Abstract
Description
Technical Field
[0001] This application relates to the field of water conservancy and hydropower construction, and more specifically, to a pouring device. Background Technology
[0002] In construction engineering, different types of wells are needed to meet functional requirements, facilitate maintenance and management, and ensure the safe operation of systems, such as gate wells and cable wells. During construction, the well walls need to be poured to enhance structural stability, provide protective functions, and improve performance.
[0003] Typically, concrete is transported from the wellhead to the pouring location using a gantry crane, or it is transported downwards to the pouring location using pipes installed vertically on the well wall.
[0004] However, when using gantry cranes to transport concrete, the discontinuous operation results in a lengthy pouring process. While pipeline transport can theoretically shorten pouring time due to its continuity, in practice, the aggregates, due to their weight and size, fall faster than the cement slurry during the downward transport of concrete through the pipeline. This causes concrete segregation, reducing the quality of the pour. Furthermore, the aggregates reaching the bottom of the pipeline before the cement slurry increases friction between the aggregates lacking a cement slurry coating, reducing their fluidity and making them prone to clogging at the bottom of the pipeline. Once a blockage occurs, clearing the pipeline takes a significant amount of time, further prolonging the overall pouring time. Utility Model Content
[0005] This application provides a pouring device that can improve pouring quality and shorten pouring time.
[0006] The pouring device provided in this application embodiment may include: a support structure, disposed in the well to be poured, wherein the sidewall of the support structure serves as a pouring template for the well wall; a guide structure, including a base, a funnel, and a chute; wherein the base is disposed on the support structure, the funnel is vertically fixedly disposed on the base, the chute is inclined, the high end of the chute is disposed at the junction of the funnel body and the funnel neck and communicates with the funnel body, and the low end of the chute is disposed above the pouring area of the well wall; and multiple conveying channels, each conveying channel including multiple pipes, wherein the multiple pipes are arranged in a manner that... Two adjacent pipes are connected by a buffer and then fixed vertically downwards to the well wall; multiple guide pipes correspond one-to-one with the multiple conveying channels, each guide pipe is inclined, the high end of each guide pipe is connected to the lower end of the corresponding conveying channel, and the low end of each guide pipe is located above the bucket body; wherein, concrete falls in the conveying channel, is buffered by the buffer, enters the guide pipe, is buffered by the inclined guide pipe, falls into the bucket body, enters the chute from the bucket body, and enters the pouring area after being buffered and guided by the inclined chute.
[0007] Optionally, the buffer is a cavity, with a first opening at the top and a second opening at the bottom of the cavity, away from the first opening. The cavity includes a first sidewall and a second sidewall connecting the first opening and the second opening. The top of the first sidewall is perpendicularly connected to the top of the cavity and close to the first opening. The second sidewall is inclined and located below the first opening. The top of the second sidewall is connected to the bottom of the first sidewall, and the bottom of the second sidewall is connected to the bottom of the cavity and close to the second opening. The first opening and the second opening are used to connect two adjacent pipes, respectively.
[0008] Optionally, the second sidewall is a plate-like structure; or, the second sidewall is a spiral-shaped flow channel.
[0009] Optionally, a low-frequency vibrator may also be attached to the outer wall of the buffer.
[0010] Optionally, a vibrator is also provided at the bottom of the chute.
[0011] Optionally, the flow guiding structure further includes: a first support rod, horizontally arranged, wherein one end of the first support rod is fixedly connected to the chute, and the other end of the first support rod is fixedly connected to the bucket neck; a working platform, fixedly arranged at the junction of the bucket body and the bucket neck and on a different side from the chute; a second support rod, inclinedly arranged, wherein the high end of the second support rod is fixedly connected to the lower side of the working platform, and the low end of the second support rod is fixedly connected to the bucket neck; an upper and lower channel, parallel to the chute, and the upper end of the upper and lower channel is connected to the working platform; and a guardrail, arranged on the outside of the working platform and the upper and lower channels.
[0012] The beneficial effects of the casting device in the embodiments of this application are:
[0013] Because buffers cushion the falling concrete, they unify the falling speed of aggregates and cement paste during the concrete's descent, preventing concrete segregation caused by differences in their falling speeds and improving both concrete and pouring quality. Furthermore, by unifying the falling speeds of aggregates and cement paste, separation is prevented, allowing the cement paste to coat the aggregates, reducing friction between them, improving fluidity, and decreasing the probability of concrete blockage in the conveying channel, thus shortening pouring time.
[0014] Furthermore, since the guide pipe and chute are inclined, they can buffer the concrete, further unify the speed of aggregate and cement paste in the concrete, further reduce the probability of concrete and aggregate separation, and thus further improve the quality of concrete and pouring.
[0015] Furthermore, because the concrete is continuously conveyed through the conveying channels, guide pipes, and chutes, the pouring time is shortened.
[0016] Furthermore, since the sidewalls of the supporting structure can serve as the casting template for the well wall to be poured, there is no need to make additional casting templates during the pouring of the well wall. Using the sidewalls of the supporting structure as casting templates reduces the pouring cost while achieving structural reuse. Attached Figure Description

It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation of the components in the accompanying drawings.
[0024] It should be noted that the terms "one" and "multiple" used in this utility model are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".
[0025] Figure 1 This is a schematic diagram of the structure of the casting device provided in the embodiments of this application, as shown below. Figure 1 As shown, the casting device may include: a support structure 110, a flow guiding structure 120, multiple conveying channels 130, and multiple guide pipes 140. Wherein:
[0026] The support structure 110 is installed in the well 100 to be poured, and the side wall of the support structure 110 serves as the pouring template for the well wall of the well 100. In other words, during the pouring of the well wall, there is no need to make an additional pouring template. The side wall of the support structure 110 is used as the pouring template, which reduces the pouring cost while realizing structural reuse.
[0027] Combination Figure 1 and Figure 2As shown, the flow guiding structure 120 may include a base 121, a funnel 122, and a chute 123. The base 121 is mounted on the support structure 110, the funnel 122 is vertically fixed on the base 121, and the chute 123 is inclined. The high end of the chute 123 is located at the junction of the funnel body and the neck of the funnel 122 and is connected to the funnel body. The low end of the chute 123 is located above the casting area of the well wall.
[0028] For example, the base 121 can be a concrete base including a steel plate, and the funnel 122 is fixed to the base 121 by fixing it to the steel plate in the base 121.
[0029] It should be noted that the guide structure 120 can rotate 360° under the push of the construction personnel to pour water at different locations in the pouring area.
[0030] Each delivery channel 130 includes multiple pipes, and two adjacent pipes are connected by a buffer 131 and then fixed vertically downward to the well wall.
[0031] It is understood that each conveying channel 130 is fixed vertically downwards to the well wall, and different conveying channels 130 are located in different positions, for example, in Figure 1 In the middle, two conveying channels 130 are arranged opposite each other. For each conveying channel 130, the conveying channel 130 includes multiple pipes, and two adjacent pipes of the multiple pipes are connected by a buffer 131.
[0032] Buffer 131 is used to cushion the falling concrete to unify the falling speed of aggregates and cement paste in the concrete. The number of buffers 131 and the length of the pipe can be determined according to the actual cushioning effect.
[0033] Multiple guide pipes 140 correspond one-to-one with multiple conveying channels 130. Each guide pipe 140 is inclined. The high end of each guide pipe 140 is connected to the lower end of the corresponding conveying channel 130. The low end of each guide pipe 140 is located above the bucket body.
[0034] The concrete delivery process during pouring can be described as follows:
[0035] The vehicle pours concrete into the conveying channel 130 from the top. The concrete falls in the conveying channel 130, is buffered by the buffer 131, and then enters the guide pipe 140. After being buffered by the inclined guide pipe 140, it falls into the bucket body and enters the chute 123. After being buffered and guided by the inclined chute 123, it enters the pouring area to pour the concrete.
[0036] Clearly, since the buffer 131 can cushion the falling concrete, it can unify the falling speed of the aggregate and cement paste in the concrete during the concrete's descent, thus avoiding concrete separation caused by the difference in falling speed between the aggregate and cement paste, thereby improving the quality of the concrete and the pouring quality. Simultaneously, by unifying the falling speed of the aggregate and cement paste, separation between them can be avoided, allowing the cement paste to coat the aggregate, reducing friction between the aggregates, improving fluidity, reducing the probability of concrete clogging in the conveying channel, and consequently reducing the pouring time.
[0037] Furthermore, since the guide pipe 140 and the chute 123 are inclined, they can buffer the concrete, further unify the speed of aggregate and cement paste in the concrete, further reduce the probability of concrete and aggregate separation, and thus further improve the quality of concrete and pouring quality.
[0038] Furthermore, since the concrete is continuously conveyed through the conveying channel 130, guide pipe 140, and chute 123, the pouring time is shortened.
[0039] Furthermore, since the side wall of the support structure 110 can be used as a casting template for the well wall of the well to be poured 100, there is no need to make an additional casting template during the pouring of the well wall. The side wall of the support structure 110 can be used as a casting template, which reduces the pouring cost while realizing the reuse of the structure.
[0040] It should be noted that this pouring device allows for segmented pouring of the well wall. Specifically, reinforcement is installed in the area to be poured, the support structure 110 is placed in the area to be poured, the guide mechanism 120 is placed on the support structure 110, and the conveying channel 130 and guide pipe 140 are installed simultaneously. The support structure 110 serves as the pouring template. After installation, the pouring device is used to pour the area to be poured. After pouring and during concrete setting, the positions of the conveying pipe 130 and guide pipe 140 are adjusted according to the location of the next area to be poured, and reinforcement is installed in the next area to be poured. After the concrete sets, the support structure 110 is moved to the next area to be poured, i.e., demolded, providing a pouring template for the next area, while also providing support for the guide structure 120, so that the area to be poured can be poured using the pouring device. This pouring process is repeated until the well wall is completely poured.
[0041] Clearly, in the above-mentioned segmented pouring process, the adjustment and installation of the relevant structures of the next area to be poured are carried out simultaneously during the concrete solidification process, which shortens the pouring time of the entire well wall and thus shortens the construction period.
[0042] In some possible implementations, such as Figure 3 and Figure 4 As shown, the structure of buffer 131 can be as follows:
[0043] The buffer 131 is a cavity 300, with a first opening 301 at the top and a second opening 302 at the bottom of the cavity 300 on the side away from the first opening 301.
[0044] The cavity 300 includes a first sidewall 303 and a second sidewall 304 connecting a first opening 301 and a second opening 302. The top end of the first sidewall 303 is vertically connected to the top of the cavity 300 and close to the first opening 301. The second sidewall 304 is inclined and located below the first opening 301. The top end of the second sidewall 304 is connected to the bottom end of the first sidewall 303, and the bottom end of the second sidewall 304 is connected to the bottom of the cavity 300 and close to the second opening 302. The first opening 301 and the second opening 302 are used to connect two adjacent pipes 305, respectively.
[0045] For example, such as Figure 3 As shown, the second sidewall 304 can be a plate-like structure. For example, the second sidewall 304 can also be a spiral-shaped flow channel.
[0046] Obviously, the first sidewall 303, being positioned at the top of the vertical cavity 300, provides a certain amount of space for the falling concrete to be contained and moved. The second sidewall 304, being inclined and located below the first opening 301, can buffer the concrete entering from the first opening 301, thereby unifying the falling speed of the aggregate and cement paste in the concrete, and guiding the concrete from the second opening 302 into the pipe 305 below.
[0047] Based on this, with the second sidewall 304 being a spiral-shaped flow channel, the spiral-shaped flow channel will mix the concrete during the process of concrete being transported in the spiral-shaped flow channel, further improving the quality of the concrete and the quality of the pouring.
[0048] In some possible implementations, a low-frequency vibrator may also be attached to the outer wall of the buffer 131. The low-frequency vibrator can further unify the speed of the aggregate and cement paste, making the aggregate and cement paste mix more evenly.
[0049] In some possible implementations, a vibrator may also be installed at the bottom of the chute 123. The vibrator can further unify the speed of the aggregate and cement paste, making the aggregate and cement paste mix more evenly.
[0050] In some possible implementations, such as Figure 2 As shown, the flow guiding structure 120 may further include: a first support rod 124, a working platform 125, a second support rod 126, an upper and lower passage 127, and a guardrail 128. Wherein:
[0051] The first support rod 124 is horizontally positioned, with one end fixedly connected to the slide 123 and the other end fixedly connected to the bucket neck. The working platform 125 is fixedly positioned at the junction of the bucket body and the bucket neck, and is located on a different side from the slide 123. The second support rod 126 is inclined, with its upper end fixedly connected to the lower side of the working platform 125 and its lower end fixedly connected to the bucket neck. The upper and lower passages 127 are parallel to the slide 123, and their upper ends communicate with the working platform 125. Guardrails 128 are located on the outside of the working platform 125 and the upper and lower passages 127.
[0052] Clearly, the stability of the chute 123 can be improved by setting the first support rod 124. The working platform 125 provides a platform for construction workers to observe the concrete delivery process. The stability of the working platform 125 can be improved by setting the second support rod 126. The access passage 127 provides a passage for construction workers to move from the working platform to the supporting structure 110, facilitating their ascent and descent. The guardrail 128 provides safety protection for construction workers.
[0053] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
