[0002] In order to solve the current shortage of construction land in my country, land reclamation is usually used to increase construction land. In engineering construction, silt is often used as a material for land reclamation. However, due to the extremely high water content of silt, it basically has no strength and needs to be treated with foundation to improve its bearing capacity and stability before subsequent engineering construction can be carried out.

[0003] The vacuum preloading method is often used in engineering to reinforce such high-water content silt foundations. The existing vacuum preloading method often uses vertical drain boards as drainage channels, but due to the large settlement of the soil during the treatment process, the drain boards are prone to bending, affecting the consolidation effect of the silt. In response to the above problems, it has been proposed to use horizontal drain boards combined with vacuum preloading to improve the silt foundation treatment effect, but the laying method of horizontal drain boards in silt foundation environments is extremely complicated and requires a lot of manpower. At the same time, the laying depth of the drain boards is limited, which has great limitations in construction. For this reason, it is necessary to design a horizontal drain board laying device that is more suitable for use in silt foundations, which is convenient and flexible to operate and has high precision, so as to solve the current problem of difficulty in laying horizontal drain boards in silt foundations.

[0038] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0039] Reference Figure 1-8 As shown, a first embodiment of the present invention provides an automatic laying device for a horizontal drain board with adjustable buoyancy, comprising a fuselage system, a propulsion system, a buoyancy adjustment system, a drain board system and a positioning system, wherein the propulsion system is installed at the bottom of the fuselage system, and the buoyancy adjustment system and the positioning system are arranged on the fuselage system. The propulsion system drives the fuselage system to move in a horizontal direction, and the positioning system locates and monitors the movement trajectory of the drain board. After reaching the set position, the buoyancy adjustment system drives the fuselage system to move in a depth direction, and the drain board system is installed at the rear end of the fuselage system. The end of the drain board system away from the fuselage system is connected to an external vacuum drainage device through a drainage pipe system. When the drain board system is laid to the set position, drainage and consolidation are carried out by starting an external vacuum pumping device.

[0040] The fuselage system includes a conical head 1, a body 2 and a plurality of crushing discs 5. A main motor 3 is provided at the front end of the inner cavity of the body 2. The main motor 3 is connected to the head 1 through a transmission rod 4. When the main motor 3 is started, the main motor 3 drives the head 1 to rotate through the transmission rod 4. The plurality of crushing discs 5 are evenly distributed on the outside of the head 1. A driving motor 6 is provided in the inner cavity of the head 1. The driving motor 6 is connected to the crushing disc 5 through a rotating rod 7. The driving motor 6 drives the crushing disc 5 to rotate through the rotating rod 7. The head 1 is a cone and can rotate, so that the device is subjected to less resistance when traveling in a soft mud foundation. The crushing disc 5 can crush the gravel on the path of the device when it travels, reduce resistance, and prevent gravel from hitting the head and causing damage to the device.

[0041] The buoyancy regulating system includes an inner oil bag 9, an outer oil bag 10 and a hydraulic oil transmission assembly. The inner oil bag 9 is arranged in the fuselage 2, and the outer oil bag 10 is arranged on the periphery of the fuselage 2. The inner oil bag 9 is connected to the outer oil bag 10 through the hydraulic oil transmission assembly. The hydraulic oil is transmitted between the inner oil bag 9 and the outer oil bag 10 through the hydraulic oil transmission assembly. When the hydraulic oil in the inner oil bag 9 is transmitted to the outer oil bag 10 through the hydraulic oil transmission assembly, the volume of the outer oil bag 10 increases, causing the buoyancy increasing device to float upward. When the hydraulic oil in the outer oil bag 10 is transmitted to the inner oil bag 9 through the hydraulic oil transmission assembly, the volume of the outer oil bag 10 decreases, causing the buoyancy reducing device to sink downward. When the hydraulic oil transmission assembly is closed, the device maintains a constant buoyancy.

[0042] The hydraulic oil transmission assembly includes a control motor 13, a reversing valve 14, a steering gear 15, a forward pipe 11 and a reverse pipe 12. The inner oil bag 9 is connected to the outer oil bag 10 on both sides through the forward pipe 11 and the reverse pipe 12. A reversing valve 14 is arranged between the forward pipe 11 and the reverse pipe 12. A steering gear 15 is arranged on the top of the reversing valve 14. The steering gear 15 is connected to the control motor 13 in the fuselage through a line. The control motor 13 drives the steering gear 15, and the steering gear 15 drives the reversing valve 14 to work, so as to realize the reversal or cut-off between the oil circuits of the forward pipe 11 and the reverse pipe 12, and the hydraulic oil will not flow through the pipe in the cut-off state. The buoyancy adjustment system and the hydraulic oil transmission assembly are reasonably designed, and the buoyancy control of the whole device can be realized relatively conveniently, so that the device can lay horizontal drainage boards 19 at different depths in the silt soft foundation.

[0043] The drainage board system includes a plurality of horizontal drainage boards 19 and a plurality of drainage board connection devices. The horizontal drainage boards 19 are installed at the rear end of the fuselage system through the drainage board connection devices. The end of the horizontal drainage board 19 away from the fuselage 2 is connected to the vacuum pumping device through the drainage pipe system. When the fuselage system lays the horizontal drainage board 19 to the set position, the vacuum pumping device on the shore is started to drain and consolidate. The drainage board connection device is a clamping part, which includes a first clamping rod 28 and a second clamping rod 29. The first clamping rod 28 and the second clamping rod 29 are centrally hinged. A clamping gasket 30 is provided at one end of the clamping rod exposed outside the fuselage. One end of the clamping rod set in the fuselage 2 is connected through an electric telescopic rod 31. The electric telescopic rod 31 is connected to the small motor 27 inside the fuselage 2. When the small motor 27 is powered on, the electric telescopic rod 31 contracts to make the other end of the clamping rod clamp the horizontal drainage board 19. When the small motor 27 is powered off, the electric telescopic rod 31 is reset to make the clamping rod release the horizontal drainage board 19 to complete the laying work.

[0044] The propulsion system 8 includes a water inlet pipe 801, a water jet pump 802, a water outlet pipe 803 and an electric remote control device 805. The water inlet pipe 801 is arranged at the water inlet end of the water jet pump 802. A filter screen 804 is arranged at the pipe mouth of the water inlet pipe 801. The water outlet pipe 803 is arranged at the water outlet end of the water jet pump 802. The top of the water jet pump 802 is connected to the bottom of the fuselage system, and an electric remote control device 805 is arranged to control the operation of the water jet pump 802. When the electric remote control device 805 is started, the water jet pump 802 sucks sludge from the front water inlet pipe 801 and sprays it from the rear water outlet pipe 803 to form a propulsion force to push the device to move. The water inlet pipe 801 is provided with a filter screen 804. When sucking sludge, larger impurities can be filtered through the filter screen 804 to avoid clogging the inside of the propulsion device 8 and affecting the work.

[0045] A GPS positioning module 17 is disposed on the upper end of the fuselage 2. The GPS positioning module 17 includes a navigation system, a remote sensing system and an information transmission system. The device information can be wirelessly transmitted to a computer through the GPS positioning module 17. The navigation system can plan the device's route, and the remote sensing system can remotely control the GPS positioning module 17 to transmit the device information through the transmission system.

[0046] According to the above-mentioned automatic laying device for horizontal drain boards with adjustable buoyancy, the present invention also provides a method for using the automatic laying device for horizontal drain boards with adjustable buoyancy, and the steps are as follows:

[0047] (1) One end of the horizontal drain board 19 is installed on the rear end of the body 2 of the horizontal drain board automatic laying device through a drain board connecting device. The drain board connecting device is a clamping part. The horizontal drain board 19 is placed between the clamping gaskets. After the small motor 27 is powered on, the first clamping rod 28 and the second clamping rod 29 are tightened to clamp the horizontal drain board 19 to connect it to the horizontal drain board automatic laying device. The other end of the horizontal drain board 19 is connected to a vacuum pumping device placed on the shore.

[0048] (2) The automatic laying device for horizontal drainage boards is placed on the mud foundation, the position of the horizontal drainage boards 19 is confirmed, and the route of the automatic laying device for horizontal drainage boards is planned through the function of the GPS positioning module 17.

[0049] (3) After determining the travel route, start the electric remote control device 805 of the propulsion system. The electric remote control device 805 controls the water pump 802 to start operation. The propulsion system sucks in sludge through the water inlet pipe 801. After the sludge is filtered out of larger impurities by the filter screen 804 at the mouth of the water inlet pipe, it enters the water pump 802. The water pump 802 sprays the filtered sludge to the outside through the water outlet pipe 803. Under the reaction force of the water flow, the horizontal drainage board automatic laying device provides propulsion force, causing it to start moving along the planned route.

[0050] (4) When the automatic laying device for horizontal drain boards deviates from the original route or arrives at the set position, it is necessary to adjust the buoyancy of the automatic laying device for horizontal drain boards. By adjusting the hydraulic oil content in the inner and outer oil bags 10 in the buoyancy adjustment system, the volume of the fuselage system is changed, thereby changing the buoyancy of the entire automatic laying device for horizontal drain boards. The control motor 13 in the hydraulic oil transmission component is turned on, and the control motor 13 drives the steering gear 15. The steering gear 15 drives the reversing valve 14 to change the conduction state of the forward pipe 11 and the reverse pipe 12, so that the hydraulic oil content in the outer oil bag 10 and the inner oil bag 9 changes, thereby realizing the buoyancy adjustment of the automatic laying device for horizontal drain boards and changing the diving depth of the automatic laying device for horizontal drain boards in high-water content sludge.

[0051] (5) The GPS positioning module 17 transmits the positioning signal to the computer in real time through the transmission system to monitor whether the horizontal drain board 19 has reached the set position. When the automatic laying device of the horizontal drain board reaches the set position, the automatic laying device of the horizontal drain board is separated from the horizontal drain board 19 through the drainage board detachment device to complete the laying of the horizontal drain board 19. Then, the buoyancy adjustment system is used to reduce the volume of the outer oil bag 10 so that the automatic laying device of the horizontal drain board floats up and away from the consolidation area. Then, the computer system starts the vacuum pumping device to drain and consolidate.

[0052] After adopting the above technical scheme, the automatic laying device for horizontal drainage boards is placed in the silt soft foundation where the horizontal drainage boards need to be laid. The silt is filtered through the filter 804 through the water inlet pipe 801 at the bottom of the propulsion device 8, and then sucked into the water spray pump 802. The water spray pump 802 sprays the silt from the outlet pipe 803. The reaction force of the injection is used to enable the automatic laying device for horizontal drainage boards to move in the silt soft foundation. When the device moves, the main motor 3 and the drive motor 6 respectively control the rotation of the machine head 1 and the crushing disc 5. The crushing disc 5 crushes stones to reduce the resistance of the device when it moves. The precise route is determined according to the GPS positioning module 17 on the top of the automatic laying device for horizontal drainage boards, and the route is wirelessly transmitted to the computer.

[0053] When the confirmation device reaches the set position, the hydraulic oil content in the inner oil bag 9 and the outer oil bag 10 is transmitted to each other through the hydraulic oil transmission component through the buoyancy adjustment system. When the device needs to sink, the control motor 13 in the hydraulic oil transmission assembly is turned on, and the steering gear 15 controls the reversing valve 14 to open the reverse pipe 12, so that the reverse pipe 12 is in a conducting state, and the hydraulic oil in the outer oil bag 10 is transmitted to the inner oil bag 9 through the reverse pipe 11, the volume of the outer oil bag 10 is reduced, and the buoyancy is reduced, causing the device to sink. When the device needs to float, the control motor 13 in the hydraulic oil transmission assembly is turned on, and the steering gear 15 controls the reversing valve 14 to open the forward pipe 11, and the forward pipe 11 is in a conducting state. The hydraulic oil in the inner oil bag 9 is transmitted to the outer oil bag 10 through the forward pipe 12, and the volume of the outer oil bag 10 is increased, and the buoyancy is also increased, causing the device to float, and the control motor 13 of the hydraulic oil transmission assembly is turned off. At this time, the forward pipe 11 and the reverse pipe 12 are both in a closed state, and the hydraulic oil content in the inner oil bag 9 and the outer oil bag 10 remains unchanged, so that the buoyancy is constant, and the device will be stable in the set position.

[0054] After the device is stabilized at the set position, the power supply of the small motor 27 is cut off to reset the electric telescopic rod 31, and the clamping part releases the horizontal drain board 19, and the horizontal drain board 19 is separated from the automatic laying device of the horizontal drain board to complete the laying. The horizontal drain board 19 is connected to the vacuum pumping device on the shore to drain and consolidate. This automatic laying device for horizontal drain boards with adjustable buoyancy can move more flexibly in silt soft foundations, and can achieve laying work at different depths through the buoyancy adjustment system, reducing the limitations brought by the construction environment. In the GPS positioning module, the navigation system can plan the route of the device, and the remote sensing system can remotely control the GPS positioning module 17, transmit the device information through the transmission system, and use the GPS module to enable the device to be remotely controlled and the route to be planned, thereby reducing the input of manpower and material resources, reducing construction costs, and improving construction efficiency.

The inner diameter of the fixing hoop 23 is adjusted by the connecting rod 24, so that the fixing hoop 23 can clamp the end of the horizontal drain board 19 and fix it, thereby preventing the drainage board from being deformed when it is laid, thereby affecting the construction. The two fixing hoop 23 are connected by inserting the connecting rod 24, so that they can be used to fix horizontal drain boards 19 of different widths, thereby improving the applicability of the drainage board fixing assembly.

[0059] After adopting the above technical scheme, when preparing for the construction of the automatic laying device for horizontal drain boards, confirm the laying position of the drain boards, adjust the width of the fixing seat 21 to match the width of the horizontal drain boards 19, and install it at a suitable position on the fixed base plate 20 through a threaded connection, so as to realize the spacing setting when laying the horizontal drain boards 19, connect it with the horizontal drain boards 19 through the hook group 18 on the fixing seat 21, adjust the length of the support rod 22 so that the fixed hoop 23 on the support rod 22 can be at the end of the horizontal drain board 19, insert the fixed hoop 23 through the connecting rod to connect, limit the deformable space at the end of the drain board, thereby preventing the laid drain board from deforming, and the drain board fixing assembly adopts an adjustable design on each component, so that the drain board fixing assembly can be used for drain boards of different sizes, and has better applicability. After the automatic laying device of the horizontal drainage board reaches the set position, the pawl 25 is deflected outward by turning on the power of the small motor, so that it no longer bites the ratchet teeth 26 of the fixed base plate 20. At this time, the fixed base plate 20 is no longer restricted by the pawl 25 and is separated from the fuselage 2, thereby completing the laying. The drainage board fixing and adjusting device on the fixed base plate 20 can still limit the deformation of the drainage board, thereby ensuring the construction quality of the subsequent drainage consolidation link.
