[0002] The pile head of a cast-in-place concrete pile refers to the partial structure at the top of the pile body, also called the pile cap or pile top. The main function of the pile head is to bear and transfer the upper load to the pile body, and to ensure a firm and reliable connection between the pile body and the superstructure. The pile head of a cast-in-place concrete pile is usually cast by concrete. The pile head needs to be connected to the superstructure. Common connection methods include steel bar welding, bolt connection, etc. The choice of connection method should take into account the interaction and mechanical properties between the pile body and the superstructure to ensure a firm and reliable connection.

[0052] The utility model provides a concrete cast-in-place pile head steel bar anti-corrosion structure, which comprises a pile body 1, pile longitudinal bars, stirrups 3 and a conductive component 4; the pile body 1 is a vertical cylindrical structure, and the pile body is pre-buried in the ground; the pile longitudinal bars are vertically arranged, and the pile longitudinal bars are arranged in a plurality of groups, and the plurality of groups of pile longitudinal bars are arranged around the inner circumference of the pile body template, and the pile longitudinal bars comprise a pile head body 2 extending from the top of the pile body, and at least two pile head bodies 2 are provided with threaded external threads on the top; the stirrups 3 are located above the pile body template, and the stirrups are sleeved on the outer rings of the plurality of pile head bodies 2, and the stirrups 3 are connected to the pile head bodies 2 by iron wire binding; the conductive component 4 is threadedly connected with the threaded external threads, and the conductive component is used to transmit electricity to the pile longitudinal bars, and the conductive component comprises an anode connection group and a cathode connection group, and at least two pile head bodies 2 are respectively connected with the anode connection group and the cathode connection group, and the outer sides of the anode connection group and the cathode connection group are both plugged with a connection component 5, and the connection component 5 is used for an external circuit.

[0053] In this embodiment, a plurality of pile longitudinal bars are arranged on the top surface of the pile body 1 and near the circumferential position, stirrups 3 are sleeved on the top of the pile body 1 and located on the outside of the pile longitudinal bars, and the stirrups 3 are connected to each pile longitudinal bar by wire binding, wherein two symmetrical pile longitudinal bars are threaded with external threads near the top position, wherein the two pile longitudinal bars with external threads are threadedly connected with conductive components 4, the conductive components 4 are used to transmit electricity to the pile longitudinal bars, and a power connection component 5 is plugged into the outside of each conductive component 4, the power connection component 5 is used for an external circuit, and the potential of the conductive component 4 is lower than the potential of the pile longitudinal bars.

[0054] The multiple pile longitudinal bars on the pile body 1 can provide an attachment foundation for the stirrups 3 and can also be connected by wire tying, thereby improving the stability of the connection between the two.

Then, the two power connection components 5 are respectively plugged and installed on the outside of the conductive component 4, so that the two can be tightly connected together, and then the two power connection components 5 are respectively connected to the positive and negative poles of the external power supply. Since the potential of the conductive component 4 is lower than the potential of the pile longitudinal reinforcement, the metal of the low-potential conductive component 4 will release electrons and undergo an oxidation reaction, thereby protecting the high-potential pile longitudinal reinforcement from corrosion.

Since the potential of the hexagonal nut 41 is lower than the potential of the pile longitudinal reinforcement, the low-potential metal of the hexagonal nut 41 can release electrons, undergo an oxidation reaction, and protect the high-potential pile longitudinal reinforcement from corrosion.

[0070] The working principle of this utility model:

[0071] The plurality of pile longitudinal bars on the pile body 1 can provide an attachment foundation for the stirrups 3 and can also be connected by iron wire binding, thereby improving the stability of the connection between the two. The two symmetrical pile longitudinal bars are threaded with external threads near the top, and the two pile longitudinal bars with external threads are threaded with conductive components 4, and each conductive component 4 is plugged with a power connection component 5 on its outer side.

[0072] 1. When each pile longitudinal reinforcement needs to be treated for corrosion, the staff first installs two conductive components 4 on the pile head bodies 2 of the two pile longitudinal reinforcements with external threads, and tightens and fixes the conductive components 4.

[0073] 2. Then, the two power connection components 5 are respectively plugged and installed on the outside of the conductive component 4, so that the two can be tightly connected together.

[0074] 3. Connect the two power connection components 5 to the positive and negative poles of the power source respectively. Since the potential of the conductive component 4 is lower than the potential of the pile longitudinal reinforcement, the metal of the low-potential conductive component 4 will release electrons and undergo an oxidation reaction, thus protecting the high-potential pile longitudinal reinforcement from corrosion.

[0075] The conductive component 4 is the anode, the pile longitudinal reinforcement is the cathode, and the circular stirrup 3 is the conductor. The specific reaction formula is as follows:

[0076] Anode: M-ne - =M n+

[0077] Cathode: nO2 / 4+ne - +nH2O / 2=nOH -

[0078] Overall reaction formula: M+nO2 / 4+nH2O / 2=M n+ +nOH -

[0079] Among them, M represents low-potential metal (selected by design), n represents quantity, and e- represents electrons.

[0080] This design improves the corrosion resistance of each pile longitudinal reinforcement, and by binding the stirrups 3 with each pile longitudinal reinforcement with iron wire, it can ensure good electrical connectivity, which is convenient for the subsequent pile body concrete pouring construction.

[0081] The concrete cast-in-place pile head steel bar anti-corrosion structure of the utility model can be threadedly installed on the pile longitudinal bar with external thread through the hexagonal nut 41 in the conductive component 4, and corresponding convex grooves 42 can be opened in the middle of the three adjacent side walls, and then one end of the connecting component 5 can be plugged and connected through the three convex grooves 42, which can facilitate the connection and conduction of electrical energy between the two, and also facilitate the disassembly and separation of the two, so that the hexagonal nut 41 can be disassembled. Since the potential of the hexagonal nut 41 is lower than the potential of the pile longitudinal bar, the metal of the low-potential hexagonal nut 41 can release electrons, undergo oxidation reaction, and protect the high-potential pile longitudinal bar from corrosion.

[0082] Through the second connection part 512 in the power connection component 5, a stable foundation can be provided for the three first connection parts 511, and a foundation can be provided for the opening of the multiple first internal thread grooves 513.

Through the plurality of stepped holes 55, the fixing screws 56 can be threadedly installed on the first internal thread groove 513, so that the second clamping block 52 can be stably and firmly installed on the second connection part 512. Through the power connection board 53, the external cable can be connected through the wiring hole 54, so that the external power supply can be conveniently used to power the device.

[0083] The spring pin 515 in the second internal thread groove 514 can provide elastic support after the first connection part 511 is inserted into the convex groove 42, thereby improving the stability of the first connection part 511 inserted into the convex groove 42, and thus preventing the two from falling off. The stabilizing wing 516 can strengthen the connection strength between the first connection part 511 and the second connection part 512, thereby improving the stability of the use of the first connection part 511. The limiting pin 517 and the limiting hole 58 can further strengthen the stability of the connection between the second connection part 512 and the second clamping block 52, thereby preventing the power board 53 from being pulled and causing the second connection part 512 to separate from the second clamping block 52, thereby ensuring the stability of the connection between the two. The flame retardant plug 57 can not only block the stepped hole 55, but also prevent it from spontaneously igniting. The two reinforcing ribs 59 can strengthen the structural strength of the wiring hole 54 on the power board 53, thereby improving the service life of the power board 53.
