A water treatment device construction structure having a grating room and a method for constructing various water spaces/waterscape facilities having the same coupled thereto are disclosed. The structure relates to a buried water treatment device for treating operation water such as tap water, groundwater, rainwater, and surface water through an environment-friendly method. A water treatment device construction structure having a grating room is coupled to civil engineering/landscaping facilities, or to fish farms that are to be constructed in view of the purpose of construction and productivity. The water treatment facility having a reservoir coupled thereto is provided in a predetermined position below facilities or on the lower-end or peripheral portion thereof in a buried/underground type. Accordingly, there is no burden in site selection; a large amount of operation water can be stored without degrading the aesthetic landscape; and natural energy can be used preferentially.

A wall sinking construction method comprises retaining structures are first formed on two sides, corresponding to a groove body, of the wall body; then a section of wall body of a certain height is produced on the ground, and jacks and a supporting pile body are installed on the two sides of the bottom of the wall body that is supported by the jacks and the supporting pile body, the bottom of the wall body is suspended to form an excavation working space with a certain height; an underwater excavator is controlled remotely to excavate rock and soil in the groove body layer by layer; an elastic support having rollers is sandwiched between the retaining structures on the two sides of the wall body and the groove body to transfer and balance rock and soil pressure.

A corner connecting structure for a box-like pipeline or container of corrugated steel plates comprises a pipeline formed by assembling corrugated steel wall plates. The planes of every two adjacent corrugated steel wall plates intersect along a straight line, and the corrugation directions of the corrugated steel wall plates are perpendicular to the line of intersection. At least one corrugated steel wall plate is composed of a first corrugated steel plate and a second corrugated steel plate, of which the corrugation directions are perpendicular to the line of intersection. An end surface of the first corrugated steel plate perpendicular to the corrugation direction and coplanar with the line of intersection intersects and is fixed to the second corrugated steel plate, and is then attached and connected to the adjacent corrugated steel wall plate through the second corrugated steel plate.

An idea to use prefabricated modular space unit (FIG. 1) that can be used singularly or combined in plurality (FIG. 2) to form mega floating or underwater architectural buildings & civil structures and support systems for human civilisation.
