Debris or soil falls into the hole, resulting in excessive sediment at the bottom of the hole, requiring secondary or even multiple cleanings. The top of the steel cage sinks as a whole, making connection difficult or falling completely into the hole, resulting in waste piles, seriously affecting the quality of the project.

[0018] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and the best embodiment.
[0019] Figure 1-2 A cast-in-place pile construction platform is shown, comprising a base 9, a pile seat 1 connected to the base, a cover plate structure mounted on top of the pile seat, and a lifting structure. The cover plate structure consists of two cover plates 10 hingedly connected to the top of the pile seat. A hole 11 for inserting a guide tube is provided in the middle of the cover plate structure. Channel steel holes 5 are provided on the pile seat for inserting channel steel. A cover plate lifting ring 2 is provided adjacent to the two cover plates. Warning signs 6 are provided on the cover plates.
[0020] The hoisting structure includes an angle steel 7 connected to the pile seat and a hoisting U-shaped clip 8 arranged on the angle steel.
[0021] Figure 3-4 A steel cage construction device is shown, comprising the cast-in-place pile construction platform and a steel cage arranged in the cast-in-place pile construction platform.
[0022] The steel cage is composed of multiple vertically connected segments. Each segment includes multiple main bars a-3, spiral stirrups a-2 connecting the main bars, cage locating bars a-1, and cage suspension bars a-4. The main bars between adjacent segments are connected using mechanical connection sleeves a-6.
[0023] A conduit b-2 is provided in the steel cage; the conduit is placed in the hole of the sealing plate structure.
[0024] The construction process of the utility model is as follows: during the bored pile construction, the pile foundation is put into use after the hole is completed; after ensuring that the compacted soil a-5 at the pile hole meets the lifting requirements, the bored pile construction platform (hereinafter referred to as the platform) is hoisted to the pile hole through the lifting device, ensuring that the center of the platform coincides with the center of the pile hole. Ensure that 1 (the platform foundation) is tightly attached to the compacted soil a-5 at the pile hole, and open the two sealing plates through the sealing plate lifting ring 2. At this time, the warning signs 6 on the sealing plates are simultaneously put into use to improve the safety of the subsequent construction process;
[0025] After the first cage section is lowered, insert the channel steel 3 into the channel steel hole 5 using the channel steel lifting ring 4. At the same time, insert the cage lifting rod a-4 to secure the cage, and then hoist the next cage section. Use the mechanical connection sleeve a-6 to manually connect the two cage sections. Once connected, lower the cage, repeat the hoisting and connection of the cage sections until all cages are installed.
[0026] After the conduit passes the watertightness test, it is installed. The two sealing plates are closed using a sealing plate hoisting ring, effectively securing conduit b-2. A pump truck is then used to pour concrete for pile foundation b-1. After this pile foundation is completed, the platform is moved to the next location using a hoisting device for future use.
[0027] To sum up, the bored pile construction platform of the present invention is mainly used in the process of connecting the steel cage after the pile foundation is bored. First, the unloading area within a certain range outside the pile hole is increased by the base of the device, which effectively disperses the influence of the deadweight of the pile foundation steel cage and reduces or avoids the collapse of the soil at the hole mouth; second, the channel steel holes are passed through the channel steel and the top suspension bars of the steel cage are fixed to ensure the stability of the connected steel cage sections, thereby improving the connection efficiency of the pile foundation steel cage and avoiding the collapse of the hole caused by too long waiting time for pouring after the hole is bored; third, the safety of the construction process is guaranteed by the safety warning signs on the cover plate of the device; fourth, during the concrete pouring process, the top cover plate of the platform is fixed to the conduit, and the conduit is stabilized for convenient pile concrete pouring.
[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
