Concrete connecting rods 10201 are arranged inside both of the two concrete bases 102, and the first bentonite waterproof blanket 200 is fixed on the upper end surface of the concrete connecting rod 10201 through the first fixing nail 101;

[0030] The rivets 109, which are installed below the inside of the main body 100 of the river channel foundation, there are several rivets 109, and inclined plates 110 are arranged on the left and right sides of the outer walls of several rivets 109.

[0031] When laying the waterproof blanket on the main body 100 of the riverbed foundation, first lay it in the depressions in the main body 100 of the riverbed foundation. Before laying, first install the rivets 109 and the inclined plates 110 inside the foundation, and then lay the second bentonite waterproof blanket 300 flat in the middle of the main body 100 of the riverbed foundation. After laying, pass the fourth fixing nails 108 from the upper end face to the lower end face of the second bentonite waterproof blanket 300, so that the fourth fixing nails 108 are interference-connected with the rivets 109, thereby fixing the second bentonite waterproof blanket 300. Pour the concrete base 102 inside both sides of the main body 100 of the riverbed foundation, and then pour the concrete connecting rod 10201 on the inner wall of the concrete base 102, so that when the first bentonite waterproof blanket 200 is installed on both sides of the main body 100 of the riverbed foundation, there are firm fixing points.

[0032] Embodiment 2

[0033] Please refer to Figure 1 , a groove cavity 107 is arranged inside the end face of the second bentonite waterproof blanket 300, a fourth fixing nail 108 is arranged inside the groove cavity 107, the lower end head of the fourth fixing nail 108 penetrates and extends into the inside of the rivet 109, and the lower end head of the fourth fixing nail 108 is interference-connected with the inside of the rivet 109.
