Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further illustrated.
With reference to Fig. 1, the float Structure that a kind of an ultra shallow of the present utility model buries shield tunnel includes that an ultra shallow is embedded in ground 1 time
Assembled, by concrete pipe sheet 7, the shield tunnel construction formed.Extend along circuit respectively outside the both sides of described shield tunnel construction
Interval, direction arranges left side pile foundation 6a, right side pile foundation 6b, and the top of each left side pile foundation 6a arranges and consolidates the left side being integrated with it
Pressing plate beam 5a, the top of each right side pile foundation 6b arranges and consolidates the right side pressing plate beam 5b being integrated, left side pressing plate beam 5a, right side with it
Arrange between pressing plate beam 5b and consolidate the anti-floating pressing plate 3 being integrated therewith.I.e. arrange outside shield tunnel construction by left side pressing plate beam
The pile slab structure that 5a, right side pressing plate beam 5b, left side pile foundation 6a, right side pile foundation 6b and anti-floating pressing plate 3 are formed, effectively solves an ultra shallow and buries
The technical problem of shield tunnel anti-floating, does not affect launching shaft, shield interval construction speed, reduces both sides, shield interval deep
Security of foundation ditch construction risk, it is ensured that engineering is implemented smoothly, advantageously reduces construction investment.And can be prevented effectively from during runing
Tunnel structure structure is damaged, makes the space on more than shield tunnel construction ground to be made full use of.
With reference to Fig. 1, formed by grouting and reinforcing in the soil body of shield tunnel construction outside below described anti-floating pressing plate 3
Pre-grouting reinforcing body 8.I.e. in shield tunneling process, 3 times soil bodys of anti-floating pressing plate are had around shield tunnel construction
Advanced Stabilizing Grout targetedly, makes soft stratum form consolidated earth mass, thus avoid excavated section occur " upper soft under
Firmly " or stratum discontinuity phenomenon, driving difficulty is caused.Under described anti-floating pressing plate 3 bottom surface, certain thickness concrete is set
Bed course 4, anti-floating pressing plate 3 end face is back fill course 2 to ground 1.
With reference to Fig. 1, a kind of an ultra shallow of this utility model buries work progress and the technology requirement of the float Structure of shield tunnel
As follows:
(1) construction on the left of pile foundation 6a, right side pile foundation 6b, dig out pile foundation end face and two campshed bases adjacent between the earthwork to coagulation
Bottom soil padding 4, and cut pile crown, straightening pile crown reinforcing bar；
(2) construction concrete cushion 4；
