Description

Technical Field

[0001] This utility model relates to the field of tunnel sidewall pouring technology, specifically to an adjustable concrete chute pouring device. Background Technology

[0002] The concrete pouring of the tunnel's main structure sidewalls refers to the construction process of injecting prepared concrete into pre-installed formwork in layers, continuously and uniformly, and then using vibration equipment to fully compact it, thereby forming a lateral support structure with design strength, impermeability, and durability. Its core steps include formwork installation and reinforcement, layered concrete pouring, vibration to eliminate air bubbles and voids, and post-setting curing with moisture retention. Strict control of material proportions, water-cement ratios, and the construction environment is also necessary to ensure that the sidewalls can effectively resist earth pressure, water pressure, and external loads.

[0003] During the pouring of concrete for the side walls of the main tunnel structure, the side walls are usually quite high, generally exceeding 2 meters. Therefore, it is difficult for the concrete pump truck's pump pipe to be inserted into the bottom of the side wall formwork for pouring. Instead, the concrete can only be poured on the top side of the formwork, resulting in a high concrete discharge drop and segregation of concrete aggregates, which affects the quality of the side wall pouring and poses potential quality risks.

[0004] Therefore, to address the above problems, an adjustable concrete chute pouring device is proposed. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by developing an adjustable concrete tremie pipe casting device. This invention can improve the casting quality of concrete sidewalls, avoid concrete segregation caused by excessive concrete discharge drop, and is easy to install, dismantle, and reuse, thereby improving the quality and efficiency of sidewall casting construction.

[0006] To achieve the above objectives, this utility model employs the following technical solution: An adjustable concrete tremie pipe pouring device includes a connecting assembly that can connect to a concrete pump pipe. The connecting assembly is mounted on a support assembly and has a control switch for controlling the flow rate of concrete outside the outlet of the concrete pump pipe. The support assembly is detachably mounted on a receiving hopper via a limiting assembly, such that the connecting assembly is located in the middle of the upper side of the receiving hopper. The receiving hopper is in the shape of an inverted cone, and the bottom of the receiving hopper is connected to one end of a main water hose. The other end of the main water hose is detachably connected to a secondary water hose via a connector. The secondary water hose is used to insert into the side wall pouring formwork.

[0007] Preferably, the connecting assembly includes a concrete shut-off valve, the upper end of which is connected to the outlet of the concrete pump pipe, and the lower end of which is connected to the installation pipe. A control switch is installed on the installation pipe, which is rotatably mounted on the support assembly. An elbow is installed at the bottom of the installation pipe to guide the concrete flowing out of the installation pipe.

[0008] Preferably, the control switch is a butterfly valve, which is coaxially mounted in the middle of the mounting pipe.

[0009] Preferably, the support assembly includes an outer sleeve, which is rotatably fitted onto the outside of the mounting tube without affecting the use of the control switch. Several support rods are evenly arranged around the outer circumference of the outer sleeve. The farthest distance between the two ends of the support rods is not greater than the maximum diameter of the receiving hopper. A high-strength bolt is installed at the end of the support rod away from the outer sleeve. The high-strength bolt is used to connect the side of the receiving hopper.

[0010] Preferably, the limiting component includes a collar, with several collars evenly arranged circumferentially on the top side of the receiving hopper corresponding to the position of the support rod. The collar is fitted around the outside of the high-strength bolt to prevent the bolt head of the high-strength bolt from coming out of the collar.

[0011] Preferably, several slots are evenly opened on the outer side of the outer tube in the circumferential direction, with the length direction parallel to the axis of the outer tube. The upper and lower openings of the slots are spaced through. A plug is provided at the end of the support rod that is connected to the outer tube. The plug is inserted into the slot at intervals from the top or bottom.

[0012] As a preferred option, both the main hose and the auxiliary hose are made of nylon, and the connectors adopt a split hose zipper structure.

[0013] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages: This invention improves practicality by incorporating a connecting component to the outlet of a concrete pump pipe for guiding and controlling concrete pouring, facilitating construction according to specific needs. A funnel-shaped receiving hopper, integrated with the elbow of the connecting component, ensures that concrete flowing from the elbow first contacts the inner wall of the hopper, mitigating issues like aggregate segregation due to height differences and improving construction quality. Support and limiting components support and limit the position of the connecting component, preventing concrete spillage and material waste, thus enhancing stability and economy. The detachable support component on the receiving hopper facilitates installation and replacement, further improving economy and practicality. Multiple auxiliary water hoses, connectable via connectors, can extend into the bottom of the sidewall pouring formwork, adapting to various sidewall pouring heights and preventing aggregate segregation caused by height differences.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1-3 As shown, this utility model provides a technical solution: An adjustable concrete chute pouring device includes a connecting component 1, which connects to a concrete pump pipe, which is the discharge end of a concrete pump truck. The connecting component 1 is mounted on a support component 2 and has a control switch 3 for controlling the flow rate of concrete slurry outside the outlet of the concrete pump pipe. The support component 2 is detachably mounted on a receiving hopper 5 via a limiting component 4, which allows the connecting component 1 to be located in the middle of the upper side of the receiving hopper 5, resulting in better support stability. The receiving hopper 5 is an inverted conical funnel, with its bottom connected to one end of a main water hose 6. The other end of the main water hose 6 is detachably connected to a secondary water hose 8 via a connector 7. The secondary water hose 8 is used to insert into the side wall pouring template, and the pouring height of the secondary water hose 8 can be adjusted by the number of secondary water hoses 8 connected. The more secondary water hoses 8 connected, the closer the pouring height is to the bottom of the side wall pouring template.

[0019] In an optional embodiment, the connecting assembly 1 includes a concrete shut-off valve 11. The upper end of the concrete shut-off valve 11 is connected to the outlet of the concrete pump pipe, and the lower end of the concrete shut-off valve 11 is connected to the installation pipe 12. The concrete shut-off valve 11 serves as a connector. A control switch 3 is provided on the installation pipe 12. The installation pipe 12 is rotatably mounted on the support assembly 2 to avoid the torsion of the concrete pump pipe caused by angle issues, thus improving practicality. An elbow 13 is provided at the bottom of the installation pipe 12. The elbow 13 is used to guide the concrete flowing out of the installation pipe 12. Preferably, the elbow 13 is a universal ball joint elbow, which can adjust the orientation of the elbow 13 outlet and make the concrete flowing out of the elbow 13 outlet contact the inner wall of the receiving hopper 5 first, so as to slow down the flow rate of the concrete slurry, avoid pouring impact, and improve the pouring quality.

[0020] In an optional embodiment, the control switch 3 is a butterfly valve, which is coaxially disposed in the middle of the mounting pipe 12. Commonly available butterfly valves can be selected, which is more economical.

[0021] In an optional embodiment, the support assembly 2 includes an outer sleeve 21, which is rotatably sleeved on the outside of the mounting tube 12 to prevent the mounting tube 12 from coming off and to not affect the use of the control switch 3. Several support rods 22 are evenly arranged around the outer side of the outer sleeve 21 to support the outer sleeve 21. The farthest distance between the outer side of the outer sleeve 21 and the two ends of the support rods 22 is not greater than the maximum diameter of the receiving hopper 5 to facilitate disassembly and installation. A bolt hole is provided at the end of the support rod 22 away from the outer sleeve 21. The axis of the bolt hole is parallel to the length direction of the support rod 22. A high-strength bolt 23 is provided in the bolt hole and is used to connect the side of the receiving hopper 5.

[0022] In an optional embodiment, the limiting component 4 includes a collar 41. Several collars 41 are evenly arranged circumferentially on the top side of the receiving hopper 5 corresponding to the position of the support rod 22. The collars 41 are sleeved on the outside of the high-strength bolt 23 to prevent the bolt head of the high-strength bolt 23 from coming out of the collar 41. Specifically, the diameter of the threaded section of the high-strength bolt 23 is smaller than the inner diameter of the collar 41, and the diameter of the bolt head of the high-strength bolt 23 is larger than the inner diameter of the collar 41. When connecting the support rod 22, the high-strength bolt 23 can pass through the collar 41, and the degree of limiting on the outer collar 41 can be adjusted by the distance between the bolt and the bolt hole, which improves practicality.

[0023] In an optional embodiment, a plurality of slots 24 are evenly opened circumferentially on the outer side of the outer sleeve 21, with the length direction parallel to the axis of the outer sleeve 21. The slots 24 are preferably T-shaped slots, and the upper and lower openings of the slots 24 are spaced through the outer sleeve 21. The end of the support rod 22 connected to the outer sleeve 21 is provided with a plug 25 corresponding to the slot 24. The plugs 25 are inserted into the slots 24 at intervals from the top or bottom, which improves the stability of the support component 2.

[0024] In an optional embodiment, both the main hose 6 and the auxiliary hose 8 are made of nylon hoses, and the connector 7 adopts a split hose zipper structure. Preferably, a waterproof layer is provided on the inner or outer side of the zipper or a waterproof zipper is used to prevent concrete slurry from seeping out at the zipper, which is more economical and practical.

[0025] Working principle: First, the connecting component 1 is set on the receiving hopper 5 through the supporting component 2. The receiving hopper 5 can be set on the top of the side wall casting template or stuck on the inside of the side wall casting template. Then, according to the specific pouring height difference, the main water hose 6 is connected to several auxiliary water hoses 8 through the connector 7, so that the bottom of the lowest auxiliary water hose 8 can be located at the bottom of the side wall casting template. Then, the concrete pump pipe outlet is connected through the concrete shut-off valve 11 of the connecting component 1, the control switch 3 is closed, and the angle of the elbow 13 is adjusted so that the concrete flowing out from the outlet of the elbow 13 first contacts the inner wall of the receiving hopper 5, and then flows into the main water hose 6 along the inner wall, and then pours along the main water hose 6 and auxiliary water hoses 8 to the bottom of the side wall template. After pouring a section of concrete with the same length as the auxiliary water hose 8, the lowest auxiliary water hose 8 is removed to improve the pouring speed. After the pouring is completed, the supporting component 2 is removed to facilitate the transfer and storage of the device.
