Description

Technical Field

[0001] The present invention relates to the technical field of shield machines, and particularly to a cast-in-place inverted arch construction system and a shield machine. Background Art

[0002] Cast-in-place inverted arch construction is an important part of shield machine tunnel operations. Specifically, cast-in-place inverted arch construction is a process of pouring materials such as concrete into a pre-designed inverted arch formwork at the construction site to form an inverted arch structure at the bottom of the tunnel. This inverted arch can enhance the bearing capacity of the tunnel bottom and improve the overall stability of the tunnel.

[0003] Currently, during the construction process of shield machine tunnels, in order to avoid interference between material transportation and inverted arch construction during tunneling, generally, tunneling operations are carried out first, and then multiple processes such as installing steel rails, spikes, and formwork positioning are carried out in the tunnel at the tail of the shield machine. Then, workers carry out cast-in-place inverted arch construction. However, this construction method has low construction efficiency and a long construction period. Summary of the Invention

The second end of the conveying pipeline is in transmission connection with the transmission mechanism. The transmission mechanism is used to drive the second end of the conveying pipeline to move along the first guide rail. The conveying pipeline is used to convey concrete;

[0015] The pouring pipe is communicated with the second end of the conveying pipe. The pouring pipe is used for a construction worker to hold, so as to guide the concrete in the conveying pipeline to the inverted arch area that needs to be poured.

[0016] As an alternative embodiment, the transmission mechanism includes a driving motor, a transmission chain, a driving wheel, a driven wheel, a driving trolley, and a plurality of driven trolleys. The driving motor and the driving wheel are disposed at the first end of the first guide rail. The driven wheel is disposed at the second end of the first guide rail. The transmission chain is wound around the driving wheel and the driven wheel. The driving motor is used to drive the driving wheel to rotate, so as to drive the transmission chain to rotate;

[0017] The first end of the conveying pipeline is fixedly connected to the first end of the first guide rail. In the direction from the first end of the first guide rail to the second end of the first guide rail, the driven trolleys and the driving trolley are sequentially slidably disposed on the first guide rail. The conveying pipeline is connected to the bottoms of the driven trolleys and the driving trolley, and the driving trolley is connected to the transmission chain. The transmission chain is used to drive the driving trolley to slide along the first guide rail, so as to drive the conveying pipeline to fold or extend.

[0018] As an alternative embodiment, the conveying pipeline is in a spiral shape and extends along the length direction of the first guide rail.

[0019] As an alternative embodiment, the paver includes a mounting frame, a vibrating mechanism, a scraper vibrating mechanism, and a roller mechanism.

[0021] As an alternative embodiment, the paver further includes a lifting mechanism. The lifting mechanism is movably disposed on the first track. The mounting frame is connected to the lifting mechanism to drive the mounting frame to lift through the lifting mechanism.

[0022] In a second aspect, the present invention further provides a shield machine, including the cast-in-place invert construction system of the first aspect, and the cast-in-place invert construction system is arranged at the lower end of the trailer of the shield machine.

[0023] The cast-in-place invert construction system provided by the present invention for a shield machine includes a first track, a second track, a concrete pouring device, a construction platform, a paver, and a formwork transfer device. The first track is connected to the lower end of the trailer of the shield machine; the second track is arranged above the first track, and the second track includes a first guide rail and a second guide rail arranged in parallel along the radial direction of the shield machine. The concrete pouring device is movably arranged on the first guide rail and is used for transporting and pouring concrete; the construction platform is movably arranged on the first track and is used for carrying construction workers; the paver is movably arranged on the first track, and in the advancing direction of the shield machine, the paver is located behind the construction platform and is used for leveling the cast invert to form the required invert; the formwork transfer device is movably arranged on the second guide rail and is used for transferring the invert formwork.

[0024] The cast-in-place invert construction system provided by the present invention is arranged at the lower end of the trailer of the shield machine, which can avoid the mutual interference between the material transportation and the invert construction during the tunneling process, enabling the shield machine to carry out the invert construction during the tunneling operation and improving the construction efficiency. During the specific construction, the formwork transfer device can first transport the invert formwork along the second guide rail to the position where the invert formwork needs to be installed, and the construction workers are transported to the position where the invert formwork is located through the construction platform for formwork installation. Then, the concrete pouring device moves along the first guide rail to the upper part of the installed invert formwork, and the constructor stands on the construction platform to operate the concrete pouring device to pour the invert. After that, the paver is moved along the second guide rail to the poured invert to level the invert at that place. Finally, the formwork at that place is removed, and the removed formwork is transported to the next construction position for installation through the formwork transfer device. It can be seen that the moving paths of the concrete pouring device, the paver, and the formwork transfer device in the cast-in-place invert construction system provided by the present invention do not interfere with each other. Therefore, the concrete pouring operation, the paver leveling operation, and the formwork transfer operation can be carried out synchronously. For example, when the concrete pouring operation is carried out, the paver can first level the already poured invert, and the formwork transfer device can also transport other invert formworks to the next construction position for installation, greatly improving the construction efficiency. At the same time, replacing manual construction with automated construction and eliminating the need for procedures such as installing steel rails and spikes in the tunnel further improves the construction efficiency. In addition, different from the existing cast-in-place invert construction that needs to be carried out at the tail of the shield machine, the cast-in-place invert construction system provided by the present invention is arranged inside the shield machine, avoiding the impact of potentially unsafe gases generated at the tail of the shield machine on the physical health of construction workers.

[0048] At present, during the construction of a shield machine tunnel, in order to avoid interference between the material transportation and the inverted arch construction during the tunneling process, generally, the tunneling operation is carried out first, and then the cast-in-place inverted arch construction is carried out. However, this construction method will reduce the construction efficiency and prolong the construction period.

[0049] In view of this, the present invention provides a cast-in-place inverted arch construction system for a shield machine, which includes a first track, a second track, a concrete pouring device, a construction platform, a paver, and a formwork transfer device. The first track is connected to the lower end of the shield machine trailer; the second track is arranged above the first track. The second track includes a first guide rail and a second guide rail that are arranged in parallel along the radial direction of the shield machine. The concrete pouring device is movably arranged on the first guide rail; the construction platform is movably arranged on the first track; the paver is movably arranged on the first track, and the paver is located behind the construction platform; the formwork transfer device is movably arranged on the second guide rail. By being arranged at the lower end of the shield machine trailer, this cast-in-place inverted arch construction system can avoid the mutual interference between the material transportation during tunneling and the inverted arch construction, enabling the shield machine to carry out inverted arch construction during tunneling operations, thereby improving the construction efficiency. Moreover, the concrete pouring operation, the leveling operation of the paver, and the formwork transfer operation can be carried out simultaneously. For example, when the concrete pouring operation is being carried out, the paver can first level the already poured inverted arch, and the formwork transfer device can also transfer other inverted arch formworks to the next construction position for installation, greatly improving the construction efficiency.

[0051] It can be referred to Figures 1 to 5, an embodiment of the present invention provides a cast-in-place inverted arch construction system 100 for a shield machine, which includes a first track 110, a second track 120, a concrete pouring device 130, a construction platform 140, a paver 150, and a formwork transfer device 160. The first track 110 is connected to the lower end of the shield machine trailer 200. The second track 120 is arranged above the first track 110. The second track 120 includes a first guide rail 121 and a second guide rail 122 arranged in parallel along the radial direction of the shield machine. The concrete pouring device 130 is movably arranged on the first guide rail 121, and the concrete pouring device 130 is used for transporting and pouring concrete. The construction platform 140 is movably arranged on the first track 110, and the construction platform 140 is used for carrying construction workers. The paver 150 is movably arranged on the first track 110, and in the direction of the shield machine's travel, the paver 150 is located behind the construction platform 140. The paver 150 is used for leveling the poured inverted arch to form the required inverted arch. The formwork transfer device 160 is movably arranged on the second guide rail 122, and the formwork transfer device 160 is used for transferring the inverted arch formwork.

[0052] Among them, the pouring platform can be used as the standing position for construction workers to operate the concrete pouring device 130, and can also transport the construction workers to the corresponding construction positions for the installation and removal of the formwork.

[0053] The cast-in-place inverted arch construction system 100 provided by the embodiments of the present invention is arranged at the lower end of the shield machine trailer 200, which can avoid the mutual interference between the material transportation and the inverted arch construction during the tunneling process, enabling the shield machine to carry out the inverted arch construction during the tunneling operation and improving the construction efficiency. During the specific construction, the formwork transfer device 160 can first transport the inverted arch formwork along the second guide rail 122 to the position where the inverted arch formwork needs to be installed, and the construction personnel are transported to the position where the inverted arch formwork is located through the construction platform 140 for formwork installation. Then, the concrete pouring device 130 moves along the first guide rail 121 to the upper part of the installed inverted arch formwork, and the constructor stands on the construction platform 140 to operate the concrete pouring device 130 to carry out the inverted arch pouring. After that, the paver 150 is moved along the second guide rail 122 to the inverted arch where the pouring is completed to level the inverted arch at that place. Finally, the formwork at that place is removed, and the removed formwork is transported to the next construction position for installation through the formwork transfer device 160. It can be seen that the moving paths of the concrete pouring device 130, the paver 150, and the formwork transfer device 160 in the cast-in-place inverted arch construction system 100 provided by the embodiments of the present invention do not interfere with each other. Therefore, the concrete pouring operation, the leveling operation of the paver 150, and the formwork transfer operation can be carried out simultaneously. For example, when the concrete pouring operation is carried out, the paver 150 can simultaneously level the already poured inverted arch, and the formwork transfer device 160 can also simultaneously transport the inverted arch formwork to the next construction position for installation, greatly improving the construction efficiency. At the same time, the manual construction is replaced by the automated construction, and there is no need for procedures such as installing steel rails and spikes in the tunnel, further improving the construction efficiency. In addition, different from the existing cast-in-place inverted arch construction that needs to be carried out at the tail of the shield machine, the cast-in-place inverted arch construction system 100 provided by the present invention is arranged inside the shield machine, avoiding the influence of the unsafe gases that may be generated at the tail of the shield machine on the physical health of the construction personnel.

[0054] In the above embodiment, the first track 110 may include two parallel third guide rails, and the projection of the second track 120 in the vertical direction falls between the two third guide rails. With such an arrangement, the concrete pouring device 130 arranged on the first guide rail 121 and the formwork transfer device 160 arranged on the second guide rail 122 can move along the gap between the two third guide rails, which can not only avoid mutual interference between them but also save space and make the structure of the cast-in-place inverted arch construction system 100 more compact.

[0055] In the above embodiments, the second track 120 may further include a support frame 123. The support frame 123 is disposed on the first track 110, and the second track 120 is disposed on the support frame 123. The support frame 123 can ensure that there is a certain distance between the first track 110, the first guide rail 121, and the second guide rail 122 in the vertical direction, further preventing the concrete pouring device 130 disposed on the first guide rail 121 and the formwork transfer device 160 disposed on the second guide rail 122 from interfering with each other.

[0056] In the above embodiments, the length of the first guide rail 121 can be made shorter than that of the second guide rail 122. It can be understood that the concrete pouring device 130 only pours a certain construction position in the same time period, while the formwork transfer system not only needs to transfer the formwork disassembled from the first construction position, but also needs to transfer the formwork to the second construction position for installation. Therefore, the moving distance of the formwork transfer device 160 is generally longer than that of the concrete pouring device 130. Thus, by designing the length of the first guide rail 121 to be shorter than that of the second guide rail 122, both cost can be saved and more operating space can be left for other equipment.

[0057] In the above embodiments, the concrete pouring device 130 may include a transmission mechanism 131, a conveying pipeline 132, and a pouring pipe 133. The transmission mechanism 131 is disposed on the first guide rail 121. The first end of the conveying pipeline 132 is connected to the first end of the first guide rail 121, and the second end of the conveying pipeline 132 is in transmission connection with the transmission mechanism 131. The transmission mechanism 131 is used to drive the second end of the conveying pipeline 132 to move along the first guide rail 121. The conveying pipeline 132 is used to convey concrete. The pouring pipe 133 is communicated with the second end of the conveying pipe, and the pouring pipe 133 is used for construction workers to hold, so as to guide the concrete in the conveying pipeline 132 to the invert area that needs to be poured.

[0058] In the above embodiments, the transmission mechanism 131 may include a driving motor 1311, a transmission chain 1312, a driving wheel 1313, a driven wheel 1314, a driving pulley 1315, and a plurality of driven pulleys 1316. The driving motor 1311 and the driving wheel 1313 are disposed at the first end of the first guide rail 121, the driven wheel 1314 is disposed at the second end of the first guide rail 121, the transmission chain 1312 is wound around the driving wheel 1313 and the driven wheel 1314, and the driving motor 1311 is configured to drive the driving wheel 1313 to rotate, thereby driving the transmission chain 1312 to rotate. The first end of the conveying pipeline 132 is fixedly connected to the first end of the first guide rail 121. In the direction from the first end of the first guide rail 121 to the second end of the first guide rail 121, the driven pulleys 1316 and the driving pulley 1315 are sequentially slidably disposed on the first guide rail 121. The conveying pipeline 132 is connected to the bottoms of the driven pulleys 1316 and the driving pulley 1315, and the driving pulley 1315 is connected to the transmission chain 1312. The transmission chain 1312 is configured to drive the driving pulley 1315 to slide along the first guide rail 121, thereby driving the conveying pipeline 132 to fold or extend. Specifically, when the driving pulley 1315 slides along the first guide rail 121 toward the first end of the first guide rail 121 driven by the transmission chain 1312, the driving pulley 1315 will push against each driven pulley 1316 to slide toward the first end of the first guide rail 121 together, thereby driving the conveying pipeline 132 to fold. Conversely, it drives the conveying pipeline 132 to extend. By folding and extending the pipeline, a certain area below can be covered, facilitating concrete pouring at different positions. Moreover, by designing the pipeline into a foldable structure, space can be saved. For example, it can be folded up when not in use without occupying too much space. In addition, such a foldable pipeline is also convenient for maintenance and replacement.

[0059] In the above embodiments, the conveying pipeline 132 may be in a spiral shape and extend along the length direction of the first guide rail 121. Designing the conveying pipeline 132 into a spiral shape can make the folding and extending process of the pipeline more orderly and avoid chaos. In addition, this design can also make the transition at the bending part of the pipeline smoother, make the concrete flow in the pipeline more smoothly, and is not easily blocked.

[0060] In the above embodiments, the paver 150 further includes a mounting frame 151, a vibrating mechanism 152, a scraper vibrating mechanism 153, and a roller mechanism 154. The mounting frame 151 is movably arranged on the first track 110, and the vibrating mechanism 152, the scraper vibrating mechanism 153, and the roller mechanism 154 are all arranged on the mounting frame 151. The vibrating mechanism 152 is used to vibrate and exhaust the inverted arch after pouring concrete. The scraper vibrating mechanism 153 is used to push away the excess concrete on the surface of the inverted arch. The roller mechanism 154 is used to compact and polish the surface of the inverted arch. Specifically, the vibrating mechanism 152 may include a plurality of high-frequency vibrating rods, and these high-frequency vibrating rods can be inserted into the poured concrete. By vibrating, the gas and moisture in the concrete are discharged, making the concrete more uniform and dense. Then, the concrete on the surface of the inverted arch can be leveled by the scraper vibrating mechanism 153, and the concrete can be made more dense and uniform through vibration, ensuring the flatness of the concrete surface, reducing the voids and unevenness inside the concrete, and further improving the quality of the concrete. Finally, the surface of the concrete can be compacted and polished by the roller mechanism 154, making the surface of the concrete smoother and further improving the flatness and quality of the concrete.

[0061] In the above embodiments, the paver 150 further includes a lifting mechanism 155. The lifting mechanism 155 is movably arranged on the first track 110, and the mounting frame 151 is connected to the lifting mechanism 155 to drive the mounting frame 151 to lift through the lifting mechanism 155, so that the paver 150 can adapt to the construction requirements of inverted arches with different cross-sections.

[0062] In addition, the present invention further provides a shield machine, which includes the cast-in-place inverted arch construction system 100 in the above embodiments. The cast-in-place inverted arch construction system 100 is arranged at the lower end of the trailer of the shield machine. The cast-in-place inverted arch construction system 100 includes a first track 110, a second track 120, a concrete pouring device 130, a construction platform 140, a paver 150, and a formwork transfer device 160. The first track 110 is connected to the lower end of the shield machine trailer 200; the second track 120 is arranged above the first track 110. The second track 120 includes a first guide rail 121 and a second guide rail 122 arranged in parallel along the radial direction of the shield machine. The concrete pouring device 130 is movably arranged on the first guide rail 121; the construction platform 140 is movably arranged on the first track 110; the paver 150 is movably arranged on the first track 110, and the paver 150 is located behind the construction platform 140; the formwork transfer device 160 is movably arranged on the second guide rail 122. By arranging the cast-in-place inverted arch construction system 100 at the lower end of the shield machine trailer 200, it is possible to avoid the mutual interference between the material transportation during tunneling and the inverted arch construction, so that the shield machine can carry out the inverted arch construction during tunneling operations, improving the construction efficiency. Moreover, the moving paths of the concrete pouring device 130, the paver 150, and the formwork transfer device 160 do not interfere with each other. Therefore, the concrete pouring operation, the leveling operation of the paver 150, and the formwork transfer operation can be carried out synchronously, greatly improving the construction efficiency of the shield machine.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
