Abstract
A guide rail for shield construction comprises a guide rail, wherein the guide rail comprises a slope section and a straight section, and the slope section is connected with the straight section through a smooth connecting cambered surface; the guide rails are symmetrically arranged at the bottom of the portal steel ring and used for guiding, fixing and supporting the shield machine head, and the shield machine is guaranteed to move forwards according to the designed posture. The utility model discloses a draw rail simple structure, simple to operate can effectively avoid the shield structure machine to originate or receive when "kowtow" phenomenon, guarantees the shield structure machine correct axis trend.
Description
technical field:
The utility model relates to a kind of shield-tunneling construction auxiliary equipment, the approach rail be specifically related to a kind of shield launching, receiving.
background technology:
TBM's position control plays an important role at shield launching and reception stage, current shield machine when starting or receive mainly by start bracket and receive bracket to ensure shield attitude, start bracket or receive bracket and install precisely, can ensure the attitude of shield machine to a great extent.But as shown in Figure 1, when shield machine head is positioned between soil mass consolidation and bracket (shield machine bracket, Fig. 1 does not mark), be in vacant state when there is no the utility model approach rail 1, easy generation " is kowtowed " phenomenon, departs from Tunnel Design axis and affects tunnel Forming Quality.
Utility model content
Not enough for prior art, the utility model provides a kind of approach rail for shield-tunneling construction, prevents shield machine head from producing " kowtowing " phenomenon, ensures the axis trend that shield machine is correct.
The technical scheme in the invention for solving the above technical problem is:
For an approach rail for shield-tunneling construction, comprise approach rail, it is characterized in that: described approach rail comprises slope section and straightway, connect by the level and smooth cambered surface that connects between described slope section and straightway; Described approach rail is symmetricly set in bottom portal steel loop, for guiding, fixing and support shield machine head, ensures that shield machine moves ahead according to the attitude of design.
Further, described approach rail is common rail, adopts welding manner to be fixed on bottom portal steel loop.
Further, the plane of symmetry of described approach rail is mutually 60 ° of angles.
Further, described slope section is outside portal steel loop.
Further, described straightway is inside portal steel loop.
The advantage that the utility model possesses is: a kind of approach rail for shield-tunneling construction that the utility model provides, and it is with slope, can play good guiding, fixing and supporting role to shield machine into and out of the construction of portal steel loop; Approach rail structure of the present utility model is simple, easy for installation, " kowtowing " phenomenon when effectively can avoid shield launching or receive, and ensures the axis trend that shield machine is correct.
Accompanying drawing explanation
Fig. 1 is positional structure schematic diagram of the present utility model;
Fig. 2 is installation site of the present utility model schematic diagram;
Fig. 3 is the utility model structural representation.
In figure, 1, approach rail, 2, portal steel loop, 3, shield machine, 4, shield machine bracket, 5, soil mass consolidation, 6, side wall, 7, ground-connecting-wall, 11, slope section, 12, connect cambered surface, 13, straightway.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 2,3, a kind of approach rail for shield-tunneling construction, comprises approach rail 1, and described approach rail 1 comprises slope section 11 and straightway 13, connects between described slope section 11 and straightway 13 by the level and smooth cambered surface 12 that connects; Described approach rail 1 is symmetricly set in bottom portal steel loop 2, for guiding, fixing and support shield machine head, ensures that shield machine 3 moves ahead according to the attitude of design.
Further, described approach rail 1 is common rail, adopts welding manner to be fixed on bottom portal steel loop 2.
Further, as shown in Figure 2, the plane of symmetry of described approach rail 1 is mutually 60 ° of angles.
Further, described slope section 11 is outside portal steel loop 2.
Further, described straightway 13 is inside portal steel loop 2.
Concrete, as shown in Figure 1, 2, when shield machine carries out starting construction, approach rail 1 of the present utility model is installed bottom portal steel loop 2, when shield machine 3 head is pushed into approach rail 1 by shield machine bracket 4, straightway 13 can be risen to gradually along with the slope section 11 of approach rail 1, thus avoid because shield machine 3 head stretches out oversize and cause " kowtowing ".Shield machine 3 continues to tunnel forward, and approach rail 1 can play the effect of support, thus ensures that shield machine 3 moves ahead according to the attitude of design.
