Technical Field

[0001] This utility model relates to the field of concrete pouring technology in water conservancy construction, and in particular to a combined rapid concrete pouring chute. Background Technology

[0002] Currently, concrete pouring for water conservancy projects such as pumping stations, ship locks, inverted siphons, and control gates typically uses pump trucks or chutes. Chute pouring, in particular, is often hampered by the location of the pouring or road access, requiring frequent relocation of the pump truck and multiple dismantling and re-erection of the chute. Installing and dismantling a chute requires 8 people and takes one hour. The process involves personnel climbing scaffolding, posing significant safety risks. Furthermore, the one-hour interruption of concrete pouring can cause localized initial setting of the concrete, affecting the overall quality of the project. Utility Model Content

[0003] The purpose of this utility model is to solve the problems in the prior art mentioned above and to provide a combined rapid concrete pouring chute that does not require moving the concrete mixer truck or dismantling and rebuilding the chute during the pouring process, allowing for quick and convenient pouring of the surrounding walls.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A diversion platform for holding concrete;

[0007] A telescopic main channel is inclined and its lower end corresponds to the upper side of the diversion platform, through which concrete is injected into the diversion platform.

[0008] Several telescopic troughs are inclined and connected at the top to the edge of the diversion platform to discharge concrete from the diversion platform.

[0009] Furthermore, the diversion platform is a trough-shaped structure, and the bottom of the trough of the diversion platform is provided with a protrusion that is high in the center and low around the edges.

[0010] Furthermore, the edge of the diversion platform is provided with several U-shaped discharge ports, the upper end of the telescopic trough is rotatably connected to the discharge port, and the outer end of the discharge port is connected to a U-shaped flexible guide belt.

[0011] Furthermore, the upper end of the telescopic trough is provided with a flared section that is rotatably connected to the discharge port.

[0012] Furthermore, the discharge port is provided with a baffle, which is inserted into the inside of the discharge port.

[0013] Furthermore, a support is placed between the lower end of the telescopic main channel and the diversion platform.

[0014] Furthermore, a feeding hopper is connected to the lower end of the telescopic trough.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0032] Please see Figure 1-7 The chute for rapid concrete wall casting consists of a diversion platform 1, a telescopic main chute 2, and several telescopic sub-chutes 3.

[0033] The diversion platform 1 is used to hold concrete; the telescopic main channel 2 is inclined and its lower end corresponds to the upper side of the diversion platform 1 to inject concrete into the diversion platform 1; several telescopic sub-channels 3 are inclined and their upper ends are connected to the edge of the diversion platform 1 to discharge the concrete in the diversion platform 1.

[0034] This embodiment is applicable to the construction of the Kantuan South Station Pumping Station project in the Jiangshui Northward Diversion Section of the Yangtze River-Huaihe River Water Diversion Project. The surrounding walls to be poured are located within the foundation pit. Wall pouring templates are arranged around the foundation pit, and the poured walls are below ground level. Scaffolding is erected in the center of the foundation pit to support and stabilize the diversion platform 1. For example, horizontal steel pipes are used to support the diversion platform 1 on the lower side, and vertical steel pipes are used to limit the diversion platform 1 on all four sides. The lower end of the telescopic trough 3 is located on the upper side of the wall pouring template, and the upper and lower sides of the telescopic main trough 2 are supported by the edge of the foundation pit. The tanker unloading port is located on the upper side of the upper end of the telescopic main trough 2.

[0035] The diversion platform 1 is a square trough-shaped structure. The bottom of the trough of the diversion platform 1 has a protrusion 11 that is higher in the center and lower around the edges. The protrusion 11 is in the shape of a four-sided pyramid. The protrusion 11 can cause the concrete within the diversion platform 1 to move outwards, thereby moving the concrete towards the telescopic dividing trough 3 and preventing concrete from accumulating within the diversion platform 1. In some other embodiments, the diversion platform 1 can be configured as a circular trough structure, and the protrusion 11 as a conical structure.

[0036] The telescopic main channel 2 includes a first main channel 21 and a second main channel 22 that slides along the upper inner side of the first main channel 21. Both the first main channel 21 and the second main channel 22 are U-shaped channels. Both edges of the first main channel 21 and the second main channel 22 are provided with folded edges. Several bolts 23 are passed through the upper edge of the first main channel 21, and nuts are connected to the bolts 23. The edge of the second main channel 22 is provided with a first strip hole 24 that mates with the bolts 23.

[0037] Tightening the nuts clamps the edges of the first main channel 21 and the second main channel 22, fixing the length of the telescopic main channel 2 so that the upper and lower ends of the telescopic main channel 2 correspond to the tank truck and the diversion platform 1, respectively. Loosening the nuts without removing the nuts and bolts 23 allows the first main channel 21 and the second main channel 22 to slide, adjusting the length of the telescopic main channel 2 and thus improving its adaptability to different construction sites.

[0038] A support 4 is placed between the lower end of the telescopic main channel 2 and the diversion platform 1. The support 4 includes two columns 41, and a crossbar 42 connects the two columns 41. Each column 41 has a lower slot 43 on its lower side that engages with the side wall of the diversion platform 1. The support 4 can be placed on the side wall of the diversion platform 1 through the lower slot 43. Each column 41 has an upper slot 44 at its upper end. The lower end of the first main channel 21 has a support shaft 25. The two ends of the support shaft 25 rest in the upper slots 44 of the two columns 41, supporting the lower end of the telescopic main channel 2. Each end of the support shaft 25 has a limiting ring, which fits against the column 41 to prevent the support shaft 25 from axially misaligning within the upper slots 44.

[0039] The diversion platform 1 has several U-shaped discharge ports 12 along its edge. The upper end of the telescopic trough 3 is rotatably connected to the discharge port 12. The upper end of the telescopic trough 3 has a flared section 35 rotatably connected to the discharge port 12. The flared section 35 has a U-shaped structure and its width is greater than that of the discharge port 12. The lower wall of the flared section 35 fits against the lower side of the discharge port 12. A hinge seat 17 is provided on the lower side of the discharge port 12. The hinge seat 17 has an inverted T-shaped columnar structure. The lower wall of the flared section 35 has a through hole for the upper part of the hinge seat 17 to pass through, so that the flared section 35 and the telescopic trough 3 can rotate at the discharge port 12. In some other embodiments, the hinge seat 17 is set as a detachable structure, thereby making the telescopic trough 3 detachable.

[0040] The telescopic slot 3 includes a first slot 31 and a second slot 32 that slides along the lower outer side of the first slot 31. Both the first slot 31 and the second slot 32 are U-shaped slots. Both edges of the first slot 31 and the second slot 32 are provided with folded edges. The edge of the second slot 32 is provided with a slider 33. The slider 33 is a long strip structure with a T-shaped cross section. The edge of the first slot 31 is provided with a second strip hole 34 that slides with the slider 33. The second strip hole 34 allows the lower part of the slider 33 to pass through, so that the telescopic slot 3 can be extended and adjusted at any time.

[0041] The upper end of the first slot 31 is connected to the flared part 35. In this embodiment, both the first slot 31 and the second slot 32 are inclined, and both the flared part 35 and the discharge port 12 are horizontal.

[0042] Because the telescopic trough 3 can rotate outside the outlet 12, and because there is a rotation gap between the inner side of the flared part 35 and the outer side of the outlet 12, a U-shaped flexible guide belt 13 is connected to the outer end of the outlet 12 to prevent concrete from overflowing through the rotation gap. The flexible guide belt 13 is made of rubber or multi-layered fabric. The flexible guide belt 13 can not only rotate with the telescopic trough 3, making adaptive flexible deformations, but also its lower end extends into the inner side of the upper end of the first trough 31. When the telescopic trough 3 is at different angles, the flexible guide belt 13 can guide the concrete into the telescopic trough 3, preventing concrete overflow.

[0043] The lower end of the telescopic groove 3, i.e. the lower end of the second groove 32, is connected to a hopper 36. The lower end of the hopper 36 extends into the upper part of the wall casting template to prevent the telescopic groove 3 from extending and retracting. When it is necessary to change the casting position, the hopper 36 is moved and the telescopic groove 3 extends and retracts accordingly.

[0044] The discharge port 12 is equipped with a baffle 14, which is inserted into the inner side of the discharge port 12. In this embodiment, the inner wall of each discharge port 12 is provided with two sets of vertical grooves for the baffle 14 to be inserted into, a set of opposite deep grooves 15 and a set of opposite shallow grooves 16. When the baffle 14 is inserted into the shallow groove 16, there is a gap between the lower end of the baffle 14 and the lower wall of the discharge port 12 for concrete to pass through, which does not affect the delivery of concrete to the corresponding telescopic trough 3. When the baffle 14 is inserted into the deep groove 15, the lower end of the baffle 14 abuts against the lower wall of the discharge port 12, closing the discharge port 12. When a certain telescopic trough 3 is not in use, the corresponding discharge port 12 is closed by the baffle 14.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
