Description
Technical Field
The invention relates to the technical field of tunnel construction, in particular to a prefabricated assembly type structure for preventing a segment of an underwater shield tunnel from floating upwards, which is used for controlling the floating quantity generated when the segment is separated from the tail of a shield machine.
Background
In the shield method construction tunnel, the pipe piece can float upwards when having the following three conditions:
(1) liquid or fluid plastic body which generates buoyancy is arranged around the tunnel;
(2) the buoyancy generated by the outside is larger than the self weight of the duct piece;
(3) the upper portion of the tube sheet has a floating space or a compressible space.
The shield tunnel is a hollow cylinder and has a sinking trend under the action of the dead weight of concrete, but under the action of the buoyancy of full-section underground water or slurry, when the buoyancy borne by the segment is greater than the dead weight of the segment, if corresponding measures are not taken in time, the surrounding of the segment which is separated from the shield tail is in an unconstrained state surrounded by the underground water or the unset slurry, and the lining tunnel with excellent waterproof performance has a floating trend. Meanwhile, in the propelling process of the shield tunnel, the excavation section of the shield tunnel is larger than the outer diameter of the shield, so that a physical gap is inevitably formed between the surrounding rock and the duct piece after the duct piece is separated from the tail part of the shield tunnel, and a condition is created for the duct piece to float upwards. In addition, in the upper soft and lower hard stratum, due to the fact that the excavation face with different lithological properties, namely the upper, lower, left and right lithological properties and the uneven hardness is formed in the tunnel, the shield can move excessively in a snake shape in the tunneling process, and the building space between the duct piece and the surrounding rock is further enlarged. In a word, the underwater shield tunnel inevitably generates a floating phenomenon in the construction process. Therefore, the research on how to prevent the underwater shield tunnel segment from floating up has important guiding significance on the actual engineering.
In order to prevent the shield tunnel segment from floating upwards, a synchronous grouting measure is mainly adopted in the construction process, and the gap left during tunneling is filled in time by controlling the synchronous grouting amount and the grouting pressure. Chinese patent (application number: CN202010742073.3, published as 2020-10-16) discloses a grouting method for controlling upward floating of a duct piece in shield construction, which achieves the aim of quickly controlling upward floating of the duct piece by synchronous grouting and slurry pumping which are carried out simultaneously. However, when the duct piece is separated from the shield tail, the synchronous slurry behind the duct piece wall cannot be solidified in time, and the low-strength slurry cannot provide restraint for the duct piece and provides buoyancy on the contrary. The segment is anchored through the tensile member to ensure the stability of the segment. Chinese patent application No. CN202011559787.7 (published: 2021-04-09) discloses a method for preventing floating of a segment of a tube from occurring by abutting the segment with a stay inserted into the segment. But the cost of the tensile member is higher, and the connection mode of the tensile member and the duct piece is easy to cause the duct piece to be damaged under the action of larger buoyancy force, so that the waterproof performance of the tunnel is influenced. Therefore, a structure with simple structure, convenient construction and good use effect is designed, the floating problem existing after the duct piece is separated from the shield tail can be effectively solved, the linear design requirement of the tunnel is ensured, and the tunnel building limit is met.
