Abstract
Description
Technical Field
[0001] The invention relates to shield tunnel construction, and in particular to a synchronous grouting device used for shield tunnel construction. Background Art
[0002] The shield method is a fully mechanized construction method in the dark excavation method. It uses a shield machine to advance in the stratum, and supports the surrounding rock through the shield shell and segments to prevent collapse into the tunnel. At the same time, a cutting device is used to excavate the soil in front of the excavation face, and the soil is transported out of the cave by an excavation machine, and pressurized and pushed forward at the rear by jacks, and precast concrete segments are assembled to form a tunnel structure.
[0003] Synchronous grouting is one of the important links in shield construction. It refers to the process of injecting an appropriate amount of slurry material into the gap between the end of the shield shell and the segment while the shield is advancing. It is a key measure to reduce the ground disturbance and displacement caused by construction. The control of synchronous grouting speed is crucial for the safe construction of shields, especially when the shield is passing through existing buildings (structures) with a small spacing. The mismatch between the shield excavation speed and the synchronous grouting speed can easily cause excessive deformation of existing buildings (structures), or even collapse and damage.
[0004] The existing synchronous grouting devices have the following problems: (1) The grouting material is a high-solid particle slurry. As a contact metering method, the flow meter not only has limited metering accuracy, but is also very easy to damage. The shield machine has a complex structure and a small internal space, and it is difficult to replace parts after damage. (2) The existing synchronous grouting devices mostly count the number of strokes of the grouting pump and multiply the number of strokes by the theoretical volume of a single stroke to calculate the volume. Since there is a large error between the theoretical volume of a single stroke and the actual volume of a single stroke, the final measurement result is far from the actual situation. On the other hand, it is impossible to monitor the grouting speed. Summary of the invention
[0005] Purpose of the invention: The purpose of the present invention is to provide a synchronous grouting device for shield tunnel construction that can reliably monitor the grouting speed.
[0006] Technical solution: The synchronous grouting device for shield tunnel construction described in the present invention includes a slurry storage box, the inner wall of the slurry storage box forms a slurry storage tank, and a partition structure is arranged in the slurry storage tank for dividing the slurry storage tank into multiple partitions; each partition is equipped with a stirring mechanism, a grouting mechanism and a liquid level monitoring mechanism; the stirring mechanism includes a U-shaped frame, the U-shaped frame is arranged in the partition and the bottom of the U-shaped frame is in contact with the bottom of the slurry storage tank, and the inner wall of the U-shaped frame is provided with a scale label; the liquid level monitoring mechanism includes a camera, the camera is installed on the U-shaped frame and is located above the highest liquid level, and the scale label is within the collection range of the camera; the grouting speed is determined according to the partition liquid level collected in real time by the camera and the mortar volume corresponding to the different liquid levels calibrated in advance.
[0007] Furthermore, the grouting material is generally a cementitious material, and pipe blockage is prone to occur during the grouting process, delaying the progress of shield construction. The shield driver needs to grasp the physical state of the grouting material in real time. However, the current state of the grouting material is mainly determined by human judgment, which is highly subjective and difficult to monitor, and there are also great limitations in accuracy. To this end, the stirring mechanism also includes a motor and a torque sensor. The motor is installed on the top of the U-shaped frame, and its output shaft passes through the U-shaped frame downward. The torque sensor is installed on the U-shaped frame. One end of the measuring shaft of the torque sensor is installed on the output end of the motor, and the other end of the measuring shaft is installed with a stirring shaft, and a spiral stirring blade is installed on the stirring shaft; before the shield tunneling, it is necessary to combine indoor tests to determine the mapping relationship between the mortar consistency and the stirring torque. When the motor is turned on, the spiral stirring blade can be driven to stir the mortar in the corresponding partition. At the same time, as the mortar consistency in the partition changes, the torque detected by the torque sensor can change, and the torque of the stirring shaft of each partition can be recorded when it rotates, so as to judge the physical state of the slurry, and then it is convenient to adjust the stirring speed of the spiral stirring blade or add water to dilute it according to the change of torque, so as to monitor the slurry consistency.
[0008] Furthermore, each partition is also provided with a cleaning mechanism, which includes an annular diverter pipe installed on a U-shaped frame and with multiple nozzles distributed around the annular diverter pipe. A delivery pipe is connected to the annular diverter pipe, which connects a water pipe and a water pump.
[0009] Furthermore, a filtering mechanism is installed on the grouting mechanism, and the grouting mechanism includes a grouting pump, and the suction end of the grouting pump is connected to a grouting pipe, and the grouting pipe is connected to the partition; the delivery end of the grouting pump is connected to the grouting pipe, and an electric three-way valve is installed on the grouting pipe; the filtering mechanism includes a filter box, and a filter plate is arranged in the filter box. The filter box is connected to the other outlet of the electric three-way valve through a guide pipe, and the filtered water is returned to the partition through a reflux pipe.
[0010] After the grouting work is completed, the electric three-way valve can be controlled to connect the grouting pipe with the diversion pipe, and then the delivery pipe can be connected to the water pipe and the water pump to deliver water, so that the water is sprayed on the inner wall of the slurry storage box and other locations through the nozzle for flushing. At the same time, the grouting pump can be turned on to pump out the water and make it flow to the grouting pipe, diversion pipe and filter box, and finally return to the slurry storage box through the reflux pipe. During the process, the filter plate can be used to filter out the sand and large particles in the mortar, and when the water flows through the grouting pipe, the mortar inside can be flushed out to prevent the mortar from solidifying in the grouting pipe and the grouting pipe and causing blockage.
[0011] Furthermore, there are multiple filter plates, which are spaced between two oppositely arranged support plates, and sealing covers are fixed on the top of the two support plates; the upper part of the filter box is open, and the two support plates are inserted into the filter box from top to bottom, and the sealing cover is detachably fixed to the top of the filter box.
[0012] Furthermore, the partition structure includes a first partition and a second partition, the left and right inner walls of the slurry storage tank have several pairs of first card slots, and the first partition is inserted into the paired first card slots; the front and rear inner walls of the slurry storage tank have several second card slots, and the first partition has third card slots on both sides that are paired with the second card slots on the front and rear inner walls of the slurry storage tank, and the second partition is inserted into the paired second and third card slots.
[0013] Furthermore, guide frames are installed at the front and rear sides of the slurry storage box, a connecting frame is slidably arranged on the guide frame, and a U-shaped frame is installed at one end of the connecting frame; the stirring mechanism is placed in the middle position of the partition by moving the connecting frame.
[0014] Furthermore, a guide slide groove is provided on the guide frame, a guide slider is slidably connected in the guide slide groove, and the guide slider is installed at the other end of the connecting frame.
[0015] Furthermore, rubber pads are arranged in the first, second and third card slots.
[0016] Furthermore, a flushing pipe is installed on the U-shaped frame, the water outlet of the flushing pipe is toward the lens of the camera, and the flushing pipe is connected to the water pipe and the water pump.
[0017] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: After the ground mortar is transported to the slurry storage box, the position of the mortar of each partition in the slurry storage box on the scale label is obtained through the camera to determine the volume of the remaining mortar in each partition in the slurry storage box, and then the change of the grouting amount of each partition per unit time (i.e., the slurry injection speed) is obtained. The grouting speed obtained in this way is used as a reference to adjust the stroke frequency of the grouting pump to change the grouting speed to match the excavation speed, realize the grouting control of different pipeline partitions, and ensure that the grouting material fully fills and reinforces the gaps and cracks during the excavation process. Using this level monitoring flow metering method instead of a flow meter can avoid the problem of cumbersome replacement due to damage to the flow meter, and has higher reliability.

Each partition is equipped with a stirring mechanism 5, a grouting mechanism 6, a liquid level monitoring mechanism 7 and a cleaning mechanism 8, wherein the stirring mechanism 5 is used to stir the mortar in the partition, the grouting mechanism 6 is used to extract and transport the mortar, the liquid level monitoring mechanism 7 is used to detect the liquid level in the partition so as to adjust the grouting speed, and the cleaning mechanism 8 is used to flush the partition after the grouting is completed, and the liquid level monitoring mechanism 7 and the cleaning mechanism 8 are installed on the stirring mechanism 5. In addition, a filtering mechanism 9 is installed on the grouting mechanism 6 to filter the flushing water and send it back to the corresponding partition.
[0035] The partition structure 4 includes a plurality of first card plates 401 and a plurality of second card plates 404. A first card slot 402 is formed between two adjacent first card plates 401, and a second card slot 405 is formed between two adjacent second card plates 404. The plurality of first card plates 401 are mounted on the left and right inner walls of the pulp storage tank 3, and the first partition plates 403 are inserted into the first card slots 402 corresponding to the left and right sides. A plurality of third card plates 406 are mounted on both sides of the first partition plate 403, and a third card slot 407 is formed between two adjacent third card plates 406. The plurality of second card plates 404 are mounted on the front and rear inner walls of the pulp storage tank 3, and the second partition plates 408 are inserted into the second card slots 405 and the third card slots 407 corresponding to the front and rear sides. In this embodiment, rubber pads are provided in the first card slots 402, the second card slots 405, and the third card slots 407.
[0036] When in use, first insert the two ends of the second partition 403 into the first card slots 402 opposite to each other on the left and right sides respectively, then select a second partition 408 of appropriate length according to the distance between the first partition 403 and the inner wall of the slurry storage tank 3, and insert the two ends of the second partition 408 into the second card slot 405 and the third card slot 407 opposite to each other on the front and back sides respectively, so as to divide the slurry storage tank 3 into four partitions.
[0037] The front and rear sides of the slurry storage box 2 are both equipped with guide frames 501, and a connecting frame 502 is slidably arranged on the guide frame 501. A U-shaped frame 503 is installed at one end of the connecting frame 502, and the bottom of the U-shaped frame 503 contacts the bottom of the slurry storage tank 3. The stirring mechanism 5 includes a motor 504, which is installed on the top of the U-shaped frame 503, and the output end of the motor 504 passes through the U-shaped frame 503. A torque sensor 507 is installed on the U-shaped frame 503, and a measuring shaft is provided on the torque sensor 507. One end of the measuring shaft is installed on the output end of the motor 504, and the other end of the measuring shaft is installed on the stirring shaft 505, and a spiral stirring blade 506 is installed on the stirring shaft 505.
[0038] In this embodiment, a guide slot 508 is provided on the guide frame 501, and a guide slider 509 is slidably installed in the guide slot 508. The guide slider 509 is installed at the other end of the connecting frame 502. By pushing the connecting frame 502, the guide slider 509 can be driven to slide in the guide slot 508 on the guide frame 501, thereby limiting the moving direction of the connecting frame 502. Therefore, the stirring position can be adjusted according to the size of the partitions separated in the slurry storage box 2. By pushing the connecting frame 502, the spiral stirring blade 506 can be driven to move, so that the spiral stirring blade 506 is located in the middle position of the partition.
[0039] When stirring, the motor 504 is turned on, and the output end of the motor 504 can drive the measuring shaft of the torque sensor 507 to rotate, so that the measuring shaft drives the stirring shaft 505 and the spiral stirring blade 506 to rotate, so that the mortar in the corresponding partition is stirred to prevent premature coagulation. The output shaft of the motor 504 of each partition is provided with a torque sensor 507, which can record the torque of the stirring shaft 505 of each partition when it rotates, and judge the physical state of the slurry by combining the mapping relationship between the pre-measured mortar consistency and the stirring torque.
[0040] The grouting mechanism 6 includes a grouting pump 601, which is installed on the support frame 1. The suction end of the grouting pump 601 is connected to a grouting pipe 602, which is connected to the slurry storage box 2 and communicated with the partition. The delivery end of the grouting pump 601 is connected to a grouting pipe 603, and an electric three-way valve 604 is provided on the grouting pipe 603. The grouting pump 601 is turned on to extract the slurry in the partition, and the slurry is gradually pressed into the shield tail gap through the electric three-way valve 604 and the grouting pipe 603.
[0041] Example 2
[0042] This embodiment 2 is a further improvement made on the basis of embodiment 1.
[0043] like Figures 1 to 4 As shown, in order to conveniently capture the changes in the grouting amount of each partition per unit time in the slurry storage box 2 so as to adjust the grouting speed, a liquid level monitoring mechanism 7 is installed on the stirring mechanism 5.
[0044] The liquid level monitoring mechanism 7 includes a camera 701, which is mounted on a U-shaped frame 503 and is located above the highest liquid level. The inner wall of the U-shaped frame 503 is provided with a scale label 702, which is located within the acquisition range of the camera 701. A flushing pipe 703 is installed on the U-shaped frame 503, and the water outlet of the flushing pipe 703 is directed toward the lens of the camera 701. The position of the mortar amount in the partition at the scale label 702 can be obtained through the camera 701, and water can be sprayed onto the lens of the camera 701 by connecting the flushing pipe 703 to a water pipe to clean the lens of the camera 701.
[0045] The setting of the liquid level monitoring mechanism 7 can capture the change of the grouting amount of each partition in the slurry storage box 2 per unit time, that is, the slurry injection speed, V 注浆 =(V t1 -V t2 ) / (t2-t1), where t1 and t2 are the recording times, V t1 、V t2 is the volume of slurry in the slurry storage box 2 at time t1 and t2. The grouting speed obtained in this way is used as a reference to adjust the stroke frequency of the grouting pump 601 to change the grouting speed to match the excavation speed. The grouting speed should satisfy: V 注浆 =V 掘进 ×Π(Dd) / 4, where V 掘进 is the tunneling speed of the shield machine, D is the cutterhead diameter of the shield machine, and d is the tail shield diameter of the shield machine.
[0046] Example 3
[0047] This embodiment 3 is a further improvement made on the basis of embodiment 2.
[0048] like Figures 1 to 7 As shown, in order to prevent the remaining mortar from solidifying and clogging in the grouting pipe 603 after the grouting is completed, a cleaning mechanism 8 is installed on the stirring mechanism 5 and a filtering mechanism 9 is installed on the grouting mechanism 6.
[0049] The cleaning mechanism 8 includes an annular diverter pipe 801, which is installed on the U-shaped frame 503. A plurality of nozzles 802 are installed on the annular diverter pipe 801. The plurality of nozzles 802 are distributed around the U-shaped frame 503. A delivery pipe 803 is connected to the annular diverter pipe 801. The delivery pipe 803 is connected to the annular diverter pipe 801, and the delivery pipe 803 is connected to the water pipe and the water pump.
[0050] The filter mechanism 9 includes a filter box 901, and a guide pipe 902 is connected to the filter box 901, and the other end of the guide pipe 902 is connected to the other outlet of the electric three-way valve 604. Two support plates 903 are movably installed on the inner wall of the filter box 901, and a plurality of filter plates 904 are arranged between the two support plates 903 at intervals. A sealing cover 905 is fixed on the top of the two support plates 903, and the sealing cover 905 is in contact with the top of the filter box 901. A return pipe 906 is connected to the filter box 901, and one end of the return pipe 906 is located below the plurality of filter plates 904, and the other end of the return pipe 906 is located above the slurry storage box 2. A pipe rack 907 is installed on the return pipe 906, and the pipe rack 907 is installed on one side of the guide frame 501. A threaded seat 908 is installed on the filter box 901 , a positioning block 909 is installed on the sealing cover 905 , one end of a fixing bolt 910 is movably installed on the positioning block 909 , and the other end of the fixing bolt 910 passes through the positioning block 909 and is threadedly installed in the threaded seat 908 .
[0051] After the grouting work is completed, the delivery pipe 803 can be connected to the water pipe and the water pump to pump water into the annular diverter pipe 801, and then the water can be sprayed on the inner wall of the slurry storage box 2 and the first partition plate 403 and the second partition plate 408 through the nozzle 802 for washing, and at the same time, the remaining mortar in the slurry storage box 2 can be diluted. At this time, the electric three-way valve 604 can be controlled to connect the grouting pipe 603 with the guide pipe 902, and then the grouting pump 601 is turned on to pump out the water and mortar in the slurry storage box 2, so that the water and mortar flow through the filter plate 904, thereby filtering out sand and large particles, and the remaining water returns to the slurry storage box 2 through the return pipe 906, so that the water can be recycled. When the water flows through the grouting pipe 603, the mortar inside it can be flushed out to prevent the mortar from solidifying in the grouting pipe 603 and causing blockage.
[0052] The working principle of the present invention is as follows:
[0053] Before shield tunneling, it is necessary to determine the mapping relationship between mortar consistency and stirring torque in combination with indoor tests, and calibrate the volume corresponding to different liquid levels in the partitions. When using the device, it is necessary to first adjust the first partition 403 and the second partition 408 to the appropriate position in combination with the grouting conditions of each pipeline. If there are no special circumstances, the partition is adjusted to the middle position by default, dividing the slurry storage tank 3 into four equal parts.
[0054] After the ground mortar is transported to the slurry storage box 2, each partition stirring mechanism 5 starts working. During the process, the stirring position can be adjusted to the middle position of the partition according to the size of the partition separated in the slurry storage box 2. The output end of the motor 504 can drive the measuring shaft of the torque sensor 507 to rotate, so that the measuring shaft drives the stirring shaft 505 to rotate, and the rotating stirring shaft 505 drives the spiral stirring blade 506 to stir the mortar in the corresponding partition. By stirring the mortar, premature coagulation can be avoided. At the same time, the torque sensor 507 set on the output shaft of the motor 504 at the corresponding position of each partition can record the torque of the stirring shaft 505 of each partition when it rotates, so as to judge the physical state of the slurry.
[0055] When the shield machine starts to excavate, the grouting pump 601 can be turned on to extract the slurry in the slurry storage box 2, so that the slurry is gradually pressed into the shield tail gap through the electric three-way valve 604 and the grouting pipe 603. By setting the camera 701, the position of the mortar amount in the partition at the scale label 702 can be obtained (the liquid level is obtained by the image recognition algorithm, which is the prior art), and the flushing pipe 703 can be connected to the water pipe to spray water on the lens of the camera 701, which can be used to clean the lens of the camera 701 to prevent the slurry from dirtying the lens and affecting the measurement accuracy. Then, the grouting speed of each partition is obtained by the above formula, and the obtained grouting speed is used as a reference to adjust the stroke frequency of the grouting pump 601 to change the grouting speed to match the excavation speed.
[0056] After the grouting work is completed, the delivery pipe 803 can be connected to the water pipe and the water pump to pump water into the annular diverter pipe 801, and then the water is sprayed on the inner wall of the slurry storage box 2 and the first partition plate 403 and the second partition plate 408 through the nozzle 802 for washing, and at the same time, the remaining mortar in the slurry storage box 2 is diluted. At this time, the electric three-way valve 604 can be controlled to switch the flow direction, so that the grouting pipe 603 is connected with the guide pipe 902, and then the grouting pump 601 is turned on to pump out the water and mortar in the slurry storage box 2, so that the water and mortar flow through the grouting pipe 603 and the guide pipe 902 into the filter box 901, and the water and mortar will flow through the filter plate 904, and the sand and large particles in the mortar will be blocked by the filter plate 904, and the remaining water will return to the slurry storage box 2 through the return pipe 906, so that the water can be recycled. Furthermore, when water flows through the grouting pipe 603, the mortar inside the grouting pipe 603 can be flushed out to prevent the mortar from solidifying in the grouting pipe 603 and causing blockage, so as to facilitate subsequent use.
[0057] After flushing is completed, the fixing bolt 910 at the corresponding position can be rotated and unscrewed from the threaded seat 908 and the positioning block 909. At this time, the restriction on the sealing cover 905 can be released. The sealing cover 905 can be pulled to pull the support plate 903 and the filter plate 904 out of the filter box 901 so as to clean the sand and gravel particles remaining on the filter plate 904.
