This treatment method combines ice-water technology and gravel soil covering materials, aiming to improve the stability, bearing capacity and durability of the roadbed. The construction process of the ice-water accumulation block gravel soil cover is to first lay gravel soil on the roadbed surface, fill and compact it evenly to form a covering layer of a certain thickness; then use ice water to irrigate the covering layer, and strengthen the density of the gravel soil through the penetration and solidification of ice water; finally, trim and compact the covering layer to ensure that the surface is flat and firm; after the construction of the ice-water accumulation block gravel soil cover is completed, in order to Further increasing the soil of the overburden roadbed and increasing the bearing capacity of the overburden roadbed are usually reinforced by grouting drilling. Grouting drilling generally involves drilling first, cleaning the hole after drilling, and then performing concrete grouting. Drilling is the most important step. Currently, the drilling operation for the overburden of ice and water accumulation blocks and gravel soil cannot handle the side walls of the hole in a timely manner, resulting in the falling of soil blocks on the side walls of the hole due to the vibration of components such as the drill bit during drilling, which not only increases the difficulty of subsequent debris cleaning, but also easily affects the quality of drilling.

DETAILED DESCRIPTION

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] See also Figure 1A grouting and drilling device for a crushed stone soil covering layer of an ice-water accumulation block comprises a frame 1, a traveling mechanism 2, a stabilizing mechanism 3 and a drilling mechanism 4 installed above the frame 1; the frame 1 is composed of a base plate 11 and a support rod welding assembly 12 symmetrically installed on the base plate 11 front and back, and a drilling mechanism 4 is commonly arranged between the two support rod welding assemblies 12; a traveling mechanism 2 composed of universal wheels is arranged at the four corners of the bottom of the base plate 11, and four groups of stabilizing mechanisms 3 are arranged at the middle positions of the edges around the base plate 11.

[0024] See also Figure 1 and Figure 2 The drilling mechanism 4 includes a drilling fixed plate 41 installed between two support rod welding assemblies 12, hydraulic rods are fixedly installed on the left and right sides above the bottom plate 11, the upper ends of the fixed ends of the hydraulic rods penetrate and are fixedly installed on the drilling fixed plate 41, and a drilling movable seat 43 is commonly connected above the telescopic ends of the hydraulic rods, a drill rod 42 is vertically slidably arranged in the middle position of the drilling fixed plate 41, and the drill rod 42 can rotate relative to the drilling fixed plate 41, and a driving motor 44 is fixedly installed above the drilling movable seat 43, and the output shaft of the driving motor 44 is connected to the drill rod 42, and the drill rod 42 is rotatably connected to the drilling movable seat 43, and a drill bit is threadedly connected to the lower end of the drill rod 42; guide rods 45 are evenly arranged at the bottom of the drilling movable seat 43 and located around the drill rod 42, and the guide rods 45 slide through the drilling fixed plate 41, and a tamping assembly 46 is arranged at the lower end of the drill rod 42 and located above the drill bit.

[0025] During specific work, the drive motor 44 is started to drive the drill bit to rotate at high speed through the drill rod 42, and the hydraulic rod is started at the same time to drive the drive motor 44, the drill rod 42 and the drill bit to move downward through the drilling moving seat 43, and the drilling effect is achieved by the drill bit rotating while descending; while drilling, the compacting component 46 works synchronously to continuously and evenly beat the hole wall in the circumferential direction, so as to ensure the compactness of the hole wall and avoid the falling of soil blocks due to the vibration of the drill bit during drilling, which affects the drilling quality and increases the difficulty of cleaning the debris.

[0026] See Figure Figure 4-Figure 6 The tamping assembly 46 includes a cam ring 461 fixedly mounted on the drill rod 42, and the outer wall of the cam ring 461 is a wavy structure; the bottom of the guide rod 45 is commonly connected to a T-shaped sleeve 462 mounted on the outside of the drill rod 42, and a plurality of slide grooves are provided on the side wall of the T-shaped sleeve 462 corresponding to the raised portion of the cam ring 461, and the slide grooves are radially slidably connected with a tamping plate 464 through a transverse plate 463 arranged through the T-shaped sleeve 462, and a return spring 465 is connected between the side wall of the transverse plate 463 and one side wall of the slide groove, and the end of the part of the transverse plate 463 located in the T-shaped sleeve 462 is an arc structure that cooperates with the cam ring 461.

[0027] During operation, the drill rod 42 rotates and drives the cam ring 461 to rotate. When the raised part of the cam ring 461 contacts the arc structure of the cross plate 463, the cross plate 463 is pushed and moves radially outward. At this time, the reset spring 465 is compressed, and the cross plate 463 moves outward, driving the tamping plate 464 to move synchronously with the side wall of the borehole. When the recessed part of the cam ring 461 contacts the arc structure of the cross plate 463, the cross plate 463 drives the tamping plate 464 to reset under the action of the reset spring 465. During the drilling process, the drill rod 42 drives the cam ring 461 to rotate, so that the tamping plate 464 slides radially back and forth, thereby achieving the purpose of reciprocatingly beating the side wall of the borehole in the circumferential direction to enhance the compactness of the side wall of the borehole.

[0028] See also Figure 4 , Figure 6 The drilling mechanism 4 also includes a flattening component 47. Specifically, a slide groove 2 is opened on the two side walls of the slide groove 1, a slider 1 is slidably arranged in the slide groove 2, an axle rod 471 is arranged between the opposite sides of the two sliders, and the cross plate 464 is rotatably installed on the axle rod 471.

[0029] In order to prevent the horizontal plate 463 from rotating randomly, thereby causing the tamping plate 464 to be unable to effectively beat the side wall of the borehole, the present invention further provides multiple groups of tensioning units corresponding to the horizontal plates 463 one by one between each horizontal plate 463 and the T-shaped sleeve 462, such as Figure 4-Figure 5 As shown, the tensioning unit includes a pair of ear plates 472 installed on the side wall of the T-shaped sleeve 462, and a rotating shaft 1 is rotatably connected between the ear plates 472. A pull rope 473 is wound on the rotating shaft 1 through a spiral spring (not shown in the figure), and the other end of the pull rope 473 is fixedly connected to the cross plate 463. The pull rope 473 applies tension to the cross plate 463 to prevent the cross plate 463 from rotating due to the gravity of the tamping plate 464. The volute spring is set so that the pull rope 473 is always wound around the rotating shaft 1, and the cross plate 463 maintains a horizontal state in the absence of external force. When the cam ring 461 pushes the cross plate 463 to slide radially outward, the elastic force of the spiral spring can be overcome to stretch the pull rope 473, thereby avoiding affecting the slapping effect of the tamping plate 464 on the side wall of the borehole.

[0030] Continue reading Figure 4-Figure 5The flattening assembly 47 also includes a driving unit. Specifically, the driving unit includes a plurality of small discs 474 coaxially arranged on each rotating shaft 1, and arc grooves 3 that are at a certain angle to the axis of the small discs 474 are evenly provided on the circumferential side walls; a rotating groove is provided on the bottom wall of the horizontal section of the T-shaped sleeve 462, and a large disc 475 that is sleeved on the outside of the T-shaped sleeve 462 is rotatably installed in the rotating groove through a plurality of support rods, and a toggle rod 476 is evenly provided on the bottom wall of the large disc 475 with its axis as the center, and the toggle rod 476 cooperates with the arc grooves 3 opened on the plurality of small discs 474 at the same time; teeth are evenly provided on the circumferential side walls of the large disc 475, and a gear 477 that cooperates with the teeth on the large disc 475 is rotatably installed on the T-shaped sleeve 462 through the rotating shaft 2, and the gear 477 is driven by an external motor.

[0031] During operation, when the drilling is completed, the driving motor 44 stops running when the cam ring 461 rotates to the position where the protruding part contacts the arc structure of the horizontal plate 463 through the drill rod 42. At this time, the tamping plate 464 contacts the side wall of the drill hole and the return spring 465 is in a compressed state. The tamping plate 464 presses the side wall of the drill hole under the action of the return spring 465, and then the drill rod 42 is driven by the hydraulic rod to move upward and withdraw from the drill hole. At the same time, the external motor is started to rotate the gear 477, and the rotation of the gear 477 drives the large disc 475 to rotate. Through the cooperation of the toggle rod 476 and the arc groove three, the large disc 475 drives multiple small discs 474 to rotate synchronously, and the small discs 474 The rotation drives the corresponding rotating shaft 1 to rotate, and then each pull rope 473 is wound around the corresponding rotating shaft 1. The pull rope 473 pulls the cross plate 463 to rotate around the shaft 471, so that an inclination angle is formed between the tamping plate 464 and the side wall of the borehole, with the lower end in contact and the upper end away from the side wall of the borehole. During the upward movement of the drill rod 42, the lower end of the tamping plate 464 is tightly against the side wall of the borehole to achieve the effect of pressing and leveling while rising. The present invention cooperates with the driving unit and the tensioning unit to make the tamping plate 464 rotate and tilt at a certain angle, so that the tamping plate 464 exerts a stronger pressing force on the side wall of the borehole, thereby further ensuring the compactness of the side wall of the borehole and improving the drilling quality.

[0032] See also Figure 3 The lower two ends of the tamping plate 464 are structures inclined toward the drill rod 42. On the one hand, this avoids scraping when the drill rod 42 drives the tamping plate 464 to move downward and the tamping plate 464 just contacts the side wall of the borehole during the drilling process, resulting in poor borehole formation quality and more soil scraped off; on the other hand, this avoids affecting the borehole formation quality due to the small contact area between the tamping plate 464 and the side wall of the borehole when the drill rod 42 drives the inclined tamping plate 464 to move upward.

[0033] See also Figure 4The cross plate 463 is provided with support plates 4631 on the upper and lower sides of one end close to the tamping plate 464, and the other ends of the two support plates 4631 are respectively connected to the upper and lower parts of the inner side surface of the tamping plate 464, and the cross plate 463 and the two support plates 4631 together form a triangular support for the tamping plate 464. When the cross plate 463 slides radially outward under the action of the cam ring 461 and the tamping plate 464 contacts the side wall of the borehole, the uniformity of the beating of the side wall of the borehole by the tamping plate 463 as a whole can be ensured.

[0034] See also Figure 1 , Figure 3 The stabilizing mechanism 3 includes an L-shaped rod 31 vertically slidably mounted on the bottom plate 11, and the L-shaped rod 31 can rotate. The vertical section of the L-shaped rod 31 penetrates downwardly through the bottom plate 11 and is rotatably connected to a stabilizing seat 32. A stabilizing spring 33 is sleeved on the portion of the L-shaped rod 31 between the stabilizing seat 32 and the bottom plate 11. The stabilizing spring 33 is fixedly connected to the stabilizing seat 32 and the bottom plate 11. A semi-arc plate 34 with an opening near the outer side of the bottom plate 11 is fixedly mounted on the bottom plate 11. The semi-arc plate 34 is located outside the vertical section of the L-shaped rod 31. One side of the upper end of the semi-arc plate 34 is provided with a stabilizing spring 33 that is connected to the L-shaped rod 31. The horizontal section is partially matched with the arc-shaped groove 1; when the device is performing drilling operations, the height of the stabilizing seat 32 is lower than the walking mechanism 2, so that it can contact the road surface to achieve the purpose of stabilizing the device. At this time, the horizontal section of the L-shaped rod 31 is located at the opening of the semi-arc plate 34; when the device is in a moving state, the height of the stabilizing seat 32 is higher than the walking mechanism 2, so that it does not contact the road surface. At this time, the horizontal section of the L-shaped rod 31 is located in the arc-shaped groove 1; an arc-shaped groove 2 is opened on the outside of the semi-arc plate 34 on the bottom plate 11, and a cylinder 35 is slidably installed in the arc-shaped groove 2 through a slider, and the telescopic end of the cylinder 35 is connected to the horizontal section of the L-shaped rod 31.

[0035] When the device is in use, the cylinder 35 drives the L-shaped rod 31 to move upward along the opening of the semi-arc plate 34. At this time, the stabilizing spring 33 is compressed. When it moves upward to a position higher than the top of the semi-arc plate 34, the L-shaped rod 31 is manually controlled to rotate so that its horizontal section is located directly above the arc groove 1. The cylinder 35 is controlled so that the horizontal section of the L-shaped rod 31 is located in the arc groove 1. The arc groove 1 is used to limit the L-shaped rod 31 in the vertical direction to ensure that the stabilizing seat 32 does not contact the road surface. When the device needs to drill a hole, the cylinder 35 is controlled to drive the L-shaped rod 31 to move upward so that it is aligned with the arc groove. Once disengaged, rotate the L-shaped rod 31 so that its horizontal section is located above the opening of the semi-arc plate 34, and control the cylinder 35 again to drive the L-shaped rod 31 to move downward. When the stabilizing seat 32 drops to contact the road surface, the stabilizing spring 33 is still in a compressed state. Therefore, under the action of the stabilizing spring 33, the entire device moves upward, and the walking mechanism 2 does not contact the road surface, thereby achieving the purpose of stabilizing the device during the drilling operation. It should be noted that the stabilizing spring 33 is not a common spring in life, but an industrial spring, and the elastic force it provides is sufficient to support the entire device.
