Description

Technical Field

[0001] This utility model relates to the field of geotechnical engineering foundation construction technology, and in particular to a bare rock borehole backfilling device. Background Technology

[0002] In the construction of infrastructure projects such as ports, wind power plants, and bridges, it is often necessary to drill pilot holes in bare rock foundations and construct artificial foundations or anchoring structures by backfilling with specific materials. Currently, on-site construction often employs specialized equipment: the equipment's built-in conveyor system delivers the material into the holes, and then a heavy hammer is used to compact the material in layers.

[0003] However, the feeding process in existing technologies has significant drawbacks. Typically, materials enter the pilot hole through a discharge port or a simple guide chute, either by free fall or a short drop. This method has the following prominent problems: First, material impact can easily cause borehole collapse. Although the working face is bare rock, the actual borehole opening is often surrounded by loose residual soil, completely weathered rock layers, and drilling debris, making the structure extremely unstable. The impact force generated by the falling material, as well as the vibration transmitted by the subsequent hammer operation, can easily cause this vulnerable area to collapse. Furthermore, the simple feeding method makes it difficult to achieve precise quantitative control, which will interrupt the continuous operation process and reduce construction efficiency.

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A bare rock borehole backfilling device includes a device body and further includes: A guide component located below the main body of the device and at the discharge point; The guiding component includes a cover located below the main body of the device, and a settling shell is provided below the discharge end of the cover.

[0006] As a preferred embodiment of the bare rock guide hole backfilling device of this utility model, the guiding component further includes a guide rail disposed below the device body. Two guide rails are provided and symmetrically distributed on both sides below the device body. A sliding seat is horizontally slidably connected inside the guide rail, and the lower part of the sliding seat is fixedly connected to the cover.

[0007] As a preferred embodiment of the bare rock borehole backfilling device of this utility model, the cover is designed to be narrow at the front and wide at the back, and the cover is a semi-circular shell.

[0014] As a preferred embodiment of the bare rock guide hole backfilling device of this utility model, when the cover body extends outward, the settling shell, the discharge hole and the ramming hammer of the device body are on the same axis.

[0015] The beneficial effects of this utility model are as follows: When the device body needs to backfill the pilot hole, the material can be smoothly guided into the pilot hole through the extendable cover, reducing material loss; the settling shell extending into the pilot hole can effectively prevent the material from impacting the area around the pilot hole opening when it is discharged, thus preventing the pilot hole opening from collapsing. At the same time, when the material enters the pilot hole through the settling shell, the material causes the settling shell to descend due to friction with the inner wall of the settling shell. The conical cover on the surface of the settling shell can compact the pilot hole opening, thereby achieving the effect of compacting the opening and effectively ensuring the regularity of the pilot hole.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example 1: Reference Figures 1-5This is the first embodiment of the present utility model. This embodiment provides a bare rock guide hole backfill device, including a device body 100; and a guide component 200 disposed below the device body 100 and located at the discharge point; wherein, the guide component 200 includes a cover 210 disposed below the device body 100, and a settling shell 220 is disposed below the discharge end of the cover 210.

[0026] The aforementioned device body 100 is a tracked compaction machine, and its main components are... Figure 1 The system consists of a tracked mobile platform at point A, a material carriage at point B, a tamping device at point C, and a conveyor belt mechanism located on the tracked mobile platform and below the material carriage. During the backfilling operation of the pilot hole, the equipment first travels to the pilot hole, aligning the discharge port roughly with the hole opening. Then, the conveyor belt is started to feed a fixed amount of material into the hole (usually not filled all at once, but in layers, such as filling 1 / 4 of the hole depth). The equipment then fine-tunes its position so that the tamping hammer is aligned with the hole opening. A winch lowers the tamping hammer to the material surface, then lifts it and allows it to fall freely, using impact energy to repeatedly compact the fill material until the layer reaches the required density. This feeding and compaction process is repeated until the pilot hole is backfilled to the design elevation with high quality, thus completing the backfilling operation.

[0027] Example 2: Reference Figures 2-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0028] Specifically, the guide component 200 also includes a guide rail 211 disposed below the device body 100. There are two guide rails 211 and they are symmetrically distributed on both sides below the device body 100. A slide block 212 is horizontally slidably connected inside the guide rail 211. The lower part of the slide block 212 is fixedly connected to the cover 210.

[0029] When the device body 100 moves to the vicinity of the pilot hole and needs backfilling, the personnel first pull out the cover 210 under the device body 100. At this time, the guide rail 211 and the slide 212 can axially limit the cover 210 until the discharge hole of the cover 210 is aligned with the pilot hole. At this time, the device body 100 can unload the material. The material will be transported into the cover 210 by the conveyor belt. At this time, the material will slide down the inner wall of the cover 210 from the discharge hole to the slide 212, thus achieving the effect of smooth backfilling. This can effectively avoid the problem that traditional feeding can easily cause the material to fail to enter the hole accurately and spill around the pilot hole, resulting in material loss.

[0030] Specifically, the cover 210 has a design that is narrow in the front and wide in the back, and the cover 210 is a semi-circular shell.

[0031] With the above design, when the material pile slides down the inner wall of the cover 210, it can be gathered by the gradually narrowing space of the cover 210, which is narrow at the front and wide at the back, to prevent the material from being too loose and affecting the feeding efficiency or the existence of material residue.

[0032] Specifically, the front section of the cover 210 is a closed design.

[0033] The above design can block the path of the material, allowing it to enter the discharge hole completely.

[0034] Specifically, all the inner corners of the cover 210 are rounded.

[0035] The above design avoids the problem of material residue or incomplete discharge caused by the presence of corners, thus improving the material discharge efficiency.

[0036] Specifically, a discharge hole is provided on the lower inner side of the cover 210, and the diameter of the discharge hole is the same as the diameter of the hammer of the device body 100.

[0037] Example 3: Reference Figures 4-5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0038] Specifically, the settling shell 220 is located inside the discharge port of the cover 210, and the settling shell 220 is designed to slide vertically.

[0039] When the material falls into the inlet hole through the settling hole, the friction between the material and the inner wall of the settling shell 220 can be combined with the overall weight of the material to drive the settling shell 220 to move downward. Specifically, a spring 222 is fixedly connected to the surface of the settling shell 220, and the upper end of the spring 222 is fixedly connected to the cover 210.

[0040] When the settling shell 220 is pressed down, the spring 222 will stretch accordingly, which can drive the settling shell 220 to return to its original position after the material is discharged in one go. Specifically, a conical cover 221 is provided below the surface of the settling shell 220, which is used to compact the opening of the pilot hole.

[0041] The "bare rock" geological environment used in this device does not refer to an idealized, intact, smooth bedrock surface during construction. The bare rock surface is often covered with residual soil of varying thicknesses, as well as completely weathered or strongly weathered layers. Furthermore, after drilling, a large amount of loose rock cuttings and debris generated during drilling remains around the borehole opening, forming an extremely fragile and easily collapsible fractured zone. Traditional direct feeding methods, due to the impact of the material and the vibration of the tamping hammer, can easily cause this loose area to collapse, thus contaminating the backfill material, reducing the effective borehole diameter, and seriously affecting construction quality and safety. Therefore, in order to address the above-mentioned problem, when the settling shell 220 moves downward due to the weight of the material, the conical shell on its surface and located at the opening of the inlet hole can use its conical surface to squeeze the opening of the inlet hole, so that the soil at the opening of the inlet hole can be more compacted and collapse can be avoided. Specifically, when the cover 210 extends outward, the settling shell 220, the discharge hole, and the ram of the device body 100 are on the same axis.

[0042] The above design ensures the smooth movement of the hammer and the accuracy of the impact.

[0043] During operation, when backfilling the pilot hole, the equipment is first driven to the pilot hole, with the discharge port roughly aligned with the hole opening. Then, the cover 210 is pulled out from under the main body 100, aligning its discharge port with the pilot hole. The material discharged from the main body 100 is then smoothly guided into the pilot hole by the cover 210, reducing material loss. The settling shell 220, extending into the pilot hole, effectively prevents material from impacting the area around the pilot hole opening during discharge, thus avoiding collapse of the pilot hole opening. Simultaneously, as the material passes through the settling shell 220 into the pilot hole, the material flow is controlled. The material is rubbed against the inner wall of the settling shell 220, causing the settling shell 220 to descend. The conical cover 221 on the surface of the settling shell 220 can compact the opening of the pilot hole to achieve the effect of compacting the opening. This can effectively ensure the regularity of the pilot hole. After the material is backfilled once, the hammer is aligned with the opening, and the winch lowers the hammer to the material surface. The winch lifts the hammer and lets it fall freely, using impact energy to repeatedly compact the fill material until the layer reaches the density requirement. The above feeding and compaction steps are repeated until the pilot hole is backfilled to the design elevation with high quality, and the backfilling operation is completed.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
