Description

Technical Field

[0001] The invention relates to the technical field of pipe jacking engineering construction, in particular to a self-priming pipe bottom sediment cleaning device and a cleaning method for a rock pipe jacking. Background Art

[0002] As an efficient trenchless construction method, rock jacking technology has been widely used because of its low environmental impact and high construction efficiency. In long-distance rock jacking construction, this technology often needs to pass through complex geological layers, such as moderately weathered sandy mudstone and strongly weathered muddy sandstone. The rock debris in these strata can easily enter the pipe wall during the excavation process to form slag accumulation. The formation of slag accumulation is affected by many factors, including over-excavation during construction, improper management of excavated materials, and unreasonable mud injection. For example, over-excavation can cause excavated materials to enter the pipe wall through the gap, while too low mud injection pressure or insufficient amount will affect the formation of mud jackets, further exacerbating the risk of slag accumulation.

[0003] Traditional methods of dealing with accumulated slag have significant shortcomings. These methods often require downtime and are inefficient, which not only seriously affects the construction progress, but also increases construction costs and risks. Especially in rock jacking construction, if accumulated slag is not cleaned up in time, it may cause pipe joints to get stuck, making it impossible for the jacking to advance normally, thus causing significant delays and economic losses to the entire project.

It should be understood that the terms used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein, for example.

[0040] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions.

[0042] It should be understood that the term "and / or" used in this disclosure is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone.

[0043] like Figure 1 to Figure 5 As shown, an embodiment of the technical solution of the present invention provides a rock top pipe self-priming pipe bottom sediment cleaning device, including: a slag cleaning main pipe 5, a pump station 2 and a slag sedimentation tank connected in sequence, and a controller 1.

[0044] At least one pipe section is provided on the slag cleaning main pipe 5, and the pipe section is connected to the slag cleaning branch pipe 6, so that the slag cleaning main pipe 5 and the slag cleaning branch pipe 6 are connected; the slag cleaning branch pipe 6 is provided with a valve 7 and a first solid flowmeter 8, the valve 7 is used to control the opening and closing of the slag cleaning branch pipe 6, and the first solid flowmeter 8 is used to monitor the accumulated slag flow in the slag cleaning branch pipe 6; the pump station 2 includes a self-priming pump and a second solid flowmeter 202, which are used to suck the accumulated slag 9 at the bottom of the slag cleaning branch pipe 6 through the slag cleaning branch pipe 6 and recover it through the accumulated slag sedimentation tank, and the second solid flowmeter 202 is used to monitor the accumulated slag flow in the pump station 2; the controller 1 is electrically connected to the valve 7, the first solid flowmeter 8, and the second solid flowmeter 202.

[0045] Specifically, the controller 1 receives flow signals from the first solid flow meter 8 and the second solid flow meter 202; if the accumulated slag flow rate of the first solid flow meter 8 or the second solid flow meter 202 is less than the flow threshold, the opening of the valve 7 is increased; if the accumulated slag flow rate of the first solid flow meter 8 or the second solid flow meter 202 is greater than the flow threshold, the opening of the valve 7 is reduced until it is closed. The opening of the valve 7 is adjusted according to the real-time data of the first solid flow meter 8 and the second solid flow meter 202, thereby improving the slag removal efficiency, reducing the personnel requirements at the construction site, and improving the construction safety and efficiency.

[0046] In this embodiment, preferably, a pressure sensor 201 is also provided on the pump station 2; the controller 1 is electrically connected to the pressure sensor 201 and the self-priming pump. The pressure sensor 201 is used to monitor the pressure value of the slag suction pipeline of the pump station 2. If the pressure in the slag suction pipeline is greater than the set threshold, the controller 1 controls the self-priming pump to reduce the suction force, and if the pressure in the slag suction pipeline is less than the set threshold, the controller 1 controls the self-priming pump to increase the suction force. Through the coordinated work of the self-priming pump and the pressure sensor 201 in the pump station 2, the suction force can be accurately regulated according to the real-time data in the slag cleaning process, effectively avoiding unnecessary waste of energy and equipment loss. Furthermore, the suction force in the pipeline can be increased after the valve 7 is closed, further improving the slag cleaning efficiency. The total amount of slag suction and the slag suction speed can also be measured by the first solid flowmeter 8 and the second solid flowmeter 202, which provides a reference for the setting of the self-priming pump.

[0047] Specifically, the self-priming pump includes a motor 205, a driven screw 203 and a driving screw 204. During the entire slag suction process, the slag suction direction is as follows: Figure 2 As shown in the direction of the middle arrow, the rotation speed of the motor 205 can realize the control of the suction force of the slag suction, and the pressure sensor 201 is used to monitor the pressure of the slag suction pipeline. When the pressure of the slag suction pipeline exceeds the set value, an alarm is issued to prevent the pipeline from bursting. If the pipeline pressure is too high, the rotation speed of the motor 205 can be reduced or stopped. If the pipeline pressure is too low, the rotation speed of the motor 205 is increased.

[0048] A reserved slag cleaning port 14 is provided at the bottom of the slag cleaning branch pipe 6 , and a connecting port 11 is provided between the slag cleaning branch pipe 6 and the reserved slag cleaning port 14 , which are connected by a first flange. The accumulated slag is sucked in through the reserved slag cleaning port 14 .

[0049] In this embodiment, the slag cleaning branch pipe 6 is preferably a detachable structure, and the slag cleaning branch pipe 6 is connected to the slag cleaning main pipe 5 through a second flange. A plurality of pipe sections are evenly distributed on the slag cleaning main pipe 5, so the slag cleaning main pipe 5 can be provided with one or more slag cleaning branch pipes 6. This avoids the difficulty of traditional cleaning methods in adapting to changes in different geological conditions and construction requirements, and can flexibly adjust the position and number of slag cleaning branch pipes 6 according to actual conditions, and can carry out targeted slag cleaning in different regions, ensuring the smooth progress of the slag cleaning process, and is suitable for rock jacking construction under various complex geological conditions.

[0050] Specifically, the first flange and the second flange include a connecting flange 1101, a bolt 1102, a nut 1103 and a compensation pad 1104. The slag cleaning branch pipe 6, the reserved slag cleaning port 14 and one end of the slag cleaning main pipe 5 are all equipped with a connecting flange 1101, and at least 8 flange holes 1106 for connection are also provided on the connecting flange 1101. A circular compensation pad 1104 is installed outside the flange hole 1106, and a through hole is provided in the center of the compensation pad 1104, and positioning grooves 1105 equal to the number of flange holes 1106 on the connecting flange 1101 are opened on the circumference. The diameter of these positioning grooves 1105 is slightly larger than the diameter of the bolt 1102, so that the bolt 1102 can pass through smoothly. When connecting, the bolt 1102 passes through the flange hole 1106 of the connecting flange 1101 and the positioning groove 1105 of the compensation pad 1104 in turn, and finally connects with the nut 1103, so that the various parts are tightly connected together.

[0051] In this embodiment, the valve 7 is preferably an electric valve 7, including an electromagnetic coil 701, a moving iron core 702, a signal receiver 703, a spring 704, a valve cover 705 and a valve body 706. The signal receiver 703 is responsible for receiving the control command of the controller 1, and then the electromagnetic coil 701 controls the opening and closing of the valve 7 according to the command to adjust the slag flow and pressure. Specifically, after the electromagnetic coil 701 is energized, a magnetic field is generated to attract the moving iron core 702 to overcome the resistance of the spring 704 and other resistances to open the valve 7; when the power is off, the magnetic field disappears, the moving iron core 702 is reset under the action of the spring 704, and the valve 7 is closed. The valve cover 705 and the valve body 706 are fastened by bolts 1102 to form a tight sealing structure to ensure the sealing performance of the valve 7 when it is closed.

[0052] The slag sedimentation tank includes a slag grinder 3, a conveyor belt 12 and a storage tank 13; the slag grinder 3 is connected to the pump station 2; the conveyor belt 12 connects the slag grinder 3 and the storage tank 13. Specifically, the slag first enters the crushing chamber 306 of the slag grinder 3. By starting the variable speed vibrator 301, the small bevel gear 302 and the large bevel gear 303 are driven to rotate, thereby inducing the vibration of the moving cone 305, so as to achieve effective grinding of the slag in the crushing chamber 306. The fixed cone 304 and the moving cone 305 work together to form a part of the crushing chamber 306. During the grinding process, the vibration of the moving cone 305 will cause the gap between it and the fixed cone 304 to change continuously, so that the slag entering the crushing chamber 306 is effectively ground into particles of the required particle size. The spherical bearing 307 connects the moving cone 305 and the main shaft 309, which can withstand large radial and axial loads and has a certain self-aligning ability. It can maintain stable operation when bearing complex and variable loads, thereby ensuring the overall performance and grinding effect of the slag grinding machine 3. The eccentric sleeve 308 is installed on the main shaft 309 and is connected to the variable speed vibrator 301. When the variable speed vibrator 301 is started, it drives the eccentric sleeve 308 to produce periodic vibration, thereby driving the moving cone 305 to vibrate. The design of the eccentric sleeve 308 allows the vibration trajectory and frequency of the moving cone 305 to be precisely controlled, thereby achieving precise adjustment of the slag grinding effect. The main shaft 309 transmits the power of the variable speed vibrator 301 to the moving cone 305 and supports the weight of the entire crushing chamber 306 and the moving cone 305. By adjusting the frequency and vibration duration of the variable speed vibrator 301, the particle size of the slag after grinding can be precisely controlled to meet the needs of subsequent reuse. The ground slag is then transported to the storage tank 13 via the conveyor belt 12 for storage.

[0053] In this embodiment, a jacking head 4 is also provided at the end of the slag cleaning main pipe 5 for advancing during rock jacking construction. The pipe section and the slag cleaning branch pipe are located behind the jacking head 4 to form a jacking construction pipeline.

[0054] In this embodiment, the controller 1 is arranged in the data control console, which mainly includes a central processing unit, a data processing terminal, a controller 1, a display system and an alarm system. The central processing unit plays a core role in the data control console, and is responsible for parameter setting, monitoring process, and flexible control of the valve 7 to adapt to different construction requirements. At the same time, it supports the switching between automatic and manual slag removal modes, and processes sensor data to adjust the strategy and issue an alarm in real time to ensure efficient and stable operation of slag cleaning. The data processing terminal monitors the progress of the entire slag suction cleaning process and the changes of related data in real time. The remote control console can fully control the entire process of slag cleaning. The display system is for the staff to set the parameters, valve 7 switch and slag suction mode in the slag cleaning process, and monitor the entire slag suction cleaning process and data changes. The equipment control program controls the entire slag cleaning process. According to actual needs, the valve 7 switch is flexibly adjusted to adjust the position and amount of slag removal to adapt to different geological conditions and construction requirements. At the same time, slag removal is divided into two functions: automatic slag removal and manual slag removal. The automatic slag removal mode is selected for general geological conditions, and when crossing the formation fracture zone, water-rich formation, etc., it is necessary to select a more flexible manual grouting according to construction needs to perform single-area selective slag removal.

[0055] In this embodiment, the controller 1 and the pump station 2 , and the controller 1 and the valve 7 are electrically connected via control cables 10 , respectively.

[0056] According to a second aspect of the technical solution of the present invention, there is provided a cleaning method of the rock top pipe self-priming pipe bottom sediment cleaning device of the above embodiment, comprising:

[0057] S1, start the device and initialize the controller 1;

[0058] S2, open valve 7 and self-priming pump, suck the slag 9 at the bottom of the pipe into the slag cleaning branch pipe 6, and then enter the slag sedimentation tank through the slag cleaning main pipe 5 and pump station 2;

[0059] S3, the slag sedimentation tank grinds and stores the slag.

[0060] Step S1 includes: ensuring the normal operation of the controller 1 and the pump station 2, the controller 1 starts to monitor the initial states of the valve 7, the first solid flow meter 8, the second solid flow meter 202, the pressure sensor 201 and the self-priming pump.

[0061] Step S2 includes:

[0062] The controller 1 receives flow signals from the first solid flow meter 8 and the second solid flow meter 202; if the accumulated slag flow rate of the first solid flow meter 8 or the second solid flow meter 202 is less than the flow threshold, the opening of the valve 7 is increased; if the accumulated slag flow rate of the first solid flow meter 8 or the second solid flow meter 202 is greater than the flow threshold, the opening of the valve 7 is reduced until it is closed; if the accumulated slag flow rate of the first solid flow meter 8 or the second solid flow meter 202 is equal to the flow threshold, the opening of the valve 7 remains unchanged;

[0063] The self-priming pump is provided with a pressure sensor 201, and the controller 1 is electrically connected to the pressure sensor 201 and the self-priming pump. The controller 1 receives the pressure signal of the pressure sensor 201; if the pressure of the pressure sensor 201 is greater than the pressure threshold, the suction of the self-priming pump is reduced; if the pressure of the pressure sensor 201 is less than the pressure threshold, the suction of the self-priming pump is increased; if the pressure of the pressure sensor 201 is equal to the pressure threshold, the suction of the self-priming pump remains unchanged. Preferably, the suction of the self-priming pump is adjusted by adjusting the rotation speed of the motor 205.

[0064] In step S3 , the slag sedimentation tank grinds the slag and transfers it to the storage tank 13 via the conveyor belt 12 .

[0065] The method further includes: when the accumulated slag flow rates of the first solid flow meter 8 and the second solid flow meter 202 are both less than the flow threshold, the slag cleaning is completed, the valve 7 is closed, and the slag suction operation is stopped, and the suction force in the pipeline can be increased after the valve 7 is closed. When all the accumulated slag is transferred to the storage tank 13, the pump station 2 and the controller 1 are closed, and each component is maintained and cleaned.

[0066] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0067] The serial numbers of the above embodiments of the present invention are only for description and do not represent the advantages or disadvantages of the embodiments.

[0068] Through the description of the above implementation methods, those skilled in the art can clearly understand that the above implementation method can be implemented by means of software plus a necessary general hardware platform, and of course, it can also be implemented by hardware, but in many cases the former is a better implementation method.
