Abstract
Under wear the crossings on different level tunnel construction of building, effectively to control the sedimentation in upper strata tunnel and existing building and deformation, avoid twice disturbing influence of the two space crossed constructing tunnels to building, it is ensured that the reliability and security of building are worn under crossings on different level tunnel.Including existing building and the upper strata tunnel, the lower floor tunnel that are disposed below being formed crossings on different level in stratum.Structure base slab left side pile foundation arranged below, the right side pile foundation in the upper strata tunnel, left side pile foundation, the top of right side pile foundation are fixedly connected with liner structure bottom plate, and lower floor tunnel passes through between left side pile foundation, right side pile foundation.
Description
Technical field
It the utility model is related to Tunnel Engineering, the crossings on different level tunnel construction of building worn under more particularly to a kind of
Background technology
With the rapid development of China railways tunnel construction, there is increasing crossings on different level tunnel, i.e., in space
Upper parallel, oblique, the tunnel of square crossing, and earth's surface building is worn under crossings on different level tunnel because the problems such as route selection, policy is present
The situation of thing.It is strict to requirement of settlement control that existing building construction is worn under crossings on different level tunnel, and upper and lower two constructing tunnels
Country rock can be produced compared with large disturbances, so as to which the sedimentation to surface buildingses, skew have an impact, bring certain safety hidden
Suffer from.If processing is bad, surface structures subsidence crack will be made, upper tunnel subsidence deformation, earth's surface building is destroyed and upper tunnel destroys
Larger economic loss will be caused.How to reduce influence of the lower constructing tunnel to upper tunnel and surface buildingses is to ensure solid
The key of architecture construction safety, and current urgent problem are worn under cross tunnel.
At present, it is more to the construction technologies such as tunnel underbridge beam, railway, building construction and safety control measures research, but
The research that surface buildingses are worn under crossings on different level tunnel is blank out, and this design and construction to three-dimensional cross tunnel is brought
Larger difficulty.
Utility model content
Technical problem to be solved in the utility model be to provide it is a kind of under wear the crossings on different level tunnel construction of building, with
Effectively control upper strata tunnel and existing building sedimentation and deformation, avoid two space crossed constructing tunnels to building twice
Disturbing influence, it is ensured that the reliability and security of building are worn under crossings on different level tunnel.
Technical scheme is as follows used by the utility model solves its technical problem：
Wear the crossings on different level tunnel construction of building under of the present utility model, including existing building and be disposed below ground
Upper strata tunnel, the lower floor tunnel of crossings on different level are formed in layer, it is characterized in that：The structure base slab left side arranged below in the upper strata tunnel
Side pile foundation, right side pile foundation, left side pile foundation, the top of right side pile foundation are fixedly connected with liner structure bottom plate, and lower floor tunnel is in left side
Passed through between pile foundation, right side pile foundation.
The beneficial effects of the utility model are effectively to control the sedimentation and deformation of upper strata tunnel and existing building, keep away
Exempted from twice disturbing influence of the two space crossed constructing tunnels to building, ensure that wear building under crossings on different level tunnel can
By property and security, reduce the risk of structure destruction, make to wear under crossings on different level tunnel the design of building more rationally, safety,
Reliably.
Brief description of the drawings
This specification includes following three width accompanying drawing：
Fig. 1 is sectional drawing (the face upper strata Under-cross tunnel for the crossings on different level tunnel construction that building is worn under the utility model
Section)；
Fig. 2 is sectional drawing (the face lower floor Under-cross tunnel for the crossings on different level tunnel construction that building is worn under the utility model
Section)；
Fig. 3 is the plan for the crossings on different level tunnel construction that building is worn under the utility model.
Component and corresponding mark are shown in figure：Existing building 10, upper strata tunnel 20, left side pile foundation 21, right side pile foundation
22, structure base slab 23, lower floor tunnel 30.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
Referring to Figures 1 and 2, the crossings on different level tunnel construction of building, including existing building are worn under of the present utility model
10 and it is disposed below upper strata tunnel 20, the lower floor tunnel 30 of formation crossings on different level on the stratum in.The structure in the upper strata tunnel 20
The left side pile foundation 21 arranged below of bottom plate 23, right side pile foundation 22, left side pile foundation 21, the top of right side pile foundation 22 and liner structure bottom plate
23 are fixedly connected, and lower floor tunnel 30 passes through between left side pile foundation 21, right side pile foundation 22.
Reference picture 1, left side pile foundation 21, right side pile foundation 22 are reinforced to upper strata tunnel 20, avoid constructing tunnel to existing
Building 10 causes to disturb twice.Using the construction of middle-wall method (CRD) method is intersected, left side excavation with guide pit supporting is complete in upper strata tunnel 20
Left side pile foundation 21 is applied after, right side base tunnel applies right side pile foundation 22 after the completion of applying.
Reference picture 3, the left side pile foundation 21, right side pile foundation 22 are respectively arranged at intervals two along the bearing of trend in lower floor tunnel 30
Root, the outside of lower floor's tunnel-liner 30 is arranged in, is applied from the liner structure bottom plate 23 in upper strata tunnel 20 to lower floor tunnel inverted arch bottom
Below portion, reduce lower floor tunnel 30 and excavate the influences such as sedimentation on upper strata tunnel 20 and existing building 10, skew.Lower floor's tunnel
Excavated again after the completion of the excavation supporting of upper strata tunnel 20, left side pile foundation 21, right side pile foundation 22 reach some strength in road 30.
Some the of the present utility model principles described above that simply explain through diagrams, are not intended to the utility model being confined to
In shown and described concrete structure and the scope of application, therefore every corresponding modification for being possible to be utilized and equivalent,
Belong to the apllied the scope of the claims of the utility model.
