The invention relates to the technical field of hydraulic engineering water retaining, and discloses a hydraulic engineering construction water retaining device which comprises a concrete upstream water retaining prefabricated seat and a concrete downstream water retaining prefabricated seat, and a temporary flow guide unit is arranged between the concrete upstream water retaining prefabricated seat and the concrete downstream water retaining prefabricated seat; the temporary flow guide unit comprises a water inlet pipe arranged on the concrete upstream water retaining prefabricated seat, a flow guide box arranged between the concrete upstream water retaining prefabricated seat and the concrete downstream water retaining prefabricated seat, a transverse plate and a vertical plate which are arranged in the flow guide box, and a water outlet pipe arranged on the box wall of the flow guide box; and the drainage hose is arranged between the water outlet pipe and the concrete downstream water retaining prefabricated seat. According to the water retaining device for water conservancy project construction, a riverbed at the water conservancy building construction position can be continuously kept dry to facilitate construction, a diversion channel and a diversion tunnel do not need to be built, and the construction strength and cost are reduced.

本发明涉及水利工程挡水的技术领域，公开了一种水利工程施工挡水装置，包括混凝土上游拦水预制座和混凝土下游拦水预制座，混凝土上游拦水预制座和混凝土下游拦水预制座之间设置有临时导流单元；临时导流单元包括：设置于混凝土上游拦水预制座上的进水管，设置于混凝土上游拦水预制座和混凝土下游拦水预制座之间的导流箱，设置于导流箱内的横板和竖板，设置于导流箱箱壁上的出水管，以及设置于出水管和混凝土下游拦水预制座之间的排水软管。该水利工程施工挡水装置，使得水利建筑施工位置的河床可以持续保持干燥便于施工，而且不需要修建导流明渠和导流隧道，降低了施工强度和成本。
