Description
Technical field
The invention belongs to slope project fields, specifically, being related to a kind of side slope surface seepage prevention design method.
Background technique
Field is utilized in underground engineering, can often encounter the top plate of the underground engineerings such as stope/tunnel/chamber even water conservancy and hydropower
Control problem, one of them is exactly the thickness for needing to accurately determine roof strata, is the disposition and roof control of subsequent top plate
Foundation is provided.
The measurement research of coal seam thickness, the physics in coal seam are concentrated mainly on about the research of roof strata thickness measurement at present
Chemical property is totally different from the rock stratum of other lithology rock mass, it is impossible to be used in the measurement of other underground engineering top plate thicknesses.In addition,
In underground engineering support work, it is sometimes desirable to the loosening belt range of Underground engineering roof strata country rock, it is deep as anchoring
Degree or the scientific basis of other support engineering measures.Such as it in the underground water-seal oil depot digging process of East China, needs to detect
The Relaxation Zone range size of cavern's roof strata country rock, provides technical basis for method for protecting support.
It is special due to ore body immediate roof bauxite and clay rock especially in the aluminous mine recovery process of underground
Property, it solves and control stope ore body immediate roof soft rock rock stratum is the shared technical problem of aluminous mine exploitation.For stope top
Plate security control and management provide foundation, are exactly at present to seek a kind of ore body one of the problem of aluminous mine most urgent urgent need to resolve
The ways and means of immediate roof thickness quick detection.
In view of this present invention is specifically proposed.
Summary of the invention
The technical problem to be solved in the present invention is that overcoming the deficiencies of the prior art and provide a kind of side slope surface seepage prevention design

The bare rock at angle occurs, and excavation and anchorage ditch simultaneously；
Step 2, backfill is carried out at the bottom of slope of each platform, accomplishes inclined-plane, and carry out hand compaction, to increase side slope
Stability；
Step 3, gutter excavation is carried out in next adjacent platforms；
Step 4, it is first laid with one layer of geotextiles on side slope surface, prevents geomembrane from being scratched by the rock in slope surface, plays
Protective effect to geomembrane, adjacent two width geotextiles are connected by binding hole using Binding material；
Step 5, it then in the geotextiles laid is laid with geomembrane, geotextiles and geomembrane top will pass through anchoring groove
And be compacted with backfill, and to reserve certain length, and the lower part of geotextiles and geomembrane will be taped against always next phase
Until the gutter position of adjacent platform；
It step 6, is the convenience of constructing operation, the junction between adjacent two width geomembrane is geotechnological using the connection of one fixed width
Film is flexibly connected；
Step 7, the geomembrane in slope surface is fixed, prevents the geomembrane in slope surface from slipping off along slope surface, keeps away simultaneously
The geomembrane exempted from slope surface is wiped off by strong wind；
Step 8, in the gutter excavated, geotextiles are first laid with, re-lay geomembrane, and to the geotechnique in gutter
Cloth and geomembrane are fixed.
Further, in the step 1, side slope surface either opencut side slope, be also possible to roadside
Side slope can also be other natures or Artificial Side-slope etc., and the present invention does not refer in particular to a certain type side slope specifically, as long as having
The slope surface of certain slope requires all in present invention protection right.
Further, in the step 3, the section configuration in gutter can be the arc-shaped of rule, rectangle, trapezoidal etc.,
It can also be other irregular section configurations, discharge section shape of the present invention does not refer in particular to a certain shape specifically, as long as setting
