Abstract

The utility model discloses a diving tunnel crossing rivers, lakes and shallow seas, which is the connection that the land import, the underwater tunnel, the land export connect sequentially in the underwater tunnel. The diving Tunnel set an underwater pipelines whose both ends are respectively connected with the land import and export. the internal pipe is supported by steel bar, the external thereof is enwraped with steel net, round bamboo, felt, finally, iron sheet is used to seal the external pipe and make it not leak. The steps of builting diving tunnel are: place the underwater pipeline in the water, drain away water inside the pipe from the land import and export, reinforce the inner wall of pipeline with steel bar, pour cement, reserve various pipelines on the bottom and lay the road at last.

Description

The diving tunnel

Technical field

The utility model relates to a kind of traffic tunnel of building in rivers, lake and shallow sea, is a kind of excavation diving tunnel of native stone under water of need not digging at the bottom.

Background technology

At present, knownly cross the river to wear the subaqueous tunnel in lake or coastal waters (shallow sea) be to be formed by connecting by land import, subaqueous tunnel, land outlet.The subaqueous tunnel is in the mudstone of certain distance under water, dig earlier and excavate cavitation, re-lay reinforcing bar, casting cement forms, it is the great engineering that a technical difficulty is big, investment is big, many local rivers, lake and shallow seas, build bridge to be difficult for, to build the subaqueous tunnel and suffer from technology, manpower, financial resources again and limit, have to heave a sigh by Wang Yang (water).

Summary of the invention

The lake is worn in existing river and the deficiency that the subaqueous tunnel technical difficulty is big, investment is big is built in the shallow sea in order to overcome, the utility model provides a kind of diving tunnel, excavation is dug in the mudstone under water in this tunnel, but directly the tunnel is laid on the bottom, reduce the engineering difficulty effectively, saved investment, shortened the duration.

The technical scheme that its technical problem that solves the utility model adopts is: in the subaqueous tunnel, land import, subaqueous tunnel, land outlet connect, and a submarine pipeline is set, and pipe ends is imported and exported with land respectively be connected.In the pipeline for reinforced bar support, the sealing that is wrapped outward, its internal diameter and land import and export are equal to.In the pipeline, about 3 meters at every interval is provided with a steelframe circle that is supported by movable disk, travel(l)ing rest.Wear from inside to outside on the steelframe circle and prick the compound steel rib, a plurality of steel rings are set on the outer reinforcement bar, form a saturating empty reinforcing bar pipeline.Pipeline outer wall wraps up with steel mesh, circle bamboo, asphaltic felt, and outermost layer wraps up welded seal, also available superpower plastic film environmental sealing with the book iron sheet.Steel mesh can increase stress surface, and the circle bamboo is light, the property of bearing is arranged, both can bear pressure, again can be suitably crooked, and asphaltic felt is waterproof but also can relax outer pressure to round bamboo not only.The book iron sheet of sealing can prevent that sealing infiltrates in the pipeline.Place submarine pipeline,, dig and push water-bed mud grooving shape aside, will tie up wrapped pipe with special ship and slowly sink under water earlier along pipeline rout.During sinking, initial one section is not finely wrapped up, and allows in the water inlet pipe road, to keep the pipeline internal and external pressure balance.After treating at the bottom of whole pipeline cascading waters, lift The initial segment parcel back submerged again.Then, from the land import and export water in the pump drainage main road simultaneously, and inner-walls of duct reinforced steel, casting cement become the tunnel, remove movable disk, travel(l)ing rest, give when staying various cable tubing the bottom, and road surface pavement can be built up the diving tunnel in rivers, lake and shallow sea.

The beneficial effects of the utility model are, can build up traffic tunnel under water not digging under the situation of excavating water-bed mudstone tunnel, and engineering and technical difficulty are little, small investment, and benefit is obvious.
