Abstract
The utility model discloses a soil layer anchor rod used for supporting a deep foundation pit, comprising a rod body, wherein, the head of the rod body is provided with a clamp nut; an anchor head pad is arranged on the rear of the clamp nut; and a beam channel is arranged between the anchor head pad and the foundation pit wall. The soil layer anchor rod used for supporting the deep foundation pit has a reasonable structure and good effect when used for enclosing the deep foundation pit.
Description
Technical field:
The utility model relates to a kind of deep pit support protection unit.
Background technology:
To going along with sb. to guard him of deep foundation ditch is a difficult problem in the construction for a long time always, and the existing mode of going along with sb. to guard him causes that through regular meeting phenomenon such as deep foundation ditch landslide takes place.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and is used for the effective deep foundation pit support soil bolt of Extra-Deep Foundation Pit.
Technical solution of the present utility model is:
A kind of deep foundation pit support soil bolt is characterized in that: comprise the body of rod, the head of the body of rod loads solid nut, is provided with the anchor head backing plate behind clamp nut, is provided with channel-section steel between anchor head backing plate and the foundation pit walls.
The utility model is rational in infrastructure, is used for Extra-Deep Foundation Pit effective.During construction, earlier at the foundation pit side-wall rat holing, insert pull bar then in the hole, the cement injection mortar carries out prestressed stretch-draw anchor in case of necessity again.When being subjected to external load, rock bolt head passes to anchor pole to external load, pulling force is delivered in the mortar (being anchoring body) by the bond stress u of reinforcing pull rod periphery mortar, anchoring body passes to the power from pull bar in the anchoring stratum by stratum frictional resistance again, has guaranteed that the anchoring stratum still can keep resistance to overturning under worst condition.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the configuration diagram of an embodiment of the utility model.
The specific embodiment:
A kind of deep foundation pit support soil bolt comprises the body of rod 1, and the head of the body of rod 1 loads solid nut 2, is provided with anchor head backing plate 3 behind clamp nut 2, is provided with channel-section steel 4 between anchor head backing plate 3 and the foundation pit walls 5.Also has mortar (anchoring body) 6 among the figure.
