Abstract
The invention relates to a strengthening method for arranging a support inside a shield tunnel. A steel ring is arranged at a seam part of each segment of the shield tunnel to be strengthened and close to the inner wall of the segment; after the steel ring is mounted, the steel ring is provided with length passing I-shaped steels at four parts, comprising the upper, the lower, the left and the right parts, of the steel ring, in the longitudinal direction of the shield tunnel, an I-shaped steel support in the vertical direction and an I-shaped steel support in the vertical direction are erected at the position of the steel ring, and the two ends of I-shaped steel support in the horizontal direction and the two end of I-shaped steel supports in the vertical direction are respectively fixed inside the steel ring through the I-shaped steels; the I-shaped steel support in the horizontal direction and the I-shaped steel support in the horizontal direction are fixedly connected to an intersection. The strengthening method can form a circumferential and longitudinal integrated support structure inside the shield tunnel, so that the shield tunnel with the assembled structure is sufficient in circumferential and longitudinal rigidity and intensity under the action of supporting, and tunnel safety can be ensured under a condition that the loading condition at the rim of the shield tunnel is changed.
Description
Technical field
The present invention relates to underground structrue engineering technical field, be specifically related to the reinforcement means that a kind of shield tunnel inside arranges support.
Background technology
Shield method is built tunnel and is had the advantages such as speed of application is fast, workmanship is high, working security is good, more and more extensive in the application of the construction of tunnel such as subway sectional tunnel, highway tunnel, Hydraulic Tunnel, Urban Underground piping lane.In shield tunnel project, the stress condition in tunnel often changes, such as: the position residing for tunnel causes ground load to increase due to factors such as preloading, current heavy-duty vehicles, thus the strata pressure that shield tunnel is born changes; There are other underground engineering constructions such as excavation of foundation pit, piling, stratum high-pressure slip-casting, churning near tunnel, broken the ess-strain balance on stratum residing for tunnel, made tunnel produce distortion.This situation exists in a large number in the construction of underground construction.The engineering of closing on, once on the impact of the shield tunnel supporting capacity beyond shield tunnel construction, will certainly make shield tunnel that larger distortion occurs, thus cause the destruction in tunnel.Therefore, in this case, it is necessary for reinforcing shield tunnel.
Summary of the invention
Object of the present invention is exactly the reinforcement means proposing a kind of shield tunnel, and the reinforcement measure that the method adopts is rational in infrastructure, easy for installation, can play effective reinforcement effect to shield tunnel, thus ensures the safety of shield tunnel.
The technical solution adopted in the present invention is as follows:
Being close to section of jurisdiction inwall at the seam crossing of each endless tube sheet of the shield tunnel needed reinforcement adopts splicing to arrange steel loop; In steel loop upper and lower, left and right, 4 positions longitudinally adopt welding to arrange elongated i iron along tunnel; In tunnel, the i iron of every ring steel loop place erection horizontal direction and vertical direction supports, the bracing members two end supports of horizontal direction is on the elongated i iron of tunnel the right and left, the bracing members two ends support of vertical direction on the elongated i iron on upper and lower both sides, tunnel, thus is formed along tunnel hoop and longitudinal complete support system.
Beneficial effect of the present invention:
The present invention can form hoop and longitudinal complete braced structures in shield tunnel, make the structure of this pin-connected panel of shield tunnel under the effect supported, have enough hoops and longitudinal Rigidity and strength, ensure the safety in tunnel when tunnel shield structure road periphery loading condition changes.

Detailed description of the invention
Below in conjunction with accompanying drawing 1 embodiment, the present invention will be described.
Embodiment:
As shown in Figure 1, this is the reinforcement means that shield tunnel inside arranges support.
Detailed description of the invention is:
Be close to section of jurisdiction inwall at the seam crossing of each endless tube sheet of the shield tunnel needed reinforcement and arrange steel loop 1, steel loop 1 can adopt piecemeal to splice, and is convenient to transport and installs; After steel loop 1 installation, longitudinally arrange elongated i iron 2 in position, 4, steel loop 1 upper and lower, left and right along tunnel, i iron 2 adopts welding to be connected with steel loop 1; In tunnel, steel loop 1 place erection horizontal direction i iron supports 3 and vertical direction i iron support 4, and i iron supports 3,4 two end supports on elongated i iron 2, and guarantee is welded with i iron 2 after holding out against; Horizontal direction i iron support 3, vertical direction i iron support 4 infalls employings and are welded to connect, and reinforcement measure is provided with.This reinforcement measure can be removed according to the monitoring situation in tunnel after the underground construction completion closed on, and makes tunnel be able to normal use.
