[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 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 shortcomings of the prior art and provide a construction method for constructing a bank protection structure using coral mortar combined with geocells.

[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, laying a built-in cell-type mold bag on the bank slope, so that the top of the built-in cell-type mold bag extends to the front position of the wave-breaking wall, and the bottom of the built-in cell-type mold bag extends to the groove area at the bottom of the bank slope;

[0009] The built-in cell-type mold bag includes a mold bag body, transverse reinforcement ribs, longitudinal reinforcement ribs, vertical reinforcement ribs and cells. The mold bag body is bag-shaped, including a top surface, a bottom surface and four surrounding covers. 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 cells are arranged inside the mold bag body.

[0010] Step 4, filling the built-in cell-type mold bag with coral mortar;

[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 cell-type mold bag is stably pressed in the stones.

[0012] In the above technical solution, in step 3, when laying the built-in cell-type mold bag, first lay the bottom surface of the mold bag body, then lay the cells on the bottom surface of the mold bag body, and then lay the top surface of the mold bag body, so that the cells are sandwiched between the top and bottom surfaces of the mold bag body; then connect the top and bottom surfaces of the mold bag body around to form a surrounding cover, and connect the top and bottom surfaces through vertical reinforcement ribs, thereby constructing the built-in cell-type mold bag.

[0013] In the above technical solution, in step 3, it is necessary to first lay and construct the built-in cell-type mold bag in the waterless shore area, and then move the constructed built-in cell-type mold bag downward as a whole so that the bottom of the built-in cell-type mold bag is moved to the groove area at the bottom of the slope.

[0014] In the above technical solution, the mold bag is kept moist before filling, and the filling should be carried out from bottom to top, compartment by compartment. When the pump tube is inserted into the filling port, a shock-reducing baffle should be set at the pump tube port.

[0015] In the above technical solution, the filling flow rate is (10~15)m 3 / h, the filling pressure is (0.2~0.3)MPa.

[0016] In the above technical solution, a filling port is provided on the top surface of the mold bag body of the built-in cell-type mold bag, which is used to fill the coral mortar into the built-in cell-type mold bag.

[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] The construction method of the present invention adopts coral mortar combined with geocell to construct a revetment structure, designs a special built-in cell-type mold bag structure, lays the built-in cell-type mold bag on the bank slope, and fills the built-in cell-type mold bag with coral mortar, which saves a lot of concrete and stone, and makes full use of the rich local coral sand resources on the coast, with lower cost. Since the built-in cell-type mold bag of the present invention has plastic cells embedded in it, and the mold bag itself has transverse reinforcement bars, longitudinal reinforcement bars and vertical reinforcement bars for reinforcement, the filled coral sand can be stably placed in the built-in cell-type mold bag to form a stable revetment structure.

The cell 105 is arranged inside the mold bag body 101, and plays the role of reinforcing ribs for the mortar in the mold bag body 101.

[0033] Furthermore, a filling port is provided on the top surface of the mold bag body 101 of the built-in cell-type mold bag 1 for filling the built-in cell-type mold bag 1 with coral mortar.

[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] The construction method of the above-mentioned bank protection structure of the present invention is as follows:

[0037] 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.

[0038] 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.
