Embodiment 2

[0043] Embodiment 2. The difference between embodiment 2 and embodiment 1 is that one side of the foldable water-stop structure along the stretching direction of the inner water-retaining plate is connected to the surface of the inner water-retaining plate, and the other side is connected to the supporting plate. Or be connected on the inner wall of the triangular steel box perpendicular to the inner water retaining plate, and the water stop installation groove and the inner water retaining plate and the water retaining plate track are staggered to avoid interference.

[0044] In other embodiments, the middle water retaining part may also be an arched water retaining structure surrounded by more than two steel boxes. In addition, it is also possible to set the traveling mechanism on the rectangular steel box unit and the triangular steel box at the same time.

Abstract

The invention relates to an adjustable water cofferdam. The adjustable water cofferdam comprises a middle water retaining part used for retaining water in the width direction of a canal and two end water retaining parts arranged on two sides of the middle water retaining part respectively, wherein each end water stopping part comprises a fixed tank body and an inner water retaining structure mounted in the fixed tank body; the inner water retaining structure comprises an inner water stopping plate and a water stopping plate driving structure used for driving the inner water stopping plate to stretch and retract, and a foldable water stop structure used for spacing inside space of the fixed tank body in the stretching and retracting direction of the inner water retaining plate is arranged between the inner water retaining plate in the fixed tank body and the fixed tank body. When the water cofferdam is used on a lower slope, the inner water retaining plates in the end water retaining parts can be opened up to make up the insufficient height of the fixed tank bodies, and water is prevented from entering the inner side of the water cofferdam by passing by the inner side of the inner water retaining plates. Compared with the prior art, the adjustable water cofferdam can be adapted to slopes with more gradients and is wider in use range.

Description

technical field [0001] The invention relates to a water cofferdam, in particular to an adjustable water cofferdam applicable to slopes with different slope ratios. Background technique [0002] Since the main line project of the middle line of the South-to-North Water Diversion Project was opened to water, the water receiving areas along the line have had a strong dependence on the water source of the middle line of the South-to-North Water Diversion Project. However, some quality defects such as cracks, uplifts, and collapses have begun to appear on the lining panels of some channels of the main canal. Although such problems will not affect the normal water operation of the main canal in a short period of time, they will affect the overall stability of the side slope of the canal. Sex is extremely unfavorable. As the main canal currently does not have the conditions for water suspension and maintenance, quality defects such as subsidence and uplift of the lining panels bel...
