Embodiment Construction

[0026] figure 1 The flow chart of an embodiment of a construction method for a CRTSⅢ slab ballastless track base plate of the present invention is shown, and the construction method includes the following steps:

[0027] S1: Construction preparation: complete the inspection and acceptance of the chiseling on the beam surface, organize materials and equipment to enter the site, measure the four corner points of the base plate and stake out, record the elevation of the stake out points, and use ink lines to pop up the corner points between the four corner points. Wire;

[0028] S2: Reinforcement installation: The reinforcement mesh is laid in two layers. First, the bottom layer of reinforcement mesh is laid according to the connection line of the corner points, and then the L-shaped connection reinforcement is installed in the connecting sleeve embedded in the beam surface. After completion, the top layer of reinforcement mesh is laid. It is supported and fixed by L-shaped conn...

Description

technical field [0001] The invention relates to a construction technology of a slab ballastless track, in particular to a construction method for a base plate of a CRTSⅢ slab ballastless track. Background technique [0002] The CRTS III slab ballastless track is composed of steel rails, elastic shoulder fasteners, prefabricated track slabs, self-compacting concrete filling layers, limit grooves, intermediate isolation layers (geotextiles) and reinforced concrete base plates, with stable performance and durability Good performance and long service life. The CRTSⅢ slab ballastless track base plate is used as the load-bearing layer and sliding layer between the track slab and the beam surface. The top surface elevation and flatness control requirements are high, and the accuracy is difficult to guarantee. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a CRTSⅢ type ba...
