Shield machine receiving steel platform and installation method thereof

Abstract

A shield machine receiving steel platform and its installation method, including a column system standing on the foundation, an inter-column support system and a receiving module system, the column system includes a group of columns, and each column includes a base column that is sequentially centered and docked unit, at least one layer of extended column group and top support column unit, the base column unit is a conversion short column, the extension column group is composed of a conversion short column on the upper side and a long column on the lower side, and the top support column The unit is a short column at the top of the column, the inter-column support system includes a set of horizontal connecting beams, a set of inclined connecting beams and a set of inclined supporting beams, and the receiving module system includes a set of panel units. The receiving steel platform of the shield machine of the present invention adopts detachable connection, each unit component is prefabricated and processed in the factory, the utilization rate of the mechanical properties of the column system is improved, and the possibility of instability is reduced.

Description

technical field [0001] The invention belongs to underground engineering, in particular to a receiving steel platform of a shield machine and an installation method thereof. Background technique [0002] Shield machine is a kind of tunnel boring machine using shield method. With the development of urban rail transit, shield machine appears in more and more underground engineering construction. Shield receiving refers to a certain distance from the tunnel to the receiving well, usually about 100 meters until the shield machine falls on the receiving base in the receiving well. However, the receiving of the conventional shield machine needs to be carried out after the shield shaft bottom plate or the middle plate reinforced concrete structure of the underground project is constructed and the maintenance strength meets the requirements, and the receiving frame body is directly placed on the concrete structure and fixed for receiving. When the construction period is tight, and t...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a shield machine receiving steel platform and its installation method, to solve the problem that the existing steel column platform structure is inflexible in response to the receiving conditions, and the platform cannot be adjusted according to changes, which easily leads to the waste of steel It is also necessary to solve the technical problem that the shield machine will have a large bending moment on the steel column platform, which will easily lead to structural deformation and instability of the steel column platform
