row paved and pile up mine tailing, repeat (2)～(3) step, complete pre-buried row and ooze the construction of reinforcement synergy material.Advantage is: the row both with reduction dam seepage line oozes function, possesses again the reinforcement function improving dam body intensity enhancing dam stability；Construction method and technique are simple；Duration is short, and construction costs is less, low cost, cost saving；Row is oozed the intensity of reinforcing body and can be adjusted selecting according to dam stabilization sexual needs；The optional heap dam side slope steeper than conventional method, is effectively increased storage capacity.
Description
Technical field
The present invention relates to tailing dam Geotechnical Engineering field, a kind of row for pre-plugged in normal storehouse dry method accumulation tailing dam work progress oozes reinforcement synergy material stacking tailing dam novel construction method.
Background technology
Properly functioning tailing dam is not reinforced, during dry method is piled up and increased, a small amount of method using pre-buried reinforcement material improves dam body intensity, do not consider that horizontal row blends reinforcement and jointly acts on, but use row to ooze or reinforcement method consolidation process after dam heightening.During conventional dry accumulation of dam, dam stabilization safety coefficient is low, and accumulation of dam height is less, and the later stage processes complicated construction technique, and difficulty of construction is big, and construction costs is high.
Summary of the invention
It is an object of the invention to develop a kind of Against Sliding Stability ability of strengthening mine tailing body, the row that accelerates mine tailing body oozes ability, and the pre-buried row accelerating mine tailing body consolidation oozes reinforcement synergy material stacking tailing dam novel construction method.
The pre-buried row of the present invention oozes reinforcement synergy material stacking tailing dam novel construction method, and step is as follows:
1. form according to the granule of mine tailing and determine that pre-buried row oozes the laying vertical interval of reinforcement synergy material；General 1～5m, get the small value when granule is thin, take large values when granule is thick；
The most pre-buried row oozes the base treatment of reinforcement synergy material: roll rear smooth fill dam surface by design requirement, it is ensured that the substrate surface flare gradient is 1%～5%；
3. lay row and ooze reinforcement synergy material: ooze reinforcement synergy material and be laid in by being reliably connected integral row and rolled smooth surface of base, each piece of row is oozed reinforcement synergy material and is connected reliably each other, the drainage channel that each piece of row oozes reinforcement synergy material is reliably connected, row extends domatic in bleed-through road, with be arranged at domatic open drain drop-over, it is ensured that draining is unimpeded；Refer to accompanying drawing 1: pre-buried row oozes reinforcement synergy material heap dam engineering method schematic diagram；
4. ooze reinforcement synergy material higher slice the row paved and pile up mine tailing, repeat 2.～3. step, complete pre-buried row and ooze the construction of reinforcement synergy material.
The pre-buried row of the present invention oozes the advantage of reinforcement synergy material stacking tailing dam novel construction method: 1. dam body pile up increase after both had reduce dam seepage line row ooze function, possess again improve dam body intensity enhancing dam stability reinforcement function；2. construction method and technique are simple；3. the duration is short, and construction costs is less, low cost, cost saving；4. row ooze reinforcing body intensity can according to dam stabilization sexual needs be adjusted select；5. the optional heap dam side slope steeper than conventional method, is effectively increased storage capacity；6. can increase dam stability, make dam body heap height increase, also can be effectively increased storage capacity；The most less minimizing country and owner's secondary build the storehouse destruction to ecology with environment, and benefit future generations offspring.

Detailed description of the invention
According to Fig. 1, Fig. 2, the embodiment that the pre-buried row of the present invention oozes reinforcement synergy material stacking tailing dam novel construction method is as follows:
1. form according to the granule of mine tailing and determine that pre-buried row oozes the laying vertical interval of reinforcement synergy material；General 1～5m, get the small value when granule is thin, take large values when granule is thick；The row of present embodiment oozes reinforcement synergy material selection drainage geogrid, such as accompanying drawing 2: pre-buried drainage geogrid organigram, the common GSZ of 1--in figure, 2 common plastics draining boards or reinforcement draining board, 3 tailing dams are domatic, 4-mine tailing accumulation body, 5--gutter；
The base treatment of the most pre-buried drainage geogrid: smooth mine tailing accumulation body 4 surface after rolling by design requirement, it is ensured that the mine tailing accumulation body 4 surface flare gradient is 1%～5%；
3. drainage geogrid is laid: be laid in rolled smooth mine tailing accumulation body 4 surface by being reliably connected integral drainage geogrid, use plastics binding strap colligation firm between each piece of drainage geogrid, draining board drainage channel extends domatic, enter in the gutter 5 being arranged on tailing dam domatic 3, the draining board of each piece of drainage geogrid should be reliably connected, it is ensured that drainage channel is unobstructed；
The drainage geogrid paved is piled up mine tailing, repeats 2.～3. step, complete the construction of whole pre-buried drainage geogrid.
