Abstract

The invention provides a construction method of a ground main body structure of a high-speed rail station, and relates to the technical field of main body structure construction of constructional engineering. The construction method comprises the seven steps of first-layer structure layer construction, second-layer structure layer construction, sandwich structure layer construction, top-layer frame structure construction, roof steel structure construction, secondary structure masonry construction and metal roof installation. According to the construction method, various quality problems, such as main body structure cracks, leakage and deflection changes, easily occurring in a normal use state of the ground main body structure of the high-speed rail station in the prior art are solved, the construction period is short, and the comprehensive manufacturing cost is low; according to the construction method, the construction speed can be increased, the labor intensity is relieved, the engineering quality is improved, and the engineering cost is reduced.

Description

technical field [0001] The invention relates to the technical field of main structure construction of construction engineering, in particular to a construction method of a ground main structure of a high-speed railway station. Background technique [0002] In just a few years, with a series of high-speed rail trains flying close to the ground, China has become the world's high-speed rail system with the most complete technology, the strongest integration capability, the longest operating mileage, the highest operating speed, and the largest scale under construction. s country. [0003] The construction volume of my country's high-speed rail stations has also increased significantly in recent years. The construction project of the high-speed railway station is large in size, difficult in construction, tight in construction period, high in quality standards and difficult in safety protection. In view of these characteristics and difficulties, the industry must carry out over...
