Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4The utility model discloses an embodiment of a water retaining device for water conservancy construction, which comprises a plurality of steel sheet piles 1 inserted into a riverbed, a fixing sleeve 5 fixedly welded to the inner side of the steel sheet pile 1, an insertion slot 8 vertically formed in the inside of the fixing sleeve 5, the top end and the bottom end of the insertion slot 8 being in an open structure, a support mechanism inserted into the inner wall of the insertion slot 8, an I-beam 2 fixedly installed at the top end of the support mechanism, a first circular hole 4 formed in the web of the I-beam 2 and connected to the support mechanism, and a support rod 3 welded between the mutually close side plates of the two I-beams 2.

[0019] In the embodiment, after the steel sheet piles 1 are driven into the riverbed and the water retaining steel sheet piles 1 are connected to each other through the linkage structures at the edges, the steel sheet piles 1 have river water therebetween. Before the river water is pumped out, the I-beams 2 and the support rods 3 need to be installed on the inner sides of the two groups of water retaining steel sheet piles 1 to form stable support, so as to avoid the water retaining steel sheet piles 1 from being collapsed under the pressure of the river water outside after the river water is pumped out. Before the river water is pumped out, the support mechanism is inserted into the inner cavity of the insertion slot 8 from top to bottom. After the insertion is completed, the support mechanism is assembled. Then, the I-beam 2 is connected to the support mechanism. After the connection is completed, stable support is formed. At this time, the river water on the inner sides of the two groups of water retaining steel sheet piles 1 can be pumped out for construction.

[0020] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the support mechanism comprises an insertion plate 6 extending from above the fixing sleeve 5 into the inside of the insertion slot 8 and extending below the fixing sleeve 5, the top of the insertion plate 6 is integrally formed with an anti-disengagement plate 7, the support mechanism further comprises a support plate 9 connected to the side of the insertion plate 6 away from the steel sheet pile 1, and the side top end and the side bottom end of the support plate 9 close to the insertion plate 6 are both welded with a fixing lug 11.

[0021] In the embodiment, when the support mechanism is installed, the insertion plate 6 is inserted from above the insertion slot 8 until the insertion of the insertion plate 6 is completed. At this time, the bottom end of the anti-disengagement plate 7 is in contact with the top end of the fixing sleeve 5. At this time, the insertion plate 6 cannot move downward any more. Then, according to the installation position of the I-beam 2, the support plate 9 is placed at a preset height, the second circular hole on the fixing lug 11 is aligned with the threaded hole 10, and the fixing lug 11 is fixed by using a locking bolt. After the fixing is completed, the I-beam 2 is placed on the top of the support plate 9.
