Embodiment Construction
[0028] A filter plate used for a denitrification filter tank, which is formed by splicing 12 rectangular parallelepiped prefabricated filter plates 2 into one body. The prefabricated filter plates are respectively pre-embedded with annular steel bars 4 on both sides of the length direction, and the adjacent prefabricated filter plates are in the length direction. A filter beam 3 is provided at the seam in the direction. The top of the filter beam is also pre-embedded with an annular steel bar 4, and the longitudinal force steel bar 10 is inserted into the annular steel bar of the adjacent prefabricated filter plate and the annular steel bar at the top of the filter beam. The steel bars are arranged in a staggered manner, and the longitudinally stressed steel bars are bound and fixed on the upper part of the corresponding circular steel bars.
[0029] And a fine stone concrete pouring structure 11 is arranged between the joints in the longitudinal direction of the adjacent pref...

Abstract
The invention relates to construction of an assembled component in the structure engineering construction, in particular to a filter plate for a denitrification filter tank and an installation methodthereof, and belongs to the technical field of building engineering construction. A factory prefabricated filter plate is adopted; annular reinforcing steel bars are reserved on two sides of the filter plate; annular reinforcing steel bars are reserved on a filter beam; the annular steel bars in two places are arranged in a staggered manner; after assembling, the longitudinal load-bearing reinforcing steel bars are inserted into the circular reinforcing steel bars; the C35 micro-expansion fine stone concretes are poured at an abutted seam; a gap of 30 mm is reserved on the upper part of the abutted seam in the width direction and is embedded with a two-component polysulfide sealing paste. According to the filter plate for the denitrification filter tank and the installation method thereofdisclosed by the invention, through installation of the prefabricated filter plate, the working efficiency is greatly improved; the construction period is effectively guaranteed; the steel template material expense, the revolving material rental expense and the later laminating, heat preservation and maintenance expenses of the cast-in-place component are saved; the building waste and the noise pollution are reduced in the construction site; the obvious advantages of energy conservation and environmental protection are provided; in the construction of the filter plates, the quality is reliable, the technology is advanced and the requirement of process use is satisfied.
Description
technical field [0001] The invention relates to the construction of assembled components in the engineering construction of structures, in particular to a filter plate used in a denitrification filter tank and an installation method thereof, belonging to the technical field of construction engineering. Background technique [0002] The essence of the denitrification filter to treat sewage is to use the metabolic activities of various microorganisms on the biological filter material to absorb and degrade pollutants to achieve the purpose of purifying water quality. In the anoxic environment, the nitrogen in the sewage is denitrified, and some organic matter in the sewage is degraded at the same time. The assembled filter plate is the core component of the denitrification filter. It not only needs to isolate the biological filter material for filtration and interception, but also needs to perform air and water backwashing to regenerate the filter capacity of the filter. The c...
