A construction method for a revetment structure using coral mortar combined with geocell construction.

Abstract

This invention discloses a construction method for a revetment structure using coral sand and geocells. It employs a unique built-in geocell-type geotextile bag structure, which is laid on the bank slope and filled with coral sand. This method eliminates the need for large amounts of concrete and stone, while fully utilizing the abundant local coral sand resources, resulting in lower costs. Because the built-in geotextile bag incorporates plastic cells and is reinforced with transverse, longitudinal, and vertical ribs, the filled coral sand remains stably within the geotextile bag, forming a stable revetment structure.

Description

Technical Field

[0001] This invention belongs to the field of bank protection technology, and in particular to a construction method for a bank protection structure using coral mortar combined with geocell construction. Background Technology

[0002] Shore protection is an engineering measure that artificially reinforces existing coastal slopes to protect against wave and current erosion, as well as groundwater action, thus maintaining shoreline stability. Traditional shore protection structures involve laying concrete mortar bags and stones on the slope to achieve this purpose. This traditional method requires large quantities of concrete and natural stone, resulting in high costs and long construction periods. Furthermore, it is unsuitable for coastal areas and island / reef regions lacking concrete and stone resources. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a construction method for a revetment structure using coral mortar combined with geocell construction.

[0004] This invention is achieved through the following technical solution:

[0005] A construction method for a revetment structure using coral mortar combined with geocell construction includes the following steps:

[0006] Step 1: Level and smooth the slope surface of the bank.

[0007] Step 2: Lay geotextile on the bank slope, construct a wave-breaking wall at the top of the bank slope, and excavate a groove area at the bottom of the bank slope.

[0008] Step 3: Lay the built-in grid-type membrane bags on the bank slope, so that the top of the built-in grid-type membrane bags extends to the front edge of the wave-breaking wall and the bottom of the built-in grid-type membrane bags extends to the groove area at the bottom of the bank slope.

[0009] The built-in compartmentalized molded bag includes a molded bag body, horizontal reinforcing ribs, vertical reinforcing ribs, and compartments. The molded bag body is bag-shaped, including a top surface, a bottom surface, and four side covers. Horizontal and vertical reinforcing ribs are arranged at equal intervals on the top surface of the molded bag body to form a grid array. Horizontal and vertical reinforcing ribs are also arranged at equal intervals on the bottom surface of the molded bag body to form a grid array. The vertical reinforcing ribs connect the intersections of the grid arrays on the top surface and the bottom surface of the molded bag body. The compartments are located inside the molded bag body.

[0010] Step 4: Fill the built-in cellar molded bags with coral mortar;

[0011] Step 5: After filling, lay boulders in the grooved area at the bottom of the bank slope so that the bottom of the built-in cell-type mold bag is stably pressed into the boulders.

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

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

[0014] In the above technical solution, the mold bag should be kept moist before filling. During filling, it should be carried out from bottom to top, compartment by compartment. When the pump pipe is inserted into the filling port, it is advisable to install a baffle to reduce the impact at the pump pipe port.

[0015] In the above technical solution, the irrigation flow rate is (10-15) m³ / s. 3 / h, filling pressure is (0.2~0.3)MPa.

[0016] In the above technical solution, the top surface of the inner cell mold bag body is provided with an filling port for filling the inner cell mold bag with coral mortar.

[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 stone blocks are made of plain concrete or coral sand concrete.

[0019] The advantages and beneficial effects of this invention are as follows:

[0020] This invention presents a construction method for a revetment structure using coral sand and geocells. It employs a unique built-in geocell-type geotextile bag structure, which is laid on the bank slope and filled with coral sand. This method eliminates the need for large amounts of concrete and stone, while fully utilizing the abundant local coral sand resources, resulting in lower costs. Because the built-in geotextile bags of this invention have embedded plastic cells and are reinforced with transverse, longitudinal, and vertical ribs, the filled coral sand remains stably within the geotextile bags, forming a stable revetment structure.

The bag body 101 is bag-shaped, including a top surface, a bottom surface, and four side covers. Transverse reinforcing ribs 102 and longitudinal reinforcing ribs 103 are arranged at equal intervals on the top surface of the bag body 101, forming a grid array; transverse reinforcing ribs 104 are also arranged at equal intervals on the bottom surface of the bag body 101. 2 and longitudinal reinforcing ribs 103 form a grid array; the vertical reinforcing ribs 104 are connected between the intersection of the grid array on the top surface of the molded bag body 101 and the intersection of the grid array on the bottom surface of the molded bag body 101 (that is, one end of the vertical reinforcing rib 104 is connected to the intersection of the transverse reinforcing ribs 102 and the longitudinal reinforcing ribs 103 on the top surface of the molded bag body 101, and the other end of the vertical reinforcing rib 104 is connected to the intersection of the transverse reinforcing ribs 102 and the longitudinal reinforcing ribs 103 on the bottom surface of the molded bag body 101); the structure of the grid 105 is shown in the appendix. Figure 4 As a conventional product, the cell 105 is located inside the mold bag body 101, which serves to reinforce the mortar inside the mold bag body 101.

[0033] Furthermore, the top surface of the mold bag body 101 of the built-in cell mold bag 1 is provided with an filling port for filling the built-in cell 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 stone block 4 is made of plain concrete or coral sand concrete.

[0036] The construction method of the above-mentioned revetment structure of the present invention is as follows:

[0037] Step 1: Level and smooth the slope surface of the bank slope. The slope ratio must not be steeper than the designed slope. If the flatness does not meet the requirements, gravel or small sandbags can be laid to level it.

[0038] Step 2: Lay 1-3 layers of geotextile on the bank slope, construct a wave-breaking wall 2 at the top of the bank slope, and excavate a groove area 3 at the bottom of the bank slope.

[0039] Step 3: Lay the built-in grid-type membrane bags on the bank slope, so that the top of the built-in grid-type membrane bags 1 extends to the front edge of the wave-breaking wall 2, and the bottom of the built-in grid-type membrane bags 1 extends to the groove area at the bottom of the bank slope.

[0040] Furthermore, when laying the built-in compartment type molded bag, firstly, the bottom surface of the molded bag body 101 is laid, then the compartments 105 are laid on the bottom surface of the molded bag body 101, and then the top surface of the molded bag body 101 is laid, so that the compartments 105 are sandwiched between the top and bottom surfaces of the molded bag body 101; then, the top and bottom surfaces of the molded bag body 101 are connected to form a four-sided cover, and the top and bottom surfaces are connected by vertical reinforcing ribs 104 (that is, one end of the vertical reinforcing rib 104 is connected to the intersection of the horizontal reinforcing rib 102 and the longitudinal reinforcing rib 103 on the top surface of the molded bag body 101, and the other end of the vertical reinforcing rib 104 is connected to the intersection of the horizontal reinforcing rib 102 and the longitudinal reinforcing rib 103 on the bottom surface of the molded bag body 101), thereby constructing the built-in compartment type molded bag.

[0041] Furthermore, since there will be water at the bottom of the bank slope, it is necessary to first lay and construct the built-in grid-type mold bag 1 in the waterless area of ​​the bank surface, and then move the constructed built-in grid-type mold bag 1 down as a whole, so that the bottom of the built-in grid-type mold bag 1 moves to the groove area at the bottom of the bank slope.

Filling should proceed from bottom to top, compartment by compartment. The pump pipe should be securely fastened to the filling port of the formwork bag. When the pump pipe is inserted into the filling port, a pressure-reducing baffle should be installed at the pump pipe inlet. The stress on the formwork bag should be observed during filling. The filling flow rate should be (10-15) m³ / s. 3 The filling pressure should be (0.2~0.3) MPa per hour.

[0043] Step 5: After filling is completed, lay stones 4 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 into the stones 4.
