Face misalignment is monitored.
To achieve the goals above, the technical solution that the invention uses for：A kind of tailing dam surface displacement monitoring point
Method for arranging, which is characterized in that its step is：Monitoring point is divided into：Surface displacement monitoring point and displacement monitoring basic point；
1), surface displacement monitoring point distributing position is：3-4 is set and arranges surface displacement monitoring point, often arranges surface displacement monitoring
Point is arranged on same straight line；
1a), first row and end row's surface displacement monitoring point are arranged in initial dam dam crest and fill dam dam crest；
1b), the setting position of the intermediate row surface displacement monitoring point between first row and end row is according to the stabilization of flood operating mode
The slip circle front and rear edges location determination of calculating；
2), displacement monitoring basic point distributing position is：Displacement monitoring basic point is arranged in the solid and reliable position of both sides massif, point
Position no less than 3.
The surface displacement monitoring point buried depth is 0.6m.
The displacement monitoring basic point buried depth is 1.6m.
Surface displacement monitoring point in the method for arranging of tailing dam surface displacement monitoring point, which is characterized in that its structure is：Packet
External brick enclosure wall is included, rectangular cross section is equipped at brick enclosure wall bosom position and observes pier, is observed in rectangular cross section
Clay is backfilled between pier and brick enclosure wall；The round steel of the pre-buried φ 20mm of rectangular cross section observation socle；Described is brick
It is stamped cover board in enclosure wall top surface.
The round steel exposes rectangular cross section observation pier 30mm.
The rectangular cross section observation pier makes raw material and slag or volcano grey matter cement, rank is used to be more than or equal to 32.5
Grade；Stone uses grain size for the middle sand of 0.15-3mm using the natural pebble or hard rubble, sand of grading qualification, clay content
Less than or equal to 3%；Sulphates content is less than or equal to 1% in mixing water.
The invention has the beneficial effect that：
1, the intermediate row position of monitoring point is determined according to the flood stable conditions result of calculation of maximum height of dam section, is compensated for
The conventional method of intermediate row position is determined by experience array pitch, and there is scientific theory foundation.
2, observation pier, which makes, preferentially uses slag or volcano grey matter cement, it is therefore prevented that freeze thawing influences, and compensates for using fine coal
The deficiency of ash concrete.
3, the monitoring point for displacement architecture basics are firm, cheap, easy for construction, through live operation test, may be implemented
Accurate safety monitoring and displacement early warning.
