Abstract
Description
Technical Field
[0001] The present application relates to the technical field of precast piles, and in particular to a verticality detection precast pile and a construction method thereof. Background Art
[0002] In building foundation engineering, construction units use piles of various structures to reinforce the foundation, among which precast piles are widely used in the field of building pile foundations due to their good economic and technical indicators. Precast piles are manufactured in advance in the factory, so they can be designed and manufactured in different structures according to functional needs, with strong functionality, and have the advantages of simple on-site construction, small deformation, and stable quality.
[0003] The conventional construction method of precast piles includes the following steps: determining the position and depth of the pile hole, opening the pile hole, cleaning the mud and stone in the pile hole, sinking the pile, connecting the piles, pouring concrete, and treating the precast pile head.
[0004] With regard to the above-mentioned related technologies, in order for the precast pile to enter the underground, the size of the pile hole is slightly larger than the precast pile, so the precast pile has space for a small swing. After pouring concrete between the pile hole and the precast pile, if the stress generated by the concrete at different positions is different, the precast pile will also be pulled to tilt slightly. The existing means cannot perform simple and effective real-time detection of the inclination of the precast pile. If the detection is too late and the concrete has solidified, the precast pile cannot be corrected, resulting in the problem of excessive verticality error. Summary of the invention

Therefore, the C-shaped opening position of the conductive strip 1 is the tilting direction of the pile body. This structure makes it easy to determine the tilting direction of the pile body.

[0016] Optionally, a plurality of steel rings are fixed in the pile body along its length direction, and the steel rings are connected to the steel bars by arranging insulating blocks.

DETAILED DESCRIPTION
[0029] The present application is further described in detail below in conjunction with the accompanying drawings.
[0030] Embodiment 1:
[0031] Reference Figure 1 and Figure 2 This embodiment discloses a prefabricated pile for verticality detection, including a pile body 1. The pile body 1 is cylindrical. A central hole 11 is provided inside the pile body 1. The central hole 11 is arranged concentrically with the pile body 1. The central hole 11 penetrates the pile body 1 upward, but does not penetrate downward. A top rod 12 is fixed to the top of the pile body 1. The top rod 12 is arranged horizontally. Both ends of the top rod 12 are inserted into the two sides of the hole wall of the central hole 11. A metal wire 2 is fixed to the top rod 12. A metal block 21 is fixed to the lower end of the metal wire 2. The metal block 21 is located in the central hole 11. The metal wire 2 is located on the central axis of the pile body 1. The outer peripheral wall of the metal block 21 is circular. The metal block 21 is located in the middle or lower middle part of the pile body 1. If the pile body 1 is in a vertical state, under the action of gravity, the central axis of the metal block 21 coincides with the central axis of the pile body 1 and the central hole 11.
[0032] Reference Figure 3 and Figure 4 A plurality of steel bars 3 are fixed in the circumferential direction of the pile body 1. The length direction of the steel bars 3 extends along the length direction of the pile body 1. The upper end of the steel bars 3 passes through the outside of the pile body 1, and the lower end of the steel bars 3 does not pass through the pile body 1. A plurality of steel rings 31 are fixed in the pile body 1 along its length direction. The steel rings 31 and the steel bars 3 are connected by setting an insulating block 32. The surface of the insulating block 32 is provided with a limiting groove 33 for the steel rings 31 and the steel bars 3 to be clamped. The limiting groove 33 is a shrinking groove. The insulating block 32 can be made of plastic. The limiting groove 33 facilitates the assembly of the insulating block 32 with the steel rings 31 and the steel bars 3, thereby improving the efficiency of factory production. At the same time, the insulating block 32 prevents the adjacent steel bars 3 from conducting electricity. The plurality of steel rings 31 and the steel bars 3 are combined by the insulating block 32 to form a steel cage as the skeleton support structure of the pile body 1.
[0033] Reference Figure 3 and Figure 5 The steel bar 3 is fixed with a metal rod 34, the height position of the metal rod 34 is located at the metal block 21, the metal rod 34 penetrates into the middle hole 11, and the end of the metal rod 34 located in the middle hole 11 is forked into two support rods, which extend along the circumference of the metal block 21. All the metal rods 34 surround the metal block 21, and the ends of the metal rods 34 are arranged close to the metal block 21. There is a distance between different metal rods 34 to avoid contact.
[0034] Reference Figure 2 The upper end of the pile body 1 is provided with a conductive strip 4, which is provided in contact with a plurality of reinforcing bars 3. The conductive strip 4 is made of a thin-walled metal conductor, such as aluminum or copper. The conductive strip 4 is in sliding contact with a plurality of reinforcing bars 3. The conductive strip 4 is C-shaped, and a corresponding reinforcing bar 3 is provided at the C-shaped opening of the conductive strip 4. A chute 41 for the reinforcing bar 3 to enter is provided at the bottom of the conductive strip 4. The conductive strip 4 clamps the reinforcing bar 3 through the groove wall of the chute 41. The thin-walled conductive strip 4 can be deformed, and the reinforcing bar 3 enters the chute 41 by expanding the chute 41. Therefore, there is a clamping force between the conductive strip 4 and the reinforcing bar 3 to ensure conductivity.
[0035] A conductive bar 2 42 is installed at the C-shaped opening of the conductive bar 1 4. The cross-sectional shape of the conductive bar 2 42 is the same as that of the conductive bar 1 4. The conductive bar 2 42 is arranged in contact with the corresponding steel bar 3. The two ends of the conductive bar 2 42 are in contact with the two ends of the conductive bar 1 4. The conductive bar 1 4 and the conductive bar 2 42 are combined into a complete ring.
[0036] The implementation principle of a verticality detection prefabricated pile in an embodiment of the present application is as follows: the metal wire 2 and the conductive strip 4 are respectively used to connect the two ends of the circuit. When the pile body 1 is in a vertical state, the metal block 21 does not contact any metal rod 34, so the current cannot be conducted; if the pile body 1 is tilted, the longer metal wire 2 amplifies the relative displacement of the metal block 21 when the pile body 1 is tilted, and the metal block 21 is displaced a sufficient distance to the tilted side of the pile body 1, and the metal block 21 touches the metal rod 34. Then, the metal wire 2, the metal block 21, the metal rod 34, the steel bar 3, and the conductive strip 4 connect the circuit in sequence, so that it is possible to judge whether the inclination of the pile body 1 meets the requirements by the on-off current, and real-time detection can be performed.
[0037] Embodiment 2:
[0038] A construction method for a verticality detection prefabricated pile, using a verticality detection prefabricated pile of the first embodiment, comprises the following steps: Step S1: Remove the conductive bar 1 4 and the conductive bar 2 42, and install the pile body 1 into the pile hole; avoid damaging the conductive bar 1 4 and the conductive bar 2 42 during the pile placement process.
[0039] Step S2: Refer to Figure 6 Conductive strip 1 4 and conductive strip 2 42 are installed on the upper end of the pile body 1, and conductive strip 1 4 and conductive strip 2 42 are combined into a ring-shaped conductor. Take power supply 5, alarm 51, and wire 52, and use wire 52 to connect metal wire 2, power supply 5, alarm 51, and conductive strip 1 4 in sequence; power supply 5 can be a battery or an adapter connected to the mains, and alarm 51 is a buzzer and / or a warning light. The type of alarm 51 is selected according to the needs of the site, and it can make a sound or light, or make a sound and light at the same time to remind. The end of the wire 52 is electrically connected with a metal clip 53, and the wire 52 is electrically connected to the metal wire 2 and conductive strip 1 4 through the metal clip 53. The metal clip 53 facilitates the connection of the two ends of the wire 52, which is convenient to use.
[0040] Step S3: If the alarm 51 sounds an alarm, it means that the inclination of the pile body 1 exceeds the threshold value, and the metal block 21 is in contact with the metal rod 34. Remove the conductive bar 2 42, slide the conductive bar 1 4, until the alarm 51 stops working, which means that the steel bar 3 that is not in contact with the conductive bar 1 4 is electrically connected to the metal block 21. Therefore, the C-shaped opening position of the conductive bar 1 4 is the inclination direction of the pile body 1, and it is corrected by pulling the upper end of the pile body 1; after completion, reinstall the conductive bar 2 42.
[0041] It should be noted that before and after correction, the contact between the metal block 21 and each metal rod 34 can be observed from the top of the pile body 1 by using a flashlight to improve efficiency.
[0042] Step S4: pouring concrete between the outer wall of the pile body 1 and the pile hole.
[0043] Step S5: Repeat the above step S3 until the concrete solidifies. During the solidification process of the concrete, if the stress generated by the concrete at different positions is different, the pile body 1 will be pulled to slightly tilt. The above method is used for detection. After the tilt is detected, the alarm 51 immediately issues an alarm to remind the construction personnel, so that the pile body 1 can be slightly corrected before the concrete is completely solidified.
[0044] After the above construction is completed, concrete can be poured into the middle hole 11 to avoid the pile body 1 from being hollow and to improve the overall strength of the pile body 1 .
[0045] In summary, through the verticality detection prefabricated pile and its construction method, the inclination of the pile body 1 can be simply and effectively detected in real time, and the items forming the circuit are also easy to obtain, basically available at the construction site, and the cost is low. Through the prefabricated pile and its construction method, the problem of the prefabricated pile being unable to correct due to the detection being too late and the concrete being solidified is avoided, and the problem of the prefabricated pile having too large verticality error is avoided.
[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
