Abstract
The utility model discloses a combination immersed tube for submarine tunnel belongs to underground or underwater structure technical field, and the purpose improves immersed tube mechanical properties, eliminates accident potential, improves production efficiency, and its technical scheme is, including reinforced concrete body, pipy interior guard plate and pipy outer guard plate in the constitution, interior guard plate cover is inside outer guard plate, the reinforced concrete body is pour between interior guard plate and outer guard plate. The utility model discloses set up inside and outside guard plate on the basis of traditional immersed tube, this kind of modular structure not only can prevent effectively that the immersed tube is impaired because of colliding with, improves the mechanical strength of immersed tube, and the phenomenon of droing can not appear in the inner wall moreover to eliminate the accident hidden danger, ensured the current safety in tunnel. In addition, the inner protection plate and the outer protection plate can also play a role in pouring a template, so that the manufacturing process of the immersed tube is simpler, and the production efficiency of the immersed tube is improved.
Description
Technical Field
The utility model relates to a combination immersed tube that uses when building submarine tunnel belongs to underground or underwater structure technical field.
Background
With the rapid development of modern science and technology, the construction technology of submarine tunnels is mature day by day, and more submarine tunnels are about to be constructed so as to meet the traffic demands of people. At present, the immersed tube for building the tunnel is mostly of a pure reinforced concrete structure, the immersed tube has the defects that the outer wall is difficult to avoid damage caused by collision, the integral strength is reduced, the inner wall is partially fallen, safety accidents are easy to cause, templates need to be assembled and disassembled in the manufacturing process, the operation is complex, the production efficiency is not high, and therefore improvement is necessary.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a combination immersed tube for submarine tunnel to the drawback of prior art to improve immersed tube mechanical properties, eliminate accident hidden danger, improve production efficiency.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a combined immersed tube for a submarine tunnel comprises a reinforced concrete tube body, a tubular inner protection plate and a tubular outer protection plate, wherein the inner protection plate is sleeved inside the outer protection plate, and the reinforced concrete tube body is poured between the inner protection plate and the outer protection plate.
The combined immersed tube for the submarine tunnel is characterized in that the inner protection plate and the outer protection plate are both steel corrugated plates.
The cross section of the reinforced concrete pipe body is circular, rectangular, trapezoidal or horseshoe-shaped.
The end part of the reinforced concrete pipe body is provided with the connecting flange.
The utility model discloses set up inside and outside guard plate on the basis of traditional immersed tube, this kind of modular structure not only can prevent effectively that the immersed tube is impaired because of colliding with, improves the mechanical strength of immersed tube, and the phenomenon of droing can not appear in the inner wall moreover to eliminate the accident hidden danger, ensured the current safety in tunnel. In addition, the inner protection plate and the outer protection plate can also play a role in pouring a template, so that the manufacturing process of the immersed tube is simpler, and the production efficiency of the immersed tube is improved.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
FIG. 1 is a schematic structural view of a composite sinking pipe with a circular cross section;
fig. 2 is a structural schematic diagram of a combined sinking pipe with a double horseshoe-shaped cross section.
The reference numbers in the figures are as follows: 1. outer guard plate, 2, reinforced concrete body, 3, interior guard plate.
Detailed Description
The utility model provides a steel buckled plate and reinforced concrete combination immersed tube, steel buckled plate are neotype building material, and the ductility of corrugated steel itself is good, and anti deformability is strong, still has the installation swiftly convenient simultaneously, saves the time limit for a project, and the processing cost is low, do benefit to advantages such as environmental protection, and consequently the structural strength of immersed tube can be improved in corrugated steel's application, reduces its cost of manufacture.
Referring to fig. 1 and 2, the cross section of the combined immersed tube may have different shapes, and the main structure thereof includes an outer protective plate 1, an inner protective plate 3, and a reinforced concrete tube body 2 poured therebetween, and both the outer protective plate 1 and the inner protective plate 3 are made of corrugated steel plates.
When the combined immersed tube is manufactured, the inner-layer steel corrugated plate and the outer-layer steel corrugated plate can play a role of a template, and a template does not need to be supported when middle concrete is poured.
The outer layer steel corrugated plate can prevent concrete from being collided and damaged in the hoisting, transporting and installing processes. The inner layer steel corrugated plate can prevent safety accidents caused by concrete falling off in the using process of the tunnel.
The use of the inner and outer layer steel corrugated plates can enhance the structural strength and reduce the using amount of reinforced concrete.
The steel corrugated plate needs to be subjected to corrosion resistance treatment, and particularly the outer layer steel corrugated plate needs to be subjected to seawater corrosion resistance treatment. The concrete anticorrosion scheme is required according to the water environment.
The flat corrugated plates can be in lap joint connection or flange connection, and the corner parts are preferably in flange connection or connected by other section steel connecting pieces.
The section of the immersed tube can be rectangular, circular, horseshoe-shaped, trapezoidal and the like.
