Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and more specifically, to an adjustable building foundation reinforcement device. Background Technology

[0002] In modern construction engineering, the stability of the foundation is directly related to the safety and service life of the entire building. Currently, the mainstream foundation reinforcement method mainly relies on the traditional steel cage structure. This structure is formed by inserting the steel cage into the ground and then pouring concrete. However, this simple columnar structure has a limited contact area with the surrounding soil layer, resulting in an unsatisfactory reinforcement effect. Especially under complex geological conditions, it cannot fully play the role of foundation reinforcement.

[0003] In actual construction, traditional column-based reinforcement structures often suffer from insufficient bonding force with the soil layer, making them prone to uneven settlement or local collapse during long-term use. This not only affects the overall stability of the building but may also pose serious safety hazards. At the same time, because traditional reinforcement methods lack an effective interlocking mechanism with the stratum, the foundation's seismic resistance and scour resistance are relatively weak when encountering natural disasters such as earthquakes and rainstorms, failing to meet the high requirements of modern building engineering for foundation stability.

[0030] The inner wall of the snap-fit ​​sleeve 8 is provided with a guide plate 17, and multiple sets of guide plates 17 are provided. The outer wall of the insertion tube 2 is provided with a guide groove 18, and multiple sets of guide grooves 18 are provided and are slidably connected to multiple sets of guide plates 17 respectively.

[0031] The outer side of the snap-fit ​​sleeve 8 is provided with a slide rod 19. Multiple sets of slide rods 19 are provided and are all slidably connected to the slide sleeve 11. A compression spring 20 is provided between the slide sleeve 11 and the snap-fit ​​sleeve 8. Multiple sets of compression springs 20 are provided.

[0034] The outer walls of multiple push blocks 6 and push rods 5 are all equipped with rounded corners. The rounded corner design reduces the motion resistance between push blocks 6 and push rods 5, making their sliding smoother.

[0035] A positioning mechanism is provided on the outside of the snap-fit ​​sleeve 8. The positioning mechanism includes a mounting ring 23, a positioning block 24, a compression spring 25, a positioning ring 26, and a positioning groove 27. The mounting ring 23 is fixed on the top surface of the conical shell 1. Multiple sets of positioning blocks 24 are slidably installed inside the mounting ring 23.

[0036] The tops of the multiple positioning blocks 24 and the positioning grooves 27 are all set in an arc shape. The arc shape design of the positioning blocks 24 and the positioning grooves 27 allows them to transition smoothly when they come into contact with each other, reducing wear.

[0037] In this embodiment, the conical shell 1 is first placed inside the foundation, and the insertion tube 2 is connected to the external cement mortar delivery pipe. Then, the insertion tube 2 is inserted into the snap-fit ​​sleeve 8 and the conical shell 1. The insertion tube 2 is positioned and inserted by multiple sets of guide plates 17 and guide grooves 18. The inclined groove 3 at the bottom of the insertion tube 2 abuts against multiple sets of push blocks 6 and pushes the push blocks 6 to move outward. At the same time, it pushes the push rod 5 to extend outward and pushes the insertion rod 4 to rotate, so that the insertion rod 4 is inserted obliquely into the soil. Then, the rotating sleeve 14 is rotated to drive the push sleeve 15 to rotate. When the rotating sleeve 14 rotates, the multiple sets of positioning grooves 27 and the arc-shaped design of the positioning blocks 24 allow the multiple sets of positioning blocks 24 to slide in the positioning grooves 27. The push sleeve 15 rotates and interacts with the multiple sets of inclined blocks 16. The sliding mechanism is activated while multiple sets of compression springs 20 push the sliding sleeve 11 to slide along the sliding rod 19, causing multiple sets of inclined blocks 16 to move to the lowest end of the push sleeve 15. At this time, the sliders 13 set on the outside of the multiple sets of locking blocks 9 slide inward along the inclined sliding groove 12 and engage in the multiple sets of locking grooves 10 to engage the insertion tube 2. Multiple sets of compression springs 25 push the positioning block 24 to abut in the positioning groove 27, applying a certain resistance to the rotating sleeve 14. Then, the cement mortar is pressurized and transported by an external cement mortar conveying device, so that the mortar is injected into the cone shell 1. Then, the cement mortar is pressurized and discharged through the discharge hole 7 and the flow hole 21, so as to evenly transport the cement mortar to the outside and bottom of the cone shell 1, thereby facilitating the reinforcement of the foundation.

[0038] More specifically, after the foundation reinforcement is completed, the rotating sleeve 14 drives the push sleeve 15 to rotate, causing multiple sets of inclined blocks 16 to move to the top of the push sleeve 15. At the same time, the inclined blocks 16 push the sliding sleeve 11 to slide along multiple sets of sliding rods 19 and compress the compression spring 20. When the sliding sleeve 11 moves, it drives the slider 13 to slide outward through multiple sets of inclined sliding grooves 12, and drives multiple sets of locking blocks 9 to disengage from the locking grooves 10, releasing the locking of the insertion tube 2. Then the insertion tube 2 can be pulled out of the conical shell 1.

[0039] In summary, during the use or operation of the overall equipment: First, the cone shell 1 is placed inside the foundation, and the insertion pipe 2 is connected to the external cement mortar delivery pipe. Then, the insertion pipe 2 is inserted into the snap-fit ​​sleeve 8 and the cone shell 1. The insertion pipe 2 is positioned and inserted by multiple sets of guide plates 17 and guide grooves 18. The inclined groove 3 at the bottom of the insertion pipe 2 abuts against multiple sets of push blocks 6 and pushes the push blocks 6 to move outward. At the same time, it pushes the push rod 5 to extend outward and pushes the insertion rod 4 to rotate, so that the insertion rod 4 is obliquely inserted into the soil. Then, the rotating sleeve 14 is rotated to drive the push sleeve 15 to rotate. When the rotating sleeve 14 rotates, the arc-shaped design of multiple sets of positioning grooves 27 and positioning blocks 24 allows the multiple sets of positioning blocks 24 to slide in the positioning grooves 27. The rotation of the push sleeve 15 and the multiple sets of positioning blocks 24 are also affected. The inclined blocks 16 slide, and at the same time, multiple sets of compression springs 20 push the sliding sleeve 11 to slide along the sliding rod 19, so that the multiple sets of inclined blocks 16 move to the lowest end of the push sleeve 15. At this time, the sliders 13 set on the outside of the multiple sets of locking blocks 9 slide inward along the inclined sliding groove 12 and engage in the multiple sets of locking grooves 10 to engage the insertion tube 2. The positioning block 24 is pushed by multiple sets of compression springs 25 to abut in the positioning groove 27, applying a certain resistance to the rotating sleeve 14. Then, the cement mortar is pressurized and transported by the external cement mortar conveying device, so that the mortar is injected into the cone shell 1. Then, the cement mortar is pressurized and flows out through the discharge hole 7 and the flow hole 21, so as to evenly transport the cement mortar to the outside and bottom of the cone shell 1, thereby facilitating the reinforcement of the foundation.

[0040] After the foundation reinforcement is completed, the rotating sleeve 14 drives the push sleeve 15 to rotate, causing multiple sets of inclined blocks 16 to move to the top of the push sleeve 15. At the same time, the inclined blocks 16 push the sliding sleeve 11 to slide along multiple sets of sliding rods 19 and compress the compression spring 20. When the sliding sleeve 11 moves, it drives the slider 13 to slide outward through multiple sets of inclined sliding grooves 12, and drives multiple sets of locking blocks 9 to disengage from the locking grooves 10, releasing the locking of the insertion tube 2. Then the insertion tube 2 can be pulled out of the conical shell 1.

For all the fixed connections mentioned above, welding is preferred.
