Description
Technical field
The utility model relates to wear river tunnel under half adverse construction method of a kind of tunnel more particularly to a kind of open cut.
Background technique
It need to generally guarantee river water flow section when wearing river construction under open trench tunnel, usual way is within river dry season
Tunnel is built using Open Cut Method, the wet season restores river water flowing, but when dry season, the time was shorter, applies in dry season tunnel
Work does not complete, and there are problems that river can not be restored in time in the wet season.
Utility model content
The purpose of the utility model is to provide wear river tunnel under a kind of half adverse construction method of open cut.Therefore, this is practical new
Type uses following technical scheme.
River tunnel is worn under a kind of half adverse construction method of open cut, the tunnel includes enclosure wall, tunnel structure top plate, tunnel
Structure base slab and tunnel structure side wall, the tunnel further include waterproof layer, protective layer and waterproof insulation blanket；
The coping of going along with sb. to guard him is provided with crown beam；
The waterproof layer is arranged above the tunnel structure top plate, two lateral flanges of the waterproof layer to the crown beam bottom
Portion；
The top of the waterproof layer is arranged in the protective layer；
The top of the protective layer is arranged in the waterproof insulation blanket, and the two sides of the waterproof insulation blanket wrap the hat
Beam.
Preferably, the enclosure wall, top plate and bottom plate and side wall are reinforced concrete structure.
Preferably, the tunnel structure top plate, reinforcing bar of the tunnel structure bottom plate with the enclosure wall are plugged by reinforcing bar
Device connection, forms one.
Preferably, the protective layer is microlith element concrete structure.
Preferably, the thickness of the protective layer is not less than 0.3 meter.
The beneficial effects of the utility model are: it is shorter to solve river dry season, it is desirable that the fast quick-recovery of open trench tunnel construction
The problem of river；Wet season river water is avoided to flood the risk of open-cut foundation ditch；Using multiple tracks water proof safeguard procedures, avoid below top plate
River water penetrates into during soil excavation and structure pour；Enclosure wall and internal structure form iterative structure, enclosure wall and internal structure
Whole stress can reduce structure uneven subsidence, reduce construction risk.
Detailed description of the invention
Fig. 1 is tunnel structure schematic diagram in the utility model.
Description of symbols: 1, enclosure wall；2, top plate；3, crown beam；4, waterproof layer；5, protective layer；6, waterproof insulation blanket；7,
The river bed soil body；8, bottom plate；9, side wall.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Wear river tunnel under a kind of half adverse construction method of open cut, tunnel includes enclosure wall 1, top plate 2, bottom plate 8 and side wall 9,
Tunnel further includes waterproof layer 4, protective layer 5 and waterproof insulation blanket 6；The top of enclosure wall 1 is provided with crown beam 3.The setting of waterproof layer 4 exists
Above tunnel structure top plate, two lateral flanges of waterproof layer to crown beam bottom.The top of waterproof layer is arranged in protective layer.Anti- water segregation
The top of protective layer 5 is arranged in blanket 6, and the two sides of waterproof insulation blanket 6 wrap crown beam 3.Enclosure wall and top plate form iterative structure,
And the vertical bearing capacity of enclosure wall is strengthened, the amount of reinforcement of enclosure wall is higher than the amount of reinforcement of common enclosure wall by 5% ~
10%, reduce construction risk when soil excavation below top plate.Enclosure wall, top plate and bottom plate and side wall are armored concrete knot
The reinforcing bar of structure, top plate and bottom plate and side wall connect to form iterative structure by reinforcing bar connector with the reinforcing bar of enclosure wall, enclosure wall
Iterative structure is formed with internal structure, i.e. enclosure wall and top plate and bottom plate and side wall is respectively formed iterative structure, forms one, goes along with sb. to guard him
Wall and internal structure entirety stress can reduce structure uneven subsidence, reduce construction risk.Half reversed construction method of open cut
The tunnel structure applied is as described in Figure 1.
Tunnel open excavation half reversed construction method in river is worn under one kind, comprising the following steps: step 1, in river bed construction foundation pit
Enclosure wall 1 is going along with sb. to guard him coping setting crown beam 3, is excavating the river bed soil body 7 to tunnel structure ceiling location.Step 2, in tunnel
Structure roof position pours top plate 2, and top plate 2 and enclosure wall 1 form iterative structure.Step 3 applies waterproof layer 4 above top plate,
For two lateral flanges of waterproof layer to crown beam bottom, waterproof layer needs to meet level-one waterproofing grade requirement.Step 4, in the upper of waterproof layer
Side is laid with protective layer 5, and protective layer can be microlith element concrete structure, and the thickness of protective layer is not less than 0.3 meter, in the top of protective layer
Waterproof insulation blanket 6 is set, and the two sides of waterproof insulation blanket wrap crown beam, and setting waterproof insulation blanket uses the protection of multiple tracks water proof and arranges
It applies, avoids soil excavation and structure below top plate from pouring period river water infiltration, the two sides of waterproof insulation blanket wrap crown beam and avoid
River water is penetrated by gap.Step 5 carries out earthing above waterproof insulation blanket, restores river, excavates under top plate from Adjacent Pit
Necromancer body in the case that river restores water flowing or river not water flowing, can carry out applying for the excavation top plate lower section soil body to foundation pit bottom
Work.Step 6 pours bottom plate 8 and side wall 9 respectively, and bottom plate and side wall form iterative structure with enclosure wall, and construction is completed.
The above embodiments are only illustrative of the principle and efficacy of the utility model, and not for limitation, this is practical new
Type.Any person skilled in the art can all carry out above-described embodiment under the spirit and scope without prejudice to the utility model
Modifications and changes.Therefore, such as those of ordinary skill in the art without departing from the revealed essence of the utility model
All equivalent modifications or change completed under mind and technical idea, should be covered by the claim of the utility model.
