Technical Field
The invention belongs to the technical field of pile foundations, and particularly belongs to a pile end exposed steel bar bending prevention device and a using method thereof.
Background
The pile foundation is a common deep foundation form, which consists of a foundation pile and a bearing platform connected to the top of the pile. If the pile body is completely buried in the soil and the bottom surface of the pile cap is in contact with the soil body, the pile body is called a low pile cap pile foundation, and if the upper part of the pile body is exposed out of the ground and the bottom of the pile cap is positioned above the ground, the pile body is called a high pile cap pile foundation. Building pile foundations are typically low-cap pile foundations, while high-cap pile foundations are commonly used in bridge and pier engineering. The precast pile is prefabricated in various forms in factories or construction sites in advance, and is driven, pressed or vibrated into the soil by pile sinking equipment or sunk into the soil by high-pressure water jet. Depending on the method of sinking into the earth, driven piles (hammer driven piles), water jet driven piles, vibration driven piles, static pressed piles and the like can be used. The cast-in-place pile is formed by mechanically or manually forming a hole in a pile position on a construction site, placing a steel reinforcement framework in the hole and then pouring concrete into the hole. According to different hole-forming methods, the method is divided into hole digging, drilling and punching cast-in-place piles, sleeve pipe hole-forming cast-in-place piles (immersed tube cast-in-place piles), explosion-expanded hole-forming cast-in-place piles and the like. No matter adopt precast pile or bored concrete pile, can reserve one section reinforcing bar at pile bolck position for later stage and the connection of cushion cap or extension steel reinforcement cage increase pile length, but generally by the pile shaping to construction process on next step, there is certain time interval in the middle of, in this period, the reinforcing bar will receive external various influences, the bending of different degrees, deformation etc. appear, it is more troublesome to handle in the later stage construction, not only extravagant manpower but also influence the time limit for a project.
