Description

Technical Field

[0001] The present invention belongs to the technical field related to water conservancy projects, and more specifically, particularly relates to a strong vibration liquefaction foundation strong compaction reinforcement device and method thereof. Background Art

[0002] The reinforcement treatment of the foundation of the clay core gravel dam of the water intake hub is a comprehensive project, which aims to improve the bearing capacity and stability of the foundation and ensure the safe operation of the dam. As an important water conservancy engineering structure, the stability of the foundation of the clay core gravel dam is directly related to the safety and durability of the entire dam. Therefore, strengthening the foundation is a key step to ensure the normal operation of the dam and extend its service life. However, the foundation tamping reinforcement device in the prior art has the following defects:

[0003] 1. In the existing technology, the current treatment principle for liquefied foundations is to increase the density of the soil layer and improve the conditions for removing pore water, thereby improving its ability to resist liquefaction. The commonly used method is dynamic tamping reinforcement. Dynamic tamping is a foundation reinforcement method first invented by the French company Menard. This method uses a 10-40t rammer of a dynamic tamping machine and a drop distance of 10-40m to impact and vibrate the foundation soil, thereby increasing the strength of the soil and reducing its compressibility. However, in the process of the dynamic tamping device hammering the liquefied foundation, soil will accumulate in the air vents of the rammer, so that the staff needs to clean it after tamping several times, which leads to a decrease in the efficiency of dynamic tamping reinforcement construction;

[0004] 2. In the prior art, when the rammer of the foundation tamping reinforcement device touches the ground, the local air of the part where the rammer touches the ground will be strongly compressed, and then a highly diffusive air wave or shock wave will be generated, thereby causing the debris of the liquefied foundation to splash at high speed. At this time, part of the gas and debris are discharged through the exhaust hole, which may easily cause the debris to injure the workers, posing a serious safety hazard;

[0005] 3. In the prior art, when the rammer of the foundation compaction reinforcement device is working, a huge noise will be generated when the rammer collides with the gravel on the liquefied foundation, which will not only easily disturb the normal life of the surrounding residents, but also cause hearing damage to the construction workers on site in the long run. In addition, since the rammer generally has a considerable weight, it will also be subjected to a huge reaction force from the liquefied foundation when compacting the land. Long-term vibration and impact can easily cause the rammer to have major or minor failures, thereby reducing construction efficiency.

[0006] Therefore, in view of this, the existing structure and defects are studied and improved, and a strong vibration liquefaction foundation compaction reinforcement device and method are provided, in order to achieve a more practical and valuable purpose. Summary of the invention

[0054] Preferably, a strong vibration liquefaction foundation strong compaction reinforcement method comprises the following steps:

[0055] S1: Clean the foundation, remove debris and gravel on the surface of the foundation, and ensure the flatness and cleanliness of the foundation surface;

[0056] S2: Compact the foundation, using vibration compaction or rolling to compact the gravel foundation to reduce the gaps between particles and improve the density and bearing capacity of the foundation;

[0057] S3: Laying gravel layer: Lay a layer of gravel or crushed stone of appropriate thickness on the foundation to form a uniform foundation layer;

[0058] S4: Grouting reinforcement: For weak interlayers or cracks in the foundation, grouting reinforcement can be used; by injecting cement slurry or other solidifying materials, the weak strata are reinforced to improve the overall strength of the foundation;

[0059] S5: Set up anti-seepage structures. In order to prevent groundwater from eroding and penetrating the foundation, anti-seepage structures can be set up in the foundation, such as anti-seepage walls, anti-seepage curtains, etc.

[0060] S6: Drainage treatment. The gravel foundation has good drainage performance, but it also needs reasonable drainage treatment. By setting up drainage ditches, drainage wells and other drainage facilities, the accumulated water in the foundation can be discharged in time to reduce the moisture content and seepage pressure of the foundation and improve the stability of the foundation.

[0061] S7: Monitoring and maintenance. After the foundation reinforcement is completed, the foundation needs to be monitored and maintained for a long time. By regularly testing the settlement, deformation and other indicators of the foundation, potential problems can be discovered and dealt with in a timely manner to ensure the stability and safety of the foundation.

[0062] Specific use of the present invention:

[0063] The reinforcement of the foundation of the clay core gravel dam of the water intake hub is a complex and important project. Through the implementation of a series of measures such as cleaning the foundation, compacting the foundation, reinforcing the foundation, drainage treatment, monitoring and maintenance, the bearing capacity and stability of the foundation can be significantly improved to ensure the safe operation of the dam body. When compacting the foundation, the tamping machine 10 moves above the liquefied foundation.

[0064] First, the driver 41 starts to reel in the pull rope 42, and the reeling in the pull rope 42 drives the unhooker 12 and the tamping hammer assembly to move upward. When the tamping hammer assembly rises to a certain height, the unhooker 12 starts to loosen the lifting lug 19, and the tamping hammer assembly starts to fall. The bottom plate 23 first contacts the liquefied foundation, and the bottom plate 23 cooperates with the cylinder 24 and the through-port 39 to prevent the liquefied foundation soil from entering the second exhaust hole 25. At this time, the bottom plate 23 drives the cylinder 24 and the force transmission rod 22 to move upward due to the reaction force of the liquefied foundation, until the bottom of the pressure plate 15 directly hammers the liquefied foundation. Among them, during the upward movement of the cylinder 24, the gas first enters the interior of the cylinder 24 through the through-port 39, and the gas is then discharged through the several through-holes 38 on the round cover 21. The force transmission rod 22 moves upward to stretch the rubber part 40 to produce an elastic force.

[0065] Secondly, the staff puts the lifting lug 19 into the unhooking device 12, and then the unhooking device 12 starts to clamp and fix the lifting lug 19. Next, the driver 41 starts to reel in the pull rope 42, and the reeling of the pull rope 42 drives the unhooking device 12 and the tamping hammer assembly to move upward. The tamping hammer body 13 moves upward, and the elastic force generated by the compression of the rubber member 40 and the inertia of the bottom plate 23 make the bottom plate 23 temporarily stay on the liquefied foundation until the bottom plate 23 returns to the initial state, so that the bottom plate 23 is out of contact with the liquefied foundation.

[0066] At the same time, the first elastic hollow pieces 31 and the first elastic cross pieces 32 are compressed to generate elastic force to separate the tamping hammer body 13 from the pressing plate 15. The second elastic hollow pieces 35 and the second elastic cross pieces 36 are compressed to generate elastic force to move the T-shaped rod 33 downward in the slide groove 34 to reset, and after moving to a predetermined height, it is hammered downward again, and the movement is repeated to compact the liquefied foundation.

[0067] Next, a layer of gravel or crushed stone of appropriate thickness is laid on the foundation to form a uniform base layer. This helps to increase the bearing capacity and stability of the foundation.

[0068] Then, for the weak interlayers or cracks in the foundation, grouting reinforcement can be used. By injecting cement slurry or other solidifying materials, the weak strata can be reinforced to improve the overall strength of the foundation.

[0069] Finally, in order to prevent groundwater from eroding and penetrating the foundation, anti-seepage structures can be set up in the foundation, such as anti-seepage walls, anti-seepage curtains, etc. These structures can effectively cut off the seepage path of groundwater and protect the foundation from erosion.

[0070] A strong vibration liquefied foundation tamping reinforcement device and method of the present invention are provided with a tamping hammer assembly, and the bottom plate 23, cylinder 24 and through port 39 in the tamping hammer assembly are used to prevent the liquefied foundation soil from entering the second exhaust hole 25, and the gas can be discharged through the through port 39 and the through hole 38; then, by adjusting the number of the plurality of counterweight blocks 17 on the cover plate 16 and the tamping hammer body 13, the weight of the tamping hammer assembly can be adjusted as needed; finally, the force transmission rod 22 is moved up and down to drive the L-shaped rod 44 and the rubber protrusion 45 up and down, so that the impurities blocked in the through hole 38 can be cleaned by the rubber protrusion 45, which is beneficial to maintaining the exhaust effect of the plurality of through holes 38.

[0071] A strong vibration liquefaction foundation strong compaction reinforcement device and method of the present invention firstly uses a first sound-absorbing sponge 26 to be located on the outer side between the strong compaction hammer body 13 and the pressure plate 15, thereby silencing the noise generated by the contact between the strong compaction hammer body 13 and the pressure plate 15; then a plurality of second sound-absorbing sponges 27 are respectively located in a plurality of through holes 38, thereby further silencing the noise; then an elastic net 28 is used to intercept air waves and debris, thereby reducing the movement speed of the air waves and debris; finally, a round cover 21 cooperates with a plurality of second sound-absorbing sponges 27 to further intercept air waves and debris, thereby preventing the debris from quickly splashing through the through holes 38 and injuring workers, thereby eliminating safety hazards.

[0072] The invention discloses a strong vibration liquefied foundation strong compaction reinforcement device and method thereof. First, a plurality of first elastic hollow pieces 31 and a first elastic cross piece 32 cooperate to reduce the shock between the pressure plate 15 and the strong compaction hammer body 13. Then, the first rubber layer 29 and the second rubber layer 30 contact each other, thereby providing a buffer between the pressure plate 15 and the strong compaction hammer body 13 and reducing the noise generated by the contact between the strong compaction hammer body 13 and the pressure plate 15. Then, the T-shaped rod 33 slides in the slide groove 34 to extrude and deform the second elastic hollow piece 35 and the second elastic cross piece 36, thereby strengthening the T-shaped rod 33 and the strong compaction hammer body 13. The shock absorbing effect is performed between the hammer body 13, which is beneficial to improving the shock absorbing effect between the pressure plate 15 and the ramming hammer body 13; finally, the T-bar 33 slides in the slide groove 34 to make the third rubber layer 37 contact the slide groove 34, thereby performing a buffering effect between the T-bar 33 and the ramming hammer body 13, which is beneficial to improving the buffering effect between the pressure plate 15 and the ramming hammer body 13 and can further reduce the noise generated by the contact between the ramming hammer body 13 and the pressure plate 15, effectively absorbing the reverse impact force and vibration force from the liquefied foundation, thereby reducing the frequency of failure of the ramming hammer assembly due to impact vibration during long-term operation.

Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
