The shield machine receiving platform is characterized in that after the tunnel construction of an upper tunnel in a top/bottom overlapped tunnel is completed, the shield machine receiving platform is fixedly arranged on a base plate of a station according to a certain quantity, the top plate is taken as a middle plate of the station for carrying the shield machine in the prior art, a tunnel portal can be broken down after the construction of the shield machine is completed, and the shield machine can be received regardless whether the middle plate of the station is constructed, so that the construction efficiency of the tunnel and the use efficiency of the shield machine are greatly improved.
Description
Technical field
The utility model has related to a kind of tunneling shield construction servicing unit, particularly a kind of shield machine receiving platform.
Background technology
Flourish along with the National urban urban rail transit construction, shield structure overlapping tunnel appears in the increasing subway work.On shield machine is finished, after the hole tunnel driving task, how to hang out, become a great problem in the overlapping tunnel construction from hanging out well head.
To receive be etc. that plate is finished in the station to the hole shield machine on traditional so far overlapping tunnel, and middle plate just can be abolished portal after reaching design strength, carries out shield machine and receives, and this method often causes construction delay, waste great human and material resources, have a strong impact on economic benefit.
The utility model content
Technical problem to be solved in the utility model provides a kind of shield machine receiving platform, carries out shield machine again after the plate construction finishes in need not to wait in the overlapping tunnel construction and receives, and effectively the reduction of erection time, improves efficiency of construction.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of shield machine receiving platform comprises column, girder, secondary beam and top board; Described column setting at least three rows four row all are fixed with bearing diagonal between the horizontal and vertical two adjacent columns; Described every row column top all is fixed with girder one; Described girder top be fixed with every row's column over against secondary beam; Described top board is fixed at time top surface of the beam.
Described column is a steel pipe, and described steel pipe bottom is fixed with mount pad, and the top is fixed with the sealing steel plate.
Described girder is an i iron, the sealing steel plate welding of described i iron bottom surface and column end face.
The corresponding secondary beam of described and every row column comprises two i iron that are set up in parallel, and described i iron is welded on the girder end face.
Adopt the beneficial effect that technique scheme produced: after the tunneling shield construction finishes on overlapping tunnel up and down, shield machine receiving platform disclosed in the utility model is fixedly mounted AT STATION on the base plate according to some, serve as the station plate that is used for carrying shield machine in the prior art with its top board, shield machine construction finishes and can abolish portal, carrying out shield machine receives, need not to wait and carry out the shield machine reception again after the plate construction finishes in the station, improve constructing tunnel efficient and shield machine service efficiency greatly.

The specific embodiment
A kind of shield machine receiving platform as depicted in figs. 1 and 2 comprises column 5, girder 1, secondary beam 3 and top board 4; Described column 5 is provided with at least three rows four row, all is fixed with bearing diagonal 2 between the horizontal and vertical two adjacent columns 5; Described every row column 5 tops all are fixed with girder 1 one; Described girder 1 top be fixed with every row's column 5 over against secondary beam 3; Described top board 4 is fixed at time top surface of the beam.
Described column 5 is a steel pipe, and described steel pipe bottom is fixed with mount pad 8, and the top is fixed with sealing steel plate 7, and is extremely shown in Figure 6 as Fig. 3.
Described girder 1 is an i iron, sealing steel plate 7 welding of described i iron bottom surface and column 5 end faces.
Described and every row column 5 corresponding secondary beams 3 comprise two i iron that are set up in parallel, and described i iron is welded on girder 1 end face.
In concrete application process, the quantity of column can carry out determining after the bearing capacity inspection is calculated according to the practice of construction situation, guarantee that overall structure can bear the pressure that produces in the shield machine receiving course, also need the downward pressure of bonding root post less than station back-plane design bearing pressure simultaneously, column is fixed on the base plate of station by bolt fixedly install mount pad in the column bottom after, on the column top sealing steel plate is set, each row column top all is provided with a girder, girder is an i iron, the general I56a that adopts, the length direction secondary beam vertical with its length direction is set on the girder end face again, and the per pass secondary beam all is located at directly over the column, secondary beam generally adopts I18 Two bors d's oeuveres i iron, the road number of secondary beam is identical with row's number of column, last on inferior top surface of the beam throat thickness greater than the top board of 20mm, the top board end face is as working platform, highly be suitable for receiving and hanging out shield machine from vertical shaft, when receiving shield machine, can on its end face, lay shield machine and receive carriage, finish shield machine smoothly and receive, dismounting and lifting; Present job practices is to wait in the station behind the plate casting complete, plate in the station is carried out shield machine as working platform to be received, finish plate cast in the station, and reach suitable intensity and need one month time at least, disclosed shield machine receiving platform sets up the 7 days left and right sides time of common need in the utility model, shorten the construction period greatly, also improved the service efficiency of shield machine.
