Description
Technical Field
The invention relates to rail transit, in particular to an assembly type ballast bed structure capable of reserving vibration attenuation and adjusting height.
Background
In the early years, the urban building density in China is low, the number of sections with vibration reduction requirements in planning rail transit lines is relatively small, and non-vibration reduction rail structures such as common integral ballast beds and the like are adopted in a plurality of sections. However, with the continuous development of cities in China, under the large background of shortage and efficient utilization of land resources, the development of rail property industry becomes an important development direction of real estate industry. Therefore, the situation that a house or a commercial building is built near an existing line inevitably exists, so that a plurality of common integral road beds built in existing subways cannot meet the new vibration reduction requirement of the surrounding environment. Secondly, a large number of soft soil foundations exist in many cities in China, and after the subway is operated by traffic, the line can be continuously settled, so that the state of the line is deteriorated, and the driving safety is endangered. In addition, the problems of short period and heavy task exist in the current urban rail transit construction, and in order to improve the construction efficiency and quality of the rail engineering construction, an assembly type idea needs to be introduced into the design of the ballast bed.
Once the traditional common integral ballast bed is poured, the traditional common integral ballast bed cannot be upgraded and reformed into a vibration reduction ballast bed, so that the increasingly growing vibration reduction requirement on the periphery of a line is difficult to meet, and the complaints of residents along the line about subway vibration disturbance are gradually increased after the line is opened and operated for years; secondly, in the section with complex geological structure and large foundation settlement, the height of the traditional common integral ballast bed cannot be adjusted, the elevation of the steel rail can be adjusted in a limited way only through a fastener system between the ballast bed and the steel rail, the adjustment amount is small, and the line elevation error caused by the foundation settlement is difficult to eliminate, so that the line elevation and the line type gradually deviate from the original design value, and the safety and the stability of the train operation are influenced. In addition, the traditional common integral ballast bed adopts the construction process of current casting, and has the problems of long construction period, difficulty in controlling ballast bed quality, difficulty in repairing damaged ballast bed and the like.
Disclosure of Invention
The invention aims to solve the technical problem of providing an assembly type ballast bed which can reserve vibration reduction and can adjust the height so as to effectively realize the upgrading of the vibration reduction function of the ballast bed and the adjustment of the structural height, and has the advantages of high transformation and adjustment speed, stable quality and favorable reduction of the construction cost.
The technical scheme adopted by the invention for solving the technical problems is as follows:
the invention relates to an assembly type ballast bed capable of reserving vibration attenuation and adjusting height, which comprises a prefabricated track plate and a track foundation and is characterized in that: the prefabricated track slab is internally provided with cap-shaped components at intervals transversely and longitudinally along the slab surface, and the lower ends of the cap-shaped components are communicated with the bottom surface of the prefabricated track slab; the cap-shaped member is internally provided with a support, a support heightening gasket is arranged between the lower end of each support and the top surface of the track foundation, a reserved gap is formed between the bottom surface of the prefabricated track plate and the top surface of the track foundation, the height of the track structure is adjusted by replacing the support heightening gaskets with different thicknesses, and the load on the plate is uniformly transmitted to the track foundation through the cap-shaped member, the supports and the support heightening gaskets; the prefabricated track slab is characterized in that limiting grooves are formed in the longitudinal two ends of the prefabricated track slab, limiting devices fixedly connected with the track foundation are arranged in the limiting grooves, and the limiting devices act on the side walls of the limiting grooves to restrain the transverse displacement and the longitudinal displacement of the prefabricated track slab.
The beneficial effects of the invention are mainly reflected in the following aspects:
1. the upgrading of the vibration reduction function of the ballast bed can be effectively realized. Once the construction of the existing common ballast bed is finished, the vibration damping performance of the common ballast bed cannot be adjusted, and the common ballast bed can be upgraded into a high-grade vibration damping ballast bed with the vibration damping effect of 10-15 dB or a special vibration damping ballast bed with the vibration damping effect of more than 15dB by replacing different types of supports;
2. the height of the ballast bed structure can be effectively adjusted. The height of the conventional common track bed can not be adjusted, and the height of the track bed with the thickness of minus 10 to plus 20mm can be adjusted by replacing height-adjusting gaskets with different thicknesses and quantities below the support;
3. the upgrading of the vibration reduction function of the ballast bed and the adjustment of the height of the ballast bed structure can be realized quickly. The support in the invention adopts a miniaturized design, and a jack jacking operation space is reserved between the precast slab and the base, so that the support and the heightening gasket can be replaced in a normal line maintenance skylight, and the line operation is not influenced;
4. and the complete assembly design of the track bed is realized. The track bed plate, the limiting device, the support, the steel rail and the fastener are completely prefabricated or manufactured by a factory and are assembled on site, particularly the track bed plate and the limiting device do not need to be poured on site, and the construction efficiency and the construction quality are effectively improved;
5. the transformation of the existing line improves the efficiency and saves the investment. If the traditional common ballast bed needs to be transformed and upgraded, the existing concrete structure needs to be chiseled, and the limit structure is poured again after a new ballast bed plate is replaced and paved, so that the construction difficulty is high, and the cost is high. The invention can realize the upgrading of the vibration damping function and the adjustment of the structure height only by replacing different types of supports and heightening gaskets with different thicknesses, and the limiting device can be repeatedly used, thereby greatly reducing the construction cost of the reconstruction and upgrading of the existing line.

The height-adjusting gaskets 31 with different thicknesses and numbers can be selected according to different height-adjusting requirements, so that the height adjustment of the track bed of-10 to +30mm is realized.
Referring to fig. 7 to 9, the position limiting device 40 includes an outer housing 41, a top cover plate 42, a support body 47, and a position limiting device height-adjusting shim plate 48. The outer wall of the outer shell 41 is tightly attached to the side wall of the limiting groove 22. The support body 47 is located inside the outer casing 41 and forms a close fit with the inner wall of the outer casing 41. The supporting body 47 and the outer shell 41 are located on the surface of the limiting device heightening base plate 48, and the limiting device heightening base plate 48 is matched with the support heightening gasket 31 to realize synchronous adjustment of the heights of the limiting device 40 and the support 30.
