Abstract
The utility model discloses a construction structure for a sewage pipe and a utility tunnel of a deep sludge foundation to penetrate through a center trench. The sewage pipe and the utility tunnel are arranged in the same underwater groove. The construction structure for the sewage pipe and the utility tunnel of the deep sludge foundation to penetrate through the center trench has the advantages that 1) due to the fact that the sewage pipe and the utility tunnel are arranged in the same groove, the shoring and protecting cost of a foundation pit is reduced, and the construction speed is high; 2) the sewage pipe and the utility tunnel are arranged in the same groove so that the width of the cross section of backfill sand can be shortened, the using amount of the sand is reduced, and construction cost is lowered; 3) backfill sand treatment is conducted on the constriction region, and compared with erecting of a temporary steel bridge, construction cost is reduced; 4) over-water construction is changed to be land construction, efficiency is improved, and safety and quality are guaranteed.
Description
Technical field
The utility model relates to the constructing structure that a kind of inverted-siphon soil pipe and integrated pipe canal pass through the center ditch, particularly relates to a kind of deep muck foundation soil pipe and integrated pipe canal and wears the center ditch and get over the subsea construction structure.
Background technology
At present, the job practices of submerged tunnel mainly contains: cofferdam cut and cover method, pneumatic caisson method, shield method and immersed tunnelling method, using more is shield method and immersed tunnelling method.Wherein, shield method adopts shield machine as the constructing tunnel facility.The shield machine shell is generally cylindrical shape, and its front portion is the otch ring of device excavation equipment, and the middle part is the supporting ring of device puopulsion equipment, and afterbody is the shield tail of shielding assembly unit lining cutting work.Advantage with shield construction is construction safety, does not affect water transportation.Shortcoming is that the tunnel length of leading the way is larger, and seam is more, and seepage easily occurs; When constructing in the section on the coast, surface settlement may occur, work the mischief.This method is used for the submerged tunnel construction of broken ground more.Immersed tunnelling method be submerged tunnel by designing requirement, prefabricate becomes pipeline section in the dock on the coast, then puts in place with the towboat transportation by driving, sinking is to dredging in advance in the groove that digs, and successively pipeline section coupled together under water, builds up the tunnel that passes through the waters.Its advantage is the tunnel good integrity of building up, good waterproof performance, lead the way shorter or the gradient more slow, can be used for the construction in large-sized rectangular cross section tunnel.Shortcoming is to affect water transportation.
Submarine pipeline generally has two kinds of paving modes: one) be laid on the bottom; Two) be embedded in the water-bed lower groove.
The mucky soil layer thickness is darker in the coastal area, need to consider simultaneously that integrated pipe canal and inverted-siphon soil pipe pass through the seabed, considers from construction technology and engineering cost two aspects, need to explore the integrated construction technology.
Summary of the invention
The utility model provides a kind of deep muck foundation soil pipe and integrated pipe canal to pass through the constructing structure of center ditch for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of deep muck foundation soil pipe and integrated pipe canal pass through center ditch construction structure, and described soil pipe and described integrated pipe canal are arranged in the same groove under water.
In the build of the described center ditch outside passage of drainning off floodwaters is arranged, at the construction area formation hydraulic fill sand land of described groove under water, construct in described hydraulic fill sand land described soil pipe and described integrated pipe canal.
Described soil pipe is inverted-siphon formula soil pipe.
Advantage and the good effect that the utlity model has are: 1) soil pipe and integrated pipe canal have reduced the supporting expense of foundation ditch with the groove setting, and speed of application is fast; 2) soil pipe and integrated pipe canal reduce hydraulic fill sand cross section width with groove, and sand using amount reduces, and construction cost reduces; 3) construction area is carried out hydraulic fill sand and process, compare with setting up the steel suspension bridge, reduce the operating expenses expenditure; 4) change the land construction into by over-water construction, efficient improves, and safety and quality are guaranteed.
Description of drawings
Fig. 1 is plan view of the present utility model;
Fig. 2 is profile of the present utility model;
Fig. 3 is the profile after the center ditch recovers navigation.
Among the figure: 1, integrated pipe canal, 2, soil pipe, 3, bridge, 4, groove under water, 5, hydraulic fill sand land.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1～Fig. 3, a kind of deep muck foundation soil pipe and integrated pipe canal pass through the constructing structure of center ditch, and described soil pipe 2 and described integrated pipe canal 1 are arranged in the same groove under water.
In the build of the described center ditch outside passage of drainning off floodwaters is arranged, at the construction area formation hydraulic fill sand land 5 of described groove under water 4, construct in the hydraulic fill sand land described soil pipe 2 and described integrated pipe canal 1.
Described soil pipe 2 is inverted-siphon formula soil pipe.
Job practices of the present utility model:
One) soil pipe 2 and integrated pipe canal 1 are put in order in same groove under water
Center ditch width 180m, the average 5m of the depth of water, the inverted-siphon soil pipe 2 that two initial plannings is positioned at bridge 3 east sides is relocated to bridge 3 west sides, makes itself and integrated pipe canal 1 in same groove under water 4, and pattern foundation pit supporting structure is only done once;
Two) form the land-based area works area
1) builds the passage that drains off floodwaters in the center ditch outside, discharge the center ditch for the water that guarantees the present situation sluice, establish in addition the wide passage that drains off floodwaters of 70m in the center ditch outside, adopt the gabion bank protection behind the irrigation canals and ditches excavation;
2) the center ditch in the road scope is carried out hydraulic fill sand and process the formation land-based area.The hydraulic fill sand scope also comprises the construction area of bridge 3, and its absolute altitude 1.7m identical with road, end face adopt cut into a mountain stone and 0.3m mud knot rubble of 0.5m to fill, and guarantee the current operation of big machinery;
Three) finish structure construction
Carry out the structure construction of bridge 3, soil pipe 2 and integrated pipe canal 1 at land-based area;
Four) rehabilitation center's ditch navigation
Structure construction is finished, and behind the pit backfill, and central excavation ditch hydraulic fill sand is to design navigation absolute altitude, rehabilitation center's ditch channel function that drains off floodwaters.
Although the above is described preferred embodiment of the present utility model by reference to the accompanying drawings; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away from the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection domain of the present utility model.
