Description

[Technical Field]

[0001] The present invention relates to a concrete pouring system for tunnels, and more particularly to a concrete pouring system for tunnels that forms a reinforced concrete tunnel roadbed in a railway tunnel through which railway trains pass. [Background technology]

[0002] Concrete pouring systems for tunnels, particularly for forming reinforced concrete tunnel roadbeds in railway tunnels, involve pouring concrete in the enclosed, narrow space of the tunnel, making it difficult to use, for example, boom pump trucks used for outdoor concrete pouring.

[0003] For this reason, in the past, the bucket part of the backhoe was changed to a hopper for ready-mixed concrete, and ready-mixed concrete was poured into this hopper from an agitator vehicle, and the hopper was then moved to the designated pouring position and transported out.

[0004] However, in the past, the work required repeated loading of concrete into a concrete hopper and moving and unloading the hopper, which lengthened the construction time. Furthermore, because the loading, moving and unloading of ready-mixed concrete was carried out near workers engaged in compaction and trowel finishing work, there was a high possibility that the workers would come into contact with the backhoe as it moved and turned, which was an issue.

[0005] To address this issue, a method of pouring concrete using a piping trolley was proposed (Patent Publication No. 2010-229761). However, although this method increased safety, it was not primarily designed for rapid pouring, and so the construction time was extremely long.

[0006] On the other hand, the so-called slip form method (reinforced concrete roadbed slip form method) has also been proposed, but this method has the problem that a large number of people are required to set up the formwork and move the pouring machine, and the pouring work is greatly affected by the hardness of the concrete and the pump pressure. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-229761 Summary of the Invention [Problem to be solved by the invention]

[0008] The present invention was devised to solve the above-mentioned conventional problems, and aims to provide a concrete pouring system for reinforced concrete tunnels, such as railway tunnels, that does not require long construction times, eliminates the possibility of contact between workers engaged in compacting the poured concrete or trowel finishing work and the pouring equipment, and does not require a large number of people to set up the formwork or move the pouring machine, and does not cause the pouring work to be significantly affected by the hardness or softness of the concrete or the pump pressure.

[0009] In other words, the present invention utilizes a so-called swivel distributor as a concrete pouring facility and method, and provides a concrete pouring system for a reinforced concrete tunnel, such as a railway tunnel, in which the distributor is linearly integrated with a concrete pump, a generator, a self-propelled device, etc.

[0010] Furthermore, even in a narrow, enclosed space such as a railway tunnel, the use of the swivel distributor makes it possible to easily move the nozzle of the concrete discharge nozzle to the desired pouring position without contacting the tunnel wall.

[0011] In addition, because the distributor is a swivel type, it can be controlled and operated by a control device, and in emergencies such as when electricity is unavailable, it can also be swiveled and rotated by hand, reducing the risk of serious accidents due to contact compared to conventional backhoes.Furthermore, the discharge pipe tip can be moved by motor drive or automatically controlled by a control device, and because it is a so-called distributor type concrete pour, continuous pouring is possible, allowing for rapid construction.

[0012] On the other hand, by integrating various equipment into a linear pouring system, there is no need to extend or switch the piping between the concrete pump and the distributor-shaped discharge pipe, eliminating the time and effort required for switching.Furthermore, by connecting and self-propelling the vibrators and inverter equipment used for concrete compaction, as well as lighting fixtures and other equipment required for pouring work, and generators to serve as power sources, the labor required for work preparation can also be reduced.

[0013] Furthermore, it is possible to control the rotation of the distributor-shaped discharge pipe, as well as the movement and setting of the position of the discharge pipe tip, using a remote control or a computer that acts as a control device.In addition, by combining this with the use of sensors such as a laser rangefinder and LiDAR to grasp the current pouring situation, the overall work status can be recognized. In this way, automatic control of the discharge pipe tip and concrete discharge conditions is possible, making it possible to reduce labor and manpower. [Means for solving the problem]

[Figure 7] 1 is a flow chart illustrating the flow of a concrete pouring system in a tunnel according to the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0017] The present invention will now be described with reference to the embodiments shown in the drawings. 1 to 3 are schematic diagrams illustrating the configuration of one embodiment of the present invention.

[0018] 1 to 3, a tunnel roadbed forming portion 6 is formed in a tunnel 1 such as a railway tunnel to form a tunnel roadbed that is, for example, a substantially plate-shaped rectangular parallelepiped extending in the longitudinal direction of the tunnel 1. As can be seen from FIGS. 1 and 3, the tunnel roadbed forming portion 6 is provided in the tunnel 1, close to one side in the width direction. FIG. 1 shows the tunnel roadbed forming portion 6 close to the upper side. Railway rails are usually laid on the formed tunnel roadbed.

[0019] Here, the tunnel roadbed forming portion 6 is formed by laying a formwork 29 surrounding the tunnel roadbed in a substantially rectangular shape and arranging reinforcing bars inside the formwork. Concrete is then poured into the tunnel roadbed forming portion 6 to form the tunnel roadbed.

[0020] Then, a pouring device 2 is placed along the tunnel roadbed forming section 6 at a position near the width of the formed tunnel roadbed forming section 6 (a position near the bottom of the tunnel roadbed forming section 6 in Figure 1), and concrete is poured from the pouring device 2 into the tunnel roadbed forming section 6 to form the tunnel roadbed.

[0021] As shown in Figure 1, within the tunnel 1, not only the pouring device 2 but also a towing machine 7 consisting of a towing vehicle or the like, a generator 10, a concrete pump 8, etc. are connected in a straight line via a connecting bar 11, and are laid out and arranged so that concrete pouring work can be carried out smoothly even within the narrow tunnel 1. The pouring device 2, concrete pump 8, and generator 10 are each equipped with a means of transportation (wheels), and can be moved within the tunnel by being towed by the towing machine 7.

[0022] Reference numeral 9 denotes an agitator vehicle, and the produced concrete is sent from the agitator vehicle 9 to the concrete pump 8. However, the agitator vehicle 9 does not enter the tunnel 1.

[0023] The concrete pouring device 2 has a first discharge pipe 3 and a first discharge pipe 11 that discharge concrete sent from a concrete pump 8 into the tunnel roadbed forming portion 6.

[0024] Here, the base end of the first discharge pipe 3 is rotatably attached to the casting device 2 via a swivel device 5, and the other end of the first discharge pipe 3 is connected to a second discharge pipe 4 which is rotatably connected via the swivel device 5.

[0025] Furthermore, the length from the base end of the first discharge pipe 3 to the other end is set to a length such that the other end of the first discharge pipe 3, which is rotatably attached to the casting device 2, spans the width of the tunnel roadbed formation section 6 and the casting device 2 does not abut against the tunnel side wall 13 that faces in the width direction inside the tunnel.

[0026] This is because, as shown in Figure 1, by freely rotating the first discharge pipe 3, which is rotatable and has a length that does not hit the tunnel side wall 13, and the second discharge pipe 4, which is rotatable from the other end, left and right, concrete can be poured freely and steplessly in either the width direction or the length direction of the tunnel roadbed formation section 6.

[0027] Therefore, the length from the base end of the first discharge pipe 3 to the other end must be such that the casting device 2 does not come into contact with the opposing tunnel side wall 13 in the width direction of the tunnel.

[0028] The pouring device 2 is provided with a movable part 14 that operates the swiveling motion of the first discharge pipe 3 and the second discharge pipe 4, and for example, by manually operating the movable part 14 and controlling the swiveling motion of the first discharge pipe 3 and the second discharge pipe 4, it is possible to pour concrete freely and steplessly in the width and length directions of the tunnel roadbed forming section 6.

[0029] However, in this embodiment, a control device 15 is provided that can control the operation of the movable part 14 without manual operation. The control device 15 may be provided in the concrete pouring device 2, or may be a control device 15 that is installed in a different location and can control the movable part 14 by online operation.

[0030] Here, the rotation control of the first discharge pipe 3 and the second discharge pipe 4 in accordance with the control of the movable part 14 by the control device 15 will be described.

[0031] As shown in Fig. 4, the control device 15 is usually configured to have a receiving unit 16, a transmitting unit 17, a control unit 18, a memory unit 19, a display unit 20, and an input unit 21. As shown in Fig. 5, the control unit 18 is configured to have a first discharge pipe rotation control unit 22, a second discharge pipe rotation control unit 23, a pouring block range setting unit 24, a pouring block pouring recognition unit 24, and a compaction recognition unit 25.

[0032] First, the casting block range setting unit 24 sets multiple casting blocks 27, each approximately rectangular, e.g., 1 m wide x 1 m long, within the concrete roadbed formation section 6, which is a rectangular prism, e.g., 3 m wide and 15 m long, as shown in Figure 6.

[0033] Next, as can be seen from Figure 6, the plurality of casting blocks 27 are numbered 1, 2, 3, etc. from the left. The casting block range setting unit 24 sets the casting order so that concrete can be dispensed into the casting blocks 27 in the order of the numbers 1, 2, 3, etc.

[0034] The first discharge pipe rotation control unit 22 and the second discharge pipe rotation control unit 23 control the rotation of the first discharge pipe 3 and the second discharge pipe 4 so that the concrete can be discharged in the pouring order set by the pouring block range setting unit 24, i.e., in the order in which the concrete is attached to the pouring blocks 27.

[0035] To explain the rotation control in more detail, as shown in Figure 6(b), the first discharge pipe rotation control unit 22 and the second discharge pipe rotation control unit 23 operate the rotation device 5 provided at the base end of the first discharge pipe 3 and the rotation device 5 provided at the connection between the first discharge pipe 3 and the second discharge pipe 4, thereby controlling the discharge pipe tip of the second discharge pipe 4 to move into the pouring block 27 numbered 1.

[0036] However, such control is performed by the casting block range setting unit 24 of the control unit 18, which acquires numerical values ​​such as the position and size of the concrete roadbed forming unit 6 and the size and number of the multiple casting blocks 27 separated therein, and performs calculations based on these numerical values ​​to automatically move the discharge nozzle of the first discharge pipe 3 sequentially from casting block number 1 to casting block number 2 27. As described above, the control is performed by the first discharge pipe swivel control unit 22, the second discharge pipe swivel control unit 23 and the casting block range setting unit 24.

[0037] Next, the pouring height of each pouring block 27 can be set to, for example, 0.2 m. At this time, the height can be set and recognized by the amount of concrete poured into each pouring block 27. That is, as described above, if the pouring height of each pouring block 27 is set to 1 m wide x 1 m long, as shown in FIG. 3 When the concrete is discharged, the pouring height of each pouring block 27 can be recognized as approximately 0.2 m. This control is performed by the pouring recognition unit 25 of the pouring block.

[0038] Next, the vibrator 28 (see Figure 1) provided near the tip of the second discharge pipe 4 is lowered and inserted into the pouring block 27 into which the concrete has been discharged, and the concrete is compacted for a certain period of time, for example, 30 seconds.

[0039] Here, the lowering and raising operations of the vibrator 28 and the compaction of the concrete by the vibrator 28 for a certain period of time are also controlled by the control device 15 of the present invention.

[0040] That is, the compaction recognition unit 26 controls the lowering and raising of the vibrator 28 and the operation of the vibrator 28 for a certain period of time.

[0041] The concrete height is then measured and confirmed again using a laser rangefinder or LiDAR, and if it is as set, for example 0.2 m, the concrete will be dispensed into the next numbered pouring block 27, number 2.

[0042] The pouring height of the concrete surface is also confirmed by the pouring recognition unit 25 of the pouring block.

[0043] Figure 6(c) is a diagram showing the operation of discharging concrete into the casting block number 2 27, in which the first discharge pipe 3 and the second discharge pipe 4 are controlled by the first discharge pipe rotation control unit 22 and the second discharge pipe rotation control unit 23 to operate the two rotation devices 5 mentioned above, causing the discharge nozzle of the second discharge pipe 4 to move into the casting block number 2 27, thereby ensuring that concrete is discharged.

[0044] After that, the operation of the two swivel devices 5 to the casting block 27 numbered 3 is controlled, the subsequent dispensing of concrete, confirmation of the set height of the dispensed concrete, and confirmation of the compaction of the concrete are controlled, and then the system moves to the casting block 27 numbered 4, allowing the dispensing of concrete to be carried out continuously in succession.

[0045] FIG. 7 is a flow chart showing a control procedure for the first discharge pipe 3, the second discharge pipe 4, the vibrator 28, etc. according to the present invention.

[0046] First, the discharge tip of the second discharge pipe 4 is controlled to move to, for example, the casting block 27 numbered 1 (step 100). Such movement control is performed by rotating the first discharge pipe 3 and the second discharge pipe 4 using the two rotating devices 5 described above.

[0047] Next, a predetermined amount, for example 0.2 m, is poured into the number 1 pouring block 27.3 The concrete is then discharged (step 101). By discharging a predetermined amount of concrete, the set height of the concrete to be discharged can also be confirmed. After that, the vibrator 28 is lowered into the discharged concrete and compacted for a predetermined time, for example, 30 seconds (step 102).

[0048] After the compaction, the vibrator 28 is raised, and then the height of the compacted concrete surface is measured using a sensor or the like (step 103). The lowering and raising of the vibrator 28 and the setting of the operating time required for compaction are performed by the compaction recognition unit 26.

[0049] Then, it is confirmed whether the height is equal to or greater than the set value (step 104), and if the answer is YES, the first discharge pipe 3 and the second discharge pipe 4 are rotated to discharge concrete to the casting block 27 of the next number (step 100). If the answer is NO in step 104, concrete is discharged to the missing height and compacted (step 105). Thereafter, it is determined again in step 104 whether the height is equal to or greater than the set value, and if the height is equal to or greater than the set value, concrete is discharged to the casting block 27 of the next number (step 100).

[0050] Here, the control is performed using the control device 15, and predetermined values ​​are set in advance to automatically discharge concrete, etc., but for some operations, for example, it is also possible to use a remote control to rotate the first discharge pipe 3 and the second discharge pipe 4, and to adjust the discharge volume. [Industrial Applicability]

[0051] The present invention is not limited to concrete pouring systems for railway tunnels, but also includes concrete pouring systems for a variety of tunnels such as road tunnels and waterway tunnels, and also applies to invert concrete construction in addition to concrete roadbed reinforcing bar work.
