Pipe gallery, the steel strand wires hydraulic expanding then carried out between prefabricated pipe gallery are drawn, and it is seamless right between prefabricated pipe gallery to realize
It connects；
(2) leading device is put down, is opened truss to mounted prefabricated pipe gallery using driving mechanism, so that truss
Front end is fallen at the top of prefabricated pipe gallery to be assembled, and a prefabricated pipe gallery to be assembled is at least reserved in truss bottom；
(3) crane trolley position is adjusted by hoist engine, by suspension hook of the sling hook at the top of the prefabricated pipe gallery of truss bottom
On, start hydraulic cylinder, entire truss is jacked up, is detached from ground so that prefabricated pipe gallery be sling；
(4) at this point, decentralization support correction crossbeam, falls within the weight of truss on support correction crossbeam, adjust the position of crane trolley
It sets, splices that it with mounted prefabricated pipe gallery, transfer prefabricated pipe gallery, be then detached from hoist cable and suspension hook, and
The steel strand wires hydraulic expanding carried out between prefabricated pipe gallery is drawn, and realizes seamless interfacing；
(5) after lifting the prefabricated pipe gallery below end joist, support correction crossbeam is packed up, hydraulic cylinder is fallen after rise, utilizes driving
Mechanism driving truss and leading device move forward, prefabricated comprehensive below truss hoisting after the same method behind in-position
It closes piping lane itself and the prefabricated pipe gallery seamless interfacing being installed after being all installed, are lifted leading device, removed
Truss out.
7. the prefabricated pipe gallery of a kind of self-driving type Urban Underground according to claim 6 is laid with the construction method of hoisting machine,
It is characterized in that, when truss and prefabricated pipe gallery placement angle are there are when gap, by adjusting tensioner adjustment screw in hanging beam
On position adjust the position of hoist cable.
8. the prefabricated pipe gallery of a kind of self-driving type Urban Underground according to claim 6 is laid with the construction method of hoisting machine,
It is characterized in that, tensing hoist cable after hoist cable hooks prefabricated pipe gallery by adjusting tensioner adjustment screw, prevent hoist cable de-
From prefabricated pipe gallery.
9. the prefabricated pipe gallery of a kind of self-driving type Urban Underground according to claim 6 is laid with the construction method of hoisting machine,
It is characterized in that, when truss and prefabricated pipe gallery form larger deviation post, by adjusting truss in support correction crossbeam
On position adjust the position of hoist cable.
