Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of bellows, more specifically, the utility model relates to a PE-HM reinforced perforated bellows. BACKGROUND

[0002] In the fields of modern municipal engineering, water conservancy engineering and underground comprehensive pipe gallery construction, bellows are widely used in pipeline systems such as drainage, sewage and cable protection due to their good flexibility, corrosion resistance and convenient construction. With the continuous advancement of infrastructure construction, the engineering environment is becoming increasingly complex, and higher requirements are placed on the mechanical properties of bellows, especially in terms of resisting complex external loads and tensile deformation.

[0003] At present, the common bellows on the market mostly adopt single-layer or simple reinforced structures. Although some products have certain compression resistance, they lack compression resistance and deformation resistance under complex conditions such as uneven settlement and large lateral pressure, which can cause pipe deformation, rupture and other problems, affecting the normal operation and service life of the pipeline system. In the process of external environment change or long-term use, structure loosening and support failure may occur, which cannot effectively disperse external pressure, leading to local stress concentration. Some bellows have poor tensile resistance due to structural limitations and difficulty in releasing bending modulus when subjected to tensile force, which cannot meet the requirements of special engineering scenarios for the mechanical properties of pipe materials.
