Description

Technical Field

[0001] This invention belongs to the field of engineering construction equipment technology, and in particular relates to a molded bag filling vessel and a filling method. Background Technology

[0002] Geotextile bag construction is a method of utilizing soft soil by filling bags with it. Geotextile bags can be used to construct structures such as dams. In water-based construction, geotextile bag engineering vessels are required for filling and dumping the bags. For example... Figure 1 As shown, in a traditional geotextile engineering vessel 1', geotextile bags are laid underwater, and then soft soil is filled into the geotextile bags through the filling port 2' using the pumping equipment 3' on the vessel; or the geotextile bags are laid on the deck, filled by the pumping equipment 3', and then thrown to the bottom of the water. However, the following problems exist in using traditional geotextile filling vessels for geotextile filling construction: (1) In order to match the filling equipment of traditional geotextile filling vessels, the filling port of the geotextile is usually small. It is usually necessary to fill several filling ports on the geotextile separately to fill the entire geotextile. This requires frequent connection of the filling equipment and filling ports, making the operation cumbersome; (2) Due to the limitation of the filling port of the geotextile, the filling flow rate that traditional geotextile filling vessels can adapt to is small (generally not exceeding 100 cubic meters per hour), and cannot directly accept the filling or dredging speed of several hundred cubic meters per hour of dredging equipment such as dredgers; (3) The thickness of the geotextile soil unit completed in a single filling is small (generally not exceeding 2 meters). When the water depth is large, multiple layers need to be stacked to drain the water. Therefore, how to provide a geotextile filling vessel with higher filling efficiency is a technical problem that urgently needs to be solved. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a molded bag filling vessel and filling method, which can significantly improve the efficiency of molded bag filling.

[0004] This invention provides a molded bag filling vessel, comprising:

[0005] The hull has an opening for the mold bag to pass through and for filling operations, and the top of the mold bag is open.

[0006] A molded bag clamping device includes multiple sets of clamping components disposed on the hull. The multiple sets of clamping components are distributed around the working opening to jointly clamp the outer periphery of the top opening of the molded bag, so that the molded bag is suspended in the working opening and the top opening is kept open.

[0007] The molding bag tensioning device includes four tensioning components located at the four corners of the hull near the working opening. The four tensioning components are inserted into the molding bag from the four corners of the top opening of the molding bag to stretch the molding bag downwards.

[0008] In some embodiments, the tensioning component includes:

[0009] The support base is fixedly connected to the hull and has a cantilever extending toward the working port.

[0010] A support column, which is set vertically, has its upper end slidably connected to the cantilever to rise and fall vertically relative to the cantilever.

[0011] In some embodiments, there are two sets of clamping components, which are arranged opposite each other on opposite sides of the working opening. The two sets of clamping components clamp the edges of the top opening of the molded bag on opposite sides in the horizontal direction, so that the top opening of the molded bag is in an open state. Alternatively, multiple sets of clamping components are provided on opposite sides of the working opening. The clamping components clamp the outer wall of the top opening of the molded bag in the vertical direction. Multiple sets of clamping components on the same side jointly clamp the same side of the molded bag. The clamping components on opposite sides clamp the opposite sides of the molded bag, so that the top opening of the molded bag is in an open state.

[0012] In some embodiments, the clamping assembly includes a clamping sleeve, a core column, and a suspension member for connecting the molded bag; the clamping sleeve is fixedly connected to the hull, and a slit extending through the clamping sleeve along its length is opened on the side wall of the clamping sleeve facing the working port; a core column stop is provided at one axial end of the clamping sleeve; the core column is sleeved inside the clamping sleeve, and one axial end of the core column abuts against the core column stop; one end of the suspension member is located inside the clamping sleeve and sleeved outside the core column, and the other end extends out from the slit of the clamping sleeve to the outside of the clamping sleeve to connect the molded bag.

[0013] In some embodiments, the suspension component includes a cloth sleeve fitted over the core post and a connecting strap for connecting the molded bag. One end of the connecting strap is located inside the clamping sleeve and connected to the outer periphery of the cloth sleeve, and the other end extends from the gap of the clamping sleeve to the outside of the clamping sleeve to connect the molded bag.

[0014] In some embodiments, there are multiple connecting straps, which are spaced apart along the length of the fabric sleeve on the outer periphery of the fabric sleeve. Each connecting strap is used to connect a molded bag. The clamping assembly also includes a cutting blade for cutting the fabric sleeve to separate it from the core column. The cutting blade is disposed on the inner wall of the clamping sleeve at the end where the core column stop is located. The end of the cutting blade away from the clamping sleeve contacts the outer periphery of the core column and is provided with a cutting edge. The cutting edge is arranged in a direction away from the core column stop. The molded bag clamping device also includes a fabric sleeve roll for winding and recycling the cut fabric sleeve. The fabric sleeve roll is arranged in a one-to-one correspondence with the clamping assembly. The fabric sleeve roll is located close to the clamping sleeve and on the side of the clamping sleeve where the core column stop is located.

[0015] In some embodiments, the bottom inner wall of the clamping sleeve is provided with a core column support for supporting the core column. There are multiple core column supports, which are distributed along the length of the clamping sleeve. Each core column support includes a support fixedly connected to the inner wall of the clamping sleeve and a core column support wheel rotatably connected to the support. The axle of the core column support wheel is perpendicular to the axis of the clamping sleeve. When the core column is not covered with a cloth cover, the outer circumference of the core column support wheel rolls against the outer circumference of the core column. When the cloth cover is covered with the core column, the core column support wheel rolls to allow the cloth cover to enter between the core column support wheel and the core column.

[0016] In some embodiments, the hull is provided with an auxiliary working deck for laying out geotextile bags and / or connecting geotextile bag suspension components. The auxiliary working deck is located near the working opening. A geotextile bag reel is provided on the auxiliary working deck, and geotextile bags to be filled are wound on the geotextile bag reel.

[0017] In some embodiments, the working port is located near the stern of the hull, and the stern of the hull has a groove for the molded bag to be removed after filling, the groove extending from the side wall of the working port to the stern of the hull.

[0018] In addition, the present invention also provides a method for filling geotextile bags with soil, using the geotextile bag filling vessel described in any of the above technical solutions for the filling operation, including the following steps:

[0019] Filling vessel positioning: After the mold bag filling vessel arrives at the preset position, it anchors and positions itself.

[0020] Fixing the mold bag: Place the mold bag to be filled into the working port of the mold bag filling vessel with the open end facing upward, and use multiple sets of clamping components arranged around the working port to clamp the outer periphery of the top opening of the mold bag, so that the mold bag is suspended in the working port and the top opening is kept open.

[0021] Tensioning the membrane bag: Insert the four tensioning components at the four corners of the working port into the membrane bag from the four corners of the top opening of the membrane bag to stretch the membrane bag downwards until the bottom of the membrane bag is close to the bottom of the water;

[0022] Filling with soil: The engineering vessel used for dumping or blowing soil approaches the formwork bag filling vessel and positions itself next to it. The engineering vessel then dumps or blows soil into the formwork bag through the open top opening until the formwork bag is full, forming formwork bag soil.

[0023] Release and seal the mold bag: Release the clamping components from the mold bag and the tensioning components from the mold bag to release the mold bag, seal the top opening of the mold bag, and obtain the mold bag soil.

[0024] In some embodiments, the specific steps of using the stretching component to stretch the molded bag downwards in the stretching step are as follows: driving the support column of the stretching component to descend vertically relative to the cantilever, so as to push the bottom of the molded bag downwards using the lower end of the support column; in the releasing and sealing step, driving the support column to rise vertically relative to the cantilever, so as to release the stretching component from the molded bag.

[0025] In some embodiments, the step of securing the mold bag includes, before placing the mold bag into the working port, spreading the mold bag on the auxiliary working deck of the mold bag filling vessel, with the top opening of the mold bag facing upwards and straightening the edges of the top opening, and connecting the suspension member to the outer periphery of the top opening of the mold bag; when clamping the mold bag using the clamping assembly, the suspension member is fitted over the core column of the clamping assembly from one axial end and moved to the other axial end of the core column, and during the movement of the suspension member, the suspension member passes through the gap of the clamping sleeve so that the suspension member is fitted between the core column and the clamping sleeve; in the step of releasing and sealing the mold bag, the clamping assembly releases the clamping of the mold bag by disengaging the suspension member from the core column and the clamping sleeve, or by cutting off the connection between the suspension member and the mold bag.

[0026] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0027] 1. The mold bag filling vessel provided by the present invention is equipped with mold bags with an open top. Multiple sets of clamping components of the mold bag clamping device jointly clamp the outer periphery of the open top of the mold bag, so that the mold bag is suspended in the working port of the hull and the open top is kept open. At the same time, four supporting components of the mold bag supporting device open the mold bag from the inside downward, so that the mold bag is kept open. During filling, the mud and sand collected by dredging equipment such as dredgers can be directly thrown or blown into the mold bag at high speed from the open top of the mold bag without the need for multiple switching of filling ports. It can meet the throwing or blowing speed of hundreds or even thousands of cubic meters per hour, which significantly improves the filling efficiency of the mold bag.

[0028] 2. The mold bag filling vessel provided by the present invention, through the cooperation of the mold bag clamping device and the mold bag tensioning device, makes the mold bag stand upright, and it can fill a large mold bag of soil from the bottom of the water to the surface of the water, which can meet the requirement of filling and draining water in one go, and overcomes the problem that the traditional mold bag soil is thin and requires multiple layers to be stacked before water can be drained.

[0029] 3. The soil filling method for geotextile bags provided by the present invention utilizes a geotextile bag filling vessel equipped with a geotextile bag clamping device and a geotextile bag tensioning device for filling. Multiple sets of clamping components jointly clamp the outer periphery of the top opening of the geotextile bag, so that the geotextile bag is suspended in the working opening and the top opening is kept open. The tensioning components push the geotextile bag downward until the bottom of the geotextile bag is close to the bottom of the water, so that the soil is directly thrown or blown into the geotextile bag through the open top opening. It can meet the throwing or blowing speed of several hundred cubic meters or even thousands of cubic meters per hour, which significantly improves the filling efficiency of geotextile bags.

[0030] 4. The soil filling method for geotextile bags provided by the present invention makes the geotextile bags stand upright and are stretched to the bottom close to the bottom of the water, so as to fill large geotextile bags from the bottom of the water to the surface of the water, which can meet the requirements of filling and draining water in one go, and overcomes the problem that the traditional geotextile bags are thin and require multiple layers to drain water.

[0052] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0053] In the description of this invention, it should be understood that the terms "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0054] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0055] As attached Figure 2-Figure 7 As shown, in an illustrative embodiment of the bag-filling vessel of the present invention, the bag-filling vessel includes a hull 1, a bag-clamping device 2, and a bag-stretching device; the hull 1 is provided with a working opening a for the bag 4 to pass through and for filling operations, and the top of the bag 4 is open; the bag-clamping device 2 includes multiple sets of clamping components 21 disposed on the hull 1, the multiple sets of clamping components 21 being distributed around the working opening a, to jointly clamp the outer periphery of the top opening of the bag 4, so that the bag 4 is suspended in the working opening a and the top opening is kept open; the bag-stretching device includes four stretching components 3 disposed on the hull 1 near the four corners of the working opening a, the four stretching components 3 being inserted into the bag 4 from the four corners of the top opening of the bag 4 to stretch the bag 4 downward.

[0056] The aforementioned bag-filling vessel is equipped with a bag 4 with an open top. Multiple clamping components 21 of the bag clamping device 2 clamp the outer periphery of the open top of the bag 4, suspending the bag 4 within the working opening a of the hull 1 and keeping the open top in an open state. At the same time, four tensioning components 3 of the bag tensioning device push the bag 4 downward from the inside, thus keeping the bag 4 in an open state. During filling, silt and sand collected by dredging equipment such as dredgers can be directly thrown or blown into the bag 4 at high speed through the open top, without the need for multiple switching of the filling port. It can meet the filling or blowing speed of several hundred cubic meters or even thousands of cubic meters per hour, significantly improving the filling efficiency of the bag 4. Meanwhile, the aforementioned mold bag filling vessel, through the cooperation of the mold bag clamping device 2 and the mold bag tensioning device, makes the mold bag 4 stand upright, and it can fill a large mold bag of soil from the bottom to the surface of the water, which can meet the requirement of filling and draining water in one go, overcoming the problem that the traditional mold bag soil is thin and requires multiple layers to be stacked before water can be drained.

[0057] like Figure 2As shown, in this embodiment, the tensioning assembly 3 includes a support base 31 and a support column 32. The support base 31 is fixedly connected to the hull 1 and has a cantilever 311 extending towards the working opening a. The support column 32 is vertically arranged, and its upper end is slidably connected to the cantilever 311 to rise and fall vertically relative to the cantilever 311. The tensioning assembly 3, through the cantilever 311 provided by the support base 31, suspends the support column 32 within the working opening a. The support column 32 descends relative to the cantilever 311, extending into the mold bag 4 within the working opening a and downwardly expanding the mold bag 4. After the mold bag 4 is filled, the support column 32 rises relative to the cantilever 311, causing the mold bag 4 to detach from the tensioning assembly 3. Simultaneously, by expanding the mold bag 4 with the support column 32, the bending resistance of the support column 32 can be used to resist the impact force of the water flow. It should be noted that the lifting of the support column 32 relative to the cantilever 311 can adopt existing lifting drive structures, such as lifting drive structures that use gears and racks, or lifting drive structures that use winches and pulleys, etc., which will not be elaborated here.

[0058] like Figure 2 As shown, in this embodiment, there are two sets of clamping components 21, which are positioned opposite each other on opposite sides of the working opening a. The two sets of clamping components 21 clamp the opposite edges of the top opening of the molded bag 4 horizontally, keeping the top opening of the molded bag 4 open. By clamping the molded bag 4 horizontally with the two sets of clamping components 21, the downward force generated during the filling process of the molded bag 4 can be resisted, thereby maintaining the top position of the molded bag 4 with minimal descent and ensuring the top opening remains open. It should be noted that the clamping components 21 can be various forms of clamping devices such as clips, hooks, straps, ties, zippers, and buckles. It should also be noted that the clamping position of the horizontally positioned clamping components 21 on the molded bag 4 can be determined according to the desired top surface height of the filled molded bag soil, generally above the water surface, so that the top of the molded bag 4 extends outwards to prevent the soil material inside the molded bag 4 from spreading outwards.

[0059] like Figure 3-Figure 6As shown, in this embodiment, the clamping assembly 21 specifically includes a clamping sleeve 211, a core post 212, and a suspension member 213 for connecting the molded bag 4. The clamping sleeve 211 is fixedly connected to the hull 1. A slit is opened on the side wall of the clamping sleeve 211 facing the working port a, extending through the clamping sleeve 211 along its length. A core post stop 214 is provided at one axial end of the clamping sleeve 211. The core post 212 is sleeved inside the clamping sleeve 211, and one axial end of the core post 212 abuts against the core post stop 214. One end of the suspension member 213 is located inside the clamping sleeve 211 and sleeved outside the core post 212, and the other end extends out from the slit of the clamping sleeve 211 to the outside of the clamping sleeve 211 to connect the molded bag 4. During construction, the core posts 212 of the two sets of clamping components 21 can be pre-fitted into the corresponding clamping sleeves 211. The suspension members 213 of the two sets of clamping components 21 are fixedly connected to the edges of opposite sides of the top opening of the mold bag 4. The suspension members 213 of the two sets of clamping components 21 are respectively fitted between the core posts 212 and the clamping sleeves 211 of the two sets of clamping components 21. The specific steps for fitting the suspension members 213 between the core posts 212 and the clamping sleeves 211 are as follows: starting from the end of the core post 212 away from the core post stop 214, the suspension member 213 is fitted over the core post 212 and moved to the other end. During the movement of the suspension member 213, the suspension member 213 passes through the gap of the clamping sleeve 211 so that the suspension member 213 is fitted between the core post 212 and the clamping sleeve 211. It is understandable that, instead of pre-fitting the core post 212 into the clamping sleeve 211, the suspension member 213 can be fitted over the core post 212. Then, the core post 212 with the suspension member 213 fitted over it can be inserted into the clamping sleeve 211 from the end without the core post stop 214. When the core post 212 is inserted into the clamping sleeve 211, the suspension member 213 passes through the gap in the clamping sleeve 211, so that the end of the suspension member 213 fitted over the core post 212 can enter the clamping sleeve 211 together with the core post 212, so that the suspension member 213 fits between the core post 212 and the clamping sleeve 211. Using the aforementioned clamping assembly 21, during the filling process, the suspension member 213 bears a downward force, while the clamping sleeve 211 and the core column 212 provide upward support for the suspension member 213 to counteract the downward pulling force. This ensures that the top position of the molded bag 4 remains essentially constant and the top opening remains open throughout the filling process. In the clamping assembly 21, the clamping sleeve 211 serves as an external support, and the suspension member 213 is connected to the core column 212 inside the clamping sleeve 211 via a sleeve connection. The gap in the clamping sleeve 211 restricts the rotation of the suspension member 213 relative to the core column 212, keeping the suspension member 213 essentially stationary during the filling process. The suspension member 213 experiences stable and uniform force, thereby reducing the possibility of tearing and ensuring stable clamping of the molded bag 4 during the filling process.Meanwhile, in the aforementioned clamping assembly 21, the external clamping sleeve 211 also serves as a protective sleeve for the suspension component 213, which can effectively prevent the suspension component 213 from breaking due to wear and prevent accidental contact with the suspension component 213 from causing the suspension component 213 to detach from the core column 212, thus helping to ensure stable clamping of the mold bag 4 during the filling process. Furthermore, in the aforementioned clamping assembly 21, the core column stop 214 blocks the core column 212, ensuring that the core column 212 can only enter the clamping sleeve 211 from the end without the core column stop 214. When connecting the suspension member 213, the suspension member 213 also enters from the end of the clamping sleeve 211 without the core column stop 214. At this time, the core column 212 is stopped by the core column stop 214, preventing it from moving with the entry of the suspension member 213, thus allowing the suspension member 213 to be fitted over the core column 212. Simultaneously, by blocking the core column 212 with the core column stop 214, the core column 212 is prevented from detaching from the clamping sleeve 211 due to axial movement during the filling process, which helps to ensure stable clamping of the mold bag 4 during the filling process.

[0060] like Figure 5 As shown, in this embodiment, the suspension component 213 specifically includes a cloth sleeve 2131 sleeved outside the core column 212 and a connecting strap 2132 for connecting the mold bag 4. One end of the connecting strap 2132 is located inside the clamping sleeve 211 and connected to the outer periphery of the cloth sleeve 2131, and the other end extends out from the gap of the clamping sleeve 211 to the outside of the clamping sleeve 211 to connect the mold bag 4. The suspension component 213 uses a combination of a fabric sleeve 2131 and a connecting strap 2132. On one hand, the fabric sleeve 2131 connects to the core column 212, increasing the contact area and ensuring even stress distribution between the core column 212 and the fabric sleeve 2131, reducing the possibility of tearing. On the other hand, the connecting strap 2132 connects to the top open edge of the molded bag 4, increasing the connection length and improving the connection strength between the suspension component 213 and the molded bag 4. This effectively prevents the suspension component 213 from detaching from the molded bag 4, ensuring stable clamping of the molded bag 4 during filling. It is understood that the fabric sleeve 2131 is made of flexible material and can be continuously laid out as a long cylindrical component or intermittently laid out as a ring-shaped component; similarly, the connecting strap 2132 is also made of flexible material and can be laid out continuously or intermittently. Additionally, it should be noted that those skilled in the art may also use other forms of suspension components 213, such as: using a strap as the suspension component 213, with one end of the strap sewn onto the molded bag 4 and the other end directly tied to the outside of the core column 212; or using a ring-shaped component in conjunction with the strap as the suspension component 213, with the ring-shaped component pre-fitted onto the outside of the core column 212, one end of the strap sewn onto the molded bag 4 and the other end tied to the ring-shaped component.

[0061] like Figure 6As shown, in this embodiment, the bottom inner wall of the clamping sleeve 211 is provided with a core pillar support 215 for supporting the core pillar 212. Multiple core pillar supports 215 are distributed along the length of the clamping sleeve 211 within the clamping sleeve 211. By supporting the core pillar 212 with the provided core pillar supports 215, direct contact between the core pillar 212 and the bottom inner wall of the clamping sleeve 211 is avoided, facilitating the placement of the cloth cover 2131 over the core pillar 212. Specifically, as... Figure 7 As shown, the core pillar support 215 includes a support 2151 fixedly connected to the inner wall of the clamping sleeve 211 and a core pillar support roller 2152 rotatably connected to the support 2151. The axle of the core pillar support roller 2152 is perpendicular to the axis of the clamping sleeve 211. When the core pillar 212 is not fitted with the cloth sleeve 2131, the outer circumference of the core pillar support roller 2152 rolls against the outer circumference of the core pillar 212. When the cloth sleeve 2131 is fitted onto the core pillar 212, the core pillar support roller 2152 rolls to allow the cloth sleeve 2131 to enter between the core pillar support roller 2152 and the core pillar 212. The core pillar 212 is supported by the core pillar support roller 2152, and the rolling of the core pillar support roller 2152 facilitates the cloth sleeve 2131 to pass between the core pillar support roller 2152 and the core pillar 212 to be fitted onto the core pillar 212. Preferably, the rim of the core roller 2152 is provided with rim teeth spaced circumferentially. By using a core roller 2152 with rim teeth, when the cloth sleeve 2131 passes between the core roller 2152 and the core 212, only intermittent point-like compression is applied to the wall of the cloth sleeve 2131, thus avoiding continuous compression of the cloth sleeve 2131 which would reduce its strength and create a continuous low-strength zone that would affect the clamping effect. Specifically, the core roller 2152 includes a first wheel segment 2152a, a second wheel segment 2152b, and a third wheel segment 2152c arranged sequentially in the wheel axle direction. The first wheel segment 2152a and the third wheel segment 2152c are symmetrically arranged. The rim teeth corresponding to the first wheel segment 2152a and the third wheel segment 2152c are trapezoidal rim teeth 2153, while the rim teeth of the second wheel segment 2152b are needle-shaped rim teeth 2154. A core support roller 2152 with trapezoidal rim teeth 2153 and needle-shaped rim teeth 2154 is used. When the cloth sleeve 2131 passes between the core support roller 2152 and the core 212, the tip of the needle-shaped rim teeth 2154 can penetrate the outer wall of the cloth sleeve 2131, thereby minimizing the relative movement between the rim tooth surface of the core support roller 2152 and the outer wall of the cloth sleeve 2131, and thus reducing the frictional damage of the rim tooth surface of the core support roller 2152 to the cloth sleeve 2131.

[0062] After one molded bag 4 is filled, the currently filled molded bag 4a can be released from the molded bag clamping device 2 by detaching the connecting strap 2132 from the molded bag 4 and detaching the cloth cover 2131 from the core post 212. The molded bag clamping device 2 is used to clamp the next molded bag 4b for the filling operation of the next molded bag 4b. In order to facilitate the assembly line operation of molded bag 4 filling, such as Figures 8-11 As shown in another illustrative embodiment of the bag-filling vessel of the present invention, the cloth sleeve 2131 is a continuous long tube, and there are multiple connecting straps 2132. The multiple connecting straps 2132 are arranged at intervals along the length direction of the cloth sleeve 2131 on the outer periphery of the cloth sleeve 2131, and each connecting strap 2132 is used to connect a bag 4. After the current bag 4a is connected to a connecting strap 2132, the current bag 4a connected to the connecting strap 2132 enters the working port a after the part of the cloth sleeve 2131 corresponding to the connecting strap 2132 is put on the core column 212. At this time, the next bag 4b can be connected to the next connecting strap 2132 next to the working port a. When the current bag 4a in the working port a is filled and removed from the working port a, the cloth sleeve 2131 is pulled so that the part of the cloth sleeve 2131 corresponding to the next connecting strap 2132 is put on the core column 212, so that the next bag 4b can directly enter the working port a for filling, thereby realizing a streamlined operation. To facilitate the removal of the cloth sleeve 2131 from the core post 212, such as Figure 9 and Figure 10 As shown, the clamping assembly 21 also includes a cutting edge 216 for slicing the fabric sleeve 2131 to disengage it from the core post 212. The cutting edge 216 is disposed on the inner wall of the clamping sleeve 211 at the end where the core post stop 214 is located. The end of the cutting edge 216 away from the clamping sleeve 211 contacts the outer periphery of the core post 212 and has a cutting edge facing away from the core post stop 214. By pulling the fabric sleeve 2131 towards the cutting edge 216, the cutting edge 216 slices the fabric sleeve 2131 as it passes the cutting edge 216, thereby disengaging the fabric sleeve 2131 from the core post 212. When the fabric sleeve 2131 is a continuous long cylinder connected to multiple connecting straps 2132, by pulling the fabric sleeve 2131 towards the cutting edge 216, the portion of the fabric sleeve 2131 currently fitted onto the core post 212 can be detached from the core post 212 under the cutting of the cutting edge 216. This releases the current mold bag 4a connected to the connecting strap 2132 corresponding to that portion of the fabric sleeve 2131, and simultaneously allows the portion of the fabric sleeve 2131 corresponding to the next connecting strap 2132 to automatically fit over the core post 212, achieving automatic clamping of the next mold bag 4b, and realizing automated assembly line operation for filling the mold bags 4. Preferably, as follows... Figure 10 As shown, the cutting edge is angled to facilitate cutting the fabric sleeve 2131. Further, as... Figure 8 and Figure 11As shown, the mold bag clamping device 2 also includes a fabric sleeve roll 22 for winding and recycling the cut fabric sleeve 2131. The fabric sleeve roll 22 is arranged one-to-one with the clamping assembly 21. The fabric sleeve roll 22 is located close to the clamping sleeve 211 and on the side of the clamping sleeve 211 where the core column stop 214 is provided. By winding the cut fabric sleeve 2131 with the fabric sleeve roll 22, the fabric sleeve 2131 is recycled, which is beneficial to the management of construction waste. On the other hand, the fabric sleeve 2131 is pulled so that the part of the fabric sleeve 2131 corresponding to each connecting strap 2132 passes through the clamping sleeve 211 without the cutting edge 216 one by one and is placed on the outside of the core column 212. Then, after filling, it is released from the core column 212 from the end of the clamping sleeve 211 with the cutting edge 216, realizing the continuous automatic clamping of the mold bag 4 and realizing the automated assembly line operation of filling the mold bag 4.

[0063] To facilitate the spreading of the molding bag 4 and the connection of the suspension component 213, such as Figure 8 As shown, in this embodiment, the hull 1 is provided with an auxiliary working deck 11 for laying out the mold bag 4 and / or connecting the mold bag 4 suspension component 213. The auxiliary working deck 11 is located near the working opening a. A mold bag roll 5 is provided on the auxiliary working deck 11, and the mold bag 4 to be filled is wound on the mold bag roll 5.

[0064] To facilitate the removal of the filled mold bag 4 from the work port a for the filling of the next mold bag 4b, as follows: Figure 8 As shown, in this embodiment, the working port a is located near the stern of the hull 1, and the stern of the hull 1 has a groove b for the molded bag 4 to be removed after being filled. The groove b extends from the side wall of the working port a to the stern of the hull 1.

[0065] like Figure 12 As shown in another illustrative embodiment of the mold bag filling vessel of the present invention, multiple sets of clamping components 21 are respectively provided on opposite sides of the working port a. The clamping components 21 clamp the outer side wall of the top opening of the mold bag 4 in a vertical direction. Multiple sets of clamping components 21 located on the same side jointly clamp the same side of the mold bag 4. The clamping components 21 located on opposite sides clamp the opposite sides of the mold bag 4, so that the top opening of the mold bag 4 is in an open state. By using multiple sets of clamping components 21 to clamp the outer side wall of the top opening of the mold bag 4 in a vertical direction, the top opening of the mold bag 4 is kept in an open state while withstanding the impact force of water flow on the mold bag 4, thus preventing the mold bag 4 from shaking too much. It should be noted that the clamping components 21 used for vertically clamping the mold bag 4 can be the same clamping components 21 used for horizontally clamping the mold bag 4, except that one axial end of the core column 212 needs to be fixedly connected to the core column stop 214 to fix the core column 212.

[0066] Based on the aforementioned geotextile bag filling vessel, the present invention also provides a method for filling geotextile bags with soil, which uses the aforementioned geotextile bag filling vessel for filling operations, and includes the following steps:

[0067] S1 Filling Vessel Positioning: After the mold bag filling vessel arrives at the preset position, it anchors and remains in position;

[0068] S2 Fixed mold bag: The mold bag 4 to be filled is placed into the working port a of the mold bag filling ship with the open end facing upward, and multiple sets of clamping components 21 arranged around the working port a are used to clamp the outer periphery of the top opening of the mold bag 4, so that the mold bag 4 is suspended in the working port a and the top opening is kept open.

[0069] S3 Tensioning the mold bag: Insert the four tensioning components 3 at the four corners of the working port a into the mold bag 4 from the four corners of the top opening of the mold bag 4 to stretch the mold bag 4 downwards until the bottom of the mold bag 4 is close to the bottom of the water.

[0070] S4 Filling soil: The engineering vessel used for dumping or dredging soil approaches the formwork bag filling vessel and positions itself next to it. The engineering vessel uses the soil to dump or dredging soil into the formwork bag 4 through the open top opening until the formwork bag 4 is full, forming formwork bag soil.

[0071] S5 Release and seal the mold bag 4: Release the clamping components 21 from the mold bag 4 and the tensioning component 3 from the mold bag 4 to release the mold bag 4, seal the top opening of the mold bag 4, and obtain the mold bag soil.

[0072] The aforementioned method for filling geotextile bags utilizes a geotextile bag filling vessel equipped with a geotextile bag clamping device 2 and a geotextile bag tensioning device. Multiple clamping components 21 clamp the outer periphery of the top opening of the geotextile bag 4, suspending it within the working opening a while maintaining its open top. The tensioning components 3 then push the geotextile bag 4 downwards until its bottom is close to the water bottom, allowing soil to be directly dumped or blown into the bag through its open top opening. This method can achieve filling speeds of several hundred cubic meters or even thousands of cubic meters per hour, significantly improving the filling efficiency of the geotextile bag 4. Furthermore, this method keeps the geotextile bag 4 upright and stretched until its bottom is close to the water bottom, enabling the filling of large geotextile bags from the water bottom to the surface. This allows for one-time filling and drainage, overcoming the problem of traditional geotextile bags having a smaller thickness and requiring multiple layers for drainage.

[0073] It should be noted that in the step of stretching the formwork bag, the specific steps of using the stretching component 3 to stretch the formwork bag 4 downward are as follows: the support column 32 of the stretching component 3 is driven to descend vertically relative to the cantilever 311, so that the lower end of the support column 32 pushes the bottom of the formwork bag 4 downward; in the step of releasing and sealing the formwork bag, the support column 32 is driven to rise vertically relative to the cantilever 311 to release the stretching component 3 from the formwork bag 4. Preferably, in the step of stretching the formwork bag, the support column 32 is lowered to the bottom of the water, and the soil at the bottom of the water can provide support and fixation for the lower end of the support column 32, which can improve the resistance of the support column 32 and the formwork bag 4 it supports to water flow impact.

[0074] It should be noted that, in the process of fixing the mold bag, before placing the mold bag 4 into the working port a, the process includes spreading the mold bag 4 on the auxiliary working deck 11 of the mold bag filling vessel, with the top opening of the mold bag 4 facing upwards and the edges of the top opening straightened, and connecting the suspension member 213 to the outer periphery of the top opening of the mold bag 4; when using the clamping assembly 21 to clamp the mold bag 4, the suspension member 213 is fitted over the core column 212 from one axial end of the clamping assembly 21 and... The suspension member 213 moves to the other end of the axial direction of the core column 212. During the movement of the suspension member 213, the suspension member 213 passes through the gap of the clamping sleeve 211 so that the suspension member 213 is fitted between the core column 212 and the clamping sleeve 211. In the step of releasing and sealing the mold bag, the clamping assembly 21 releases the clamping of the mold bag 4 by disengaging the suspension member 213 from the core column 212 and the clamping sleeve 211, or by cutting off the connection between the suspension member 213 and the mold bag 4.

[0075] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0076] The above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the present invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in the present invention.
