Ji reasonability and technical elements advantage and used, about 10 tons of the quality of shield, quality is very heavy, and traditional shield passes through vertical shaft
It is placed on pedestal, because shield quality is very heavy, pedestal can be caused to sink, shield is impacted, cannot ensure shield at work
Structure whether keep level, cause a departure axial-movement, pedestal poor rigidity, stability is not high, without stronger enabling capabilities.
The appearance that a kind of subway tunnel shield originates pedestal improves the rigidity and stability of shield launching pedestal, but passes
In place of the shield launching pedestal Shortcomings in system stage, pedestal is caused to sink for example, stability is not high, off-axis motion.
Utility model content
The purpose of this utility model is that providing a kind of subway tunnel shield originates pedestal, steady in conventional art to solve
It is qualitative it is not high cause pedestal to sink, off-axis move the problem of.
To achieve the above object, the utility model provides following technical scheme：A kind of subway tunnel shield originates pedestal, bag
Base, support frame, the first track and the second track are included, the base top is provided with vertical supporting bar, the vertical supporting bar
Top is provided with anti-sinker, and anti-sinker and vertical supporting bar bolt connection, is provided with inclined support bar on the left of the anti-sinker, institute
State and support frame is provided with inclined support bar, support frame as described above top is fixedly installed casing, and the casing passes through connecting rod and the
One track connects, and first rail inferior portion is provided with base crossbeam, and the base crossbeam right-hand member is provided with the second track, described
Negative endless tube piece is provided with base, the both sides of the base are provided with level meter.
Preferably, the bottom width of the base is 50cm.
Preferably, the base and vertical supporting bar bolt connection.
Preferably, the connecting rod and support frame threaded connection.
Preferably, the level meter is connected with chute of base.
Compared with prior art, the beneficial effects of the utility model are：The utility model is anti-in being internally provided with for base
Sinker, it can prevent pedestal from, than sinking during more loose work, causing shield not work, being provided with level meter can survey in soil property
Whether horizontal measure shield launching pedestal, accurately positioned to originating pedestal, strict elevation control and central axis, shield
Axis can be more slightly higher 10-20mm than the axis of design, so shield will not be impacted, support bar and inclined support bar have
Very strong enabling capabilities, stability is strong, pedestal is had enough rigidity and intensity, and casing is originating pedestal both ends, preventing from beginning
Hair pedestal is moved.
