Description
Technical Field
The invention relates to the field of building construction, in particular to construction of a concrete wall body of a strip-shaped water pool, and particularly relates to formwork equipment suitable for construction of an ultra-long wall body of more than 400m and an installation method thereof.
Background
At present, the equal thickness of the pool wall of the pool is generally constructed by using a full scaffold and a template. When the cross section of the pool wall changes, a special qualitative standardized template is generally required to be adopted, and compared with the construction of the traditional template, the integral shaping standard block template has the characteristics of high assembly and disassembly speed in construction, convenient template calibration, good overall performance of the template, capability of ensuring the molding quality of the concrete of the pool wall and the like. The main structure of a certain engineering is a semi-buried 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 pool structure are made of C30 concrete, the impervious grade is P8, the thickness of the bottom plate is 1000-1500mm, the thickness of the pool wall is 800-2000mm, and each pool wall section is poured in layers.
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 smoothly transited. (2) The flatness of the inner walls of the two sides of the long side of the pool within any length of 5m is less than or equal to 5mm within the height range of 3400mm from the top of the pool. (3) The flatness requirements of the pool in the whole length range of the long side inner wall surface are included in the long side parallelism requirements, and the flatness requirements of the pool in the whole length range of the short side inner wall surface are included in the short side perpendicularity requirements.
The "cuboid character" requirement of the pool: parallelism of the long side of the pool (for controlling error in the width direction of the pool): a) Height range of 3400mm down the pool roof and length range of 50m before the pool wave maker end: the parallelism of the south side inner wall and the north side inner wall of the pool relative to the longitudinal section in the pool is less than or equal to 5mm; b) Height range of 3400mm down the pool roof and length range outside the front 50m of the pool wave maker end: the parallelism of the south side inner wall and the north side inner wall of the pool relative to the longitudinal section in the pool is less than or equal to 10mm; c) The height range from the top of the pool to the bottom of the pool is 3400mm downwards: the parallelism of the south side inner wall and the north side inner wall of the pool relative to the longitudinal section of the pool is less than or equal to 20mm.
Because the variable cross-section pool wall length exceeds 400 meters, owners and design parties have high quality requirements on the levelness, the inner wall flatness and the like of the pool wall, if a traditional full-hall scaffold and template construction method is adopted, the site construction efficiency is low, flatness adjustment measures are limited, the integrity of the template is poor, and the template installation precision and the template removal can all have influence on the construction progress and the construction quality.
