Description

Technical Field

[0001] This utility model relates to the field of pile foundation construction equipment technology, specifically to a rapid drilling and grouting equipment for pile foundation engineering. Background Technology

[0002] Drilled cast-in-place piles are piles made by forming pile holes in the foundation soil through mechanical drilling, steel pipe extrusion, or manual excavation on the engineering site, placing a steel cage inside, and pouring concrete. Depending on the hole-forming method, cast-in-place piles can be divided into several categories such as driven cast-in-place piles, drilled cast-in-place piles, and excavated cast-in-place piles.

[0003] Currently, there are various types of pile foundation drilling equipment on the market. However, when these drilling devices are drilling, the drill rod will bring soil onto the movable base plate. When the drill rod leaves the hole, the soil on the movable base plate is likely to fall into the hole, which can lead to soil backfilling in the drilled hole and affect drilling efficiency.

[0004] The prior art proposes a Chinese patent with publication number CN215715270U to solve the above-mentioned technical problems. The technical solution disclosed in this patent document is as follows: a rapid drilling and grouting equipment for pile foundation engineering, including a movable base, a number of moving wheels installed at the bottom end of the movable base, and a drilling vertical support connected to the top end of the movable base. The surface of the movable base has a through hole, a drilling machine is slidably connected to the inner side of the drilling vertical support, a drill rod is provided at the bottom end of the drilling machine, and movable soil-removing plates are slidably connected to both sides of the inner side of the drilling vertical support. This application, by setting up a movable block, a moving frame, an incomplete gear, a rotating rod, a transmission rack, and a movable soil-removing plate, enables the movable soil-removing plate to remove soil that falls onto the movable base during drilling, thus preventing soil from falling into the drilled hole and improving the working efficiency of the drilling equipment. However, the soil-removing plate 15 moves horizontally back and forth on the surface of the movable base 8. Although it can remove the soil on the movable base 8, it can only move back and forth relative to the drilling vertical support 4. The soil that falls onto the moving frame 11 will also scatter in all directions under the action of vibration. At this time, the scattered soil particles may fall into the drilled hole, affecting the drilling quality and increasing the workload of subsequent hole cleaning and other processes. Utility Model Content

[0005] The purpose of this invention is to provide a rapid drilling and grouting device for pile foundation engineering to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A rapid drilling and grouting device for pile foundation engineering includes an equipment support frame, a drill rod, and a drill rod drive motor. A soil barrier component is disposed below the drill rod. The soil barrier component includes a soil barrier cover. A support cylinder is fixedly connected to the top of the inner wall of the soil barrier cover. A support base is fixedly connected to the bottom end of the support cylinder. A side mounting plate is fixedly connected to the outer wall of the soil barrier cover near the bottom end. A drive component for driving the soil barrier cover to rise and fall is disposed at the top of the side mounting plate.

[0008] A further improvement of this utility model is that: the driving component includes a barrier cover hydraulic rod, the extended end of the barrier cover hydraulic rod is fixedly connected to a docking block, the docking block is detachably fixedly connected to the top of the side mounting plate by bolts, the top of the side mounting plate is provided with a docking hole adapted to the bolts, and the top of the barrier cover hydraulic rod is fixedly connected to the inner wall of the equipment support frame by the mounting block.

[0009] A further improvement of this utility model is that the inner wall of the mating hole is threadedly connected to the outer wall of the bottom end of the bolt, and a gasket is fixedly connected to the bottom surface of the mating block.

[0010] A further improvement of this utility model is that a movable base is fixedly connected to the bottom surface of the equipment support frame, and the side of the side mounting plate is slidably connected to the inner wall of the movable base.

[0011] A further improvement of this utility model is that the bottom surface of the movable base is fixedly connected with casters.

[0012] A further improvement of this utility model is that: the output end of the drill rod drive motor is fixedly connected to the top of the drill rod; the outer wall of the drill rod is movably connected to the inner wall of the support cylinder; a motor mounting bracket is fixedly connected to the outer wall of the drill rod drive motor; and a drilling hydraulic rod is fixedly connected to the top of the motor mounting bracket.

[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0014] This invention provides a rapid drilling and grouting device for pile foundation engineering. By activating the hydraulic rod of the soil barrier cover, the soil barrier cover is pushed to fit against the ground, aligning the support cylinder with the pre-drilled position. During drilling, soil that falls off the drill rod due to vibration and gravity is blocked by the soil barrier cover, preventing it from falling into the drilled hole. It provides comprehensive, all-around protection, greatly improving the protection effect on the borehole, ensuring drilling quality, and reducing the workload of subsequent hole cleaning and other processes.

[0015] This invention provides a rapid drilling and grouting device for pile foundation engineering. After drilling is completed, the hydraulic rod of the soil barrier pulls the soil barrier upward, and the soil slides down under gravity to the outside of the soil barrier's coverage area, facilitating cleanup. Alternatively, the soil can be cleaned first and then the soil barrier can be lifted, offering flexible operation. The entire device has a reasonable structural design, with all components working together to improve construction efficiency and convenience. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to embodiments: Example

[0023] like Figure 1-4As shown, this utility model provides a rapid drilling and grouting device for pile foundation engineering, including a device support frame 1, a drill rod 2 and a drill rod drive motor 3. A soil barrier component 8 is provided below the drill rod 2. The soil barrier component 8 includes a soil barrier cover 9. A support cylinder 16 is fixedly connected to the top of the inner wall of the soil barrier cover 9. A support base frame 17 is fixedly connected to the bottom end of the support cylinder 16. A side mounting plate 11 is fixedly connected to the outer wall of the soil barrier cover 9 near the bottom end. A drive component for driving the soil barrier cover 9 to rise and fall is provided at the top of the side mounting plate 11.

[0024] The drive assembly includes a barrier cover hydraulic rod 10. A docking block 12 is fixedly connected to the extended end of the barrier cover hydraulic rod 10. The docking block 12 is detachably fixedly connected to the top of the side mounting plate 11 by bolts 14. The top of the side mounting plate 11 has a docking hole 15 that matches the bolts 14. The top of the barrier cover hydraulic rod 10 is fixedly connected to the inner wall of the equipment support frame 1 by the mounting block. Example

[0025] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the inner wall of the mating hole 15 is threadedly connected to the outer wall of the bottom end of the bolt 14, and a gasket 13 is fixedly connected to the bottom surface of the mating block 12.

[0026] The bottom surface of the equipment support frame 1 is fixedly connected to the movable base 6, and the side of the side mounting plate 11 is slidably connected to the inner wall of the movable base 6.

[0027] The bottom surface of the movable base 6 is fixedly connected with casters 7, the output end of the drill rod drive motor 3 is fixedly connected to the top of the drill rod 2, the outer wall of the drill rod 2 is movably connected to the inner wall of the support cylinder 16, the outer wall of the drill rod drive motor 3 is fixedly connected with a motor mounting bracket 4, and the top of the motor mounting bracket 4 is fixedly connected with a drilling hydraulic rod 5.

[0028] The working principle of the rapid drilling and grouting equipment used in this pile foundation project will be explained in detail below.

[0029] like Figure 1-4 As shown, during use, before drilling, the hydraulic rod 10 of the barrier cover is activated, which pushes the side mounting plate 11, causing the side mounting plate 11 to bring the soil barrier cover 9 into contact with the ground, while the support cylinder 16 is aligned with the reserved position of the drilling hole.

[0030] Next, the drill rod drive motor 3 is started, which drives the drill rod 2 to drill a hole in the soil. During the drilling process, the soil is transported upwards along the spiral grooves on the drill rod 2 and falls off the drill rod 2 under the action of vibration and gravity. The fallen soil falls onto the outer wall of the soil barrier 9 and is blocked by the soil barrier 9, thus preventing soil from falling into the drilled hole. Moreover, the soil barrier 9 can completely and without blind spots prevent soil from falling into the drill hole, further improving the protection effect of the drill hole.

[0031] After drilling is completed, the hydraulic rod 10 of the soil barrier 9 is activated, pulling the soil barrier 9 upward. Under the influence of gravity, the soil on the soil barrier 9 gradually slides outward from the area covered by the soil barrier 9. Alternatively, the soil can be cleared first before lifting the soil barrier 9.

[0032] It should be noted that, in this document, the terms "comprising," "including," or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. The present invention has been described in detail above, but modifications or improvements can be made based on it, which will be apparent to those skilled in the art. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
