Embodiment 1

[0024] Such as figure 2 As shown, the tunnel body of this suspension steel-concrete composite structure suspended tunnel in water is a steel-concrete composite shell with an outer contour diameter of 10 to 15 meters. 3 are connected, relying on the tension of the suspension cable and the buoyancy of the structure to stabilize the floating tunnel 1 in the water, control the displacement and deformation of the tunnel within the allowable range, and ensure the structural safety of the tunnel and smooth driving. The steel-concrete composite shell is formed by sprinkling fine stone concrete 6 between the inner steel plate 5 and the outer steel plate 4. The two steel plate layers are used as the outermost layer and the inner shell of the floating tunnel body, and the pressure between the two steel plate layers is The fine stone concrete 6 is sprayed with a spray gun as the inner lining to form a steel concrete composite shell; in this embodiment, the tunnel cylinder is a single cyl...

Embodiment 2

[0033] combine image 3 , Figure 4 As shown, the tunnel body of this suspension steel-concrete combined structure floating tunnel in water is composed of two barrels arranged side by side, and the two barrels are connected to each other by high-strength bolts 8 at the side walls. A supporting frame 7 is provided in the tunnel body, and the supporting frame 7 is formed by connecting a longitudinal diaphragm and a transverse diaphragm. A secondary channel 14 and a gap are formed between the support frame 7 and the housing, and the support frame constitutes a driving lane 13, which is two lanes. The conveying pipeline is laid in the secondary passage 14, and a partition is laid on the conveying pipeline to form a passage. A secondary channel at the side wall of the tunnel body is an emergency evacuation channel, and the secondary channel is provided with an evacuation port 11; the upper part of the tunnel body is provided with an automatic drainage device 9 and a vent 10, and ...

Abstract

The invention relates to a suspended-cable steel-concrete composite-structured submerged floating tunnel and a construction method of the suspended-cable steel-concrete composite-structured submerged floating tunnel. The tunnel barrel body of the suspended-cable steel-concrete composite-structured submerged floating tunnel is a steel-concrete composite shell, the outer-contour diameter of the shell is 10 to 15 meters, a supporting frame is arranged in the tunnel barrel body, the supporting frame is formed by connecting longitudinal baffle plates and transverse baffle plates, an auxiliary passage and an air gap are formed between the supporting frame and the shell, a travelling lane is formed by the supporting frame, the travelling lane comprises two lanes, and the tunnel barrel-body part is connected with a submarine uplift pile through an anti-floating suspended cable; the steel-concrete composite shell is formed by pouring fine aggregate concrete into a position between an inner-layer steel plate and an outer-layer steel plate through spray irrigation; a transmission pipeline is laid in the auxiliary passage, and a passage is also formed by laying a baffle plate on the transmission pipeline; one auxiliary passage on the lateral wall of the tunnel barrel body is an emergency evacuation passage, and the auxiliary passage is provided with an evacuation opening; an automatic draining device and a ventilation opening are arranged at the upper part of the tunnel barrel body, and an automatic ventilating device is installed at the ventilation opening. The suspended-cable steel-concrete composite-structured submerged floating tunnel has good stability, the structural safety and the travelling steadiness of the tunnel are ensured, the construction method is simple, the tunnel is convenient to manufacture, and the usage amount of tunnel steel can be effectively reduced.

Description

1. Technical field: [0001] The invention relates to an underwater floating tunnel in the field of road bridges and culverts and marine engineering and a manufacturing and installation method thereof, in particular to an underwater floating tunnel with a steel-concrete composite structure of suspension cables and a construction method thereof. 2. Background technology: [0002] Due to the large amount of steel used in the proposed floating tunnel, the cost is high, the underwater stabilization measures and construction methods are cumbersome, the technical implementation is difficult, the stability, safety and comfort of the tunnel in the water are difficult to guarantee, and the safety factor is poor. 3. Contents of the invention: [0003] The object of the present invention is to provide a suspension tunnel in water with a steel-concrete composite structure and its construction method, which is used to solve the problems of large amount of steel used in existing suspension...
