Description

[0001] The present invention relates to the field of roadbed reinforcement technology, in particular to a municipal road roadbed reinforcement device and process. Background Art

[0002] During the construction of highway subgrade, since the subgrade filling material in its natural state has a loose structure and poor strength and stability, the subgrade needs to be reinforced before the road is paved. There are many ways to reinforce the subgrade, among which quicklime pile foundation reinforcement method is one of them.

[0003] Lime piles refer to piles formed by manually or mechanically drilling holes in the foundation, filling them with quicklime, and then vibrating or tamping to form piles to reinforce the roadbed. Since the function of quicklime piles is to compact and reinforce the soil without bearing any load, admixtures and quicklime are usually mixed and then poured together when pouring quicklime. However, if the quicklime and admixture are mixed in advance, the moisture in the admixture will react with the quicklime, causing some of the quicklime to react before filling, affecting the compaction and reinforcement effect of the quicklime on the soil after filling.

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0042] like Figure 1 、 Figure 2 and Figure 3 As shown, a municipal roadbed reinforcement device and process include a spiral drill rod 3 for opening a material filling hole and filling the material, a material separation plate 7 for separating the filling material is fixedly connected to the inside of the spiral drill rod 3, a connecting block 1 for connecting to an external driving device, two feed hoppers 2 for replenishing the filling material are fixedly connected to the outer surface of the connecting block 1, the bottoms of the two feed hoppers 2 are both connected to the spiral drill rod 3, a discharge component 5 for spreading the material in the material filling hole is arranged at the bottom end of the spiral drill rod 3, a uniform component 4 for uniformly spreading the material in the filling hole is arranged on the discharge component 5, and a mixing component 6 for mixing the two filling materials is arranged between the spiral drill rod 3 and the discharge component 5.

[0043] like Figure 6 and Figure 7 As shown, the mixing assembly 6 includes a connecting shell 61 fixedly connected to the lower surface of the auger rod 3, a mounting bracket 64 is fixedly connected to the interior of the connecting shell 61, a conical dispersion cylinder 63 is fixedly connected to the top of the mounting bracket 64, and a polymerization bucket 62 is fixedly connected to the interior of the connecting shell 61 and above the conical dispersion cylinder 63.

[0044] like Figure 3 、 Figure 9 and Figure 11As shown, the discharging assembly 5 includes a fixed shell 51 slidably connected to the lower surface of the connecting shell 61 and two groups of left-right symmetrical pushing rods 52 fixed inside the mixing assembly 6. A first connecting spring is connected between the fixed shell 51 and the mixing assembly 6. The number of each group of pushing rods 52 is two and they are symmetrical front to back. Two discharge ports are set up in an upper and lower manner on the left and right sides of the outer surface of the fixed shell 51. Two symmetrical closing parts 53 for blocking the discharge ports are set at the interior of the fixed shell 51 corresponding to the position of the discharge ports. An auxiliary roller 54 is rotatably connected to the pushing rod 52.

[0045] like Figure 9 and Figure 11 As shown, the closing member 53 includes a second baffle 534 slidably connected to the inside of the fixed shell 51, the top of the second baffle 534 is fixedly connected to the fixing frame 532, the outer surface of the fixing frame 532 is slidably connected to the connecting slider 533, a second connecting spring is provided between the fixing frame 532 and the connecting slider 533, the top of the connecting slider 533 is fixedly connected to the first baffle 531, the first baffle 531 is slidably connected to the inner surface of the fixed shell 51, and the first baffle 531 and the second baffle 534 are both provided with a plurality of limit baffles for limiting the first baffle 531 in the left and right directions on the side away from the center of the fixed shell 51, and a connecting groove is provided on the side of the first baffle 531 away from the center of the fixed shell 51 and above the limit baffle, and the connecting groove is inclined from top to bottom away from the center of the discharge port, and the auxiliary roller 54 on the push rod 52 is slidably connected to the connecting groove.

[0046] By setting up the discharge component 5, quicklime and admixture can be evenly laid in the hole for filling, and quicklime and admixture can be mixed again in the process of filling into the hole, so as to avoid quicklime and admixture being mixed in advance, causing the quicklime and moisture in the admixture to react and cause the quicklime to expand in advance, and to avoid the situation that the quicklime is not compacted and consolidated enough around the hole after filling into the hole, so as to ensure the strength of the roadbed reinforcement.

[0047] During specific use, when drilling begins with the auger rod 3, the bottom end of the fixed shell 51 first contacts the ground. Under the action of the downward pressure of the external drive, the fixed shell 51 contracts toward the inside of the connecting shell 61. At this time, the first connecting spring is compressed, and the distance that the push rod 52 extends into the interior of the fixed shell 51 becomes longer. At this time, the auxiliary roller 54 on the bottom end of the push rod 52 slides inside the connecting groove on the first baffle 531. Since the connecting groove is inclined, when the fixed shell 51 slides toward the inside of the connecting shell 61, the push rod 52 pushes the first baffle 531 to slide toward the center of the fixed shell 51. At the same time, the first baffle 531 drives the second baffle 534 to slide synchronously through the connecting slider 533 to close the discharge port on the fixed shell 51. Due to the different widths of the two discharge ports set up above and below, when closing the discharge port, the two second baffles 534 located at the same discharge port are closed earlier than the two first baffles 531 located at the same discharge port. After the two second baffles 534 are closed, as the push rod 52 continues to push the first baffle 531 to move, the connecting slider 533 continues to slide on the fixing frame 532 and compresses the second connecting spring to ensure that the first baffle 531 and the second baffle 534 are closed. The second baffle 534 smoothly closes the discharge port. After the drilling is completed, the external drive continues to drive the auger rod 3 to rotate in place in the hole without applying downward pressure. After most of the remaining soil in the hole is discharged, the quicklime and admixture are loaded into the interior of the auger rod 3 through the feed hopper 2. When the quicklime and admixture fall into the interior of the mixing assembly 6, the quicklime and admixture are first aggregated together by the aggregation hopper 62, and then the aggregated quicklime and admixture are dispersed again by the conical dispersion cylinder 63. The quicklime and admixture are preliminarily mixed in turn, and then dropped into the mixing assembly 6. The inside of the fixed shell 51 is fixed, and then the auger rod 3 is lifted upward. At this time, the fixed shell 51 is no longer under pressure. Under the action of the first connecting spring and the push rod 52, the first baffle 531 and the second baffle 534 are restored to their original positions. At this time, the discharge port is in an open state, and the admixture is filled in the hole through the discharge port. The discharge holes arranged above and below can make the quicklime and admixture filled in the hole in a multi-strand manner during the rotation of the fixed shell 51 with the auger rod 3. The hole can be filled more evenly during the filling process, and there will be no excessive accumulation in certain positions due to excessive filling at one time.

[0048] like Figure 4 As shown, the uniform component 4 includes two connecting plates 41 hinged on the front and rear sides of the fixed shell 51, and the outer surface of the fixed shell 51 is provided with a placement groove at the corresponding position of the connecting plate 41. The lower surface of the connecting plate 41 is fixedly connected to the connecting main rod 44, and the connecting main rod 44 is provided with a plurality of retractable uniform members 43 for stirring the filler. The connecting plate 41 is provided with a limit member 42 for controlling the opening and closing of the uniform member 43, and a hydraulic push rod is provided between the connecting plate 41 and the fixed shell 51.

[0049] like Figure 4 、 Figure 5 and Figure 8 As shown, the limiting member 42 includes two connecting rods 421 arranged on the left and right sides and slidingly connected to the inside of the connecting plate 41, a third connecting spring is connected between the two connecting rods 421 and the connecting plate 41, the top ends of the two connecting rods 421 are commonly fixedly connected to the connecting cross plate 424, and the bottom ends of the two connecting rods 421 are commonly fixedly connected to the limiting sleeve 422, the internal rotation of the connecting plate 41 is connected to the auxiliary wheel 425 located above the connecting cross plate 424, the upper surface of the connecting cross plate 424 is fixedly connected to the connecting rope 423, and the end of the connecting rope 423 away from the connecting cross plate 424 passes through the auxiliary wheel 425 and is fixedly connected to the outer surface of the fixed shell 51, the limiting sleeve 422 is sleeved on the upper surface of the connecting main rod 44, and the inner diameter of the limiting sleeve 422 is larger than the inner diameter of the connecting main rod 44.

[0050] like Figure 4 As shown, the uniform member 43 includes a connecting seat 431 fixedly connected to the connecting main rod 44, and a stirring rod 433 is hinged at one end of the connecting seat 431 away from the connecting main rod 44. A spiral spring is connected between the connecting seat 431 and the stirring rod 433, and a limiting pull rope 432 is connected between the stirring rod 433 and the connecting main rod 44 for limiting the opening angle of the stirring rod 433.

[0051] By setting the uniform component 4, the quicklime and admixture filled in the hole can be further leveled and evened, so that the quicklime and admixture are further mixed in the hole and the quicklime can react with the moisture in the hole more quickly.

[0052] When filling is started, the hydraulic push rod pushes the connecting plate 41 to open the connecting plate 41 on the fixed shell 51. At this time, the connecting rope 423 on the connecting plate 41 is gradually pulled out from the inside of the connecting plate 41 during the opening process of the connecting plate 41. The connecting rope 423 drives the connecting rod 421 to slide toward the inside of the connecting plate 41 through the connecting cross plate 424, and the third connecting spring is compressed. At this time, the limiting sleeve 422 moves synchronously with the connecting rod 421. After the limiting sleeve 422 slides to the position of disengaging from the limit of the stirring rod 433, under the action of the scroll spring between the connecting seat 431 and the stirring rod 433, the retracted stirring rod 433 rotates on the connecting seat 431 and is in an open state. Through the setting of the limiting rope 432 , limiting the opening range of the stirring rod 433. At this time, the connecting plate 41 rotates with the fixed shell 51, and the quicklime and admixture filled in the hole are stirred and mixed through the stirring rod 433 and the connecting main rod 44. When drilling is required, the hydraulic push rod pulls the connecting plate 41 to retract on the fixed shell 51, and the connecting plate 41 is engaged in the corresponding placement groove on the fixed shell 51. At the same time, the connecting plate 41 is retracted on the fixed shell 51, and the connecting rope 423 no longer generates tension. Under the action of the elastic force of the third connecting spring itself, the connecting rod 421 and the limiting sleeve 422 are restored to their original positions. At this time, the limiting sleeve 422 retracts the stirring rod 433 together again during the process of returning to its original position, and is engaged in the inside of the placement groove to ensure smooth drilling.

[0053] like Figure 1 、 Figure 2 and Figure 3 As shown, a municipal road subgrade reinforcement device, and a method for using the above-mentioned municipal road subgrade reinforcement device to reinforce the subgrade include the following steps: S1, first connecting the auger rod 3 to the external drive through the connecting block 1, and driving the auger rod 3 to rotate by the external drive while applying downward force to drill holes on the subgrade. At this time, the discharge hole on the fixed shell 51 is in a closed state.

[0054] S2. After the drilling is completed, the external drive drives the auger rod 3 to continue rotating in the hole, but no downward pressure is applied to discharge the excess soil in the hole.

[0055] S3. After removing the remaining soil in the hole, stop the rotation of the auger rod 3, then add quicklime and admixture into the interior of the auger rod 3 through the feed hopper 2, and the quicklime and admixture are respectively located on both sides of the material partition plate 7 inside the auger rod 3.

[0056] S4. After the filling is completed, the auger rod 3 is restored to rotation and the auger rod 3 is slowly pulled upward in the hole. At this time, the quicklime and admixture leak out from the discharge port on the corresponding fixed shell 51 and fill the hole. At the same time, the quicklime and admixture filled in the hole are stirred evenly by the uniform component 4 and laid evenly in the hole.

[0057] Working principle: During specific use, first connect the auger rod 3 to the external drive through the connecting block 1, and drive the auger rod 3 to rotate through the external drive while applying downward force to drill a hole on the roadbed. At this time, the discharge hole on the fixed shell 51 is in a closed state. After the drilling is completed, the external drive drives the auger rod 3 to continue to rotate in the hole, but no longer applies downward pressure to discharge the excess soil in the hole. After the excess soil in the hole is discharged, the auger rod 3 stops rotating, and then the quicklime and admixture are loaded into the interior of the auger rod 3 through the feed hopper 2, and the quicklime and admixture are respectively located on both sides of the material partition plate 7 inside the auger rod 3. After filling, the auger rod 3 resumes rotation, and the auger rod 3 is slowly pulled upward in the hole. At this time, the quicklime and admixture leak out from the discharge port on the corresponding fixed shell 51 and fill the hole. At the same time, the quicklime and admixture filled in the hole are stirred evenly by the uniform component 4 and laid evenly in the hole.

S3, after removing the excess soil in the hole, stop the rotation of the auger rod, and then load quicklime and admixture into the interior of the auger rod through the feed hopper, and the quicklime and admixture are respectively located on both sides of the material partition plate inside the auger rod; S4. After filling, the auger rod is resumed to rotate, and the auger rod is slowly pulled upward in the hole. At this time, the quicklime and admixture leak out from the discharge port on the corresponding fixed shell and fill the hole. At the same time, the quicklime and admixture filled in the hole are stirred evenly by the uniform component and laid evenly in the hole.
