[0039] The construction method using the operating platform of the utility model suitable for cast-in-place piles for installing cast-in-place pile reinforcement cages and conduits comprises the following contents:

[0040] 1. Preparation before construction

[0041] 1) After the hole reaches the designed elevation, the hole depth, hole diameter, hole wall, verticality, etc. are checked. The hole diameter and inclination are measured by a hole detector. The next step can be carried out only after the inspection is qualified.

[0042] 2) The site should be connected, connected and leveled, all obstacles above and below ground should be dealt with, and all temporary facilities such as lighting, power and safety facilities should be ready.

[0043] 3) If the bearing capacity of the surrounding foundation is weak, a 6mm thick steel plate should be prepared to improve the ground stability if necessary.

[0044] 4) Before construction, investigate the line's vehicle traffic, pedestrian flow, and pipelines and obstacles around the construction area. If there are any conflicting locations, please provide timely feedback.

[0045] 5) Carry out safety and reliability inspections and tests on cranes, drilling rigs, etc. that have entered the site to ensure safe and reliable construction.

[0046] 6) During the lifting construction period, vehicles must be strictly prohibited from passing through the operation area.

[0047] 2. Construction technology

[0048] After the hole inspection and acceptance is qualified → install the base support → hoist the first section of the steel cage (the steel cage is processed in the processing plant and then transported to the site) → hang the steel cage on the steel cage clamping mechanism of the base support → connect the first and second sections of the steel cage through a straight threaded sleeve → hang the steel cage as a whole in the clamping slot → fix the conduit support mechanism on the base support → install the conduit → clean the hole once and twice → after qualified acceptance → pour concrete → pile inspection and acceptance.

[0049] 3. Construction technical requirements

[0050] 1) It can be hoisted using the hoisting rings set diagonally on the base.

[0051] 2) There is an adjustable length steel cage clamping mechanism on both sides of the bottom bracket, and the stability of the steel cage can be controlled by adjusting the length. The positioning chamber is hollow, and bolts are set on it. Tightening can achieve positioning and locking. Anti-falling ears are set on the outside to prevent locking and falling, which is more secure.

[0052] 3) Two groups of symmetrical catheter positioning plate positioning holes are arranged on the bottom bracket to ensure stable connection with the catheter positioning plate.

[0053] 4) The conduit is locked in place by two rotatable support plates and a raised portion. After the new section of conduit is installed, the support plate is opened by the handle to allow the conduit to fall to a certain distance, and then the conduit is locked and the next section is installed.

[0054] 5) The support plate is connected to the adjacent positioning plate by a rotating device (in this embodiment, a hinge connection can be adopted), and the rotating device should be anti-blocking and ensure smoothness.

[0055] 6) Do not lift the conduit too quickly or too hard to prevent the surface concrete from being dragged along and causing the intrusion of slurry and slag, or hanging the steel cage, etc. The conduit removal operation should be clean and neat to prevent the sealing ring from falling into the hole. The removed conduits should be rinsed with clean water and stacked together.

[0056] 7) To prevent the steel cage from floating during pouring, reduce the pouring speed when pouring to 1m from the bottom of the steel cage. When the top surface of the concrete rises to more than 4m from the bottom of the steel cage, it is advisable to lift the conduit so that the bottom of the conduit is more than 2m above the bottom of the steel cage before resuming the normal pouring speed.

[0057] 4. Finished product monitoring

[0058] 1) The curing time of cast-in-place pile concrete should not be less than 28 days. When the pile top is in the mud, the curing time should be no less than 7 days; when the pile top is above the ground, it should be covered and watered for curing for no less than 7 days.

[0059] 2) The pouring elevation of the pile top should be 0.5 to 1.0 m higher than the designed pile top elevation to ensure that the concrete at the pile top reaches the designed concrete strength. After pouring, mark the pile position to prevent vehicles or mechanical equipment from rolling over and damaging the pile head.

[0060] 3) During winter construction, when the pile top elevation is below the local freezing line, it should be covered with soil or mud for maintenance; when the pile top is above the freezing line, in addition to adding antifreeze to the concrete, rice husks, sawdust and plastic film should be used for covering.

[0061] Parts not involved in the present invention are the same as the prior art or can be implemented by the prior art. Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the attached claims and their equivalents.
