Description

Technical Field

[0001] The invention relates to the technical field of underground deep deformation monitoring, in particular to a sand and gravel cleaning device in an inclinometer hole. Background Art

[0002] In large-scale water conservancy and hydropower projects, road projects and other infrastructure projects, deformation monitoring work is required to ensure the stability of key parts and slopes during the construction and operation stages, and the monitoring work runs through the entire construction cycle of the project and the final operation period to provide data support for the stability of the slope. At present, similar monitoring projects are carried out in the form of surface deformation monitoring + deep deformation monitoring. Inclinometer monitoring is an indispensable means of deep monitoring, which mainly involves drilling holes in the deformed parts. After the drilling is completed, the inclinometer tube is inserted, and then the relevant monitoring equipment is buried in the inclinometer tube for regular observations to accurately judge the deep underground deformation of the part. However, after the deep monitoring borehole is completed, during the process of inserting the inclinometer tube, since the length of each tube is 2 to 3 meters and the hole depth varies from dozens of meters, during the process of connecting and placing the inclinometer tube, due to geological structure reasons or collision of the inclinometer tube during installation, sand and gravel will inevitably fall into the hole, causing hole blockage. This requires timely cleaning of the sand and gravel that have fallen into the hole. In the past, the cleaning work was carried out by blowing the hole with an air compressor. However, this method not only requires large equipment such as air compressors and air ducts, but also requires more manpower and material resources to cooperate with the heavy equipment to complete this work. In view of the problems of large personnel investment and long time consumption in the existing method, it is urgent to develop a sand and gravel cleaning device in the inclinometer hole, which only requires one person to solve the problem of cleaning the sand and gravel in the hole when the inclinometer tube is installed each time. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a device for cleaning sand and gravel in an inclinometer hole, comprising a collecting tube and a control rod, wherein the upper end of the collecting tube is connected to the lower end of the control rod, and the lower end of the collecting tube is connected to the upper end of a drill bit, and the three are coaxial; the collecting tube is a hollow cylinder, and a rectangular window is provided on its side, and a collecting bin is formed inside the collecting tube within the rectangular window; the drill bit is an inverted cone, and its upper end face is fixedly connected to the lower end face of the collecting tube, and the upper end face of the drill bit matches the cross-section of the collecting tube.

[0004] Furthermore, a scraping tooth is provided on the right side of the rectangular window, and the tooth tip of the scraping tooth protrudes 2-3 mm from the outer wall of the collecting tube.

[0005] Furthermore, a first screw is provided at the center of the upper end surface of the collecting cylinder, a thread hole is provided at the center of the lower end surface of the control rod, and the first screw is cooperatively connected with the thread hole.

[0006] Furthermore, a spiral groove is provided on the outer wall of the drill bit, and a collecting chamber is provided on the upper part of the drill bit, and the collecting chamber is communicated with the collecting bin.

[0007] Furthermore, a second screw is provided at the upper end of the control rod, and the second screw can be connected with the thread hole.

[0008] The beneficial effects of the utility model are:

[0009] After the device is assembled, the staff holds the control lever and lowers the collecting tube and the drill bit arranged thereunder to the blocking position in the inclinometer hole. By rotating the control lever, the drill bit loosens the sand and gravel blocking the hole under the action of rotation, and the scraping teeth arranged on the side of the collecting tube scrape the sand and gravel into the collecting bin. The collecting tube is lifted to the surface and dumped to achieve the purpose of sand and gravel cleaning. The device has a simple structure, is convenient and portable, saves manpower, and generates economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Embodiment 1, as shown in the figure, is a sand and gravel cleaning device in an inclinometer hole, comprising a collecting barrel 1 and an operating rod 2, wherein the upper end of the collecting barrel 1 is connected to the lower end of the operating rod 2, and the lower end of the collecting barrel 1 is connected to the upper end of a drill bit 3, and the three are coaxial. When cleaning sand and gravel, since the collecting barrel 1, the drill bit 3 and the operating rod 2 are coaxial, when the operating rod 2 is rotated, the collecting barrel 1 and the drill bit 3 will also rotate coaxially, making the rotation smoother; the collecting barrel 1 is a hollow cylinder, and a rectangular window 11 is provided on its side, and a collecting bin 12 is formed inside the collecting barrel 1 within the rectangular window 11; the drill bit 3 is an inverted cone, and its upper end face is fixedly connected to the lower end face of the collecting barrel 1, and the upper end face of the drill bit 3 matches the cross section of the collecting barrel 1.

[0016] In this embodiment, a scraper tooth 13 is provided on the right side of the rectangular window 11, and the tooth tip of the scraper tooth 13 protrudes 2-3mm from the outer wall of the collecting cylinder 1; a first screw rod 14 is provided at the center of the upper end surface of the collecting cylinder 1, and a thread hole 21 is provided at the center of the lower end surface of the control rod 2, and the first screw rod 14 is cooperated and connected with the thread hole 21; in this scheme, the scraper tooth 13 is arranged on the right side of the rectangular window 11, and the collecting cylinder 1 is connected to the control rod by thread connection, and a conventional positive thread connection is adopted, so that when the staff habitually rotates the control rod 2 clockwise, the drill bit 3 will also drill in the clockwise direction, and the scraper tooth 13 facing the clockwise direction can also play the role of scraping sand and gravel into the collecting bin 12. At the same time, the tooth tip of the scraper tooth 13 protrudes 2-3mm from the outer wall of the collecting cylinder 1 to facilitate scraping sand and gravel into the collecting bin 12. In the above operation, due to the clockwise rotation, the connection between the collecting cylinder 1 and the control rod 2 will not be detached.

[0017] In this embodiment, the outer wall of the drill bit 3 is provided with a spiral groove 31. This design is that when the drill bit 3 rotates, the sand and gravel will float along the spiral groove 31, and the sand and gravel can be collected into the collection bin 12 more easily. A collection chamber 32 is provided on the upper part of the drill bit 3, and the collection chamber 32 is communicated with the collection bin 12. The advantage is that when cleaning the clogged part of the inclinometer hole, the amount of sand and gravel collected in a single time is increased.

[0018] In this embodiment, a second screw 22 is provided at the upper end of the control rod 2, and the second screw 22 can be connected with the wire hole 21. Since the depth of the inclinometer hole is generally between 20-30 meters, the length of the control rod 2 in this scheme is between 2-3 meters. When clearing the inclinometer hole with a depth of 20-30 meters, multiple control rods 2 need to be connected end to end before cleaning can be carried out. Therefore, there is a design in which the wire hole 21 and the second screw 22 are respectively provided at both ends of the control rod 2, and when the first screw 14 provided at the center of the upper end surface of the collecting cylinder 1 is replaced with a wire hole of the same size as the wire hole 21, the control rod 2 is also suitable for connection with the collecting cylinder 1, or connection between control rods 2.

[0019] In the above embodiment, the collecting tube 1 and the drill bit 3 can be made of stainless steel, which has the advantage of being rust-proof and can be reused for a long time, while the control rod 2 is made of a lighter magnesium-aluminum alloy material, which is convenient to carry and reduces the weight for the staff.

[0020] Method of use of the utility model;

[0021] When installing the inclinometer tube in the inclinometer hole, if the inclinometer hole is blocked, the staff will assemble the multi-section control rod 2 according to the depth of the blockage position, and then connect the collecting tube 1 connected with the drill bit 3 to the first section of the control rod 2. The staff will hold the control rod 2 and lower the collecting tube 1 and the drill bit 3 connected thereto to the blocked hole position in the inclinometer hole. By rotating the control rod, the drill bit 2 will loosen the blocked sand and gravel in the hole under the action of rotation, and the scraping teeth arranged on the side of the collecting tube 1 will scrape the sand and gravel into the collecting bin. The collecting tube will be lifted out of the ground and dumped. After repeated operations until the blocked sand and gravel are cleared, the next step of installing the inclinometer tube can be carried out.

[0022] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
