The invention discloses a sand filling pipe device for opposite-pull construction. The sand filling pipe device comprises a plurality of sand filling pipelines, plastic hoses and steel valves. The sand filling pipelines comprise a plurality of sand filling pipes which are connected in sequence. Each sand filling pipe is provided with a float bowl. The sand filling pipelines are connected through the steel valves. Each steel valve is provided with flow divider valves. Each sand filling pipeline is sleeved with the corresponding plastic hose, and one end of each plastic hose is fixedly connected with the corresponding steel valve. By the adoption of the sand filling pipe device, the problem that in the opposite-pull construction process, it cannot be guaranteed that all the portions of a through-long sand bag are filled with sand due to the fact that the through-long sand bag is too long is completely solved, and the plumpness and uniformity of the underwater-formed through-long sand bag are guaranteed.
