Description

Technical Field

[0001] The present application relates to the technical field of water conservancy and hydropower engineering, and in particular to a box-type water intake structure in a river. Background Art

[0002] Conventional box-type water intake structures in the river all use prefabricated concrete structures. The prefabricated structures are large in size and tonnage, and require a very large prefabrication site on the riverside. Some projects are generally prefabricated in sections due to the high height of the water intake structure. After prefabrication, they need to be towed to the installation waters by large-tonnage ships, and then hoisted and installed in sections by cranes. The prefabricated concrete structure is constructed underwater to connect the structure. It is very difficult to connect the joints of the concrete structure underwater, and the connection quality assurance rate is low. Due to the heavy weight of the prefabricated concrete structure, large-tonnage ships, lifting equipment and other construction machinery are required. At the same time, due to the operation in the river, the construction difficulty is very large. Utility Model Content

In the connected state, the positioning steel pipe pile 4 is sleeved with the positioning steel pipe 2 to fix the steel casing; the concrete pouring layer is at least partially poured on the steel casing to form a water intake structure.

[0043] like Figure 1-2 As shown, in a specific embodiment, the steel casing steel plate 1 includes a supporting channel steel, a first supporting angle steel 7, a second supporting angle steel 8 and a third supporting angle steel 9; the supporting channel steel includes a first supporting channel steel 5 and a second supporting channel steel 6 arranged relatively, the first supporting angle steel 7 is vertically arranged between the first supporting channel steel 5 and the second supporting channel steel 6, the second supporting angle steel 8 is obliquely arranged between the first supporting channel steel 5 and the second supporting channel steel 6, and the third supporting angle steel 9 is arranged on the first supporting channel steel 5 and / or the second supporting channel steel 6.
