Abstract
The invention discloses a tunnel steel arch installation method. The method comprises the steps that an operation rack is set up, and a lifting rack and a moving track are installed on an excavation trolley; a lifting trolley is installed; steel arches are lifted, wherein the lifting trolley is used for lifting steel arch components onto the operation rack; the steel arches are connected on the operation rack; the steel arches are installed, wherein the lifting rack is used for installing the steel arches. The tunnel steel arch installation method has the advantages that the installation speed of the tunnel steel arches is increased, waste of labor of workers is reduced, safety and reliability are achieved, and the actual installation cost of the tunnel steel arches is lowered.
Description
Technical field
The present invention relates to a kind of tunnel steel arch frame mounting method.
Background technology
In construction of tunnel, various Modelling of Tunnel Excavation in Soft Rock uses steel arch-shelf as the one of preliminary bracing in a large number, wherein shaped steel arch application is more frequent, steel arch-shelf conventional at present mainly comprises reinforcing bar grid bow member and shaped steel arch, its concrete work progress is: in tunnel portal steel beam column factory according to each component of country rock design size processing type steel arch-shelf residing for tunnel, after tunnel excavation, loader is utilized to have bad luck to face place by manufactured Steel section member, adopt digging machine to coordinate and manually carry out in-site installation, this constructure scheme Problems existing is mainly in installation, need digging machine to coordinate during installation manually to install, it is artificial that at substantial vertically had bad luck by shaped steel, and heavy mechanical equipment is not because having working space, use not smooth.Tunnel steel arch frame is installed and is adopted hand fit digging machine, loader is installed, and during installation, not only causes mounting cost higher, and big machinery appropriate to the occasionly causes machine security accident with artificial construction simultaneously.And in city, workman's labor wage is generally higher, tunnel steel arch frame is installed and is adopted artificial installation to cause expenses of labour higher, added cost, and because artificial steel arch-shelf efficiency of installing is too low, overlong time, causes tunnel can not carry out steel arch-shelf installation and lower step construction of shotcrete in time after excavation.
Summary of the invention
Its object of the present invention is just to provide a kind of tunnel steel arch frame mounting method, has increase tunnel steel arch frame installation rate, minimizing workman manually wastes, safe and reliable feature, and reduce tunnel steel arch frame installation actual cost.
Realize above-mentioned purpose and the technical scheme taked, comprise step,
1) setting of operation platform, is mounted on excavation chassis by lifting rack and moving track;
2) lifting dolly is installed;
3) steel arch-shelf lifting, utilizes lifting dolly to winch on operation platform by steel arch-shelf component;
4) steel arch-shelf connects, and operation platform connects steel arch-shelf;
5) steel arch-shelf is installed, and utilizes lifting rack, carries out steel arch-shelf installation.
Compared with prior art the present invention has the following advantages.
There is increase tunnel steel arch frame installation rate, minimizing workman manually wastes, safe and reliable feature, and reduce tunnel steel arch frame installation actual cost.
Detailed description of the invention
Comprise step,
1) setting of operation platform, is mounted on excavation chassis by lifting rack and moving track;
