Description
Technical field
This patent relates to the visual plant device used on city track traffic engineering, suitable Subway Tunnel shield
Export & import is constructed.
Background technology
In Construction of Urban Rail Traffic, most of running tunnels use shield construction, after shield driving terminates
Needing construction reinforced bar concrete portal circle, therefore the active well base plate of shield launching position is at the bottom of than duct pieces of shield tunnel
Portion is low tens centimetres, and shield is such as placed directly on reinforced concrete floor and just cannot originate, it is therefore necessary to padded.
The padded material of shield is considered as can to repeatedly use with salvage material, will not damage, simultaneously
The requirement of intensity, rigidity, stability and globality can be met.As used backfill soil, backfill soil is met water and is softened,
Cannot reuse, the requirement of intensity, rigidity, stability and globality, shield and work can not be met simultaneously
Make the negative endless tube sheet absolute altitude in well uncontrollable, the assembled quality of positive endless tube sheet in affecting tunnel, thus cause leakage
The accidents such as water.As used Cast-in-situ Piles in Sand-filling, the requirement of intensity, rigidity, stability and globality can not be met equally.
Therefore the shaped steel shield pedestal being welded by shaped steel it is considered as.
Utility model content
This practicality is to be solved be technical problem is that: use different shaped steel and component, and assembly welding becomes at the bottom of one
Seat, can bear the weight of shield machine about 300t, simultaneously takes account of shield one end in soil, and the other end is at base
On seat, pedestal is by concentration power effect, it is ensured that shield pedestal will not damage by pressure, will not unstability and deformation.Simultaneously
Considering also will not unstability and deformation when lifting.Assembly welding wants simple simultaneously, and weight wants light and handy.
This practicality solves the technical scheme that used of above-mentioned technical problem: use 25b channel-section steel that welding is connect and
The beam become is as longeron 1 and crossbeam 2.The elongated setting of crossbeam 2, longeron 1 runs into crossbeam 2 and normal direction diagonal brace 3
Time block, and be connected with crossbeam 2 full weld.The a length of 4970mm of crossbeam 2, the clear distance between crossbeam 2 is
840mm, totally 10.Longeron 1 length 840mm, on same axial length direction 9, clear distance is 1240mm
And 1390mm, totally 54.The beam that spelling is welded by employing 25b channel-section steel is as the normal direction diagonal brace 3 of shield
With tangential diagonal brace 4.The a length of 1078mm of normal direction diagonal brace 3, the tangential a length of 1406mm of diagonal brace 4.Normal direction is oblique
Clear distance between support 3 is 840mm with the clear distance between crossbeam 2, and the clear distance between tangential diagonal brace 4 is with crossbeam 2
Between clear distance be 840mm.The rod member conduct with No. 10 channel-section steels, spelling being welded between normal direction diagonal brace 3
Stull 5 and diagonal brace 6, prevent normal direction diagonal brace 3 from unstability occurring.Normal direction diagonal brace 3 is 60 ° with the angle of crossbeam 2,
Tangential diagonal brace 4 is 30 ° with the angle of crossbeam 2.In contact point between normal direction diagonal brace 3 and crossbeam 2 in the heart
Away from for 4350mm.At welded top 300 × 300 × 20mm steel plate 7 of normal direction diagonal brace 3, upper at steel plate 7
The rail 8 of face welding 43kg/m.
Compared with prior art, the advantage of this practicality is: use simple several shaped steel assembly welding to become one
Pedestal, can meet the requirement of intensity, rigidity, stability and globality, the most lightweight, can reuse,
Setting out and receiving use of Subway Tunnel a diameter of 6340mm shield can be met.
As shield diameter changes, can adjust normal direction diagonal brace 3 and the positions and dimensions of tangential diagonal brace 4, normal direction is oblique
Support 3 and tangential angle between diagonal brace 4 and crossbeam 2 can be constant.As shield length dimension changes greatly, permissible
Strengthen the radical of longitudinal and cross beam thus strengthen the size of pedestal and solve, for general metro shield, length
Change is little, and this shield turns to pedestal to be suitable for.
This invention device can be saved manually, and accelerating construction progress is cost-effective.This invention device is through reality
Engineering is used for multiple times, it was demonstrated that can meet the requirement of intensity, rigidity, stability and globality.

Detailed description of the invention
Shield pedestal is steel construction Prefabricated, and shield base position, by design axis accurate settingout, is pressed during installation
According to the baseline of surveying and locating, hanging in down-hole installation in place, two track centerlines on pedestal press Tunnel Design axle
Line equidistant parallel is placed, and arranges bracing reinforcement.
Pedestal elevation direction is laid by design grade, and in-plane is put by straight line.
Below in conjunction with drawing, this practicality is described in further detail.
Fig. 1 is the structure front schematic view of this practicality.Use 25b channel-section steel to spelling the beam being welded as vertical
Beam 1 and crossbeam 2.Use 25b channel-section steel to spelling the beam that is welded as the normal direction diagonal brace 3 of shield and tangential
