Description

Technical Field

[0001] The utility model relates to the technical field of gravel piles, in particular to a reinforced vibro-impact gravel pile. Background Art

[0002] Gravel piles are composite foundation reinforcement piles made of gravel (pebbles) as the main material. Gravel piles and sand piles are collectively referred to as loose piles or coarse-grained soil piles abroad. The so-called loose piles refer to piles without bonding strength. The composite foundation composed of loose piles such as gravel columns or sand piles and soil between piles can also be called loose pile composite foundation. The composite foundations such as gravel piles, sand piles, and slag piles widely used at home and abroad are all loose pile composite foundations. Vibroflotation refers to a foundation treatment method in which the loose foundation soil layer is vibrated and compacted under the combined action of horizontal vibration of the vibrator and high-pressure water or assisted by high-pressure air, or after forming holes in the foundation soil layer, hard coarse-grained materials with stable performance are backfilled to form a reinforcement body (vibratory pile) after vibration compaction, and the reinforcement body and the surrounding foundation soil form a composite foundation.

[0003] Traditional vibro-stone piles are cylindrical and have poor bonding with the strata. The overall stability and shear strength of vibro-stone piles need to be strengthened. There are also studies that expand vibro-stone piles in a drum shape to increase the contact surface between the vibro-stone piles and the foundation, while enhancing the degree of interaction between the two. Under the condition that the force meets the design requirements, the reinforcement effect is enhanced to achieve the purpose of improving the vibro-stone piles in poor foundation treatment. However, according to the existing construction method, the hole is expanded at the expansion part of the vibro-stone pile, and then fillers are directly added. The expansion part is prone to collapse, which affects the quality of the pile. In addition, the hole is only expanded locally in the vibro-stone pile, and the pile shape is irregular, resulting in uneven force on the pile body. Utility Model Content

[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0029] The following is further described in conjunction with specific embodiments. Figure 1-Figure 3As shown, the utility model is a reinforced vibro-stone pile, referring to Figure 1 , including an outer pile 1, a reinforcing rib 2, a reversal component 3 and a driving component 4. The personnel vertically place the outer pile 1 into a pile hole drilled in advance, and then pour gravel into the inner cavity of the outer pile 1 to form a gravel pile. The reinforcing rib 2 is arranged on the peripheral wall of the outer pile 1 along the axis of the outer pile 1, and the reinforcing rib 2 is provided with multiple and distributed circumferentially along the axis of the outer pile 1. The reversal component 3 is installed on the reinforcing rib 2, and the reversal component 3 is opened by the driving component 4 to limit the reverse sliding of the outer pile 1.

[0030] In the present application, two reinforcing ribs 2 are preferably provided, which are symmetrically arranged along the axis of the outer pile 1. When the outer pile 1 is placed in the pile hole, in order to facilitate the insertion of the reinforcing rib 2 into the foundation, the side of the reinforcing rib 2 close to the insertion end of the outer pile 1 is an inclined surface, and the inclined surface of the reinforcing rib 2 gradually inclines toward the axis direction of the outer pile 1 in the installation direction of the outer pile 1.

[0031] The reversal component 3 includes an anti-reversal plate 31. A mounting groove is provided on the vertical side wall of the reinforcing rib 2. The anti-reversal plate 31 is located in the mounting groove and is elastically rotatably connected to the side wall of the mounting groove. The rotation axis is perpendicular to the axis of the outer pile 1. Under normal circumstances, the anti-reversal plate 31 is located in the mounting groove. When the driving component 4 drives the anti-reversal plate 31 to rotate out of the mounting groove, the angle between the anti-reversal plate 31 and the outer wall of the reinforcing rib 2 is toward the side of the outer pile 1 away from the insertion end. In the present application, a plurality of anti-reversal plates 31 are provided, which are installed on the two vertical side walls where the reinforcing rib 2 contacts the outer pile 1, and are distributed along the axial direction of the outer pile 1. The anti-reversal plates 31 on the two side walls are symmetrically arranged. At the same time, a plurality of mounting grooves are also provided. An anti-reversal plate 31 is provided in one mounting groove, and two mounting grooves at the same horizontal height are connected to each other.

[0032] In order to drive the anti-reversal plate 31 to rotate, the driving assembly 4 includes a plurality of first connecting rods 41. One side of the anti-reversal plate 31 located on the inner side of the reinforcing rib plate 2 is gradually inclined toward the inner side of the reinforcing rib plate 2 in the installation direction of the outer pile 1. The first connecting rod 41 slides on the outer pile 1 along the axis direction of the outer pile 1 and is vertically arranged along the axis of the outer pile 1. The rod wall at one end of the first connecting rod 41 contacts the inclined surface of the anti-reversal plate 31, and the other end extends into the outer pile 1. Since the horizontal distance between the inclined surface of the anti-reversal plate 31 and the axis of the first connecting rod 41 gradually decreases in the installation direction of the gravel pile, the first connecting rod 41 will gradually push the anti-reversal plate 31 to rotate toward the side away from the axis of the first connecting rod 41 during the vertical downward sliding process.

[0033] Since the two anti-reversal plates 31 on one reinforcing rib plate 2 are symmetrically arranged at the same level, a first connecting rod 41 is provided between the two anti-reversal plates 31 on one reinforcing rib plate 2 at the same level, and the two anti-reversal plates 31 are driven to rotate by the first connecting rod 41;

[0034] In order to drive the first connecting rod 41 on each reinforcing rib 2 to slide simultaneously, the driving assembly 4 also includes two connecting plates 42 and a second connecting rod 43. All the first connecting rods 41 on a reinforcing rib 2 are fixedly connected to a connecting plate 42. The second connecting rod 43 is located inside the outer pile 1 and is vertically arranged, and slides along the axial direction of the outer pile 1. The two connecting plates 42 are fixedly connected to the second connecting rod 43. When the anti-reversal plate 31 is in normal state, the two ends of the second connecting rod 43 are respectively flush with the two ends of the outer pile 1.

[0035] In order to seal the two ends of the outer pile 1, the reinforced vibro-stone pile also includes two pile heads 5. The two ends of the outer pile 1 are each connected with a pile head 5 through a flange.

[0036] In order to increase the length of the pile body, multiple outer piles 1 are spliced ​​end to end in the circumferential direction of the outer piles 1. The specific splicing method is through flange splicing, and the reinforcing ribs 2 on the two outer piles 1 are on the same vertical plane.

[0037] In order to ensure that the two second connecting rods 43 on the two external piles 1 are coaxial when the two external piles 1 are spliced ​​together, the second connecting rod 43 is coaxially arranged with the external pile 1 .

[0038] In order to prevent the substances in the foundation from damaging the gap and bolts when the two outer piles 1 are connected by flanges, a sealing ring 6 is bonded to the outer side of the flange connecting the two outer piles 1.

[0039] After multiple external piles 1 are inserted into the pile holes, a gap is left between the upper reinforcing rib 2 on the bottom external pile 1 and the reinforcing rib 2 of the adjacent upper external pile 1. In order to fill the gap, pouring holes 11 with the same number as the reinforcing ribs 2 are opened on the external pile 1. The pouring holes 11 are located on the side of the reinforcing rib 2 close to the insertion end of the external pile 1 and directly below the reinforcing rib 2.

[0040] In order to prevent the material in the foundation from entering the outer pile 1 from the pouring port 11 when the outer pile 1 is inserted, a blocking plate 12 is provided at each pouring port 11. The blocking plate 12 slides on the outer pile 1 along the axial direction of the outer pile 1, and each blocking plate 12 is fixedly connected to the second connecting rod 43 through a connecting rod. When the anti-reversal plate 31 is in normal state, the blocking plate 12 blocks the pouring port 11.

[0041] The working process of this embodiment is as follows: after the construction personnel splice multiple external piles 1 through flanges, the insertion end of the external pile 1 inserted into the pile hole first connects the pile head 5 with the external pile 1 through the flange, and then the gaps at the connection between the external pile 1 and the external pile 1, and the external pile 1 and the pile head 5 are wrapped by the sealing ring 6, and then the multiple external piles 1 are pressed into the pile hole by the vibrating machine. During the process of pressing the external pile 1 into the pile hole, the reinforcing rib 2 is inserted into the side wall of the pile hole. After the external pile 1 is completely pressed into the pile hole, the second connecting rod is pressed. 43, the second connecting rod 43 drives the first connecting rod 41 to move vertically downward, and rotates the anti-reverse plate 31 out of the installation groove. During the rotation of the anti-reverse plate 31, the blocking plate 12 moves vertically downward, the pouring port 11 is opened, and then gravel is poured in. During the pouring of gravel, it flows from the pouring port 11 into the gap between the two reinforced inner plates in the vertical direction to fill the gap. After the pouring of gravel is completed, the pile head 5 is installed on the top of the topmost outer pile 1 to complete the pouring of the gravel pile.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
