[0026] In order to make the purpose, technical solution and beneficial effects of the utility model more clear, the technical solution of the utility model is further described below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0027] In the embodiment of the present utility model, Figure 1-Figure 4 As shown, the flood embankment protection device includes: a first waterproof membrane 1, a second waterproof membrane 2 and a plurality of tie structures 3; the second waterproof membrane 2 covers the first waterproof membrane 1, and a closed grouting cavity is constructed between the first waterproof membrane 1 and the second waterproof membrane 2, and the grouting cavity is provided with a grouting port 4 for injecting cement slurry; a plurality of tie structures 3 are arranged in the grouting cavity at intervals in the transverse and / or longitudinal direction, and the tie structure 3 includes two fixing seats provided on the first waterproof membrane 1 and the second waterproof membrane 2, and a connecting rope 307 connecting the two fixing seats, and the connecting rope 307 has a relaxed state in a bent state in a natural state, and a straight tensioned state in an expanded state after the cement slurry is filled in the grouting cavity.

[0028] Specifically, in the embodiment of the utility model, the four sides of the first waterproofing membrane 1 and the four sides of the second waterproofing membrane 2 are closely attached to form a closed grouting cavity, and a grouting port 4 is opened on the grouting cavity to inject cement slurry therein, so as to expand the grouting cavity; the waterproofing membrane is fixed to the flood embankment, and because the cement slurry has a larger bulk density than the water, it will extend to the bottom of the flood embankment and closely attach under the action of its gravity, and after the cement slurry solidifies, a double-layer waterproofing structure layer with sufficient strength can be formed, thereby improving the strength and water-proof property of the flood embankment. In addition, the use of waterproofing membrane can, on the one hand, play a waterproofing role, and on the other hand, it can be convenient to customize the size of the grouting cavity according to the size of the flood embankment. At the same time, in order to fix the waterproofing membrane to the flood embankment, corresponding brackets and / or ropes can be added to the flood embankment to fix and support the waterproofing membrane.

[0029] In the embodiment of the utility model, a plurality of tie structures 3 are arranged in the grouting cavity, and the plurality of tie structures 3 are equidistantly arranged in a linear array in the transverse and longitudinal directions. The tie structure 3 includes two fixing seats and a connecting rope 307 connecting the two fixing seats. The two fixing seats are respectively fixed at the opposite end surfaces of the first waterproof membrane 1 and the second waterproof membrane 2. The connecting rope 307 can be set with a corresponding length according to the size of the grouting cavity, and forms a tensioned state after the grouting cavity expands, so as to connect the two waterproof membranes to balance their forces and enable the grouting cavity to be always in a closed state.

[0030] The utility model sets a double layer of waterproofing coiled material so that a grouting cavity for injecting cement slurry can be constructed therebetween. Thus, when water seepage occurs on the flood embankment, the device can be fixed to the corresponding position of the flood embankment (the second waterproofing coiled material 2 is attached to the flood embankment), achieving the purpose of double waterproofing. In addition, after the waterproofing coiled material is installed and fixed, cement slurry is injected into the grouting cavity. The length and / or width of the waterproofing coiled material can be customized according to the actual size of the flood embankment, which not only improves the versatility of the device, but also facilitates transportation and installation. Furthermore, the two waterproofing coiled materials are connected by a tie structure 3 to improve the structural stability of the protective device.

[0031] like Figure 4-Figure 6 As shown, in one embodiment, the fixing seat includes a detachably connected locking portion 301 and a matching portion 304, and the locking portion 301 is provided with a hanging ring 302 for connecting the connecting rope 307. Specifically, in order to facilitate the two ends of the connecting rope 307 to be wound around the corresponding fixing seat, the fixing seat is defined as a detachably connected locking portion 301 and a matching portion 304, and the locking portion 301 is integrally formed with a hanging ring 302, so that the connecting rope 307 is fixed to the hanging ring 302 after being knotted, and the matching portion 304 is fixed to the corresponding waterproof coiled material; at the same time, the locking portion 301 and the matching portion 304 are detachably connected, so that the connecting rope 307 is knotted and fixed to the locking portion 301 outside the grouting cavity, and then fixed to the matching portion 304 through the locking portion 301, which is convenient for transportation and installation.

[0032] Furthermore, if Figure 4-Figure 6 As shown, in one embodiment, the opposite end surfaces of the locking portion 301 and the matching portion 304 are respectively provided with a matching buckle 303 and a slot 305, and the buckle 303 is detachably engaged with the slot 305. Specifically, in order to achieve a detachable connection between the locking portion 301 and the matching portion 304, this embodiment provides a buckle 303 and a slot 305 on the opposite end surfaces of the two, so that the buckle 303 is engaged with the slot 305 to achieve a detachable connection between the two. Of course, the installation positions of the buckle 303 and the slot 305 can be interchanged. Figure 5 As shown, the buckle 303 is formed with a groove with an opening 306 facing downward; Figure 6 As shown, the card slot 305 is formed with a groove with an opening 306 facing upward, and the two grooves can be engaged to achieve fixation. Figure 6 As shown, the bottom of the slot 305 is provided with an opening 306 for avoiding the buckle 303, so that the end of the buckle 303 protrudes outside the bottom of the slot 305, so that the two are in close contact. Of course, a friction layer can also be provided at the contact end surface of the buckle 303 and the slot 305 to increase the friction between the two.

[0033] like Figure 1As shown, in one embodiment, the first waterproofing membrane 1 is provided with a plurality of reinforcing ribs 5 at intervals along the longitudinal direction, and the reinforcing ribs 5 extend in the transverse direction. Specifically, in order to improve the structural strength of the first waterproofing membrane 1 and constrain the cement slurry in the grouting cavity, the present embodiment provides a plurality of reinforcing ribs 5 on the first waterproofing membrane 1, and the plurality of reinforcing ribs 5 are provided at intervals along the longitudinal direction, and each reinforcing rib 5 extends in the transverse direction; in this way, after the cement slurry is injected, its deformation can be constrained to prevent bulging. Preferably, the projection of the fixing seat is at least partially located on the reinforcing rib 5; that is, the projection of the matching portion 304 in the fixing seat is at least partially located on the reinforcing rib 5, the matching portion 304 is separated from the reinforcing rib 5 by the first waterproofing membrane 1, and the plurality of dot-shaped matching portions 304 are connected by the transverse reinforcing rib 5, which can be used as a force point of the connection point to prevent the waterproofing membrane from being broken due to excessive stress.

[0034] like Figure 1-Figure 3 As shown, in one embodiment, the first waterproof coiled material 1 has two opposite first side walls, and the second waterproof coiled material 2 has two opposite second side walls. The two first side walls are connected to the two second side walls in a one-to-one correspondence, and the connection between the two protrudes outward to form a skirt 6. Specifically, in order to make the two adjacent protective devices close together and avoid water seepage after a gap is formed between them, this embodiment sets a skirt 6 at the connection between the two waterproof coiled materials. The skirt 6 adopts a single-layer waterproof coiled material and overlaps with the skirt 6 of another protective device, thereby improving the sealing of the two adjacent protective devices and avoiding leakage. Preferably, the skirt 6 is provided with a plurality of counterweights 7 to increase the weight of the skirt 6, so that it is close to the slope of the dam and closes the water seepage channel of the dam. In this embodiment, the counterweight 7 is an iron ring, and a plurality of iron rings are hung at the skirt 6 at intervals along the longitudinal direction. Of course, the counterweight 7 can also be other components that can increase the weight of the skirt 6, such as: steel balls.

[0035] A geotextile (not shown) is arranged outside the grouting cavity. The geotextile is arranged close to the second waterproofing coiled material 2 to isolate the flood embankment from the second waterproofing coiled material 2, to prevent the sharp protrusions at the flood embankment from piercing the second waterproofing coiled material 2, and to play a protective role.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
