Technical Field
The utility model relates to an instrument formula elephant trunk belongs to the construction field.
Background
With the development of cities, high-rise and super high-rise buildings are increasing day by day, the concrete volume of the foundation slab is also increasing, however, the number of roads which can be used for arrangement and construction is less and less. When large-volume concrete is poured, in order to avoid construction joints between new and old concrete, the pouring and tamping time interval is not required to be too long, so that the site arrangement and the pouring efficiency are particularly important.
The traditional construction method has two types: the other is to adopt an automobile pump for pouring, and the automobile pump is convenient to construct and flexible to pour, so that the concrete pump is one of the most common pouring modes for current concrete pouring. However, the car pump needs enough parking space when pouring, which limits the number of car pumps arranged in the field, so that the pouring efficiency is greatly reduced, and the noise is very loud when the car pump is poured, which is not beneficial to construction at night in downtown. The other method is to adopt a chute or a chute which is opposite to the automobile pump, so that the chute does not need a large space during pouring, the pouring speed is high, and no noise is generated during pouring of the automobile pump. The traditional method of the chute is to firstly erect a bent frame and place the chute or a chute on the bent frame. The bent frame is required to be erected on the cushion layer until reaching a natural terrace and is connected with the trestle outside the plane so as to ensure the stability of the bent frame. Then a chute or a chute is arranged on the bent frame, and a discharging funnel is arranged at the upper part of the bent frame. For a deep foundation pit, the height of the bent is very large, and the impact force of concrete on the pipe wall of the chute is also very large, so that the workload of erecting the bent is large, and the danger during erecting and concrete pouring construction is also very high. And the elephant trunk is erected, so that the elephant trunk cannot move and only a fixed small area can be poured. Therefore, the traditional chute construction method needs to set up bent frames, so that the workload is large in the early stage of casting, certain danger is caused during construction, the casting position is inflexible, and only a fixed small area can be cast.
Even when the above two methods are combined, the effect is not satisfactory. Because the pouring range of the elephant trunk is too small, most of concrete is still poured by adopting an automobile pump.
