Description
Technical field
The utility model belongs to technical field of rail traffic, is to be related to a kind of underground station entrance knot more specifically
Structure.
Background technique
With the fast development in city, the urban track traffics such as subway and light rail are to alleviate the effective way of urban congestion.
Since urban land resource is in short supply, the city rail traffic routes such as subway are necessarily placed at underground sometimes, and entrance is as people
Member's access way, is a kind of necessary affiliated facility.If there are river, underground stations, and flood flowing district may be arranged in for surrounding city
Or the river courses for flood discharge periphery.Flood flowing district refers to usually only water, and the mistake for letting out Partial Flood can be divided when reaching a certain flood level
Pool.When meeting compared with great flood, it is necessary to open floodwater releasing port or by the unrestrained dike of regulation as flood discharge channel by defined place and width.River
Road includes riverbed and beach two parts.The river or section of dyke are built, flood is led off between Liang Di, in some rivers flood passages
Still there is resident to be engaged in agricultural production activity in area, there are also masses' inhabitations for some.It should be square when subway entrance is arranged in this position
Just normal use usually will also consider protection against erosion and flood problem under flood operating condition.Since structure of the subway design uses year
It is limited to 100 years, therefore design standard of flood control is generally 100 years one chances or 200 years one meet, in this case due to the trip of deep trouth
The influence of swinging property and ground affiliated facility, limiting scour is generally relatively deep, and the subway entrance of Normal practice is unable to satisfy anti-
It washes away, flood and anti-floating problem.Under limiting scour operating condition, the bottom soil body of conventional port structure will be flushed away,
Cause port structure destroy or can not normal use.In addition, also to prevent entrance from not flooded when reaching maximum flood water level
Not yet, subway normal operation is not influenced.Thus when underground station is built in flood flowing district or the river courses for flood discharge periphery, the structure of entrance
Design is a technical problem.
Utility model content

The supporting surface smoothly to connect with the section of climbing of the bottom plate is set between sinking section, for supporting top jointly with the section of climbing
Stair and staircase structure.
Further, the supporting surface passes through the support construction support being arranged between the barricade and the sinking section,
The support construction includes horizontally-supported and vertical supporting, and cavity, institute are formed between described horizontally-supported and vertical supporting
It states and backfills counterweight in cavity, be used for entrance anti-floating.
It further, further include the entrance ground Room, the current side of the personnel in the entrance ground Room is current mouth,
Remaining side is provided with flood barricade, and the flood for installing flood baffle is preset on the flood barricade adjacent with the current mouth
Lock slot, the flood baffle are used for the current mouth described in temporary enclosed in flood control, the flood barricade and the flood baffle
Top is higher than 100 years one chance flood level elevation lines.
Further, closed guard gate, institute are set in the horizontal channel of port structure section and the junction of underground station
State closed guard gate and Flood gate.
Further, in the horizontal channel of the bottom plate, section is equipped with for collecting the ponding into the port structure
Catch pit and drainage equipment for ponding to be discharged.
Further, drainage hole is set in the support construction, for introducing the water in the cavity of the support construction
In the catch pit.
The beneficial effect of underground station port structure provided by the utility model is:
Maximum when the sinking section of port structure close to above ground portion is set to flood operating condition by the utility model is washed away
Depth elevation line hereinafter, and between sinking section and ground setting can form the barricade of enclosed construction, efficiently solve entrance
Protection against erosion problem of the structure under flood operating condition avoids conventional port structure in the limiting scour lower plate lower part soil body
Cause floor structure to come to nothing by current scour, cantilever the case where, it is ensured that the safety of port structure；And pass through setting supporting surface
The stair or staircase structure for supporting top jointly with section of climbing after this section of bottom plate sinks, ensure that stair or staircase structure
Normal mounting.Therefore, the utility model is able to solve flood flowing district or the river courses for flood discharge periphery underground station port structure is anti-
The technical issues of washing away can be applied to the construction of flood flowing district or the river courses for flood discharge periphery subway station.
Further, the flood barricade that setting is increased in entrance ground Room border and the flood baffle increased, can be effective
Prevent the entrance under 100 years one chance flood operating conditions not to be submerged, and by the way that closed guard gate and Flood gate are merged setting, it is ensured that
Flood does not enter station under 200 years one chance flood operating conditions, to ensure that the normal operation of subway.Therefore, the utility model
The technical issues of being able to solve flood flowing district or the river courses for flood discharge periphery underground station port structure flood, can be applied to flood flowing district
Or the construction of the river courses for flood discharge periphery underground station entrance.
