Abstract
Description
Technical Field
[0001] This application relates to the field of infrastructure construction technology, and in particular to an adjustable grouting hole flushing device. Background Technology
[0002] Grouting holes are channels drilled for injecting grout (cement grout, chemical grout, etc.). The grout penetrates and fills the fissures or pores in the strata to achieve purposes such as reinforcement, water plugging, and seepage prevention.
[0003] In existing technologies, grouting can be used for: foundation reinforcement (filling weak layers or fissures to improve bearing capacity, such as pile foundation reinforcement and sandy soil foundation treatment); seepage prevention and plugging (forming a seepage barrier, such as curtain grouting for dam foundations and tunnel water plugging); and structural repair (repairing concrete cracks or voids, such as bridge pier reinforcement). Depending on the technical problem being solved, the types of grouting holes drilled vary. They can be broadly categorized as curtain grouting holes, which are densely arranged along the structural axis to form a continuous seepage barrier, with a hole spacing of 1.5-3m and a row spacing of 1-2m, arranged in a quincunx pattern; and consolidation grouting holes, which are dispersed in the foundation to improve the integrity and strength of the rock mass, with a hole spacing of 2-5m, adjusted according to the degree of rock mass fissure development.
[0004] After drilling the grouting hole, a significant amount of drill cuttings will remain inside. Before grouting, the hole needs to be cleaned to remove the cuttings, sediment, and cracks, ensuring that water or grout can smoothly enter the cracks during pressure testing and grouting. However, because the hole diameter needs to be adjusted according to the type of grout (cement grout requires a larger diameter) and the formation permeability, typically varying between 50-110 mm, traditional cleaning methods are ineffective in removing drill cuttings and sediment, requiring more time and yielding poor cleaning results.

These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0020] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0022] To address the aforementioned issues, this application provides an adjustable grouting hole cleaning device. By incorporating a detachable cleaning structure, the device can adapt to cleaning different hole sizes while maintaining effective cleaning performance.
[0023] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.
[0024] See Figure 1The adjustable grouting hole flushing device includes a drive mechanism 1 and a cleaning gun connected to the drive mechanism 1. The cleaning gun includes a cleaning tube body 6 and a spraying mechanism. The spraying mechanism is rotatably mounted on the cleaning tube body 6. The cleaning tube body 6 includes a rotating shaft 2 and a cleaning structure connected to the rotating shaft 2. One end of the rotating shaft 2 is connected to the output shaft of the drive structure, and the other end is connected to the cleaning structure. The cleaning structure includes a sleeve 5, which is fixed to the rotating shaft 2 by screws. Cleaning plates 7 are evenly arranged on the outer circumference of the sleeve 5. The spraying mechanism is provided with bearings adapted to the rotating shaft 2 at both ends, and the spraying mechanism is rotatably mounted on the rotating shaft 2 through the bearings.
[0025] During operation, the grouting holes are purged by a spraying mechanism. Simultaneously, the cleaning plates 7 at the ends work. Multiple cleaning plates 7 are arc-shaped scrapers arranged circumferentially along the axis of the sleeve 5. Driven by the drive mechanism 1, the rotating shaft 2 is rotated. The cleaning plates 7 rotate under the drive of the rotating shaft 2, carrying out the purging slurry containing sediment and smoothing the irregular parts of the grouting holes. The drive mechanism 1 can be a three-phase motor or other drive motors that can be adapted to drive the rotating shaft 2. The spraying mechanism is rotatably mounted on the rotating shaft 2 via bearings to prevent the spraying device of the spraying mechanism from rotating and causing entanglement on the rotating shaft 2.
[0026] In some embodiments, the spraying mechanism includes an inner shell 4 and an outer shell 3. The outer shell 3 is disposed outside the inner shell 4, and there is a cavity structure between the inner shell 4 and the outer shell 3. The outer shell 3 is uniformly provided with outlet holes 8. An air filling pipe and a water filling pipe are respectively connected in the cavity structure between the inner shell 4 and the outer shell 3. The air filling pipe and the water filling pipe are respectively provided with branch hoses, and each different branch hose is connected to a different outlet hole 8.
[0027] During operation, compressed air is supplied to the air filling pipeline by an air pump, and water is continuously supplied to the water filling pipeline by a water pump. The grouting holes are purged using compressed air and high-pressure water. The outlet hole 8 can also be equipped with nozzles or spray heads as needed for air or water discharge operations.
[0028] The working process of this application:
[0029] First, drilling operations are carried out using mechanical equipment such as rotary drilling rigs and impact drills. During the operation, the verticality deviation is controlled to be ≤1%, and rock cores or returned slag are recorded to determine stratum changes. Then, a blowing operation is performed. The blowing device provided by this utility model is inserted into the drilled grouting hole. When the tube of the cleaning gun is inserted to a suitable depth, compressed air and high-pressure water are introduced by an air pump and a water pump, respectively, for blowing. Then, the air pump and water pump are turned off, and the drive mechanism 1 is turned on. The drive mechanism 1 drives the cleaning plate 7 to rotate and moves the entire blowing device outward. During this process, the cleaning plate 7 carries away the cleaned sediment and other debris, completing the blowing operation.
[0030] Finally, it should be noted that in this document, relationships such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "include," "contain," or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
