It is internal diameter with the cone shape extended from the front end terminad of hollow steel tube.Preferably, described every grade is fallen snatch by multiple
Snatch valve forms.Or every grade fall snatch be ring overall structure.
Pressure surface is arranged to cone shape, and the cone of circular cone makes anchor pole into the soil body towards the front end of hollow steel tube
During insertion, the component of radial direction can be produced on pressure surface, anchor pole is more smoothly inserted into the soil body, incited somebody to action
After in the anchor pole insertion soil body, because retaining face is the plane or cone orthogonal with the central axis of hollow steel tube towards hollow steel tube
Front end it is coniform, the soil body can form the resistance for avoiding anchor pole from exiting the soil body on retaining face, make anchor pole and the soil body have compared with
Strong adhesion.
Preferably, electric heating body is additionally provided with hollow steel tube, after seal cap is drawn in the power supply linear sealing of electric heating body
It is connected with the power connection for connecting external power source.Electric heating body can be used for the temperature for improving the soil body, promote the water in the soil body
Shunting is dynamic, the discharge for the moisture that can be effectively facilitated in the soil body, improves the mechanical characteristic of the soil body.
Anchor pole of the present utility model can carry out vacuum drainage reinforcing to soft soil foundation, make the water content of soil around anchor pole
Lower significantly, so as to the Zeng Qiang mechanical characteristics of anchor pole surrounding soil, the anchor of anchor pole is ensure that in combination with the snatch of falling of anchor pole
Gu power.In addition, also having electric heating body in anchor pole, soil temperature is improved using electric heating body, promotes the water flowing in the soil body, from
And further improve stabilization by drainage speed and effect.
