Stake of drainage static tube

The utility model provides a pair of stake of drainage static tube, including the tubular pile a plurality of wash ports have been seted up on the pile lining of tubular pile, does the wash port slopeset up, its relative pile lining slope 20 60. Simple structure, convenient operation possesses water discharge ability for stake zhou tuti's consolidation in the work progress, owing to make in holewater that stake zhoututi produced will flow into the tubular pile in the same direction as the wash port soil body extrusion, should flow into that water will follow that a point infiltrates to the stratum of below in or evaporated or artifical the discharge by the atmosphere, had accelerated the soil body and had solidified and significantly reduced and get into the soil volume in the tubular pile, reduce the porosity of the soil body simultaneously, made it to expand a space that holds the nanotube stake, reduced the extrusion effect to surrounding soil. 本实用新型提供的种排水静压管桩，包括管桩，在所述管桩的桩壁上开设有多个排水孔，所述排水孔倾斜设置，其相对桩壁倾斜20°-60
