Quality inspection and acceptance of spillway, tailings pipe (tank) and return pipe (tank)

(1) Main points of quality inspection and acceptance of spillway
1. Check the quality of the foundation trench excavation and check the middle. The quality requirement is: the rock surface undulation should be less than 150mm. The surrounding rock should not have obvious explosion rupture gap.
2. A spillway with a masonry should be flat and the thickness of the masonry should not be negative. The masonry stone surface must not have 212 1G420000 mining project construction management sheet stone on the surface, the seam mortar should be full. The concrete facing should be vibrated and compact, with a honeycomb surface and a surface crack.
3. The allowable deviation of the section size of the spillway is 3% of the soil; the allowable deviation of the longitudinal slope is 10% of the soil of the designed slope.
(II) Key points for quality inspection and acceptance of tailings pipe (slot) and return pipe (slot)
1. The elevation and slope of the longitudinal section of the pipe (slot) meet the requirements; the compressive strength and tightness of the pressure pipe meet the requirements; the section size and masonry quality of the flow channel meet the requirements.
2. The allowable deviation of the pipe (groove) laying slope is ±10% of the design slope.
3. The allowable deviation of the net section size of the runner is ±2% of the design size; the wall thickness deviation of the groove should not be negative.
4. The anti-corrosion layer should be inspected for its appearance and thickness, and the adhesion test should be carried out. If necessary, the insulation performance should be checked with a spark tester.
