Stability underground pipe fixation after then ensure that.
The arc air discharge duct 4 is distributed in 101 edge of the cylindrical structural using circumference array, and quantity is 4～8,
Thoroughly solve during down tube due to aerofluxuss smooth caused by hair fastener phenomenon (hair fastener phenomenon be traditional underground pipe Double-U-head due to
Without air discharge duct, the air during down tube in pore cannot be discharged in time causes air pressure to raise so that tubing down tube is difficult, drift
Float the phenomenon for easily snapping into pore inwall for waving and bumping against the appearance of pore inwall), simultaneously because increased air discharge duct and reduce
Buried pipe volume, so as to cause the buoyancy suffered by underground pipe to reduce, reduce further the resistance of down tube, improve work effect
Rate；4 radian of arc air discharge duct is R25mm, it is ensured that the circumference wall thickness of body can so reach reduction in 15mm～25mm
Resistance, the purpose for solving hair fastener phenomenon, can guarantee that the thickness of body itself again so as to reaching long-lived purpose.
1 a diameter of 135mm～145mm of the body, highly be 180mm～250mm, than traditional underground pipe Double-U-head entirety
120mm is highly shortened, 1/3 material cost on the premise of not affecting using function, is saved, simultaneously because the contracting of volume
The little reduction for causing suffered buoyancy, reduce further the resistance of down tube, and brings great convenience to transport；Described
3 outer diameter of connecting insertion is 25mm～32mm, is highly 40mm, when 3 outer diameter of the connecting insertion is 25mm, described
1 a diameter of 135mm of body；When 3 outer diameter of the connecting insertion is 32mm, 1 a diameter of 145mm of the body.
Operation principle of the present utility model is：4 connecting insertions of this utility model are interconnected by inner chamber, therein
Two intubations of meaning connect two water inlet pipes, and other two connects two outlet pipes, without deliberately distinguishing water inlet and outlet
Connected mode, it is to avoid the water caused because of wrong intake-outlet cannot circulatory problems.Body is formed in one, it is to avoid each
Due to connecting the improper leak gas leak phenomenon for causing between split, body bottom is conical structure, this pyramidal structure reduction
Resistance during down tube, conical structure bottom are circular horizontal plane, then ensure that underground pipe fix after stability.Body side
Edge is provided with arc air discharge duct, thoroughly solve during down tube due to aerofluxuss smooth caused by hair fastener phenomenon, simultaneously because increasing
Air discharge duct and reduce buried pipe volume, so as to cause the buoyancy suffered by underground pipe to reduce, reduce further the resistance of down tube
Power, substantially increases work efficiency；Arc air discharge duct is shaped as to tubular body depression circular arc, and radian is R25mm, it is ensured that pipe
The circumference wall thickness of body can so reach the purpose for reducing resistance, solving hair fastener phenomenon, can guarantee that body again in 15mm～25mm
The thickness of itself is so as to reaching long-lived purpose.This utility model underground pipe Double-U-head is more whole than traditional underground pipe Double-U-head simultaneously
Body highly shortens 120mm, on the premise of not affecting using function, saves 1/3 material cost, and due to volume
Reducing causes the reduction of suffered buoyancy, reduce further the resistance of down tube, also brings great convenience to transport.
