Please note that in order to clearly show the structure of various components of the embodiments of the utility model, the drawings are not drawn according to the same scale. The same reference numerals are used to represent the same parts.
[0026] A schematic diagram of a rigid waterproof structure at the bottom of a river channel according to the utility model is shown in FIG. Figure 1 The rigid waterproof structure at the bottom of the river channel includes a sand and gravel layer 10 , which is arranged along the bottom contour of the river channel. FS102 waterproof compacting agent is arranged inside the sand and gravel layer 10 to enhance the compactness of the sand and gravel layer 10 . Figure 1 In the illustrated embodiment, the gravel layer 10 is disposed above the soil layer, thereby forming a first protective layer above the soil layer.
[0027] Furthermore, a concrete layer 20 is arranged above the sand and gravel layer 10 , and a FS102 waterproof compacting agent is also arranged inside the concrete layer 20 to enhance the compactness of the concrete layer 20 .
[0028] In the present invention, the volume content of FS102 waterproof compacting agent in the concrete layer 20 is greater than the volume content of FS102 waterproof compacting agent in the gravel layer 10. Since the concrete layer 20 is closer to the river, better compactness needs to be ensured. The above arrangement can prevent the river from leaking into the soil layer through the concrete layer 20 and the gravel layer 10.
[0029] Preferably, the volume content of the FS102 waterproof compacting agent in the concrete layer 20 is greater than 5% to ensure the compactness of the concrete layer 20.
[0030] Figure 2 In the embodiment, a waterproof layer 30 is arranged above the concrete layer 20 , and a waterproof reinforcement layer 40 is arranged at the junction of the waterproof layer 30 and the concrete layer 20 .
[0031] Furthermore, the concrete layer 20 is arranged along the outer contour of the sand and gravel layer 10 , and the thickness of the concrete layer 20 is smaller than the thickness of the sand and gravel layer 10 .
[0032] As an embodiment of the present invention, the waterproof layer 30 is a waterproof coiled material, which is laid along one end of the river channel toward the other end of the river channel.
[0033] Meanwhile, there are multiple waterproof layers 30, which are stacked and laid along the length direction of the river channel.
[0034] Furthermore, the waterproof layer 30 is a polymer waterproof coiled material with a thickness of 3 mm or 5 mm.
[0035] Figure 1 In the embodiment shown, the waterproof layer 30 covers the bottom of the river channel, which covers at least 40% of the depth of the river channel. Preferably, the waterproof layer 30 covers the bottom of the river channel and covers 50% of the depth of the river channel to form a rigid waterproof structure at the bottom of the river channel.
[0036] Furthermore, the waterproof reinforcement layer 40 is a FS101 mortar waterproof layer, which is applied at the junction of the waterproof layer 30 and the concrete layer 20 to form a combined waterproof structure to prevent river water from leaking into the soil layer and scouring the river channel.
[0037] As an embodiment of the present invention, the thickness of the waterproof reinforcement layer 40 is 1-3 mm; preferably, the thickness of the waterproof reinforcement layer 40 is 2 mm to enhance the waterproof performance at the junction of the waterproof layer and the concrete layer.
[0038] Furthermore, the volume content of the FS101 mortar waterproofing agent in the FS101 mortar waterproofing layer is greater than or equal to 8%, so that the waterproofing reinforcement layer 40 is used to enhance the waterproofing property of the junction between the waterproofing layer 30 and the concrete layer 20 .
[0039] Compared with the shortcomings and deficiencies of the prior art, the utility model provides a rigid waterproof structure at the bottom of the river channel, which has a reasonable structure. FS102 waterproof compacting agent is arranged inside the sand and gravel layer and the concrete layer to enhance the compactness of the sand and gravel layer and the concrete layer; at the same time, a waterproof layer formed by a waterproof membrane is arranged above the concrete layer, and a waterproof reinforcement layer formed by FS101 waterproof mortar is arranged at the junction of the waterproof layer and the concrete layer to form a rigid waterproof structure at the bottom of the river channel to prevent river water from eroding the river channel.
