The main structure of a certain project is a semi-buried water pool with the length of 400 meters, the width of 18 meters and the depth of 10.3 meters, the bottom plate and the pool wall of the water pool structure are made of C30 concrete, the anti-permeability grade is P8, the thickness of the bottom plate is 1000-1500mm, the thickness of the pool wall is 800-2000mm, and each section of the pool wall is poured in a layered mode.
The flatness requirement of the inner wall of the pool is as follows: (1) the flatness of the joints of all the templates is less than or equal to 2mm and the templates are in smooth transition. (2) The height of the pond top is 3400mm, and the planeness of the inner walls of the two sides of the long sides of the pond in any length range of 5m is less than or equal to 5 mm. (3) The flatness requirement in the whole length range of the inner wall surface of the long side of the pool is included in the parallelism requirement of the long side, and the flatness requirement in the whole length range of the inner wall surface of the short side is included in the verticality requirement of the short side.
The 'cuboid character' of the pool requires: pool long edge parallelism (to control errors in pool width direction): a) the height range of the pool top is 3400mm downwards and within the length range of 50m in front of the pool wave maker end: the parallelism of the south inner wall and the north inner wall of the water pool relative to the longitudinal section in the water pool is less than or equal to 5 mm; b) the height range of the pool top is 3400mm downwards and the length range is outside 50m before the pool wave making end: the parallelism of the south inner wall and the north inner wall of the water pool relative to the longitudinal section in the water pool is less than or equal to 10 mm; c) the height range from the top of the tank to the bottom of the tank is 3400 mm: the parallelism of the south inner wall and the north inner wall of the water pool relative to the longitudinal section in the water pool is less than or equal to 20 mm.
