Description

Enhancement mode HDPE double-wall corrugated pipe
Technical field
This utility model relates to corrugated tube, particularly to enhancement mode HDPE double-wall corrugated pipe.
Background technology
HDPE (High Density Polyethylene, high density polyethylene (HDPE)) double-wall corrugated pipe, is called for short PE Corrugated tube, a kind of novel light tubing with high density polyethylene (HDPE) as raw material, inner wall smooth is smooth, and outer wall is Trapezoidal or arcuate corrugation shape rib, is the tubing of hollow between inner and outer wall ripple.Have light weight, corrosion-resistant, Ageing-resistant, product strength is big, good bending property and the feature such as construction and installation are convenient, be widely used in industry and Civil outdoor drainage system, belongs to environment-friendly product.It has become the head of pipeline field " to mould Dai Gang " Select tubing, which overcome that the installation difficulty such as pipe of cement, earthenware, cast iron pipe are big, easy-to-rust, resistance to water-flow Greatly, the shortcoming that breed bacteria, life-span are short.
But in use, due to the uneven sink-float of soil, HDPE double-wall corrugated pipe can be caused punching Hit, once more than the anti-pressure ability of HDPE double-wall corrugated pipe, HDPE double-wall corrugated pipe can be caused necessarily The destruction of degree, affects the service life of HDPE double-wall corrugated pipe.It addition, existing HDPE double-walled ripple Stricture of vagina pipe there is also the problem that installation, connection inconvenience and junction easily leak.
Utility model content
The utility model proposes enhancement mode HDPE double-wall corrugated pipe, solve existing HDPE double-wall corrugated There is the defect that insufficient strength, connection inconvenience and junction easily leak in pipe.
The technical solution of the utility model is achieved in that
Increase type HDPE double-wall corrugated pipe, including tube body with to female connector, tube body wraps the most successively Including outward corrugated tube, skeleton back-up coat, heat-insulation layer and interior straight tube, tube body one end is public plug, and the other end is Mother takes the lead, and public plug is outside equipped with the first docking bulge loop, and mother takes the lead and is outside equipped with the second docking bulge loop;Docking Set includes the first upper half collar, the first lower half collar, the second upper half collar and the second lower half collar, on first The first groove coordinated with the first docking bulge loop, the second upper half are set on half collar and the first lower half ferrule end face The second groove coordinated with the second docking bulge loop, the first upper half set are set on the collar and the second lower half ferrule end face Ring and the first lower half collar are bolted, and the second upper half collar and the second lower half collar are bolted, The first upper half collar and the second upper half collar are bolted, and the first lower half collar and the second lower half collar lead to Cross bolt to connect.
Further, it is provided with sealing ring between described first docking bulge loop and described second docking bulge loop.
Further, described skeleton back-up coat is steel plate or steel mesh.
Further, described heat-insulation layer is asbestos gauge.
Further, the described first upper half collar, the first lower half collar, the second upper half collar and the second lower half set Being provided with docking projection and left and right docking projection up and down on ring, docking projection and left and right are docked on projection up and down It is provided with bolt hole.
The beneficial effects of the utility model: this utility model adds skeleton between outward corrugated tube and interior straight tube Back-up coat and heat-insulation layer, add intensity of the present utility model and heat-insulating property;As long as installing public affairs when connecting Plug inserts mother and takes the lead, and then puts female connector, spins bolt, convenient and simple for connection;Convex in the first docking Between ring and the second docking bulge loop, sealing ring, good seal performance are set.
Accompanying drawing explanation
