Construction method of high liquid level concrete slab-shell composite water treatment structure

Abstract

The invention discloses a construction method of a high liquid level concrete slab-shell composite water treatment structure. The construction method comprises the following steps: determining the scale of the high liquid level concrete slab-shell composite water treatment structure (1) and a foundation treatment scheme according to the occupied area and site classification of the to-be-constructed water treatment structure and a geotechnical engineering investigation report; paving a lime and clay cushion course (2) and a pebble bed (3), and pouring a plain concrete cushion course (4), wherein in the lime and clay cushion course (2), the volume ratio of lime to clay is 3:7, and in the pebble bed (3), the particle sizes of the pebbles are uniform; configuring a bottom plate (5), outer poolwall plates (6), outer pool wall beams (7), outer pool wall columns (8), an inner cylindrical shell (9) and rebars of inner cylinder ring beams (10); arranging embedded parts at the joint of the outer pool wall beam (7) and the outer pool wall column (8), arranging the embedded parts at the corresponding positions of the inner cylinder ring beam (10), erecting a template, and pouring concrete, wherein the number of the embedded parts at the corresponding positions of the inner cylinder ring beam (10) is the same as that of the embedded parts at the joint of the outer pool wall beam (7) and the outer pool wall column (8); and additionally arranging a radialized section steel beam support (11) and mounting accessory equipment of the water treatment structure.

Description

technical field [0001] The invention relates to a water treatment structure, in particular to a concrete slab-shell composite water treatment structure technology with small footprint and high liquid storage level. Background technique [0002] Water is the source of life, and the fresh water resources that we humans rely on for survival only account for about 3% of the total water on the earth, and about 78% of them are covered by glaciers and are difficult to use. The fresh water resources we can actually use are very limited, and the increasing demand for agricultural, industrial and urban water supply has exacerbated the shortage of fresh water resources, and these fresh water resources are constantly threatened by various pollutions. Nowadays, the shortage of fresh water resources and pollution have become a worldwide problem faced by all mankind, especially in our country. Although the traditional water treatment structure can solve the water pollution problem to a ce...
