Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0035] Reference Figures 1 to 3 In an embodiment of the present invention, a roadbed improvement device is proposed, comprising a base 100, a first chemical liquid supply device 210 and a ground drilling device 300. The base 100 is connected with a material blocking member 800, and the base 100 is provided with a first cavity 110 on one side of the material blocking member 800, and the first cavity 110 is connected to the upper and lower sides of the base 100; the first chemical liquid supply device 210 is connected to the base 100, and the first chemical liquid supply device 210 is located above the first cavity 110, and the first chemical liquid supply device 210 is used to inject chemical liquid into the first cavity 110; the first chemical liquid supply device 210 is located above the ground drilling device 300. Between the material blocking member 800, the ground drilling device 300 includes a drill body 310 and a drill bit 330. The drill body 310 is connected to the base 100. The drill body 310 is used to drive the drill bit 330 to rotate and move in the up and down directions. A drill hole 160 is opened on the base 100. The drill bit 330 passes through the drill hole 160. The drill body 310 is connected to the base 100. The material blocking member 800 can make the roadbed soil drilled by the drill bit 330 move from both sides of the drill bit 330 to the middle.

[0036] The use process of the roadbed improvement device in the embodiment of the present invention is as follows: the roadbed improvement device is towed at the end where the drill bit 330 is located to move the roadbed improvement device along a set path, and the ground drilling device 300 drills the ground to a set depth. As the roadbed improvement device moves, a trench appears on the ground. The first chemical liquid supply device 210 injects chemical liquid into the trench. At the same time, the roadbed soil is dispersed to both sides of the trench under the rotation of the drill hole. The material blocking member 800 can gather the roadbed soil on both sides of the trench to the middle during the movement of the roadbed improvement device, so that the roadbed soil on both sides of the trench falls into the trench, thereby completing the burial of the soil.

[0037] The first chemical liquid supply device 210 may be a liquid container provided with a pump, through which the chemical liquid is injected into the first cavity 110. The first chemical liquid supply device 210 may also be a liquid container provided with a valve, through which the chemical liquid is injected into the first cavity 110 by switching the valve on and off. The first chemical liquid supply device 210 may also be other liquid containers that inject chemical liquid into the first cavity 110 by pressure injection. The material blocking member 800 may be set to an eight-shaped shape or other shapes that contract from both ends to the middle, so that the roadbed soil drilled by the drill bit 330 moves from both sides of the drill bit 330 to the middle.

[0038] The chemical liquid supplied by the first chemical liquid supply device 210 in the embodiment of the present application is a chemical liquid that can react chemically with soil particles to generate a gelling substance, so that the soil particles are combined and the strength of the soil body is improved. The ground drilling device 300 in the embodiment of the present application can be a drilling rig equipment used for drilling holes in the relevant technical field. A motor is arranged inside the drill body 310, and the motor drives the drill bit 330 to rotate so that the drill bit 330 drills the ground. The drill body 310 is driven to move in the up and down directions by a motor driving a screw transmission mechanism; it can also be achieved by driving the drill bit 330 through a driving member such as a cylinder or a hydraulic cylinder.

[0039] In the roadbed improvement device in the embodiment of the present invention, the first chemical liquid supply device 210 can inject chemical liquid into the roadbed, and a material stopper 800 is provided at one end of the first cavity 110 on the base 100. The material stopper 800 can make the roadbed soil material drilled by the drill bit 330 move from both sides of the drill bit 330 to the middle, so that the roadbed soil material falls into the trench, completing the soil material burial. The roadbed improvement device in the embodiment of the present invention can bury the soil material while injecting chemical solution into the roadbed soil, reducing the operations that construction personnel need to perform on the roadbed improvement, and can effectively improve the construction efficiency of the roadbed improvement.

[0040] Reference Figure 1 and Figure 2 In some embodiments of the present invention, the base 100 is provided with a second cavity 120 on a side of the material stopper 800 away from the earth drilling device 300, the first cavity 110 is connected with the second cavity 120, and the first cavity 110 and the second cavity 120 are located on both sides of the material stopper 800. The roadbed improvement device further includes a second chemical liquid supply device 220, the first chemical liquid supply device 210 is located above the first cavity 110, the second chemical liquid supply device 220 is located above the second cavity 120, and the second chemical liquid supply device 220 is used to inject chemical liquid into the second cavity 120, and the first cavity 110 is located between the second cavity 120 and the drill bit 330. The first cavity 110 and the second cavity 120 are connected in a manner that a connecting port is provided on the material stopper 800, or a gap is provided between the material stopper 800 and the material stopper 800.

[0041] It can be understood that the ground drilling device 300, the first cavity 110, and the second cavity 120 are arranged in sequence. During the process of pulling the roadbed improvement device at the end where the drill bit 330 is located, the drill bit 330 drills a trench on the roadbed, and the first chemical liquid supply device 210 behind the drill bit 330 injects chemical liquid into the trench once. The material blocking member 800 behind the first chemical liquid supply device 210 pushes the roadbed soil on both sides of the trench into the trench. The second chemical liquid supply device 220 behind the material blocking member 800 can inject chemical liquid into the roadbed soil buried in the trench once, so that the buried roadbed soil condenses. Therefore, the roadbed improvement device in this embodiment can perform two chemical liquid injections in succession during the movement of the roadbed improvement device, without the need for construction personnel to repeat construction, which effectively improves construction efficiency.

[0042] In addition, the chemical liquid in the first cavity 110 is injected into the roadbed. In order to ensure that the collapsible loess in the roadbed reacts fully, the chemical liquid must be in sufficient dosage. Therefore, the injection amount of the first chemical liquid supply device 210 will be set to the amount required for the excess collapsible loess in the roadbed. The first cavity 110 is connected to the second cavity 120, and the excess chemical liquid can enter the second cavity 120 and then be injected into the buried soil from the second cavity 120, thereby preventing the chemical liquid from overflowing from the first cavity 110 and saving the use of chemical liquid.

[0043] In some embodiments of the present invention, the material blocking member 800 includes a first baffle 130 and a second baffle 140, wherein the first baffle 130 is connected to one inner wall of the base 100, and the second baffle 140 is connected to the other inner wall of the base 100, and the distance between the first baffle 130 and the second baffle 140 decreases from the proximal end to the distal end relative to the drill bit 330. Since the distance between the first baffle 130 and the second baffle 140 decreases from the proximal end to the distal end relative to the drill bit 330, during the movement of the roadbed improvement device, the first baffle 130 and the second baffle 140 will gather the roadbed soil on both sides of the trench to the middle, so that the roadbed soil on both sides of the drill bit 330 falls into the trench.

[0044] In some embodiments of the present invention, the connection angle between the first baffle 130 and the base 100 is adjustable, and the connection angle between the second baffle 140 and the base 100 is adjustable. When the connection angle between the first baffle 130 and the base 100 changes, the distance between the first baffle 130 and the second baffle 140 will also change. The larger the distance between the first baffle 130 and the second baffle 140, the better the gathering effect of the roadbed soil on both sides of the trench, and the greater the amount of soil entering the trench on the roadbed. Therefore, the amount of soil buried in the roadbed trench by the roadbed improvement device can be changed by changing the connection angle between the first baffle 130 and the base 100 or the connection angle between the second baffle 140 and the base 100.

[0045] The connection angle between the first baffle 130 and the base 100 can be adjusted in a manner that: the first baffle 130 is hinged to the base 100, and the first baffle 130 can rotate relative to the base 100, thereby changing the connection angle between the first baffle 130 and the base 100. The connection angle between the first baffle 130 and the base 100 can also be adjusted in a manner that: the first baffle 130 and the base 100 are connected by threads, so that the first baffle 130 can be removed from the base 100 and then reconnected at a new angle. The connection angle between the second baffle 140 and the base 100 bracket can be adjusted in the same manner.

[0046] In some embodiments of the present invention, the first baffle 130 is connected to the base 100 by threads, and the second baffle 140 is connected to the base 100 by threads. The threaded connection is easy to install and disassemble, and has good stability, which can prevent the first baffle 130 and the second baffle 140 from loosening during the movement of the roadbed improvement device. The first baffle 130 and the base 100 are connected by threads in a manner that a through hole or a threaded hole is provided on the first baffle 130, and a through hole or a threaded hole is provided on the base 100, and the first baffle 130 and the base 100 are connected by bolts or screws. The second baffle 140 and the base 100 are connected in the same manner.

[0047] Reference Figure 1 In some embodiments of the present invention, screw rods 340 are respectively arranged on both sides of the drill body 310, and the two screw rods 340 are symmetrical about the drill body 310. A threaded sleeve bracket 350 is arranged between the two symmetrically arranged screw rods 340, and the screw rods 340 are connected to the base 100. The threaded sleeve bracket 350 is respectively threadedly connected to the two screw rods 340. A bracket hole (not shown in the figure) is opened on the threaded sleeve bracket 350, and the drill bit 330 passes through the bracket hole and the drill hole 160 in sequence, and the drill body 310 is connected to the threaded sleeve bracket 350. The threaded sleeve bracket 350 is respectively threadedly connected to the two screw rods 340, so that the position of the threaded sleeve on the two screw rods 340 can be adjusted. The drill body 310 is connected to the threaded sleeve bracket 350, so that the position of the drill body 310 changes with the change of the position of the adjusted threaded sleeve. Therefore, by adjusting the position of the threaded sleeve bracket 350 on the two screw rods 340, the height position of the drill body 310 can be adjusted to adapt to roadbeds of different heights. In addition, the two screw rods 340 arranged symmetrically can reduce the vibration caused by the drill bit 330 and improve the stability of the drill bit 330 when drilling.

[0048] The screw rod 340 and the base 100 may be connected by welding, threaded connection, etc. For example, in one embodiment of the present invention, the base 100 is provided with a screw rod mounting hole 170, and the screw rod mounting hole 170 is provided with an internal thread, and the screw rod 340 can be fixed in the screw rod mounting hole 170 by screwing.

[0049] Reference Figure 1 In some embodiments of the present invention, a first fixing member 360 is provided on the base 100, and the drill body 310 is connected to a limiting ring 320, which is sleeved on the first fixing member 360 and can move up and down along the first fixing member 360. The limiting ring 320 is nested with the first fixing member 360 to reduce the displacement movement of the drill body 310 caused by the vibration of the drill bit 330. The limiting ring 320 can be matched with the first fixing member 360 through clearance, so as to be able to move up and down along the first fixing member 360.

[0050] Reference Figure 1 and Figure 4 In some embodiments of the present invention, the roadbed improvement device further includes a smoothing mechanism 400, which is located on the side of the material blocking member 800 away from the ground drilling device 300. The smoothing mechanism 400 includes a smoothing roller 410, a smoothing roller shaft 420 and a mounting seat 430. The mounting seat 430 is connected to the base 100, and the smoothing roller shaft 420 is connected to the mounting seat 430. The smoothing roller 410 is sleeved on the smoothing roller shaft 420 and can rotate around the smoothing roller shaft 420. The smoothing roller 410 is used to smooth the road surface. After the material blocking member 800 gathers the roadbed soil into the trench, the smoothing mechanism 400 can smooth the uneven roadbed soil on the roadbed surface to make the roadbed surface flat. The construction personnel can inject chemical liquid into the roadbed soil and bury it through the roadbed improvement device in this embodiment, and at the same time, smooth the roadbed surface, which effectively improves the construction efficiency of the roadbed improvement.

[0051] It is understandable that, referring to Figure 1 In an embodiment in which the roadbed improvement device is provided with a first cavity 110 and a second cavity 120, the smoothing mechanism 400 is located on a side of the material blocking member 800 away from the ground drilling device 300. The smoothing mechanism 400 can be arranged to be located behind the second cavity 120, so that after the second chemical liquid supply device injects chemical liquid into the trench, the smoothing mechanism 400 can smooth the soil on the surface of the roadbed to ensure that the surface of the roadbed after construction is flat.

[0052] Reference Figure 4 In some embodiments of the present invention, the mounting seat 430 includes an arc portion, which is located above the smoothing roller 410. The cross section of the arc portion is semicircular and concentric with the cross section of the smoothing roller 410. There is a gap between the arc portion and the smoothing roller 410. The soil on the roadbed surface is uneven, and the smoothing roller 410 may bump when moving and may deviate relative to the smoothing roller shaft 420. After the smoothing roller 410 deviates, it contacts the arc portion, and the arc portion can resist the deviated smoothing roller 410 to prevent it from further deviating.

[0053] Reference Figure 1 and Figure 5In some embodiments of the present invention, the roadbed improvement device further includes a linear calibration mechanism 500, which includes a right-angle U-shaped plate 510, a correction link 520 and a second fixing member 540, the second fixing member 540 is connected to the side of the base 100, the correction link 520 is connected between the right-angle U-shaped plate 510 and the second fixing member 540, the correction link 520 is perpendicular to the second fixing member 540, the connection surface of the second fixing member 540 and the base 100 is perpendicular, and rollers 550 are respectively arranged on both sides of the bottom end of the right-angle U-shaped plate 510. The correction link 520 is perpendicular to the second fixing member 540, and the connection surface of the second fixing member 540 and the base 100 is perpendicular, thereby ensuring that the moving direction of the roadbed improvement device is parallel to the set moving direction.

[0054] The right-angle U-shaped plate 510 includes two wing plates and a web plate, the web plate is connected between the two wing plates, and the two wing plates are perpendicular to the web plate. The right-angle U-shaped plate 510 and the roller 550 are aligned with the set route on the ground, which can prevent the roadbed improvement device from deviating from the route during movement and affecting the construction quality. Rollers 550 are respectively provided on both sides of the bottom end of the right-angle U-shaped plate 510 to facilitate the movement of the right-angle U-shaped plate 510.

[0055] In some embodiments of the present invention, the distance between the correction link 520 and the base 100 is adjustable, so the distance between the correction link 520 and the base 100 can be adjusted according to the route, so as to adapt to the construction requirements of roadbeds of various widths. The distance between the correction link 520 and the base 100 can be adjusted in such a way that: the correction link 520 is slidably connected to the second fixing member 540, and the distance of the correction link 520 relative to the base 100 is changed by sliding the correction link 520 along the length direction of the second fixing member 540. The distance between the correction link 520 and the base 100 can be adjusted in such a way that: the correction link 520 is detachably connected to different positions in the length direction of the second fixing member 540 to change the distance between the correction link 520 and the base 100. Among them, the detachable connection method includes but is not limited to threaded connection, snap connection, etc.

The connecting member 530 is adjusted to change the connection position between the correction link 520 and the second fixing member 540 by connecting the connecting threaded holes 541 at different positions, thereby changing the distance between the correction link 520 and the base 100. It can be understood that the distance between the correction link 520 and the base 100 can match the width of the construction roadbed when the adjusting connecting member 530 is connected to the connecting threaded hole 541 at the set position. The adjusting connecting member 530 can be a threaded connecting member such as various screws and bolts.
