Description

Technical Field

[0001] The utility model relates to the technical field of soft foundation treatment engineering, in particular to a drainage board inserting device and a board inserting machine. Background Art

[0002] Drainage boards, such as strip-shaped plastic drainage boards, are mainly used as vertical drainage channels in soft foundation treatment projects. For example, the plastic drainage board can be inserted into the bottom elevation of the soft foundation according to the design plane position and bottom elevation requirements by vibration or static pressure pile sinking method. At this time, the plastic drainage board inserted into the foundation soil layer serves as a drainage channel. Under the action of the upper load, the moisture in the soil layer is discharged out of the soil layer through the drainage board channel, thereby accelerating the settlement and consolidation of the soft foundation, so as to achieve the purpose of improving the bearing capacity of the soft foundation.

[0003] Since the plastic drain board is relatively soft, it cannot be directly inserted into the soil layer. At this time, the plastic drain board needs to be inserted into the interior of the casing pipe and extended to the boot door opening at the bottom end of the casing pipe, and fixed by fixings such as short steel bars set under the boot door. In the process of the casing pipe penetrating downward into the soil layer, the steel bars will drive the drain board to be inserted into the bottom elevation of the soil layer, and the two ends of the steel bars and the head end of the plastic drain board will be squeezed by the soil layer and relatively fixed, so as to keep the plastic drain board in the soil layer. At this time, you only need to pull out the casing pipe.

[0004] However, in the actual construction process where the casing pipe drives the plastic drain board downward into the soil layer, the silt in the complex soil layer will be squeezed into the interior of the casing pipe, causing the drain board to move up a certain distance (that is, the drain board does not stay accurately at the bottom elevation) during the pulling-up process of the casing pipe. This phenomenon is called "back-pulling", which will affect the quality of the project. Utility Model Content

[0005] The problem solved by the utility model is how to prevent the drainage board from generating a "backlash" phenomenon during the lifting process of the insertion structure after the drainage board is sent to the bottom elevation of the soil layer.

[0006] In order to solve the above problems, the utility model provides a drain board insertion device, including an insertion structure and a sealing structure, the insertion structure includes a sheath tube and a boot door, the boot door is installed at the bottom end of the sheath tube, the interior of the sheath tube is used to penetrate the drain board, and the bottom end of the drain board extends into the boot door; the side wall of the sheath tube is provided with a water inlet hole for water flow above the soil layer to enter, when the sheath tube is inserted into the soil layer, the water inlet hole is located at the water layer above the soil layer, the bottom end of the boot door is provided with an opening, the sheath tube, the boot door and the opening are connected in sequence from top to bottom to form a water flow channel connected to the water inlet hole, at least part of the sealing structure is arranged below the boot door, and the sealing structure is used to be sealed and connected to the opening of the boot door, the length of the sealing structure is greater than the bottom width of the boot door, and the sealing structure is used to connect the drain board, so that when the insertion structure is lifted, the bottom end of the drain board and the sealing structure are separated from the boot door together.

[0007] Optionally, the sealing structure includes a connecting portion and a sealing portion, the sealing portion is installed at the bottom end of the connecting portion, the connecting portion is embedded in the boot door from the opening and connected to the bottom end of the drain board, and the sealing portion is sealed and connected to the opening.

[0008] Optionally, the shape of the opening matches the shape of a portion of the sealing portion facing the opening.

[0009] Optionally, the insertion structure further includes a flexible connector, one end of which is connected to the sheath tube or the side wall of the boot door, and the other end of the flexible connector is connected to the sealing portion, and the sealing portion is used to move closer to or farther away from the boot door through the flexible connector.

[0010] Optionally, the drainage plate is snap-connected to the connecting portion.

[0011] Optionally, the connecting portion has a slot, and the drainage plate in the boot door has a bending portion, and the bending portion is engaged with the slot.

[0012] Optionally, the inner wall of the boot door near the sealing structure has a smooth surface for reducing friction with the drainage board.

[0013] Optionally, the boot door and the sheath tube are an integrally formed structure.

[0014] Compared with the prior art, the drain board insertion device in the utility model mainly includes an insertion structure and a sealing structure. Before the drain board is inserted to the bottom elevation of the soil layer through the insertion structure, the drain board needs to be connected to the sealing structure first. For example, a strip-shaped drain board is inserted from the top of the protective tube in the insertion structure, extended into the protective tube and extended downward to the boot door, and passed through the opening at the bottom end of the boot door to connect with the sealing structure under the boot door. Subsequently, a pulling force can be applied to the strip-shaped drain board from the outside of the protective tube to drive the sealing structure to move upward to approach the boot door by pulling the drain board, until the sealing structure is sealed and connected to the opening of the boot door, thereby realizing the boot installation process.

[0015] Subsequently, the insertion structure can move downward under the action of external force and be inserted into the soil layer to bring the drainage board in the insertion structure to the bottom elevation position of the soil layer. In the process of the insertion structure being inserted into the soil layer and bringing the drainage board to the bottom elevation position, the sealing structure is sealed with the bottom opening of the boot door, which can effectively prevent the silt in the soil layer from entering the boot door. In addition, since the water inlet hole is in the water layer above the soil layer, the water flow in the water layer above the soil layer will also enter the inside of the casing pipe from the water inlet hole of the casing pipe, so that the water flow channel of the entire insertion structure is filled with water, and the water flow in the insertion structure can communicate with the ambient water outside the insertion structure.

[0016] When the insertion structure is lifted, the water flow inside the insertion structure will flow downward under the action of gravity along the water flow channel formed by the casing pipe, the boot door and the opening connected in sequence, not only flushing the bottom end of the drain board out of the boot door from the opening, but also the water flow can prevent the silt in the soil layer from entering the boot door from the opening in the opposite direction. In this process, the silt around the bottom end of the drain board that has separated from the boot door will continuously squeeze the drain board and the part of the sealing structure that exceeds the bottom width of the boot door to form silt resistance, and because the sealing structure is connected to the bottom end of the strip-shaped drain board, the sealing structure has a certain pulling force on the bottom end of the drain board, so that the drain board and the sealing structure will accurately stay at the bottom elevation of the soil layer under the action of silt resistance, thereby effectively preventing the insertion structure from driving the drain board up a certain distance when lifted and causing the "back-draft" phenomenon, thereby ensuring the quality of the project.

[0017] The utility model also provides a plate insertion machine, including a drain plate and the drain plate insertion device as described above, and also including a vibrating hammer, a reel, a first guide wheel structure and a lifting device, wherein the insertion structure of the drain plate insertion device is installed at the bottom end of the vibrating hammer, and the lifting device is connected to the vibrating hammer and is used to drive the vibrating hammer to drive the insertion structure to move up and down; the first guide wheel structure is installed at a position where the vibrating hammer is close to the insertion structure, and the reel is installed on one side of the lifting device, and the reel is used to wind the drain plate, and the end of the drain plate away from the reel bypasses the first guide wheel structure and enters the insertion structure.

[0018] Since the board inserting machine includes the drainage board inserting device, the board inserting machine at least has all the technical effects of the drainage board inserting device, which will not be repeated here.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] In the description of this specification, the description with reference to the terms "embodiment", "one embodiment" and "one implementation" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or implementation are included in at least one embodiment or implementation of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or implementation. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or implementations in a suitable manner.

[0035] In order to solve the above technical problems, Figure 1As shown, the embodiment of the utility model provides a drainage board insertion device, including an insertion structure 2 and a sealing structure 3, wherein the insertion structure 2 includes a sheathing tube 21 and a boot door 22, wherein the boot door 22 is installed at the bottom end of the sheathing tube 21, wherein the interior of the sheathing tube 21 is used to penetrate the drainage board 1, and the bottom end of the drainage board 1 extends into the boot door 22; the side wall of the sheathing tube 21 is provided with a water inlet hole 211 for water flow above the soil layer to enter, and when the sheathing tube 21 is inserted into the soil layer, the water inlet hole 211 is located at the water layer above the soil layer, and the boot door 22 is An opening is provided at the bottom end, and the sheath tube 21, the boot door 22 and the opening are connected in sequence from top to bottom to form a water flow channel connected to the water inlet hole 211, at least part of the sealing structure 3 is arranged below the boot door 22, and the sealing structure 3 is used to be sealed and connected to the opening of the boot door 22, the length of the sealing structure 3 is greater than the bottom width of the boot door 22, and the sealing structure 3 is used to connect the drain board 1, so that when the insertion structure 2 is lifted, the bottom end of the drain board 1 is separated from the boot door 22 together with the sealing structure 3.

[0036] It should be noted that the drain board 1 is a strip-shaped drain board, and the drain board 1 can be made of plastic material, silicone material or environmentally friendly straw degradation material. When the drain board 1 is inserted into the insertion structure 2 from the top of the sheathing tube 21, a part of the strip-shaped plastic drain board 1 is inside the sheathing tube 21, and the other part of the structure is outside the sheathing tube 21. The boot door 22 can be a conical structure with a hollow interior and an opening at the bottom, so the vertical section of the boot door 22 is a triangular structure (see Figure 1 As shown), when the boot door 22 is installed at the bottom end of the sheathing tube 21, the boot door 22 is connected to the sheathing tube 21, so that the bottom end of the drain board 1 inserted into the sheathing tube 21 can extend into the boot door 22. Figure 1 and Figure 2 In order to show the entire vertically arranged casing pipe, Figure 1 and Figure 2 The sheath tube is cut to a certain extent to shorten the displayed length of the sheath tube, and it is indicated by double horizontal lines.

[0037] When the insertion structure 2 is inserted into the soil layer, the water inlet hole 211 is located at the water layer above the soil layer (see Figure 1 and Figure 6As shown), the water flow of the water layer above the soil layer can enter the insertion structure 2 from the water inlet hole 211. Since the entire drain board 1 is in the protective tube 21 and is not exposed to the outside of the boot door 22, the drain board 1 in the protective tube 21 will not be worn by the soil layer during the insertion of the insertion structure 2 into the soil layer, which accordingly plays a certain protective role for the drain board 1. When the insertion structure 2 is lifted, the water flow in the water flow channel of the insertion structure 2 can flush the drain board 1 out of the opening under the action of gravity. Therefore, the opening is not only conducive to the bottom end of the drain board 1 extending out and connecting with the sealing structure 3 outside the opening, but also conducive to the water flow in the water flow channel flowing downward to flow out from the opening, so as to flush the bottom end of the drain board 1 out of the opening of the boot door 22, and correspondingly prevent the silt of the soil layer from entering the boot door 22 from the opening in reverse.

[0038] The sealing structure 3 is used to have at least two states of positional relationship with the opening of the boot door 22. For example, when the insertion structure 2 is installed before being inserted into the soil layer, the sealing structure 3 needs to be sealed with the opening of the boot door 22 to seal the opening of the boot door 22, so as to ensure that the insertion structure 2 is effectively prevented from entering the boot door 22 from the opening of the boot door 22 during the insertion of the soil layer; when the drainage board 1 is inserted into the bottom elevation position of the soil layer through the insertion structure 2 and then lifted up, the sealing structure 3 can move downward under the action of the downward scouring of water in the water flow channel of the insertion structure 2 and the squeezing of the sealing structure 3 beyond the bottom width of the boot door 22 by the silt outside the boot door 22, so as to detach from the boot door 22.

[0039] The drain board insertion device in this embodiment mainly includes an insertion structure 2 and a sealing structure 3. Before the drain board 1 is inserted to the bottom elevation of the soil layer through the insertion structure 2, the drain board 1 needs to be connected to the sealing structure 3 first. For example, the strip-shaped drain board 1 is inserted from the top of the protective tube 21 in the insertion structure 2, extends into the protective tube 21 and extends downward to the boot door 22, and passes through the opening at the bottom end of the boot door 22 to connect with the sealing structure 3 under the boot door 22. Subsequently, a pulling force can be applied to the strip-shaped drain board 1 from the outside of the protective tube 21, so as to drive the sealing structure 3 to move upward to approach the boot door 22 by pulling the drain board 1, until the sealing structure 3 is sealed and connected to the opening of the boot door 22, thereby realizing the boot installation process.

[0040] Subsequently, the insertion structure 2 can be moved downwardly into the soil layer under the action of external force to bring the drainage board 1 in the insertion structure 2 to the bottom elevation position of the soil layer. In the process of the insertion structure 2 being inserted into the soil layer and bringing the drainage board 1 to the bottom elevation position, the sealing structure 3 is sealed with the bottom opening of the boot door 22, which can effectively prevent the silt in the soil layer from entering the boot door 22, and because the water inlet hole is in the water layer above the soil layer, the water flow in the water layer above the soil layer will also enter the inside of the casing pipe 21 from the water inlet hole 211 of the casing pipe 21, so that the water flow channel of the entire insertion structure 2 is filled with water, and the water flow in the insertion structure 2 can communicate with the ambient water outside the insertion structure 2.

[0041] When the insertion structure 2 is lifted up, the water flow inside the insertion structure 2 will flow downward under the action of gravity along the water flow channel formed by the sleeve pipe 21, the boot door 22 and the opening connected in sequence, not only flushing the bottom end of the drain board 1 out of the boot door 22 from the opening, but also the water flow can prevent the silt in the soil layer from reversely entering the boot door 22 from the opening. In this process, the silt around the bottom end of the drain board 1 separated from the boot door 22 will continuously squeeze the drain board 1 and the part of the sealing structure that exceeds the bottom width of the boot door to form silt resistance, and because the sealing structure 3 is connected to the bottom end of the strip-shaped drain board 1, the sealing structure 3 has a certain pulling force on the bottom end of the drain board 1, so that the drain board 1 and the sealing structure will accurately stay at the bottom elevation of the soil layer under the action of silt resistance, thereby effectively preventing the insertion structure 2 from driving the drain board 1 to move up a certain distance when lifted and causing the "back-draft" phenomenon, thereby ensuring the quality of the project.

[0042] In one embodiment of the present invention, Figure 2 and Figure 3 As shown, the sealing structure 3 includes a connecting portion 31 and a sealing portion 32. The sealing portion 32 is installed at the bottom end of the connecting portion 31. The connecting portion 31 is embedded in the boot door 22 from the opening and connected to the bottom end of the drainage board 1. The sealing portion 32 is sealed and connected to the opening.

[0043] It should be noted that the sealing portion 32 can be disposed below the connecting portion 31 , and the two can be an integrally formed structure, thereby effectively improving the mechanical strength of the sealing structure 3 and correspondingly extending the service life.

[0044] The bottom end of the drain board 1 can be connected to the connecting part 31 in the following manner. For example, before the insertion structure 2 enters the water layer, the bottom end of the drain board 1 moves downward and extends out of the opening of the boot door 22, and then the bottom end of the drain board 1 is connected to the connecting part 31. Then, a pulling force is applied to the drain board 1 outside the sheath pipe 21 to drive the sealing structure 3 to move upward by pulling the drain board 1 in the insertion structure 2, until the connecting part 31 of the sealing structure 3 is embedded in the boot door 22 from the opening, and the sealing part 32 is sealed and connected to the opening, thereby completing the boot installation operation.

[0045] in, Figure 1 , Figure 2 and Fig. 9 The drain board 1 in the inserted structure 2 is represented by a dotted line, which means that only a part of the length of the entire strip-shaped drain board 1 is in the inserted structure 2 and is blocked by the inserted structure 2. In other words, the drain board in the inserted structure 2 cannot be seen from the outside of the inserted structure 2, so the drain board 1 in the inserted structure 2 is represented by a dotted line.

[0046] In one embodiment of the present invention, the shape of the opening matches the shape of the portion of the sealing portion 32 facing the opening.

[0047] It should be noted that since the shape of the portion of the sealing portion 32 facing the opening matches the shape of the opening, the sealing performance between the sealing portion 32 and the opening of the boot door 22 can be further improved, effectively preventing silt in the soil layer from entering the boot door 22 from the connection between the opening and the boot door 22.

[0048] For example, the vertical cross-section of the opening may be a semicircular structure, the sealing portion 32 may be a sealing pin structure that matches the shape of the semicircular structure, and when the connecting portion 31 is connected to the bottom end of the drainage board 1, the sealing portion 32 of the sealing pin structure is in a horizontal state; when the sealing structure 3 moves upward to the boot door 22 during the boot installation operation, the sealing performance of the two can be further improved by increasing the contact area between the two.

[0049] In one embodiment of the present invention, Figure 3 As shown, the insertion structure 2 also includes a flexible connector 23, one end of the flexible connector 23 is connected to the side wall of the sheath tube 21 or the boot door 22, and the other end of the flexible connector 23 is connected to the sealing portion 32, and the sealing portion 32 is used to approach or move away from the boot door 22 through the flexible connector 23.

[0050] It should be noted that the flexible connector 23 is connected to the side wall of the sheath tube 21 or the boot door 22 to fix the flexible connector 23 on the insertion structure 2; the other end of the flexible connector 23 is connected to the sealing part 32 so that the sealing part 32 of the sealing structure 3 can be installed on the insertion structure 2 through the flexible connector 23.

[0051] The length of the flexible connector 23 is greater than the height between the upper end of the flexible connector 23 and the bottom end of the boot door 22. In other words, when the sealing structure 3 is sealed and connected to the opening of the boot door 22, the flexible connector 23 is in a relaxed state. The flexible connector 23 is a linear connector with a certain folding margin, such as a chain, a drawstring, etc., which is not specifically limited here.

[0052] After the insertion structure 2 inserts the drainage board 1 to the bottom elevation of the soil layer, the insertion structure 2 will perform an upward lifting movement, and the bottom end of the drainage board 1 and the sealing structure 3 will separate from the boot door 22. This process can be called a boot removal operation. When the insertion structure 2 continues to move upward to drive the flexible connector 23 to lift up, so that the top end of the flexible connector 23 is raised more than the length of the flexible connector 23, the flexible connector 23 can be in a tensioned state, which will drive the sealing structure 3 to separate from the bottom end of the drainage board 1, so that the bottom end position of the drainage board 1 is left at the bottom elevation, and the sealing structure 3 and the flexible connector 23 will rise with the sheath pipe 21, so that the designed length of the drainage board 1 can be retained in the soil layer, which can not only avoid the "back-draft" phenomenon of the drainage board 1, but also enable the sealing structure 3 to be reused.

[0053] In one embodiment of the present invention, Figure 3 As shown, the drainage board 1 is snap-connected with the connecting portion 31 .

[0054] It should be noted that, since the drain board 1 and the connection portion 31 are snap-fitted together, the assembly efficiency of the drain board 1 and the connection portion 31 can be improved.

[0055] In one embodiment of the present invention, Figure 3 and Figure 4 As shown, the connection portion 31 has a slot 311 , and the drainage board 1 in the boot door 22 has a bending portion 11 , and the bending portion 11 is engaged with the slot 311 .

[0056] It should be noted that, since the bending portion 11 is engaged with the engaging groove 311 , not only a quick engagement of the two is achieved, but also the connection stability of the two can be improved.

[0057] The connection portion 31 of the sealing structure 3 can be connected to the drain board 1 in the following manner, for example, the bottom end of the drain board 1 is first extended from the opening of the boot door 22, and then the bottom end of the drain board 1 is bent (for example, folded in half) to form a bent portion 11 (see Figure 3As shown in the figure, the bent portion 11 is then engaged with the slot 311 of the connecting portion 31, and then the drain board 1 can be lifted up from the outside of the protective tube 21 to drive the sealing structure 3 to move upward by pulling the drain board 1 until the connecting portion 31 of the sealing structure 3 is embedded in the boot door 22 from the opening. Since the drain board 1 is a strip-shaped plastic drain board with a certain elasticity, and the boot door 22 is a conical structure that gradually increases from the bottom to the top, when the bent portion 11 of the drain board 1 enters the boot door 22 from the bottom to the top, the bent portion 11 will produce a certain elastic recovery (i.e., expansion), and the expanded bent portion 11 will resist the inner wall of the boot door 22 to be stably engaged in the boot door 22. At this time, the bent portion 11 engaged with the connecting portion 31 can overcome the gravity of the sealing structure 3 itself, so that in the absence of external force, the sealing structure 3 will not drive the bottom end of the drain board 1 to separate downward from the boot door 22.

[0058] The slot 311 may be a "7"-shaped slot, and the bottom end of the drain board 1 may be folded in half and quickly pass through the "7"-shaped slot 311 to achieve a quick connection between the bent portion 11 of the drain board 1 and the slot 311 .

[0059] In one embodiment of the present invention, the inner wall of the boot door 22 near the sealing structure 3 has a smooth surface for reducing friction with the drainage board 1 .

[0060] It should be noted that a smooth surface is provided on the inner wall of the boot door 22 near the sealing structure 3 to prevent the bent portion 11 of the drain board 1 from being caught by the boot door 22 when the insertion structure 2 is lifted up after inserting the drain board 1 into the bottom elevation position of the soil layer, thereby ensuring that the insertion structure 2 can enable the bent portion 11 of the drain board 1 and the sealing structure 3 to smoothly detach from the boot door 22 downward when lifted (completing the boot removal operation).

[0061] In an embodiment of the present invention, the boot door 22 and the sheath tube 21 are an integrally formed structure.

[0062] It should be noted that since the boot door 22 and the casing pipe 21 are an integrally formed structure, it can not only ensure that the connection between the two meets the mechanical strength required for inserting downward into the soil layer, avoiding bending, deformation and other problems during the insertion into the soil layer, but also ensure the sealing of the two to prevent the water flow in the insertion structure 2 from leaking from the connection between the two when inserted into the bottom elevation position of the soil layer, thereby reducing the power to guide the drain board 1 out of the boot door 22, thereby ensuring that the drain board 1 can smoothly carry out the boot removal operation.

[0063] Combination Figure 5 , Figure 6 and Figure 8As shown, another embodiment of the utility model provides a plate insertion machine, including a drain board 1 and the drain board insertion device as described above, and also including a vibrating hammer 4, a reel 5, a first guide wheel structure 6 and a lifting device. The insertion structure 2 of the drain board insertion device is installed at the bottom end of the vibrating hammer 4, and the lifting device is connected to the vibrating hammer 4, and is used to drive the vibrating hammer 4 to drive the insertion structure 2 to move up and down; the first guide wheel structure 6 is installed at a position where the vibrating hammer 4 is close to the insertion structure 2, and the reel 5 is installed on one side of the lifting device. The reel 5 is used to wind the drain board 1, and the end of the drain board 1 away from the reel 5 bypasses the first guide wheel structure 6 and enters the insertion structure 2.

[0064] It should be noted that the insertion structure 2 is arranged below the vibrating hammer 4, and the top of the insertion structure 2 is connected to the vibrating hammer 4 to fix the insertion structure 2 to the bottom of the vibrating hammer 4. Since the lifting device is connected to the vibrating hammer 4, the vibrating hammer 4 can be driven to drive the insertion structure 2 to move up and down, so as to bring the drainage board 1 inserted in the insertion structure 2 to the bottom elevation of the soil layer. The first guide wheel structure 6 can be installed at the position of the vibrating hammer 4 close to the insertion structure 2, and the reel 5 is used to wind the strip-shaped drainage board.

[0065] The drain board 1 can enter the casing tube 21 of the insertion structure 2 in the following manner, for example, the reel 5 is rotated to unfold the drain board 1 wound on its upper part, and then the end of the unfolded drain board 1 bypasses the first guide wheel structure 6 and extends into the interior of the casing tube 21 from the top of the casing tube 21, and extends downward along the axial direction of the casing tube 21 to the position of the boot door 22, so as to enable the drain board 1 to be inserted into the insertion structure 2; therefore, the first guide wheel structure 6 is used for the end of the strip drain board 1 on the reel 5 to bypass so as to enter the interior of the casing tube 21, so the first guide wheel structure 6 can play the role of a fixed pulley.

[0066] Among them, Figure 5 In the figure, the drainage board 1 located outside the insertion structure 2 is indicated by a solid line.

[0067] In one embodiment of the present invention, Figure 5 , Figure 6 and Figure 8 As shown, the lifting device includes a winch structure 7, a rope structure 8, a pile frame 9 and a second guide wheel structure 10, the winch structure 7 is installed on one side of the pile frame 9, at least a portion of the second guide wheel structure 10 is installed on the pile frame 9, the rope structure 8 is wound around the winch structure 7, and one end of the rope structure 8 away from the winch structure 7 is wound around the second guide wheel structure 10 and connected to the vibratory hammer 4.

[0068] It should be noted that the winch structure 7 can be installed on one side of the pile frame 9, such as the right side, and the reel 5 can be installed on the other side of the pile frame 9, such as the left side. At least a portion of the second guide wheel structure 10 is installed on the pile frame 9, which can provide a guide for the rope structure 8. Part of the rope structure 8 is wound around the winch structure 7, and the end of the rope structure 8 away from the winch structure 7 can bypass the second guide wheel structure 10 and then connect with the vibratory hammer 4, so that the rising and falling actions of the vibratory hammer 4 can be realized by the winch structure 7 through the retraction and release of the rope structure 8.

[0069] The hoisting structure 7 may be a hoisting machine, and the rope structure 8 may be a steel wire rope.

[0070] At least part of the second guide wheel structure 10 is installed on the pile frame 9. It can be understood that if the second guide wheel structure 10 includes two second guide wheels, the two second guide wheels can be completely installed on the top of the pile frame 9, so that the rope structure 8 led out from the winch structure 7 can directly bypass the two second guide wheels set at the top of the pile frame 9 and then connect with the top of the vibrating hammer 4; if the second guide wheel structure 10 includes more than three second guide wheels, two of the second guide wheels can be installed at the top of the pile frame 9, and the other second guide wheels can be installed on the ground, so that the rope structure 8 led out from the winch structure 7 first bypasses the second guide wheel set on the ground, and then bypasses the second guide wheel at the top of the pile frame 9 and then connects to the top of the vibrating hammer 4, so as to realize the assembly operation of the winch structure 7 connecting the vibrating hammer 4 through the rope structure 8.

[0071] Combination Figures 5 to 9 As shown, the working steps for inserting the drainage board 1 into the bottom elevation position of the soil layer by inserting the structure 2 can refer to the following process:

[0072] First, the vibrating hammer 4 is at the highest position, and the bottom end of the boot door 22 in the insertion structure 2 is at a position above the water surface, which can be defined as the first position. Figure 5 As shown, the bottom end of the drain board 1 is connected to the connecting portion 31 of the sealing structure 3. Specifically, the strip-shaped drain board 1 on the reel 5 passes around the first guide wheel structure 6 and is inserted into the interior of the casing tube 21 from the top end of the casing tube 21 and extends downward to the boot door 22. Then, the boot door 22 continues to pass downward from the opening of the boot door 22, and the bent portion 11 of the drain board 1 is engaged with the slot 311 of the connecting portion 31. The bent portion 11 and the connecting portion 31 are inserted into the boot door 22 together, and a pulling force is applied to the drain board 1 from the outside of the casing tube 21 to drive the sealing structure 3 to move upward until the sealing portion 32 is sealed with the opening of the boot door 22 to complete the boot installation operation.

[0073] Secondly, combined Figure 6 and Figure 7 As shown, the winch structure 7 works to release the rope structure 8, so that the vibrating hammer 4 drives the insertion structure 2 to move downward and pass through the water surface in sequence (see Figure 6 The dotted line position indicated by s in the figure), soil surface (see Figure 6 The short solid line position indicated by t in the figure) until it sinks to the bottom elevation of the soil layer (see Figure 6 The long solid line position represented by h in the figure can be defined as the second position, wherein, after the insertion structure 2 enters the soil layer, the vibrating hammer 4 is started to vibrate the insertion structure 2, and the mud layer around the casing pipe 21 is vibrated and liquefied due to the vibration until the insertion structure 2 sinks to the bottom elevation position. During the process of the casing pipe 21 descending from the first position to the second position, the bent portion 11 of the drain plate 1 is clamped in the clamping groove 311 of the connecting portion 31 and is located in the boot door 22. The sealing portion 32 of the sealing structure 3 is sealed with the boot door 22, so that the silt in the soil layer cannot enter the casing pipe 21. When the boot door 22 at the bottom end of the casing pipe 21 is inserted to the bottom elevation position, the drain plate 1 is also sent into the bottom elevation position by the insertion structure 2. Since the multiple water inlet holes 211 of the casing pipe 21 are located in the water layer above the soil layer, the water flow in the water layer area above the soil surface can enter the interior of the casing pipe 21 from the water inlet holes 211, so that the interior of the insertion structure 2 is filled with water flow. Among them, since the water inlet holes 211 are in the water layer above the soil layer (in other words, the water inlet holes 211 are higher than the soil layer), it is ensured that only water flow can enter the water inlet holes 211, and the silt in the soil layer cannot enter the casing pipe 21 through the water inlet holes 211.

[0074] Furthermore, combined Figure 8 and Fig. 9 As shown, after the insertion structure 2 inserts the drain board 1 into the bottom elevation position of the soil layer, when the insertion structure 2 is driven to rise by the lifting device, one end of the flexible connector 23, for example the upper end, will rise with the sheathing pipe 21, and the water flow in the insertion structure 2 will, under the action of gravity, flush the bent portion 11 of the drain board 1 and the connecting portion 31 of the sealing structure 3 out of the boot door 22 (this process is called boot removal). At the same time, the silt around the drain board 1 continuously squeezes the bent portion 11 of the drain board 1 and the sealing portion 32 (for example, a sealing pin) beyond the bottom width of the boot door 22, forming silt resistance, and the water flow in the sheathing pipe 21 continuously flushes out of the boot door 22, preventing the silt from entering the sheathing pipe 21 while also allowing the drain board 1 to more smoothly detach from the sheathing pipe 21. In the process of the upper end of the flexible connector 23 being lifted to a height that reaches the length of the flexible connector 23, the sealing structure 3 and the bent portion 11 of the drain board 1 will always stay at the bottom elevation position (see Fig. 9), that is, the sealing structure 3 is in a static state; as the jacket tube 21 continues to be lifted up, when the upper end of the flexible connector 23 rises to a height exceeding the length of the flexible connector 23, the flexible connector 23 is in a tensioned state, which will drive the connection portion 31 of the sealing structure 3 to separate from the bottom bending portion 11 of the drainage board 1, so that the entire sealing structure 3 and the flexible connector 23 rise with the jacket tube 21, which not only accurately leaves the drainage board 1 of the designed length at the bottom elevation of the soil layer, avoiding the "back-draft" phenomenon, but also can bring back the sealing structure 3 through the flexible connector 23 to achieve the reuse of the sealing structure 3.

[0075] Finally, the insertion structure 2 can be lifted to the first position (i.e., the initial position) by the lifting action of the lifting device. At this time, the boot door 22 is at a certain distance from the water surface, for example, about 1.5 meters. The upper part of the drainage board 1 can be cut off at a certain distance from the soil surface, for example, about 20 centimeters, by manual or mechanical tools. Then, the above-mentioned boot installation operation is started again, and the work is continuously circulated according to the above steps, so as to realize the insertion of more strip-shaped drainage boards 1 into different areas of the soil layer.

[0076] Although the utility model is disclosed as above, the protection scope of the utility model is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will fall within the protection scope of the utility model.
