Description
Technical field
Originally practical to be newly related to a kind of shield machine field, in particular to a kind of novel slurry shield machine.
Background technique
With the quickening of city process and the expansion of city size, people also increasingly propose the demand of public transport
Height, in order to solve Traffic Problems, currently, many big cities have been gradually formed based on subterranean railway traffic, a variety of
Rail traffic and the urban track traffic system deposited.With the reduction of Underground Space Resource, cause tunnel main construction method it
One shield-tunneling construction is commonly encountered various underground obstacles in tunneling process, pipeline, the foundation pile, underground company discarded such as underground
Continuous wall, boulder etc.；Geological conditions locating for shield also can be very diversified simultaneously, there is clay, sand, gravel, soft rock etc.
Geological conditions.For the case where there are barriers in front of the shield that encounters, there are two types of the main methods of disposal taken: from ground
Excavation removes barriers object, and the advantages of this method is relatively safe, while construction is simple, technical maturity, the disadvantage is that influencing model
Enclose big, construction period growth, it is also necessary to be reinforced on a large scale to the soil body；Another method is before being directly cut by shield machine
Square barrier, this method does not influence the construction period, and coverage, construction investment are smaller, the disadvantage is that the damage of shield cutter
Hurt it is larger, to the front soil body and earth's surface building be likely to generate compared with large disturbances.So a kind of novel slurry shield machine is needed,
Improve the problem of current shield-tunneling construction encounters in the process.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of novel slurry shield machines, can be crushed shield-tunneling construction

It is hinged, the cylinder barrel of the rotation drive cylinder is hinged with firm banking, described flexible drive cylinder one end and probing rack
Fixed part be connected, the other end with probing rack pars contractilis be connected；The probing bar is fixedly mounted on probing rack
Connect on pars contractilis and with pressurized reservoir, the pressurized reservoir for probing bar high pressure water flow is provided, when in tunneling process in front
When encountering barrier, cutterhead stops operating, and probing rack extends, and shield cutter is passed through, according to the camera shooting information collection of drill head
The information of device feedback rotates drilling machine by rotation drive cylinder, makes to drill bar alignment barrier, be generated using probing bar
High pressure water flow barrier-breaking.
The beneficial effects of the utility model are:
(1) by the device, the barrier that can be encountered in front of broken shield rapidly and accurately also can be broken to barrier
Surrounding soil afterwards carries out grouting and reinforcing, guarantees safe construction.
(2) artificial air pressure export is avoided to cut barrier bring risk and guarantee when shield cuts barrier, barrier
Object is hindered not move with cutter head of shield machine.
