Straddle-type monorail bearing system and construction method thereof

Abstract

The invention discloses a straddle-type monorail bearing system and a construction method thereof. The monorail bearing system comprises a roadbed body, a foundation bed bottom layer laid on the roadbed body, a foundation bed top layer laid on the foundation bed bottom layer, piles buried in the roadbed body and the foundation bed bottom layer, and a capping beam arranged at the top ends of the piles. Track beams are installed on the capping beam. The straddle-type monorail bearing system and the construction method thereof have the beneficial effects that the monorail bearing system combining the roadbed body and the piles is adopted, and the supporting function of the roadbed body among the piles is fully used so that the stress function of a roadbed structure can be improved; compared with existing overhead track beams, while the span of single-line track beams is enlarged, the usage amount of the overhead track beams, overhead structure bridge piers and base materials is effectively reduced; and the structure stress is improved, investment is reduced, and the monorail bearing system has remarkable social benefits and economic benefits.

Description

technical field [0001] The invention relates to a straddling monorail support system and a construction method thereof, belonging to the technical field of transportation. Background technique [0002] With the population flow and economic development, my country's urban traffic congestion is becoming more and more serious, and problems such as single traffic structure and great impact on the environment are becoming more and more prominent. To solve these traffic problems fundamentally, the existing traffic structure must be adjusted. As a medium-capacity straddle monorail transportation, it has the advantages of strong adaptability, low noise, small turning radius, and strong climbing ability. It is a transportation form that meets the needs of cities in our country and has certain development prospects. The form of monorail supporting rail is usually elevated, which has the advantages of small footprint, full use of urban space, and good visual effects. However, the span ...

AI Technical Summary

Problems solved by technology

The form of monorail supporting rail is usually elevated, which has the advantages of small footprint, full use of urban space, and good visual effects. However, the span of the track girder between the elevateds is small, the number of foundations and piers is large, the engineering volume is large, and the cost is high. , so it is necessary to make technical improvements
