Description

Rotary digging hole-forming cast-in-place pile hole protecting device Technical Field The utility model relates to the field of bored concrete pile hole protection, in particular to a rotary digging hole-forming bored concrete pile hole protection device. Background The rotary drilling bored concrete pile hole is formed by rotary drilling at a preset position through a rotary drilling machine, is mainly used for forming bored concrete piles, so as to increase the bearing capacity of a foundation, improve the stability and lateral force resistance of the foundation, and is widely applied to foundation engineering of railways, highway bridges, municipal construction, high-rise buildings and the like due to the advantages of high construction speed, high pore-forming quality, small environmental pollution, flexible and convenient operation, strong applicability and the like. The existing rotary digging hole-forming bored concrete pile hole is usually not internally protected after hole forming, and is easy to collapse, fall and other safety accidents when being placed for a long time or constructors construct the inside, or is easy to drop into the pile hole carelessly when people pass at night, so that the safety is lower. Therefore, aiming at the problems that the existing rotary drilling bored concrete pile hole generally has larger potential safety hazard and lower safety, the rotary drilling bored concrete pile hole protecting device with an internal setting structure and an external protecting structure can be designed, and can double protect the pile hole from inside and outside no matter when the pile hole is idle or when a worker performs construction in the interior, so that the rotary drilling bored concrete pile hole protecting device is safer and more reliable. Disclosure of utility model In order to solve the problems that the existing rotary digging hole-forming bored concrete pile hole generally has larger potential safety hazard and lower safety. The technical scheme includes that the rotary digging hole-forming bored concrete pile hole protection device comprises an inner supporting component and an outer protection component, wherein the inner supporting component is sequentially arranged along the inner wall of a pile hole from top to bottom and used for supporting the inner wall of the pile hole, the number of the inner supporting components is flexibly arranged according to the depth of the pile hole, the upper end of the inner supporting component is provided with the outer protection component used for preventing personnel from carelessly falling and preventing objects from falling into the pile hole, and the outer protection component is detachably arranged on the ground outside the pile hole.
