Description

Technical Field

[0001] The invention belongs to the technical field of waterproof engineering, in particular to a pressure grouting automatic control device for repairing water leakage. Background Art

[0002] Leakage is a persistent and common quality issue in housing construction, making it difficult to address. Leaks frequently occur in basements, bathrooms, roofs, and other areas. While this is often due to poor waterproofing construction, it's more importantly due to the failure of the concrete's inherent waterproofing, characterized by cracks and other loose structures within the concrete structure. Repairing leaks is particularly challenging, especially in basements where head pressure is high.

[0003] Therefore, the known waterproof leakage repair method has the above-mentioned inconveniences and problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a safe and reliable pressure grouting automatic control device for water leakage repair.

[0005] To achieve the above objectives, the technical solution of the present invention is: A pressure grouting automatic control device for water leakage repair, comprising a grouting vehicle, characterized in that: The grouting vehicle is a four-wheeled flatbed vehicle, with a grouting pump on the top and a pressure controller in the middle of the vehicle. One side of the grouting pump is connected to the grouting needle through a grouting pipe, and the other side of the grouting pump is connected to the grouting liquid storage through a conduit. A pressure gauge is provided in the grouting pipe. Among them, the grouting pump and the pressure controller are connected through a signal transmission line, and the control signal is transmitted to the grouting pump in real time according to the slurry pressure at the output end, so as to control the operation of the grouting pump and thus adjust the grouting pressure value; the grouting pipe is also connected to the pressure controller through the grouting liquid line pipe, and the pressure value is fed back to the pressure controller, and the grouting liquid is pressurized and pressed into the structure that needs to be repaired through the grouting pipe.

[0008] The aforementioned automatic pressure grouting control device for water leakage repair, wherein the pressure controller is provided with a built-in pressure sensor, which monitors the pressure changes in the system in real time and compares them with the set value. When the actual pressure reaches or exceeds the set value, the pressure controller will trigger the corresponding control action, cut off the power supply of the grouting pump, and stop it from running to maintain the stability of the system pressure; when the pressure value is lower than the set value, the power supply is turned on, so that the grouting pump is restarted and the system pressure rises.

[0012] Figure 1 This is a schematic structural diagram of an automatic pressure grouting control device according to an embodiment of the present invention; Figure 2 This is a schematic diagram of the automatic control principle of pressure grouting according to an embodiment of the present invention. DETAILED DESCRIPTION

[0013] The present invention will be further described below with reference to the embodiments and the accompanying drawings.

[0014] Example 1 The pressure grouting automatic control device for water leakage repair of the present invention comprises a grouting vehicle.

[0015] Please refer to Figure 1 and Figure 2The grouting equipment is carried by a grouting vehicle 1, a four-wheeled flatbed truck. The grouting pump, pressure controller, and other equipment are mounted on the vehicle, connected to an external power source and grouting fluid. The pressurized grouting fluid is then pumped through the grouting pipe into the structure requiring repair. A grouting pump 2 is mounted on the vehicle, and the pressurized grouting fluid is pumped out. A signal transmission line 3 connects the pressure controller to the grouting pump, transmitting a control signal to the grouting pump in real time based on the slurry pressure at the output end, thereby controlling the operation of the grouting pump and adjusting the grouting pressure. The pressure controller 4 can set a control range for the grouting pressure, sensing the output grouting pressure in real time and adjusting the grouting pressure within the control range by controlling the operation of the grouting pump. As a key component in this system, the pressure controller's operating principle is primarily based on sensing and regulating pressure. A built-in pressure sensor monitors pressure changes within the system in real time and compares them with a set value. When the actual pressure reaches or exceeds the set value (the upper pressure limit for this system is 20 MPa), the controller triggers a corresponding control action, shutting off the power to the grouting pump and causing it to stop operating to maintain stable system pressure. When the pressure value is lower than the set value (the lower limit of the grouting pressure of this system is 5MPa), turn on the power so that the grouting pump restarts and the system pressure rises. The grouting liquid line pipe 5 connects the grouting pipe and the pressure controller, and feeds the pressure value back to the pressure controller. The pressure gauge 6 can observe the actual output pressure in real time. The grouting pipe 7 connects the grouting pump and the grouting needle, and transports the high-pressure grouting liquid to the grouting needle until it reaches the inside of the structure. The grouting needle is driven into the interior of the structure to transport the grouting liquid into the cracks of the structure. The grouting liquid storage device can temporarily store the adjusted slurry to be injected, and is connected to the grouting pump through a conduit. The conduit 10 connects the grouting liquid storage device and the grouting pump.

[0016] Example 2 The method of using the automatic pressure grouting control device for water leakage repair of the present invention: (1) Find the leakage site of the wall or board and determine whether pressure grouting is needed for leakage repair. Drill a hole every 25 to 30 cm, and the drilling depth must reach 1 / 2 of the thickness of the structure. Insert the grouting needle into the drilled hole and screw it in with a wrench until it reaches the bottom of the hole. After completing a batch, wait for grouting construction.

[0017] (2) The pressure grouting equipment is in place and connected to the power supply; (3) Prepare the grouting fluid according to the leakage treatment plan and temporarily store it in the storage device; (4) One end of the grouting pump is connected to the grouting liquid storage through a catheter, and the output end is connected to the grouting needle through a high-pressure grouting pipe (5) Start the grouting pump to inject high-pressure liquid into the structure, and the pressure controller controls the grouting pressure in real time.

[0018] The present invention has substantial characteristics and significant technological advancements. The pressure grouting automatic control device for water leakage repair of the present invention can set the grouting pressure value and automatically control the grouting pressure to ensure that the grouting liquid can be smoothly injected into the structural entity without being unable to be injected due to too low pressure or causing structural damage and other risks due to excessive pressure. In the leakage repair construction, automatic control of pressure grouting is achieved, which improves construction efficiency. Compared with the existing method of manually controlling the operation of the pressure pump through the start-stop switch to adjust the grouting pressure, the grouting pressure control of the automatic pressure control device of the present invention is more precise and can be adjusted according to different leakage repair environments, providing a reliable guarantee for achieving better leakage repair results.

[0019] The above embodiments are intended to illustrate the present invention only and are not intended to limit the present invention. Persons skilled in the art may make various modifications or variations without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions are intended to fall within the scope of the present invention and are defined by the claims.
