The traditional bank protection structure is to lay concrete mortar bags and stones on the slopes to achieve the purpose of bank protection. This traditional bank protection method requires a large amount of concrete and natural stones, which is costly and has a long construction period. Moreover, this traditional bank protection method is not applicable to coastal areas and island reef areas that lack concrete and stones. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a coral mortar revetment structure based on a built-in grid-type mold bag.

[0004] The present invention is achieved through the following technical solutions:

[0005] A coral mortar bank protection structure based on a built-in grid-type mold bag, wherein a built-in grid-type mold bag is laid on a bank slope, and the inside of the built-in grid-type mold bag is filled with coral mortar; the top of the built-in grid-type mold bag extends to the top of the bank slope, and the bottom of the built-in grid-type mold bag extends to the bottom of the bank slope; a wave-blocking wall is arranged at the top of the bank slope, and the top of the built-in grid-type mold bag extends to the front position of the wave-blocking wall; a groove area is dug at the bottom of the bank slope, and the bottom of the built-in grid-type mold bag extends to the groove area, and blocks are laid in the groove area, and the bottom of the built-in grid-type mold bag is pressed in the blocks;

[0006] The built-in grid-type mold bag comprises a mold bag body, transverse reinforcing ribs, longitudinal reinforcing ribs, vertical reinforcing ribs and a grid. The transverse reinforcing ribs and longitudinal reinforcing ribs are arranged at equal intervals on the top surface of the mold bag body to form a grid array; the transverse reinforcing ribs and longitudinal reinforcing ribs are also arranged at equal intervals on the bottom surface of the mold bag body to form a grid array; the vertical reinforcing ribs are connected between the intersection points of the grid array on the top surface of the mold bag body and the intersection points of the grid array on the bottom surface of the mold bag body; the grid is arranged inside the mold bag body, and the grid is connected to the middle part of the vertical reinforcing ribs. When the mold bag body is poured with filling mortar, as the mold bag body is propped up, the grid is pulled up by the vertical reinforcing ribs. After the mold bag body is filled with mortar, the grid is at a middle height position inside the mold bag body, and acts as a reinforcing rib for the mortar inside the mold bag body.

[0007] In the above technical solution, a geotextile is also laid between the bank slope and the built-in grid-type mold bag.

[0008] In the above technical solution, the built-in grid-type mold bag can be conveniently shrunk into a roll before being filled with mortar, thereby facilitating transportation.

[0009] In the above technical solution, the number of grids in the mold bag body is one or more layers.

[0010] In the above technical solution, a filling port is provided on the top surface of the mold bag body of the built-in grid-type mold bag, which is used to fill coral mortar into the built-in grid-type mold bag.

Further, 1-3 layers of geotextiles 5 are laid between the bank slope and the built-in grid-type mold bag.

[0028] See the attached Figure 2 -Attached Figure 5 , specifically introduce the specific structure of the built-in grid type mold bag.

[0029] The built-in grid-type mold bag comprises a mold bag body 101, transverse reinforcement ribs (or "reinforcement warp") 102, longitudinal reinforcement ribs (or "reinforcement weft") 103, vertical reinforcement ribs (or "hanging ribs") 104 and a grid 105. The mold bag body 101 is bag-shaped, comprising a top surface, a bottom surface and surrounding covers. The transverse reinforcement ribs 102 and the longitudinal reinforcement ribs 103 are arranged at equal intervals on the top surface of the mold bag body 101 to form a grid array; the transverse reinforcement ribs 102 and the longitudinal reinforcement ribs 103 are also arranged at equal intervals on the bottom surface of the mold bag body 101. 2 and longitudinal reinforcement ribs 103 to form a grid array; the vertical reinforcement ribs 104 are connected between the intersection of the grid array on the top surface of the mold bag body 101 and the intersection of the grid array on the bottom surface of the mold bag body 101 (that is, one end of the vertical reinforcement rib 104 is connected to the intersection of the transverse reinforcement ribs 102 and the longitudinal reinforcement ribs 103 on the top surface of the mold bag body 101, and the other end of the vertical reinforcement rib 104 is connected to the intersection of the transverse reinforcement ribs 102 and the longitudinal reinforcement ribs 103 on the bottom surface of the mold bag body 101); the structure of the grid 105 is shown in the attached Figure 4 , which is a conventional product, the grid 105 is arranged inside the mold bag body 101, and the grid 105 is connected to the middle of the vertical reinforcement rib 104 through a connecting ring 106 (attached Figure 2 ), so that when the mortar is poured into the mold bag body 101, as the mold bag body 101 is propped up, the grille 105 is pulled up by the vertical reinforcing ribs 104. Finally, when the mold bag body 101 is filled with mortar, the grille 105 is at a middle height position in the mold bag body 101, thereby serving as a reinforcing rib for the mortar in the mold bag body 101.

[0030] It should be noted that the built-in grid-type mold bag can be easily shrunk into a roll before being filled with mortar (the grid is made of plastic and can be rolled up, so as not to affect the rolling of the entire built-in grid-type mold bag), so as to facilitate transportation. The built-in grid-type mold bag is prefabricated in the factory in advance, and in the rolled-up state, it is transported to the bank slope construction site, and then the built-in grid-type mold bag is unrolled and laid at the bank slope construction site, and then the filling mortar is poured into the mold bag body.

[0031] Furthermore, the number of the grids 105 in the mold bag body 10 is not limited to one layer, but can also be multiple layers. Figure 6 , can be two layers.

[0032] Furthermore, a filling port is provided on the top surface of the mold bag body 101 of the built-in grid-type mold bag 1 for filling the built-in grid-type mold bag 1 with coral mortar.

[0033] Preferably, see the attached Figure 5 Each 4*4 squares of the grid 105 corresponds to one square formed by the transverse reinforcement ribs 102 and the longitudinal reinforcement ribs 103 .

[0034] Preferably, the wave-breaking wall 2 is made of plain concrete or coral sand concrete.

[0035] Preferably, the block stone 4 is made of plain concrete or coral sand concrete.

[0036] Embodiment 2

[0037] The construction method of the coral mortar bank protection structure based on the built-in grid-type mold bag of the present invention is as follows:

[0038] Step 1: Level the slope of the bank slope. The slope ratio shall not be steeper than the designed slope. If the flatness does not meet the requirements, gravel or small sand bags can be laid for leveling.

[0039] Step 2: laying 1-3 layers of geotextile on the bank slope, constructing a wave-blocking wall 2 on the top of the bank slope, and digging a groove area 3 at the bottom of the bank slope.

[0040] Step 3, transport the prefabricated built-in grille mold bag 1 in a rolled-up state to the bank slope construction site, and then unroll and lay the built-in grille mold bag at the bank slope construction site; make the top of the built-in grille mold bag 1 extend to the front position of the wave-breaking wall 2, and the bottom of the built-in grille mold bag 1 extend to the groove area at the bottom of the bank slope.

[0041] Step 4, fill the built-in grid-type mold bag 1 with coral mortar. As the mold bag body 101 of the built-in grid-type mold bag is propped up, its built-in grid 105 is pulled up by the vertical reinforcement ribs 104. Finally, when the mold bag body 101 is filled with coral mortar, the grid 105 is at the middle height position in the mold bag body 101, thereby serving as a reinforcement rib for the coral sand in the mold bag body 101. Furthermore, the mold bag should be kept moist before filling, and the filling should be carried out from bottom to top, bin by bin. The pump tube and the filling port of the mold bag should be fastened. When the pump tube is inserted into the filling port, a shock-reducing baffle should be set at the pump tube port. The stress condition of the mold bag should be observed during the filling process. The filling flow rate should be (10-15) m 3 / h, the filling pressure should be (0.2~0.3)MPa.

[0042] Step 5, after the filling is completed, stones 4 are laid in the groove area at the bottom of the slope, so that the bottom of the built-in grid-type mold bag 1 is stably pressed in the stones 4.

[0043] The present invention is described above by way of example. It should be noted that, without departing from the core of the present invention, any simple deformation, modification or other equivalent replacement that can be made by those skilled in the art without inventive effort falls within the protection scope of the present invention.
