Embodiment 1

[0034] Such as Figure 1-3 As shown, the sectional view of the overall upward-swing steel dam water retention state, the sand washing and partial water release state, and the complete water release state provided by the embodiment of the present invention is shown. The overall upward-spinning steel dam includes a retaining dam surface 1, the retaining dam surface 1 is an integral structure, and the back is supported by multiple groups of supporting rotating rods 2, and each group of supporting rotating rods 2 includes multiple rotating rods that rotate around the common hinge support 3 in each group. Roots support rotating rods 2, one end of these supporting rotating rods 2 is connected to the hinge support 3, and the other end is radially connected to the back surface of the dam surface 1. The integral upturn steel dam also includes a hydraulic cylinder 4 connected to the dam surface at the end of the river. One end of the hydraulic cylinder 4 is fixed on the installation par...

Embodiment 2

[0037] Such as Figure 4-5As shown, it shows the rear view elevation view of the integral upward-swivel steel dam provided by the embodiment of the present invention when it is fully released and blocked. Comparing the two pictures, it can be seen that when the overall upper-swing steel dam is raised, the obstruction to the water flow is very small, and when the dam is erected, due to the overall dam surface structure, and the configuration of the water-stop device and the sand washing part, the water-stop effect is good.

Embodiment 3

[0039] Such as Image 6 As shown in FIG. 1 , it shows the three-dimensional display diagram of the overall upturn steel dam provided by the embodiment of the present invention. The overall upward-spinning steel dam includes a dam surface 1 spanning the entire width of the river, the dam surface 1 is an integral structure, the back is supported by multiple sets of supporting rotating rods 2, and each group of supporting rotating rods 2 is along the width direction of the river, etc. The intervals are arranged in parallel, so that the pressure exerted by the overall upward-swivel steel dam on each group of supporting rotating rods is evenly distributed, which is beneficial to improving the structural strength of the steel dam.

[0040] The hinge supports 3 are pre-buried in the dam foundation, and the connecting lines of each hinge support 3 are basically parallel to the dam surface 1 . The above setting means that each group of supporting rotating rods is arranged concentrical...

Abstract

The embodiment of the invention discloses an integrated upward-spiral steel dam in order to overcome the shortcomings of a rubber dam, a hydraulic dam and a steel dam gate in the prior art. Meanwhile,the integrated upward-spiral steel dam is relatively simple in overall structure, scientifically stressed, convenient to overhaul, good in sand washing effect and not limited by water quality, terrain and the width of a river way.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering construction, in particular to an integral upward-swing steel dam. Background technique [0002] At present, there are rubber dams, hydraulic dams, steel dam gates, etc., which are widely used in water conservancy project construction. [0003] The rubber dam is a kind of dam that was widely used in the early days. It does not block water after the dam is released, and the cost is low, but there are also many problems, mainly including: easy to damage, easy to age, long time to rise and collapse, and silt Manual cleaning is required during burial, and the service life is short. [0004] At present, hydraulic dams are widely used in the market and have various forms. The basic features include: the panel is an assembled structure, and each panel is about 6-12 meters wide; there is a side water stop between the panels; each panel is driven by a hydraulic cylinder. , there are...
