Further setting: the through-hole passed through for tup and equipment is provided on the footstock.
So set, equipment and tup is made to avoid the interference by footstock during installation.
Further setting: the mounting hole for fixed column insertion is offered in the lower end surface of the footstock.
So set, mounting hole is inserted by fixed column, to realize the installation and fixation of footstock.
Further setting: the pedestal is equipped with the fixing glue of insertion underground.
So set, to play firm effect to pedestal, avoiding occurring because of vibration partially by the way that ground nail to be driven underground
It moves and influences its stability.
Further setting: being inserted with ground nail on the ground, is connected between the ground nail and the footstock by wirerope.
So set, footstock is enabled to push against under the pulling force of steel wire with support frame, while leading truck is integrally applied
Downward pressure improves leading truck in working condition to limit each support frame along the axial movement of fixed column
Stability.
Further setting: the footstock is provided with the fixed ring for wirerope connection.
So set, realizing the connection of footstock and wirerope by setting fixed ring.
In conclusion the utility model has the following beneficial effects:
1. pile foundation strong strain guide body structure is simple, it is convenient to build, and can adjust height according to actual needs；
2. pile foundation strong strain guide body structure is stablized, connection is reliable.
