Embodiment Construction

[0038] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0039] A trackless construction method for a lateral platform in a subway section, which is innovative in that it includes the following steps:

[0040] (1) Determination of the 4-point position of the center pile of the line corresponding to the platform steel beam and the lateral platform slab

[0041] a. Determine the starting point, the mileage of the starting point is the end mileage of the lateral platform in the construction drawing;

[0042] b. Calculate the mileage of each platform steel beam, and infer the mileage of the next point through the distance; the mileage of the platform steel beam at any point can be obtained by accumulating the distance, that is, the mileage of the next platform steel beam is the mileage of the previous platform steel beam plus the distance;

[0043] c. Calculate the point coordinates of the line center pile ...

Abstract

The invention relates to a trackless construction method for a lateral platform in a subway section, which is characterized in that it includes the following steps: (1), determining the position of the center pile point of the corresponding line of the platform steel beam and the lateral platform slab; (2), the platform steel beam Measurement and positioning of beams and lateral platform slabs; (3), assembly calculation of platform steel beams and lateral platform slabs; (4), installation and review of platform steel beams and lateral platform slabs. The invention determines the installation position, prefabricated size and radian of the platform steel beam and the lateral platform slab before laying the track, shortens the construction period, improves the construction efficiency, saves the construction cost, and solves the problem that the measurement and positioning of the lateral platform in the subway section depend on the track. The resulting delay in the construction period has filled the gap in the trackless construction technology of the lateral platform in the subway section in my country, and achieved good economic and social benefits.

Description

technical field [0001] The invention belongs to the field of subway construction, and relates to a construction method for a lateral platform in a subway section, in particular to a trackless construction method for a lateral platform in a subway section. Background technique [0002] At present, the construction of the lateral platform in the shield section of the subway adopts the method of laying the track first and then proceeding with the construction. The specific method is: lay the track in advance in the shield section, and then measure the installation height, length and radian of the platform steel beam according to the track , on the basis of these data, the prefabrication of platform steel beams and lateral platform slabs is carried out. The platform slabs of the lateral platforms are set on the platform steel beams. [0003] These traditional construction methods are time-consuming, and measurement and product ordering can only be carried out after the track is...
