Technical conceive of the present utility model is: tubular structure has a multilayer cross section that is made of three kinds of different raw material, thereby has realized " interlayer " configuration of this cross section: internal layer is made by iron and steel, and the middle level is made by concrete, and is outer made of aluminum.Therefore, this cross section has obtained the cooperative cooperating between the used raw material.Except that perishable, the characteristics of iron and steel are in light weight and have higher mechanical properties (tensile strength, fatigue resistance, shock resistance and ductility) because of structural element is little.Therefore, iron and steel places the inside of this structure, in case contact with water.Except that the tension force performance was low, concrete characteristics were that cost is low, can stablize weight under Archimedes's buoyancy, favorable mechanical performance and to the optimal response of water environment when compressing.Therefore, concrete is the middle level of this cross section, carries out different tasks, is not corroded as the protection iron and steel, guarantees counterweight, and with the steel pipe cooperation of axle position, guarantee the shearing resistance and the resistance to bending in tunnel.Iron and steel and concrete pipe are contemplated to be a composite construction.At last, except that fireproof performance and rigidity were low, the characteristics of aluminium were that corrosion resistance is strong, mechanical resistance and processing characteristics are strong.In view of the above, the outer companion that cellular aluminium type extrusion structure is used as this sandwich manages placement, to create an etch resistant layer.In addition, use if having external impact force, this aluminium type cellular structure to can be used as the ability absorber.
Anchor system is made by the wire rope of three kinds of series, and these wire rope are connected to this tunnel on the tunnel basis.The end of wire rope connects is conceived and is modeled to spherical linkage.From in essence, these spherical linkages are based on the notion of " suspension hook ".The anchoring suspension hook is a stainless steel suspension hook, is connected on the inner steel tunneltron by a bolt system.This bolt system is contained in the pyramid steel box of filling cement mortar.Cement mortar is cast between the steel layer and aluminium lamination of concreting, and is welded on the steel pipe.Native system is guaranteed suitable intensity and the rigidity that system connects, and makes things convenient for it to install, and hook member is also adopted in the anchor connection between tunnel and the tunnel basis.These members all are dissolved into during the basis builds.
The design of window concrete structure is led to outside aluminium lamination based on steel layer internally, allows concreting and guarantees the needs of fire resistance characteristic.Window glass is arranged in a pre-assembling box of being made by four blocks of aluminium sheets.Before concreting, aluminium sheet is inserted in Archimedes's bridge module.Window is closed by four clod wash stainless steel seamed edge members of inboard.
This joint is made of two steel loop flanges, and each flange all belongs in the adjacent block.Flange interconnects by the high strength steel anchor pole.Bolt flange is positioned at inner concrete and steel work layer.Constructed of aluminium layer externally, intermodule is pressed into a rubber ring, to guarantee the water proofing property of this connection.Place a slip rubber ring between steel and the al member, can be so that connect because of variations in temperature generation correlation displacement.
The beneficial effects of the utility model mainly show: 1, the anticorrosive property of tunnel body is good, has prolonged application life; 2, tunnel body and rope syndeton are installed simple; 3, the good waterproof performance of window; 4, sealing performance is strong between the pipeline section.
