[0013] The technical effect of adopting the above-mentioned further solution is that the fastening ring enhances the stability of the reinforcing rib, while the inner cavity provides fixation for the casting guide ring.

[0014] Preferably, the inner wall of the casting guide ring is provided with multiple pre-embedded bolts, and the threads of the multiple pre-embedded bolts are embedded with fastening nuts.

[0015] The technical effect of adopting the above-mentioned further solution is that the fixing work is carried out by pre-embedded bolts on the inner wall of the guide ring and fastening nuts on the surface.

[0016] Preferably, the installation structure further includes: a connecting plate is movably fitted onto the surface of the connecting flange, and the surface of the connecting plate has multiple positioning holes.

[0020] Preferably, one end of each of the multiple lateral reinforcing columns is movably embedded inside the groove, and the connecting plate is positioned by means of multiple fastening nuts.

[0021] The technical effect of adopting the above-mentioned further solution is that the connecting plate is further positioned by embedding the lateral reinforcing column inside the groove, and the connecting plate is locked by using the fastening nut.

[0022] Preferably, the pile body is made of high-strength concrete, steel-concrete composite material, or composite material, and has a cylindrical or polygonal structure.

[0023] The technical effect of adopting the above-mentioned further solutions is that by using high-strength concrete, steel-concrete composite material, or composite materials to make the pile body, the overall rigidity is improved.

[0024] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0025] 1. In this utility model, the pile body is driven into the foundation in sequence by a pile driver or static pressure equipment. The conical pile tip at the bottom reduces the penetration resistance and improves construction efficiency. At the same time, the spiral reinforcement on the outer surface of the pile body increases the contact area and friction with the soil. The reinforcing ribs set in the inner wall are reinforced by the fastening ring, which enhances the overall structural strength.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0035] Example 1, such as Figure 1-4 As shown, this utility model provides a construction pile for engineering construction, including: a pile body 1 with a conical pile tip 103 at the bottom to facilitate penetration into the foundation and reduce resistance; a reinforcing structure inside the pile body 1, including an inner cavity 101 and drainage holes 1011 symmetrically located at the bottom of the inner cavity 101 for draining water accumulated inside the pile body and extending its service life; and an installation structure at the top of the pile body 1, including a fixed connecting flange 105 with multiple slots 1051 on its surface for quick positioning and connection with other pile segments or pile cap structures.

[0036] In this embodiment, the pile body 1 is driven into the foundation sequentially by a pile driver or static pressure equipment. The conical pile tip 103 at the bottom reduces the penetration resistance and improves construction efficiency. At the same time, the spiral reinforcement part 104 on the outer surface of the pile body 1 increases the contact area and friction with the soil. The reinforcing ribs 102 set in the inner wall are reinforced by the fastening ring 1021, which enhances the overall structural strength. The opening on the surface of the casting guide ring 1012 can be used for later grouting to reinforce the soil around the pile body, further improving the bearing capacity of the pile body. With the help of the drainage hole 1011, water accumulated in the pile body can be drained, extending the service life.

[0037] Example 2, as Figure 1-4 As shown, the pile body 1 has a spiral reinforcing part 104 on its outer surface to enhance the friction and anchoring performance between the pile body and the foundation. The pile body 1 has an inner cavity 101 with multiple reinforcing ribs 102 fixedly installed on its inner wall, and is laterally reinforced by fastening rings 1021 to form a stable overall structure. A casting guide ring 1012 is provided at the top of the inner cavity 101, and the inner wall is provided with pre-embedded bolts 1013 and fastening nuts 1014 for the installation of connecting components. A connecting flange 105 is provided at the top of the pile body, and a connecting plate 106 is movably fitted on its surface. The surface of the connecting plate 106 has multiple positioning holes 1061, which cooperate with the pre-embedded bolts 1013 to achieve quick positioning. Lateral reinforcing columns 1062 are provided at the four corners of the bottom of the connecting plate 106, and their ends are embedded in the grooves 1051 on the connecting flange 105 to enhance the shear resistance of the connection structure. The connecting plate 106 is locked and fixed by multiple fastening nuts 1014.

[0038] In this embodiment, the lateral reinforcing column 1062 is guided for installation through the top slot 1051. It is fitted onto the surface of the pre-embedded bolt 1013 with the positioning hole 1061. The connecting plate 106 is embedded on the surface of the connecting flange 105. The connecting plate 106 is laid flat on the ground with the help of the connecting plate 106. It is used in conjunction with the embedded anti-pull-out anchor rod to provide additional support under the action of large horizontal force or groundwater buoyancy. The connecting plate 106 is then installed with the fastening nut 1014 to enhance the overall stability.

[0039] Working principle: During use, the pile body 1 is driven into the foundation sequentially using a pile driver or static pressure equipment. The conical pile tip 103 at the bottom reduces penetration resistance and improves construction efficiency. Simultaneously, the spiral reinforcement 104 on the outer surface of the pile body 1 increases the contact area and friction with the soil. The reinforcing ribs 102 on the inner wall, reinforced by the fastening ring 1021, enhance the overall structural strength. Furthermore, the openings on the surface of the casting guide ring 1012 can be used for later grouting to reinforce the soil around the pile, further improving the pile's bearing capacity. This, combined with the drainage holes 1011... It can drain water accumulated in the pile body and extend its service life. In addition, the lateral reinforcing column 1062 is guided to be installed through the top slot 1051. It is fitted onto the surface of the pre-embedded bolt 1013 with the positioning hole 1061. The connecting plate 106 is embedded on the surface of the connecting flange 105. The connecting plate 106 is laid flat on the ground with the help of the connecting plate 106. It is used in conjunction with the embedded anti-pull-out anchor rod to provide additional support under the action of large horizontal force or groundwater buoyancy. The connecting plate 106 is then installed with the fastening nut 1014 to enhance the overall stability.
