Cross connector to be fixedly connected with the described purlin that encloses.
On the basis of technique scheme, this utility model can also do following improvement.
Further, the depth that described channel-section steel stake squeezes in described foundation ditch subsoil body is more than 0.8 times of foundation depth.
Further, the described anchor tube inserting in the described foundation pit side-wall soil body is 10-25 ° with the angle of horizontal plane.
Further, the described some anchor tubes inserting in the described foundation pit side-wall soil body are parallel to each other.
Further, the tube wall of described anchor tube offers some slurry outlets, the tube wall near described slurry outlet is provided with down
Thorn.
Further, if described girth purlin is horizontally disposed channel-section steel.
Further, described channel-section steel stake and the described connected mode enclosing purlin are welding or bolt connection.
Further, the described purlin and the connected mode of described connector of enclosing is welding.
Compared with prior art, the beneficial effects of the utility model are: the soil nail wall using channel-section steel stake and anchor tube combination props up
Protection structure, can solve the deficiency that soil nailing cannot be applied in weak soil, play the feature of channel-section steel front cover, have impervious and anti-foundation ditch
The effect that the soil body slides, anchor pipe soil nail low cost simultaneously, channel-section steel can all recycle and reuse, better economic benefit.
