Abstract
The pre-buried gutter structure of subway sectional tunnel waste water pump house, this structure not only can improve the corrosion resistance of drainage system, be conducive to the Maintenance and Repair of operating period simultaneously, can also reduce to greatest extent to close owing to just propping up structure the potential safety hazard brought not in time in passage construction process.Comprise the preliminary bracing structure covering tunnel surrounding, and be arranged on the secondary liner structure within preliminary bracing structure, preliminary bracing structure is made up of arch wall section, inverted arch section and crown section.Described inverted arch section is arcuate structure, applies the waterproofing course that loopful is closed in preliminary bracing structure Internal periphery surface.More than described inverted arch section, between waterproofing course and secondary liner structure bottom surface, arrange backfill layer, pre-buried gutter is embedded in this backfill layer.
Description
Technical field
The utility model relates to construction of tunnel, particularly relates to the pre-buried gutter structure of a kind of subway sectional tunnel waste water pump house.
Background technology
For meeting power conservation requirement, subway sectional tunnel longitudinal section is designed to " V " font longitudinal gradient all as far as possible, therefore need arrange waste water pump house near running tunnel minimum point, to meet tunnel minimum point drainage requirement.Current domestic subway sectional tunnel engineering arranges waste water pump house usually after main track is drawn by a bit of passage, and the current in main track tunnel enter in pump house via the gutter being embedded in below passage, two ends connect with main track tunnel drainage ditch and waste water pump house.
Current common way is when ground settlement and tunnel, in channel bottom slotting, and enters in stratum by drainpipe pre-buried, then carries out top tunnel structure construction.The shortcoming of this way is comparatively obvious, one, because subway engineering is century-old engineering, high to the life requirement of gutter, and the gutter buried underground directly contacts with stratum, be difficult to the application life ensureing drainage system, they are two years old, because gutter buries in the earth formation, later stage maintenance difficulty, to remedy cost higher; Further, need slotting to bury gutter underground due to channel bottom, in the area that formation condition is slightly poor, be unfavorable for that the quick closure of structure is just propped up in passage inverted arch position, in construction, there is certain potential safety hazard.
Based on above reason, be necessary further study the pre-buried gutter structure of traditional subway sectional tunnel waste water pump house and improve.
Utility model content
Technical problem to be solved in the utility model is to provide the pre-buried gutter structure of a kind of subway sectional tunnel waste water pump house, this structure not only can improve the corrosion resistance of drainage system, be conducive to the Maintenance and Repair of operating period simultaneously, can also reduce to greatest extent to close owing to just propping up structure the potential safety hazard brought not in time in passage construction process.
It is as follows that the utility model solves the problems of the technologies described above taked technical scheme:
The pre-buried gutter structure of subway sectional tunnel waste water pump house of the present utility model, comprise the preliminary bracing structure covering tunnel surrounding, and the secondary liner structure be arranged within preliminary bracing structure, preliminary bracing structure is made up of arch wall section, inverted arch section and crown section, it is characterized in that: described inverted arch section is arcuate structure, apply the waterproofing course that loopful is closed in preliminary bracing structure Internal periphery surface; More than described inverted arch section, between waterproofing course and secondary liner structure bottom surface, arrange backfill layer, pre-buried gutter is embedded in this backfill layer.
The beneficial effects of the utility model are, in work progress, passage preliminary bracing structure can be closed in time, substantially increases working security; Drainpipe pre-buried, in backfill layer, not only increases the corrosion resistance of drainage system, also the Maintenance and Repair of phase easy to use.
Accompanying drawing explanation
This manual comprises as next width accompanying drawing:
Fig. 1 is the profile of the pre-buried gutter structure of the utility model subway sectional tunnel waste water pump house.
Component name shown in figure and corresponding mark: arch wall section 11, inverted arch section 12, crown section 13, secondary liner structure 21, pre-buried gutter 31, backfill layer 41, waterproofing course 51.
Detailed description of the invention
Below in conjunction with accompanying drawing and concrete embodiment, the utility model is described in further detail.
As shown in Figure 1, the pre-buried gutter structure of subway sectional tunnel waste water pump house of the present utility model, comprise the preliminary bracing structure covering tunnel surrounding, and be arranged on the secondary liner structure 21 within preliminary bracing structure, preliminary bracing structure is made up of arch wall section 11, inverted arch section 12 and crown section 13.Described inverted arch section 12 is arcuate structure, applies the waterproofing course 51 that loopful is closed in preliminary bracing structure Internal periphery surface.Described inverted arch section more than 12, arranges backfill layer 41 between waterproofing course 51 and secondary liner structure 21 bottom surface, and pre-buried gutter 31 is embedded in this backfill layer 41.Passage preliminary bracing structure can be closed in time by waterproofing course 51, thus improves the safety of construction.Pre-buried gutter 31 reliably location and be not subject to formation influence and produce distortion, and under the protection being in backfill layer 41 water-proof and anti-corrosive material, therefore not only increase the application life of gutter 31, also the Maintenance and Repair of phase easy to use.
Usually, described backfill layer 41 can adopt the materials such as cement mortar, concrete or epoxy resin to fill, and described pre-buried gutter 31 can adopt ductile iron pipe, steel pipe or polyvinyl chloride (PVC) tubing.
The general principle of the pre-buried gutter structure of the above the utility model subway sectional tunnel waste water pump house that just explains through diagrams and structure, be not the utility model to be confined to shown in and in described concrete structure and parameter area, therefore every corresponding modify of being likely utilized and equivalent, all belong to the scope of the claims that the utility model is applied for.
