Description

Technical Field

[0001] The present invention belongs to the technical field of highway engineering construction, and particularly relates to a soft foundation reinforcement device for highway engineering construction. Background Art

[0002] A soft soil foundation refers to a weak soil layer with low strength and high compressibility, and most of them contain a certain amount of organic matter. Due to the low strength and large settlement of soft soil, it often causes great harm to road engineering. If not properly treated, it will have a great impact on the construction and use of highways.

[0003] The traditional mechanical rolling type soft soil foundation reinforcement device reinforces the soft soil foundation by rolling with a road roller, but it is difficult to drain the groundwater in the soft soil foundation, resulting in poor reinforcement effect of the soft soil foundation. Therefore, it is necessary to set up sand wells in advance to seep out the water in the soft soil foundation, but the seepage time is long, delaying the construction period. Therefore, it is necessary to improve the existing soft soil foundation reinforcement device. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a soft soil foundation reinforcement device for highway engineering construction, which can reduce the water seepage time in the soft soil foundation and further reinforce the soft soil foundation by rolling with a road roller.

[0005] The technical solution of the present invention includes a vehicle carrier and a road roller. The road roller is arranged at the rear of the vehicle carrier. A drainage device is provided at the front of the vehicle carrier. The drainage device is connected to the vehicle carrier through a lifting component, and the lifting component drives the drainage device to move up and down. The drainage device includes a water collecting tank and a spiral component. The water collecting tank is connected to the lifting component. The spiral component includes a first motor, a spiral rod and a sleeve. The spiral rod is inserted into the sleeve, and the lengths of the spiral rod and the sleeve are the same. The first motor is located above the water collecting tank and is arranged at one end of the sleeve. The transmission shaft of the first motor is connected to the spiral rod to drive the spiral rod to rotate in the sleeve. The other end of the sleeve passes through the water collecting tank in the height direction. Filter holes are provided on the side wall of the sleeve below the water collecting tank to allow the water in the soft soil foundation to flow into the sleeve. Water outlet holes are provided on the side wall of the sleeve inside the water collecting tank to allow the water to be transmitted into the water collecting tank when the spiral rod rotates.

[0006] Further, a pressurizing component is provided in the water collecting tank. The pressurizing component includes a gravity block, a sliding rod, and two driving components. The sliding rod is located in the water collecting tank, and both ends of the sliding rod are connected to the upper end surface and the lower end surface of the water collecting tank respectively. The gravity block is slidably connected to the sliding rod. Rack teeth are provided on two opposite side walls of the gravity block. The two driving components are respectively located on both sides of the gravity block, and both driving components include a transmission rod and a second motor. The transmission rods are respectively rotatably connected to two opposite side walls of the water collecting tank. An incomplete gear is provided on the transmission shaft. The incomplete gear is meshed with the rack teeth at the corresponding position for transmission. The second motor is arranged outside the water collecting tank, and the second motor is connected to the transmission shaft to drive the transmission shaft to rotate, so as to drive the gravity block to move upward through the incomplete gear. When the incomplete gear rotates to the toothless part, the gravity block freely falls to hit the lower end surface of the water collecting tank under the action of gravity, thereby extruding the soft soil foundation.

[0007] Further, the pressurizing component includes a spring. The spring is located between the gravity block and the upper end surface of the water collecting tank, and the spring is sleeved on the sliding rod.

[0008] Further, there are at least two pressurizing components. The incomplete gears on the two transmission shafts are both at least two, and the number of incomplete gears on each transmission shaft is equal to the number of gravity blocks.

[0009] Further, a water storage device is provided on the water collecting tank. The water storage device includes a water pipe, a water pump, and a water storage tank. The water storage tank is arranged above the water collecting tank. One end of the water pipe is located below the interior of the water collecting tank, and the other end of the water pipe extends into the water storage tank. The water pump is arranged on the water pipe to transfer the water in the water collecting tank to the water storage tank.

[0010] Further, a one-way baffle is provided at the bottom of the sleeve, and the one-way baffle prevents soft soil from entering the sleeve.

[0011] Further, there are at least two spiral components.

[0012] Further, a crushed stone box is provided above the water collecting tank. The side wall of the crushed stone box is connected to the lifting component. The bottom of the crushed stone box is communicated with the sleeve located above the water collecting tank, so that the crushed stone in the crushed stone box enters the sleeve.

[0013] The technical solution provided by the embodiment of the present invention has the following advantages compared with the prior art:

[0014] The vehicle of the present invention drives the water collecting tank to descend through a lifting component, and the sleeve gradually inserts into the soft soil foundation. The lifting component continues to drive the water collecting tank to move downward, and the water collecting tank squeezes the soft soil foundation, enabling the water in the soft soil foundation to quickly seep into the sleeve through the filter holes. Then, the first motor drives the screw rod to rotate, pumping the water at the bottom of the sleeve upward and entering the water collecting tank through the water outlet holes. Finally, it is rolled by the road roller. Compared with the prior art, the present invention speeds up the water seepage time of the soft soil foundation and effectively strengthens the soft soil foundation through rolling by the road roller.

[0015] Other advantages, objectives, and features of the present invention will be partially reflected by the following description and partially understood by those skilled in the art through the research and practice of the present invention. Brief Description of the Drawings

[0025] The following will combine with the accompanying drawings to describe in detail a specific embodiment of the present invention. However, it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0026] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the technical solution of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0027] In the description of the embodiments of the present invention, unless otherwise specified, the meaning of "a plurality" refers to two or more.

[0028] As Figures 1 to 6 shown, the present invention provides a soft foundation reinforcement device for highway engineering construction, including a carrier 1 and a road roller 2. The road roller 2 is arranged at the rear of the carrier 1. A drainage device is provided at the front of the carrier 1. The drainage device is connected to the carrier 1 through a lifting member 3. The lifting member 3 drives the drainage device to move up and down. The drainage device includes a water collection tank 4 and a spiral assembly. The water collection tank 4 is connected to the lifting member 3. The spiral assembly includes a first motor 5, a spiral rod 6 and a sleeve 7. The spiral rod 6 is inserted into the sleeve 7, and the length of the spiral rod 6 is the same as that of the sleeve 7. The first motor 5 is located above the water collection tank 4, and the first motor 5 is arranged at one end of the sleeve 7. The transmission shaft 12 of the first motor 5 is connected to the spiral rod 6 to drive the spiral rod 6 to rotate in the sleeve 7. The other end of the sleeve 7 passes through the water collection tank 4 in the height direction. Filter holes are provided on the side wall of the sleeve 7 below the water collection tank 4, and the filter holes enable the water in the soft foundation to flow into the sleeve 7. Water outlet holes 8 are provided on the side wall of the sleeve 7 inside the water collection tank 4, and the water outlet holes 8 enable the water to be transmitted into the water collection tank 4 when the spiral rod 6 rotates.

[0029] The carrier 1 of the present invention drives the water collection tank 4 to descend through the lifting member 3, and the sleeve 7 gradually inserts into the soft foundation. The lifting member 3 continues to drive the water collection tank 4 to move downward. The water collection tank 4 squeezes the soft foundation, so that the water in the soft foundation quickly seeps into the sleeve 7 through the filter holes. Then the first motor 5 drives the spiral rod 6 to rotate, pumps the water at the bottom of the sleeve 7 upward, and enters the water collection tank 4 through the water outlet holes 8. Finally, it is rolled by the road roller 2, which speeds up the water seepage time of the soft foundation and effectively reinforces the soft foundation through the rolling of the road roller 2.

[0030] It can be understood that when there is water in the water collecting tank 4, the weight of the water collecting tank 4 can be increased, thereby increasing the acting force of the water collecting tank 4 on the soft soil foundation.

[0031] It should be noted that the lifting component 3 is a prior art, and the present invention will not elaborate on it in detail.

[0032] As Figure 3 and Figure 4 shown, in the embodiment provided by the present invention, a pressure increasing component is provided in the water collecting tank 4. The pressure increasing component includes a gravity block 9, a sliding rod 10 and two driving components. The sliding rod 10 is located in the water collecting tank 4, and both ends of the sliding rod 10 are respectively connected to the upper end surface and the lower end surface of the water collecting tank 4. The gravity block 9 is slidably connected to the sliding rod 10. Rack teeth 11 are provided on two opposite side walls of the gravity block 9. The two driving components are respectively located on both sides of the gravity block 9, and both driving components include a transmission rod and a second motor 14. The transmission rods are respectively rotatably connected to two opposite side walls of the water collecting tank 4. An incomplete gear 13 is provided on the transmission shaft 12. The incomplete gear 13 is in meshing transmission with the rack teeth 11 at the corresponding position. The second motor 14 is arranged outside the water collecting tank 4, and the second motor 14 is connected to the transmission shaft 12 to drive the transmission shaft 12 to rotate, so as to drive the gravity block 9 to move upward through the incomplete gear 13.

[0033] Working principle: When the second motor 14 is started to drive the rotating shaft to rotate, the gravity block 9 is driven to rise through the incomplete gear 13. When the incomplete gear 13 moves to the toothless part, the gravity block 9 freely falls to hit the lower end surface of the water collecting tank 4 under the action of gravity, thereby applying an impact force to the soft soil foundation and further improving the seepage rate of the soft soil foundation.

[0034] In the embodiment provided by the present invention, the pressure increasing component includes a spring 15. The spring 15 is located between the gravity block 9 and the upper end surface of the water collecting tank 4, and the spring 15 is sleeved on the sliding rod 10.

[0035] It can be understood that the function of setting the spring 15 is to increase the acting force when the gravity block 9 falls downward, so that the gravity block 9 has a stronger impact force.

[0036] It should be noted that due to the impact of the gravity block 9, the water collecting tank 4 vibrates. Therefore, shock absorption structures are provided at the connection of the lifting component 3, the connection of the first motor 5 and the sleeve 7, and the connection of the transmission shaft 12 and the water collecting tank 4 to prevent the lifting component 3, the first motor 5 and the second motor 14 from being damaged. The shock absorption structure is a prior art, and the present invention will not describe it.

[0037] In the embodiment provided by the present invention, there are at least two pressure increasing components. The incomplete gears 13 on the two transmission shafts 12 are both at least two, and the number of the incomplete gears 13 on each transmission shaft 12 is equal to the number of the gravity blocks 9.

[0038] It can be understood that when there are multiple pressurizing components arranged in a row, the gears on the same side of the gravity block 9 can share a transmission shaft 12 and a second motor 14, and only need to set multiple incomplete gears 13 on the transmission shaft 12. When there are multiple pressurizing components arranged in multiple rows, multiple driving components need to be set, and the number of driving components is twice the number of rows.

[0039] It can be understood that the gravity blocks 9 of multiple pressurizing components fall synchronously, which can increase the acting area and improve the impact force.

[0040] In the embodiment provided by the present invention, a water storage device is provided on the water collecting tank 4. The water storage device includes a water pipe 16, a water pump 17 and a water storage tank 18. The water storage tank 18 is arranged above the water collecting tank 4. One end of the water pipe 16 is located below the interior of the water collecting tank 4, and the other end of the water pipe 16 extends into the water storage tank 18. The water pump 17 is arranged on the water pipe 16 to transfer the water in the water collecting tank 4 to the water storage tank 18.

[0041] It can be understood that when there is more water in the water collecting tank 4, it will affect the acting force of the gravity block 9 on the lower end face of the water collecting tank 4, thereby reducing the acting force on the soft soil foundation. Therefore, it is necessary to drain the water in the water collecting tank 4 to avoid affecting the gravity block 9. Therefore, the water is transferred to the water storage tank 18 through the water pump 17 and the water pipe 16.

[0042] It can be understood that the water storage tank 18 is arranged above the water collecting tank 4, without storing water elsewhere, and does not reduce the pressure of the water collecting tank 4 on the soft soil foundation.

[0043] As Figure 5 shown, in the embodiment provided by the present invention, a one-way baffle 19 is provided at the bottom of the sleeve 7, and the one-way baffle 19 prevents soft soil from entering the sleeve 7.

[0044] It can be understood that the function of setting the one-way baffle 19 is to prevent soft soil from entering the sleeve 7, so as to transfer the soft soil to the water collecting tank 4. Otherwise, after a long time, the water collecting tank 4 will be full of soft soil, affecting the storage of water and the falling of the gravity block 9.

[0045] In the embodiment provided by the present invention, there are at least two screw components.

[0046] It can be understood that when multiple screw components are set, the acting area can be enlarged and the efficiency of engineering drainage can be improved.

[0047] In the embodiment provided by the present invention, a gravel box 20 is provided above the water collecting tank 4. The side wall of the gravel box 20 is connected to the lifting component 3, and the bottom of the gravel box 20 is communicated with the sleeve 7 located above the water collecting tank 4, so that the gravel in the gravel box 20 enters the sleeve 7.

[0048] It can be understood that after the drainage is completed, the lifting component 3 drives the water collection tank 4 to rise, causing the sleeve 7 to rise, and deep holes to appear in the soft soil foundation due to the action of the sleeve 7. The crushed stones in the crushed stone box 20 can be transported into the deep holes to further reinforce the soft soil foundation.

[0049] The transportation of crushed stones and the pumping of water in the soft soil foundation into the water collection tank 4 share a single screw assembly. Specifically:

[0050] When the water collection tank 4 moves downward, it is necessary to pump the water in the soft soil foundation at this time. At this time, the motor drives the screw rod 6 to rotate forward to pump the water in the sleeve 7 into the water collection tank 4.

[0051] After the pumping is completed, the water collection tank 4 moves upward. At this time, it is necessary to transport the crushed stones in the crushed stone box 20 into the deep holes extruded by the sleeve 7. At this time, the motor drives the screw rod 6 to rotate in reverse to transport the crushed stones into the deep holes.

[0052] In the embodiment provided by the present invention, a switching valve can be provided between the sleeve 7 and the crushed stone box 20. When it is necessary to transport the crushed stones, the switching valve is opened, otherwise it is in a closed state to avoid affecting the pumping of the screw assembly.

[0053] It should be noted that in this article, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including that element.

[0054] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily achieved. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to the specific details and the illustrated examples here.
