Novel precast slab assembled floating track bed

Abstract

The invention discloses a novel precast slab assembled floating track bed which comprises a plurality of floating track bed precast slabs and a plurality of connecting devices. The floating track bed precast slabs are laid in sequence back and forth. Every two adjacent floating track bed precast slabs are fixedly connected together through the connecting devices. The connecting devices are used for sequentially connecting the plurality of floating track bed precast slabs into a whole to form the assembled floating track bed. Each floating track bed precast slab comprises a precast slab main body, two rows of track bearing platforms, an outer sleeve unit, first sleeve sets, second sleeve sets and third sleeve sets. Two ends portions of the precast slab main body are respectively provided with a groove structure. The first sleeve sets are arranged in the precast slab main body. The second sleeve sets are arranged corner portions of two sides of the precast slab main body. The third sleeve sets are arranged at the track bearing platforms. The novel precast slab assembled floating track bed is fast in assembling and convenient to regulate, substantially decreases operation processes and the construction cycle and multiply improves construction efficiency. When the novel precast slab assembled floating track bed is used in complex areas, due to a replaceable structure, maintenance time is greatly reduced, maintenance cost is decreased, and construction quality and integrity of the floating track bed are guaranteed.

Description

technical field [0001] The invention relates to the field of rail transit, in particular to a floating ballast bed assembled from novel prefabricated panels suitable for complex sections. Background technique [0002] With the rapid development of society and science and technology, various cities have successively launched the construction of urban light rail and subway. In order to increase the construction speed and shorten the construction period, the floating track bed construction is often carried out by prefabricated slab assembly, which overcomes the constraints caused by on-site pouring. The constraints brought by unfavorable factors such as space can greatly improve the construction efficiency. During construction, multiple prefabricated slabs are assembled to form a floating ballast bed, and a side-mounted partition shared by the two adjacent prefabricated slabs is set. The vibration device is used to provide elastic support and control the settlement difference b...

Problems solved by technology

However, since the current splicing mainly relies on the hoisting equipment to place the prefabricated panels on the vibration isolation device under the panels, and then cooperates with the method of manual accurate position adjustment, when the hoisting equipment is placed with a large error, the manual prefabricated panels The adjustment of the prefabricated slab is time-consuming and laborious, and since the side-mounted vibration isolator is used to connect and damp the adjacent prefabricated slabs, it is necessary to repeatedly assemble the adjacent prefabricated slabs while adjusting the prefabricated slabs. Therefore, the speed of construction is restricted, a large amount of manpower and material resources are consumed, and the cost of construction is increased.
