[0002] The building engineering spiral construction pile is a type of pile foundation. It is a pile that is planted into the ground by a special construction equipment in a spiral drilling manner. In the construction process, the pile body rotates into the ground like a screw, and the pile body is generally cylindrical with spiral blades on the outer surface. However, under different geological conditions and building requirements, different pile lengths are required. For example, in some complex geological structures, the upper layer may be soft soil, and the lower layer may be hard soil or rock layer. If the pile length cannot be adjusted, when the soft soil area is thick, the pile length may not be enough to stably place the pile end on the appropriate bearing layer, thereby affecting the bearing capacity of the pile. In some building engineering with strict requirements on settlement, the appropriate pile length is one of the key factors to control the settlement of the building. SUMMARY

[0003] The main purpose of the utility model is to provide a building engineering construction pile to solve the problem of different pile lengths required under different geological conditions and building requirements in the prior art.

[0010] Two first perforations are coaxially arranged at the end of the head sleeve away from the flange, at the end of the tail sleeve away from the conical shell, and at both ends of each sleeve.

[0011] Each inner tube is coaxially provided with two second perforations, and a plurality of groups of second perforations are uniformly distributed along the length direction of the inner tube.

[0012] The bolt rod is sequentially threaded through the first perforation, two second perforations at the same height and another first perforation, and connected with the nut.

[0014] Preferably, the flange is a ring body structure, and a plurality of arc-shaped holes are arranged on the circumference of the flange.

[0015] Preferably, a plurality of reinforcing ribs are arranged on the circumference of the connection between the head sleeve and the flange, and the two ends of the reinforcing ribs are fixedly connected with the bottom wall of the flange and the ring wall of the sleeve, respectively.

[0016] Preferably, a flat groove is arranged on the end of the head sleeve away from the flange, the end of the tail sleeve away from the conical shell, and the two ends of each sleeve, and the cap or nut of the bolt rod abuts against the flat groove.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. Example

[0026] like Figures 1 to 3 As shown, this embodiment provides a construction pile for building engineering, including multiple coaxial sleeves 1, a telescopic mechanism 2, and a helical blade 5. Adjacent sleeves 1 are connected by the telescopic mechanism 2, which can adjust the distance between the two sleeves 1. The telescopic mechanism 2 includes an inner tube 21, a bolt rod 22, and a nut 23. Figure 3 As shown, the end of the sleeve 1 at the head, away from the flange 3, the end of the sleeve 1 at the tail, away from the conical shell 4, and both ends of each sleeve 1 are coaxially provided with two first through holes 11. Each inner tube 21 is coaxially provided with two second through holes 210, and multiple sets of second through holes 210 are evenly distributed along the length of each inner tube 21. The bolt shank 22 passes sequentially through the first through hole 11, two second through holes 210 at the same height, and another first through hole 11 to connect with the nut 23. The end of the sleeve 1 at the head, away from the telescopic mechanism 2, is coaxially fixedly fitted with the flange 3. The flange 3 is a ring structure, as shown... Figure 1 As shown, flange 3 has multiple arc-shaped holes 31 arranged around its circumference. The end of sleeve 1 located at the tail end, away from the telescopic mechanism 2, is coaxially connected to conical shell 4, and the constricted end of conical shell 4 is located away from sleeve 1. Each sleeve 1 has a helical blade 5 fixedly arranged around its circumference on its annular wall.

[0027] The two sleeves 1 are connected by the telescopic mechanism 2, and the telescopic mechanism 2 can adjust the spacing between the two sleeves 1, thereby adjusting the overall length of the structure, and by adjusting the overall length of the structure, different requirements for pile length are met under different geological conditions and building requirements. The rotating head of the pile driver is inserted on the flange 3, the conical shell 4 is inserted on the ground, the rotating head of the pile driver is driven to rotate, the helical blade 5 is fixedly arranged on the circumferential wall of the sleeve 1, so that the structure is gradually inserted into the ground, until the multiple sleeves 1 are inserted into the land, and single pile driving is completed. The adjustable length construction pile can flexibly determine its length according to the position and bearing capacity of the original foundation, better cooperate with the original foundation, and improve the stability and bearing capacity of the entire foundation system.

[0028] As shown in Figure 2 , the conical shell 4 has a through hole 41. After the multiple sleeves 1 are inserted into the land and single pile driving is completed, the soil around the spiral pile needs to be grouted and reinforced, and the hole at the bottom can be used as a grouting channel. The slurry can penetrate into the deeper layer of the soil around the pile through these holes, more uniformly fill the soil voids, and enhance the strength of the soil and the adhesion between the soil and the pile. This way can effectively improve the bearing capacity and stability of the spiral pile, and prolong its service life. As shown in Figure 1 , a plurality of reinforcing ribs 6 are arranged circumferentially at the connection between the head sleeve 1 and the flange 3, and the two ends of the reinforcing rib 6 are fixedly connected with the bottom wall of the flange 3 and the ring wall of the sleeve 1. The arrangement of the reinforcing rib 6 increases the firmness of the flange 3 and the sleeve. The end of the head sleeve 1 away from the flange 3, the end of the tail sleeve 1 away from the conical shell 4, and the ring wall of each sleeve 1 are provided with a flat groove 7, and the cap or nut 23 of the bolt rod 22 abuts against the flat groove 7. The arrangement of the flat groove 7 helps the cap or nut 23 of the bolt rod 22 to contact the sleeve, increasing the firmness between them.

[0029] Obviously, the described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
