Technical Field
[0001] The invention relates to the technical field of bolter hole cleaning, and in particular to a sand bailing barrel used for wet bolter hole cleaning. Background Art
[0002] Due to environmental protection and other requirements, small-volume rock anchor foundations and micro-pile foundations have been widely used in transmission line projects in recent years. Traditional construction uses down-the-hole drills and air compressors to form anchors and micro-foundation pits. This method produces a lot of dust and causes great damage to the health of construction workers and the natural environment. When using a wet anchor machine to excavate rock anchors and micro-pile foundations, there is a problem that the residue is difficult to clean up. Using water flushing or Luoyang shovels to take soil is not efficient. Summary of the invention
[0003] The technical problem to be solved and the technical task proposed by the present invention are to improve and perfect the existing technical solutions and provide a sand bailing barrel for cleaning holes of wet anchor bolters to improve the cleaning efficiency of anchor bolt holes. To this end, the present invention adopts the following technical solutions.
[0004] A sand bailing barrel for a wet anchor bolter hole cleaning includes a slag collecting bucket, a standard pipe section and a connector. The bottom end of the slag collecting bucket is provided with an insertion section for inserting into the anchor bolt hole residue. The middle of the slag collecting bucket is provided with a water pipe section coaxial with the slag collecting bucket. The water pipe section is connected to the insertion section, the middle is a flushing hole, the lower end of the insertion section is a flushing port, and the upper end of the water pipe section can be connected in series with a plurality of standard pipe sections through a connector. The wet anchor bolter hole cleaning sand bailing barrel structure integrates a slag collecting bucket, a standard pipe section and a connector. The slag collecting bucket is used to collect the anchor bolt hole residue flushed out by water pressure, and the combination of the standard pipe section and the connector allows the user to adjust the length of the sand bailing barrel as needed to adapt to anchor bolt holes of different depths, which can effectively improve the hole cleaning efficiency and enhance the flexibility and adaptability of the sand bailing barrel.
[0005] As a preferred technical means: the bottom and side of the slag collecting bucket are provided with water filter holes, and the upper end of the slag collecting bucket is open. The water filter holes are arranged at the bottom and side of the slag collecting bucket, so that during the flushing process, water can be discharged through the water filter holes, while the residue is retained in the slag collecting bucket, which helps to quickly separate water and residue and improve the hole cleaning effect. At the same time, the design of the upper end of the slag collecting bucket is open to facilitate the collection and cleaning of residues.
[0006] As a preferred technical means: the lower end of the insertion section adopts an oblique structure, so that the sand bailing tube is easier to insert into the residue at the bottom of the anchor hole.
[0007] As a preferred technical means: the connector adopts a straight internal thread structure, and the upper end of the water pipe section and the upper and lower ends of the standard pipe section adopt external threads that match the internal threads of the connector. The threaded connection method facilitates the assembly and disassembly of the various components, so that the sand bailing barrel can flexibly increase or decrease the standard pipe sections when in use to adapt to the needs of cleaning anchor holes of different depths, and the connection is stable, which ensures the stability of the sand bailing barrel structure during the hole cleaning operation and is conducive to efficient hole cleaning.
[0008] As a preferred technical means: the slag collecting bucket adopts a cylindrical shell structure, and the upper end of the shell is open. The cylindrical structure is easy to manufacture and the force is relatively uniform when inserted into the circular anchor hole. The open design facilitates the slag to enter the slag collecting bucket for collection. The overall structure is simple and practical, which meets the requirements of the hole cleaning operation for the slag collecting bucket function and ease of use, and helps to better collect the slag and improve the hole cleaning efficiency.
[0009] As the preferred technical means: the diameter of the slag bucket is in the range of 80-100mm, the height is in the range of 400-450mm, the wall thickness is in the range of 2.2-2.8mm, the diameter of the water pipe section and the standard pipe section is in the range of 25-30mm, the wall thickness is in the range of 2.2-2.8mm, the end thread height of the water pipe section and the standard pipe section is in the range of 20-25mm, and the length of the standard pipe section is in the range of 900-1100mm. The size is reasonably optimized and can adapt to most common construction scenes such as rock anchor foundations and micro pile foundations, ensuring that the sand bailing barrel can play a better role in clearing holes under different working conditions, improving the versatility and practicality of the sand bailing barrel and improving the efficiency of hole clearing.
[0010] As a preferred technical means: the upper end of the water pipe section is at least 30 mm higher than the upper end of the slag collecting bucket. This dimension is higher than the thread height of the standard pipe joint, and the tool will not touch the slag collecting bucket when connecting the standard pipe joint, making the connection more convenient.
[0011] As the preferred technical means: the slag bucket, standard pipe section and connector are all made of steel, and the standard pipe section, water pipe section and insert section are connected by welding. The overall structural strength of the sand bailing tube is guaranteed, so that it can withstand various external forces in the hole cleaning operation and is durable; the standard pipe section, water pipe section and insert section are connected by welding, so that the connection of each part is firm and reliable, avoiding the problems of loosening and falling of parts during the hole cleaning process, ensuring that the sand bailing tube can perform the hole cleaning work stably and effectively, and improving the hole cleaning efficiency and quality.
[0012] As a preferred technical means: the water pipe section and the insertion section are the same steel pipe, which can reduce the number of connection parts, avoid water leakage and structural instability that may occur at the connection points, and ensure the smoothness of the flushing function and the reliability of the entire sand bailing tube structure in the hole cleaning operation.
[0013] Beneficial effects: The bailing barrel can be conveniently inserted into the residue at the bottom of the anchor hole, and the slag collecting bucket can conveniently collect the anchor hole residue flushed out by water pressure, while the combination of standard pipe sections and connectors allows the user to adjust the length of the bailing barrel as needed to adapt to anchor holes of different depths, which can effectively improve the hole cleaning effect and efficiency, enhance the flexibility and adaptability of the bailing barrel, and significantly speed up the hole cleaning speed. BRIEF DESCRIPTION OF THE DRAWINGS
[0014] Figure 1 It is a schematic diagram of the structure of the present invention.
[0015] In the figure: 1. slag collecting bucket; 2. standard pipe joint; 3. connecting piece; 101. insertion section; 102. water pipe section. DETAILED DESCRIPTION
[0016] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings.
[0017] like Figure 1 As shown, a sand bailing barrel for wet anchor machine hole cleaning comprises a slag collecting bucket 1, a standard pipe section 2 and a connecting piece 3. The bottom end of the slag collecting bucket 1 is provided with an insertion section 101 for inserting into the anchor hole residue to collect the anchor hole residue flushed out by water pressure. The slag collecting bucket 1 adopts a cylindrical shell structure, and the upper end of the shell is open. A water pipe section 102 coaxial with the slag collecting bucket 1 is provided in the middle of the slag collecting bucket 1. The water pipe section 102 is connected to the insertion section 101, and the middle is a flushing hole. The lower end of the insertion section 101 is a flushing port. The upper end of the water pipe section 102 can be connected in series through the connecting piece 3 to increase the standard pipe section 2, and the standard pipe section 2 can also be continuously connected through the connecting piece 3 to increase the standard pipe section 2. The connection combination of the standard pipe section 2 and the connecting piece 3 allows the user to adjust the length of the sand bailing barrel as needed, thereby enhancing the flexibility of the sand bailing barrel to adapt to anchor holes of different depths, and can effectively improve the hole cleaning efficiency.
[0018] In order to separate water and residue, the bottom and sides of the slag collecting bucket 1 are provided with water filtering holes, and the upper end of the slag collecting bucket 1 is open. The water filtering holes are arranged at the bottom and sides of the slag collecting bucket 1, so that during the flushing process, water can be discharged through the water filtering holes, while the residue is retained in the slag collecting bucket 1, which helps to quickly separate water and residue and improve the hole cleaning effect. At the same time, the design of the upper end of the slag collecting bucket 1 is open to facilitate the collection and cleaning of the residue.
[0019] In order to make it easier for the sand bailing tube to be inserted into the residue at the bottom of the anchor hole, the lower end of the insertion section 101 adopts an oblique structure. In this example, the total length of the insertion section 101 is 60 mm, of which the axial length of the oblique structure is 26 mm. The oblique structure has a small end area, making it easier for the sand bailing tube to be inserted into the residue at the bottom of the anchor hole.
[0020] In order to facilitate the disassembly and assembly of the standard pipe section 2 to meet the requirements of anchor hole cleaning at different depths, the connector 3 adopts a straight internal thread structure, and the upper end of the water pipe section 102 and the upper and lower ends of the standard pipe section 2 are both external threads that match the internal threads of the connector 3. The threaded connection method facilitates the assembly and disassembly of the various components, so that the sand bailing barrel can flexibly increase or decrease the standard pipe section 2 when in use to meet the requirements of anchor hole cleaning at different depths, and the connection is stable, which ensures the stability of the sand bailing barrel structure during the hole cleaning operation and is conducive to efficient hole cleaning.
[0021] In order to make the sand bailing tube durable, the slag collecting bucket 1, standard pipe section 2 and connecting piece 3 are all made of steel, and the standard pipe section 2, water pipe section 102 and insert section 101 are connected by welding. The overall structural strength of the sand bailing tube is guaranteed, so that it can withstand various external forces in the hole cleaning operation and be durable; the standard pipe section 2, water pipe section 102 and insert section 101 are connected by welding, so that the connection of each part is firm and reliable, avoiding the problems of loosening and falling of parts during the hole cleaning process, ensuring that the sand bailing tube can perform the hole cleaning work stably and effectively, and improving the hole cleaning efficiency and quality.
[0022] In order to reduce the number of connection parts, the water pipe section 102 and the insertion section 101 are the same steel pipe, which can reduce the number of connection parts, avoid water leakage and structural instability that may occur at the connection points, and ensure the smoothness of the flushing function and the reliability of the entire sand bailing tube structure in the hole cleaning operation.
[0023] In this example, the diameter of the slag bucket 1 is 90mm, the height is 420mm, the wall thickness is 2.5mm, the diameter of the water pipe section 102 and the standard pipe section 2 is 26mm, the end external thread is M26, the wall thickness of the water pipe section 102 and the standard pipe section 2 is 2.5mm, the end thread height of the water pipe section 102 and the standard pipe section 2 is 20mm, and the length of the standard pipe section 2 is 1000mm. The size is reasonably optimized and can adapt to most common construction scenes such as rock anchor foundations and micro pile foundations, ensuring that the sand bailing tube can play a good role in clearing holes under different working conditions, improving the versatility and practicality of the sand bailing tube and improving the efficiency of hole clearing.
[0024] In this example, the upper end of the water pipe section 102 is at least 30 mm higher than the upper end of the slag collecting bucket 1, which is higher than the thread height of the standard pipe section 2. When connecting the standard pipe section 2, the tool will not touch the slag collecting bucket 1, making the connection more convenient. The total length from the upper end of the water pipe section 102 to the lower end of the insertion section 101 is 1000 mm.
[0025] In this example, the connector 3 has a diameter of 32 mm, a wall thickness of 3 mm, and internal threads 20 mm long at both ends for connection.
[0026] Before the wet anchor bolter hole cleaning operation is carried out, first check whether the various parts of the sand bailing tube are intact, ensure that the connection threads between the water pipe section 102, the standard pipe section 2 and the connector 3 of the slag collecting bucket 1 are not damaged, and the welding parts are firm and reliable. At the same time, prepare external equipment such as a pump and connect it to the upper end of the sand bailing tube. Insert the insertion section 101 at the bottom of the slag collecting bucket 1 of the sand bailing tube into the residue in the anchor hole. Start the pump, pump water into the steel pipe composed of the water pipe section 102 and the standard pipe section 2, and flush it out from the flushing port at the lower end of the insertion section 101. The strong water pressure and the narrow space in the anchor hole enable the water discharged from the flushing port to better flush out the residue at the bottom, surge upward, and the residue falling into the slag collecting bucket 1 when descending can be smoothly collected. When a certain amount of residue is collected in the slag collecting bucket 1, the sand bailing tube is lifted out of the anchor hole, and the residue in the slag collecting bucket 1 is cleaned. It can be cleaned manually or with the help of other tools. After cleaning, the bailing tube is inserted into the anchor hole again, and the above process of flushing water to clean the hole and collecting residues is repeated until the cleaning operation of the entire anchor hole is completed.
[0027] The sand bailing barrel for cleaning holes of a wet anchor bolter shown above is a specific embodiment of the present invention, which has embodied the outstanding substantial features and remarkable progress of the present invention. According to actual use needs and under the guidance of the present invention, equivalent modifications in shape, structure, etc. can be made to it, which are all within the protection scope of this scheme.
