Problems solved by technology

[0004] The baffle includes the upper beam body and the lower plate body. Since the beam body is about 2.6 meters high, and the plate body is an inclined plane, forming an angle of 45 degrees with the beam body, the upper beam body and the lower plate body are usually placed together during pouring. Separate construction will result in construction cold joints at the junction of the beam body and the plate body, and the corrosive wastewater flowing through the baffle will erode the steel bars through the construction cold joints, affecting the structure of the baffle plate, thereby affecting the wastewater treatment effect

Embodiment Construction

[0031] The present invention will be further described below in combination with specific embodiments.

[0032] The method for pouring ABR reaction tank baffles comprises the steps:

[0033] 1) Binding of steel mesh: Bind the double-layer steel mesh with steel bars at the beam body, plate body and armpit of the baffle with a horizontal spacing of 140 mm and a longitudinal spacing of 120 mm; the steel mesh must be bound strictly according to this spacing to ensure that Under the premise of satisfying the structural bearing capacity, prevent stones from getting stuck in the steel bars, and avoid quality defects such as leaking stones and holes; all steel bars in the steel mesh are fully tied to avoid loosening of the steel bars due to the vibration of the vibrating rod. The steel stirrups are bound and positioned between the double-layer steel mesh, and the stirrup is firmly bound to the steel mesh to ensure the distance between the double-layer steel mesh and the thickness of t...

Abstract

The invention discloses a method for pouring an ABR (Acrylate Butadience Rubber) reaction tank baffle. The method comprises the following steps: 1) binding reinforcing bar nets: binding double-layer reinforcing bar nets by using reinforcing bars and binding stirrups between the double-layer reinforcing bar nets; 2) bracing formworks: respectively bracing beam supporting formworks on two sides of a beam reinforcing bar net, bracing plate supporting formworks on two sides of a plate reinforcing bar net, bracing an axilla supporting formwork outside an axilla reinforcing bar net, and meanwhile, supporting and fixing by using a longitudinal supporting rod and a horizontal supporting rod of a scaffold, and fixing and supporting the bottom of the plate reinforcing bar net on a steel tube of the scaffold; 3) pouring concrete: pouring a part below a preformed hole, a part from the preformed hole to the axilla and the beam with concrete layer by layer in turn; and 4) dismounting the formworks: dismounting the formworks when the concrete strength is 100%. The beam and plate of the ABR reaction tank baffle are integrally poured according to the method disclosed by the invention, so that the construction cold seam does not exist between the beam and plate and the forming quality is excellent.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a method for pouring a baffle in an ABR reaction tank. Background technique [0002] The ABR reaction tank is an anaerobic baffle reaction tank. It is a high-efficiency anaerobic reactor. It not only has a strong biological solid retention capacity, but also has good hydraulic mixing conditions. It is often used in various industrial wastewater treatment. It is used in aerobic treatment processes. It converts the refractory organic matter in the wastewater into easily degradable fatty acids, improves the biodegradability of the wastewater, and facilitates the subsequent biochemical treatment. [0003] The baffle is vertically arranged in the ABR reaction tank, which divides the reaction tank into several reaction chambers in series. The waste water enters the reaction tank at a specific flow rate and then flows up and down along the baffle, passing through the sludge of each ...
