Abstract
The utility model relates to a elephant trunk system suitable for high drop concrete placement for establish the arch bridge hunch seat concrete placement on precipitous massif, including a scaffold pipe of fixing on the massif, the scaffold is equipped with upper and lower two-stage inclined plane, two-stage elephant trunk about the fixed setting respectively on two inclined planes, and the concrete is through upper and lower two-stage elephant trunk buffering, can effectively overcome the segregation phenomenon that high drop caused.
Description
Technical Field
The utility model belongs to the technical field of the concrete placement construction, concretely relates to concrete chute system suitable for high drop concrete placement construction.
Background
The steel tube arch bridge has the advantages of large span, light structure, beautiful shape, good stability and shock resistance, and is often adopted in the design of bridges crossing river valleys. The arch support of the valley-crossing steel pipe arch bridge is generally positioned at the half-mountain waist of a mountain body and is generally positioned on a cliff, a large amount of concrete needs to be poured during the foundation construction of the arch support, the construction environment is limited, the concrete is generally poured downwards from the mountain top, and the concrete pouring quality is affected due to the fact that the fall is large and segregation is easy to occur during the concrete pouring.
Disclosure of Invention
The utility model aims at the above-mentioned problem, a elephant trunk system suitable for high drop concrete placement is provided, can overcome high drop concrete placement's segregation phenomenon, guarantees construction quality.
The technical scheme of the utility model as follows:
the utility model provides a elephant trunk system suitable for high drop concrete placement which characterized in that: the scaffold is erected on a mountain body, one surface of the scaffold facing the mountain body is fixed with the mountain body through an anchor rod, the surface facing away from the mountain body is provided with an upper inclined plane and a lower inclined plane, the two inclined planes incline outwards from top to bottom, and a certain fall is formed between the upper inclined plane and the lower inclined plane; the upper chute and the lower chute are respectively fixed on the upper inclined plane and the lower inclined plane of the scaffold through anchor ears along the inclined direction of the inclined plane of the scaffold, the upper end of the upper chute is provided with an upper chute feeding hole, the lower end pipe orifice is closed, and the bottom close to the lower end is provided with an upper chute discharging hole; the upper and lower end pipe orifices of the lower chute are all sealed, a lower chute feed inlet which is right opposite to the upper chute discharge outlet is arranged near the upper end of the lower chute, and a lower chute discharge outlet is arranged near the bottom surface at the lower end of the lower chute.
The utility model discloses simple structure, preparation are easy, and installation, dismantlement are convenient, and the practicality is strong, are applicable to high drop concrete placement, through two-stage buffer structure, can overcome high drop concrete placement's segregation problem, are particularly suitable for being located the hunch seat concrete placement construction on the massif cliff.

Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in fig. 1, the utility model comprises a scaffold 1, an upper chute 2 and a lower chute 3, wherein the scaffold 1 is erected on a mountain 4, one side of the scaffold facing the mountain is fixed with the mountain through an anchor rod, the side facing away from the mountain is provided with an upper inclined plane and a lower inclined plane, the two inclined planes incline outwards from top to bottom, and a certain fall is formed between the upper inclined plane and the lower inclined plane; the upper chute 2 and the lower chute 3 are respectively fixed on the upper inclined plane and the lower inclined plane of the scaffold through anchor ears 5 along the inclined direction of the inclined plane of the scaffold, the upper end of the upper chute 2 is provided with an upper chute feed inlet 6, the lower end pipe orifice is closed, and the bottom close to the lower end is provided with an upper chute discharge outlet 7; the upper end and the lower end of the lower chute 3 are sealed, a lower chute feed inlet 8 which is opposite to an upper chute discharge outlet 7 is arranged near the upper end of the lower chute, and a lower chute discharge outlet 9 is arranged near the bottom surface at the lower end of the lower chute.
The utility model discloses during the concrete implementation, can all establish the flange at the lower extreme mouth of pipe of last elephant trunk 2 and lower elephant trunk 3 to seal the mouth of pipe through a flange joint baffle 10.
The embodiment shown in figure 1 is used for the concrete pouring construction of the arch bridge arch seat on the cliff of the mountain. During construction, the scaffold 1 is erected on a mountain above the arch support 11 along the slope of the mountain 4, the scaffold and the mountain are fixed through anchor rods, the upper end of the upper chute 2 extends to the position of the concrete unloading truck 12, and the discharge port 9 of the lower chute is over against a pouring area of the arch support 11. The concrete discharging car 12 injects the concrete from the upper chute feed inlet 6, flows out from the upper chute discharge outlet 7, flows into the lower chute feed inlet 8 through a smaller fall, and finally falls into the arch support pouring area through the lower chute discharge outlet 9, and the concrete can effectively overcome the segregation phenomenon through two-stage buffering.
