Description

Technical Field

[0001] The invention belongs to the technical field of pole root area reinforcement, and in particular relates to a pole root field forming reinforcement structure and a manufacturing method thereof. Background Art

[0002] The area where the pole root contacts the ground is usually prone to damage, ranging from 0.5 meters below the ground to 1.5 meters above the ground. When the damage is serious, the pole may fall over, seriously endangering the safe operation of the line. The main causes of damage include corrosive medium erosion, frost heave, external force collision and other factors. If the pole is upgraded as a whole to resist these destructive factors, it will inevitably cause a substantial increase in costs, which will be a waste for areas without risks of corrosive medium erosion, frost heave, external force collision, etc. Traditional reinforcement methods often use solutions such as pouring concrete piers or masonry stone piers, which not only increase the land area, but also affect the appearance. There is also a solution of using two semicircular steel structure clamps for reinforcement. Since the two halves are connected by bolts on the ear plate, not only is the strength low, but the corrosive medium will continue to invade the gap in the middle, and effective protection cannot be achieved. Summary of the invention

[0003] The purpose of the present invention is to provide a field-formed reinforcement structure for the root of an electric pole and a manufacturing method thereof, so as to accurately and effectively protect the destructive factors encountered at the root of the electric pole, while reducing costs without increasing floor space.

The group of longitudinal ribs, the group of annular ribs, and the group of steel bar limiting rings together form a steel cage of the high-performance reinforced concrete reinforcement structure at the pole root. One of the steel bar limiting rings is arranged at the lower end of the longitudinal rib, and the rest are arranged upward. The steel bar limiting rings match the diameter of the pole where they are located. Each steel bar limiting ring is a circular ring formed by two semicircular metal rings with connecting holes at both ends connected by a pin shaft, or each steel bar limiting ring is a circular ring with an opening.

[0005] The steel cage is cylindrical or truncated cone-shaped with the same taper as the reinforced electric pole.

[0006] The number of the group of longitudinal ribs is 6 to 20 and they are evenly distributed along the circumference.

[0007] The thread pitch at the beginning and end of the group of annular ribs is increased, and the thread pitch in the middle is 50mm-200mm.

[0008] The circular ring with openings is a structure with connecting holes at both ends, a connecting hole at one end and a pin at the other end, or a structure with straight sections at both ends.

[0009] The steel bar limiting ring is provided with a positioning ring or a positioning stop, and the number of the positioning rings or the positioning stop is consistent with the number of the longitudinal bars and is evenly distributed along the circumference.

[0010] The longitudinal ribs or the steel bar limiting rings are provided with outwardly protruding pads.

[0011] A spiral steel wire is wound around the single longitudinal reinforcement, and the spiral outer diameter of the spiral steel wire is smaller than the wall thickness of the high-performance reinforced concrete reinforcement structure.

[0012] The lower end of the high-performance reinforced concrete reinforcement structure is located between 0.3m and 1m below the ground, and the upper end extends to 0.6m to 2m above the ground.

[0013] A method for manufacturing a pole root on-site forming reinforcement structure, characterized by comprising the following steps: Step 1: Dig a circular foundation pit at the base of the pole according to the required depth for protection. When the foundation pit exceeds a certain depth, the pole needs to be supported to prevent it from falling. Step 2: Install and fix the longitudinal ribs: (1) The steps for installing the longitudinal reinforcement of the steel bar limiting ring with a positioning ring or a positioning stop on the steel bar limiting ring are: When the steel bar limiting ring is two semicircular metal rings with connecting holes at both ends, the two semicircular metal rings of each steel bar limiting ring are surrounded on the outer surface of the pole and connected by pins or longitudinal bars are used instead of pins to penetrate the connecting holes to form a circular steel bar limiting ring. When the steel bar limiting ring is a circular ring with an opening, the opening of the steel bar limiting ring is opened, put on the electric pole, and then the opening is closed; When the steel bar limiting ring is a circular ring with an opening, and the circular ring with an opening has a connection hole at one end and a pin at the other end, the pin at one end is inserted into the connection hole at the other end for connection; when the circular ring with an opening has connection holes at both ends, the pin is inserted into the connection hole or a longitudinal rib is used to replace the pin to insert into the connection hole to form a circular steel bar limiting ring; When the steel bar limiting ring is a circular ring with an opening and both ends of the circular ring with an opening are straight sections, a temporary pad is installed between the steel bar limiting ring and the electric pole; Pull the steel bar limit rings apart and fix them at a set distance, insert the longitudinal bars into the positioning rings or place them against the positioning blocks, and further tie and fix them if necessary; When a spiral steel wire is provided on a single longitudinal reinforcement, the spiral steel wire must be pulled to a set length first. If there is a positioning ring on the reinforcement limit ring, the spiral steel wire and the positioning ring are placed coaxially, and the longitudinal reinforcement is inserted into the spiral steel wire and the positioning ring at the same time; If there is a positioning stop on the steel bar limiting ring, first insert the longitudinal reinforcement into the spiral steel wire, and then place the longitudinal reinforcement 1 against the positioning stop; Form a uniformly arranged longitudinal reinforcement structure supported and positioned by a circular reinforcement limiting ring; (2) The installation steps for the steel bar limit ring without a positioning ring or positioning stop and the longitudinal reinforcement needs to be tied or welded are: When a single longitudinal reinforcement is provided with a spiral steel wire, the spiral steel wire must be pulled to a set length first, the longitudinal reinforcement must be inserted into the spiral steel wire, and then the following operations are performed in the same manner as the longitudinal reinforcement without a spiral steel wire: when the reinforcement limiting ring is two semicircular metal rings with connecting holes at both ends, the semicircular metal rings of each required reinforcement limiting ring are placed and fixed at the set positions of the reinforcement limiting rings to form a group of semicircular metal rings, and half of the longitudinal reinforcements are tied or welded to this group of semicircular metal rings at the set positions, and every two semicircular structures including a group of semicircular metal rings and half of the longitudinal reinforcements are placed opposite to each other to form a truncated cone or cylindrical structure, and the two semicircular structures are wrapped on the outer surface of the pole, and each pair of semicircular metal rings are connected with a pin shaft, and when the reinforcement limiting rings have connecting holes at both ends or longitudinal reinforcements are used instead of pin shafts to penetrate the connecting holes for connection, a uniformly arranged structure of longitudinal reinforcements supported and positioned by circular reinforcement limiting rings is formed; When the steel bar limiting ring is a circular ring with an opening, each required steel bar limiting ring is placed and fixed at a set position to form a group of steel bar limiting rings, the required longitudinal reinforcement is tied or welded to the group of steel bar limiting rings at a set position, all openings of a group of steel bar limiting rings with longitudinal reinforcement are opened, put on the pole, and then the openings are closed; When the steel bar limiting ring is a circular ring with an opening and one end of the circular ring with an opening has a connection hole and the other end has a pin shaft, the pin shaft at one end is inserted into the connection hole at the other end for connection; when the circular ring with an opening has connection holes at both ends, the pin shaft is inserted into the connection holes or longitudinal ribs are used to replace the pin shafts and inserted into the connection holes for connection to form a longitudinal rib uniformly arranged structure supported and positioned by the circular steel bar limiting ring; When the steel bar limiting ring is a circular ring with an opening and the two ends of the circular ring with an opening are straight sections, a temporary pad must be installed between the steel bar limiting ring and the pole when the two ends of the steel bar limiting ring are closed to prevent the steel bar limiting ring hoop from being tightly attached to the pole when the annular reinforcement is subsequently wound, so that the steel bar cage cannot be moved downward; Step 3: Circumferential reinforcement winding; The evenly arranged structure of the longitudinal reinforcement is lifted so that the steel bar limiting ring at the lower end is located above the ground and supported, and the annular reinforcement is spirally wound from bottom to top or from top to bottom to the surface of the longitudinal reinforcement in the form of dense ends and uniform pitch in the middle to form a complete steel cage. After the annular reinforcement is wound, when the steel bar limiting ring is a circular ring with an opening and the two ends of the circular ring with an opening are straight sections, the temporary pad installed between the steel bar limiting ring and the pole is removed, so that there is a certain gap between the steel bar limiting ring and the pole, which is convenient for the steel cage to move downward; Step 4: Install the shape forming mold: Install a protruding pad on the longitudinal rib or the steel bar limiting ring to limit the distance between the shape forming mold and the steel bar. When the spiral outer diameter of the spiral steel wire is close to the wall thickness of the high-performance reinforced concrete structure, the protruding pad is not installed. Remove the support at the bottom of the steel bar limiting ring, sink the steel cage to the bottom of the foundation pit, and install the shape forming mold on the surface of the steel cage; the step of installing the mold may be placed before the steel cage sinks to the bottom of the foundation pit. When the steel cage sinks, the mold sinks to the bottom of the foundation pit together with the steel cage;

[0014] Step 5: High-performance concrete mortar molding; pour high-performance concrete mortar into the gap between the top of the mold and the pole until the gap is completely filled, let it stand and cure until the high-performance concrete mortar hardens, then remove the mold, trim the edges, and check to confirm that it meets the standards before completing all the work. If the mold is a disposable mold made of corrosion-resistant thin plates, the high-performance concrete mortar will not be removed after hardening.

[0015] Advantages of the present invention: The on-site formed reinforcement structure for the root of the electric pole of the present invention and the manufacturing method thereof can reinforce the parts of the electric poles installed in the areas with risk of damage, realize precise protection, control the cost and achieve the protection effect; this scheme is not only suitable for the reinforcement of the electric poles in operation, but also suitable for the repair of the damaged electric poles, and can not only repair the above-ground part, but also repair the underground part at the same time, completely eliminating the safety hazards of the electric poles; compared with other repair schemes, the scheme provided by the present invention has more reliable reinforcement effect, simple installation, easy use and convenient construction.

Implementation

[0027] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings.

[0028] like Figure 1-10 As shown, the pole root field-formed reinforcement structure of the present invention is characterized in that it includes a layer of high-performance reinforced concrete reinforcement structure wrapped around the outer surface of the root area of ​​the upright installed pole 11, the high-performance reinforced concrete reinforcement structure includes a group of longitudinal ribs 1 evenly distributed along the circumference, a group of steel bar limiting rings 3 arranged on the inner side of the group of longitudinal ribs 1, a group of annular ribs 2 spirally wound around the outer surface of the group of longitudinal ribs 1, and a high-performance concrete mortar 6 covering the outermost layer. The group of longitudinal ribs 1, the group of annular ribs 2, and the group of steel bar limiting rings 3 together form a steel cage of the high-performance reinforced concrete reinforcement structure at the pole root. One of the steel bar limiting rings 3 is arranged at the lower end of the longitudinal rib 1, and the rest are arranged upwardly at a designed spacing. The steel bar limiting rings 3 match the diameter of the pole 11 at the position where they are located. At least two steel bar limiting rings 3 are provided. The steel bar limiting rings 3 are arranged on the inner side of the longitudinal rib 1 and abut against the longitudinal rib 1 to limit the distance between the longitudinal rib 1 and the outer surface of the pole 11. Each steel bar limiting ring 3 is a circular ring composed of two semicircular metal rings with connecting holes 4 at both ends connected by a pin 5, or each steel bar limiting ring 3 is a circular ring with an opening.

[0029] The steel cage is cylindrical or truncated cone-shaped with the same taper as the reinforced electric pole 11.

[0030] The number of the group of longitudinal ribs 1 is 6 to 20 and they are evenly distributed along the circumference.

[0031] The pitch of the beginning and the end of the group of annular ribs 2 is increased, and the pitch in the middle is 50mm-200mm.

[0032] The circular ring with openings is a structure with connecting holes at both ends, a connecting hole at one end and a pin at the other end, or a structure with straight sections at both ends.

[0033] The steel bar limiting ring 3 is provided with a positioning ring 8 or a positioning stop 9. The number of the positioning rings 8 or the positioning stop 9 is consistent with the number of the longitudinal bars 1 and is evenly distributed along the circumference.

[0034] When the steel bar limiting ring 3 is provided with a positioning ring 8 or a positioning stop 9, the longitudinal reinforcement 1 passes through the positioning ring 8 or rests on the positioning stop 9 to fix the position of the longitudinal reinforcement 1. When there is no positioning ring 8 or positioning stop 9 on the steel bar limiting ring 3 , the longitudinal reinforcement 1 is tied or welded to the steel bar limiting ring 3 .

[0035] When the steel bar limiting ring 3 is not in contact with the surface of the pole 11, it can still support the longitudinal bars 1, and can support the longitudinal bars 1 and the annular bars 2 to form a truncated cone or cylindrical steel bar cage with a diameter consistent with the design value.

[0036] The longitudinal ribs 1 or the steel bar limiting rings 3 are provided with outwardly protruding pads 7 for limiting the distance between the outer shape forming mold 12 and the longitudinal ribs 1 .

[0037] The single longitudinal reinforcement 1 is wound with a spiral steel wire 10, and the spiral outer diameter of the spiral steel wire 10 is smaller than the wall thickness of the high-performance reinforced concrete reinforcement structure.

[0038] In order to increase the bond strength between the high-performance concrete mortar 6 and the steel bars, a spiral steel wire 10 may be wound around some or all of the single longitudinal bars 1. The spiral outer diameter of the spiral steel wire 10 is smaller than the wall thickness of the high-performance reinforced concrete structure. When the spiral outer diameter of the spiral steel wire 10 is close to the wall thickness of the high-performance reinforced concrete structure, the spiral steel wire 10 may replace the protruding pad 7 provided on the longitudinal bar 1 or the steel bar limiting ring 3 to limit the distance between the outer shape forming mold 12 and the longitudinal bar 1. In this case, the protruding pad 7 may not be provided.

[0039] The lower end of the high performance reinforced concrete reinforcement structure is located between 0.3m and 1m below the ground, and the upper end extends to 0.6m to 2m above the ground. The specific size is determined according to the needs of the site.

[0040] The reasonable wall thickness of the high-performance reinforced concrete reinforcement structure should be smaller than the wall thickness of the reinforced pole 11 .

[0041] Due to the use of high-performance concrete mortar 6, the reinforced part has greatly improved its ability to resist erosion by corrosive media, frost heave and external force collision than the original pole 11. Due to the configuration of longitudinal reinforcement 1 and on-site wound annular reinforcement 2, it is equivalent to installing a section of high-performance concrete pole structure on the surface of ordinary pole 11, thereby greatly increasing the ability of the pole 11 to resist erosion by corrosive media, frost heave and external force collision, which is much higher than the strength of other reinforced structures. Because high-performance concrete is relatively expensive, using it in large quantities will increase the cost of pole 11, and ordinary concrete does not have anti-corrosion ability, has low anti-collision ability, and its resistance to penetration corrosion and frost heave is much lower than that of high-performance concrete. The two are reasonably matched and reinforced according to local conditions to achieve the best cost-effectiveness.

[0042] A method for manufacturing a pole root on-site forming reinforcement structure, characterized by comprising the following steps: Step 1: excavate a circular foundation pit at the root of the pole 11 according to the depth required for protection. When the foundation pit exceeds a certain depth, the pole 11 needs to be supported to prevent it from falling; Step 2: Install and fix the longitudinal ribs 1: (1) The steps for installing the longitudinal rib 1 of the steel bar limiting ring 3 with a positioning ring 8 or a positioning stop 9 are as follows: When the steel bar limiting ring 3 is two semicircular metal rings with connecting holes 4 at both ends, the two semicircular metal rings of each steel bar limiting ring 3 are surrounded on the outer surface of the pole 11 and connected through the pin 5 or the longitudinal rib 1 is used to replace the pin 5 and penetrate the connecting hole 4 to form a circular steel bar limiting ring 3. When the steel bar limiting ring 3 is a circular ring with an opening, the opening of the steel bar limiting ring 3 is opened, put on the electric pole 11, and then the opening is closed; When the steel bar limiting ring 3 is a circular ring with an opening, and the circular ring with an opening has a connection hole at one end and a pin at the other end, the pin 5 at one end is inserted into the connection hole 4 at the other end for connection; when the circular ring with an opening has connection holes 4 at both ends, the pin 5 is inserted or the longitudinal rib 1 is used to replace the pin 5 and inserted into the connection hole for connection to form a uniformly arranged structure of the longitudinal ribs 1 supported and positioned by the circular steel bar limiting ring 3;

[0043] When the steel bar limiting ring 3 is a circular ring with an opening and both ends of the circular ring with an opening are straight sections, a temporary pad is installed between the steel bar limiting ring 3 and the electric pole 11; The mutual positions of the steel bar limiting rings 3 are pulled apart and fixed at a set distance, and the longitudinal reinforcement 1 is inserted into the positioning ring 8 or abutted against the positioning block 9, and can be further tied and fixed if necessary; When a spiral steel wire 10 is provided on a single longitudinal reinforcement 1, the spiral steel wire 10 needs to be pulled to a set length first. If a positioning ring 8 is provided on the reinforcement limit ring 3, the spiral steel wire 10 and the positioning ring 8 are coaxially placed, and the longitudinal reinforcement 1 is inserted into the spiral steel wire 10 and the positioning ring 8 at the same time; If there is a positioning stop 9 on the steel bar limiting ring 3, the longitudinal reinforcement 1 is first inserted into the spiral steel wire 10, and then the longitudinal reinforcement 1 is pressed against the positioning stop 9; A uniformly arranged structure of longitudinal reinforcement 1 is formed, which is supported and positioned by a circular reinforcement limiting ring 3; (2) The installation steps for the steel bar limit ring 3 without a positioning ring 8 or a positioning stop 9 and the longitudinal reinforcement 1 needing to be tied or welded are: When a single longitudinal reinforcement 1 is provided with a spiral steel wire 10, the spiral steel wire 10 needs to be pulled to a set length first, and the longitudinal reinforcement 1 is inserted into the spiral steel wire 10. Then, the following operations are performed in the same manner as the longitudinal reinforcement 1 without the spiral steel wire 10: when the reinforcement limiting ring 3 is two semicircular metal rings with connecting holes 4 at both ends, the semicircular metal rings of each required reinforcement limiting ring 3 are placed and fixed at the set positions of the reinforcement limiting ring 3 to form a group of semicircular metal rings, and half of the longitudinal reinforcements 1 are tied or welded to this group of semicircular metal rings at the set positions. Every two semicircular structures including a group of semicircular metal rings and half of the longitudinal reinforcement 1 are placed opposite to each other to form a conical or cylindrical structure. The two semicircular structures are wrapped on the surface of the pole 11, and each pair of semicircular metal rings are connected with a pin 5. When the reinforcement limiting rings have connecting holes at both ends or the longitudinal reinforcement 1 is used instead of the pin 5 to penetrate into the connecting hole 4 for connection, a uniform arrangement structure of longitudinal reinforcements supported and positioned by the circular reinforcement limiting rings is formed; When the steel bar limiting ring 3 is a circular ring with an opening, each required steel bar limiting ring 3 is placed and fixed at a set position to form a group of steel bar limiting rings 3, and the required longitudinal ribs 1 are tied or welded to this group of steel bar limiting rings 3 at the set position, and all openings of a group of steel bar limiting rings 3 with longitudinal ribs 1 are opened, sleeved on the electric pole 11, and then the openings are closed. When the steel bar limiting ring 3 is a circular ring with an opening, and the circular ring with an opening has a connecting hole at one end and a pin at the other end, the pin 5 at one end is inserted into the connecting hole 4 at the other end for connection; when the circular ring with an opening has connecting holes 4 at both ends, the pin 5 is inserted or the longitudinal ribs 1 are used to replace the pin 5 to insert into the connecting holes to form a uniformly arranged structure of the longitudinal ribs 1 supported and positioned by the circular steel bar limiting ring 3; When the steel bar limiting ring 3 is a circular ring with an opening and the two ends of the circular ring with an opening are straight sections, a temporary pad must be installed between the steel bar limiting ring 3 and the electric pole 11 when the two ends of the steel bar limiting ring 3 are closed to prevent the steel bar limiting ring hoop from being tightly attached to the electric pole 11 during the subsequent annular reinforcement winding, so that the steel bar cage cannot move downward; Step 3: Winding of the hoop rib 2; The evenly arranged structure of the arranged longitudinal reinforcement 1 is lifted so that the steel bar limiting ring 3 at the lower end is located above the ground and supports it. If a temporary pad needs to be installed between the steel bar limiting ring 3 and the electric pole 11, it can also be installed at this time. The annular reinforcement 2 is spirally wound from bottom to top or from top to bottom on the surface of the longitudinal reinforcement 1 in the form of dense ends and uniform pitch in the middle to form a complete reinforcement cage. After the annular reinforcement 2 is wound, when the steel bar limiting ring 3 is a circular ring with an opening and the two ends of the circular ring with an opening are straight sections, the temporary pad installed between the steel bar limiting ring 3 and the electric pole 11 is removed, so that there is a certain gap between the steel bar limiting ring 3 and the electric pole 11, which is convenient for the steel cage to move downward; Step 4: Install the shape forming mold: Install the protruding pad 7 on the longitudinal rib 1 or the steel bar limiting ring 3 to limit the distance between the shape forming mold 12 and the steel bar. When the spiral outer diameter of the spiral steel wire 10 is close to the wall thickness of the high-performance reinforced concrete reinforcement structure, the protruding pad 7 may not be installed. Remove the support at the bottom of the steel bar limiting ring 3, sink the steel cage to the bottom of the foundation pit, and install the shape forming mold 12 on the surface of the steel cage. The step of installing the mold may be placed before the steel cage sinks to the bottom of the foundation pit. When the steel cage sinks, the mold sinks to the bottom of the foundation pit together with the steel cage. Step 5: High-performance concrete mortar 6 is formed; high-performance concrete mortar 6 is poured into the gap between the top of the mold and the pole 11 until the gap is completely filled, and the mold is removed after standing and curing until the high-performance concrete mortar 6 hardens, and the edges are trimmed. All work is completed after checking and confirming that it meets the standards. If the mold is a disposable mold made of corrosion-resistant thin plates, the high-performance concrete mortar 6 does not need to be removed after hardening.

[0044] The on-site formed reinforcement structure for the root of the electric pole of the present invention and the manufacturing method thereof can reinforce the parts of the electric pole 11 installed in the area with risk of damage, realize precise protection, control the cost and achieve the protection effect; this scheme is not only suitable for reinforcing the electric pole 11 in the running state, but also suitable for repairing the damaged electric pole 11, and can not only repair the above-ground part, but also repair the underground part at the same time, completely eliminating the safety hazard of the electric pole 11; compared with other repair schemes, the scheme provided by the present invention has more reliable reinforcement effect, simple installation, easy use and convenient construction. It is not necessary to replace the damaged electric pole 11, which can shorten the repair time, improve work efficiency, achieve non-stop power supply, and ensure safe power supply of the line.

If there is a positioning ring on the reinforcement limit ring, the spiral steel wire and the positioning ring are placed coaxially, and the longitudinal reinforcement is inserted into the spiral steel wire and the positioning ring at the same time; If there is a positioning stop on the steel bar limiting ring, first insert the longitudinal reinforcement into the spiral steel wire, and then place the longitudinal reinforcement 1 against the positioning stop; Form a uniformly arranged longitudinal reinforcement structure supported and positioned by a circular reinforcement limiting ring; (2) The installation steps for the steel bar limit ring without a positioning ring or positioning stop and the longitudinal reinforcement needs to be tied or welded are: When a single longitudinal reinforcement is provided with a spiral steel wire, the spiral steel wire must be pulled to a set length first, the longitudinal reinforcement must be inserted into the spiral steel wire, and then the following operations are performed in the same manner as the longitudinal reinforcement without a spiral steel wire: when the reinforcement limiting ring is two semicircular metal rings with connecting holes at both ends, the semicircular metal rings of each required reinforcement limiting ring are placed and fixed at the set positions of the reinforcement limiting rings to form a group of semicircular metal rings, and half of the longitudinal reinforcements are tied or welded to this group of semicircular metal rings at the set positions, and every two semicircular structures including a group of semicircular metal rings and half of the longitudinal reinforcements are placed opposite to each other to form a truncated cone or cylindrical structure, and the two semicircular structures are wrapped on the outer surface of the pole, and each pair of semicircular metal rings are connected with a pin shaft, and when the reinforcement limiting rings have connecting holes at both ends or longitudinal reinforcements are used instead of pin shafts to penetrate the connecting holes for connection, a uniformly arranged structure of longitudinal reinforcements supported and positioned by circular reinforcement limiting rings is formed; When the steel bar limiting ring is a circular ring with an opening, each required steel bar limiting ring is placed and fixed at a set position to form a group of steel bar limiting rings, the required longitudinal reinforcement is tied or welded to the group of steel bar limiting rings at a set position, all openings of a group of steel bar limiting rings with longitudinal reinforcement are opened, put on the pole, and then the openings are closed; When the steel bar limiting ring is a circular ring with an opening and one end of the circular ring with an opening has a connection hole and the other end has a pin shaft, the pin shaft at one end is inserted into the connection hole at the other end for connection; when the circular ring with an opening has connection holes at both ends, the pin shaft is inserted into the connection holes or longitudinal ribs are used to replace the pin shafts and inserted into the connection holes for connection to form a longitudinal rib uniformly arranged structure supported and positioned by the circular steel bar limiting ring; When the steel bar limiting ring is a circular ring with an opening and the two ends of the circular ring with an opening are straight sections, a temporary pad must be installed between the steel bar limiting ring and the pole when the two ends of the steel bar limiting ring are closed to prevent the steel bar limiting ring hoop from being tightly attached to the pole when the annular reinforcement is subsequently wound, so that the steel bar cage cannot be moved downward; Step 3: Circumferential reinforcement winding; The evenly arranged structure of the longitudinal reinforcement is lifted so that the steel bar limiting ring at the lower end is located above the ground and supported, and the annular reinforcement is spirally wound from bottom to top or from top to bottom to the surface of the longitudinal reinforcement in the form of dense ends and uniform pitch in the middle to form a complete steel cage. After the annular reinforcement is wound, when the steel bar limiting ring is a circular ring with an opening and the two ends of the circular ring with an opening are straight sections, the temporary pad installed between the steel bar limiting ring and the pole is removed, so that there is a certain gap between the steel bar limiting ring and the pole, which is convenient for the steel cage to move downward; Step 4: Install the shape forming mold: Install a protruding pad on the longitudinal rib or the steel bar limiting ring to limit the distance between the shape forming mold and the steel bar. When the spiral outer diameter of the spiral steel wire is close to the wall thickness of the high-performance reinforced concrete structure, the protruding pad is not installed. Remove the support at the bottom of the steel bar limiting ring, sink the steel cage to the bottom of the foundation pit, and install the shape forming mold on the surface of the steel cage; the step of installing the mold may be placed before the steel cage sinks to the bottom of the foundation pit. When the steel cage sinks, the mold sinks to the bottom of the foundation pit together with the steel cage; Step 5: High-performance concrete mortar molding; pour high-performance concrete mortar into the gap between the top of the mold and the pole until the gap is completely filled, let it stand and cure until the high-performance concrete mortar hardens, then remove the mold, trim the edges, and check to confirm that it meets the standards before completing all the work. If the mold is a disposable mold made of corrosion-resistant thin plates, the high-performance concrete mortar will not be removed after hardening.
