Abstract
Description
Technical Field
[0001] This application relates to the field of tools for casting tunnel segments, and more particularly to a tool for casting steel ring glass fiber tunnel segments concrete. Background Technology
[0002] Currently, with the rapid development of urban construction, underground space has been widely developed and utilized, and subways have become one of the main modes of transportation. Before constructing a subway, underground tunnels need to be built. Lining segments are one of the main components of the tunnel. Multiple segments are spliced together to form the innermost permanent lining structure of the tunnel, bearing the responsibility of resisting soil pressure, groundwater pressure, and some special loads. Lining segments are generally made by pouring concrete into a mold. Before pouring, steel ring fiberglass segments are installed on the mold. After pouring, the steel ring fiberglass segments and the lining segments are cast as a whole. The steel ring fiberglass segments replace the internal steel reinforcement skeleton with a fiberglass reinforcement skeleton, taking advantage of the easy-to-cut characteristics of fiberglass to facilitate further processing later.
[0003] In related technologies, refer to Figure 1 The steel ring fiberglass tube 1 has multiple mutually separated chambers and fiberglass reinforcing bars running through these chambers. Multiple grouting holes 10 are formed on the surface of the steel ring template, each corresponding to a chamber. Concrete can be injected into the internal chambers of the steel ring template through these grouting holes 10. Typically, a concrete pump and pipeline are used to pour the concrete into the grouting holes 10.
[0004] Regarding the aforementioned technologies, the inventors believe that: during concrete pouring, the accuracy of the operation can easily cause concrete overflow; in addition, when the cavity under one of the grouting holes 10 is filled, the pipe needs to be transferred to another grouting hole 10, and concrete overflow is inevitable during the pouring and transfer of the pipe; the overflowing concrete not only wastes raw materials, but also adheres to the steel ring template, causing inconvenience for later cleaning. Summary of the Invention
[0005] In order to improve the accuracy and efficiency of concrete pouring and reduce the waste of raw materials, this application provides a concrete pouring tool for steel ring glass fiber tube segments.
[0006] The concrete pouring tool for steel ring fiberglass tube segments provided in this application adopts the following technical solution:
[0007] A concrete pouring tool for steel ring fiberglass tube segments, used in conjunction with steel ring fiberglass tube segments having multiple grouting holes, includes a hopper for receiving concrete and multiple funnels disposed at the bottom of the hopper and communicating with the hopper; the hopper is adapted to the steel ring fiberglass tube segments; the number and position of the funnels correspond to the grouting holes, and when a funnel is inserted into a grouting hole, the outer wall of the funnel abuts against the opening of the grouting hole and seals the grouting hole.
[0008] By adopting the above technical solution, before pouring, the silo is placed on the steel ring fiberglass tube sheet, and the funnel is inserted into multiple grouting holes accordingly. The outer wall of the funnel abuts against the opening of the grouting hole and seals it. Concrete is then injected into the silo using a pouring device, allowing the concrete to be precisely poured into each grouting hole through the funnel, reducing concrete overflow due to operational inaccuracies. Multiple grouting holes can be poured simultaneously, avoiding concrete overflow caused by the transfer of pipes between holes. When one grouting hole is full, excess concrete remains in the silo, further reducing concrete overflow. In summary, by setting up the silo and funnel, the accuracy and efficiency of concrete pouring are improved, and material waste is reduced.
[0009] Optionally, the hopper includes a base plate and a frame; the base plate includes multiple detachably connected plate units, and the frame is detachably connected to the base plate.
[0010] By adopting the above technical solution, when transferring the silo, the frame can be disassembled first, then the plate unit can be disassembled, and then the plate unit and frame can be spliced on another steel ring fiberglass tube sheet that needs to be cast, which improves the convenience of silo storage and transfer.
[0011] Optionally, a first mounting plate is provided on the frame, and a second mounting plate and a third mounting plate are respectively provided on adjacent plate units. After the hopper is assembled, the first mounting plate, the second mounting plate and the third mounting plate overlap. The first mounting plate, the second mounting plate and the third mounting plate are simultaneously fixed by fasteners.
[0012] By adopting the above technical solution, when assembling the hopper, the adjacent plate units are first assembled, and then the frame is placed on the assembled base plate. At this time, the first mounting plate, the second mounting plate and the third mounting plate are in an overlapping state. Then, the plate units and the frame can be fixed at the same time using fasteners, which improves the convenience of assembling and disassembling the hopper.
[0013] Optionally, the fixing component includes a sliding rod, a limiting wristband disposed at one end of the sliding rod, and a positioning block protruding from the outer wall of the sliding rod on the side away from the limiting wristband; the sliding rod can slide through the first mounting plate, the second mounting plate, and the third mounting plate while restricting the first mounting plate, the second mounting plate, and the third mounting plate between the limiting wristband and the positioning block; the sliding rod can rotate about an axis, and the second mounting plate and the third mounting plate are provided with holes through which the sliding rod can communicate with the positioning block to pass or be pulled out.
[0014] By adopting the above technical solution, when assembling the hopper, adjacent plate units are first assembled, and then the frame is placed on the assembled base plate. At this time, the first mounting plate, the second mounting plate, and the third mounting plate are in an overlapping state. A sliding rod is used to pass through the holes on the first mounting plate, as well as the second and third mounting plates. By rotating the sliding rod, the positioning block is misaligned with the hole. Under the joint restraint of the limiting hand ring and the positioning block, the first mounting plate, the second mounting plate, and the third mounting plate are kept fixed, thus completing the assembly of the hopper. When disassembling the hopper, the sliding rod is rotated to make the positioning block and the sliding rod fully correspond to the hole. The sliding rod is pulled outward to pull it out from the second and third mounting plates, thus completing the disassembly of the plate unit and the frame, improving the convenience of hopper assembly and disassembly.
[0015] Optionally, the fixing member further includes a first spring for driving the sliding rod away from the second and third mounting plates.
[0016] By adopting the above technical solution, when disassembling and transferring the hopper, rotating the sliding rod makes the positioning block and the sliding rod and the hole completely correspond. Under the action of the first spring, the sliding rod is pushed to move away from the first mounting plate and the second mounting plate, completing the disassembly between the plate unit and the frame, and further improving the convenience of hopper installation and disassembly.
[0017] Optionally, the fixing component further includes a housing and a slider; the housing is fixedly connected to the first mounting plate, the sliding rod passes through the housing and slides with the housing; the slider is disposed inside the housing and fixedly connected to the sliding rod, and slides with the housing; the first spring is sleeved on the sliding rod, and the two ends of the first spring elastically abut against the sliding rod and the end of the housing near the positioning block, respectively.
[0018] By adopting the above technical solution, the guide rod can restrict and guide the extension and retraction of the first spring, thereby improving the smoothness of the extension and retraction of the first spring.
[0019] Optionally, a sliding groove is provided on the inner wall of the outer shell along the sliding direction of the sliding rod, and an arc-shaped slot is provided along the rotation direction of the sliding rod. The end of the slider away from the sliding rod is located in the slot and slides with the slot. The slot and the end of the sliding groove away from the limiting wristband are connected.
[0020] By adopting the above technical solution, the slide can restrict and guide the slider, thereby limiting the rotation of the sliding rod and keeping the positioning block in a relatively fixed position, which facilitates the installation of the frame on the base plate. When the positioning block completely passes through the second mounting plate and the third mounting plate, the position of the slider corresponds to the slot. When the sliding rod is rotated, the positioning block rotates and is misaligned with the holes on the second mounting plate and the third mounting plate, thereby fixing the first mounting plate, the second mounting plate and the third mounting plate.
[0021] Optionally, the silo is detachably connected with multiple partitions, which are arranged along the length of the silo and are lower than the height of the frame, dividing the silo into multiple casting sections.
[0022] By adopting the above technical solution, during pouring, pouring can start from the uppermost pouring section. When the amount of concrete is higher than the height of the partition, the concrete will flow to the next pouring section, achieving the purpose of pouring in batches. The partition can allow the concrete to have a reserve in each pouring section, reducing the problem of the concrete flowing downward due to gravity, which makes it difficult to pour into the upper grouting hole.
[0023] Optionally, a scraper is slidably connected inside the hopper, with its two sides abutting against the two side walls opposite to the frame, and its bottom elastically abutting against the bottom plate; a discharge port is provided at one end of the hopper, and a sealing cap is provided on the discharge port.
[0024] By adopting the above technical solution, after the pouring is completed, the partition is removed, and the remaining raw material flows out from the outlet under gravity. Then, the scraper is pushed towards the outlet to clean up the residue. This improves the convenience of cleaning residual materials in the silo.
[0025] Optionally, sliders are slidably connected to both sides of the hopper, and mounting plates are provided on the sliders. The scraper is connected to the mounting plate through an elastic element. The elastic element includes a guide rod and a second spring. The guide rod passes through the mounting plate and slides with the mounting plate. The end of the guide rod is fixedly connected to the side of the scraper away from the bottom plate. The second spring is sleeved on the guide rod and its two ends elastically abut against the scraper and the mounting plate, respectively.
[0026] By adopting the above technical solution, under the action of the second spring, the mounting plate is pushed to elastically abut against the base plate. The guide rod can restrict and guide the extension and retraction of the second spring and the sliding of the mounting plate, thereby improving the stability and smoothness of the extension and retraction of the second spring and the sliding of the mounting plate.
[0027] In summary, this application includes at least one of the following beneficial technical effects:
[0028] 1. By setting up silos and funnels, the accuracy and efficiency of concrete pouring are improved, and the waste of raw materials is reduced;

[0041] The following is in conjunction with the appendix Figure 2-7 This application will be described in further detail.
[0042] This application discloses a concrete pouring tool for steel ring fiberglass tube segments. To facilitate understanding of the pouring tool provided in this application, its application scenario is first explained. The pouring tool provided in this application is mainly used for pouring concrete into steel ring tube segments. In the prior art, grouting pumps and conduits are generally used to inject concrete one by one into the grouting holes on the surface of the steel ring tube segment, which easily causes concrete overflow, resulting in waste of raw materials and inconvenience for subsequent cleaning. Therefore, this application provides a concrete pouring tool for steel ring fiberglass tube segments to improve the accuracy and efficiency of concrete pouring. The concrete pouring tool for steel ring fiberglass tube segments provided in this application will be described below with reference to the accompanying drawings.
[0043] Reference Figure 2 The concrete pouring tool for steel ring fiberglass tube segments mainly includes a hopper 2 and a funnel 3. The shape of the hopper 2 is adapted to the shape of the steel ring fiberglass tube segment 1 and can at least completely cover the grouting holes 10 on the steel ring fiberglass tube segment 1. The funnel 3 is set at the bottom of the hopper 2 and communicates with the hopper 2. There are multiple funnels 3, and their number and position correspond to the grouting holes 10 on the steel ring fiberglass tube segment 1. Before pouring, the funnel 3 is inserted into the grouting hole 10, and the outer wall of the funnel 3 abuts against the opening of the grouting hole 10 and seals the grouting hole 10. When pouring concrete, the hopper 2 acts as an intermediate transition, which can receive the concrete and, through the funnel 3, ensure that the concrete is accurately poured into each grouting hole 10, reducing the waste of raw materials.
[0044] Reference Figure 3The hopper 2 includes an arc-shaped base plate 20 and a frame 21 detachably connected to the base plate 20. The base plate 20 includes multiple interlocking and detachable plate units. When storing and transferring the hopper 2, the frame 21 can be disassembled first, and then the plate units can be disassembled to facilitate the transfer and storage of the hopper 2. Specifically, the plate units and the base plate 20 and the frame 21 can be fixed with screws, bolts, or pins. In this embodiment, a fastener 4 is provided between the base plate 20 and the frame 21, which can simultaneously fix the plate units and the plate units to the frame 21.
[0045] Reference Figure 3 and Figure 4 A first mounting plate 210 protrudes from the outer side of the frame 21, and a second mounting plate 200 and a third mounting plate 201 protrude from adjacent two plate units respectively. When the plate units are spliced together and the frame 21 is installed on the base plate 20, the first mounting plate 210, the second mounting plate 200 and the third mounting plate 201 are in a state of mutual contact, and the fastener 4 is provided on the first mounting plate 210.
[0046] Reference Figure 5 The fixing component 4 includes a housing 40, a sliding rod 41, a positioning block 42, a limiting wrist ring 43, a slider 44, and a first spring 45. The housing 40 is fixedly connected to the first mounting plate 210, specifically, it can be welded or threaded. The sliding rod 41 passes through the housing 40 and slides with the housing 40. One end of the sliding rod 41 passes through the surface of the first mounting plate 210, and the other end is located outside the housing 40. The sliding rod 41 can rotate around its own axis. The positioning block 42 protrudes from the side of the portion of the sliding rod 41 that passes through the first mounting plate 210. The limiting wrist ring 43 is fixedly connected to the end of the sliding rod 41 away from the positioning block 42.
[0047] Reference Figure 5 and Figure 6 The second mounting plate 200 has a first fixing hole 202 that penetrates the plate surface, and the third mounting plate 201 has a second fixing hole 203 that penetrates the plate surface. The shapes of the first fixing hole 202 and the second fixing hole 203 are adapted to the shape formed by the sliding rod 41 and the positioning block 42. When fixing the plate unit and the frame 21, the sliding rod 41 is pressed to make the sliding rod 41 pass through the first fixing hole 202 and the second fixing hole 203. Then the sliding rod 41 is rotated to make the positioning block 42 misalign with the first fixing hole 202 and the second fixing hole 203. Under the combined action of the limiting hand ring 43 and the positioning block 42, the first mounting plate 210, the second mounting plate 200 and the third mounting plate 201 are kept in a fixed state.
[0048] The slider 44 is disposed inside the housing 40 and fixedly connected to the sliding rod 41, and the slider 44 slides in cooperation with the housing 40; the first spring 45 is sleeved on the sliding rod 41 and its two ends abut against the slider 44 and the end of the housing 40 away from the limiting wristband 43, respectively. The first spring 45 is in a compressed state, thereby pushing the sliding rod 41 to drive the positioning block 42 to move toward the housing 40; improving the stability and ease of disassembly of the first mounting plate 210, the second mounting plate 200 and the third mounting plate 201.
[0049] The housing 40 has a sliding groove 400 along the sliding direction of the sliding rod 41, and an arc-shaped slot 401 along the rotation direction of the sliding rod 41. The slot 401 is connected to the end of the sliding groove 400 away from the limiting wristband 43. The end of the slider 44 away from the sliding rod 41 is located in the slot 401 and slides with the slot 401, thereby facilitating the positioning of the positioning block 42 and improving the ease of installation.
[0050] Reference Figure 3 and Figure 6 One side of the plate unit has a protruding overlapping edge 204, and the other side has an overlapping groove 205. When two adjacent plate units are spliced together, the overlapping groove 205 and the overlapping edge 204 cooperate with each other, thereby improving the sealing performance at the connection of the plate units. A sealing groove 206 is formed around the bottom plate 20. When the frame 21 is fixed to the bottom plate 20, the bottom side of the frame 21 is inserted into the sealing groove 206, thereby improving the sealing performance between the frame 21 and the bottom plate 20.
[0051] Reference Figure 2 The silo 2 is detachably connected to multiple partitions 5. The partitions 5 are arranged along the length of the silo 2 and are lower than the height of the frame 21, dividing the silo 2 into multiple pouring sections. During pouring, pouring can begin from the uppermost section. When the amount of concrete exceeds the height of the partitions 5, the concrete flows to the next pouring section, achieving the purpose of batch pouring. The partitions 5 allow for a reserve of concrete within each pouring section, reducing the problem of concrete flowing downwards due to gravity, which makes it difficult to pour into the upper grouting holes 10. Specifically, multiple sets of limiting grooves 211 are formed along the height direction on the inner walls of opposite sides of the frame 21. The partitions 5 are inserted into the limiting grooves 211 and slide in cooperation with them, facilitating the installation and removal of the partitions 5. In another embodiment, only one partition 5 can be provided, and the position of the partition 5 within the silo 2 can be manually changed to achieve the purpose of batch pouring.
[0052] Reference Figure 3 and Figure 7To facilitate the cleaning of residual material in silo 2, a scraper 6 is installed inside silo 2. The scraper 6 slides along the length of silo 2 and is connected to silo 2. The two sides of the scraper 6 abut against the two side walls opposite to the frame 21, and the bottom of the scraper 6 elastically abuts against the bottom plate 20. A discharge port 212 is opened at the lower end of the frame 21, and a sealing cap 213 is threaded onto the discharge port 212. After the pouring is completed, the partition 5 is removed, and the remaining raw material flows out from the discharge port 212 under the action of gravity. Then, the scraper 6 is pushed towards the discharge port 212 to clean up the residual material.
[0053] Specifically, a sliding block 7 is slidably connected to each of the opposite sides of the frame 21. The sliding block 7 has a sliding groove 70, and the sidewall of the frame 21 is clamped within the sliding groove 70. A slide rail 214 protrudes along the length of the frame 21, and a groove 71 is provided within the sliding groove 70. The slide rail 214 is embedded in the groove 71 and slides in cooperation with it. Through the cooperation of the slide rail 214 and the groove 71, the sliding block 7 is constrained on the frame 21. A fixing plate 8 is fixedly connected to the sliding block 7. The fixing plate 8 is connected to the scraper 6 via an elastic element 9, thereby allowing the scraper 6 to elastically abut against the base plate 20.
[0054] Reference Figure 7 The elastic element 9 includes a guide rod 90, a second spring 91, and a limiting ring 92. The guide rod 90 passes through the fixed plate 8 and slides with the fixed plate 8. The bottom end of the guide rod 90 is fixedly connected to the side of the scraper 6 away from the bottom plate 20. The second spring 91 is sleeved on the guide rod 90 and its two ends abut against the scraper 6 and the fixed plate 8 respectively. The second spring 91 is always in a compressed state, thereby pushing the scraper 6 and the bottom plate 20 to elastically press together. The limiting ring 92 is fixedly connected to the end of the guide rod 90 away from the scraper 6, thereby restricting the guide rod 90 and preventing the guide rod 90 from separating from the fixed plate 8 when the frame 21 is disassembled. Specifically, the limiting ring 92 is threadedly connected to the guide rod 90.
[0055] The implementation principle of a concrete pouring tool for steel ring fiberglass tube segments according to an embodiment of this application is as follows: Before pouring, the hopper 2 is placed on the steel ring fiberglass tube segment 1, and the funnel 3 is inserted into multiple grouting holes 10 accordingly. The outer wall of the funnel 3 abuts against the opening of the grouting hole 10 and seals the grouting hole 10. The pouring device is used to pour concrete into the uppermost pouring section. When the amount of concrete is higher than the height of the partition 5, the concrete will flow to the next pouring section, thereby allowing the concrete to be accurately poured into each grouting hole 10 through the funnel 3, reducing concrete overflow due to operational inaccuracies. Multiple grouting holes 10 can be poured simultaneously, avoiding concrete overflow caused by the transfer of pipes between grouting holes 10. When one grouting hole 10 is full, the excess concrete will remain in the hopper 2, further reducing concrete overflow. The partition 5 can achieve the purpose of batch pouring, so that there is a reserve of concrete in each pouring section, reducing the problem of concrete flowing downwards due to gravity, making it difficult to pour into the upper grouting holes 10.
[0056] After pouring, the discharge port 212 is opened, and the remaining material flows out from the discharge port 212 under the action of gravity. Then, the scraper 6 is pushed towards the discharge port 212 to clean up the residue. The elastic element 9 can keep the scraper 6 and the base plate 20 in an elastic and tight state, improving the cleaning effect. After cleaning, the sliding rod 41 is rotated so that the positioning block 42 and the sliding rod 41 are fully aligned with the first fixing hole 202 and the second fixing hole 203. The slider 44 then enters the slide groove 400 from the slot 401. Under the action of the first spring 45, the sliding rod 41 is pushed to move away from the first mounting plate 210 and the second mounting plate 200 and exits from the first mounting plate 210 and the second mounting plate 200. At the same time, the plate unit and the frame 21 are disassembled. Then, the plate unit and the frame 21 are transferred to another steel ring glass fiber tube sheet 1 for assembly.
[0057] First, the splicing plate unit is assembled, with the overlapping edge 204 and overlapping groove 205 engaging with each other. Then, the frame 21 is inserted into the sealing groove 206 from above. At this time, the first mounting plate 210, the second mounting plate 200, and the third mounting plate 201 are in an overlapping state. Since the sliding groove 400 has a limiting effect on the slider 44, the positioning block 42 can be kept in a relatively fixed position, which facilitates the positioning block 42 to be positioned with the first fixing hole 202 and the second fixing hole 203. Press down the limiting wristband 43, and the sliding rod 41 connects... Simultaneously, the positioning block 42 passes through the first fixing hole 202 and the second fixing hole 203. The slider 44 slides within the outer casing 40, compressing the first spring 45. When the positioning block 42 completely passes through the second mounting plate 200 and the third mounting plate 201, the position of the slider 44 corresponds to the slot 401. Rotating the sliding rod 41 causes the positioning block 42 to rotate and misalign with the holes on the second mounting plate 200 and the third mounting plate 201, thereby fixing the first mounting plate 210, the second mounting plate 200, and the third mounting plate 201. The assembly of the hopper 2 is then complete. In summary, by setting up the hopper 2 and the funnel 3, the accuracy and efficiency of concrete pouring are improved, and the waste of raw materials is reduced.
[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
