Abstract
Description
Technical Field
[0001] The utility model belongs to core piles, and particularly relates to a stiff composite pile core pile. Background Art
[0002] A stiff composite pile is a composite carrier, that is, a cement-soil mixing pile is combined with a prestressed pipe pile to improve its compressive strength. Among them, the cement-soil mixing pile uses cement as a curing agent, and admixtures such as fly ash with an indefinite doping ratio are incorporated. The soft soil and cement are forcibly stirred by a mixer to form cement soil. After the mixing pile is formed, a prestressed pipe pile is inserted. After the cement soil hardens, it tightly wraps the precast pile body, thus forming a new pile body with higher strength. Therefore, the perpendicularity of the prestressed pipe pile is crucial for the bearing performance of the stiff composite pile.
[0003] During the construction process of the existing stiff composite piles, the inclination of the pile body cannot be monitored in real time. When the pile body is inclined, an alarm cannot be issued in time, resulting in difficulty for construction workers to discover and handle the inclination problem in time, increasing the construction risk. Moreover, after the existing stiff composite piles are inclined, there are no effective deviation correction means, or the deviation correction process is complex and difficult to accurately control, resulting in the perpendicularity of the pile body being difficult to meet the design requirements and affecting the overall project quality. Summary of the Utility Model
[0004] Object of the Invention: In order to overcome the deficiencies existing in the prior art, the object of the present utility model is to provide a stiff composite pile core pile with inclinometer and deviation correction functions.
[0005] Technical Solution: A stiff composite pile core pile according to the present utility model includes a prestressed pipe pile, a deviation correction mechanism, and an inclinometer mechanism. The prestressed pipe pile is of a hollow structure. The deviation correction mechanism and the inclinometer mechanism are both arranged inside the prestressed pipe pile. The deviation correction mechanism and the inclinometer mechanism are electrically connected. The deviation correction mechanism includes a deviation correction tension bar, a positioning hole, and an anchor plate. The positioning hole penetrates through the prestressed pipe pile. The deviation correction tension bar is arranged inside the positioning hole, and the deviation correction tension bar is connected to the anchor plate.
[0006] Further, the length of the deviation correction tension bar is greater than the length of the prestressed pipe pile, and the deviation correction tension bar extends outside the prestressed pipe pile.
[0007] Further, the deviation correction tension bar is welded to the anchor plate.
[0008] Further, the inclinometer mechanism includes a buzzer, a pull rope, a heavy ball, a piezoelectric layer, an inclinometer hole, and a wire. The buzzer is located outside the prestressed pipe pile. The inclinometer hole is opened at the top of the prestressed pipe pile. The pull rope, the heavy ball, the piezoelectric layer, and the wire are all located inside the inclinometer hole.
[0009] Further, the heavy ball is connected to the buzzer through a pulling rope and a wire, and the piezoelectric layer is arranged on the outer side of the heavy ball. The depth of the inclinometer hole is not less than 10 cm. The length of the wire is greater than twice the length of the pulling rope. The heavy ball is an insulating heavy ball. The diameter of the heavy ball is smaller than the inner diameter of the inclinometer hole.
[0010] Further, the positioning holes are uniformly distributed on the prestressed pipe pile in a circumferential array.
[0011] Working principle: When the inclination angle of the rigid composite pile core pile is greater than the designed value, the heavy ball inclines under the action of gravity and collides with the side wall of the inclinometer hole. At this time, the piezoelectric layer generates a voltage, and the working circuit of the buzzer forms a path, and the buzzer starts to work. Through the alarm of the buzzer, the construction personnel can timely understand the inclination of the pile body and take corresponding deviation correction measures. According to the actual inclination direction, pull out the necessary tensioned reinforcement for deviation correction, and continuously adjust the verticality of the core pile. When the buzzer does not work, it means that the verticality of the core pile meets the design requirements at this time. After the construction of the core pile is completed, inject cement mortar into the positioning hole to improve the overall structural integrity and strength of the rigid composite pile core pile, and at the same time remove the inclinometer structure for the inclinometer measurement of the next rigid composite pile core pile.
[0012] Beneficial effects: Compared with the prior art, the utility model has the following characteristics:
[0013] 1. The inclinometer mechanism can real-time monitor the inclination of the pile body during the construction process. When the inclination exceeds the design requirements, the buzzer will timely give an alarm to remind the construction personnel to take corresponding measures. The deviation correction mechanism can accurately adjust the verticality of the prestressed pipe pile by pulling out the tensioned reinforcement for deviation correction, ensuring that the pile body maintains a stable posture during the construction process and meets the design requirements;
[0014] 2. The tensioned reinforcement for deviation correction is retained in the positioning hole after the construction is completed and cement mortar is injected, which not only realizes the reliable connection of the upper and lower sections of the prestressed pipe pile, but also can improve the overall structural integrity and strength.

[0020] As Figures 1 to 3 , the interior of the prestressed pipe pile 1 of the stiffened composite pile core pile is a hollow structure, and the deviation correction mechanism 2 and the inclinometer mechanism 3 are both arranged inside the prestressed pipe pile 1. The deviation correction mechanism 2 includes deviation correction tension bars 21, positioning holes 22 and anchor plates 23. A plurality of positioning holes 22 are uniformly distributed in a circumferential array at the end of the prestressed pipe pile 1, and the positioning holes 22 completely penetrate the prestressed pipe pile 1. The deviation correction tension bars 21 are arranged inside the positioning holes 22, and one end of the deviation correction tension bars 21 is connected to the anchor plate 23. The length of the deviation correction tension bars 21 is greater than the length of the prestressed pipe pile 1, and one end of it extends outside the prestressed pipe pile 1. The anchor plate 23 is located at the bottom of the prestressed pipe pile 1, and the number and positions of the deviation correction tension bars 21, the positioning holes 22 and the anchor plate 23 correspond to each other. One inclinometer hole 35 is opened on the prestressed pipe pile 1 to realize the real-time monitoring of the inclination. The length of the inclinometer hole 35 is short, and it is only opened in a local range at the upper part of the prestressed pipe pile 1 body. It is recommended that the length is not less than 10 cm.
[0021] The prestressed pipe pile 1, as the core pile of the stiffened composite pile, is the main load-bearing component. By combining with the cement-soil mixing pile, it forms a new pile body with high strength, providing a certain bearing capacity and compressive strength. The deviation correction mechanism 2 can accurately adjust the inclination of the pile body to ensure the verticality and stability of the pile body. The deviation correction tension bars 21 are used to adjust the verticality of the prestressed pipe pile 1 to ensure the stability of the pile body during construction. By pulling the deviation correction tension bars 21, the inclination of the pile body can be effectively adjusted to meet the design requirements. The positioning holes 22 provide an installation position for the deviation correction tension bars 21 to ensure that they can be accurately fixed on the prestressed pipe pile 1. When the deviation correction work is completed, cement mortar can be injected into the positioning holes 22. The anchor plate 23 fixes one end of the deviation correction tension bars 21 at the bottom of the prestressed pipe pile 1 to ensure the stability during the deviation correction process. The design of the anchor plate 23 enhances the connection strength between the deviation correction tension bars 21 and the prestressed pipe pile 1 and improves the deviation correction effect.
[0022] As Figures 4 to 5, the inclinometer mechanism 3 includes a buzzer 31, a pull rope 32, a weight ball 33, a piezoelectric layer 34, an inclinometer hole 35, and a wire 36. The piezoelectric layer 34 is a power load and forms a circuit in series with the buzzer 31 through the wire 36. The buzzer 31 is located outside the prestressed pipe pile 1. The inclinometer hole 35 is opened at the top of the prestressed pipe pile 1. The pull rope 32, the weight ball 33, the piezoelectric layer 34, and the wire 36 are all located inside the inclinometer hole 35. The weight ball 33 is connected to the buzzer 31 through the pull rope 32 and the wire 36. The piezoelectric layer 34 is arranged on the outside of the weight ball 33. When the piezoelectric layer 34 is subjected to an external pressure, a voltage will appear at both ends. The diameter of the inclinometer hole 35 is larger than the diameter of the weight ball 33. The actual diameter of the inclinometer hole 35 should be determined according to the length and inclination requirements of the prestressed pipe pile 1. For a pile body length with an inclination ≤ 1%, the depth of the inclinometer hole 35 is not less than 10 cm. The weight ball 33 is made of an insulating material, and the diameter of the weight ball 33 is smaller than the inner diameter of the inclinometer hole 35. The weight ball 33 serves as a gravity sensing element of the inclinometer structure. When the pile body inclines, it tilts and collides with the side wall of the inclinometer hole 35. The tilt and collision of the weight ball 33 trigger the generation of voltage in the piezoelectric layer 34. At this time, there is current passing through the circuit, and the buzzer 31 works, thus realizing the real-time monitoring of the inclination. The pull rope 32 is preferably made of a material that does not produce elastic deformation. At the same time, it can tilt under the pulling action of the weight ball 33 to ensure that the signal can be accurately transmitted when the weight ball 33 tilts. The wire 36 should always be in a relaxed state. It is recommended that the length is not less than twice the length of the pull rope 32. The wire 36 is defaulted to be not subjected to other external forces except gravity during the construction process of the entire stiffened composite pile.
[0023] The inclinometer mechanism 3 can monitor the inclination of the pile body in real time. When the inclination angle of the core pile of the stiffened composite pile is greater than the design value, the weight ball 33 tilts under the action of gravity and collides with the side wall of the inclinometer hole 35. At this time, the piezoelectric layer 34 generates a voltage, and the working circuit of the buzzer 31 forms a path, and the buzzer 31 starts to work. Through the alarm of the buzzer 31, the construction personnel can timely understand the inclination of the pile body and take corresponding deviation correction measures. According to the actual inclination direction, pull out the necessary tensioned reinforcement bars 21 for deviation correction, and continuously adjust the verticality of the prestressed pipe pile 1. One end of the tensioned reinforcement bar 21 for deviation correction is fixed at the bottom of the prestressed pipe pile 1 through an anchor plate 23, and the other end extends out of the pile top. The inclination of the pile body can be accurately adjusted through the pulling operation. When the buzzer 31 does not work, it means that the verticality of the core pile meets the design requirements at this time. After the construction of the core pile is completed, inject cement mortar into the positioning hole 22 to improve the overall structural performance and strength of the core pile of the stiffened composite pile. At the same time, take out the inclinometer structure 3 for the inclinometer work of the next core pile of the stiffened composite pile.
