However, during the pile foundation construction process, especially in the construction stage of bored cast-in-place piles, the safety protection problem of the pile foundation orifice is particularly prominent.

[0003] The existing protection measures often use simple wooden boards or iron sheets for shielding. These measures not only have limited protection effects and are easily damaged by wind, sun and rain, but more importantly, they cannot effectively prevent vehicles, pedestrians or large construction machinery from accidentally entering the orifice area, thus leading to serious safety accidents. The pile foundation orifice is exposed outside and is also likely to attract sundries into the hole, such as soil, stones, construction waste, etc.

[0004] The protection effect is limited and it is easy to be damaged, which may easily lead to serious safety accidents; the pile foundation orifice is exposed outside, and sundries are likely to be mixed in, polluting the internal environment of the pile foundation orifice, disturbing the hole wall and causing the hole wall to collapse; sundries are mixed in the pile foundation orifice, affecting the hole forming quality and construction progress of the pile foundation orifice.

[0007] Preferably, the outer ring main reinforcement bars surround the framework structure for one week, and the outer ring main reinforcement bars completely cover the pile foundation orifice, playing a role in safety protection for the pile foundation orifice.

[0008] Preferably, the inner ring main reinforcement bars are arranged in the middle part of the framework structure, and the outer ring main reinforcement bars are arranged on the outside of the framework structure.

The longitudinal frameworks and the transverse frameworks are used for structural load-bearing, making the structure tightly connected.

[0010] Preferably, one end of the fixator is fixedly connected to the main outer ring reinforcement bars, and the fixator is a part where the longitudinal skeleton extends out from the main outer ring reinforcement bars and bends downward. When the protection device is placed on the pile foundation, the fixator is fixedly connected to the steel casing of the bridge pile foundation for limiting the protection device.

Moreover, since this protection structure adopts a grid structure and a construction opening 4 is reserved at the central position of the protection device, tools such as impact drills can be constructed normally through the construction opening 4, improving the construction efficiency of the project; the structure is simple, the steel bars can be welded according to the drawings, the material consumption is small, the process is few, and it can be reused, further reducing the cost; it can manufacture pile foundation protection devices of different shapes and can appropriately adjust the number and density of steel bars in the skeleton structure 2 according to different requirements to adapt to bridge pile foundations in various different states; high safety: this protection device for the orifice of a pile foundation adopts a "C" - shaped design, and there is a fixator 3 at the edge extending and connecting to the steel casing 5 of the bridge pile foundation, playing a fixing role, which can effectively avoid accidents such as the device falling off and improve the safety of construction workers.

[0026] Furthermore, the outer ring main reinforcement 11 surrounds the skeleton structure 2 for one week, and the outer ring main reinforcement 11 completely covers the orifice of the pile foundation, playing a role in safety protection for the orifice of the pile foundation.

[0030] It should be particularly emphasized that the construction opening 4 is a circular hole formed inside the inner ring main reinforcement 12.

[0031] Working principle: The outer ring main reinforcement 12 surrounds the framework structure 2 for one week, determining the overall shape of the protection device. The size and shape of the protection device can be adjusted at any time according to the size and shape of the pile foundation, so that the device completely covers the pile foundation orifice, playing a role in safety protection; the framework structure 2 is mainly composed of several steel bars of different lengths welded in a grid shape on the outer ring main reinforcement, which is the main load-bearing structure of the protection device, making the connection tight and the integrity strong.
