①Required conditions before full water test
(1) The mortar of the concrete or brick and stone masonry of the pond has met the design strength requirements; the pond is cleaned and clean, and the defects inside and outside the pond have been repaired.
(2) Before the construction of the waterproof layer and corrosion-proof layer of the cast-in-place reinforced concrete pool body; after the pre-stressed concrete is applied to the prefabricated prestressed and the anchor end is sealed with
, before the protective layer is sprayed; after the construction of the brick-built pool body waterproof layer, after the joints of the stone-built pool body are grouted.
(3) The design reserved holes, embedded pipe ports and water inlets and outlets have been temporarily sealed, and experience can safely withstand the test pressure.
②Test process
Test preparation → Pool water injection → Water level observation in the pool → Evaporation measurement → Collect test conclusion
③Test requirements
Injection of water into the pool should be carried out in 3 times, each time the water injection is 1/3 of the designed water depth. For large and medium-sized pool bodies, water can be poured first above the construction joint at the bottom of the pool wall, and check the anti-seepage quality of the bottom plate. When there is no obvious leakage, continue to pour water until the first water injection depth.
When filling water, the water level should not rise more than 2m/d. The interval between two adjacent water injections should not be less than 24 hours.
After injecting water to the designed water depth for 24 hours, start to measure the initial reading of the water level stylus (the accuracy should be 1/10mm).
The interval between the initial reading and the last reading of the water level should be no less than 24 hours.
measurement time must be continuous. When the measured water seepage amount meets the standards, it must be measured more than twice in a row.
④Full water test standard
(1) The water seepage amount of the pool is calculated based on the wet area of the pool wall (excluding the inner partition wall) and the bottom of the pool.
(2) Water seepage qualified standard. reinforced concrete structure water tank shall not exceed 2L/(m2• d); masonry structure water tank shall not exceed 3L/(m2• d).
