Description

TECHNICAL AREA

The present invention relates to the technical field of construction of a building project, in particular to an adjustable automatic flattening device for a cone-shaped pool body.

STATE OF THE ART

Cone-shaped pools commonly occur in turbulent grit chambers, sludge thickening ponds, and other parts of sewage treatment plants. Due to the inclination of the cone-shaped surface, impurities or sludge in the water are accumulated to the central part of the pool bottom and treated uniformly, so there is a high requirement for the flatness of the pool body surface. Currently, the usual method is to hold a wooden or aluminum alloy scraper to do the leveling manually. The length of the scraper is about 2m, and the operator can hold the scraper in hand and scrape hard to complete the leveling work. The traditional construction methods are not only slow and labor-intensive, the flatness of the surface is difficult to control, which is greatly influenced by the technical level of the operators. Due to the large slope of the pool wall, the construction is more dangerous.

The pamphlet GB 1 487 833 A describes a method of applying a screed to surfaces. In the pamphlet U.S. 2,435,052 A describes a method for the production of circular, open-topped water tanks made of concrete and a device for it.
