Embodiment Construction
[0014] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.
[0015] Such as Figure 1-2 As shown, the water intake structure arranged in combination with the shaft cofferdam of the present invention includes a shaft cofferdam 1, a water intake tower body 2, a trash rack storehouse and a stacked beam door storehouse 3, a door crane track beam 4, and a water intake 7. The water intake tower body 2 is arranged inside the shaft cofferdam 1, the cavity between the shaft cofferdam 1 and the water intake tower body 2 is arranged with a trash rack storehouse and a stacked beam door storehouse 2, and the portal crane track beam 4 exceeds the shaft cofferdam 1 The p...

The invention discloses a water intake building combined with a shaft cofferdam for permanent and temporary combination layout. The water intake building comprises the shaft cofferdam, a water intake tower body, a trash rack storeroom, a stoplog gate storeroom and a crane rail beam. The water intake tower body is arranged inside the shaft cofferdam, and the trash rack storeroom and stoplog gate storeroom are arranged in a cavity between the shaft cofferdam and the water intake tower body. A cantilevered structure is applied on the part, beyond the shaft cofferdam, of the crane rail beam. A water intake is formed in the late period of demolition of an upstream channel part of the shaft cofferdam. By utilizing the water intake building combined with the shaft cofferdam for permanent and temporary combination layout, the water intake building is compact in layout, economical and practical; the water intake building can meet the layout requirement and function of the water intake, and can also reduce the size of cofferdam, reduce the difficulty of construction and ensure safety; the engineering quantity is reduced. The water intake building can be widely applied to water intake construction projects in the environments where reservoirs are built for water intaking and geological conditions are poor.
Description
technical field [0001] The invention relates to a water intake of a water conservancy and hydropower project, in particular to a water intake structure permanently arranged in combination with a shaft cofferdam. Background technique [0002] In order to solve the problems of local water shortage, drought resistance, etc., so that water resources can be rationally allocated, more and more water diversion and water diversion projects, most of which need to divert water from the built reservoir area, the reservoir is at a high water level all year round, and the reservoir bank is conglomerate + Mudstone does not meet the conditions for building water intakes in caverns. If a conventional tower-type water intake structure is adopted, the design and construction of water retaining cofferdams will be very difficult, and the project investment will also be large. Contents of the invention [0003] The purpose of the present invention is to provide a water intake structure permane...
