Rail transit underground station track panel well with prestressed concrete beams

Abstract

The invention discloses a rail transit underground station track panel well with prestressed concrete beams. The rail transit underground station track panel well comprises retaining structures (7) which are arranged longitudinally and symmetrically along the track panel well and a prestressed concrete beam structure, wherein the prestressed concrete beam structure comprises prestressed concrete I-beams (1) disposed longitudinally along the track panel well and perpendicular to the inner side of the retaining structures (7) and supporting hidden beams (2) disposed horizontally along the track panel well and perpendicular to the prestressed concrete I-beams (1); and the prestressed concrete I-beams (1) comprise prestressed steel beams (102). According to the rail transit underground station track panel well, the prestressed structure is applied to the structural design of an underground station of rail transit, the prestressed concrete structural beams are arranged in the long side direction of the hole edge of the track panel well, and prestressed working wells and horizontal supports are separately arranged at the head ends and the tail ends of the prestressed concrete structural beams, so that the problems of structural stress and deformation of station enclosure and a main body during a rail panel are solved.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and more particularly relates to a rail well of an underground station of rail transit with prestressed concrete beams. Background technique [0002] In the process of rail transit construction, due to the requirements of track laying, some underground stations need to set up a track laying base, that is, reserve a 30m×5m rail well on the floor of the station, and lift the 25m long rail well from the ground through the rail well to the track-laying wagon above the station floor and transported to the track-laying face to take care of the track-laying work. [0003] According to the hoisting requirements of the rail row, horizontal support members cannot be installed within the range of the station rail row well, so as to ensure the normal hoisting operation of the rail row well, which puts forward higher requirements for the station structure design of the rail row well section. In view of ...

AI Technical Summary

Problems solved by technology

[0005] In view of the above defects or improvement needs of the prior art, the present invention provides a rail transit underground station rail well with prestressed concrete beams. The prestressed structure is applied to the structural design of the rail transit underground station. Prestressed concrete structural beams with a span of 30m are installed in the long side direction, and prestressed working wells and lateral supports are respectively installed at the first and last ends of the prestressed concrete structural beams. This method can avoid obstacles such as underground anchor cables, On the premise of expanding the enclosure structure and increasing the structural size, which leads to an increase in project investment, it solves the structural force and deformation problems of the station enclosure and the main body during the rail row
