Background
The ship lock is a navigation building for ships to overcome the fall of concentrated water level, and is the most applied navigation building in water conservancy and water transportation engineering. When the ship moves upwards, the water level of the lock chamber of the ship lock is discharged to the water level of the downstream, the lower gate is opened, the ship lock enters the lock chamber of the ship lock, the lower gate is closed, water is filled into the lock chamber from the upstream to the water level of the upstream, the upper gate is opened, and the ship leaves the lock chamber and enters the upstream channel. And the reverse is true when the ship descends.
The lock water delivery gallery is an important component of lock engineering, is complex in structure and large in volume, and is a typical special-shaped large-volume concrete structure. The water delivery gallery is a main facility for completing water filling and draining of the ship lock, the flow velocity of water flow is high, the water flow is in a turbulent flow state, and the main problems are two aspects.
(1) Insufficient durability
The insufficient durability mainly shows that the cracks are more and the impact resistance and the wear resistance are insufficient. The crack quality of the lock water delivery gallery is generally known. The concrete on the inner wall of the water conveying gallery is greatly scoured and abraded by water flow, and the possibility of cavitation damage exists locally. Through investigation, the water delivery gallery has common sites of cracks, abrasion and cavitation erosion.
(2) The construction is complicated
The water delivery corridor is of a special-shaped structure, a steel template needs to be customized, the steel template is dismantled after concrete is poured, and construction is complex. The construction period is long and the progress is slow. The construction temporary measure costs are high.
Chinese utility model patent (publication No. CN203821347U) discloses a reinforced concrete prefabricated gallery structure of a roller compacted concrete dam in 2014, wherein an abnormal concrete layer is arranged between the prefabricated gallery and roller compacted concrete of a dam body; the prefabricated corridor is formed by pouring longitudinal stressed steel bars, circumferentially distributed steel bars and concrete. The utility model discloses an adopt full section muscle precast corridor structure of coagulating, although can effectively reduce corridor construction cycle in the long distance dam, still need arrange more vertical and circumferential reinforcing bar, also relatively loaded down with trivial details.
