Description

Technical Field

[0001] The present invention belongs to the technical field of pile construction, and particularly relates to a composite top-holding and pressing integrated static pressure pile construction equipment and construction method. Background Art

[0002] The existing foundation reinforcement is a technical requirement widely applied in the domestic and foreign construction industries in recent years. When carrying out foundation treatment under an existing building, not only should the foundation bearing capacity of the original building be improved by means such as pile driving, but also it is necessary to ensure that during construction, the soil body is not disturbed and the bearing capacity of the original building is not reduced. When constructing in the underground space of an existing building, due to the limitation of space size, the construction equipment cannot be made very large. However, the diameter requirements of the pile holes are getting larger and the construction depth is getting deeper, which requires very high requirements for mechanical equipment, otherwise construction cannot be carried out. When the existing static pressure pile equipment clamps the drilling tool and presses it into the ground, the clamping force is often insufficient, resulting in the phenomenon of pulley, and repeated clamping and pressing are required, increasing the construction time and reducing the efficiency; there are also equipment that can be used for both top pressing and holding pressing, which requires the combined action of large machinery such as large spaces, gantry cranes and cranes; moreover, it cannot carry out adaptive construction according to the size of the pile body diameter.
