Description

Technical Field

[0001] The present invention belongs to the field of vibration and noise control of rail transportation, and in particular relates to a high-grade combined rail vibration reduction system applied to the inner line of a vehicle depot. Background Art

[0002] With the rapid development of the TOD model for rail transit, the demand for vibration and noise reduction inside and outside vehicle depots is increasing. Currently, the vibration reduction solution for lines inside vehicle depots mostly uses a combination of cast-in-place column structures and high-grade vibration-damping fasteners. However, this structure has many problems, mainly including:

[0003] (1) High construction intensity and low operating efficiency. Cast-in-place structures require many steps, including rail installation, formwork support, steel bar tying, concrete pouring, and maintenance. They require many workers and tools, and the construction progress is slow.

[0004] (2) Poor construction accuracy and difficult quality control. Inspection pit columns are mostly constructed from top to bottom using the "track method". Due to the dense steel bars on the top of the columns, it is difficult to pour concrete, resulting in the upper surface of the concrete being poured loosely and having poor flatness. This has become a major problem that has not been cured for a long time and can even affect driving safety in severe cases.

[0005] (3) Poor adjustability and inconvenient maintenance and repair. As the operation time increases, when the line deviation exceeds the adjustment capacity of the fasteners, it is difficult to restore the line status. In addition, the traditional concrete columns and foundation structure are cast in one go. If the columns are damaged or cracked after operation, maintenance and repair are extremely inconvenient.

[0006] (4) High construction cost. The construction cost of the cast-in-place column structure + high-grade vibration-damping fastener combination is as high as several thousand yuan per linear meter. In addition, the vibration-damping fasteners require frequent maintenance, resulting in high maintenance costs, but the vibration reduction effect is relatively poor.

[0007] To this end, in view of the above-mentioned defects, the designers of the present invention have, after careful design, theoretical research and a large number of experiments, researched and designed a high-grade combined track vibration reduction system for use in the depot line to overcome the many defects of the current cast-in-place column structure + high-grade vibration reduction fasteners.

The connecting base plate 5 and the prefabricated frame sleeper 1 are fixed as a whole by the bolt 7, and a nut is screwed and fixed on the end of the bolt 7 passing through the through hole 52.

[0093] In a preferred embodiment, the through hole 52 is a waist-shaped hole, and a detachable and replaceable adjustment gasket 8 is provided in the waist-shaped hole. The waist shape in this application can be a running sleeve shape, or it can be simplified to an elliptical shape, which can meet the usage requirements in this application.

A round through hole is opened in the adjusting washer 8; the round through hole can just allow the upper part of the bolt 7 to pass through.

[0095] There are many types of adjusting washers 8, such as Figure 6 and Figure 13 As shown in , each type of adjusting washer 8 has the same external structure and dimensions, but the circular through-holes therein are positioned differently.

[0103] Step 1: Measure the track deviation. When it exceeds the adjustment range of the fastener, lift the prefabricated column 2 and the connecting base plate 5 to disengage the bolt 7 from the waist-shaped hole.

[0104] Step 2: Based on the track deviation, select the model of the adjusting washer 8, replace the new adjusting washer 8 into the waist-shaped hole, and then lower the prefabricated column 2 and the connecting base plate 5 so that the bolt 7 passes through the round hole in the new adjusting washer 8;

[0105] Preferably, the track settlement adjustment comprises the following steps:

[0106] Step 1: Measure the track settlement. When it exceeds the adjustment range of the fasteners, lift the prefabricated columns 2 and the connecting base plate 5.

[0107] Step 2: Select the number and thickness of the height-adjusting spacers 9 according to the amount of settlement, and embed the height-adjusting spacers 9 between the connecting base plate 5 and the prefabricated frame sleeper 1 .

[0108] Preferably, the method for lifting the prefabricated column 2 and the connecting base plate 5 includes: lifting the prefabricated column 2 and the connecting base plate 5 by a sling, and also includes jacking up the prefabricated column 2 and the connecting base plate 5 by rotating the stud adjusting bolt by screwing a wrench.

[0109] Specifically, if the hoist is able to enter the construction site, the hoist can be selected for lifting. If the lifting distance is large, it is preferred to lift with the hoist first, and then fine-tune the lifting / jacking height by rotating the double-headed adjustment bolt.

[0110] Further preferably, during the process of track height adjustment, when the track settles unevenly, mortar bags and self-compacting grouting materials can be added and used in conjunction with height adjustment spacers 9.

[0111] The present invention has been described above in conjunction with preferred embodiments, but these embodiments are merely exemplary and serve only as an illustrative example.
