Problems solved by technology

For the sake of safety, the vertical stiffness of a single plate end vibration isolator is usually greater than that of other single elastic vibration isolators set in the prefabricated short floating slab. Due to the influence of various errors such as the base construction error, the prefabricated short floating slab is jacked up and leveled, and the vibration isolation device at the end of the slab and the elastic vibration isolator are separately installed according to the theoretical design value in the traditional way. To set up the height-adjusting backing plate and height-adjusting gas

Example Embodiment

[0029] Example one

[0030] Taking each prefabricated short floating slab in the floating track bed as an example supported by four plate end vibration isolation devices and four built-in elastic vibration isolators as an example, the difference between the prefabricated short floating slab in the floating track bed of the present invention The operation process of the installation and leveling method is given specific instructions. To facilitate the understanding of the method of the present invention, the basic structure of the floating track bed involved is explained first. The typical structure of the floating track bed is figure 1 and figure 2 As shown, taking the prefabricated short floating plate 2 as an example, it is jointly supported by four plate-end vibration isolation devices 4 and four built-in elastic vibration isolators 8, separated from the surface of the foundation 6, and the elastic vibration isolators 8 are placed on Inside the coupling sleeve 5 fixedly arra...

Example Embodiment

[0063] Example two

[0064] Still taking the floating track bed described in the first embodiment as an example, each prefabricated short floating slab is jointly supported by four plate end vibration isolation devices and four built-in elastic vibration isolators, which is different from the first embodiment. In the installation and leveling method of the prefabricated short floating slab in the floating track bed of the present invention, when the prefabricated short floating slab is placed in step (1), follow the method in step (1) to sequentially place and adjust The plane position of a lot of prefabricated short floating boards constitutes at least one installation section, and then each prefabricated short floating board in the installation section is first lifted and leveled, second lifted and leveled and precisely lifted Leveling, so as to realize the installation and leveling of the prefabricated short floating board in the floating track bed.

[0065] In the method for i...

Example Embodiment

[0067] Example three

[0068] Still taking the floating track bed with the structure described in the first embodiment as an example, based on the technical principles of the first and second embodiments, the installation and leveling method of the prefabricated short floating plate in the floating track bed of the present invention can also be developed as follows: The specific operation process is as follows:

[0069] (1) According to the plane positions of the prefabricated short floating slab and the four plate end vibration isolation devices marked on the basis of the track bed, place the plate end vibration isolation devices at the predetermined positions, and then place the prefabricated prefabricated The short floating board is placed on the vibration isolation device at the end of the board using lifting and transportation equipment, the plane position of the prefabricated short floating board is adjusted, and the plane position of many prefabricated short floating boards ...

Abstract

The invention belongs to the field of track traffic, and relates to an installation and leveling method of a floating slab in a floating track bed, in particular to an installation and leveling method of a prefabricated short floating slab in the floating track bed. The installation and leveling method of the prefabricated short floating slab in the floating track bed is simple to operate. As proved by project trail laying, the prefabricated short floating slab does not need to be heightened or leveled repeatedly in the installation process, one time of heightening and leveling can be basically achieved, and the method is quite convenient and rapid to operate, overcomes the technical bottlenecks of existing operation methods, further improves construction speed, meets the requirements of construction cycles, and largely improves the technical applicability of a steel spring floating slab track bed, thereby enabling the prefabricated short floating slab to be quite wide in market application prospect.

Description

technical field [0001] The invention belongs to the field of rail transportation, and in particular relates to a method for installing and leveling a floating slab in a floating track bed, in particular to a method for installing and leveling a prefabricated short floating slab in a floating track bed. Background technique [0002] Vibration and noise are recognized as the most widely affected public hazards, and they are also a problem that needs to be solved urgently in the development of rail transit in recent years. Among the existing rail transit vibration and noise reduction technologies, the most successful practical application is the component floating technology, typically the floating ballast bed technology, which has high vibration isolation efficiency and stable working performance, which has become a consensus in the industry, such as patent No. It is a built-in floating ballast bed structure disclosed in Chinese patent ZL200410035441.1. However, the construct...
