Problems solved by technology
In the traditional technology, the clamping parts of the pile-pressing equipment clamp the pile and then apply force to realize the pile pressing. The clamping parts are usually controlled by a common power drive device, so different clamping parts The clamping force exerted by the column and the upward and downward control force are basically the same. In this implementation, the stress effect inside the column is ignored, because the internal structure of the column is not exactly the same and may Different parts are blocked by different obstacles, so the force inside the main body is unbalanced. In this case, if the force on the outside of the pile is the same, the column may be damaged during the pile pressing process. The imbalance of internal stress is amplified again, which may cause inefficient pile pressing, tilting of pile pressing and even damage or fracture of pile

The invention discloses a pressure pile structure for construction engineering. The invention includes a plurality of power assemblies arranged in a circular matrix around the construction station of the pile column, and is used to control the control assembly of the power assembly. Each power assembly The control assembly is connected with the control line, and the power assembly includes a first adjustable force assembly configured to provide vertical forces of different sizes and a claw configured to clamp the pile body during the pile pressing process. The first adjustable The upper end of the force adjustment component is connected to the second adjustable force component, and the power output shaft of the second adjustable force component is connected to the claw. The contact part of the claw and the pile body is provided with an arc groove, and the arc groove is fixed For the force sensor, a base is provided at the bottom of the first adjustable force component. During the pile pressing process, the force sensor set on the claw can measure the force on the claw on the powertrain in real time, and measure the pressure in detail, and compare the common values of the force sensor to know whether the measured pressure is balanced and know the pile body. Whether the distribution of internal transverse stress is balanced.
Description
Technical field [0001] The present invention relates to a construction field device, in particular a pile construction works with a press. Background technique [0002] In a related prior art, such as background art content Chinese utility model patent CN201120539320.6 A press mechanism and the pile and pile pressing pile clamping jaw apparatus disclosed conventional hydraulic static pile driver pile by sandwiching the pile gripping mechanism. Wherein the pile clamping means comprises two jaws clamp the device along the longitudinal direction of the pile of the pile is provided, each clamp jaw means around the pile the pile circumferentially uniform. For example each pile gripper jaw means may comprise four sets of two jaws opposite pile clamping means, each jaw clamp means comprises a pile and pile clamping jaw cylinder, cross-sectional profile of the jaw clamping surface and substantially concentric arcuate cross-section of the pile. Jaw cylinder mounted on the pile gripper, an...
