This study is about the official pipe body of groundwater development, especially to improve its connection means and provide relevant relationships.In order to connect multiple pipes for groundwater development, a socket is arranged on the outer wall of the connecting part of the pipe body and the pipe body, and the socket and the pipe body are connected with screws.However, if the pipes are connected, additional sockets are needed, so the government 's installation costs will increase, and the external diameter of the pipes will become larger, and the diameter of the drilled pipe holes will also be expanded, The expansion of the diameter of the excavator will inevitably lead to a huge increase in the engineering cost.Therefore, dark connection (2) and water connection (3) are formed at both ends of the official body (1),By connecting the connection part of the neighbor (11), the neighbor (11) is connected,The utility model can reduce the diameter of the pipe body, the diameter of the pipe hole to be chiseled, and the cost of the pipe hole to be chiseled,And do not use more expensive connection with the socket, has the effect of reducing engineering costs.
