Abstract
A method and installation for constructing highways. The object is to extend operational capabilities of a mobile installation for constructing a highway in a space-limited environment without reducing the traffic intensity and construct the highway above an existing main traffic motorway. The method includes constructing the highway in the form of an elevated road passing at least by the part thereof over the existing motorway and also includes a portal type mobile self-propelled installation. The moveable legs of the installation are disposed within the land allocation of the existing motorway.
Claims46
A method of constructing an expressway in a form of an elevated road whose length extends at least partly above an existing motorway, said method comprising the steps of:
- forming a foundation portion for load-bearing supports;
- erecting the load-bearing supports on the foundation portion;
- placing girders on the load-bearing supports and forming a span structure;
- erecting the load-bearing supports on the foundation portion when arranging at least a portion of a technological equipment for construction of the expressway on an upper load-bearing working surface of a gantry-type mobile installation, which installation is self-propelled and consists of sections disposed in-series along its length;
- disposing mobile supports of said installation within an allocated land lot of the existing motorway;
- mounting the girders on the load-bearing supports with at least one hoisting mechanism used as the technological equipment;
- disposing said at least one hoisting mechanism of a mobile crane at least on one section of the gantry-type mobile installation, and a height of clearance under said installation, in its operation position, being sufficient for allowing traffic on the existing motorway;
- carrying out at least a part of the construction of the expressway such that traffic on the existing road may proceed;
- aligning a longitudinal axis of the elevated road, at least along a portion of its length, at an angle to a longitudinal axis of the existing motorway;
- mounting the span structure by laying pre-assembled sections of the span structure by the hoisting mechanism positioned on an already constructed portion of the elevated road;
- forming sections of the span structure by pulling over said pre-assembled sections;
- and
- using the upper load-bearing working surface of at least one section of the gantry-type mobile installation as an intermediate support for said pre-assembled sections.
