Description

Device for preventing PHC hollow pipe pile soil from dropping

Technical Field

The utility model relates to a building equipment technical field specifically is a device that prevents hollow tubular pile earth of PHC and drop.

Background

1. The PHC tubular pile sinking method has various methods, and the construction method commonly used in the construction of China comprises the following steps: hammering method, static pressure method and pre-drilling method, but the static pressure method is mainly used for construction. The static pile press can be divided into a top press type and an embracing type, the embracing type is that a clamping plate of the pile press clamps a pile body, the pipe pile is pressed to a holding layer required by design by depending on the principle that the friction force of the holding plate is larger than the resistance to soil penetration, but the top press type construction is mainly used, and particularly in regions with poor soil conditions (mucky soil, peat soil and the like), the top press type static pile press is often selected to construct the PHC pipe pile.

2. No matter which construction method is adopted for constructing the PHC tubular pile, the PHC tubular pile is often conveyed to a designed elevation in a pile conveying mode in order to avoid the disturbance of the construction machinery to the foundation earthwork due to the heavy dead weight of the construction machinery. However, in the pile feeding process, if no effective measures are taken, soil, gravels and the like in the earthwork can fall into the PHC tubular pile core to block the pile core, and the soil, the gravels and the like can block the pile core in the subsequent earthwork excavation process. And in the later stage, constructors are arranged to clear the pile cores, so that the labor is large, the construction is slow, the clearing effect is not ideal, and the like.

3. Other protection devices for preventing impurities from falling into the interior of the PHC prestressed pipe pile mainly install a supporting plate of a pile core reinforcement cage in the pile core in advance, and adopt measures such as welding or a nail gun for reinforcement, wherein the welding workload is large, constructors need to operate the lower part of a pile feeder of the pile machine for a long time in the construction process to have large potential safety hazards, and certain potential safety hazards such as fire disasters and electric shocks also exist in the welding process. The nail gun is adopted for fixing, so that the defects that the pile body is damaged to a certain degree and is not easy to remove exist.
