Such scheme is preferred, and the width d of described enhancing steel rib is 8～100mm.
Preferably, in order to further enhance the comprcssive strength of drain pipe, and further protection strengthens steel rib by the corrosion of sewage to such scheme, and described recombiner unit is with and is strengthened steel rib made by steel plastic compount is one-body molded by outer strip, interior strip, connection.
Such scheme is preferred, in order to improve the hot strength of recombiner unit junction, extends the service life of drain pipe, and the adhesion width D between adjacent recombiner unit is 40～300mm.
Such scheme is preferred, and the thickness of described enhancing steel rib is 0.8～3mm.
Such scheme is preferred, the hot strength of the recombiner unit junction in order to improve further, and adjacent recombiner unit is resin dedicated bonding by polyethylene.
Another implementation of the present utility model is as follows:
Described tube wall includes outer strip, interior strip, a plurality of connection band, strengthens steel rib, and these connect and spaced are arranged between outer strip and interior strip, and described enhancing steel rib is then embedded in connection band.
Such scheme is preferred, and the cross section of tube wall is rectangle, and enhancing steel rib is perpendicular to outer strip and interior strip.
Such scheme is preferred, and described tube wall is made up by steel plastic compount is one-body molded of outer strip, interior strip, connection band and enhancing steel rib.
Compared with prior art, enhancing steel rib is embedded in connection band by this utility model completely, avoid strengthening steel rib to contact with air and water, enhancing steel rib is made to be not subjected to corrosion, and strengthen steel rib will not be subjected to displacement, its good stability, and it is all vertical with outer strip and interior strip to strengthen steel rib, also enhances drainage pipeline ring stiffness；Additionally the bond area between recombiner unit is big, and adhesive property is stable, also improves the hot strength of abutting edge, extends the service life of drain pipe.

Detailed description of the invention
Embodiment 1
This utility model is that a kind of polyethylene steel rib strengthens two flat walls drain pipe, as it is shown in figure 1, include tube wall 1, the inside and outside wall of tube wall 1 is planomural.Described tube wall 1 is mainly made up of spiral winding melting adhered multiple recombiner units 2.Described recombiner unit 2 includes outer strip 3, interior strip 4, at least 1 connects band 5, strengthen steel rib 6, these connect band 5 and are arranged between outer strip 3 and interior strip 4 at certain intervals, except the connection band 5 at both ends, all it is embedded with one in other connection band 5 and strengthens steel rib 6, ring stiffness in order to improve drain pipe is high, and strengthen steel rib 6 and be embedded in connection band 5 completely, it is to avoid air and the corrosion of water, increase the service life.Described outer strip 3, interior strip 4 and connect band 5 and be polythene material.
The cross section of described recombiner unit 2 is rectangle, as in figure 2 it is shown, described connection band 5 is each perpendicular to outer strip 3 and interior strip 4, and in order to further enhance the ring stiffness of drain pipe, strengthens steel rib 6 and is also perpendicularly to outer strip 3 and interior strip 4.Additionally described enhancing steel rib 6 is galvanized steel strip.
Described enhancing steel rib 6 is with to be connected band 5 contour, and its width is then less than connecting the width with 5, as shown in Figure 2, width called after d, the d value strengthening steel rib 6 is 8～100mm, and the thickness strengthening steel rib 6 is 0.8～3mm, so, strengthen steel rib 6 to be embedded in completely in polythene material.
