Description

Technical Field

[0001] The invention relates to the technical field of shield construction, and in particular to a tunnel slag recycling system and a processing method thereof. Background Art

[0002] The shield method is a fully mechanized construction method in the dark excavation method. It pushes the shield machine into the ground, and supports the surrounding rock with the shield shell and segments to prevent collapse into the tunnel. At the same time, the soil is excavated in front of the excavation face with a cutting device, transported out of the hole by an excavation machine, and pushed forward by a jack at the rear, and prefabricated concrete segments are assembled to form a mechanized construction method of the tunnel structure.

[0003] A large amount of slag will be generated during the shield construction process. In the prior art, the slag generated in the construction of conventional underground tunnels is first transported from the excavation surface to the working pit through a newly built pipeline, and then the slag is barged from the working pit to the ground. Part of the slag is piled in the soil collection pit in the construction site, and the other part of the slag is directly transported outside or barged inside the site and then transported outside, which cannot be recycled. The on-site loading of slag will cause damage to the pile, deformation and cracking, endangering the safety of personnel, and will also cause environmental pollution such as dust and sand. At the same time, due to the large number of times the slag is barged, turned over and transported outside, the construction cost is high.

[0004] In addition, after the tunnel construction is completed, a large amount of synchronous grouting materials need to be purchased for shield excavation and to fill the gap between the pipe segment and the shield casing to prevent the tunnel from settling and deformation. The current synchronous grouting liquid is mainly purchased from the factory as a finished commercial slurry with standard composition and performance indicators. The finished commercial slurry takes a long time to transport and is expensive, which will affect the efficiency and cost of tunnel construction. Existing studies have shown that slag has the possibility of synchronous grouting, but there is a lack of systems and treatment methods for improving slag to be suitable for synchronous grouting. Therefore, a tunnel slag recycling system and treatment method are urgently needed to solve the above technical problems. Summary of the invention

[0005] The purpose of the present invention is to provide a tunnel slag recycling system, which can realize the efficient and recycling utilization of slag in shield construction, thereby reducing environmental pollution and construction costs.

[0006] To achieve this object, the present invention adopts the following technical solutions:

[0007] A tunnel slag recycling system, comprising:

[0008] The feeding mechanism comprises a storage bin and a processing bin, wherein the inlet end of the storage bin is configured to feed the slag generated by the shield machine during construction into the storage bin, and the outlet end of the storage bin is selectively connected to the processing bin;

[0016] Optionally, the detection mechanism includes a monitoring unit and a control unit, wherein the monitoring unit is disposed in the processing chamber and is communicatively connected to the control unit, and the control unit is capable of controlling the action of the conveying mechanism.

[0017] Another object of the present invention is to provide a method for processing tunnel debris, which can achieve efficient and circular utilization of the debris in shield construction, thereby reducing environmental pollution and construction costs.

[0018] To achieve this object, the present invention adopts the following technical solutions:

[0019] A method for processing tunnel debris, using the tunnel debris recycling system as described above, the method for processing tunnel debris comprising:

[0020] Step 1: transport the slag generated by the shield machine during tunnel construction to the storage bin;

[0022] Step 3: adding filler into the processing chamber through the adding mechanism to form a slurry;

[0023] Step 4: stirring the slurry in the processing bin by a stirring mechanism;

[0024] Step 5: Detect whether the performance value of the slurry in the processing bin meets the design indicators through the detection mechanism. If the performance value of the slurry meets the design indicators, the slurry with the performance value meeting the design indicators is transported to the grouting end of the shield machine through the conveying mechanism; if the performance value of the slurry does not meet the design indicators, filler is added to the processing bin again through the adding mechanism until the performance value of the slurry meets the design indicators, and the slurry with the performance value meeting the design indicators is transported to the grouting end of the shield machine through the conveying mechanism.

[0025] Optionally, in step one, the slag excavated by the shield machine is transported to a storage bin by a screw conveyor.

[0030] The present invention provides a tunnel slag recycling system, which includes a feeding mechanism, a feeding mechanism, a stirring mechanism, a detection mechanism and a conveying mechanism. The feeding mechanism includes a storage bin and a processing bin. The storage bin collects the slag generated by the shield machine during construction, which is convenient for unified storage and management, avoids the random stacking of slag at the construction site, and thus reduces the potential safety hazards such as stacking damage, deformation and cracking.

Through the above-mentioned settings, the tunnel slag recycling system of the present application can achieve efficient and cyclic utilization of slag in shield construction, reducing environmental pollution and construction costs.

[0031] The present invention also provides a method for processing tunnel slag, which adopts a tunnel slag recycling system. First, the slag generated by the shield machine during tunnel construction is transported to a storage bin to realize centralized storage of the slag for subsequent processing. Then, the slag in the storage bin is transported to a processing bin to provide raw materials for the preparation of slurry. Fillers are added to the processing bin through a feeding mechanism to form slurry to improve the performance of the slag so that it meets the grouting requirements. Then, the slurry in the processing bin is stirred by a stirring mechanism to ensure that the components are evenly mixed to improve the uniformity and stability of the slurry and ensure the grouting effect. Finally, a detection mechanism is used to detect whether the performance value of the slurry in the processing bin meets the design indicators. If the performance value of the slurry meets the design indicators, the slurry with the performance value meeting the design indicators is transported to the grouting end of the shield machine through the conveying mechanism. If the performance value of the slurry does not meet the design index, fillers are added to the processing bin again through the feeding mechanism until the performance value of the slurry meets the design index, and the slurry with performance values ​​that meet the design index is transported to the grouting end of the shield machine through the conveying mechanism to ensure that the performance of the grouting slurry meets the design requirements and improve the efficiency and safety of shield construction. Through the above settings, the tunnel slag processing method of the present application can achieve efficient and recycled utilization of slag in shield construction, reducing environmental pollution and construction costs.

[0040] like Figure 1 As shown, this embodiment provides a tunnel slag recycling system, which includes a feeding mechanism 1, a feeding mechanism 2, a stirring mechanism 3, a detection mechanism 4 and a conveying mechanism 5. The feeding mechanism 1 includes a storage bin 11 and a processing bin 12. The inlet end of the storage bin 11 is configured to pass the slag generated by the shield machine 100 during construction into the storage bin 11. The outlet end of the storage bin 11 is selectively connected to the processing bin 12. The feeding mechanism 2 is selectively connected to the processing bin 12 and is configured to add fillers to the processing bin 12 to form slurry. The stirring output end of the stirring mechanism 3 is arranged in the processing bin 12. The detection mechanism 4 is configured to detect whether the performance value of the slurry in the processing bin 12 meets the design index. The conveying mechanism 5 can convey the slurry in the processing bin 12 to the grouting end of the shield machine 100.

[0041] In this embodiment, the feeding mechanism 1 includes a storage bin 11 and a processing bin 12. The storage bin 11 is used to centrally collect the slag generated by the shield machine 100 during construction, which is convenient for unified storage and management, avoiding the random loading of slag at the construction site, thereby reducing the potential safety hazards such as loading damage, deformation and cracking. The outlet end of the storage bin 11 is selectively connected to the processing bin 12, and the time and amount of slag entering the processing bin 12 can be flexibly controlled according to the construction requirements, so as to facilitate the improvement of the slag. The feeding mechanism 2 is selectively connected to the processing bin 12, and fillers can be added to the processing bin 12 to form slurry, thereby improving the slag and making it have the performance suitable for synchronous grouting. The stirring output end of the stirring mechanism 3 is arranged in the processing bin 12, and the slurry in the processing bin 12 can be fully mixed to ensure the quality and performance stability of the slurry. The detection mechanism 4 detects whether the performance value of the slurry in the processing bin 12 meets the design index, and the proportion of various components in the slurry can be timely discovered and adjusted to ensure that the performance of the slurry meets the design requirements, thereby meeting the needs of tunnel construction. When the performance value of the slurry meets the design index, the conveying mechanism 5 can convey the slurry in the processing chamber 12 to the grouting end of the shield machine 100, thereby performing synchronous grouting operations. Through the above-mentioned settings, the tunnel slag recycling system of the present application can achieve efficient and cyclic utilization of slag in shield construction, reducing environmental pollution and construction costs.

[0042] It should be noted that the grouting end of the shield machine 100 is the grouting system, which includes a control panel, a grouting pump and a grouting tank. Those skilled in the art are aware of the specific structure and working principle of the grouting end of the shield machine 100, which will not be repeated here.

[0043] The specific structure of the tunnel slag recycling system is described below:

[0044] Specifically, a pretreatment mechanism is provided in the storage bin 11, which is used to dry and screen the slag entering the storage bin 11 to remove excess moisture, large impurities and particles that do not meet the requirements in the slag, thereby ensuring the smooth progress of the subsequent processing process and the stability of the slurry quality.

[0045] The specific pretreatment process is as follows: first, the shield soil is dried at 105°C by hot air furnace, dryer and other equipment to remove excess water in the slag to prevent it from affecting the subsequent treatment effect and slurry performance, and then the slag is crushed by jaw crusher or impact crusher and other equipment, which has the advantages of high crushing efficiency and large processing capacity, and can refine the dried slag particles for subsequent screening, sorting and improvement treatment; then the slag is screened by vibrating screen, drum screen and other equipment, which has the advantages of simple structure, convenient operation and high screening efficiency. Among them, this embodiment uses a 2mm square hole screen to screen the slag, which can ensure that the obtained slag particles are uniform in size, thereby meeting the requirements of subsequent improvement treatment and grouting operations, and in other embodiments, a 4mm hole screen can be used to screen the slag, and the size of the sieve hole is not limited too much.

[0046] Specifically, the feeding mechanism 1 also includes a feeding assembly, which is configured to transport the debris in the storage bin 11 to the processing bin 12, so that the debris in the storage bin 11 can be accurately and efficiently transported to the processing bin 12, avoiding waste and pollution of the debris during transportation, and at the same time improving the overall operating efficiency of the entire system.

[0047] More specifically, in this embodiment, the feed assembly includes a slag box and / or a belt conveyor. The slag box can more conveniently collect and store the slag in the storage bin 11, which is convenient for unified management and subsequent processing. The belt conveyor can quickly and accurately transport the slag from the storage bin 11 to the processing bin 12, thereby improving the overall operating efficiency of the entire system. Moreover, those skilled in the art are aware of the specific structure and working principle of the slag box and the belt conveyor, which will not be described in detail here.

[0048] Specifically, the feeding mechanism 2 includes a curing agent bin, an admixture bin and a water storage bin, which are selectively connected to the processing bin 12, respectively, and can add key components such as curing agent, admixture and water to the processing bin 12, respectively, so that the tunnel slag recycling system can accurately adjust the addition amount of each component as needed, thereby forming a slurry with strong fluidity, self-compacting, good impermeability and controllable strength to meet the grouting requirements under different construction conditions. In addition, the feeding mechanism 2 also includes equipment well known in the art such as a metering pump or a screw feeder, and the addition of key components such as a curing agent, an admixture and water is achieved through the above equipment, so it is not repeated here.

[0049] More specifically, the curing agent of this embodiment adopts Baowu mineral powder-based curing agent, which uses Baowu blast furnace slag powder (GGBS) as the main raw material, fully utilizing its main components CaO, SiO2 and Al2O3, and can improve the strength and durability of the slurry. The admixture mainly includes mixed steel slag of multiple particle sizes, with a particle size range of 0 to 3 mm, which can improve the fluidity and working performance of the slurry, while improving the strength and durability of the slurry. Moreover, the tunnel slag recycling system uses industrial waste such as Baowu blast furnace slag powder and mixed steel slag as raw materials, which is conducive to the recycling of resources and environmental protection.

[0050] Specifically, the stirring mechanism 3 includes a stirring driver and a stirring assembly. The output end of the stirring driver is connected to the stirring assembly, which can drive the stirring assembly placed in the processing bin 12 to rotate, and can fully mix the components such as slag, curing agent, admixture and water in the processing bin 12 to ensure that the performance of the slurry meets the requirements. Among them, the stirring driver can adopt a variety of mechanical structures such as a motor, a hydraulic motor or a pneumatic motor. The stirring assembly includes a stirring shaft and a stirring blade. The stirring driver is connected to the stirring shaft and can drive the stirring shaft to rotate. The stirring blade is arranged on the stirring shaft and can fully mix the various components in the slurry during the rotation process, thereby improving the stirring efficiency and effect, meeting the needs of construction grouting, and reducing energy consumption and costs.

[0051] Specifically, the detection mechanism 4 includes a monitoring unit and a control unit. The monitoring unit is arranged in the processing chamber 12 and is communicatively connected to the control unit. The control unit can control the action of the conveying mechanism 5. The monitoring unit is used to collect key data about the slurry in the processing chamber 12, such as the temperature, humidity, density, viscosity and mixing ratio of each component of the slurry, and transmit these data to the control unit. The control unit then accurately controls the conveying mechanism 5 according to the preset algorithm and logical judgment, so as to convey the slurry whose performance value meets the design index to the shield machine 100.

[0052] More specifically, the monitoring unit includes a temperature sensor, a humidity sensor, a density sensor, and a viscosity sensor, which can monitor various performance indicators of the slurry (such as the temperature, humidity, density, viscosity of the slurry, and the mixing ratio of each component, etc.) in real time; the control unit includes a CPU or a PLC, and adopts control strategies such as PID control, fuzzy control, and neural network control. The above-mentioned components are mechanical components well known in the art, and no further restrictions are made on the specific structures of the above-mentioned components.

[0053] Specifically, the conveying mechanism 5 of this embodiment includes but is not limited to: a tunnel trolley, a screw conveyor and a pumping system, etc., and those skilled in the art are aware of the specific structure of the above-mentioned equipment and the specific principle of the control unit controlling the action of the conveying mechanism 5, so it will not be repeated here. In addition, the outlet end of the storage bin 11 is selectively connected to the processing bin 12 and the feeding mechanism 2 is selectively connected to the processing bin 12, which can be achieved through valve control structures such as solenoid valves and / or pneumatic valves, and no further explanation is given here.

[0054] like Figure 1 and Figure 2 As shown, this embodiment also provides a method for treating tunnel slag, which uses a tunnel slag recycling system to achieve efficient and recycled utilization of slag in shield construction, reducing environmental pollution and construction costs. The method for treating tunnel slag includes:

[0055] Step 1: transport the slag generated by the shield machine 100 during tunnel construction to the storage bin 11 .

[0056] In the above step 1, the present embodiment uses a screw conveyor to transport the slag excavated by the shield machine 100 to the storage bin 11. In other embodiments, the slag generated by the shield machine 100 during tunnel construction is transported to the storage bin 11 by a belt conveyor or other equipment to achieve centralized storage of the slag for subsequent processing. It is understandable that there is no excessive limitation on the specific transporting equipment, as long as the above-mentioned functions can be achieved.

[0057] Step 2: transport the slag in the storage bin 11 to the processing bin 12.

[0058] In the above step 2, the slag in the storage bin 11 is transported to the processing bin 12 through the slag box and the belt conveyor to provide raw materials for the preparation of slurry.

[0059] Step 3: Add filler into the processing chamber 12 through the adding mechanism 2 to form a slurry.

[0060] In the above step 3, the filler includes a curing agent, an admixture and water. Appropriate amounts of curing agent, admixture and water are added to the processing bin 12 through a metering pump or a screw feeder to form a slurry to improve the performance of the slag to meet the grouting requirements.

[0061] Among them, in this embodiment, the mixing ratio of slag is in the range of 40% to 45%, that is, the content of slag is moderate, which can provide enough solid particles to form a stable slurry structure and ensure that the slurry has good fluidity and plasticity; the mixing ratio of water is in the range of 27% to 32%, that is, the content of water is moderate, which can ensure that the slurry has sufficient fluidity for easy grouting and avoid the dilution and performance degradation of the slurry caused by excessive water; the mixing ratio of curing agent is 8%, which can ensure that the slurry has a good curing effect and avoid the cost increase and slurry performance degradation caused by excessive curing agent; the mixing ratio of admixture is 20%, which can increase the solid content of the slurry, thereby enhancing the strength and durability of the slurry. At the same time, the addition of admixtures can also improve the fluidity of the slurry, making it easier to grout. In other embodiments, the specific mixing ratio of the above components can be adjusted according to the needs of synchronous grouting, and no excessive restrictions are made here.

[0062] Step 4: Stir the slurry in the processing chamber 12 through the stirring mechanism 3.

[0063] In the above step 4, the stirring mechanism 3 is started to fully stir the slurry in the processing chamber 12 to ensure that the components are evenly mixed, so as to improve the uniformity and stability of the slurry and ensure the grouting effect.

[0064] Step 5: The detection mechanism 4 detects whether the performance value of the slurry in the processing chamber 12 meets the design index. If the performance value of the slurry meets the design index, the conveying mechanism 5 conveys the slurry whose performance value meets the design index to the grouting end of the shield machine 100. If the performance value of the slurry does not meet the design index, the filling mechanism 2 adds filler to the processing chamber 12 again until the performance value of the slurry meets the design index, and the conveying mechanism 5 conveys the slurry whose performance value meets the design index to the grouting end of the shield machine 100.

[0065] In the above step 5, the design index of the slurry performance can refer to the following contents: the permeability of the slurry, the change of slump over time, the yield strength, the pressure loss, the water bleeding rate, the stratification degree and the compressive strength, etc. The above design indexes can be used as an important basis for judging whether the slurry meets the construction requirements. The performance value of the slurry in the processing chamber 12 is monitored in real time by the monitoring unit, and the data is transmitted to the control unit. The control unit can accurately control the conveying mechanism 5 according to the preset algorithm and logical judgment. If the slurry performance value meets the design index, the slurry is conveyed to the grouting end of the shield machine 100 through the conveying mechanism 5 for grouting operation; if the slurry performance value does not meet the design index, an appropriate amount of filler is added to the processing chamber 12 again through the feeding mechanism 2, and the stirring and detection steps are repeated until the slurry performance value meets the design index, and then the conveying and grouting operation are carried out. Thereby ensuring that the performance of the grouting slurry meets the design requirements and improving the efficiency and safety of shield construction.

[0066] In addition, step five also includes the following steps:

[0067] Before the slurry is transported to the grouting end of the shield machine 100 , the slurry in the processing chamber 12 is re-stirred by the stirring mechanism 3 to ensure the uniformity and stability of the slurry, thereby meeting the requirements of the grouting operation.

[0068] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
