Embodiment Construction
[0028] The present invention will be further described below in conjunction with the accompanying drawings and implementation steps.
[0029] Such as figure 1 As shown in , it is a cross-sectional schematic diagram of the weak soil foundation treated by the ground anchor counter force loading preloading method. The invention is divided into two parts, a specially designed ground anchor and a soft soil foundation counter force loading preloading method based on the ground anchor.
[0030] The ground anchor includes a conventional ground anchor 1, the main difference of which is that the upper part of the ground anchor 1 shaft is provided with a force component and a counter force loading device, and the counter force loading device applies an upward pull to the ground anchor 1 through the force component. Force, using the pull-out resistance of the ground anchor itself, and transmitting the reaction force of the pull-up force to the bottom of the reaction force loading device ...
