[0057] In the second aspect, the present invention also provides a first embodiment of a ballastless track track bed slab construction method, the method includes the following steps:

[0058] Step S100 , forming a support layer 100 . Wherein, at least one first connecting hole is formed on the top surface of the supporting layer 100, and the pin connecting member 300 is fixedly connected in the first connecting hole.

[0059] In this step, when the supporting layer 100 is an invert section, it may be a common invert section or a prefabricated invert section of a tunnel. After the support layer 100 is formed, at least one first connection hole is formed on the top surface of the support layer 100 . For example, when the pin connector is a sleeve, the open end of the matching hole of the pin connector can be sealed by a sealing cover or a sealing plug. The sealing plug or sealing cap can be made of highly flexible rubber. And the sealing plug or the sealing cover can be deta...

Abstract

The invention discloses a ballastless track roadbed slab connecting structure and a construction method, and belongs to the technical field of railway construction. The ballastless track roadbed slab connecting structure comprises a supporting layer, a first connecting hole is arranged in the top surface of the supporting layer; a pin connecting part is arranged in the first connecting hole; a roadbed slab is arranged on the top surface of the supporting layer, and a second connecting hole is formed in the bottom surface of the roadbed slab; a pin is fixedly arranged in the second connecting hole, and a part of the pin protrudes out of the bottom surface to form a matching part; a matching part extends into the first connecting hole and is detachably connected with the pin connecting part. The construction speed of the pins in the roadbed slab is greatly increased.

Description

technical field [0001] The invention relates to the technical field of railway construction, in particular to a ballastless track bed slab connection structure and a construction method. Background technique [0002] Double-block ballastless track is a common form of railway track construction, which has the advantages of good track linearity, high durability and less maintenance. [0003] However, the construction efficiency of anchor pins for double-block ballastless track is relatively slow. Contents of the invention [0004] The main purpose of the present invention is to provide a ballastless track track bed slab connection structure and construction method, aiming to solve the technical problem of relatively slow construction efficiency of the anchor pins of the double-block ballastless track in the prior art. [0005] In order to achieve the above object, in the first aspect, a ballastless track bed slab connection structure proposed by the present invention includ...
