Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering and mass concrete pouring, and particularly relates to a centrifugal speed-controlled concrete pouring chute. Background Art

[0002] In building construction projects, the amount of concrete poured for the bottom slab of deep and large foundation pits is large, especially in busy areas with small operating areas. The pouring speed of traditional pump trucks is slow, fuel consumption is high, and the construction period is long. In order to increase the pouring rate of deep foundation pits, a chute pouring structure is generally used for pouring operations. When the chute pouring structure is in use, a large-diameter chute is used as a transportation pipeline for concrete, making full use of the concrete's own gravitational potential energy, setting a discharge chute and a discharge port at the top of the chute, and introducing concrete into the vertical chute. After passing through the buffer elbow, it enters the inclined chute and quickly reaches the pouring area. Then, with the branch chute and 360° steering device and other structures, combined with the flow range and initial setting of the concrete, the pouring range is adjusted in real time to achieve full-range pouring of concrete without blind spots, and comprehensively improve the efficiency of concrete pouring.

[0003] Patent: A chute casting structure for rapidly casting deep foundation pits (202322572970.6), discloses: the chute casting structure includes an inclined chute and a branch chute, the outside of the branch chute is provided with a first steel lattice frame and a second steel lattice frame, the inclined chute is provided with a diversion structure, and the diversion structure is located directly above the branch chute, the branch chute is detachably connected to the diversion structure, the inside of the branch chute is fixedly installed with a solenoid valve extending outside, the outside of the second steel lattice frame is provided with a feeding structure; the feeding structure includes a first unloading plate, a second unloading plate, a second telescopic cylinder and a mounting seat. This technical solution is mainly optimized from the perspective of facilitating the adjustment of the chute angle arrangement. The invention device is still limited by the site, and the structure is complex and not easy to arrange.

[0004] In traditional concrete pouring schemes, in order to avoid excessive speed during concrete pouring, the on-site chute must be arranged at a certain angle to avoid concrete segregation. However, this puts forward requirements for the layout of the chute and the size of the site, and increases the difficulty of verification. Utility Model Content
