Description
Technical field
The present invention relates to a kind of genuine reconstruction structure and its reconstruction method.
Background technology
It is genuine because it is not take up the characteristics of ground resource, landscape effect are good compared to overpass, it is rapid in urban road
It is used widely in transformation.Single-box multi-cell integral frame structure is past due to the advantages of its mechanical characteristic is good, floor space is small
Toward the underpass form for being first choice.But, it is contemplated that the distribution of present situation underground building thing, engineering time phasing in Practical Project
The factor such as demand, part tunnel is still designed to several separate type single box single chamber frame structures.With the continuous hair in city
Exhibition, transport need increasingly increases, and above-mentioned separate type tunnel needs original place to reconstruct and extend（Hereafter referred to collectively as reconstruct）.
Tunnel reconstruction when, should at utmost utilize existing underpass, it is generally the case that reconstruction tunnel structure preferably with original
It is genuine consistent, with the continuity of holding structure stress.However, on the premise of engineering specifications allows, if reconstruction tunnel can be used
The monolithic construction of single-box multi-cell, can reduce excavation of foundation pit area, save the concrete depressed place work amount of underpass, and reduction engineering is made
Valency.Based on this imagination, such as a kind of how construction method, by existing separate type it is genuine with reconstruction monoblock type is genuine is effectively connected,
Ensure do not occur leak, differential settlement etc. between the two, the problem of be urgent need to resolve.
The content of the invention

Embodiment
The present invention is illustrated with reference to a case history, accompanying drawing 5 is participated in, it is to be separated using the present invention
The embodiment schematic diagram of formula tunnel integration reconstruction.The tunnel was two separate type list box structures originally, now by its open section knot
Structure is cut, and two separate types are secretly buried into a section extended structure reconstructs into a monolithic construction.In separate type tunnel and monoblock type
Structural transition section is formed between tunnel to be used for connecting two kinds of underpass.However, the present invention is except go for will be multiple
Reconstruct into a monoblock type tunnel in separate type tunnel；It equally can be applicable to a monoblock type tunnel reconstructing into multiple separation
Formula is genuine.
Two separate type list box structures as shown in Figure 2, are each provided with the genuine top plate 1 of separate type, bottom plate 2, side wall 3,
The genuine internal kerbstone 4 set in side wall 3/3A and the junction of bottom plate 2, and genuine inner bottom surface mat formation 5.Symbol 14 is to divide
From the track clearance in formula tunnel.The side wall of wherein the two adjacent sides of separate type list box structure is adjacent side wall to be reconstructed
3A.In the present embodiment, the thickness for being spaced about one times of side wall between two adjacent side wall 3A to be reconstructed.
Monoblock type tunnel as shown in Figure 3 is single-box multi-cell（Two Room）Integral frame structure, comprising extending to, two Room are wide
The genuine top plate 6 of the monoblock type of degree, bottom plate 7, the mid-board 9 of the genuine adjacent side in two Room, two Room tunnels are located remotely from each other side
Side wall 8, the genuine internal kerbstone 10 set in side wall 8 or mid-board 9 with the junction of bottom plate 7 in each room, and each room are genuine internal
Bottom surface mats formation 11.Symbol 14 is the track clearance in the tunnel of each room.
As shown in figure 1, being reconstructed in the present embodiment to the genuine integration of separate type, comprise the following steps：
（1）The perforate slip casting 16 on the bottom plate of the both sides of the movement joint 12 between structural transition section and separate type are genuine,
Cheat bottom certain thickness formed below, the continuous strengthing body 17 of depth, it is intended to reduce the genuine differential settlement in both sides, and in reconstruction
Water-stop curtain is doubled as during genuine foundation pit construction.
（2）Building enclosure is applied again outside the genuine building enclosure of separate type, while excavation of foundation pit, cuts separate type
At genuine unlimited segment structure to movement joint 12, buried rubber fastening band and shear reinforcement in retaining in movement joint 12 are being poured
Utilized during building structure changeover portion.
（3）Two separate types tunnels are connected with monoblock type tunnel by structural transition section.At movement joint 12 so that knot
Top plate, bottom plate 21, outside side wall 22 connection corresponding with top plate 1, bottom plate 2, outside side wall 3 that separate type is genuine of structure changeover portion；
Also, it is provided with a Y type variable cross-sections wall 15 in structural transition section（Fig. 4）, pass through the two pass wall 18 of the Y type variable cross-sections wall 15
The adjacent side wall 3A genuine with separate type is connected；
At the movement joint 20 between structural transition section and monoblock type are genuine, make the top plate of structural transition section, bottom plate 21, outer
The single track wall 19 of side side wall 22, Y type variable cross-sections wall 15, genuine top plate 6, bottom plate 7, outside side wall 8, mid-board 9 with monoblock type
Correspondence connection.
In a preferred embodiment, the side that the wall thickness of the two pass wall 18 of the Y types variable cross-section wall 15 should be genuine with separate type
Wall 3A wall thickness is identical, and the wall thickness of single track wall 19 should be identical with the mid-board 9 that monoblock type is genuine；The inwall length A of two pass wall 18
（The length of correspondence Y type fork mouthful）Preferably 1 ~ 2m, the peripheral wall length B of two pass wall 18（The length of correspondence Y type fork mouthful is plus Y type fork mouthful
The length of the one section of wall in lower section）Preferably twice of A；Angle, θ at wall variable cross-section is preferably 135 degree.But in other examples
In, the dimensional parameters at each position of Y type variable cross-section walls can be adjusted, to adapt to that itself and separate type be genuine and monoblock type tunnel is connected
Actual conditions.
（4）After Y types construction wall is poured and finished, preferably the gap between two pass wall 18 is tamped with plain concrete；To ensure ground
Road waterproof effect, in addition to underpass uses water-tight concrete, still brushes water-repellent paint in genuine inwall.
（5）At the movement joint 12 and movement joint 20 set between structural transition section and two adjacent segments, waterproof measure is carried out.Knot
Structure changeover portion can be connected with the bottom plate that separate type is genuine and monoblock type is genuine by tongue-and-groove, or set drilling to fill below bottom plate
Stake is noted, with the uneven subsidence for solving underpass form, hole subsoil body difference is brought.
In some other examples, if actually it is necessary, or it is genuine monoblock type tunnel is transformed into separate type
When, description is seen above, for example can be on the bottom plate of the both sides of the movement joint 20 between structural transition section and monoblock type are genuine
Perforate slip casting, bottom certain thickness formed below, the continuous strengthing body of depth in hole.Either cut the genuine open section of monoblock type
Structure is to movement joint 20, buried rubber fastening band and shear reinforcement in retaining in movement joint 20, in pouring structure changeover portion
Utilized, etc..
Although present disclosure is discussed in detail by above preferred embodiment, but it should be appreciated that above-mentioned
Description is not considered as limitation of the present invention.After those skilled in the art have read the above, for the present invention's
A variety of modifications and substitutions all will be apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
