Abstract
The utility model relates to a tunnel, in particularly to an open-cut structure tunnel used for large-value stratum uneven settlements and faults. Said tunnel section size is larger the size of standard tunnel section and comprises at least two rectangular structures that are poured as a whole. The joint is arranged at the earth crack. The utility model has the advantages of simple structure and reliable quality, so can be used for large-value stratum uneven settlements and faults and can prevent damage to steel concrete segment in the tunnel.
Description
Technical field
The utility model relates to tunnel-like, relates to a kind of structure built by opencut method tunnel of the adaptable for large value stratum ununiform settling or changing of the relative positions concretely.
Background technology
Ground fissure be face of land rock-soil layer under natural cause and human factor effect, produce cracking and form the phenomenon in certain-length and width crack on ground.Ground fissure is the result of multifactor stack, and in the ground fissure activity system, its origin cause of formation act as the master with natural geology, and human factor is auxilliary.The activity of ground fissure has three-dimensional deformation characteristics, shows as vertical sedimentation, horizontal stretch-draw and twisting.
Because the activity of ground fissure is a dynamic change procedure, the origin cause of formation, mechanism and type are all very complicated, and has tangible segmented activity feature according to moving towards difference, the face of land that has has obviously and appears, the tool that has is lain concealed property, to build, the destruction form of structure also has nothing in common with each other, so the method for preventing and treating of engineering also should be at the different active situation and the space exhibition step characteristic of ground fissure, segmentation is considered.
At ground fissure active situation and space exhibition step characteristic, need relevant specialities such as circuit, structure, track and waterproof to take all factors into consideration.At first structure design will adapt to its different deformation requirements, the displacement of its generation is controlled in the default position and structure, and this body structure of tunnel is not damaged.In this scope, reserve enough deformation spaces simultaneously,, and handle joint waterproofing well so that adjust track circuit.
In the construction of tunnel of prior art, the ground fissure for a large amount of value stratum differential settlements or the changing of the relative positions cause for example in the above changing of the relative positions amount of 10mm, does not also have efficient ways at present.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, a kind of structure built by opencut method tunnel of the adaptable for large value stratum ununiform settling or changing of the relative positions is provided, this structure is when enlarging the shield tunnel section, increased the longitudinal flexible of structure, improved the compliance of structure the differential settlement and the changing of the relative positions.
The utility model purpose realizes being finished by following technical scheme:
A kind of structure built by opencut method tunnel of the adaptable for large value stratum ununiform settling or changing of the relative positions, this structure is built and is formed, be rectangular cross section, it is characterized in that the overall size of the overall size of described tunnel cross-section greater than structure built by opencut method tunnel standard section, if its difference is a Δ, described Δ value is satisfying under the safety factor of national Specification, and is corresponding with the discreet value of this structure location stratum differential settlement or changing of the relative positions maximum perpendicular displacement in design period.
Described structure built by opencut method tunnel is combined by the rectangular configuration that at least two monobloc casts form, and the seam between rectangular configuration and the structure is positioned at the ground fissure place that is caused by the stratum differential settlement or the changing of the relative positions that estimates.
The rectangular configuration that is arranged in the seam side is reserved with Grouting Pipe.
The base plate in described structure built by opencut method tunnel is arranged with sand cushion.
Be reserved with Grouting Pipe in the base plate in described structure built by opencut method tunnel.
The utility model has the advantages that simple in structure, reliable in quality can adapt to the stratum settlement and the changing of the relative positions of higher value, avoids the damage of reinforced concrete segment in the tunnel.
Summary of drawings
Accompanying drawing 1 is that the utility model Rectangular Tunnel facade is arranged schematic diagram;
Concrete technical scheme
The utility model feature 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:
As shown in Figure 1, label 1-6 represents respectively: rectangular configuration 1, seam 2, rectangular configuration 3, reservation Grouting Pipe 4, sedimentation space slip casting filling place 5, ground fissure 6.
Embodiment:
Vertical displacement amount in ground fissure position is bigger, the cross dimensions requirement of crack 6 places malformation contentedly of standard section design, therefore influence the structure built by opencut method tunnel that band scope domestic demand designs big section in ground fissure, take into full account the deflection that it causes because of the ground fissure development during metro operation.
The structure built by opencut method tunnel of present embodiment, be rectangular cross section, the overall size of tunnel cross-section is greater than the overall size of structure built by opencut method tunnel standard section, if its difference is a Δ, described Δ value is when design, should be according to the discreet value of ground fissure maximum perpendicular displacement in design period in the scope of design, consider that certain safety factor determines the design load Δ.
Present embodiment is reserved the malformation space, and design enlarges rectangular cross section, is the boundary with the ground fissure of estimating that is caused by the stratum differential settlement or the changing of the relative positions, the two ends cut and cover tunneling, and segmentation is built, and constitutes rectangular configuration 1,3, is seam 2 therebetween.
Structure is being provided with slide plane by ground fissure 6 places, and this joint area allowed certain slide down momentum when the vertically changing of the relative positions took place up and down on the stratum.
Be reserved with Grouting Pipe in the rectangular configuration 1,3 of seam 2 both sides, be reserved with Grouting Pipe 4 in the base plate in tunnel, can in time carry out slip casting and fill 5 the sedimentation space.
The base plate in tunnel is arranged with sand cushion.
