Description
Technical field
The utility model relates to construction of tunnel, particularly a kind of subway tunneling boring rock tunnel development machine engineering method tunnel water handling structure.
Background technology
Along with the fast development of current construction of tunnel, construction low-risk, high-quality, quick and little to ambient influnence tunneling boring rock tunnel development machine (Tunnel Boring Machine is called for short TBM) engineering method are progressively used and are promoted in city underground engineering rock quality layer.TBM engineering method tunnel lining structure has loopful prefabricated pipe section, loopful " preliminary bracing+secondary lining " composite lining, the prefabricated inverted arch block in bottom and top " preliminary bracing+secondary lining " composite lining to combine three kinds of forms.In, in slightly weathered rock stratum, the prefabricated inverted arch block in employing bottom, subway TBM tunnel and top " preliminary bracing+secondary lining " composite lining combining structure form, can have loopful prefabricated pipe section structural shape construction safety, fast and the advantage of loopful " preliminary bracing+secondary lining " form of structure economy concurrently.
According to current specifications requirement, subway sectional tunnel classification of waterproof is secondary, and prefabricated inverted arch block generally adopts the anti-aqueous mode of impermeable structure+seam waterproof for this reason; " preliminary bracing+secondary lining " form of structure generally arranges waterproofing course between supporting and secondary lining in the early stage, adopts the anti-aqueous mode of full bag.But in lithostratigraphy, underground water is generally Bedrock Crevice Water, the water yield is little, but head is higher; Adopt full bag waterproof, liner structure general thickness is comparatively large, and structure is born high hydraulic pressure for a long time and very easily caused seepage simultaneously, therefore have employed the design scheme of " anti-arrange in a row conjunction " at many geological conditionss good mountain ridge Tunneling by mining method.But due to the calcify reaction of percolating water and sprayed mortar, percolating water carry the deposition of a small amount of fine particle, slip casting alter starch, the reason such as concreting spillage, drainage system very easily blocks; Make the active force of hydraulic pressure to secondary lining be 1 ~ 2 times of design load after blocking, the hidden danger of the water pressure caused thus to structural safety is very large.
Based on above reason, be necessary to examine closely the waterproof and water drainage system of the prefabricated inverted arch block in employing bottom, subway TBM tunnel and top " preliminary bracing+secondary lining " composite lining combining structure and study.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of subway tunneling boring rock tunnel development machine engineering method tunnel water handling structure, effectively to meet tunnel water proofing requirement, and also easy for installation, drainage system self maintenance property is strong.
It is as follows that the utility model solves the problems of the technologies described above adopted technical scheme:
Subway tunneling boring rock tunnel development machine engineering method tunnel water handling structure of the present utility model, comprise the composite lining structure be made up of the prefabricated inverted arch block in bottom and top preliminary bracing, secondary lining, it is characterized in that: between described preliminary bracing, secondary lining, splash guard is set, between splash guard and preliminary bracing, band drain is set along circuit bearing of trend interval; In both sides, tunnel, arch springing arranges longitudinal drainage pipe, arranges transverse water drain pipe along interval, circuit bearing of trend both sides, and each transverse water drain pipe the inner is connected with this side longitudinal drainage pipe, and the gutter in this side line bed is then led in outside; The hoop end of described band drain is communicated with this side longitudinal drainage pipe.
Arch springing position, both sides, described tunnel arranges inspection-pit along circuit bearing of trend interval, and inspection-pit is positioned at the junction of transverse water drain pipe, longitudinal drainage pipe, and preliminary bracing, the secondary lining at this position are extending transversely in country rock.
The beneficial effects of the utility model are, the setting of this waterproof and water drainage system can reduce top secondary lining thickness, can arrange by the thick waterproof concrete minimum thickness of 250mm subway one-tunnel one-track tunnel structure thickness, arrangement of reinforcement only presses constructional reinforcement, therefore can cost saving greatly; This waterproof and water drainage system construction, easy for installation; Arrange inspection-pit, the later stage realizes cleaning to longitudinal drainage pipe and maintenance by inspection-pit, greatly reduces the risk of later stage discharge pipe line blocking, guarantees the safety of liner structure; Inspection-pit is positioned at outside tunnel clearance, can not cause adverse effect between turn(a)round to the normal use of running tunnel.
