Abstract
A sectional structure of cutting style for city rail transportation is an underground cutting structure with outlet on roof without ventilation device and air-conditioner, so for easy construction and low cost.
Description
Technical field
The present invention relates to tunnel-like, relate to a kind of road cutting type protecting interval structure that is used for city track traffic engineering concretely.
Background technology
Urban track traffic (being subway and light rail) has the overhead branch that lays with underground laying, and from the investment angle, overhead route is equivalent to 1/3 of underground cable, and running cost is significantly less than underground cable, and fire-fighting evacuation is better than underground cable greatly.But vibration, the noise of overhead route are very big to ambient influnence, deal with improperly civic landscape is brought negative effect, and the resistance of each metropolis enforcement overhead route is very big at present, and people do not welcome, and environmental impact assessment also is difficult to pass through.The interval, underground station of conventional design, because underground interval adopt shield method or Mine Method construction, because of the requirement (so causing the underground station must be designed to underground at least two layers station) that certain earthing is arranged, its investment cost and running cost afterwards are all very high, common civil engineering cost, single 7.2 ten thousand yuan/m in targe structure interval (two-wire), (two-wire) 3.56 ten thousand yuan/m between elevated region.Simultaneously for the underground interval of present employing, in case during interval fire, up to the present passenger's safe escape is solved as yet fully.
Summary of the invention
The objective of the invention is according to above-mentioned the deficiencies in the prior art part, a kind of road cutting type protecting interval structure that is used for city track traffic engineering is provided, the underground structure of this interval structure adopts the road cutting type protecting structure, its buried depth is shallow, structure roof is provided with opening, cancelled interval ventilation smoke exhaust equipment, the difficulty of construction of Jiang Diing reduces civil engineering and equipment investment and operation cost afterwards simultaneously greatly.
The object of the invention realizes being finished by following technical scheme:
A kind of road cutting type protecting interval structure that is used for city track traffic engineering, this underground structure comprises foundation structure, structure roof, it is characterized in that described top board is provided with opening.
It is complete opened type that described opening refers to this top board.
Described opening refers to this and offer a wind hole every at least 30 meters distance on top board.
The side of described opening is provided with greenbelt.
Advantage of the present invention is, adopt constructions such as low price SMW worker method owing to buried depth is shallow, can save interval ventilation smoke exhaust equipment, equipment drops into and running cost is basic and overhead route is approaching, so the cost of whole engineering is low, and civil engineering, equipment investment are few, operation cost is low, easy construction has overcome vibration, noise, the view defective big to ambient influnence of overhead route simultaneously, has solved safe escape under the fire working in the underground interval of conventional employing.
Description of drawings
Accompanying drawing 1 is the embodiment of the invention one a complete uncovered interval section;
Accompanying drawing 2 is a section between the embodiment of the invention two aperture area.
The specific embodiment
Feature of the present invention and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
Shown in Fig. 1-2, label 1-5 represents respectively: foundation structure 1, top board 2, complete uncovered 3, wind hole 4, greenbelt 5.
Embodiment one: present embodiment relates to the underground structure in underground interval, and this structure adopts open cut shallow embedding job practices, comprises foundation structure 1, complete uncovered 3, therefore can cancel the interval down routinely ventilation smoke exhaust equipment that is adopted.
Embodiment two: present embodiment relates to the underground structure in underground interval, this structure adopts open cut shallow embedding job practices, comprise foundation structure 1, structure roof 2, consider ground environment, after excavation is finished, restore in the employing greenery patches, apart from offering a wind hole 4, can cancel the down interval routinely ventilation smoke exhaust equipment that is adopted at top board 2 every 30m.
The scheme of the foregoing description one, two in the middle of the engineering both can having used separately, also can be combined and used in the engineering according to requirement of engineering.
The civil engineering cost of the foregoing description: the 4.3 ten thousand yuan/m in road cutting type protecting interval (two-wire), far below the cost in single targe structure interval (two-wire) in the prior art, and cost is approaching between elevated region.Running cost is basic suitable with overhead route, but is better than overhead greatly to ambient influnence (vibration, noise, civic landscape).
The foregoing description is applicable in the environment of greenbelt usually, does not generally use completely.
Claims (4)
1, a kind of road cutting type protecting interval structure that is used for city track traffic engineering comprises the earth construction and the underground structure at station, and this underground structure comprises foundation structure, structure roof, it is characterized in that described top board is provided with opening.
2,, it is characterized in that it is complete opened type that described opening refers to this top board according to the described a kind of road cutting type protecting interval that is used for city track traffic engineering of right claim 1.
