Description

Technical Field

[0001] The utility model relates to the technical field of PE corrugated pipes, and more specifically, it relates to an HDPE inner rib reinforced polyethylene (PE) spiral corrugated pipe. Background Technique

[0002] The steel belt reinforced polyethylene (PE) spiral corrugated pipe uses high-density polyethylene (PE) as the matrix, and forms a waveform with a steel belt coated with an adhesive resin on the surface as the main support structure, and is wound and compounded with the polyethylene material into an integral double-wall spiral corrugated pipe.

[0003] The steel belt reinforced polyethylene (HDPE) spiral corrugated pipe for buried drainage is formed by pressing a continuous steel belt into an approximate ^-shaped spiral steel rib and winding it between the inner and outer layers of heat-melted polyethylene, combining the high rigidity and strength of steel with the flexibility, corrosion resistance and wear resistance of polyethylene.

[0004] At present, most of the spiral corrugated pipes for buried drainage are non-steel belt reinforced polyethylene (HDPE) spiral corrugated pipes. The reinforced polyethylene (HDPE) spiral corrugated pipes are prone to breakage and damage during actual use, and most of the damage is crushing damage, which is difficult to repair on site. The reinforced polyethylene (HDPE) spiral corrugated pipes are weak in anti-collision, anti-drop and anti-compression capabilities, and often have more crack openings starting from the fracture mouth during use. Content of the Utility Model

[0005] The purpose of the utility model is to provide an HDPE inner rib reinforced polyethylene (PE) spiral corrugated pipe, an enhanced polyethylene (PE) spiral corrugated pipe capable of resisting pipe orifice cracks.

[0007] The outer ribs between the spiral columns can effectively limit the cracking between the spiral columns, and the setting of the inner ribs can further limit the cracking along the seams of the spiral columns. The setting of the outer ribs can also strengthen the overall load-bearing situation, and the setting of the inner ribs can strengthen the toughness during impact, making the possibility of cracking or damage smaller.

[0008] The utility model is further arranged as: a plurality of outer ribs arranged at equal intervals are arranged on the outer wall of the pipe body.

[0009] The stress distribution can be made more uniform through the equal interval arrangement, and the anti-stress effect is also better.

[0010] The utility model is further configured as follows: the inner wall of the tube body is provided with a plurality of inner ribs arranged at equal intervals.

[0011] The internal ribs arranged at equal intervals can more effectively achieve load-bearing and shear resistance.

[0012] The utility model is further configured as follows: two spiral columns arranged side by side and spirally arranged are arranged on the outer wall of the tube body.

[0013] The spiral pitch can be changed by two spiral columns arranged side by side, and the axial spiral pitch between the spiral bellows is increased, so as to better achieve the stress resistance and shear resistance effects.

[0014] The utility model is further configured as follows: a through hole is provided at the axis position of the spiral column.

[0015] Through-holes through the helical studs can effectively reduce the weight of the material without causing stress damage.

[0016] The utility model is further configured as follows: an inner lining strip is arranged in the through hole.

[0017] The provision of the lining strip can ensure that a buffering effect is achieved when the spiral column is hit, and even if it is broken, it will not affect the inner wall of the tube body.

[0018] The utility model is further configured as follows: the cross section of the inner lining strip is a trident-shaped structure.

[0019] The impact buffering effect can be achieved by setting the tripod structure.

[0020] The utility model is further configured as follows: the cross section of the inner lining strip is a cross-shaped structure.

[0021] A better pressure-bearing structure can be achieved through the Pozidrivium.

[0022] In summary, the utility model has the following beneficial effects: the outer ribs between the spiral columns can effectively limit the cracking between the spiral columns, and the setting of the inner ribs can further limit the cracking along the seams of the spiral columns, and the setting of the outer ribs can also enhance the overall load-bearing condition, and the setting of the inner ribs can enhance the toughness during impact, making it less likely to crack or break.
