Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering, and in particular relates to a construction engineering pile. Background Art

[0002] Construction engineering piles are basic structural elements used to reinforce soil and support buildings; their main function is to transfer the weight of the building to a deeper, more stable soil or rock layer. Pile foundation engineering is an important branch of civil engineering, especially in soft soil areas, high-rise buildings, bridges, ports and other large structures;

[0003] Existing construction engineering piles are usually cylindrical structures. After they are driven into the soil layer, the soil around the piles is compacted or squeezed apart, and the original structure of the soil is destroyed, which may affect the foundations of surrounding buildings that have been built. By using I-shaped steel piles and H-shaped steel piles as engineering piles, the difficulty of piling will increase. For this reason, we propose a construction engineering pile. Utility Model Content

[0004] The purpose of the utility model is to provide a construction engineering pile to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a construction engineering pile, including a base, a plurality of engineering piles are fixedly installed on the bottom outer wall of the base by bolts, and a plurality of longitudinal grooves are opened on the side outer wall of the engineering pile, a hanging plate is fixedly installed on the top of the engineering pile by bolts, and a positioning groove is opened on the top outer wall of the hanging plate, a through hole is opened on the bottom inner wall of the positioning groove, an insertion hole is opened on the top of the longitudinal groove, and the insertion hole and the through hole are interconnected, and a plurality of lifting ears are fixedly installed on the top outer wall of the hanging plate by bolts.

[0006] Furthermore, a mounting groove is formed at the top of the support platform, and a cover plate is clamped inside the mounting groove.

[0007] Furthermore, a connecting platform is fixedly installed at the bottom end of the engineering pile by bolts, and a pile head is rotatably connected to the bottom outer wall of the connecting platform, a connecting rod is integrally formed at the top of the pile head, and the top of the connecting rod passes through the top of the connecting platform, a hexagonal transmission sleeve is fixedly installed at the top of the connecting rod by bolts, and the hexagonal transmission sleeve is located inside the socket, a transmission shaft is inserted into the inside of the socket, and a hexagonal shaft is integrally formed at the bottom end of the transmission shaft, and the hexagonal shaft is clamped in the inside of the hexagonal transmission sleeve.

[0008] Furthermore, the lower part of the hexagonal transmission sleeve and the upper part of the pile head are both rotatably connected with axial bearings, and the outer walls of one side of the two axial bearings are in contact with the connecting platform.

[0009] Furthermore, a sealing ring is clamped on the bottom outer wall of the connecting platform, and the sealing ring is located between the bottom outer wall of the connecting platform and the top outer wall of the pile head.

[0010] Furthermore, a plurality of cutting blades are fixedly mounted on the side outer wall of the pile head by bolts, and the cutting blades are located below the connecting platform.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The engineering piles are cylindrical in structure. When they are driven into the soil layer, the surface force is relatively uniform, which can effectively prevent the engineering piles from deflecting. The resistance of the soil is small, and there are several longitudinal grooves on the surface of the engineering piles. The longitudinal grooves can reduce the volume of the engineering piles, greatly reduce the impact of soil squeezing, and can increase its surface area, making the engineering piles more stable.

[0013] 2. A pile head is provided with a plurality of cutting blades installed on the surface of the pile head. When the engineering pile is driven into the soil, the cutting blades on the pile head cut and squeeze the soil at the front end of the engineering pile to reduce the resistance of the soil, making it easier for the engineering pile to be driven into the soil. The relatively high-cost cutting blades are fixed to the pile head by bolts. If the cutting blades collide and collapse during transportation and hoisting, the collapsed cutting blades can be replaced separately without causing the pile head to be scrapped as a whole, thereby reducing the cost of use.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1: Please refer to Figures 1 to 3 The utility model provides a technical solution: a construction engineering pile, including a cap 1, a plurality of engineering piles 2 are fixedly installed on the bottom outer wall of the cap 1 by bolts, and a plurality of longitudinal grooves 8 are opened on the side outer wall of the engineering pile 2, a hanging plate 5 is fixedly installed on the top of the engineering pile 2 by bolts, and a positioning groove 17 is opened on the top outer wall of the hanging plate 5, a through hole 7 is opened on the bottom inner wall of the positioning groove 17, a plug hole 19 is opened on the top of the longitudinal groove 8, and the plug hole 19 and the through hole 7 are interconnected, and a plurality of lifting ears 6 are fixedly installed on the top outer wall of the hanging plate 5 by bolts.

[0020] From the above description, it can be seen that the utility model has the following beneficial effects: by setting up the engineering pile 2, the engineering pile 2 has a cylindrical structure. When it is driven into the soil layer, the surface force is relatively uniform, which can effectively prevent the engineering pile 2 from deflecting, and the resistance it receives from the soil is small. In addition, a plurality of longitudinal grooves 8 are opened on the surface of the engineering pile 2. The longitudinal grooves 8 can reduce the volume of the engineering pile 2, greatly reduce the impact of soil squeezing, and can increase its surface area, making the engineering pile 2 more stable.

[0021] For further information, see Figure 1 A mounting groove 3 is formed at the top of the cap 1 for connecting and fixing the engineering pile 2, and a cover plate 4 is clamped inside the mounting groove 3 for protecting the bolt structure inside the mounting groove 3.

[0022] Example 2: Please refer to Figures 1 to 3 As shown, on the basis of Example 1, the utility model provides a technical solution: a connecting platform 9 is fixedly installed at the bottom end of the engineering pile 2 by bolts, and a pile head 10 is rotatably connected to the bottom outer wall of the connecting platform 9, a connecting rod 14 is integrally formed at the top of the pile head 10, and the top of the connecting rod 14 passes through the top of the connecting platform 9, a hexagonal transmission sleeve 15 is fixedly installed at the top of the connecting rod 14 by bolts, and the hexagonal transmission sleeve 15 is located inside the insertion hole 19, a transmission shaft 12 is inserted into the inside of the insertion hole 19, and a hexagonal shaft 13 is integrally formed at the bottom of the transmission shaft 12, and the hexagonal shaft 13 is clamped in the inside of the hexagonal transmission sleeve 15 for transmitting torque, and an axial bearing 18 is rotatably connected to the bottom of the hexagonal transmission sleeve 15 and the top of the pile head 10, which can reduce friction, and one side outer walls of the two axial bearings 18 are in contact with the connecting platform 9.

[0023] By adopting the above technical scheme, a pile head 10 is set, and a plurality of cutting blades 11 are installed on the surface of the pile head 10. When the engineering pile 2 is driven into the soil, the cutting blades 11 on the pile head 10 cut and squeeze the soil at the front end of the engineering pile 2 to reduce the resistance of the soil, making it easier for the engineering pile 2 to be driven into the soil. The relatively expensive cutting blades 11 are fixed to the pile head 10 by bolts. If the cutting blades 11 collide and collapse during transportation and lifting, the collapsed cutting blades 11 can be replaced separately without causing the pile head 10 to be scrapped as a whole, thereby reducing the cost of use.

[0024] For further information, see Figure 3 A sealing ring 16 is clamped on the bottom outer wall of the connecting platform 9, and the sealing ring 16 is located between the bottom outer wall of the connecting platform 9 and the top outer wall of the pile head 10. A plurality of cutting blades 11 are fixedly installed on the side outer wall of the pile head 10 by bolts, and the cutting blades 11 are located below the connecting platform 9.

[0025] The working principle and use process of the utility model are as follows: when in use, the operator first fixes the hanging plate 5 to the top of the engineering pile 2 by bolts, and then can lift the engineering pile 2 by using the lifting lug 6 through a crane, etc., then the operator inserts the transmission shaft 12 into the interior of the engineering pile 2, and makes the hexagonal shaft 13 at one end of the transmission shaft 12 clamped in the interior of the hexagonal transmission sleeve 15, and then installs it on the pile driving system, and the motor of the pile driving system drives the transmission shaft 12 to rotate, and the transmission shaft 12 drives the hexagonal transmission sleeve 15 and the connecting rod 14. The movable pile head 10 rotates, so that the pile head 10 and the cutting blade 11 on the pile head 10 cut and squeeze the soil, and the pressure output end of the pile driving system presses the engineering pile 2 downward through the positioning groove 17, so that the engineering pile 2 can be driven into the soil. After the engineering pile 2 is completely driven into the soil, the operator removes the hanging plate 5 and the transmission shaft 12, and then fixes the base 1 to the top of multiple engineering piles 2 with bolts, and finally clamps the cover plate 4 into the inside of the installation groove 3, so that construction can be carried out on the top of the base 1.
