Description

Technical Field

[0001] The present invention relates to the technical field of tunnel construction, and more specifically, to a construction method for a vibrating system of a tunnel lining trolley and a tunnel lining trolley using the construction method. Background Art

[0002] With the rapid development of railway and highway construction in China, the number of tunnel engineering constructions is increasing. Therefore, the requirements for the lining quality and standardized construction of tunnels are continuously improving.

[0003] In the traditional tunnel lining process, before pouring the secondary lining concrete, the tunnel lining trolley is first moved to the designated position, and the steel formwork of the tunnel lining trolley is overlapped with the upper slab concrete; then the secondary lining concrete is poured. During pouring, the concrete is pumped to the feeding port of the tunnel lining trolley by a ground pump, and a handheld vibrating rod is used for vibrating at each feeding port. When pouring to the arch top, an electric attached vibrating device is used for vibrating; however, due to the dense steel bars at the arch top of the secondary lining, it is impossible to perform manual vibration on the arch top concrete, and the electric vibrating device has disadvantages such as insufficient frequency and small vibration radius, resulting in difficulty in making the arch top concrete dense and full. Therefore, quality problems such as cavities, insufficient concrete strength, and uneven concrete strength appear in the tunnel lining arch top concrete, and these quality problems will bring great safety risks to the later operation of the tunnel. Therefore, the traditional tunnel lining process can no longer meet the construction requirements.

[0004] In view of the above problems, an existing vibrating system for a tunnel lining trolley, as Figure 1 shown, includes a steel formwork 11, a plurality of automatic insertion vibrating devices 12 and a plurality of pneumatic vibrating devices 13. The vibrating system of the tunnel lining trolley inserts a high-frequency vibrating rod into the arch top concrete through the automatic insertion vibrating device 12 to perform automatic insertion vibration on the arch top concrete, thereby solving the problems of arch top secondary lining voiding and non-dense concrete; in addition, the pneumatic vibrating device 13 has advantages such as high vibration frequency and large vibration radius, enabling it to vibrate deep concrete and avoiding incomplete vibration and non-dense concrete of deep concrete. However, the relative position distribution among the automatic insertion vibrating device 12, the pneumatic vibrating device 13 and the side wall feeding port 111 of the vibrating system of the tunnel lining trolley is unreasonable, the arrangement of the vibrating device at the end 112 of the steel formwork 11 is also unreasonable, and there are disadvantages in the construction method, resulting in poor vibration effect of the vibrating system of the tunnel lining trolley on the concrete, especially the vibration effect on the concrete at the longitudinal construction joint (i.e., the construction joint between the inverted arch and the secondary lining) and the circumferential construction joint (i.e., the construction joint between adjacent two slabs of the secondary lining) is poor, making it easy for the concrete at the longitudinal construction joint and / or the circumferential construction joint to have diseases, affecting the safety of the later operation of the tunnel. Summary of the Invention

[0005] In order to solve the above problems, the main object of the present invention is to provide a construction method for a vibration system of a tunnel lining trolley, which can improve the overall pouring quality of the secondary lining concrete, prevent the concrete at the vault from being hollowed out, ensure that the internal and external concrete strengths are basically the same, and the strength discrete value is small.

[0006] Another object of the present invention is to provide a tunnel lining trolley using the construction method of the above-mentioned vibration system of the tunnel lining trolley.

[0007] To achieve the main object of the present invention, the present invention provides a construction method for a vibration system of a tunnel lining trolley. The vibration system of the tunnel lining trolley includes a steel formwork. The steel formwork has two symmetrically arranged construction areas. Each construction area is provided with three layers of pouring windows, three groups of first vibration groups, two groups of second vibration groups, a third vibration group, a fourth vibration group, a fifth vibration group and a sixth vibration group. The three layers of pouring windows are distributed circumferentially along the steel formwork. The construction area has a side arch part, a first end part and a second end part. Along the first direction, the side arch part is located between the first end part and the second end part. The first vibration group and the second vibration group are both arranged on the side arch part. The three groups of first vibration groups are arranged alternately with the three layers of pouring windows in the circumferential direction. The first vibration group includes a plurality of first pneumatic vibrators distributed along the first direction. The two groups of second vibration groups are distributed in the circumferential direction. The second vibration group includes a plurality of second pneumatic vibrators distributed along the first direction. The first direction is parallel to the axis of the steel formwork. The third vibration group and the fifth vibration group are both arranged on the first end part. The third vibration group includes a plurality of third pneumatic vibrators distributed in the circumferential direction. The fifth vibration group includes at least one first inserted vibrator. The fourth vibration group and the sixth vibration group are both arranged on the second end part. The fourth vibration group includes a plurality of fourth pneumatic vibrators distributed in the circumferential direction. The sixth vibration group includes at least one second inserted vibrator. In the height direction of the steel formwork, the height of the lowermost group of first vibration groups is less than the height of the lowermost pouring window. The second vibration group is located above the uppermost pouring window. The fifth vibration group is located above the third vibration group. The sixth vibration group is located above the fourth vibration group. In the circumferential direction, adjacent two first pneumatic vibrators are arranged staggeredly. Adjacent two second pneumatic vibrators are arranged staggeredly. An adjacent first pneumatic vibrator and an adjacent second pneumatic vibrator are arranged staggeredly. The crown of the steel formwork is provided with a plurality of third inserted vibrators distributed along the first direction and a plurality of perfusion holes distributed along the first direction. Wherein, the construction method includes: pouring concrete into the lowermost pouring window of the construction area. During the pouring process, a worker operates a hand-held inserted vibrator to vibrate the concrete poured at the lowermost pouring window. When the concrete overflows the third pneumatic vibrators in the first area corresponding to the lowermost pouring window, start the third pneumatic vibrators in the first area to vibrate for a first preset duration. When the concrete overflows the fourth pneumatic vibrators in the first area, start the fourth pneumatic vibrators in the first area to vibrate for a first preset duration. When the pouring of the lowermost pouring window is completed, close the lowermost pouring window and start the lowermost group of first vibration groups to vibrate for a second preset duration;Pour concrete into the second - layer casting window in the construction area. During the pouring process, workers operate handheld plug - in vibrators to vibrate the concrete poured at the second - layer casting window. When the concrete floods over the third pneumatic vibrator in the second area corresponding to the second - layer casting window, start the third pneumatic vibrator in the second area for the third preset duration of vibration. When the concrete floods over the fourth pneumatic vibrator in the second area, start the fourth pneumatic vibrator in the second area for the third preset duration of vibration. After the pouring of the second - layer casting window is completed, close the second - layer casting window and let the second group of the first vibrator group vibrate for the fourth preset duration, and start the bottom - most group of the first vibrator group to vibrate for the fifth preset duration; Pour concrete into the top - most casting window in the construction area. During the pouring process, workers operate handheld plug - in vibrators to vibrate the concrete poured at the top - most casting window. When the concrete floods over the third pneumatic vibrator in the third area corresponding to the top - most casting window, start the third pneumatic vibrator in the third area for the sixth preset duration of vibration. When the concrete floods over the fourth pneumatic vibrator in the third area, start the fourth pneumatic vibrator in the third area for the sixth preset duration of vibration. After the pouring of the top - most casting window is completed, close the top - most casting window and start the top - most group of the first vibrator group to vibrate for the seventh preset duration, and start the second group of the first vibrator group to vibrate for the eighth preset duration; Pour concrete into the pouring hole. During the pouring process, start the third plug - in vibrator to vibrate in the first preset mode according to the requirements. When the concrete floods over the first preset distance of the first group of the second vibrator group, start the first group of the second vibrator group to vibrate for the ninth preset duration. When the concrete floods over the second preset distance of the second group of the second vibrator group, start the second group of the second vibrator group to vibrate for the tenth preset duration and start the first group of the second vibrator group to vibrate for the eleventh preset duration. When the first plug - in vibrator and the second plug - in vibrator are flooded by the concrete, start and vibrate in the second preset mode.;

[0008] As can be seen from the above, through the design of the construction method of the vibration system of the tunnel lining trolley, it is possible to better improve the vibration effect of the concrete in the side wall, arch area, crown area, and both - end areas of the steel formwork, so as to improve the compactness of the concrete, prevent the occurrence of voids in the concrete, and reduce the concrete diseases of the longitudinal construction joints and circumferential construction joints.

[0009] A preferred solution is that in the height direction, when the concrete floods over the top - most casting window by 1 meter to 1.5 meters, start the top - most group of the first vibrator group to vibrate for the twelfth preset duration.

[0010] As can be seen from the above, the above design can further improve the vibration effect of the concrete at the arch part, improve the compactness of the concrete and prevent the occurrence of voids in the concrete, and ensure the uniform strength of the concrete.

[0011] A further solution is that when the concrete pouring is completed, the second vibration group of the second set is started for vibrating for the thirteenth duration.

[0012] As can be seen from the above, the above design can further improve the vibration effect of the concrete at the arch part and the arch top, improve the compactness of the concrete and prevent the arch top from being hollow, and ensure the uniform strength of the concrete.

[0013] Another preferred solution is that after the pouring of the bottommost casting window is completed and before the bottommost casting window is closed, the worker operates a hand-held inserted vibrator to vibrate the concrete around the embedded waterstop at the first end and the second end, so that the embedded waterstop is in a straight state.

[0014] As can be seen from the above, the above operation can avoid the embedded waterstop from being squeezed and deformed and / or toppled, so that the waterstop remains in a straight state, thereby ensuring the waterproof effect of the embedded waterstop.

[0015] Another preferred solution is that the first preset vibration mode includes: controlling the third inserted vibrator to start intermittently two to four times, and vibrating for the fourteenth preset duration for each single start; the second preset vibration mode includes: controlling the first inserted vibrator to start intermittently two to four times, and vibrating for the fifteenth preset duration for each single start; controlling the second inserted vibrator to start intermittently two to four times, and vibrating for the fifteenth preset duration for each single start.

[0016] As can be seen from the above, the above design enables the concrete at the arch top and the arch part to be vibrated sufficiently, making the concrete compact and with uniform strength, and avoiding problems such as honeycombing and pitting on the concrete surface and arch top hollowness.

[0017] Another preferred solution is that the first preset distance is between 0.5 m and 0.6 m; the second preset distance is between 0.5 m and 0.6 m; in the height direction, the minimum distance between the third pneumatic vibrator and the low side wall is between 0.8 m and 1 m, the minimum distance between the fourth pneumatic vibrator and the low side wall is between 0.8 m and 1 m, and the minimum distance between the first pneumatic vibrator and the low side wall is between 0.8 m and 1 m.

[0018] As can be seen from the above, the above design enables the first pneumatic vibrator, the third pneumatic vibrator, and the fourth pneumatic vibrator to cooperate with each other to vibrate the concrete at the construction joint between the inverted arch and the secondary lining sufficiently, effectively and comprehensively, thereby ensuring the compactness of the concrete in the side wall and the end side wall area of the steel formwork and improving the pouring quality of the concrete.

[0019] A further solution is that after completing the casting and vibration of the bottom-layer cast windows of the first construction area, the casting and vibration of the bottom-layer cast windows of the second construction area are carried out; after completing the casting and vibration of the bottom-layer cast windows of the second construction area, the casting and vibration of the second-layer cast windows of the first construction area are carried out; after completing the casting and vibration of the second-layer cast windows of the first construction area, the casting and vibration of the second-layer cast windows of the second construction area are carried out; after completing the casting and vibration of the second-layer cast windows of the second construction area, the casting and vibration of the top-layer cast windows of the first construction area are carried out; after completing the casting and vibration of the top-layer cast windows of the first construction area, the casting and vibration of the top-layer cast windows of the second construction area are carried out; after completing the casting and vibration of the top-layer cast windows of the second construction area, concrete is poured into the pouring holes.

[0020] It can be seen from the above that by designing the concrete pouring sequence, the steel formwork can be balanced in force during the concrete pouring process, thereby ensuring construction safety while ensuring the quality of concrete pouring.

[0021] Another further solution is to pour concrete from the same carload into the same construction area; when the pouring of concrete from the current carload is completed, the next carload of concrete is switched to another construction area for pouring, and this cycle is repeated until the pouring of concrete for the three-story windows in the two construction areas is completed.

[0022] From the above, it can be seen that pouring concrete on the same side of the steel formwork in a single pouring process can better ensure the uniformity of the concrete on the same side of the steel formwork, and minimize the impact of subtle differences between concrete in different pouring processes on the density, strength and degree of integration of the secondary lining concrete, thereby improving the quality of concrete pouring.

[0023] A further solution is that each layer of casting windows includes multiple feeding ports distributed along a first direction, and when pouring concrete for each layer of casting windows, concrete of a preset height is poured sequentially into the multiple feeding ports in the first direction; when the tunnel lining trolley vibration system is on a slope, when pouring concrete for each layer of casting windows, concrete is poured sequentially from the feeding port with a lower height to the feeding port with a higher height.

[0024] It can be seen from the above that the above design can make the distribution of concrete more uniform, so as to avoid the problem of voids in concrete.

[0025] In order to achieve another object of the present invention, the present invention provides a tunnel lining trolley, which uses the construction method of the tunnel lining trolley vibration system mentioned above.

[0026] As can be seen from the above, the tunnel lining trolley adopting the construction method of the above-mentioned tunnel lining trolley vibration system can improve the overall pouring quality of the secondary lining concrete, ensure the compactness of the concrete and the uniformity of the concrete strength, and prevent the concrete at the crown from being void; in addition, it can also ensure that the internal and external concrete strengths are basically the same, and the strength discrete value is small.

[0061] Next, concrete is poured into the bottom pouring window 21 of the construction area 20. During the pouring process, the worker operates a hand-held insertion vibrator to vibrate the concrete poured at the bottom pouring window 21.

[0064] Preferably, after the casting of the bottom - most casting window 21 is completed and before the bottom - most casting window 21 is closed, the worker operates a hand - held immersion vibrator to vibrate the concrete around the embedded waterstop at the first end 203 and the second end 204 of the construction area 20, so that the embedded waterstop is in a straight state; this operation can prevent the embedded waterstop from being squeezed and deformed and / or toppled, so as to keep the waterstop in a straight state, thereby ensuring the waterproof effect of the embedded waterstop.

[0065] Next, pour concrete into the second - layer casting window 21 of the construction area 20.

The state of the concrete after vibration should be that the concrete is vibrated densely and the surface paste appears. During the vibration process, it is inserted slowly and pulled out slowly to fully discharge the air bubbles in the concrete.

[0066] When the concrete floods the third pneumatic vibrator 241 in the second area corresponding to the second - layer casting window 21, the control device controls the air compressor and the corresponding valve in the valve unit to start, so that the third pneumatic vibrator 241 performs vibration operation for a third preset duration; similarly, when the concrete floods the fourth pneumatic vibrator 251 in the second area corresponding to the second - layer casting window 21, the control device controls the air compressor and the corresponding valve in the valve unit to start, so that the fourth pneumatic vibrator 251 performs vibration operation for a third preset duration. Among them, the third preset duration is preferably between 30 seconds and 50 seconds.

[0067] After the casting of the second - layer casting window 21 is completed, first take out the hand - held immersion vibrator from the feeding port 211, then close each feeding port 211 of the second - layer casting window 21, and then the control device controls the air compressor and the corresponding valve in the valve unit to start, so that the second group of the first vibration groups 22, the third pneumatic vibrator 241 and the fourth pneumatic vibrator 251 in the second area perform vibration for a fourth preset duration; and make the first vibration group 22 at the bottom - most layer perform vibration for a fifth preset duration.

When the worker operates the handheld insertion vibrator for vibration, it is carried out in multiple times and multiple areas, that is, the handheld insertion vibrator vibrates the concrete poured near each feeding port 211 of the topmost casting window 21. The single vibration time is preferably between 15 seconds and 25 seconds. The state of the concrete after vibration should be that the concrete is vibrated densely and the surface slurry appears. During the vibration process, insert slowly and pull out slowly to fully discharge the air bubbles in the concrete.

[0069] When the concrete overflows the third pneumatic vibrator 241 in the third area corresponding to the topmost casting window 21, the control device controls the corresponding valves in the air compressor and the valve unit to start, so that the third pneumatic vibrator 241 performs a sixth preset duration of vibration operation; similarly, when the concrete overflows the fourth pneumatic vibrator 251 in the second area corresponding to the topmost casting window 21, the control device controls the corresponding valves in the air compressor and the valve unit to start, so that the fourth pneumatic vibrator 251 performs a sixth preset duration of vibration operation. Among them, the sixth preset duration is preferably between 30 seconds and 50 seconds.

[0070] After the pouring of the topmost casting window 21 is completed, first take out the handheld insertion vibrator from the feeding port 211, then close each feeding port 211 of the topmost casting window 21, and then the control device controls the corresponding valves in the air compressor and the valve unit to start so that the uppermost group of first vibrator groups 22, the third pneumatic vibrator 241 in the third area, and the fourth pneumatic vibrator 251 perform a seventh preset duration of vibration; and make the second group of first vibrator groups 22 perform an eighth preset duration of vibration. Among them, the seventh preset duration is preferably between 30 seconds and 50 seconds; the fifth preset duration is preferably between 40 seconds and 60 seconds.

[0071] Next, pour concrete into the perfusion hole 29. During the pouring process, start the third insertion vibrator 28 to perform the first preset mode of vibration according to requirements. Specifically, when the concrete overflows the third insertion vibrator 28 located at the crown, the control device controls the corresponding valves in the air compressor and the valve unit to start so that the third insertion vibrator 28 performs the first preset mode of vibration. The first preset vibration mode is: control the third insertion vibrator 28 to start intermittently two to four times, and each single start performs a thirteenth preset duration of vibration. Among them, the fourteenth preset duration is preferably between 20 seconds and 35 seconds.

[0072] When the concrete overflows the first preset distance of the first group of second vibrator groups 23, start the first group of second vibrator groups 23 to perform a ninth preset duration of vibration. Among them, the first preset distance is preferably between 0.5 meters and 0.6 meters, and the ninth preset duration is preferably between 25 seconds and 40 seconds.

[0073] When the concrete floods over the second preset distance of the second vibration group 23 of the second group, start the second vibration group 23 of the second group for vibration for the tenth preset duration and start the second vibration group 23 of the first group for vibration for the eleventh preset duration.

When the concrete pouring is completed, start the second vibration group 23 of the second group for vibration for the thirteenth duration, and the thirteenth preset duration is preferably between 30 seconds and 50 seconds.

[0076] It should be noted that the above construction process is an example of the concrete pouring construction sequence for a single construction area 20 to facilitate the understanding of the concrete pouring process in the construction area 20 by those skilled in the art. In the actual concrete pouring construction process, the two construction areas 20 need to be symmetrically poured. The specific timing for switching the concrete pouring between the two construction areas 20 preferably includes the following two types:

[0077] First, after the pouring and vibration of the bottom - most casting window 21 of the first construction area 20 are completed, the pouring and vibration of the bottom - most casting window 21 of the second construction area 20 are carried out; after the pouring and vibration of the bottom - most casting window 21 of the second construction area 20 are completed, the pouring and vibration of the second - layer casting window 21 of the first construction area 20 are carried out; after the pouring and vibration of the second - layer casting window 21 of the first construction area 20 are completed, the pouring and vibration of the second - layer casting window 21 of the second construction area 20 are carried out; after the pouring and vibration of the second - layer casting window 21 of the second construction area 20 are completed, the pouring and vibration of the top - most casting window 21 of the first construction area 20 are carried out; after the pouring and vibration of the top - most casting window 21 of the first construction area 20 are completed, the pouring and vibration of the top - most casting window 21 of the second construction area 20 are carried out; after the pouring and vibration of the top - most casting window 21 of the second construction area 20 are completed, concrete is poured into the pouring hole 29. During the process of pouring concrete into the pouring hole 29, it is preferred to first pour concrete into the first construction area 20 until it exceeds the first preset distance of the first group of the second vibrating group 23, and then switch to the second construction area 20 for concrete pouring; when the concrete in the second construction area 20 exceeds the first preset distance of the first group of the second vibrating group 23, switch to the first construction area 20 for concrete pouring; when the concrete in the first construction area 20 exceeds the second preset distance of the second group of the second vibrating group 23, switch to the second construction area 20 for concrete pouring; when the concrete in the second construction area 20 exceeds the second preset distance of the second group of the second vibrating group 23, switch to the first construction area 20 for concrete pouring. Pour in this cyclic manner. When the concrete approaches the arch - top area of the steel formwork 2, concrete can be poured into the two construction areas 20 simultaneously.

[0078] Second, the concrete of the same vehicle is poured into the same construction area 20. After the pouring of the concrete of the current vehicle is completed, the concrete of the next vehicle is switched to the other construction area 20 for pouring. This cycle continues until the concrete pouring of the three - layer casting windows 21 of the two construction areas 20 is completed. Similarly, during the process of pouring concrete into the pouring hole 29, it is preferred to first pour concrete into the first construction area 20 until it exceeds the first preset distance of the first group of the second vibrating group 23, and then switch to the second construction area 20 for concrete pouring; when the concrete in the second construction area 20 exceeds the first preset distance of the first group of the second vibrating group 23, switch to the first construction area 20 for concrete pouring; when the concrete in the first construction area 20 exceeds the second preset distance of the second group of the second vibrating group 23, switch to the second construction area 20 for concrete pouring; when the concrete in the second construction area 20 exceeds the second preset distance of the second group of the second vibrating group 23, switch to the first construction area 20 for concrete pouring. Pour in this cyclic manner. When the concrete approaches the arch - top area of the steel formwork 2, concrete can be poured into the two construction areas 20 simultaneously.

[0079] In addition, when pouring concrete into each layer of the pouring window 21, pour concrete of a preset height into a plurality of feeding ports 211 in sequence in the first direction X; when pouring concrete into a plurality of perfusion holes 29 at the vault, pour concrete of a preset height into a plurality of perfusion holes 29 in sequence in the first direction X. When the vibrating system 200 of the tunnel lining trolley is on a slope, when pouring concrete into each layer of the pouring window 21, pour concrete from the feeding port 211 with a lower height to the feeding port 211 with a higher height in sequence; when pouring concrete into a plurality of perfusion holes 29 at the vault, pour concrete from the perfusion hole 29 with a lower height to the perfusion hole 29 with a higher height in sequence.

[0080] Combined with Figure 10 , use ground penetrating radar and elastic wave method to compare the strength and density of the structural layout and use effect of the internal vibrator and the attached pneumatic vibrator of the vibrating system 200 of the tunnel lining trolley of this tunnel. Among them, there is no obvious difference in the radar waveform, and the results of the elastic wave method show that the lining concrete vibrated by the internal vibrator is denser than that vibrated by the pneumatic vibrator, especially in the area close to the waterproof board, the effect is more obvious.

[0081] During the construction process of the vibrating system 200 of the tunnel lining trolley of this tunnel, randomly select 3 consecutive slabs for detection, measure 2 points for each slab, and respectively measure the surface layer and deep layer strength analysis. Among them, the acoustic wave rebound method detection data of the lining vault strength before and after the modification of the lining trolley can be seen in Figure 11 . It can be seen that the construction concrete strength before and after the modification can meet the design requirements; but comparing the data, the surface layer and deep layer strength dispersion of the constructed lining after the modification is smaller and basically the same, while the surface layer and deep layer strength dispersion of the constructed lining before the modification is larger, which is related to the uneven distribution of aggregates caused by insufficient concrete vibration. Therefore, the strength of the deep area of the lining vault close to the waterproof board after the modification is slightly higher.

[0082] In summary, it can be seen that the vibrating system of the tunnel lining trolley and its construction method provided by the present invention can better improve the vibrating effect of the concrete in the side wall, arch area, vault area, and both end areas of the steel formwork, so as to improve the density of the concrete, prevent the concrete from having cavities, and reduce the concrete diseases of the longitudinal construction joint and the circumferential construction, thereby effectively improving the overall pouring quality of the secondary lining concrete, preventing the concrete at the vault from being hollow, ensuring that the concrete strength is basically the same inside and outside, and the strength dispersion value is small.

[0083] Embodiment of the tunnel lining trolley

[0084] The tunnel lining trolley includes the tunnel lining trolley vibration system in the embodiments of the above tunnel lining trolley vibration system, and uses the construction method of the above tunnel lining trolley vibration system to construct the secondary lining of the tunnel. It can be seen that the tunnel lining trolley adopting the tunnel lining trolley vibration system and its construction method can improve the overall pouring quality of the secondary lining concrete, ensure the compactness of the concrete and the uniformity of the concrete strength, and prevent the concrete at the arch top from being void; in addition, it can also ensure that the internal and external concrete strengths are basically the same, and the strength discrete value is small.

[0085] Finally, it should be emphasized that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
