Description
Technical Field
[0001] The utility model relates to the technical field of static pressure pile planting, in particular to a pile connection and fixing device for bamboo piles. Background Art
[0002] The construction of static drill root piles includes the following steps: S1, drilling holes at the selected pile positions; S2, expanding the lower part of the holes; S3, injecting cement slurry into the expanded part to displace the mud in the expanded part; S4, injecting cement slurry into the part of the holes other than the expanded part to displace the mud in the holes; S5, placing precast piles into the holes. The precast piles are formed by connecting precast single piles in sequence. From bottom to top, at least one section of the precast single pile is a bamboo section precast pile, and the rest are cylindrical precast piles. Use a static press to place the precast single piles into the holes section by section. When the next section of the precast single pile sinks into the holes, the static press temporarily fixes it, lifts the previous section of the precast single pile, aligns the previous section of the precast single pile with the next section of the precast single pile, and then implements the pile connection operation. After the pile connection is completed, it is lowered.
[0003] like Figure 1 As shown, the existing static press includes a frame 10, a lifting cylinder 20 and a pile clamp box 30. There are two frames 10, which are arranged at intervals and in a gantry shape. The pile clamp box 30 is arranged between the two frames 10. The pile clamp box 30 has a through hole 31 that passes through from top to bottom. The through hole 31 is used for the precast pile to pass through. Four clamps 32 are evenly distributed along the circumference of the precast pile. The pile clamp box 30 is equipped with a pile clamp cylinder 33 corresponding to the clamp 32. The pile clamp cylinder 33 is used to drive the clamp 32 to hold the precast pile passing through the through hole 31. There are two lifting cylinders 20, which are fixed to the upper side of the frame 10 in a one-to-one correspondence. The piston rod of the lifting cylinder 20 passes through the frame 10 downward and is connected to the pile clamp box 30 to drive the pile clamp box 30 to rise and fall. The pile clamping cylinder 33 drives the clamp 32 to hold the precast pile inserted into the through hole 31, and the lifting cylinder 20 drives the pile clamping box 30 to descend, so that the precast pile can be implanted into the drilled hole.
[0004] The existing static press clamp has a limited stroke and is suitable for the clamping and pressing construction of cylindrical precast piles. The outer diameter of the bamboo section of the bamboo pile is equal to the outer diameter of the cylindrical precast pile, and the outer diameter of the pile body between adjacent bamboo sections of the bamboo pile is smaller than the outer diameter of the cylindrical precast pile, so that the clamp of the pile clamp box can only be clamped on the bamboo section of the bamboo pile. The length of a single bamboo section of the bamboo pile is small, so that the contact area between the clamp and the bamboo pile is small, so that the friction between the clamp and the bamboo pile is not enough to offset the gravity of the bamboo pile, which often causes the clamp and the bamboo section of the bamboo pile to slip, posing certain safety hazards. At the same time, the bamboo section may be damaged due to excessive clamping force, which in turn affects the construction quality. Utility Model Content

[0014] By adopting the above structure, when the support plate supports the lower end of the bamboo joint of the bamboo pile, the upper end of the support plate abuts against the lower end of the bamboo joint, and the supporting range is larger, making the bamboo pile less likely to shake, thereby improving the stability of the bamboo pile when it is supported and fixed.
[0015] Optionally, the two folding mechanisms are arranged opposite to each other, and the support plate extends symmetrically from a midpoint of one end of the folding mechanism to both sides.

[0026] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.
[0027] In the embodiments of the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
[0028] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the following is a brief description of the present invention in conjunction with the attached Figure 2-4 The specific embodiment of the present application is described in detail. The direction indicated by arrow x is the length direction of the folding mechanism 40 , and the direction indicated by arrow y is the width direction of the folding mechanism 40 .
[0029] Reference Figure 2 and Figure 3 As shown, the embodiment of the present application discloses a pile connection and fixing device for bamboo piles, which is suitable for fixing bamboo piles when connected with other piles, and is particularly suitable for bamboo piles with conical surfaces at the lower ends of the bamboo joints. The pile connection and fixing device for bamboo piles includes a pile clamping box 30, two folding mechanisms 40, and two support plates 50. A through hole 31 that passes through from top to bottom is provided in the middle of the pile clamping box 30, and the through hole 31 is used for the bamboo pile to pass through from top to bottom. The two folding mechanisms 40 are both connected to the upper side of the pile clamping box 30, and the two folding mechanisms 40 are respectively located on both sides of the through hole 31, and the two support plates 50 are respectively connected to one end of the two folding mechanisms 40.
[0030] When the folding mechanism 40 is unfolded, the support plate 50 is located above the through hole 31, and a gap is formed between the two support plates 50. The gap is used for the pile body between adjacent bamboo sections of the bamboo pile to pass from top to bottom, and the support plate 50 is used to support the lower end of the bamboo section of the bamboo pile; when the folding mechanism 40 is closed, the support plate 50 leaves the through hole 31.
[0031] During the bamboo pile implantation and drilling process, before the uppermost bamboo section of the bamboo pile moves to the pile clamp box 30, the operator unfolds the folding mechanism 40 so that the support plate 50 is located above the through hole 31. A gap is formed between the two support plates 50 for the pile body between adjacent bamboo sections of the bamboo pile to pass from top to bottom. The support plate 50 is supported on the lower end of the bamboo section of the bamboo pile to support and fix the bamboo pile without the need to use the clamp 32 of the static press to clamp and fix the bamboo pile, thereby avoiding the situation where the clamp 32 holds the bamboo section too much and damages the bamboo section of the bamboo pile, or the clamp 32 holds the pile too little and slips on the pile body, thereby improving the safety of the bamboo pile and the cylindrical prefabricated pile during pile connection construction.
[0032] Further, the folding mechanism 40 includes a first plate 41, a second plate 42, a first pivot sleeve 43, a second pivot sleeve 44 and a rotating shaft 45. Specifically, the first plate 41 is fixed to the upper side of the pile clamp box 30, the number of the first pivot sleeve 43 is at least one, at least one first pivot sleeve 43 is fixed to the side of the first plate 41 facing the through hole 31, and the number of the first pivot sleeves 43 can be set according to actual conditions. The number of the second pivot sleeve 44 is at least one, and the number of the first pivot sleeve 43 can be set according to actual conditions, the support plate 50 is fixed to one end of the second plate 42, at least one second pivot sleeve 44 is fixed to the other end of the second plate 42, and the rotating shaft 45 is sequentially penetrated on the first pivot sleeve 43 and the second pivot sleeve 44 in the horizontal direction, so that the second plate 42 and the support plate 50 can rotate relative to the first plate 41 around the rotating shaft 45.
[0033] Furthermore, there are multiple first pivot sleeves 43 and second pivot sleeves 44, which are stacked alternately in sequence along the axial direction, and adjacent first pivot sleeves 43 and second pivot sleeves 44 abut against each other, so that the first plate 41 and the second plate 42 are not easy to slide relative to each other along the axial direction of the rotating shaft 45.
[0034] Furthermore, when the folding mechanism 40 is closed, the angle between the first plate 41 and the second plate 42 is less than 90°, so that when the folding mechanism 40 is closed, the second plate 42 and the support plate 50 can remain stable and are not easy to fall back above the through hole 31.
[0035] Furthermore, the two folding mechanisms 40 can be arranged opposite to each other or staggered; Figure 2 and Figure 3As shown, when the two folding mechanisms 40 are arranged opposite to each other, the direction of the force applied by the bamboo stake to the support plate 50 is perpendicular to the rotating shaft 45 of the folding mechanism 40, so that the force applied by the bamboo stake to the support plate 50 acts evenly on the rotating shaft 45 of the folding mechanism 40, and the rotating shaft 45 is not easy to bend due to uneven force. When the two folding mechanisms 40 are arranged in a staggered manner, the opening of the support plate 50 is arranged toward one side of the second plate 42; when the support plate 50 supports and fixes the bamboo stake, the direction of the force applied by the bamboo stake to the support plate 50 is set at an acute angle to the included angle of the rotating shaft 45 of the folding mechanism 40, and the force applied by the bamboo stake to the support plate 50 acts unevenly on the rotating shaft 45 of the folding mechanism 40, that is, the force at one end of the rotating shaft 45 is large and the force at the other end is small, which easily causes the rotating shaft 45 of the folding mechanism 40 to bend and deform, affecting the normal rotation of the folding mechanism 40. In this embodiment, the two folding mechanisms 40 are introduced as an example of being arranged opposite to each other.
[0036] Furthermore, the support plate 50 is arranged in an arc shape, and the inner diameter of the support plate 50 is larger than the outer diameter of the pile body between the adjacent bamboo sections of the bamboo section pile and smaller than the maximum diameter of the bamboo section of the bamboo section pile. When the folding mechanism 40 is unfolded, the upper end of the support plate 50 is arranged horizontally, and the two support plates 50 are arranged coaxially. In this arrangement, when the support plate 50 supports the lower end of the bamboo section of the bamboo section pile, the corners of the upper end surface and the inner side wall of the support plate 50 are both in contact with the lower end of the bamboo section of the bamboo section pile, and the support range is large, so that the bamboo section pile is not easy to shake when supported by the support plate 50, and the stability of the bamboo section pile when supported is improved.
[0037] Further, refer to Figure 4 A supporting cone surface 51 is provided on the upper part of the inner wall of the supporting plate 50, and the inner diameter of the supporting cone surface 51 gradually decreases from top to bottom; when the two folding mechanisms 40 are unfolded, the supporting cone surface 51 can fit together with the cone surface at the lower end of the bamboo joint of the bamboo joint pile to increase the contact area between the supporting plate 50 and the bamboo joint pile, so that the bamboo joint pile is not easy to shake when supported by the supporting plate 50, further improving the stability of the bamboo joint pile when supported.
[0038] Further, refer to Figure 2 and Figure 3 The support plate 50 extends symmetrically from the midpoint of one end of the folding mechanism 40 to both sides, that is, the support plate 50 extends symmetrically from the midpoint of one end of the second plate 42 in the width direction to both sides, so that the support force provided by the support plate 50 for the bamboo pile is symmetrically distributed, so that the bamboo pile can be kept in a vertical state when supported and fixed by the support plate 50, which is convenient for splicing and connecting the bamboo pile with the cylindrical prefabricated pile. The movement trajectories of the two support plates 50 do not cross during the unfolding process of the folding mechanism 40, so that the two support plates 50 will not interfere with each other during the unfolding process of the folding mechanism 40, ensuring smooth operation of the bamboo pile connection and fixing device.
[0039] Furthermore, a flexible pad 60 is connected to the upper end of the support plate 50. The flexible pad 60 is made of a flexible material such as rubber. The flexible pad 60 can be fixed to the support plate 50 by rivets or glue. When the support plate 50 supports the lower end of the bamboo section of the bamboo section pile, the flexible pad 60 separates the support plate 50 from the lower end of the bamboo section of the bamboo section pile, reduces the rigid collision between the bamboo section pile and the support plate 50, and protects the bamboo section pile.
[0040] Furthermore, the flexible pad 60 covers the upper end, inner side wall and lower end of the support plate 50 , so that the operator is not easily scratched when grasping the support plate 50 , and it is convenient for the operator to grasp the support plate 50 to rotate and unfold or close the folding mechanism 40 .
[0041] During the bamboo pile implantation and drilling process, before the uppermost bamboo of the bamboo pile moves to the pile clamp box 30, the operator unfolds the folding mechanism 40, the second plate 42 abuts against the upper side of the top wall of the pile clamp box 30 horizontally, and the support plate 50 is located above the through hole 31; the bamboo pile continues to be implanted in the drilled hole until the uppermost bamboo part of the bamboo pile abuts against the upper sides of the two support plates 50, supporting and fixing the bamboo pile. After that, the pile driver crane is operated to lift the cylindrical prefabricated pile to the top of the bamboo pile, and the piles are connected after alignment. After the bamboo pile is connected with the cylindrical prefabricated pile above it, the cylindrical prefabricated pile is lifted upward for a distance by the pile driver crane, so that the uppermost bamboo part of the bamboo pile is separated from the support plate 50, the folding mechanism 40 is closed, and then the pile implantation operation is continued.
[0042] In addition, four clamps 32 are evenly distributed along the circumference of the precast pile in the through hole 31, and a clamping cylinder 33 corresponding to the clamp 32 is installed on the inner wall of the through hole 31 of the pile clamp box 30. The clamping cylinder 33 is used to drive the clamp 32 to hold the precast pile passing through the through hole 31. The clamping cylinder 33 cooperates with the clamp 32 to hold and fix the cylindrical precast pile, and the folding mechanism 40 cooperates with the support plate 50 to support and fix the bamboo pile. The two cooperate to complete the pile planting construction of the precast pile, avoiding the situation where the clamp 32 holds too much pressure to damage the bamboo part of the bamboo pile, or the clamp holds too little pressure to slip the clamp and the bamboo pile body, thereby improving the safety of the bamboo pile and the cylindrical precast pile during the pile connection construction.
[0043] Although the disclosure is disclosed as above, the protection scope of the disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the disclosure, and these changes and modifications will fall within the protection scope of the present invention.
