This traditional bank protection method needs to use a large amount of concrete and natural stone, has a high cost, and has a long construction period. Moreover, this traditional bank protection method is not suitable for coast areas and island reef areas that lack concrete and stone. SUMMARY

[0026] A coral mortar revetment structure based on an embedded grid type mold bag, referring to the accompanying drawings, Figure 1 An embedded grid type mold bag 1 is laid on the bank slope, and the embedded grid type mold bag is filled with coral mortar inside.

[0027] The top of the embedded grid type mold bag 1 extends to the top of the bank slope, and the bottom of the embedded grid type mold bag extends to the bottom of the bank slope; further, a wave retaining wall 2 is arranged at the top of the bank slope, the top of the embedded grid type mold bag 1 extends to the front position of the wave retaining wall 2, a groove area 3 is excavated at the bottom of the bank slope, the bottom of the embedded grid type mold bag 1 extends to the groove area 3, and block stones 4 are laid in the groove area, and the bottom of the embedded grid type mold bag 1 is stably pressed in the block stones 4. Further, 1-3 layers of geotextiles 5 are laid between the bank slope and the embedded grid type mold bag.

[0028] Referring to the accompanying drawings, Figure 2 - the accompanying drawings, Figure 5 , the specific structure of the embedded grid type mold bag is specifically introduced.

[0029] The built-in grid type mold bag includes a mold bag body 101, a transverse reinforcing rib (or "reinforcing warp") 102, a longitudinal reinforcing rib (or "reinforcing weft") 103, a vertical reinforcing rib (or "hanging rib") 104, and a grid 105. The mold bag body 101 is bag-shaped and includes a top surface, a bottom surface, and a peripheral sealing surface. The transverse reinforcing ribs 102 and the longitudinal reinforcing ribs 103 are arranged at equal intervals on the top surface of the mold bag body 101 to form a square grid array. The transverse reinforcing ribs 102 and the longitudinal reinforcing ribs 103 are also arranged at equal intervals on the bottom surface of the mold bag body 101 to form a square grid array. The vertical reinforcing rib 104 is connected between the intersection points of the square grid array on the top surface of the mold bag body 101 and the intersection points of the square grid array on the bottom surface of the mold bag body 101 (i.e., one end of the vertical reinforcing rib 104 is connected to the intersection point of the transverse reinforcing rib 102 and the longitudinal reinforcing rib 103 on the top surface of the mold bag body 101, and the other end of the vertical reinforcing rib 104 is connected to the intersection point of the transverse reinforcing rib 102 and the longitudinal reinforcing rib 103 on the bottom surface of the mold bag body 101). The structure of the grid 105 is shown in the accompanying drawings. Figure 4 The grid 105 is arranged inside the mold bag body 101, and the middle part of the grid 105 is connected to the vertical reinforcing rib 104 through a connecting ring 106 (see the accompanying drawings). Figure 2 In this way, when the mold bag body 101 is filled with mortar, the grid 105 is pulled up by the vertical reinforcing rib 104 as the mold bag body 101 is lifted. Finally, when the mold bag body 101 is filled with mortar, the grid 105 is at a middle height position inside the mold bag body 101, thereby playing a role of 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 conveniently rolled up before being filled with mortar (the grid is made of plastic material and can be rolled up, thereby not affecting the rolling of the entire built-in grid type mold bag), thereby facilitating transportation. The built-in grid type mold bag is prefabricated in a factory, transported to a slope construction site in a rolled state, laid out on the slope construction site, and then filled with mortar.

[0031] Further, the number of grids 105 in the mold bag body 101 is not limited to one layer, but can also be multiple layers, for example, referring to the accompanying drawings. Figure 6 There can be two layers.

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

[0033] Preferably, referring to the accompanying drawings, Figure 5 Each 4*4 square grid of the grid 105 corresponds to one square grid formed by the transverse reinforcing rib 102 and the longitudinal reinforcing rib 103.

[0034] Preferably, the wave retaining 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 Two

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

[0038] Step 1, the slope surface of the bank slope is leveled and graded, and the slope ratio should not be steeper than the design slope; when the flatness does not meet the requirements, gravel or small sand bags can be laid to level.

[0039] Step 2, 1-3 layers of geotextile are laid on the bank slope, and a wave retaining wall 2 is constructed at the top of the bank slope, and a groove area 3 is excavated at the bottom of the bank slope.

[0040] Step 3, the built-in grid type mold bag 1 is transported to the bank slope construction site in a rolled state, and then the built-in grid type mold bag is laid in the bank slope construction site; the top of the built-in grid type mold bag 1 extends to the front position of the wave retaining wall 2, and the bottom of the built-in grid type mold bag 1 extends 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 sand mortar, as the mold bag body 101 of the built-in grid type mold bag is lifted, the built-in grid 105 is pulled up by the vertical reinforcing rib 104, and finally, when the mold bag body 101 is filled with coral sand mortar, the grid 105 is at the middle height position in the mold bag body 101, thereby playing the role of reinforcing rib for the coral sand in the mold bag body 101. Further, the mold bag should be kept moist before filling, the filling should be carried out from bottom to top in turn, the pump pipe should be firmly connected with the filling port of the mold bag, a shock-reducing baffle should be arranged at the pump pipe port when the pump pipe is inserted into the filling port, and the stress condition of the mold bag should be observed during the filling process. The filling flow rate is preferably (10-15) m 3 / h, and the filling pressure is preferably (0.2-0.3) MPa.

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

[0043] The above has exemplarily described the present application, and it should be noted that any simple modification, change or other equivalent replacement which does not deviate from the core of the present application and can be made by those skilled in the art without creative labor falls within the protection scope of the present application.
