Description

Technical Field

[0001] This application relates to the field of tunnel construction equipment, and in particular to tunnel lining construction trolleys and tunnel lining construction methods. Background Technology

[0002] The construction and development of tunnel engineering has greatly promoted the development of my country's transportation industry. In the process of tunnel excavation, tunnel lining construction is usually used. It is a construction method of building tunnels by excavating underground tunnels. In order to reinforce the surrounding rock and form a tunnel structure system with sufficient safety together with the surrounding rock to jointly bear various possible loads, the lining is also called the support structure.

[0003] In related technologies, application document CN205243529U discloses a tunnel lining construction trolley, including: a trolley support system and a trolley formwork system; the trolley support system includes: a support system frame, a vertical hydraulic device, an upper upright, a horizontal hydraulic device, and a horizontal bar; the trolley formwork system includes: a formwork system frame, a lifting hydraulic cylinder, longitudinal beams, chords, and formwork adjusting screws. The trolley support system enables a temporary support system that can break through the central diaphragm and invert arch in one go. After the trolley support system is assembled, the formwork needs to be installed. All the formwork adjusting screws are turned out, and the formwork position is adjusted to make it fit tightly. Then, grouting is performed, and the concrete is vibrated by a vibrating device. After the concrete reaches the design strength requirements, the formwork is demolded.

[0004] Regarding the aforementioned technologies, after the trolley support system is assembled, templates need to be installed, their positions adjusted to ensure a tight fit, followed by grouting, vibration, and demolding. However, when installing the templates, personnel need to start from the middle and work outwards to check if the height of each chord meets the design requirements before installing the remaining templates. This results in a long installation time and makes the installation operation quite troublesome. Summary of the Invention

[0005] To address the issue of cumbersome installation and operation, this application provides a tunnel lining construction trolley and a tunnel lining construction method.

[0006] The tunnel lining construction trolley and tunnel lining construction method provided in this application adopt the following technical solutions: A tunnel lining construction trolley includes a translation component, multiple drive components, and a support component. The translation component includes a top translation plate and multiple middle translation plates, both of which are horizontally arranged. The multiple middle translation plates are located below the top translation plate. The top translation plate and the multiple middle translation plates form a stepped shape symmetrical about a central axis perpendicular to the top translation plate. The multiple middle translation plates are divided into multiple layers, with two middle translation plates in each layer. One top translation plate corresponds to three driving components, and one middle translation plate corresponds to one driving component. The driving component located on the top translation plate is connected to the top translation plate, and the driving component located on the middle translation plate is connected to the middle translation plate. The support component includes multiple arc-shaped plates, one arc-shaped plate corresponds to one driving component, the opening of the arc-shaped plate faces the side of the driving component, the driving component is connected to the arc-shaped plate to drive the arc-shaped plate to move, two adjacent arc-shaped plates fit together, and a pouring gap is left between the arc-shaped plate and the inner wall of the tunnel.

[0007] By adopting the above technical solution, when a tunnel lining construction trolley is needed, the tunnel floor slab must first be constructed in sections, with the steel grating reinforcement embedded inside the invert arch secondary lining. Waterproof membrane is then laid in sections along the tunnel's forward direction, followed by the binding and pouring of the floor slab reinforcement. The tunnel lining construction trolley is then moved to a suitable position, ensuring the top and multiple middle sliding plates are horizontal, and the trolley is secured. Next, the drive assembly on the top sliding plate is activated, driving the curved plate towards the tunnel wall. Once the curved plate reaches the desired position, the drive assembly is deactivated, leaving a pouring gap between the curved plate and the tunnel wall. Then, the drive assemblies on the remaining middle sliding plates are activated until the curved plate is adjusted... Once the two adjacent curved plates are aligned at the appropriate position, concrete is poured into the gap between them. After pouring, a vibratory compactor is used to compact the concrete. After the concrete has solidified, the curved plates are continuously tapped to loosen them. The drive assembly is then activated to retract the curved plates. This process is repeated until the tunnel construction is complete. Compared with related technologies, this application moves the tunnel lining construction trolley to the appropriate position, adjusts the curved plates to the appropriate position by activating the drive assembly located on the top sliding plate, and then activates the remaining drive assemblies to adjust the curved plates to the correct position, ensuring that the two adjacent curved plates are aligned. Personnel only need to observe whether the curved plates have reached the designated position, which facilitates the installation of the curved plates and helps to improve the problem of cumbersome installation operations.

[0008] Optionally, the translation assembly further includes multiple support members and multiple sliding members. Four support members are vertically fixed at the bottom of the top translation plate. The four support members are arranged in a matrix. Each support member is located near a corner of the top translation plate. Two support members near the same middle translation plate are slidably connected to the middle translation plate at the ends away from the top translation plate. Two support members are vertically fixed at the bottom of each middle translation plate. The lower middle translation plate is slidably connected to the support members at the bottom of the upper middle translation plate. Two middle translation plates located on the same layer move toward or away from each other. One of the sliding members corresponds to one of the central translation plates, the sliding member is connected to the central translation plate, and the sliding member is connected to the support member to drive the central translation plate to move.

[0009] By adopting the above technical solution, when a tunnel lining construction trolley is needed, firstly, the trolley is moved to a suitable position and leveled. Then, depending on the tunnel diameter, multiple sliding components are activated simultaneously. These components drive the central translation plate to move. At this time, two central translation plates on the same level move towards each other. During the movement of the central translation plate, personnel continuously observe until it is moved to the appropriate position. Then, the sliding components are deactivated. Subsequently, the drive assembly is activated, which drives the arc-shaped plate to move until a pouring gap is left between the arc-shaped plate and the tunnel wall. When it is necessary to remove the arc-shaped plate, the sliding components can be activated first. The movement of two central sliding plates on the same level towards each other allows the curved plate to separate from the tunnel wall. This is useful when the tunnel lining construction trolley moves to the next section to continue construction. By incorporating sliding components, the central sliding plates can be moved. This facilitates construction on tunnels of different diameters. Furthermore, when the curved plate needs to be removed, simply activating the sliding components will move the two central sliding plates on the same level, separating them from the concrete. For the next tunnel section, the sliding components can move the two central sliding plates away from each other without needing to reactivate the drive assembly, further simplifying the previously cumbersome installation process.

[0010] Optionally, each of the shorter side walls of the arc-shaped plate located in the middle of the top sliding plate has at least one slot, the slot being close to the opening side of the arc-shaped plate. At least one insert is fixed to one of the shorter side walls of the remaining arc-shaped plates, the insert fitting into the slot. The other shorter side wall of the arc-shaped plate has a slot for inserting the insert on the adjacent arc-shaped plate.

[0011] By adopting the above technical solution, firstly, when the drive component located in the middle of the top sliding plate is activated, the drive component drives the arc plate to move to a suitable position. Then, the drive components located on both sides of the top sliding plate are activated, so that the inserts on the arc plates on both sides of the top sliding plate can engage with the slots on the arc plate located in the middle of the top sliding plate. Following the above steps, the remaining drive components are activated to engage the inserts and slots on two adjacent arc plates. By setting the engagement of the inserts and slots, on the one hand, the stability of the connection between two adjacent arc plates can be increased; on the other hand, it is convenient to install two adjacent arc plates.

[0012] Optionally, the support assembly further includes multiple support plates, one support plate corresponding to one arc-shaped plate, the support plate being fixed to one side of the opening of the arc-shaped plate, and the support plate being located in the middle of the arc-shaped plate; The drive assembly includes a first cylinder, with the first cylinders located on both sides of the top translation plate tilted away from each other, the first cylinder located in the middle of the top translation plate being vertically arranged, and the remaining first cylinders being symmetrical about the axis of the piston rod of the first cylinder located in the middle of the top translation plate. The cylinder body of the first cylinder is fixed to the top translation plate, and the piston rod of the first cylinder is rotatably connected to the support plate. The tunnel lining construction trolley also includes multiple adjustment components, one of which corresponds to one of the support plates. The adjustment component is connected to the support plate to drive the support plate to rotate in a direction perpendicular to the axis of the first cylinder piston rod.

[0013] By adopting the above technical solution, when a tunnel lining construction trolley is needed, after moving the trolley to a suitable position, firstly, multiple adjustment components are activated. These components drive the support plate to rotate. During the rotation of the support plate, the arc-shaped plate rotates synchronously with it. Personnel continuously observe until the arc-shaped plate is adjusted to the appropriate position. At this point, multiple first cylinders are activated sequentially according to a specified order. These first cylinders push the support plate to move, thereby adjusting the arc-shaped plate to the appropriate position, leaving a pouring gap between the arc-shaped plate and the tunnel wall. After that, personnel can pour concrete. Once the concrete has solidified, the first cylinder is activated again, driving the arc-shaped plate to move away from the tunnel wall. By setting up the first cylinder, the movement of the arc-shaped plate is automated, facilitating personnel operation.

[0014] Optionally, the sliding component includes two racks, two gears, a rotating rod, and a drive source. Two grooves are formed on the side of the central translation plate near the support member it is slidably connected to. One support member corresponds to one groove, and the grooves are formed by one central translation plate facing the other. One rack corresponds to one groove, and the rack's orientation is consistent with the groove's orientation. The rack slides within the groove along the groove's orientation. The support member is fixed to the rack. One gear corresponds to one rack, and the gear can extend into the groove and mesh with the rack. The rotating rod is horizontally positioned, and its orientation is perpendicular to the groove's orientation. Each end of the rotating rod is close to one of the grooves. The rotating rod is rotatably connected to the central translation plate. The gears are coaxially fixed to the rotating rod. The drive source is connected to the central translation plate and to the rotating rod to drive the rotating rod to rotate.

[0015] By adopting the above technical solution, when it is necessary to move the middle translation plate on the same floor, two drive sources located on the same floor are activated simultaneously. The drive sources drive the rotating rod to rotate. During the rotation of the rotating rod, the gear located on the rotating rod can rotate with the rotating rod. At this time, the gear can drive the rack to move. During the movement of the rack, the support component moves synchronously with the rack, which can make the middle translation plates on the same floor move towards or away from each other. By setting the cooperation between the rack and the gear, it is beneficial to drive the movement of the middle translation plate and facilitates personnel operation.

[0016] Optionally, the translation assembly further includes multiple telescopic components, with one telescopic component corresponding to each of the middle translation plates on the same layer. Each telescopic component includes multiple first telescopic rods, all of which are horizontally arranged. The first telescopic rods are arranged from one of the middle translation plates to another, and are located between the two middle translation plates. The distribution direction of the multiple first telescopic rods is perpendicular to the central axis direction of the top translation plate.

[0017] By adopting the above technical solution, when the two middle translation plates of the same layer move away from each other, the first telescopic rod extends; when the two middle translation plates of the same layer move closer to each other, the first telescopic rod shortens. By setting the first telescopic rod, on the one hand, it is beneficial to increase the connection between the two middle translation plates of the same layer, thereby enhancing the stability of the tunnel lining construction trolley; on the other hand, personnel can stand on the first telescopic rod to carry out construction, thereby increasing the range of movement of personnel on the construction trolley.

[0018] Optionally, the telescopic component further includes multiple vertical rods, with one first telescopic rod corresponding to at least one of the vertical rods. The vertical rods are vertically arranged, with one end connected to the upper first telescopic rod and the other end connected to the lower first telescopic rod. The vertical rods are used to support the upper and lower first telescopic rods.

[0019] By adopting the above technical solution, when the first telescopic rod extends to a suitable position, the vertical rod is connected to the upper first telescopic rod and the lower first telescopic rod. By setting the vertical rod, it is beneficial to increase the connection between the upper first telescopic rod and the lower first telescopic rod.

[0020] Optionally, each of the arc-shaped plates is provided with a grouting port, which penetrates the arc-shaped plate along the thickness direction. A grouting plate is installed on the arc-shaped plate at the grouting port, which is used to close the grouting port and fits into the arc-shaped plate.

[0021] By adopting the above technical solution, when the arc-shaped plate is adjusted to a suitable position, personnel open the grouting plate located at the bottom layer and inject grout between the arc-shaped plate and the inner wall of the tunnel through the grouting port. When the grouting reaches the grouting port, the grouting plate is closed, and then the grouting plate above it is opened to continue grouting. The above operation is repeated until the pouring is completed. By setting up the grouting port and grouting plate, it is convenient to pour concrete.

[0022] Optionally, it also includes two moving components located below the lowest central sliding plate. Each moving component corresponds to one central sliding plate. Each moving component includes four casters, all of which are connected to the bottom of the central sliding plate and are arranged in a matrix.

[0023] By adopting the above technical solution, when personnel push the tunnel lining construction trolley, the casters move with the tunnel lining construction trolley, and by setting the casters, it is easy to move the tunnel lining construction trolley.

[0024] Optionally, a method for constructing tunnel lining by cut-and-cover method includes the following steps: S1: The tunnel floor needs to be constructed in sections, and the steel grating reinforcement should be embedded inside the invert arch lining. Waterproof membrane should be laid in sections along the tunnel's forward direction, and the floor reinforcement should be tied and poured. S2: Move the tunnel lining construction trolley to a suitable position and make it horizontal; S3: Activate the sliding component in the translation assembly to form a stepped shape with the top translation plate and multiple middle translation plates; S4: Activate the drive component located in the middle of the top sliding plate to adjust the support component to the appropriate position, and then adjust the remaining support components to the appropriate position; S5: Concrete pouring begins; S6: After the concrete has solidified, activate the drive and adjustment components to separate the arc plate from the tunnel wall.

[0025] By adopting the above technical solution, when a tunnel lining construction trolley is needed, it is moved to a suitable position and leveled. Then, according to the size of the tunnel diameter, the sliding component in the translation assembly is activated, followed by the drive assembly located in the middle of the top translation plate. This adjusts the support assembly to a suitable position. Then, the drive assemblies on both sides are activated in sequence to adjust the remaining support assemblies to a suitable position. After that, concrete can be poured. Once the concrete has solidified, the arc-shaped plate can be removed using the drive assembly, making it easy for personnel to operate.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. Compared with related technologies, this application moves the tunnel lining construction trolley to a suitable position, and then adjusts the arc plate to a suitable position by activating the drive assembly located on the top sliding plate rod. Then, the remaining drive assemblies are activated to adjust the arc plate to the position, so that two adjacent arc plates fit together. Personnel only need to observe whether the arc plate has reached the designated position, which facilitates the installation of the arc plate and helps to improve the problem of the relatively troublesome installation operation. 2. By setting up sliding components, the sliding components can drive the movement of the central translation plate. On the one hand, this is beneficial for adapting to the construction of tunnels with different diameters; on the other hand, the sliding components can drive the two central translation plates on the same level to move away from each other, and the arc rod separates from the concrete. There is no need to restart the drive assembly, which further helps to improve the problem of complicated installation operations. 3. By setting the first telescopic rod, on the one hand, it is beneficial to increase the connection between the two middle sliding plates on the same layer, thereby enhancing the stability of the tunnel lining construction trolley; on the other hand, personnel can stand on the first telescopic rod to carry out construction, thereby increasing the range of movement of personnel on the construction trolley.

The rotary motor 52 can drive the support plate 42 to rotate in a direction perpendicular to the axis of the piston rod of the first cylinder 31.

[0040] The implementation principle of the tunnel lining construction trolley in this application embodiment is as follows: When the tunnel lining construction trolley is required, the bottom slab of the tunnel needs to be constructed in sections, and the steel grid reinforcement is embedded inside the invert arch secondary lining. Waterproof membrane is laid in sections along the tunnel's forward direction, and the bottom slab reinforcement is tied and poured. Then, the tunnel lining construction trolley is moved to a suitable position and placed in a horizontal state. Then, according to the size of the tunnel diameter, the sliding component 14 in the translation component 1 is activated to move the middle translation plate 12 to a suitable position, so that the top translation plate 11 and multiple middle translation plates 12 form a step shape. Then, the drive component 3 located in the middle of the top translation plate 11 is activated to adjust the support component 4 to a suitable position. Then, the drive components 3 located on both sides are activated in sequence to adjust the remaining support components 4 to a suitable position. After that, concrete is poured. After the concrete solidifies, the support components 4 can be removed.

[0041] When the support assembly 4 needs to be adjusted to a suitable position, firstly, the drive assembly 3 located in the middle of the top translation plate 11 is activated. The first cylinder 31 adjusts the arc plate 41 to a suitable position. Then, the remaining first cylinders 31 are activated in sequence to allow the insert 412 on the arc plate 41 to be inserted into the slot 411 until the arc plate 41 is adjusted. Then, the grouting plate 414 located at the bottom arc plate 41 is opened to inject grout between the arc plate 41 and the inner wall of the tunnel. When the grouting reaches the grouting port 413, the grouting plate 414 is closed, and the grouting plate 414 above it is opened to continue grouting. The above operation is repeated until the pouring is completed. After the concrete has solidified, the arc plate 41 is separated from the concrete.

[0042] When it is necessary to separate the curved plate 41 from the concrete, firstly, personnel climb onto the middle sliding plate 12 and continuously tap the lowermost curved plate 41 to loosen it. Then, the first cylinder 31 is activated, which pulls the curved plate 41 away from the tunnel wall. Once it reaches the appropriate position, the adjustment component 5 is activated to rotate the curved plate 41 by a certain angle. Following the above steps, the remaining curved plates 41 can be removed.

[0043] A method for tunnel lining construction using the cut-and-cover method includes the following steps. S1: The tunnel floor needs to be constructed in sections, and the steel grating reinforcement should be embedded inside the invert arch lining. Waterproof membrane should be laid in sections along the tunnel's forward direction, and the floor reinforcement should be tied and poured. S2: Move the tunnel lining construction trolley to a suitable position and make it horizontal; S3: Activate the sliding component 14 in the translation assembly 1 to form a stepped shape with the top translation plate 11 and multiple middle translation plates 12; S4: Activate the drive component 3 located in the middle of the top sliding plate 11 to adjust the support component 4 to the appropriate position, and then adjust the remaining support components 4 to the appropriate position. S5: Concrete pouring begins; S6: After the concrete has solidified, start the drive assembly 3 and the adjustment assembly 5 to separate the arc plate 41 from the tunnel wall.

[0044] 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.
