Description
Technical Field
The utility model relates to a device that steel cofferdam and pump station combine to arrange belongs to hydraulic engineering facility field.
Background
The hydraulic engineering often needs to newly build a temporary cofferdam to close a construction site to form a dry land construction working face. For river network areas, many inland rivers participate in water circulation through external water sources to ensure the water quality of the inland rivers. A cofferdam is built at a place where an inland river and an external river are connected, an originally communicated water system is cut off after the cofferdam is built, the water quality of the inland river is easy to deteriorate, and waterlogging is easy to form in a flood season.
In order to solve the problem, drainage and water exchange are generally performed by burying a draft tube or erecting a temporary water pump on the bank. The water level difference at the two ends of the flow guide pipe in the plain river network area is very small, and water flow is difficult to flow freely, so the communication effect of the flow guide pipe in the plain area is poor. The temporary water pump usually adopts a submersible sewage pump or an axial flow pump with small single pump flow (the single pump flow is usually 0.1 m)3And less than s), the number of the water pumps is large, and the emergency drainage management is not facilitated.
To solve the above problems, the utility model provides aThe device for arranging the cofferdam and the pump station together improves the rigidity of the foundation and can meet the requirement that the maximum flow of a single pump is 1.5m3The scheme can effectively reduce the number of water pumps, improve the drainage and water exchange efficiency and ensure the water environment and water safety. The mounting platform of water pump has all adopted the steel construction, and the installation is fast with demolising, and demolishs back all materials and all recoverable recycling, has the sustainability.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a device that steel cofferdam and pump station combine to arrange.
A device for arranging a steel cofferdam and a pump station in a combined way comprises: the steel cofferdam pile, the steel-pipe pile, shaped steel platform, 1cm thick steel board, water pump fixing support, outlet pipe.

The section steel platform is formed by welding section steel; and the section steel platform is respectively welded with the steel cofferdam pile foundation and the steel pipe pile foundation through steel plates.
And a water pump is arranged on the profile steel platform to form a temporary pumping station. The water pump adopts a submersible tubular pump; the water pump is fixed by welding a water pump fixing support on the pump shell with the profile steel platform or by utilizing a bolt connection mode. And a water outlet pipe of the water pump is connected with a pipeline, and the water pump discharges water into a foreign river through the pipeline.
The steel pipe piles and the steel cofferdam piles are welded with each other through the section steel platforms to form an integral frame;
the integral frame is fixed on the periphery of the cofferdam along with the steel pipe piles and the cofferdam piles;
the steel plate with the thickness of 1cm is welded between the steel cofferdam pile and the section steel platform;
the steel plate with the thickness of 1cm is welded between the steel pipe pile and the section steel platform;
the wall thickness of the steel pipe pile and the steel pipe cofferdam pile is not less than 8 mm;
