Preferably, the both sides of outer muscle pipe and corresponding lobe appearance hot-melt adhesive paste.
Preferably, height of the height of outer muscle pipe less than lobe.
Preferably, outer muscle pipe be in hollow form structure, inside outer muscle pipe only one of which cavity or by perpendicular muscle be separated into
Few two cavitys.
Preferably, lobe is internally provided with perpendicular rib, and by perpendicular rib by bossing every in two cavitys, or lobe
Cross rib is provided with inside, cross rib is by bossing every in four cavitys.
Preferably, lobe is provided with perpendicular rib, winding unit is to erect the center vertical face of rib to wind interface, winding
The internal lobe that a perpendicular rib is only set is docked and is formed after unit spiral winding.
Preferably, cross rib is arranged in lobe, with cross rib center vertical face as interface, winding is single for winding unit
First both sides inside cavity is provided with hyphen rib, and after the docking of winding unit spiral winding, two corresponding hyphen ribs are connected into cross rib
Long cross rib.
Preferably, cross rib is arranged in lobe, the both sides of winding unit are cavity, the outer side edges and upper side edge of cavity
Straight flange is, two straight flanges are perpendicular, two outer side edges docking after winding unit spiral winding, the upper side edge external helicoid winding of docking
Hot melting cohesion has hollow cap, and a perpendicular muscle is provided with cap, and the outer side edges that perpendicular muscle is docked with two collinearly and form projection
The vertical rib of portion's cross rib, cap profile are matched with two profiles for docking cavity after winding unit spiral winding.
The invention has the beneficial effects as follows：Lobe improves the position of test ring stiffness as tubing, and between lobe
Outer muscle Guan Zewei tubing embodies the position of actual ring stiffness, after the position between two adjacent projections increases outer muscle pipe, so as to carry
The high actual ring stiffness of drain pipe.
