Description

Technical Field

[0001] The present application belongs to the technical field of grouting equipment, and in particular to a tunnel grouting device with adjustable pressure. Background Art

[0002] During the process of tunnel construction, tunnel projects often pass through a variety of geological structures, including weak rock layers, broken zones, faults, sandy soil layers, and areas rich in groundwater. These geological conditions increase the difficulty of tunnel excavation and support, and are prone to cause safety hazards such as landslides and water gushing. As a key component of infrastructure such as transportation and municipal administration, the safety and stability of roads are directly related to the safety of life and property. Therefore, effective measures must be taken to ensure the structural safety of tunnels during construction and operation. With the development of engineering technology, grouting technology has developed from traditional manual grouting to the current automated and intelligent grouting system, which can solve various problems in tunnel construction more accurately and efficiently. By injecting slurry to fill the gaps and cracks in the surrounding rock, the integrity and stability of the surrounding rock can be improved to prevent collapse, especially in loose, broken or water-containing strata. The most common tunnel grouting equipment currently available is a high-pressure grouting pump; a high-pressure grouting pump is a device used for grouting tunnels during construction, and it has been widely used in the field of tunnel construction.

[0003] When using the existing high-pressure grouting pump, first ensure that the high-pressure grouting machine and its accessories are intact, the oil level and filter are clean, and the appropriate type of hydraulic oil is selected. The grouting machine should be placed firmly and kept horizontal to avoid twisting and bending of the pipeline, shorten the length of the grouting pipe, mix cement, water and additives according to the design requirements, use a mixer to fully mix them, adjust the pressure setting, ensure that the initial pressure is low, gradually increase it to the design pressure, observe the system operation status, open the grouting valve, and start injecting slurry into the tunnel surrounding rock. It was found in the use of existing high-pressure grouting pumps that the grouting pumps are all at a constant pressure, which results in the pressure decreasing as the length of the pipeline laying increases during use, resulting in poor slurry fluidity. Therefore, the equipment has low working efficiency and poor practicality. Utility Model Content
