Description

Technical Field

[0001] This utility model belongs to the field of soft roadbed treatment technology, and in particular relates to a soft roadbed treatment device for municipal highway engineering. Background Technology

[0002] The highway industry standard defines soft soil foundation as a weak soil layer with low strength and high compressibility. Most of it contains a certain amount of organic matter. The properties of soft soil are closely related to the stratification structure, depositional age, and genetic type of the foundation soil. Due to its engineering characteristics such as high water content, high compressibility, poor permeability, and strong rheological properties, soft soil generally cannot be used directly as a natural foundation and needs to be reinforced to reduce the settlement or uneven settlement of the highway subgrade under load.

[0003] Traditional reinforcement methods involve grooving to strengthen roadbeds. However, because the grooves are typically vertical, the grouting area is limited to the size of the groove. When the roadbed area is large, multiple grooving operations are required to ensure adequate grouting, thus reducing reinforcement efficiency and increasing the number of steps. For example, patent number CN202420906210.6 exhibits these problems, thereby affecting the efficiency of the reinforcement process. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides a soft subgrade treatment device for municipal highway engineering, which solves the problem that existing equipment cannot quickly treat large areas, thus affecting its treatment efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a soft subgrade treatment device for municipal highway engineering, comprising a support frame, a movable plate slidably mounted on the support frame, and a spiral filling pipe rotatably mounted on the movable plate, further comprising: an injection assembly mounted on the spiral filling pipe for transverse injection at the groove opening, including transverse injection pipes symmetrically slidably mounted on the spiral filling pipe, and multiple transverse injection pipes being connected through a flexible hose; and a drive unit mounted on the movable plate for driving the rotation of the spiral filling pipe and the sliding of the transverse injection pipes.

[0006] Preferably, the injection assembly further includes a spring sleeved on the transverse injection tube for resetting the transverse injection tube, a rotating cylinder rotatably disposed on the upper side of the spiral filling tube, and a material tube connected to the outside is disposed on the rotating cylinder, the material tube being connected to the flexible tube on the transverse injection tube, and multiple discharge holes being opened on the transverse injection tube.

[0007] Preferably, the drive unit includes a thrust assembly for extending the transverse injection tube and a drive assembly for driving the spiral filling tube and the thrust assembly. The thrust assembly includes a crankshaft rotatably disposed within the spiral filling tube, a wedge-shaped push plate mounted on the crankshaft, a pressure plate that movably contacts the push plate mounted at the end of the transverse injection tube, and a second gear mounted at the end of the crankshaft, which is driven by the drive assembly.

[0008] Preferably, the drive assembly includes a gear ring fixedly mounted on the spiral filling tube; a speed-changing gearbox mounted on the moving plate, wherein both the output end and the input end of the speed-changing gearbox are provided with a first gear, the first gear at the output end meshing with the gear ring; a drive motor mounted on the moving plate, wherein the output end of the drive motor is provided with a first half gear and a second half gear, the first half gear being movably meshed with the first gear at the input end of the speed-changing gearbox, and the second half gear being movably meshed with the second gear.

[0009] Preferably, the crankshaft is provided with an electromagnetic chuck that is magnetically attracted to the pressure plate, and the electromagnetic chuck is located on one side of the push plate.

[0010] The beneficial effects of this utility model are as follows: By using the spiral filling pipe in the equipment in conjunction with the drive unit and the movement of the moving plate, the roadbed can be effectively grouted. When the depth of the groove reaches a certain point, the drive unit drives the crankshaft to rotate, so that the push plate on the crankshaft can quickly push the transverse injection pipe out of the spiral filling pipe. This allows multiple transverse injection pipes to form a transverse distance outward, so that the equipment can not only inject grout into the center of the groove, but also into the outer side of the groove during the grouting process. This increases the grouting area, reduces the number of grooves, and makes the equipment more efficient, more practical, and more convenient to use. Attached Figure Description

[0017] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] according to Figures 1 to 4 As shown, a soft subgrade treatment device for municipal highway engineering includes a support frame 1, a movable plate 2 slidably mounted on the support frame 1, and a spiral filling pipe 3 rotatably mounted on the movable plate 2. It also includes: an injection assembly mounted on the spiral filling pipe 3 for transverse injection into the groove, comprising transverse injection pipes 5 symmetrically and slidably mounted on the spiral filling pipe 3, with multiple transverse injection pipes 5 connected through a flexible hose; and a drive unit mounted on the movable plate 2 for driving the rotation of the spiral filling pipe 3 and the sliding of the transverse injection pipes 5.

[0019] The injection assembly also includes a spring 6 sleeved on the transverse injection pipe 5 for resetting the transverse injection pipe 5. A rotating cylinder 4 is rotatably installed on the upper side of the spiral filling pipe 3, and a material pipe connected to the outside is provided on the rotating cylinder 4. The material pipe is connected to the flexible hose on the transverse injection pipe 5. Multiple discharge holes are opened on the transverse injection pipe 5 to facilitate the simultaneous supply of material to multiple transverse injection pipes 5, so that the curing liquid can be quickly injected into the foundation through the discharge holes on 5.

[0020] The drive unit includes a thrust assembly for extending the transverse injection tube 5 and a drive assembly for driving the spiral filling tube 3 and the thrust assembly. The thrust assembly includes a crankshaft 8 rotatably disposed inside the spiral filling tube 3. A wedge-shaped push plate 9 is mounted on the crankshaft 8. A pressure plate 7 that is in movable contact with the push plate 9 is mounted at the end of the transverse injection tube 5. A second gear 13 is mounted at the end of the crankshaft 8 and is driven by the drive assembly, which facilitates the simultaneous pushing of multiple transverse injection tubes 5 out of the spiral filling tube 3, thereby accelerating the injection efficiency of the equipment and further improving the working efficiency of the equipment.

[0021] The drive assembly includes a gear ring 10 fixedly mounted on the spiral filling tube 3; a gearbox 11 mounted on the moving plate 2, with a first gear 12 at both the output and input ends of the gearbox 11. The first gear 12 at the output end meshes with the gear ring 10. A drive motor 14 is mounted on the moving plate 2, with a first half gear 15 and a second half gear 16 mounted at the output end of the drive motor 14. The first half gear 15 meshes movably with the first gear 12 at the input end of the gearbox 11, and the second half gear 16 meshes movably with the second gear 13, facilitating the separate rotation of the spiral filling tube 3 and the crankshaft 8, making the equipment more convenient to use.

[0022] The crankshaft 8 is equipped with an electromagnetic suction block 17 that is magnetically attracted to the pressure plate 7, and the electromagnetic suction block 17 is located on one side of the push plate 9. This facilitates the retraction of the transverse injection tube 5 into the spiral filling tube 3, thereby avoiding the situation where the spring force of the spring 6 is too small, which would prevent it from retracting.

[0023] refer to Figure 1 The equipment is placed in a suitable position. Initially, the horizontal injection pipe 5 is positioned inside the spiral filling pipe 3. This prevents the spiral filling pipe 3 from being unable to slot due to the influence of the horizontal injection pipe 5. When the equipment begins slotting, the moving plate 2 is lowered, bringing the bottom of the spiral filling pipe 3 into contact with the ground. Simultaneously, the drive motor 14 is activated, which in turn drives the first half-gear 15 and the second half-gear 16 to rotate forward. Since the second gear 13 and the first gear 12 are respectively located on either side of the first half-gear 15 and the second half-gear 16, therefore... When the first half gear 15 drives the first gear 12 to rotate in the forward direction, the second half gear 16 is separated from the second gear 13. When the first half gear 15 drives the first gear 12 to rotate in the forward direction, the first gear 12 changes speed through the gearbox 11, and at the same time, the other first gear 12 drives the gear ring 10 to rotate. With the descent of the moving plate 2, the spiral filling pipe 3 can effectively groove the ground. When the depth of the groove grooving by the spiral filling pipe 3 reaches a certain position distance, the first half gear 15 disengages from the first gear 12, and at the same time, the second half gear 16 meshes with the second gear 13.

[0024] refer to Figure 3 and Figure 4When the spiral filling tube 3 is slotted to a certain depth, the spiral filling tube 3 stops rotating. At this time, the second half gear 16 drives the second gear 13 to rotate in the forward direction. When the second gear 13 rotates in the forward direction, the push plate 9 installed on the second gear 13 gradually moves closer to the pressure plate 7. Since the push plate 9 is wedge-shaped, the push plate 9 will gradually squeeze the pressure plate 7, causing the pressure plate 7 to push the transverse injection tube 5 to extend outward. At the same time, the spring 6 is squeezed. When the push plate 9 rotates to the appropriate position, the transverse injection tube 5 is fully extended. At this time, the material can be injected into the transverse injection tube 5 through the material tube on the rotating cylinder 4 and the hose connected between the transverse injection tube 5. The material is then discharged through the discharge hole on the transverse injection tube 5, thus realizing the injection of material into the position outside the slot.

[0025] This invention, through the spiral filling pipe 3 in the equipment, in conjunction with the drive unit and the movement of the moving plate 2, can effectively groove the roadbed. When the depth of the groove reaches a certain point, the drive unit drives the crankshaft 8 to rotate, so that the push plate 9 on the crankshaft 8 can quickly push the transverse injection pipe 5 out of the spiral filling pipe 3. This causes multiple transverse injection pipes 5 to form a transverse distance outward, so that the equipment can not only inject grout into the center of the groove, but also into the outer side of the groove during the grouting process. This increases the grouting area, reduces the number of grooves, and makes the equipment more efficient, more practical, and more convenient to use.

[0026] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
