Description

Technical Field

[0001] This utility model relates to the technical field of bridge pier pouring construction equipment, and more specifically, to a concrete diversion device for bridge pier construction. Background Technology

[0002] Currently, the construction and pouring of concrete for high bridge piers generally involves two methods. One method uses concrete pump trucks or truck-mounted pumps to deliver concrete from bottom to top through a pumping pipe. The concrete is then directly poured into the formwork through the pumping pipe, which is manually dragged back and forth during pouring. This method is labor-intensive and cannot be used for continuous pouring over long periods, resulting in low construction efficiency. Furthermore, the pumping pipe is a single-pipeline structure with only one concrete inlet. For high bridge piers, due to the large height of the formwork, the direct impact of concrete pouring into the formwork on the bottom area of ​​the pier formwork is significant, potentially causing quality issues during pier construction.

[0003] Another method is to use a concrete pouring funnel. After filling the funnel with concrete on the ground, a truck crane is used to lift the funnel to the pouring position, and the funnel gate valve is opened manually for pouring. This method also has a single concrete input port and is not suitable for high bridge piers. Utility Model Content

[0004] The purpose of this invention is to provide a concrete diversion device for the construction of high bridge piers. This device can divert the concrete inside the hopper to the surrounding area in a ring shape, and guide the concrete to be poured into the interior of the formwork from the inner edge of the formwork. This results in less impact on the bottom area of ​​the high bridge pier formwork, thus ensuring the quality of the pouring.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A concrete diversion device for bridge pier construction includes a bridge pier casting template. A diversion device is provided above the bridge pier casting template. The diversion device includes a bottom frame, which is fitted around the bridge pier casting template and fixed by a number of bolts at the front and rear. The upper surface of the bottom frame has upward protrusions at both the front and rear ends, and L-shaped support rods are provided on both sides of the top surface of the protrusions. The horizontal sections of the L-shaped support rods are connected inward to the outer side of a diversion cylinder with a rhomboid cross-section. A concrete inlet is connected to the top of the diversion cylinder. Four rectangular flow control valves are provided on the lower surface of the diversion cylinder, and each flow control valve is connected downward to a drainage hose through a flange.

[0007] As a further optimization of this solution, a ring is fitted on the outer side of the lower end of the drainage hose, and the outer vertical section of the ring is snapped onto the outer edge of the bridge pier casting template.

[0008] As a further optimization of this solution, the L-shaped support rod is welded and fixed to the outer side of the diverter cylinder.

[0009] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0010] This invention utilizes a rhomboid-shaped cross-section diversion cylinder to buffer and divert descending concrete, forming a central storage hopper structure that balances the pressure of the concrete in all directions. Combined with four drainage hoses below, which are fixed to the edge of the bridge pier casting template via ring buckles, the concrete is diverted to the corners of the inner side of the bridge pier casting template. The diverted concrete is poured into the template from the inner edge around the perimeter, minimizing the impact on the bottom area of ​​the bridge pier template and ensuring casting quality. Furthermore, by designing four independent flow control valves, the concrete flow rate of each drainage hose can be adaptively adjusted to ensure consistency of concrete flow rate in the four diversion directions.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0015] To address the issue that the existing pouring method has a single input port, and due to the large height of the formwork, the direct pouring of concrete causes a large impact on the bottom area of ​​the pier formwork, which may lead to quality problems in the pier construction;

[0016] like Figure 1 As shown, this application includes a bridge pier casting template 1. A diversion device is provided above the bridge pier casting template 1. The diversion device includes a bottom frame 2. The bottom frame 2 is fitted around the bridge pier casting template 1 and is tightened and fixed by several bolts 3 at the front and rear. The front and rear ends of the upper surface of the bottom frame 2 are both provided with upward protrusions, and L-shaped support rods 4 are provided on both sides of the top surface of the protrusions. The horizontal sections of the L-shaped support rods 4 are all connected inward to the outer side of the diversion cylinder 5 with a diamond-shaped cross-section. A concrete inlet 6 is connected above the diversion cylinder 5.

[0017] like Figure 2 As shown, the lower surface of the diversion cylinder 5 is provided with four flow control valves 9 arranged in a rectangular pattern. Each flow control valve 9 is connected to a flow guide hose 7 through a flange 10. A ring buckle 8 is fitted on the outer side of the lower end of the flow guide hose 7. The outer vertical section of the ring buckle 8 is clamped to the outer edge of the bridge pier casting formwork 1. The L-shaped support rod 4 is welded and fixed to the outer side of the diversion cylinder 5.

[0018] Specifically, a rhomboid-shaped diversion cylinder 5 is used to buffer the concrete inlet 6 as it descends and diverts the concrete, forming a central storage hopper module. This balances the pressure of the concrete in all directions. Combined with four drainage hoses 7 below, which are fixed to the edge of the bridge pier casting template 1 by rings 8, the concrete is diverted to the corners of the inner side of the bridge pier casting template 1. The diverted concrete is poured into the template from the inner edge around the template, resulting in less impact on the bottom area of ​​the bridge pier template 1 and ensuring the quality of the pouring. At the same time, by designing four independent flow control valves 9, the concrete flow rate of each drainage hose 7 can be adaptively adjusted to ensure the consistency of the concrete flow rate in the four diversion directions, further improving the pouring effect.
