Device for enhancing rigidity of HDPE (high-density polyethylene) pipe ring

Technical Field

The utility model relates to a pipeline transportation field.

Background

The pipeline transportation has the advantages of large, continuous, rapid, economic, safe, reliable and stable transportation amount, less investment, less occupied area and low cost, and can realize automatic control. With the promotion of domestic water and soil environment treatment and comprehensive pipe gallery construction, the pipeline becomes an engineering construction hotspot, wherein the HDPE pipe (high-density polyethylene pipe) has the characteristics of small water flow resistance, high connection reliability, low-temperature impact resistance, stress cracking resistance, chemical corrosion resistance, aging resistance, good wear resistance and the like, and is widely applied to various engineering constructions. However, pipeline transportation is a typical linear engineering, and the problem that the peripheral pressure of a part of a pipe section is higher, so that the deformation of an HDPE pipe reduces the whole pipeline transportation efficiency often occurs.

If the HDPE pipe in the section with larger peripheral pressure is replaced by other pipelines with stronger rigidity, the water flow resistance along the pipelines is inconsistent, the water flow resistance of the replacement section is larger, and the conveying efficiency of the whole pipeline is also reduced. If a concrete pipeline or other supporting modes are adopted to protect a section with larger peripheral pressure, the defects of high construction cost and low efficiency exist, and the method is not suitable for popularization.

SUMMERY OF THE UTILITY MODEL

The utility model aims to protect the HDPE pipe of high peripheral pressure section, avoid it to receive peripheral pressure effect to warp down.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a device of reinforcing HDPE pipe ring rigidity, its includes that a plurality of cover is in the outer protection tube of the HDPE pipe section that needs to protect, cup joints a plurality of annular I-steel props that support between HDPE pipe section that needs to protect and outer protection tube and establishes ties annular I-steel and prop fixed many reinforcing bars together and make adjacent annular I-steel prop keep the same interval.

Specifically, the annular I-shaped steel support is provided with an inner ring and an outer ring, the inner ring is sleeved outside the HDPE pipe section to be protected, the outer ring is sleeved inside the outer layer protection pipe, an annular connecting structure is connected between the inner ring and the outer ring, and the cross section of the annular I-shaped steel support is I-shaped.

As the preferred mode, the contact position welded fastening of annular I-steel props and outer protection tube, reinforcing bar.

Preferably, a plurality of axial through holes are formed in the annular end face of the annular connecting structure of the annular I-shaped steel support at equal angles around the circle center, and reinforcing steel bars penetrate through the axial through holes and are welded and fixed to the annular I-shaped steel support.

Preferably, there are four of said axial through holes.

Preferably, the outer protection tube is an HDPE tube.

The utility model discloses a set up annular I-steel and prop, reinforcing bar and outer protection tube, form ring rigidity reinforcing skeleton in the HDPE pipeline section outside that needs the protection, form sufficient rigidity protection to the HDPE pipe of high peripheral pressure section, constitute peripheral pressure's inoxidizing coating. The utility model discloses simple structure, the material component is few, and the efficiency of construction is high, and maneuverability is strong, can be according to the nimble adjustment of size of peripheral pressure, is fit for the HDPE pipeline protection under various diameters, the various peripheral pressure condition, and the efficiency of construction is high, and is with low costs, especially adapted popularization and application.
