Abstract

The invention discloses a ballastless track bed plate elevation rapid inspection vehicle which comprises fixing wheels which are transversely stretched on two sides of a bed plate. A vehicle frame is arranged on the fixing wheels. A prism, a tilt angle sensor and four sonar sensors are arranged on the vehicle frame. The prism, the tilt angle sensor and the four sonar sensors are connected with a total station. The aim that an elevation error of the upper surface of the bed plate is rapidly measured is achieved. The ballastless track bed plate elevation rapid inspection vehicle has the functions of field measurement, calculation, display and storage and can rapidly carry out detection and evaluation in real time. A special quality control device and method is provided for practical construction of a ballastless track. Construction efficiency is improved. Construction cost is reduced. A construction technical level of the ballastless track is improved.

Description

technical field [0001] The invention relates to a vehicle for quickly detecting the elevation of a ballastless track base plate. Background technique [0002] The substructure of the ballastless track of the high-speed railway - the construction of the base plate is one of the most important links in the construction of the ballast bed. In the construction of ballastless track with CRTS Ⅱ slab structure, the quality control of the base plate construction has a great influence on the later CA mortar construction, especially the elevation control of the upper surface of the base plate, which seriously affects the thickness of the CA mortar layer. According to the design specifications, the thickness of the CA mortar layer is controlled between 2-4cm. Since the bottom surface of the track slab is an uneven surface, when the elevation of the base plate is skewed, the effective thickness of the CA mortar layer is often less than 2cm. This is the case in Beijing, Shanghai and Beij...
