[0027] In a specific embodiment of the present invention, the insertion assembly 2 includes an adjusting seat 21 that is slidably sleeved on the ground pile stud 1, and the adjusting seat 21 is provided with an installation hole corresponding to the adjustment hole 121 for installing the locking bolt 3; the bottom of the adjusting seat 21 is provided with a clamping platform 211, and a fixed platform 22 is rotatably sleeved on the clamping platform 211, and the fixed platform 22 is provided with a limiting groove 221 for installing the clamping platform 211, and a cover plate 23 fixedly connected to the fixed platform 22 is abutted above the clamping platform 211, and the cover plate 23 is used to limit the clamping platform 211 in the vertical direction; a plurality of insertion rods 24 are provided at equal intervals around the bottom of the fixed platform 22.

[0028] In this embodiment, a preload spring 25 is fixedly connected to the bottom of the fixing platform 22, and the preload spring 25 is sleeved on the ground pile stud 1. The clamping platform 211 and the fixing platform 22 are rotatably connected via a bearing.

[0029] In a specific embodiment of the present invention, a connecting groove 41 for installing the fixing seat 5 is provided on the top of the connecting seat 4, and a number of sliding grooves 42 are provided at equal intervals on the side walls of the connecting groove 41. A clamping block 43 is horizontally slidably installed in any sliding groove 42, and a clamping groove 51 that engages with the clamping block 43 is provided on the fixing seat 5; the clamping block 43 is provided with an inclined surface at one end close to the fixing seat 5 for facilitating the insertion of the fixing seat 5, and a telescopic spring 44 is abutted at the other end, and the telescopic spring 44 is installed in the sliding groove 42; a pull rope 45 is also provided at the end of the clamping block 43 away from the fixing seat 5, and the pull rope 45 passes through the connecting seat 4 and is connected to the pull ring 46, and a clamping column 47 for engaging with the pull ring 46 is provided on the side of the connecting seat 4.

[0030] In this embodiment, the top of the clamping base 5 is provided with a polygonal mounting groove 52. A fastening bolt 53 is also connected to the clamping base 5, which passes horizontally through the clamping base 5 and is secured to the clamping nut. The connecting base 4 has a through-hole for the pull cord 45, and the pull ring 46 has a larger diameter than the through-hole. Any device that can achieve the aforementioned properties and functions of the clamping base 5 and pull ring 46 is within the scope of protection of this application.

[0031] Compared with the prior art, this easy-to-install steel spiral ground pile can determine the insertion depth before construction by adjusting the position of the adjustment portion 12 of the plug-in assembly 2 in the ground pile stud 1. During construction, the spiral ground pile only needs to be inserted until the plug-in assembly 2 contacts the ground and the rotation and pressing operation can be stopped to complete the installation of the spiral ground pile. The installation process does not require manual measurement, the construction process is simpler and more convenient, and construction efficiency is effectively improved. By setting the detachable connection between the connecting seat 4 and the clamping seat 5, the clamping seat 5 that adapts to the installation groove 52 can be installed according to the shape of the construction facility. The disassembly and assembly are convenient and quick, and the clamping seat 5 can be reused. In addition, the setting of the preload spring 25 can provide a certain preload force to the ground pile stud 1 after installation, which can better resist external forces and ensure the stability of the installation. By setting the rotational connection between the adjustment seat 21 and the fixed platform 22, the fixed platform 22 can be pressed into the ground a certain distance during the rotation process. The construction operations will not interfere with each other. Only one rotation and pressing force needs to be applied. No additional construction is required, and the operation is simple.

[0032] The working process of the steel spiral ground pile of the present invention, which is easy to install, is as follows: according to the required depth of screwing into the ground, the position of the adjustment seat 21 on the ground pile stud 1 is adjusted, the adjustment seat 21 is aligned with the adjustment hole 121 at the corresponding position, and the locking bolt 3 is passed through the adjustment seat 21 and locked and fixed in the adjustment hole 121. The adjustment hole 121 is a threaded hole. The clamping seat 5 having a mounting groove 52 adapted to the joint of the rotary pressing machine is inserted into the connecting seat 4. During insertion, the bottom of the clamping seat 5 pushes the clamping block 43 into the sliding groove 42 through the inclined surface on the clamping block 43. When the clamping slot 51 is moved to align with the clamping block 43, the clamping block 43 is pushed into the clamping slot 51 under the action of the telescopic spring 44 and engages with the clamping slot 51, thereby completing the installation of the clamping seat 5 and the connecting seat 4. After the rotating pressing machine is engaged with the mounting slot 52 on the clamping seat 5, it rotates and presses down the spiral pile. When the insertion rod 24 at the bottom of the fixed platform 22 is half inserted into the ground, the pressing is stopped. At this time, the pre-tightening spring 25 is in a compressed state, achieving the pre-tightening effect. The insertion rod 24 is inserted into the ground, providing a certain support force and a certain grip to ensure installation stability.

[0033] If the structure of the bottom of the workpiece to be installed is compatible with the installation groove 52, the workpiece is directly inserted into the installation groove 52, and the fastening bolt 53 is passed through the clamping base 5 and the workpiece to complete the fixed connection. If the structure of the bottom of the workpiece is not compatible with the installation groove 52, the pull rope 45 is pulled through the pull ring 46 to separate the clamping block 43 from the clamping groove 51, and the pull ring 46 is locked on the clamping column 47. After all the pull rings 46 are engaged, the clamping base 5 is taken out and replaced with a clamping base 5 with an installation groove 52 that is compatible with the workpiece and installed in the connecting groove 41. All the pull rings 46 are separated from the clamping column 47, so that the clamping block 43 is locked and fixed with the new clamping base 5, and then the workpiece is installed.

[0034] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. Reference can be made to the common and similar parts between the various embodiments. For the devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the method description.
