Description

Technical Field

[0001] This utility model relates to the field of treatment technology for the borehole walls of strongly weathered sandstone piles, specifically to an instant stabilizing shotcrete device for the borehole walls of strongly weathered sandstone piles. Background Technology

[0002] Strongly weathered sandstone pile holes refer to cylindrical holes formed in strongly weathered sandstone strata by mechanical or manual means, used for the construction of underground structures such as cast-in-place piles and anchor bolts.

[0003] The rock mass of the borehole wall is highly weathered, resulting in a loose structure and poor self-stabilization capacity. Special support measures are required to ensure borehole quality. For the poor stability and easy collapse of the borehole wall in strongly weathered sandstone piles, shotcrete reinforcement is a key technology to ensure borehole quality and subsequent construction safety. However, traditional shotcrete methods require segmented shutdowns for pipe replacement, leading to prolonged exposure of the borehole wall. Furthermore, using fixed nozzles can result in insufficient grout in fractured areas, and suspended nozzles are prone to swaying, creating blind spots in the shotcrete process. Therefore, an instant stabilization shotcrete device for strongly weathered sandstone pile borehole walls is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide an instant stabilizing shotcrete device for the borehole wall of strongly weathered sandstone piles, so as to solve the problems mentioned in the background art, which are that traditional shotcrete requires segmented shutdowns to replace pipes, resulting in long periods of exposed borehole wall, and that using a fixed nozzle can lead to insufficient grout in the fracture development zone, and that suspended nozzles are prone to swaying, causing blind spots in shotcreting.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: An instant stabilizing shotcrete device for the borehole wall of strongly weathered sandstone piles includes a base, a slurry tank fixed on the surface of the base, a pump box, a telescopic hose, and a roller. It also includes a mixing component and a driving component. The mixing component is installed inside the slurry tank, and the driving component is installed on the top of the base.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] Example like Figures 1 to 3 As shown, this embodiment provides an instant stabilizing shotcrete device for the borehole wall of strongly weathered sandstone piles, including a base 1, a slurry tank 2 fixed on the surface of the base 1, a pump box 5, a telescopic hose 6, and a roller 12. It also includes a mixing component and a driving component. The mixing component is installed inside the slurry tank 2, and the driving component is installed on the top of the base 1. When in use, the driving component controls the roller 12 to move up and down within the borehole wall of the strongly weathered sandstone pile for shotcrete treatment.

[0018] A slurry tank 2 is installed on the top of the base 1. The slurry inside the slurry tank 2 is mixed and stirred by the mixing component. The mixed slurry is transported to the roller 12 by the pump in the pump box 5. The roller 12 is then raised and lowered by the drive component to spray slurry at different locations inside the hole wall of the strongly weathered sandstone pile.

[0019] Reference Figure 1 and Figure 3 As one embodiment of this utility model, specifically, the drive assembly includes a hydraulic cylinder 7, a support frame 8 and a movable plate 9. The support frame 8 is fixedly connected to the top of the base 1, the hydraulic cylinder 7 is installed on the top of the support frame 8, the movable plate 9 is provided inside the support frame 8, and the movable plate 9 is connected to the output end of the hydraulic cylinder 7. The roller 12 is fixedly connected to the bottom of the movable plate 9.

[0020] The hydraulic cylinder 7 drives the movable plate 9 and roller 12 to move up and down, and spray grout at different positions inside the hole wall of the strongly weathered sandstone pile to ensure the stable movement of the roller 12, thereby ensuring the grout support effect on the hole wall of the strongly weathered sandstone pile.

[0021] Reference Figure 1 As one embodiment of this utility model, specifically, rectangular guide rails 11 are provided on both sides of the support frame 8, and guide rods 10 are fixedly connected inside the rectangular guide rails 11. The guide rods 10 are slidably connected to both ends of the movable plate 9.

[0022] Rectangular guide rails 11 are set on both sides of the support frame 8. The guide rods 10 inside the rectangular guide rails 11 are slidably connected to both ends of the movable plate 9 to support the vertical movement of the roller 12 and ensure the stability of the roller 12 during the movement process.

[0023] Reference Figure 1 and Figure 2 As one embodiment of this utility model, specifically, the mixing assembly includes a motor 4, a storage bin 14, a roller 15, and crossbars 16. The slurry tank 2 has a storage bin 14 inside, and the storage bin 14 has a roller 15 inside. The surface of the roller 15 has vertically arranged crossbars 16. The top of the slurry tank 2 is equipped with a motor 4, and the output end of the motor 4 is fixedly connected to the roller 15.

[0024] The slurry tank 2 is equipped with a storage chamber 14. The roller 15 inside the storage chamber 14 is driven by the motor 4 to rotate the crossbar 16, which stirs the slurry injected into the storage chamber 14, ensuring the mixing effect of the slurry and thus ensuring the support effect of the slurry on the borehole wall of the strongly weathered sandstone pile.

[0025] Reference Figure 1 and Figure 2 As one embodiment of this utility model, specifically, a feed inlet cover plate 3 is installed on the top of the slurry tank 2, a pump box 5 is fixedly connected to the side of the slurry tank 2, the pump input end inside the pump box 5 is connected to the bottom end of the slurry tank 2, and the pump output end inside the pump box 5 is connected to the roller 12 through a telescopic hose 6.

[0026] The pump in the pump box 5 delivers the mixed slurry to the roller 12 through the telescopic hose 6, ensuring that the mixed slurry is stably delivered to the roller 12 for use.

[0027] Reference Figure 1 and Figure 3 As one embodiment of this utility model, specifically, the roller 12 is provided with a cavity 17 inside, the cavity 17 is connected to the telescopic hose 6, and the bottom of the roller 12 is provided with equidistant discharge holes 18.

[0028] A cavity 17 is provided inside the roller 12 for storing slurry. As the slurry enters, the pressure inside the cavity 17 increases, and the slurry is sprayed out through the discharge hole 18, realizing the slurry spraying operation on the borehole wall of the strongly weathered sandstone pile.

[0029] Reference Figure 1 and Figure 3 As one embodiment of this utility model, specifically, a round hole 13 is provided on the top of the base 1 below the roller 12, and pulleys with locking function are installed around the bottom of the base 1.

[0030] The roller 12 is supported by the round hole 13 at the top of the base 1 and moved down into the hole of the strongly weathered sandstone pile. The base 1 is moved by the pulleys with locking function around the bottom of the base 1, which makes it easy to align the roller 12 with the hole of the strongly weathered sandstone pile and to lock and fix the position of the base 1.

[0031] Working principle: After drilling the strongly weathered sandstone pile hole, the base 1 is moved to a position above the strongly weathered sandstone pile hole. The position of the base 1 is adjusted so that the circular hole 13 on its surface is aligned with the strongly weathered sandstone pile hole. Then, the pulley is locked, and the slurry raw materials are added to the slurry tank 2 in sequence. The motor 4 is started to drive the roller shaft 15 and the crossbar 16 to rotate, mixing the slurry raw materials. Then, the hydraulic cylinder 7 is started to transport the roller 12 into the strongly weathered sandstone pile hole. After the slurry is mixed, the pump in the pump box 5 is started to transport the slurry through the telescopic hose 6 into the cavity 17 of the roller 12. As the pressure in the cavity 17 increases, the slurry is sprayed out through the discharge hole 18 to spray the wall of the strongly weathered sandstone pile hole. At the same time, the hydraulic cylinder 7 is started again to drive the roller 12 to move upward, increasing the pressure in the cavity 17. The slurry is sprayed out through the discharge hole 18 to spray different positions on the wall of the strongly weathered sandstone pile hole.
