Description
Technical field
The present invention relates to tunnel open excavation half adverse construction method side in river is worn under a kind of method for tunnel construction more particularly to one kind
Method.
Background technology
It need to generally ensure that river water flow section, usual way are within river dry season when wearing river construction under open trench tunnel
Tunnel is built using Open Cut Method, the wet season restores river water flowing, but when dry season, the time was shorter, is applied in dry season tunnel
Work does not complete, and there are problems that river can not be restored in time in the wet season.
Invention content
The object of the present invention is to provide tunnel open excavation half reversed construction method in river is worn under one kind.Therefore, the present invention uses
Following technical scheme.
Tunnel open excavation half reversed construction method in river is worn under one kind, the described method comprises the following steps：
Step 1, in river bed construction foundation pit enclosure wall, Guan Liang is set in the coping of going along with sb. to guard him, excavates the river bed soil body to tunnel
Structure roof position；
Step 2 pours tunnel structure top plate in the tunnel structure ceiling location, and the top plate forms overlapping knot with enclosure wall
Structure；
Step 3 applies waterproof layer above the top plate, two side flangings of the waterproof layer to the Guan Liang bottom；
Step 4 is laid with protective layer in the top of the waterproof layer, and waterproof insulation blanket is arranged in the top of the protective layer, described
The both sides of waterproof insulation blanket wrap the Guan Liang；
Step 5 carries out earthing above the waterproof insulation blanket, restores river, from adjacent excavation of foundation pit top plate below the soil body to
Foundation pit bottom；
Step 6 pours tunnel structure bottom plate and tunnel structure side wall respectively, the bottom plate and the side wall with the enclosure wall
Iterative structure is formed, construction is completed.
Preferably, the enclosure wall, top plate and bottom plate and side wall are reinforced concrete structure.
Preferably, the top plate and bottom plate is connect with the reinforcing bar of the enclosure wall by reinforcing bar connector, 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 invention are as follows：It is shorter to solve river dry season, it is desirable that the fast quick-recovery river of open trench tunnel construction
The problem of；Wet season river water is avoided to flood the risk of open-cut foundation ditch；Using multiple tracks water proof safeguard procedures, the soil body below top plate is avoided
It excavates and structure pours period river water and penetrates into；Enclosure wall forms iterative structure with internal structure, and enclosure wall is whole with internal structure
Stress can reduce structure uneven subsidence, reduce construction risk.

Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Tunnel open excavation half reversed construction method in river is worn under one kind, is included the following steps：Step 1, in river bed construction foundation pit
Enclosure wall 1 is arranged Guan Liang 3 going along with sb. to guard him coping, excavates the river bed soil body 7 to tunnel structure ceiling location.Step 2, in tunnel
Structure roof position pours tunnel structure top plate 2, and top plate 2 forms iterative structure with enclosure wall 1.Step 3 applies above top plate
Waterproof layer 4, to Guan Liang bottom, waterproof layer needs to meet level-one waterproofing grade requirement two side flangings of waterproof layer.Step 4 is being prevented
The top of water layer 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, is protecting
The top setting waterproof insulation blanket 6 of layer, the both sides of waterproof insulation blanket wrap Guan Liang, setting waterproof insulation blanket use multiple tracks every
Water safeguard procedures avoid soil excavation and structure below top plate from pouring period river water infiltration, and the both sides of waterproof insulation blanket wrap
Guan Liang avoids river water from being penetrated by gap.Step 5 carries out earthing above waterproof insulation blanket, restores river, is opened from Adjacent Pit
Digging the soil body below top plate can carry out in the case of river recovery water flowing or river not water flowing below excavation top plate to foundation pit bottom
The construction of the soil body.Step 6 pours tunnel structure bottom plate 8 and tunnel structure side wall 9 respectively, bottom plate and side wall with enclosure wall shape
At iterative structure, construction is completed.Enclosure wall forms iterative structure with top plate, and strengthens the vertical bearing capacity of enclosure wall, encloses
The amount of reinforcement of revetment is higher than the amount of reinforcement of common enclosure wall by 5% ~ 10%, applying when reducing soil excavation below top plate
Work risk.Enclosure wall, top plate and bottom plate and side wall are reinforced concrete structure, the reinforcing bar of top plate and bottom plate and side wall with go along with sb. to guard him
The reinforcing bar of wall connects to form iterative structure by reinforcing bar connector, and enclosure wall forms iterative structure, i.e. enclosure wall with internal structure
It is respectively formed iterative structure with top plate and bottom plate and side wall, one, enclosure wall and internal structure entirety stress is formed, structure can be reduced
Uneven subsidence reduces construction risk.The tunnel structure that half reversed construction method of open cut applies is as described in Figure 1.
The above-described embodiments merely illustrate the principles and effects of the present invention, and is not intended to limit the present invention.It is any ripe
The personage for knowing this technology can all carry out modifications and changes to above-described embodiment without violating the spirit and scope of the present invention.Cause
This, institute is complete without departing from the spirit and technical ideas disclosed in the present invention by those of ordinary skill in the art such as
At all equivalent modifications or change, should by the present invention claim be covered.
