Abstract
The utility model discloses a soft stratum open-cut tunnel with deformation joints having anti-shearing functions, which has a rectangular frame structure consisting of a top plate, walls and a bottom plate. The deformation joints of the walls and the bottom plate are provided with anti-shearing structures respectively. By the aid of the anti-shearing structures in convex-concave chase mortise manner of the deformation joints, relative settlement of two sides of the tunnel on two sides of the deformation joints is avoided, and the open-cut tunnel is guaranteed to be used normally safely. Meanwhile, the anti-shearing structures are arranged on all the walls, so that packing in the deformation joints can be replaced easily and the packing can be filled into the deformation joint of the walls after the tunnel is constructed completely, and further, untimely stress of the packing is avoided and the service life thereof is prolonged. In addition, the anti-shearing structures are applicable to the soft stratum open-cut tunnel.
Description
Technical field
The utility model relates to open trench tunnel, refers to that particularly a kind of deformation joint has the soft stratum open trench tunnel of shearing resistance function.
Technical background
At present, open trench tunnel is made up of some sections rectangle frame assembling structures, in order to control tunnel generation distress in concrete, generally between each sections, deformation joint is set.But because existing deformation joint generally all adopts no shear structure (referring to Fig. 4), so adopt the deformation joint of this structure can't Transfer of Shear, the easy generation both sides relative settlement of the tunnel of deformation joint both sides influences the normal safe handling of open trench tunnel.
Summary of the invention
The purpose of the utility model is in order to solve the deficiency that the above-mentioned background technology exists, to provide a kind of simple in structure, easy construction and the soft stratum open trench tunnel with shearing resistance function.
For realizing above-mentioned purpose; The utility model adopts following technical scheme: a kind of deformation joint has the soft stratum open trench tunnel of shearing resistance function; This tunnel is the rectangular box-like structure of being made up of top board, body of wall and base plate, and the deformation joint of said body of wall and base plate is respectively equipped with shear structure.
In the such scheme, said shear structure is concavo-convex chase mortise, certainly, also can adopt other forms of shear structure.
In the such scheme; Shear structure on the said body of wall runs through whole body of wall along the thickness of wall body direction, and like this, the packing material in the deformation joint is changed easily; And because shear structure runs through whole body of wall; So can after constructing tunnel finishes, in the deformation joint of body of wall, pour into packing material again, avoid packing material stressed too early, prolonged the application life of packing material.
In the such scheme, the shear structure on the said base plate is arranged in the middle and lower part of base plate, has avoided base plate because of the stressed excessive shear failure that occurs.
The deformation joint of the utility model adopts the shear structure of concavo-convex chase mortise form, has prevented that the tunnel of deformation joint both sides from the both sides relative settlement taking place, and has guaranteed the normal safe handling of open trench tunnel; Simultaneously; Shear structure on the body of wall runs through whole body of wall, and like this, the packing material in the deformation joint is changed easily; And because shear structure runs through whole body of wall; So can after constructing tunnel finishes, in the deformation joint of body of wall, pour into packing material again, avoid packing material stressed too early, prolonged the application life of packing material.
The utility model is simple in structure, and easy construction and have the shearing resistance function has improved the application life of packing material in the deformation joint.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify:
As shown in Figure 1, present embodiment is the rectangular box-like structure of being made up of top board 1, body of wall 2 and base plate 3, and deformation joint 4 places of said body of wall 2 and base plate 3 are provided with concavo-convex chase mortise 5 respectively.Concavo-convex chase mortise 5 on the said body of wall 2 runs through whole body of wall 2 along body of wall 2 thickness directions; Like this; Packing material 6 in the deformation joint 4 is changed easily, and because concavo-convex chase mortise 5 runs through whole body of wall 2, so can after constructing tunnel finishes, in the deformation joint 4 of body of wall 2, pour into packing material 6 again; Avoid packing material 6 stressed too early, prolonged the application life of packing material 6.Concavo-convex chase mortise 5 on the said base plate 3 is arranged in the middle and lower part of base plate 3, has avoided base plate 3 because of the stressed excessive avalanche (referring to Fig. 2 and Fig. 3) that occurs.
As shown in Figure 2; During the utility model construction; The job practices of the concavo-convex chase mortise 5 on the body of wall 2 is: build one section tunnel earlier, and reserve the groove tenon part of said concavo-convex chase mortise 5 in the end in this section tunnel, and then build next section tunnel; And the tongue tenon part that partly matches at the interface setting in this section tunnel and epimere tunnel and the groove tenon of said concavo-convex chase mortise 5; In by two sections formed deformation joints 4 in tunnel, carry out corresponding waterproof measure more at last, and, form enclosed construction and get final product at 4 li perfusions of deformation joint packing material 6; Concavo-convex chase mortise 5 on the base plate 3 adopts general cut and cover tunneling (referring to Fig. 3).
