Description
Technical field
The utility model belongs to foundation pit construction technical field, is related to a kind of interim bedding knot across Metro station excavation
Structure.
Background technology
In subway line building course, the subway station of soft clay area typically uses cut and cover tunneling, using cut and cover method
During construction, underground station need to first carry out foundation pit supporting construction construction, and foundation ditch could be excavated, then in constructed foundation ditch
Carry out the construction of station internal structure.But the intensive urban district of road network is placed in because subway station is standing, traffic pressure is larger,
During using cut and cover tunneling, the normal pass of vehicle can be hindered, causes the traffic in urban district further to deteriorate.
In order to reduce the influence caused during metro station construction to urban transportation, often use to set above foundation ditch and face
When bedding mode so that vehicle can pass through on interim bedding.And the interim bedding being currently mainly used has two kinds, respectively
It is：
1st, it is used as interim bedding using cast in situ reinforced concrete beam and floor；
2nd, army's suspension bridge using steel truss is used as interim bedding；
It is most commonly seen as interim bedding using cast in situ reinforced concrete beam and floor, but due to the width one of Metro station excavation
As be more than 20m, when set cast in situ reinforced concrete beam and floor when, in addition it is also necessary to set 2-3 arrange lattice column and pile foundation, can now deposit
In obvious shortcoming：
(1) lattice column set influences the waterproof effect of underground structure；
(2) work efficiency that the lattice column influence pit earthwork set is excavated.
During using army's suspension bridge of steel truss as interim bedding, there is also shortcoming：
(1) applicable foundation ditch span has limitation；When using army's suspension bridge of steel truss as interim bedding, foundation ditch across
Degree is generally no greater than 24m；
(2) army's suspension bridge rigidity of steel truss is smaller, and amount of deflection is larger, there is certain traffic safety hidden danger.
Utility model content
In order to overcome above-mentioned technological deficiency, the utility model provides a kind of interim bedding knot across Metro station excavation
Structure, ensure Metro station excavation construction period traffic above-ground it is unimpeded while, moreover it is possible to do not influence underground structure waterproof effect,

Seat top is provided with above the prior selection plate, the prior selection plate and is provided with the road
Surface layer.
Further, it is characterised in that：One group is respectively provided with below each two ends for first opening hair Prestressed cored beams or boards
The bearing.
Further, it is characterised in that：The foundation pit enclosure structure uses diaphram wall or campshed.
Further, it is characterised in that：The Guan Liang is monolithic reinforced concrete structure.
Further, it is characterised in that：Bearing described in every group has two bearings.
Further, it is characterised in that：The bearing is laminated rubber bearing.
Further, it is characterised in that：The supercrust is blacktop.
Further, it is characterised in that：The supercrust both sides are provided with intercepting ditch.
A kind of interim bedding structure across Metro station excavation described in the utility model, in Metro station excavation construction
Period, set above foundation pit enclosure structure and prior selection is set on setting bearing, bearing above Guan Liang, Guan Liang
Plate, supercrust is set above pre-tensioning system Prestressed cored beams or boards.
Compared with prior art, the beneficial effects of the utility model are：
(1) using this interim bedding of prior selection plate structure, not only can ground ensure traffic above-ground it is smooth
It is logical, and lattice column need not be set, the waterproof effect of underground structure is not interfered with, the matter of foundation pit construction has been favorably improved
Amount.
(2) using the structure of this interim bedding of prior selection plate, it is not necessary to set lattice column, Bu Huiying
The work efficiency that pit earthwork is excavated is rung, the efficiency of foundation pit construction has been effectively ensured.
(3) while the adaptability of prior selection plate is stronger, the larger foundation ditch of span can be used in, model is applicable
Enclose wide；
(4) and prior selection plate intensity it is high, when being used in the larger foundation ditch of span, also have stronger
Bearing capacity, can effective guarantee road vehicles normal pass.

Embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
As shown in FIG. 1 to 3, a kind of interim bedding structure across Metro station excavation described in the utility model, bag
Include foundation pit enclosure structure 1, Guan Liang 2, bearing 3, prior selection plate 4, supercrust 5, intercepting ditch 6.
In the present embodiment, the top of foundation pit enclosure structure 1 is provided with Guan Liang 2, and the top of Guan Liang 2 is provided with bearing 3, propped up
The top of seat 3 is provided with prior selection plate 4, and the top of prior selection plate 4 is provided with supercrust 5, road
The both sides of surface layer 5 are provided with intercepting ditch 6.
The foundation pit enclosure structure 1 is using the structure of diaphram wall, and during using this structure, Construction Vibration is small, wall
Rigidity is big, good integrity, and speed of application is fast, can save the cubic metre of earth and stone, and construction adaptability is strong, is applicable to various geological conditions.
But foundation pit enclosure structure 1 of the present utility model is not limited to this structure of diaphram wall, it would however also be possible to employ campshed etc. possesses perpendicular
To the structure of bearing capacity, it is clear that also among protection domain of the present utility model.
The top of foundation pit enclosure structure 1 is provided with the Guan Liang 2 of armored concrete, and Guan Liang 2 uses the knot of armored concrete
Structure both be can guarantee that and was reliably connected with building enclosure, and the cost of manufacture can be effectively reduced again.
