Testing of Drainage Materials for Railway EngineeringHow to apply for a report? What items need to be tested? We will conduct testing and evaluation in strict accordance with the standards. We can also provide personalized testing plans and reports according to your needs.

During railway construction, tunnel leakage is one of the common diseases, especially problems such as over excavation of excavation sections, poor support quality, substandard monitoring and measurement work, and incomplete waterproof and drainage facilities, which easily lead to leakage problems in railway tunnels. If leakage occurs, it will not only affect the service life of railway engineering, but also affect the safety of railway operation, and even cause serious traffic accidents. Therefore, special attention should be paid to the selection of waterproof and drainage materials and construction. The testing scope of drainage pipes includes water supply and drainage pipes, PVC drainage pipes, concrete drainage pipes, buried drainage pipes, PE drainage pipes, PC food grade drainage pipes, building water and electricity drainage pipes, HDPE drainage pipes, CP drainage pipes, RCP drainage pipes, etc. Routine testing for drainage pipe testing items: corrosion resistance testing, smoothness testing, permeable area testing, longitudinal shrinkage testing, bending testing, ring stiffness testing, pressure resistance testing, etc. Strength testing: tensile strength testing, bending strength testing, compressive strength testing, compressive strength testing, shear strength testing, impact strength testing, elongation at break testing, etc. Aging tests: ozone aging test, ultraviolet aging test, salt spray aging test, hernia lamp aging test, carbon arc lamp aging test, halogen lamp aging test, life assessment, etc. Thermal performance: heat resistance testing, cold resistance testing, low-temperature performance testing, brittle transition temperature testing, etc. Combustion performance: vertical combustion detection, horizontal combustion detection, smoke density detection, oxygen index detection, thermal stability detection, etc. Liquid resistance performance: water resistance test, acid resistance test, alkali resistance test, oil resistance test, chemical reagent resistance test, solvent resistance test, etc
