Gangue library is a cause of danger of man-made mud-rock flow that has high potential energy, existence breaks through dam danger, once crash, cause serious especially big accident easily. Strengthen gangue library to install full inspection and hidden trouble platoon to check deep, eliminate safe hidden danger in time, the safe state of library of gangue of real time control has great sense. We will carry the article safety of area of library of library of inspection of inspection of safety of gangue library prevent or control flood, gangue dam safety, gangue checks 3 respects to tell everybody, what does inspection of gangue library safety check, how to check.
Safety of one prevent or control flood is checkedWhether does the level of prevent or control flood that checks gangue library design accord with this regulations regulation. The prep above of standard of prevent or control flood that should design or when be equal to this regulations to set, the pluvial parameter that can press original design undertakes checking; When the standard of prevent or control flood of the design sets under this regulations, should undertake pluvial computation and tone Hong Yan calculate afresh.
Gangue library water level detects: Its measure an error to should be less than 20mm.
Gangue library beach carries tall Cheng on the head detect: Should edge dam (beach) top direction is decorated measure a dot to undertake actual measurement, its measure an error to should be less than 20mm.
When high one end of beach top one aspect of the matter is low, should be in low level paragraph choose inferior place to detect 1 ~ is nodded 3 times; When beach top on any account is same, should pick inferior point not less than 3 are nodded; Other condition, every 100m dam is long choose inferior place to detect 1 ~ is nodded 2 times, but gross not less than nod 3 times.
The nadir in measuring a place each carries elevation on the head as gangue library beach.
Beach of deposit of examination gangue library does the average gradient of the beach: Should inspect deposit to fight the level off case of the beach, every 100m dam is long decorate not less than 1 ~ 3 section.
Row big build content safety to examine main content: Build content to have without be out of shape, displacement, mar, silt is blocked up, whether does catchment ability satisfy a requirement to wait.
Catchment well examines content: Dimension of the internal diameter of the well, window reachs the place, wall of a well denudes, fall off, the leakage, biggest break begins width, well body gradient and change, place of coupling of well, canal, floater of water inlet surface, method of close over of well of out of service.
Catchment contain canal examines content: Section dimension, be out of shape, damaged, rupture and abrasion, the biggest break begins width, the shut-off of water between the canal reachs filling, the silt inside contain canal is blocked up etc. To cannot be being entered inside inclined chamfer of the little section drainpipe of the examination and catchment can be recorded according to construction and cross Shui Chang to connect a circumstance to decide.
Catchment Sui hole examines content: Section dimension, the cave in inside the hole, line build by laying bricks or stones is out of shape, damaged, rupture, flake and abrasion, the biggest break begins width, adjustable seam, shut-off of water and filling, the silt inside the hole is blocked up reach osculum operating mode to wait.
Big channel checks spillway, cut content: Section dimension, coast of hillside of along the line, cave in, protect build by laying bricks or stones to be out of shape, damaged, rupture and abrasion, the silt inside channel is blocked up etc, still should check overflow bank to carry tall Cheng on the head to spillway, disappear force pool and disappear force bank.
2 gangue dam installs full inspectionGangue dam safety examines content: The outline dimension of dam, be out of shape, interstitial, coast and leakage, dam face protection.
The displacement of gangue dam is monitored can use inspect standard line law and ahead to hand in collect a magic art;
The displacement of gangue dam is monitored annual not less than 4, displacement should increase the number that monitor when unusual change;
The water level of gangue dam is monitored include big water level to monitor with groundwater infiltration line is monitored;
Water level monitors every quarter not less than 1, mix during rainstorm the number that monitor should increase when water level is unusually fluctuant.
Detect of dam outside slope slope compares: Every 100m dam grows not less than 2 point, should choose in most large dams tall section and dam slope are steeper section.
The measurement of horizontal distance and elevation the error is not more than 10mm. Actual slope compares gangue dam steep at design slope is compared, should have stability review a case in which a death sentence has been passed by a lower court, if stability is insufficient, should take step.
Check dam body displacement: The displacement of requirement dam measures change to answer balanced, without choppy phenomenon, and should year after year is reduced. Change occurrence mutation when displacement quantitative change or have when increasing a current, should prove a cause, appropriate processing.
Examination dam body has without vertical, transverse break: When dam body occurrence break, should find out interstitial length, width, deepness, trend, configuration and cause of formation, decide harm degree.
Check dam body coast: When dam body occurrence coast, should find out the dynamic trend of coast position, limits and configuration and coast.
Area of library of 3 gangue library installs full inspectionSafety of area of gangue library library examines main content: Stability of circumjacent hill body, construction of building of violate the rules and regulations, violate the rules and regulations and violate the rules and regulations are collected choose the case such as exercise.
Examine the case such as coast of circumjacent hill body, cave in and mud-rock flow: Should observe circumjacent hill body has as good as to often be mixed in detail leap, report according to project geology reconnaissance, analyse circumjacent hill body to produce coast possibility.
The examination endangers the main content of gangue library safety inside library area limits: Violate the rules and regulations blows up, quarry and building, violate the rules and regulations undertakes gangue stoping, take water, ab extra gangue, mullock, liquid waste and litter are emited into, depasture and reclaim etc.
