The utility model aims to overcome the problems of long construction period, large potential safety hazard, no guarantee of construction quality and serious resource waste in the existing cast-in-situ bored pile construction, and provides a rotatable operating platform for cast-in-situ bored pile construction, which comprises a platform, a ridge platform, a protective guard and a hanging ring; the middle part of the platform is provided with a hole; the ridge platform and the guard rail are respectively arranged at the upper end of the platform along the circumferential direction of the hole; the lifting ring is provided with at least two lifting rings which are uniformly and symmetrically arranged on the platform.

Further, the platform is a reinforced concrete platform, and reinforcing steel bars are arranged in the reinforced concrete platform; and the lifting ring is bound or welded with the steel bar.

Further, the protective guard is arranged on the outer side of the sill table.

Further, the platform and the ridge platform are of an integrated structure.

Furthermore, a plurality of mounting holes are formed in the upper end of the platform along the circumferential direction of the hole; the lower end of the guard rail is connected with the mounting hole in a socket and spigot mode.

Further, the hole is a circular hole or a rectangular hole.

Further, the reinforcing steel bars are double-layer bidirectional reinforcing steel bar meshes.

Furthermore, four lifting rings are arranged at the upper end of the platform respectively; the upper end of the platform is provided with a notch convenient to hoist at the position of the hanging ring.

The utility model has the advantages that: compared with a traditional platform which is integrally hardened in a construction site, the prefabricated turnover operation platform is lower in cost, the whole hardened part of the site does not need to be broken, the turnover operation platform can be used repeatedly, resources are saved, a cast-in-place concrete curing period does not exist, and the construction efficiency is improved; the construction operation platform can be guaranteed to be firm and stable, and guarantee is provided for the construction of the high-precision upright post pile by the reverse construction method; through the effect of bank platform and rail guard, can realize drilling bored concrete pile hole protection, prevent that personnel from weighing down and mud excessive, promote the finished product protection, prevent that the stand pile from being disturbed.

Detailed Description

The invention is described in further detail below with reference to the figures and the specific embodiments.

As shown in fig. 1 to 4, the reusable operating platform for cast-in-situ bored pile construction includes a platform 1, a ridge platform 2, a guard rail 3 and a lifting ring 4; the middle part of the platform 1 is provided with a hole 5; the sill table 2 and the protective guard 3 are respectively arranged at the upper end of the platform 1 along the circumferential direction of the opening 5.

The platform 1 is preferably a reinforced concrete platform, and reinforcing steel bars 6 are arranged in the platform; the hanging ring 4 is bound or welded with the steel bar 6. In the embodiment, four lifting rings 4 are arranged and are respectively and uniformly and symmetrically arranged at the upper end of the platform 1; the upper end of the platform 1 is provided with a notch 8 convenient for hoisting at the position of the hoisting ring 4.
