Description

Technical Field

[0001] The present invention belongs to the technical field of dredger fill solidification, and relates to a rapid solidification device for dredger fill used in offshore land reclamation. Background Art

[0002] Offshore land reclamation is an effective way to expand land resources. A large amount of dredged soil or soil from other sources generated in projects such as dredging channels and port construction is deposited in the offshore shallow beach area by means of hydraulic filling. After a series of treatments, it forms land that can be developed and utilized, providing valuable land resources for urban construction, industrial development, port expansion, etc.

[0003] During the solidification process of dredger fill, first, the dredger fill is preliminarily filtered to remove large particles and impurities such as shells inside the dredger fill. The selected solidifying agent is added to the filtered dredger fill according to a certain ratio, and then fully and evenly mixed by means of mechanical stirring, etc. The reaction between the solidifying agent and the dredger fill will produce gel. Under the cementing and filling effects of the gel and chemical reaction products, the soil particles inside the fill form a relatively stable structure. At this time, the dredger fill is no longer prone to large-scale movement or redispersion of particles, and the stability of its overall structure is better guaranteed.

[0004] In actual engineering applications, the sources of dredger fill are extensive, and it is difficult to completely and accurately control its soil composition. There is often a situation where the salt content inside the dredger fill is high. When treating such dredger fill with high salt content soil by the conventional method of continuously adding solidifying agent, the chemical components in the solidifying agent (for example, a large amount of calcium ions in the cement solidifying agent) will chemically react with the salt in the high salt content dredger fill, and then calcium salt precipitate hard lumps will be generated, causing the calcium ions to react rapidly with the components in the high salt content soil to form a large amount of precipitate. The formation of these large amounts of precipitate will form an uneven solidification structure inside the dredger fill, seriously affecting the solidification effect and resulting in the inability of the solidified dredger fill to meet the expected engineering performance requirements. Summary of the Invention

[0005] Object of the Invention: The object of the present invention is to provide a rapid solidification device for dredger fill used in offshore land reclamation to solve the problems that it is difficult to completely and accurately control the soil composition of dredger fill, and when the salt content inside the dredger fill is high, the chemical components in the solidifying agent will chemically react with the salt in the high salt content dredger fill, seriously affecting the solidification effect.

The power supply system is controlled by the rotation state of the impeller to energize the electromagnet. The position of the magnet block is controlled by the on-off state of the electromagnet, so as to control the positions of the first gear and the second gear, so that the first gear meshes with the third gear or the second gear meshes with the residual gear.

[0010] Further, a sensor is arranged on the impeller. The sensor senses the rotation state of the impeller to form an electrical signal and sends it to the power supply system. The power supply system controls the electromagnet to be energized.

[0017] Further, the curing device further includes an energy storage device and its control system, and the electric energy generated by the generator is stored by the energy storage device for use in electrical appliances.

[0018] Working principle: Regarding the salts in the soil: In offshore land reclamation projects, the dredged soil is mostly taken from the seaside. Such soil usually has a high salt content. The common salts in the soil include sodium chloride (NaCl), magnesium chloride (MgCl2), sodium sulfate (Na2SO4), etc. These salts are prone to chemical reactions when they encounter calcium ions in the curing agent.

[0019] During the solidification process, if the curing agent is continuously added in a conventional manner, the chemical components in the curing agent (such as calcium ions in the cement curing agent) will react chemically with the salts in the highly saline dredger fill soil, generating calcium salt precipitate hard lumps and forming an uneven solidification structure. When the salt content inside the dredger fill soil is relatively high, at this time, the curing agent reacts with the highly saline soil to produce calcium salt precipitate hard lumps. The relatively large mass of the calcium salt precipitate hard lumps will accumulate above the partition net at the bottom of the main box. Multiple accumulated calcium salt precipitate hard lumps will block the partition net. Only when the salt content of the dredger fill soil is relatively high can it react quickly with the curing agent to produce relatively large precipitate hard lumps and block the partition net. When the internal salt content is low or there is no salt, no precipitate lumps are produced or the produced precipitate lumps are relatively small. The relatively small particles will not block the partition net and do not affect the overall solidification effect of the dredger fill soil. The blocked partition net makes it impossible for the dredger fill soil to enter the spiral conveyor through the connecting pipe. At this time, the discharge hopper does not discharge the dredger fill soil inside. After losing the driving force of the dredger fill soil flow, the impeller cannot continue to rotate, the power supply system does not supply power, the electromagnet loses power supply, so that the electromagnet loses magnetic force. There is no longer a repulsive force between the electromagnet and the magnet block. And the inside of the electromagnet is an iron core. At this time, the magnet block can attract the iron core inside the electromagnet to automatically identify the high or low salt content.

[0020] Advantages: Compared with the prior art, the present invention has the following remarkable advantages: 1. The rapid solidification equipment for dredger fill soil used in offshore land reclamation circulates and conveys the dredger fill soil between the main box and the discharge hopper through a spiral conveyor. At the same time, it uses the flow of the dredger fill soil in the discharge hopper to drive the impeller to rotate and generate electricity, and then controls the curing agent feeding assembly to achieve continuous feeding of the curing agent, which is conveyed back to the main box synchronously with the dredger fill soil, and cooperates with the rotating cylinder in the main box to drive the stirring rod to stir, greatly improving the stirring and mixing efficiency and effect.

[0021] 2. The rapid solidification equipment for dredger fill soil used in offshore land reclamation can automatically judge whether the dredger fill soil contains highly saline soil inside. When it does not contain highly saline soil, the curing agent is continuously added to improve the solidification efficiency; when it contains highly saline soil, it automatically switches to the method of adding in multiple small amounts, which can, to a certain extent, avoid the problem that a large amount of precipitate is generated due to the too high salt content inside the dredger fill soil and the rapid reaction of the curing agent.

[0022] 3. The rapid solidification equipment for dredger fill soil used in offshore land reclamation, when the partition net is blocked by calcium salt precipitate hard lumps, can not only automatically switch the curing agent feeding method, but also, through the linkage of the generator and the solenoid valve, when hard lumps appear, make the external complexing agent enter the rotating cylinder, use the complexing agent to remove the already generated calcium salt precipitate hard lumps, and prevent subsequent hard lumps from being generated, ensuring the correct solidification of the dredger fill soil and avoiding the problem of a large amount of precipitate when highly saline soil is solidified.

[0036] The left side of the discharge hopper 7 is located at the top of the main body box 1. The discharge hopper 7 is internally connected to the screw conveyor 5, and both ends of the connecting pipe 6 are respectively connected to the inside of the main body box 1 and the screw conveyor 5.

A stirring rod is fixedly installed on the outer side of the rotating cylinder 44. The inside of the rotating cylinder 44 is hollow, and the bottom of the rotating cylinder 44 is located above the partition net 8. An electromagnet 320 is fixedly installed on the top of the cross plate 34 and at the back of the magnet block 318. A side plate 322 is fixedly installed on the top of the cross plate 34. A spring 321 is fixedly installed between the side plate 322 and the front of the magnet block 318.

[0037] In this embodiment, when the blown fill is solidified, the blown fill is placed inside the main box 1, and the curing agent enters the delivery box 31 through the feed pipe 32. By starting the screw conveyor 5, the blown fill inside the main box 1 can be transported to the inside of the screw conveyor 5 through the connecting pipe 6. The blown fill is soil with a high water content in the initial state. When the blown fill is completely solidified, the shape is similar to gravel. Both states can be transported by the screw conveyor 5 without causing the blown fill to be blocked inside the screw conveyor 5. When the blown fill passes through the discharge bucket 7 and is discharged back into the main box 1, the blown fill passes through the discharge bucket 7 under the influence of its own gravity and the push generated by the screw conveyor 5. Under the action of force, the blown fill soil quickly passes through the discharge bucket 7, and the fast-flowing blown fill soil can move the impeller 22, and the rotation of the impeller 22 can drive the generator 23 to rotate, and the rotation of the generator 23 can generate electricity (the power of the screw conveyor 5 is constant when it is running, and the speed of the blown fill soil flowing remains basically unchanged. The power generated by the generator 23 tends to be stable. The generator 23 has two states: no power generation and power generation). After the power is generated, the generated power supplies power to the electromagnet 320 and the electromagnetic valve 47. The electromagnet 320 generates magnetic force after being energized, and the screw conveyor 5 stably transports the blown fill soil, which can ensure the stable rotation of the impeller 22 and the stable The rotating impeller 22 keeps the generator 23 generating electricity stably. The stable current can ensure that the electromagnet 320 generates a stable magnetic force. The magnetic force generated by the electromagnet 320 and the magnetic force between the magnet block 318 generate a repulsive force under the mutual repulsion of the same magnetic poles. The repulsive force and the elastic force between the spring 321 are balanced within a certain range. At this time, the position of the magnet block 318 and the upper vertical plate 317 just ensures that the first gear 313 and the third gear 315 can mesh within a certain range, ensuring that the first gear 313 and the third gear 315 can mesh normally. At this time, the first motor 35 rotates through the third gear 315 , the first gear 313, the cross rotating rod 311, the back rod 310, and the rotating rod 38 drive the partition 39 to rotate. The partition 39 continuously rotates to ensure that the curing agent entering between the partitions 39 through the feeding pipe 32 can be continuously discharged through the delivery port 37. The curing agent discharged through the delivery port 37 falls into the discharge bucket 7 below. The continuous delivery of the curing agent cooperates with the continuous delivery of the blown fill soil in the discharge bucket 7, and the mixture of the two can be synchronously delivered to the main box 1. At this time, the internal rotating cylinder 44 drives the outer stirring rod to stir and mix the internal curing agent and the blown fill soil, which can improve the stirring and mixing efficiency and mixing effect;

[0038] When the salt content inside the dredger fill is low or salt - free, rapid solidification of the dredger fill can be achieved through continuous mixing of the curing agent. When the salt content inside the dredger fill is high, at this time, the reaction between the curing agent and the high - salt - content soil will produce calcium salt precipitation hard lumps. The relatively large mass of the calcium salt precipitation hard lumps will accumulate above the partition net 8 at the bottom of the main box 1. Multiple accumulated calcium salt precipitation hard lumps will block the partition net 8. Only when the salt content of the dredger fill is high can it react quickly with the curing agent to produce precipitation hard lumps with a larger volume and block the partition net 8. When the internal salt content is low or salt - free, no precipitation lumps are produced or the produced precipitation lumps are small in size. The small particles will not block the partition net 8 and do not affect the overall solidification effect of the dredger fill. The blockage of the partition net 8 causes the dredger fill to be unable to enter the screw conveyor 5 through the connecting pipe 6. At this time, the discharge hopper 7 does not discharge the dredger fill inside. After losing the driving force of the dredger fill flow, the impeller 22 cannot continue to rotate, the generator 23 stops generating electricity, and the electromagnet 320 loses power supply, so that the electromagnet 320 loses its magnetic force. There is no longer a repulsive force between the electromagnet 320 and the magnet block 318. And the electromagnet 320 has an iron core inside. At this time, the magnet block 318 can attract the iron core inside the electromagnet 320, so that the magnet block 318 approaches and adsorbs on the electromagnet 320. The magnet block 318 has a large magnetic force. When the electromagnet 320 is powered off, the attractive force between the magnet block 318 and the iron core of the electromagnet 320 is large. And the cross - turning rod 311 and the back rod 310 are connected by means of a ball connection, and the friction between the two is small, so as to ensure that the magnet block 318 has enough force to move. The sliding of the magnet block 318 will drive the upper vertical plate 317 to move synchronously. At this time, the first gear 313 disengages from the third gear 315, and the second gear 314 meshes with the residual gear 316. And the design of the cross - turning rod 311 and the back rod 310 ensures that the rotating shaft 312 can move back and forth without affecting the transmission between the two. The residual gear 316 is driven to rotate by the first motor 35. In the initial state, the residual gear 316 is in an idling state. The rotation speed of the first motor 35 is low and will not generate too much eccentric force, which does not affect the overall rotation stability. The intermittent movement of the second gear 314 can be realized through the residual gear 316. The intermittent movement of the rotating rod 38 and the partition plate 39 is realized through the intermittent movement of the second gear 314. Through the intermittent rotation of the partition plate 39, the curing agent between the two partition plates 39 can be put into the main box 1 at regular intervals. When the salt content inside the dredger fill is high, the curing agent is switched to multiple small - amount additions. Add it multiple times and fully stir it with the stirring rod each time to make the curing agent react preliminarily with the dredger fill, and then add the next batch. This can, to a certain extent, avoid the problem of too high local calcium ion concentration caused by a large - amount one - time addition of the curing agent, and further avoid the problem of rapid reaction to generate a large amount of precipitation;

[0039] Regarding the power-on issues of generators and electromagnets, in the present invention, an energy storage device and related control systems (inverters and discharge systems) can be set up. The electricity generated by the generator is stored in the energy storage device for use by devices such as electromagnets, solenoid valves, or other low-power equipment. Secondly, the generator can also be abandoned and power supplied from the power grid. At this time, sensors are set on the impeller 22. The rotation and non-rotation of the impeller 22 are sensed by the sensors (the rotation situation of the impeller 22 can be judged by comparing the rotation amplitude with a preset threshold), and electrical signals are formed and sent to the discharge system (which contains a corresponding PLC or controller). The electromagnet is controlled to be powered on through the discharge system, and the remaining process is the same as above.

[0040] According to the above content, it is possible to automatically judge the salt content in the dredger fill and automatically switch the dosing method of the curing agent: when the salt content in the dredger fill is low or salt-free, the curing agent is continuously added. The method of continuously adding the curing agent is more efficient. When the salt content in the dredger fill is high, the method of adding in small amounts multiple times is adopted, which can effectively avoid the formation of a large amount of precipitation.

[0041] Refer to Figures 1 to 8 , in one aspect of this embodiment, a communication box 42 is fixedly installed at the top of the support frame 41. A second motor 43 is fixedly installed at the top of the communication box 42. The top of the rotating cylinder 44 movably penetrates the inside of the support frame 41 and the communication box 42. The output end of the second motor 43 movably penetrates the top wall of the communication box 42. The top of the rotating cylinder 44 is fixedly installed at the bottom of the output end of the second motor 43. A communication groove 45 is formed in the side wall of the rotating cylinder 44. The communication groove 45 communicates the inside of the rotating cylinder 44 with the inside of the communication box 42. A feeding pipe 46 is fixedly installed on the side wall of the communication box 42. A solenoid valve 47 is fixedly installed at the connection between the feeding pipe 46 and the communication box 42. The solenoid valve 47 is electrically connected to the generator 23 through an inverter. The solenoid valve 47 is a normally open solenoid valve. When the solenoid valve 47 is not powered on, the valve is in an open state, and the fluid can pass freely.

[0042] In this embodiment, when the rotating cylinder 44 rotates, the second motor 43 drives the rotation of the rotating cylinder 44. When the discharge hopper 7 discharges the dredger fill normally, the generator 23 generates electricity. At this time, the solenoid valve 47 is energized, and the energized solenoid valve 47 is in a closed state. The complexing agent in the external complexing agent storage container is transported through the feeding pipe 46. The complexing agent is a liquid, and the complexing agent introduced into the inside of the feeding pipe 46 is blocked by the solenoid valve 47 and cannot enter the inside of the communication box 42. When the generator 23 stops generating electricity, it indicates that calcium salt precipitate hard blocks have been generated. At this time, the solenoid valve 47 is de-energized, and the de-energized solenoid valve 47 is in a communicating state. The external complexing agent enters the inside of the communication box 42 through the feeding pipe 46, and the complexing agent is introduced into the inside of the rotating cylinder 44 through the communication groove 45. The complexing agent is introduced into the calcium salt precipitate hard blocks accumulated on the lower partition net 8 through the rotating cylinder 44. The complexing agent can prevent calcium ions from combining with other anions to form precipitates. Because the complexing agent has a strong binding ability with calcium ions, it will preferentially combine with calcium ions to make the calcium ions in a relatively stable complex state, thereby removing the already generated calcium salt precipitate hard blocks and preventing the generation of subsequent calcium salt precipitate hard blocks; when the complexing agent is introduced, it can gradually dissolve the accumulated and blocked calcium salt precipitates. When it dissipates to a certain extent, the partition net 8 is no longer blocked, and the screw conveyor 5 can normally transport the dredger fill. At this time, the impeller 22 rotates and the generator 23 continues to generate electricity, and the solenoid valve 47 is energized and closed. At this time, the amount of the complexing agent introduced into the inside is sufficient to solve the problem of inhibiting the production of calcium salt precipitates inside the dredger fill, thereby ensuring that the dredger fill can be correctly solidified and avoiding the problem of a large amount of precipitates generated during the solidification of high-salt-content soil.

[0043] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0044] Working principle: When the hydraulic fill soil is solidified, the hydraulic fill soil is placed inside the main box 1. The solidifying agent enters the inside of the feeding box 31 through the feeding pipe 32. By starting the screw conveyor 5, the hydraulic fill soil inside the main box 1 can be conveyed into the screw conveyor 5 through the connecting pipe 6. The hydraulic fill soil is in an initial state of soil with a relatively high water content, and when it is completely solidified, it is similar to gravel in shape. Both states can be conveyed by the screw conveyor 5 without causing the hydraulic fill soil to block inside the screw conveyor 5. Then it is discharged back into the main box 1 through the discharge hopper 7. When the hydraulic fill soil passes through the discharge hopper 7, it quickly passes through the inside of the discharge hopper 7 under the action of its own gravity and the thrust generated by the screw conveyor 5. The rapidly flowing hydraulic fill soil can deflect the impeller 22. By the rotation of the impeller 22, the generator 23 can be driven to rotate. By the rotation of the generator 23, electricity can be generated (the power of the screw conveyor 5 is constant during operation, the flow rate of the hydraulic fill soil is basically unchanged during flow, the electricity generated by the generator 23 tends to be stable, and the generator 23 has two states: non - generating and generating state). After the electricity is generated, the generated electricity powers the electromagnet 320 and the solenoid valve 47. After the electromagnet 320 is energized, it generates a magnetic force. The screw conveyor 5 conveys the hydraulic fill soil stably, which can ensure the stable rotation of the impeller 22. The stable rotation of the impeller 22 keeps the power generation of the generator 23 stable. The stable current can ensure that the electromagnet 320 generates a stable magnetic force. The magnetic force between the electromagnet 320 and the magnet block 318 generates a repulsive force under the action of the like - pole repulsion of the same - name magnetic poles. The repulsive force and the elastic force of the spring 321 are balanced within a certain range (specifically, according to the actual situation and requirements, the relevant parameters and configurations of the generator are selected to meet the generated electricity to satisfy the magnetic force generated after the electromagnet is energized, and to conform to and match the spring). At this time, the positions of the magnet block 318 and the upper vertical plate 317 just ensure that the first gear 313 and the third gear 315 can be meshed within a certain range, ensuring that the first gear 313 and the third gear 315 can be normally meshed and transmitted. At this time, the first motor 35 rotates to drive the partition 39 to rotate through the third gear 315, the first gear 313, the cross - rotating rod 311, the back rod 310, and the rotating rod 38. By the continuous rotation of the partition 39, it is ensured that the solidifying agent entering between the partitions 39 through the feeding pipe 32 can be continuously discharged through the discharge port 37. The solidifying agent discharged through the discharge port 37 falls into the inside of the lower discharge hopper 7. The continuous conveyance of the solidifying agent in cooperation with the continuously conveyed hydraulic fill soil inside the discharge hopper 7 can synchronously convey the mixture of the two into the main box 1. At this time, with the rotation of the inner rotating cylinder 44 driving the outer stirring rods to stir and mix the internal solidifying agent and hydraulic fill soil, the stirring and mixing efficiency and mixing effect can be improved;

[0045] When the salt content in the dredger fill is low or there is no salt, rapid solidification of the dredger fill can be achieved through continuous mixing of the curing agent. When the salt content in the dredger fill is high, calcium salt precipitate lumps will be generated when the curing agent reacts with the high-salt soil. The relatively large mass of the calcium salt precipitate lumps will accumulate above the partition net 8 at the bottom of the main box 1, and multiple accumulated calcium salt precipitate lumps will block the partition net 8. Only when the salt content of the dredger fill is high can it react quickly with the curing agent to produce relatively large precipitate lumps and block the partition net 8. When the internal salt content is low or there is no salt, no precipitate lumps are produced or the produced precipitate lumps are small, and the small particles will not block the partition net 8 and do not affect the overall solidification effect of the dredger fill. The blockage of the partition net 8 prevents the dredger fill from entering the screw conveyor 5 through the connecting pipe 6. At this time, the discharge hopper 7 does not discharge the dredger fill inside. After losing the driving force of the dredger fill flow, the impeller 22 cannot continue to rotate, the generator 23 stops generating electricity, and the electromagnet 320 loses power supply, causing the electromagnet 320 to lose its magnetic force. There is no longer a repulsive force between the electromagnet 320 and the magnet block 318, and the inside of the electromagnet 320 is an iron core. At this time, the magnet block 318 can attract the iron core inside the electromagnet 320, so that the magnet block 318 approaches and adsorbs on the electromagnet 320. The magnet block 318 has a relatively large magnetic force. When the electromagnet 320 is powered off, the attraction force between the magnet block 318 and the iron core of the electromagnet 320 is relatively large, and the cross-shaped rotating rod 311 and the back rod 310 are connected by means of a ball connection, and the friction force between the two is small, so as to ensure that the magnet block 318 has enough force to move. The sliding of the magnet block 318 will drive the upper vertical plate 317 to move synchronously. At this time, the first gear 313 disengages from the third gear 315, and the second gear 314 is engaged with the residual gear 316. And the design of the cross-shaped rotating rod 311 and the back rod 310 ensures that the rotating shaft 312 can move back and forth without affecting the transmission between the two. The residual gear 316 is driven to rotate by the first motor 35. In the initial state, the residual gear 316 is in an idling state, and the rotation speed of the first motor 35 is low, so that no excessive eccentric force is generated and does not affect the overall rotation stability. The intermittent movement of the second gear 314 can be realized through the residual gear 316, the intermittent movement of the rotating rod 38 and the partition plate 39 can be realized through the intermittent movement of the second gear 314. Through the intermittent rotation of the partition plate 39, the curing agent between the two partition plates 39 can be put into the main box 1 every once in a while. When the salt content in the dredger fill is high, the curing agent is switched to multiple small doses. Add multiple times and fully stir with the stirring rod each time to make the curing agent react preliminarily with the dredger fill, and then add the next batch. This can avoid the problem of excessive local calcium ion concentration caused by a large amount of curing agent added at one time to a certain extent, and then avoid the problem of rapid reaction to generate a large amount of precipitation;

[0046] According to the above, it is possible to automatically judge the salt content in the dredger fill and automatically switch the feeding mode of the curing agent: when the salt content in the dredger fill is low or there is no salt, the curing agent is continuously added. The continuous addition method of the curing agent is more efficient. When the salt content in the dredger fill is high, the method of adding in small amounts multiple times is adopted, which can effectively avoid the formation of a large amount of precipitation;

[0047] When the rotating cylinder 44 rotates, the second motor 43 drives the rotating cylinder 44 to rotate. When the discharge hopper 7 normally discharges the dredger fill, the generator 23 generates electricity. At this time, the solenoid valve 47 is energized, and the energized solenoid valve 47 is in a closed state. The complexing agent in the external complexing agent storage container is transported through the feeding pipe 46. The complexing agent is a liquid, and the complexing agent introduced into the inside of the feeding pipe 46 is blocked by the solenoid valve 47 and cannot enter the inside of the communication box 42. When the generator 23 stops generating electricity, it indicates that calcium salt precipitation hard blocks have been generated. At this time, the solenoid valve 47 is de-energized, and the de-energized solenoid valve 47 is in a communicating state. The external complexing agent enters the inside of the communication box 42 through the feeding pipe 46, and the complexing agent is introduced into the inside of the rotating cylinder 44 through the communication groove 45. The complexing agent is introduced into the calcium salt precipitation hard blocks accumulated on the lower partition net 8 through the rotating cylinder 44. The complexing agent can prevent calcium ions from combining with other anions to form precipitation. Because the complexing agent has a strong binding ability with calcium ions, it will preferentially combine with calcium ions to make the calcium ions in a relatively stable complex state, thereby removing the already generated calcium salt precipitation hard blocks and preventing the generation of subsequent calcium salt precipitation hard blocks; when the complexing agent is introduced, it can gradually dissolve the accumulated and blocked calcium salt precipitation. When it dissipates to a certain extent, the partition net 8 is no longer blocked, and the screw conveyor 5 can normally transport the dredger fill. At this time, the impeller 22 rotates and the generator 23 continues to generate electricity, and the solenoid valve 47 is energized and closed. At this time, the amount of the complexing agent introduced into the inside is sufficient to solve the problem of inhibiting the production of calcium salt precipitation in the dredger fill, thereby ensuring that the dredger fill can be correctly solidified and avoiding the problem of a large amount of precipitation generated during the solidification of high-salt-content soil;

[0048] After curing for a certain period of time, the dredger fill is completely cured. At this time, by opening the discharge valve 9, the cured dredger fill can be discharged, and the valve provided between the connecting pipe 6 and the main body box 1 is closed during the discharge to prevent the dredger fill from continuing to enter the inside of the connecting pipe 6.
