[0048] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further introduced in detail below in conjunction with the accompanying drawings.

[0049] See Figures 1 to 5 as shown;

[0050] This embodiment discloses a pipe pile anti-falling fixture for a pilot hole hammer-driven pile. The anti-falling fixture is used to clamp and fix the lower part of the pipe pile, and the anti-falling fixture is placed directly above the pile hole;

[0051] The anti-falling fixture includes:

[0052] A fixed support frame 1, and a through hole 105 with a size larger than the size of the pile hole is constructed in the middle area of the fixed support frame 1; and

[0053] A fixed fixture 2 installed on the fixed support frame 1;

[0054] The fixed fixture 2 includes two independent fixture split bodies 201, and the fixture split bodies 201 are used to construct a fixture part that passes through and clamps and fixes the pipe pile;

[0055] Both sides of the fixture part of the fixed fixture 2 have installation parts, and the installation parts are positioned and fixed with the fixed support frame 1;

[0056] The installation part is positioned and fixed with the fixed support frame 1 through the anti-opening and anti-blocking block 3 to keep the fixture part clamping and fixing the lower part of the pipe pile.

[0057] Specifically, this embodiment discloses a pipe pile anti-falling fixture used during the pile splicing process, which is divided into two parts: a fixed support frame 1 and a fixed fixture 2. Among them, the fixed support frame 1 is placed and fixed directly above the pile hole, and the through hole 105 formed thereon is aligned with the pile hole. The fixed fixture 2 is installed and fixed at the position of the through hole 105 of the fixed support frame 1, and the fixture part formed thereon is aligned with the through hole 105 and is used to clamp and fix the lower part of the pipe pile, thus ensuring that the pipe pile will not fall and providing convenient and safe construction conditions for subsequent pile splicing construction.

[0058] Preferably, the fixed support frame 1 of this embodiment is welded and fixed by I-beams.

[0059] The fixed support frame 1 includes two first I-beams 101 serving as longitudinal beams; and two second I-beams 102 serving as cross beams. The second I-beams 102 are welded and fixed between the two first I-beams 101, and the first I-beams 101 and the second I-beams 102 construct a through hole 105 in a quadrilateral structure. The fixed fixture 2 is located directly above the through hole 105.

[0060] First, this embodiment further defines the composition of the fixed support frame 1, which includes two first I-beams 101 and two second I-beams 102. Among them, the length of the first I-beam 101 is much greater than the length of the second I-beam 102. Select I-beams with appropriate lengths according to the size of the pile hole. Specifically, the length of the second I-beam 102 needs to be greater than the diameter of the pile hole to ensure that the size of the through hole 105 constructed by the fixed support frame 1 is also greater than the sizes of the pile hole and the fixture part.

[0061] Preferably, the fixture split body 201 of this embodiment includes a semi-cylindrical body 202 located in the middle; and straight plate bodies 203 protruding from both ends of the semi-cylindrical body 202. The semi-cylindrical bodies 202 of the two fixture split bodies 201 form the fixture part, and the corresponding straight plate bodies 203 of the two fixture split bodies 201 are close to each other and are connected by high-strength bolts 205.

[0062] Among them, the fixture part of this embodiment is located directly above the through hole 105, and the straight plate body 203 overlaps on the first I-beam 101.

[0063] A first sunk groove 103 is opened at the position where the first I-beam 101 cooperates with the straight plate body 203. The straight plate body 203 is located in the first sunk groove 103, and the anti-opening block 3 is embedded in the first sunk groove 103 and abuts against the inner wall of the straight plate body 203 and the first sunk groove 103 to maintain the relative position of the two fixture split bodies 201.

[0064] In addition, a rib plate 204 is welded and fixed to the straight plate body 203 of this embodiment, and the rib plate 204 is welded and fixed to the lower part of the straight plate body 203. A high-strength bolt 205 is installed at the middle position of the straight plate body 203, and the high-strength bolt 205 is a high-strength bolt 205 with a specification of M20.

[0065] An avoidance groove 301 is provided at the position where the anti-opening and blocking block 3 cooperates with the high-strength bolt 205, and the lower part of the anti-opening and blocking block 3 is supported on the rib plate 204.

[0066] In this embodiment, the usage modes of the fixed fixture 2 and the anti-opening and blocking block 3 for maintaining the relative position of the fixed fixture 2 to clamp the pipe pile are further defined; wherein, the fixed fixture 2 is composed of two fixture split bodies 201, and each fixture split body 201 includes a semi-cylindrical body 202 and two straight plate bodies 203. Among them, the semi-cylindrical bodies 202 form the fixture part of this embodiment. The semi-cylindrical bodies 202 with appropriate sizes are designed according to the size of the pipe pile and can clamp the pipe pile in the combined state; while the straight plate bodies 203 extend to both sides and overlap in the first sinking groove 103 of the first I-beam 101. In this embodiment, rib plates 204 are arranged at the lower part of the straight plate bodies 203. On the one hand, the structural strength of the straight plate bodies 203 can be improved, and on the other hand, the above-mentioned anti-opening and blocking block 3 can be supported.

[0067] First of all, the straight plate body 203 is placed in the middle position of the first sinking groove 103, and it can move along the first sinking groove 103 to open or close the two fixture split bodies 201. When the two fixture split bodies 201 are in a closed state, the space between the straight plate body 203 and the inner wall of the first sinking groove 103 is the space for installing the anti-opening and blocking block 3. Therefore, this embodiment can design anti-opening and blocking blocks 3 with various specifications and sizes to adapt to the use after clamping different specifications of pipe piles.

[0068] The specific usage mode is as follows: when the fixture part clamps the pipe pile, first install the high-strength bolt 205 to tightly connect the two fixture split bodies 201; subsequently, select a suitable anti-opening and blocking block 3 and embed it into the first sinking groove 103 and support it on the rib plate 204. At the same time, the relative position of the two fixture split bodies 201 can be further maintained by the two ends of the anti-opening and blocking block 3 respectively abutting against the straight plate body 203 and the inner wall of the first sinking groove 103, thereby effectively avoiding the separation of the two fixture split bodies 201 due to the accidental falling off of the thread of the high-strength bolt 205 and ensuring that the pipe pile can always be clamped and fixed by the fixture split bodies 201.

[0069] In order to facilitate the removal of the anti-opening and blocking block 3, a lifting lug 302 is welded and fixed on the upper part of the anti-opening and blocking block 3 of this embodiment, and tools such as a crowbar can be used to pry open the anti-opening and blocking block 3 by using the lifting lug 302.

[0070] In order to further ensure that both ends of the first I-beam 101 of the fixed support frame 1 in the length direction extend to the outside of the second I-beam 102 to form an extension part;

[0071] An anti-translation assembly 4 is arranged on the extension part of the first I-beam 101, and the fixed support frame 1 is connected to the structure around the pile hole through the anti-translation assembly 4.

[0072] Among them, the anti-translation component 4 of this embodiment is configured in a C-shaped structure;

[0073] The extension part is provided with a second sinking groove 104;

[0074] The anti-translation component 4 includes an integrally formed arch part 401 and bending parts 402 on both sides of the arch part 401. The arch part 401 is embedded in the second sinking groove 104, and the bending parts 402 extend to the lower part of the extension part and are connected to the structure around the pile hole through fasteners.

[0075] This embodiment further defines the structure and fixing principle of the anti-translation component 4. By embedding the arch part 401 into the second sinking groove 104 and using fasteners to fix the lower bending parts 402 to the building foundation around the pile hole, the anti-translation of the fixed support frame 1 during construction can be prevented in a limiting and clamping manner, further improving safety.

[0076] Preferably, the opening width on one side of the through hole 105 of this embodiment is greater than the diameter of the pipe pile, and the difference between the opening width on one side of the through hole 105 and the diameter of the pipe pile is 100 mm. The length of the first I-beam 101 is 3 times the opening width on one side of the through hole 105. Since the through hole 105 is a square through hole, its opening size can be measured based on the opening width on one side.

[0077] In the above technical solution, a pipe pile anti-falling fixture for a pilot hole hammer-driven pile provided by the present invention has the following beneficial effects:

[0078] The anti-falling fixture of the present invention includes a fixed support frame 1 and a fixed fixture 2. During the pile splicing process, the fixed support frame 1 is fixed above the pile hole, and then the lower part of the pipe pile is clamped and fixed by the fixed fixture 2. The fixed fixture 2 is positioned by high-strength bolts 205 and anti-opening and blocking blocks 3, effectively preventing the pipe pile from falling and improving the safety during the construction process.

[0079] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
