Construction method and construction device of mud collecting bucket in sedimentation tank

Abstract

The invention provides a construction method and a construction device for a mud collection bucket in a sedimentation tank. The construction method includes the steps of: making a square platform frame of a corresponding specification according to the specifications of the mud collection bucket to be formed; reinforcing the square platform frame to collect mud in the sedimentation tank The bucket part, and make the four side beams of the four-sided platform frame one by one fixed on the four side edges of the mud collecting bucket; mix the dry hard concrete; lay the dry hard concrete layer by layer between the side wall of the sedimentation tank and the side beams and tamping, so that the dry hard concrete filled in the sedimentation tank forms a mud bucket. The invention controls the specifications of the mud collecting bucket through the positioning of the four-sided platform frame, and uses dry hard concrete for filling construction to obtain the mud collecting bucket. The four-sided platform frame occupies a small volume, which is convenient for support and dismantling, and reduces the construction positioning device of the mud collecting bucket. The difficulty of reinforcement and disassembly reduces the intensity of manual labor, thereby reducing the difficulty of construction and improving construction efficiency. At the same time, the four-sided platform frame uses less material, which is convenient for processing, saves a lot of templates, and reduces costs.

Description

technical field [0001] The invention relates to the technical field of building construction, and more specifically, relates to a construction method for a mud collection bucket in a sedimentation tank, and also relates to a construction device for a mud collection bucket in a sedimentation tank. Background technique [0002] In order to meet the process design in the municipal engineering of water purification plants, the mud collecting bucket in the sedimentation tank is a concave inverted quadrangular platform concrete structure with a large upper part and a smaller lower bottom, that is, an inverted quadrangular platform-shaped funnel structure is formed to realize the mud collecting bucket. Mud collection and concentration function. [0003] The water purification workshop is generally equipped with multiple groups of flocculation and sedimentation tanks. Each group of flocculation and sedimentation tanks has eight square-edged mud collection buckets with a height of 2....

Problems solved by technology

[0005] However, the formwork of the above-mentioned quadrangular platform box occupies a large volume and is not convenient for supporting, and the formwork of the quadrangular platform box body is not easy to remove after the concrete pouring is completed, thereby increasing the difficulty of reinforcement and disassembly of the quadrangular platform box body , thus increasing the construction difficulty and affecting the construction efficiency

At the same time, the area of ​​the template is large, which is not convenient for processing, and there are many consumables, which increases the cost

[0006] In addition, the concrete needs to be poured in layers during the construction process, and the next layer of construction can only be carried out after the initial setting of the bottom layer of concrete is completed. Leading to more horizontal construction joints, which affects the quality of pouring molding

Moreover, in the process of concrete pouring, the formwork of the square box has poor anti-floating ability, and it is more prone to mold explosion.
