CRTS II slab-type ballastless track mortar bonding quality detection equipment and method

Abstract

The invention relates to CRTS II slab-type ballastless track mortar bonding quality detection equipment. The CRTS II slab-type ballastless track mortar bonding quality detection equipment comprises amain machine and a detection vehicle; the main machine comprises a central processing unit, an ultrasonic emission control module, an ultrasonic receiving processing module, and a network communication module; the detection vehicle comprises a detection vehicle bottom plate, a detection vehicle left side plate, a detection vehicle right side plate, a wheel-type speedometer, a track wheel assembly,two hydraulic rods, two supports, and a plurality of high frequency focusing ultrasonic transmit-receive sensor sets. The CRTS II slab-type ballastless track mortar bonding quality detection equipment is capable of solving a technical problem in the prior art that relatively large limitation is caused by detection on mortar layer open joint and disengagement using tools such as feeler gauges andsteel rulers.

Description

technical field

[0001] The invention relates to the technical field of quality and safety detection during operation of CRTS II slabs on high-speed railways, in particular to a CRTS II slab ballastless track mortar bonding quality detection device and method. Background technique

[0002] At present, the mileage of high-speed railways put into operation in my country has exceeded 20,000 kilometers. By the end of 2016, the total mileage of the CRTS Ⅱ slab ballastless track slab main line was nearly 10,000 kilometers, accounting for more than 40% of the total mileage of high-speed railway ballastless track lines. . The effective bonding between the track slab and the mortar layer guarantees the limit of the track slab, supports and transmits the vertical load, coordinates the displacement and transmits the horizontal load, so the mortar layer is an important part of the CRTSⅡ slab ballastless track system. Under the action of external factors such as train impact load, tempera...
