Abstract
The utility model discloses a kind of concrete filled steel tube Cantilever Retaining Wall for high roadbed district.Described Cantilever Retaining Wall is reinforced concrete structure, comprises retaining wall, "T"-shapedly with base plate bottom retaining wall is connected; Be provided with one group of vertical steel pipe parallel with retaining wall short transverse in retaining wall, in base plate, be provided with one group of horizontal steel pipe parallel with floor length direction; Vertical steel pipe and horizontal steel pipe are all be filled with the concrete solid steel pipe of same specification.The utility model has good mechanical property within the scope of the engineering construction of high roadbed district, can have the ability of larger anti-large subsoil distortion, meanwhile, comparatively can reduce the consumption of concrete and reinforcing bar.The utility model can reduce the Resources for construction waste of high roadbed district, significantly reduces construction investment, easy construction, effectively can improve efficiency of construction, finally reach the object accelerating engineering construction progress.
Description
Technical field
the utility model relates to a kind of concrete filled steel tube Cantilever Retaining Wall for high roadbed district, belongs to civil engineering retaining structure technical field.
Background technology
because high roadbed district exists the problem that bearing capacity of foundation soil is lower and differential settlement is larger, therefore need the non-deformability improving retaining wall.As adopted existing steel concrete cantilever retaining wall structure, the sectional dimension of retaining wall can only be strengthened, the consumption of material will inevitably be increased, the problem of construction cost will certainly be caused.Therefore need to find one and can improve retaining wall non-deformability, again without the need to increasing the retaining wall structure of construction cost.
Utility model content
the purpose of this utility model is, provides a kind of concrete filled steel tube Cantilever Retaining Wall for high roadbed district, improves the non-deformability of retaining wall under the prerequisite not increasing construction cost.
the technical solution of the utility model:
for the concrete filled steel tube Cantilever Retaining Wall in high roadbed district, described Cantilever Retaining Wall is reinforced concrete structure, comprises retaining wall, "T"-shapedly with base plate bottom retaining wall is connected; Be provided with one group of vertical steel pipe parallel with retaining wall short transverse in retaining wall, in base plate, be provided with one group of horizontal steel pipe parallel with floor length direction; Vertical steel pipe and horizontal steel pipe are all be filled with the concrete solid steel pipe of same specification.
in aforementioned concrete filled steel tube Cantilever Retaining Wall, described one group of vertical steel pipe and the steel mesh reinforcement of one group of horizontal steel pipe through being positioned at one group of steel pipe both sides are located by connecting.
in aforementioned concrete filled steel tube Cantilever Retaining Wall, the gear soil face of described retaining wall and the junction of base plate are provided with chamfering.
in aforementioned concrete filled steel tube Cantilever Retaining Wall, the length B that described base plate stretches out retaining wall blocking soil face is less than the length C that base plate stretches out the retaining wall back side.
in aforementioned concrete filled steel tube Cantilever Retaining Wall, the length direction of described retaining wall is provided with one group of deformation joint, and the spacing of deformation joint is not more than 9 meters.
compared with prior art, the present invention adopts concrete filled steel tube Cantilever Retaining Wall to substitute the supporting and protection structure such as traditional concrete cantilever barricade, within the scope of the engineering construction of high roadbed district, there is good mechanical property, the ability of larger anti-large subsoil distortion can be had, meanwhile, the consumption of concrete and reinforcing bar can comparatively be reduced.The retaining wall adopting concrete filled steel tube Cantilever Retaining Wall of the present invention to form can reduce the Resources for construction waste of high roadbed district, significantly reduces construction investment, easy construction, effectively can improve efficiency of construction, finally reach the object accelerating engineering construction progress.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model;
fig. 2 is the A-A cross section view of Fig. 1.
being labeled as in accompanying drawing: 1-retaining wall, 2-base plate, 3-vertical steel pipe, the horizontal steel pipe of 4-, 5-same specification concrete, 6-steel mesh reinforcement, 7-chamfering.
Detailed description of the invention
below in conjunction with drawings and Examples, the utility model is described in further detail, but not as to any restriction of the present utility model.
for the concrete filled steel tube Cantilever Retaining Wall in high roadbed district, as depicted in figs. 1 and 2: described Cantilever Retaining Wall is reinforced concrete structure, comprise retaining wall 1, be connected with base plate 2 is "T"-shaped bottom retaining wall 1; Be provided with one group of vertical steel pipe 3 parallel with retaining wall 1 short transverse in retaining wall 1, in base plate 2, be provided with one group of horizontal steel pipe 4 parallel with base plate 2 length direction; Vertical steel pipe 3 and horizontal steel pipe 4 are all the solid steel pipes being filled with same specification concrete 5.One group of vertical steel pipe 3 and the steel mesh reinforcement 6 of one group of horizontal steel pipe 4 through being positioned at one group of steel pipe both sides are located by connecting.The gear soil face of retaining wall 1 and the junction of base plate 2 are provided with chamfering 7.Base plate 2 stretches out the length B that retaining wall 1 keeps off native face and is less than the length C that base plate 2 stretches out retaining wall 1 back side.The length direction of retaining wall 1 is provided with one group of deformation joint, and the spacing of deformation joint is not more than 9 meters.
Embodiment
this is such as shown in Fig. 1 and Fig. 2.During concrete enforcement, in retaining wall template, arrange one group of vertical steel pipe 4.One group of horizontal steel pipe 5 is arranged, horizontal steel pipe equidistant layout parallel with base plate 2 length direction in base plate template.All steel pipes are fixed by the steel mesh reinforcement 7 in template.Steel pipe two ends open-ended, when building retaining wall and base plate, concrete enters steel pipe simultaneously, makes steel pipe become solid steel pipe.This example adopts the mode of one-time-concreting, disposable retaining wall 1 and base plate 2 is built structure in aggregates.When the length of retaining wall is longer, should arrange deformation joint at the length direction of retaining wall, the spacing of deformation joint is not more than 9 meters.
