Abstract

The invention belongs to the technical field of shield construction, and relates to a gantry crane combined beam device and an installation method. Bailey trusses are taken as a beam body, 609 mm steel supports and I45 steel are taken as beam columns to be connected with an existing concrete structure, and members such as angle steel and the like are transversely fixed with retaining structures toenhance the overall stability of the beam body. In order to ensure that tracks are uniformly transferred to the Bailey trusses, I28 I-steel at spacing of 50 cm are used as distribution beams. The whole beam body is composed of steel structures. The bailey trusses are combined in advance before installation. Other members are blanked in position in advance according to the existing structural dimension. After a shield machine is lowered into the well, installation can be completed in 1-2 days by a crane. The device is convenient, fast and safe, does not affect normal tunneling of the shield machine, enables a gantry crane to be put into use in time, and ensures construction efficiency.

Description

Technical field:

[0001] The invention belongs to the technical field of shield construction, and relates to a gantry crane combined beam device and an installation method, which are used in the installation and construction project of the shield gantry crane. When there is no concrete support beam at the enlarged end of the hoisting shaft or the support beam is blocked due to the influence of the shield hoisting After dismantling, two simple-supported track beams need to be added to ensure the normal movement of the gantry crane at the enlarged end. Background technique:

[0002] During subway shield construction, it is necessary to reserve a shield hoisting port near the tunnel in the station structure for the hoisting of materials and equipment such as shield machines and segments. Due to the large size of the shield machine, the structure at the hoisting shaft needs to be enlarged. About 3m. After the shield machine is hoisted, it is necessary to install a 25T gantry cran...
