Description

TECHNICAL FIELD

[0001] The present application relates to the field of railway track laying equipment, in particular to a joint cutting and cleaning integrated system for slab-type ballastless track bed. BACKGROUND

[0002] In railway track laying, CRTS III type slab-type ballastless track is an important innovation in Chinese high-speed railway track technology, with advantages of high smoothness, high stability and low maintenance cost. It mainly reflects in the following aspects: track structure design: CRTS III type track adopts the combination of prefabricated track slab and cast-in-place concrete base, the track slab is installed on the concrete base through precise positioning, forming an integral track structure, which effectively reduces track deformation and settlement, improves the stability and durability of the track; construction technology: the laying of CRTS III type track adopts advanced construction technology, including prefabrication, transportation, laying and fine adjustment of track slab, etc. The track slab is prefabricated in the factory to ensure the dimensional accuracy and surface flatness. High-precision measuring equipment is used for positioning and adjustment during on-site laying to ensure the accuracy of track geometry; material technology: CRTS III type track uses high-performance concrete and steel reinforcement materials to improve the compressive strength and fatigue resistance of the track. At the same time, elastic pads are used between the track slab and the base to effectively absorb the vibration and impact during train operation, improving the ride comfort; intelligent construction: during the laying process, intelligent construction technology is introduced, such as automatic measurement system, robot fine adjustment equipment, etc., which improves the construction efficiency and accuracy and reduces human error.

[0003] The popularization and application of CRTS III type slab-type ballastless track marks that Chinese high-speed railway track technology has reached an international leading level, providing a solid guarantee for the safe, comfortable and efficient operation of high-speed rail. The joint cutting technology of CRTS III type slab-type ballastless track bed is a key link in the construction of high-speed railway track, and the joint cutting process requires high precision and efficiency. Diamond saw blades are usually used for cutting to ensure that the joint width, depth and flatness meet the design requirements. The cutting time is selected after the initial setting and before the final setting of the concrete to ensure the quality of the joint and avoid damage to the concrete structure. After the cutting is completed, the joint needs to be cleaned and filled, usually with elastic sealing materials to prevent water and debris from entering the joint and affecting the durability and stability of the track structure. The joint cutting of CRTS III type slab-type ballastless track bed can improve the safety and service life of the track, providing an important guarantee for the smooth operation of high-speed rail.

[0004] The slotting width of the CRTS III type slab-type ballastless track bed is 20 mm, and the slotting depth is 20-30 mm. In the existing slab-type ballastless track bed joint cutting construction, the construction personnel generally cut slots along the preset cutting line by means of cutting equipment, and manually clean and subsequently apply interface agent and glue to the expansion joint. However, when the construction personnel cut joints by hand or push the joint cutting equipment, the slotting width, slotting depth and flatness are generally grasped by the construction personnel themselves according to their own feelings, which may lead to difficulty in guaranteeing the width, depth and flatness of the expansion joint, reduces the safety and service life of the track, and the dust at the expansion joint needs to be manually cleaned subsequently.
