[0002] Bank protection is an engineering measure to artificially reinforce the existing coastal slopes to prevent the invasion and scouring of waves and currents and the action of groundwater, and to maintain the stability of the coastline. 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 construction method based on a coral mortar bank protection structure.

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

[0005] A construction method based on a coral mortar revetment structure comprises the following steps:

[0006] Step 1, leveling and sloping the bank slope;

[0007] Step 2: laying geotextile on the bank slope, constructing a wave-blocking wall on the top of the bank slope, and digging a groove area at the bottom of the bank slope;

[0008] Step 3, transporting the prefabricated built-in grid-type mold bag in a rolled-up state to the bank slope construction site, wherein the built-in grid-type mold bag comprises a mold bag body, transverse reinforcement ribs, longitudinal reinforcement ribs, vertical reinforcement ribs and a grid, wherein the transverse reinforcement ribs and longitudinal reinforcement ribs are evenly arranged on the top surface of the mold bag body to form a grid array; the transverse reinforcement ribs and longitudinal reinforcement ribs are also evenly arranged on the bottom surface of the mold bag body to form a grid array; the vertical reinforcement 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 reinforcement ribs;

[0009] Then, the built-in grid-type mold bag is unrolled and laid at the bank slope construction site, so that the top of the built-in grid-type mold bag extends to the front position of the wave-breaking wall, and the bottom of the built-in grid-type mold bag extends to the groove area at the bottom of the bank slope;

[0010] Step 4, filling the built-in grid-type mold bag with coral mortar, as the mold bag body of the built-in grid-type mold bag is propped up, the built-in grid is pulled up by the vertical reinforcement ribs, and after the mold bag body is filled with coral mortar, the grid is at the middle height position in the mold bag body, serving as a reinforcement rib for the coral sand in the mold bag body;

[0011] Step 5: After the filling is completed, stones are laid in the groove area at the bottom of the slope so that the bottom of the built-in grid-type mold bag is stably pressed in the stones.

[0012] In the above technical solution, a geotextile is also laid between the bank slope and the built-in grid-type mold bag.

[0013] 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.

[0014] In the above technical solution, the number of grids in the mold bag body is one or more layers.

[0015] 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.

[0016] In the above technical solution, each 4*4 squares of the grid corresponds to one square formed by the transverse reinforcement ribs and the longitudinal reinforcement ribs.

[0017] In the above technical solution, the wave-breaking wall is made of plain concrete or coral sand concrete.

[0018] In the above technical solution, the blocks are made of plain concrete or coral sand concrete.

[0019] The advantages and beneficial effects of the present invention are:

[0020] 1. The present invention designs a special built-in grid-type mold bag structure, lays the built-in grid-type mold bag on the bank slope, and fills the built-in grid-type mold bag with coral mortar. This method saves a lot of concrete and stone materials, and makes full use of the rich local coral sand resources on the coast, which is lower in cost. Since the built-in grid-type mold bag of the present invention is embedded with a plastic grid, and the mold bag itself has transverse reinforcement ribs, longitudinal reinforcement ribs and vertical reinforcement ribs for reinforcement, the filled coral sand can be stably placed in the built-in grid-type mold bag to form a stable bank protection structure.

[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with specific embodiments.

[0034] The present invention designs a construction method based on coral mortar bank protection structure, see attached Figure 1 , the specific construction steps are as follows:

[0035] 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.

[0036] Step 2, see attached Figure 2 , 1-3 layers of geotextile 1 are laid on the bank slope, and a wave retaining wall 2 is constructed on the top of the bank slope, and a groove area 3 is dug at the bottom of the bank slope. Preferably, the wave retaining wall 2 is made of plain concrete or coral sand concrete.

[0037] Step 3, see attached Figure 3 The prefabricated built-in grille mold bag 4 is transported to the bank slope construction site in a rolled-up state, and then the built-in grille mold bag is unrolled and laid at the bank slope construction site, so that the top of the built-in grille mold bag 4 extends to the front position of the wave-breaking wall 2, and the bottom of the built-in grille mold bag 4 extends to the groove area at the bottom of the bank slope.

[0038] See the attached Figure 6 -Attached Fig.10 , the specific structure of the built-in grid-type mold bag 4 is specifically introduced.

[0039] The built-in grid-type mold bag 4 includes a mold bag body 401, transverse reinforcement ribs (or "reinforcement warp") 402, longitudinal reinforcement ribs (or "reinforcement weft") 403, vertical reinforcement ribs (or "hanging ribs") 404 and a grid 405. The mold bag body 401 is bag-shaped, including a top surface, a bottom surface and four surrounding covers. The transverse reinforcement ribs 402 and the longitudinal reinforcement ribs 403 are evenly arranged on the top surface of the mold bag body 401 to form a grid array; the transverse reinforcement ribs 402 and the longitudinal reinforcement ribs 403 are also evenly arranged on the bottom surface of the mold bag body 401. 02 and longitudinal reinforcement ribs 403 to form a grid array; the vertical reinforcement ribs 404 are connected between the intersection of the grid array on the top surface of the mold bag body 401 and the intersection of the grid array on the bottom surface of the mold bag body 401 (that is, one end of the vertical reinforcement rib 404 is connected to the intersection of the transverse reinforcement ribs 402 and the longitudinal reinforcement ribs 403 on the top surface of the mold bag body 401, and the other end of the vertical reinforcement rib 404 is connected to the intersection of the transverse reinforcement ribs 402 and the longitudinal reinforcement ribs 403 on the bottom surface of the mold bag body 401); the structure of the grid 405 can be found in the attached Figure 8 , which is a conventional product, the grille 405 is arranged inside the mold bag body 401, and the grille 405 is connected to the middle of the vertical reinforcement rib 404 through a connecting ring 406 (attached Figure 6), so that when the mold bag body 401 is filled with mortar, as the mold bag body 401 is propped up, the grille 405 is pulled up by the vertical reinforcing ribs 404. Finally, when the mold bag body 401 is filled with mortar, the grille 405 is at a middle height position in the mold bag body 401, thereby serving as a reinforcing rib for the mortar in the mold bag body 401.

[0040] 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 transported to the bank slope construction site in a rolled-up state, and then the built-in grid-type mold bag is unrolled and laid at the bank slope construction site.

[0041] Furthermore, the number of the grids 405 in the mold bag body 401 is not limited to one layer, but may be multiple layers. Fig.10 The top surface of the mold bag body 401 of the built-in grid-type mold bag 4 is provided with a filling port for filling the built-in grid-type mold bag 4 with coral mortar. Fig. 9 Each 4*4 squares of the grid 405 corresponds to one square formed by the transverse reinforcement ribs 402 and the longitudinal reinforcement ribs 403 .

[0042] Step 4, see attached Figure 4 , coral mortar is filled into the built-in grid-type mold bag 4. As the mold bag body 401 of the built-in grid-type mold bag is propped up, its built-in grid 405 is pulled up by the vertical reinforcement ribs 404. Finally, when the mold bag body 401 is filled with coral mortar, the grid 405 is at the middle height position in the mold bag body 401, thereby serving as a reinforcement rib for the coral sand in the mold bag body 401.

[0043] Furthermore, the mold bag should be kept moist before filling, and the filling should be carried out from bottom to top, one compartment at a time. The pump tube and the filling port of the mold bag should be tied tightly. When the pump tube is inserted into the filling port, a shock-reducing baffle should be installed at the pump tube port. The force 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.

[0044] Step 5: After filling, refer to the attached Figure 5 , block stones 5 are laid in the groove area at the bottom of the bank slope, so that the bottom of the built-in grid-type mold bag 4 is stably pressed in the block stones 5. Preferably, the block stones 5 are made of plain concrete or coral sand concrete.

[0045] 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.
