Description

Technical Field

[0001] The utility model belongs to the technical field of acoustic detection pipes, and in particular relates to a recyclable acoustic detection pipe anti-blocking protection device. Background Art

[0002] In recent years, with the development of my country's urban rail transit industry, the use of bored piles, underground continuous walls, etc. as soil support around subway stations, tunnels and tunnel entrances, as well as structural base engineering piles, is a relatively common support and reinforcement engineering technology. It can play a certain supporting, isolating and load-resistant function. It is widely used in subway construction and construction projects. In pile foundation detection, the pile body integrity detection mostly adopts the acoustic wave transmission method, and the acoustic detection tube is pre-buried in the steel cage as the ultrasonic detection channel. The acoustic detection tube is very easy to be damaged during the construction of bored piles and underground continuous walls before the detection, resulting in the inability to carry out the detection work normally. This patent is mainly aimed at the rubber gasket compression and sealing device adopted during the excavation of the foundation pit of the tunnel project and the removal of the bored pile head and the ground-connected wall head, which can easily damage the acoustic detection tube, causing external soil and gravel to enter the acoustic detection tube and affect the normal detection of the pile foundation.

[0003] Patent application number CN202320623125.4 is a device for preventing sonic detection tubes from being blocked. The device comprises: an inner liner tube, whose outer diameter is smaller than the inner diameter of the sonic detection tube, and which is used to be arranged in the sonic detection tube; a sinker, which is connected to the lower end of the inner liner tube, and the contour of the maximum cross section of the sinker is smaller than the inner contour of the sonic detection tube. This solution connects the sinker to the lower end of the inner liner tube, and by virtue of the gravity of the sinker, the inner liner tube can be easily inserted into the sonic detection tube, and the outer diameter of the inner liner tube is smaller than the inner diameter of the sonic detection tube, and the contour of the maximum cross section of the sinker is smaller than the inner contour of the sonic detection tube, thereby avoiding the situation where the inner liner tube and the sinker cannot be inserted into the sonic detection tube. This device cannot solve the problem that debris can easily enter the sonic detection tube and affect the test results when the sonic detection tube is being tested. Therefore, it is urgent for those skilled in the art to solve the above technical problems. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a recyclable acoustic testing tube anti-blocking protection device in view of the deficiencies of the above-mentioned prior art. The recyclable acoustic testing tube anti-blocking protection device extends a blocking piece into the acoustic testing tube through a connecting piece. The blocking piece can effectively isolate impurities from entering the acoustic testing tube and affecting the acoustic testing result. The position of the blocking piece can be adjusted through a positioning component to set a suitable blocking piece position as needed. After the test is completed, the device can be taken out through the connecting piece. The overall structure of the device is simple and the operation is convenient.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A recyclable acoustic detection pipe anti-blocking protection device is suitable for protective construction operations before pile body integrity detection after the acoustic detection pipe is installed in ultrasonic detection of bored piles or underground continuous walls, comprising a sealing piece, a connecting piece and a positioning assembly, wherein the connecting piece is welded to the bottom of the positioning assembly, the positioning assembly comprises a fixing piece and a positioning rod, two fixing pieces are provided in total and are sleeved on the positioning rod, the sealing piece is provided between the two fixing pieces, and the two fixing pieces realize the positioning of the sealing piece and drive the sealing piece to move on the positioning rod for adjustment.

[0007] Furthermore, the sealing member is composed of a flat gasket, a rubber gasket and a fixed galvanized gasket, wherein the fixed galvanized gasket is located at the bottom of the sealing member, the rubber gasket is placed on the upper part of the fixed galvanized gasket, and the flat gasket is placed on the upper part of the rubber gasket.

[0008] The flat gasket at the top layer usually has good flatness and hardness, and can evenly distribute pressure when under pressure to avoid damage caused by local overload. It is also easy to dock with other mechanical parts to provide a stable contact surface to ensure the tightness and reliability of the plugging. The rubber gasket in the middle has excellent elasticity and sealing performance. It can deform when under pressure to fill the possible tiny gaps and achieve a good sealing effect. In addition, the rubber material has certain wear resistance, aging resistance and corrosion resistance, which is very effective in preventing liquid or gas leakage in the acoustic detection tube. The fixed galvanized gasket at the bottom not only provides basic support and stability, but also the galvanizing treatment increases the corrosion resistance of the gasket and prolongs its service life. When it contacts the acoustic detection tube or other metal parts, it can effectively prevent the occurrence of electrochemical corrosion and ensure the safety of long-term use.

[0009] Furthermore, the flat gasket, the rubber gasket and the fixed galvanized gasket are all provided with positioning circular holes that match the size of the positioning rod, and the flat gasket, the rubber gasket and the fixed galvanized gasket are sleeved on the positioning rod through the positioning circular holes.

[0010] Through the cooperation of the positioning circular hole and the positioning rod, it can be ensured that the sealing piece can accurately move up and down along the positioning rod during the installation process, ensuring the accuracy and consistency of the sealing position. The three are all mounted on the positioning rod to form an overall linkage structure, so that the sealing piece will not be offset or misplaced during force or movement, thereby enhancing the sealing effect and the overall stability of the equipment. Since each gasket has a preset positioning hole, the assembly process is simplified, making the installation and disassembly of the sealing piece more convenient and quick, which is conducive to improving on-site construction efficiency.

[0011] Furthermore, the diameter of the fixed galvanized gasket is 5 mm smaller than the inner diameter of the acoustic detection tube, and the diameter of the rubber gasket is 4 mm larger than the inner diameter of the acoustic detection tube.

[0012] The diameter of the rubber gasket is slightly larger than the inner diameter of the sonic detection tube by 4mm. When the rubber gasket is compressed, it can produce a good sealing effect, effectively preventing liquid, gas or other substances from leaking from the interface of the sonic detection tube. At the same time, it also provides a certain elastic buffering effect, which helps to absorb vibration and impact. The diameter of the fixed galvanized gasket is smaller than the inner diameter of the sonic detection tube by 5mm, ensuring that it can be flexibly installed in the sonic detection tube and will not get stuck due to being too large. At the same time, when used in combination with other components (such as matching bolts), it can ensure that the gasket is tightly attached to the wall of the sonic detection tube after being subjected to the pressure of the fastener, thereby enhancing the tightness and stability of the connection. If the fixed gasket is too small, it may not provide sufficient contact area, resulting in fastening failure; if it is too large, it may cause installation difficulties or cause extrusion damage to the sonic detection tube. This design can not only ensure that there is sufficient contact between the gasket and the sonic detection tube to achieve good support, but also avoid installation problems and potential pipeline damage caused by excessive size.

[0013] Furthermore, the fixing members are two hexagonal nuts, one of which is arranged below the blocking member, and the other of which is arranged above the blocking member.

[0014] Hexagonal nuts are used as fixings, which can be tightened conveniently and powerfully with tools such as wrenches or sockets, making the fixing of the plugging piece on the positioning rod more stable and reliable and not easy to loosen and fall off. The two hexagonal nuts are placed above and below the plugging piece to achieve two-way clamping, which is convenient for precise adjustment of the plugging piece according to needs. Whether it is pushing upward or pressing downward, it can be easily controlled. The design of the upper and lower double nuts can better balance the force of the plugging piece on the positioning rod, avoiding deformation or damage of the plugging piece caused by excessive force at a single point. When the plugging piece needs to be maintained or replaced, it only needs to loosen the two nuts to quickly disassemble it. The operation is simple and efficient.

[0015] Furthermore, the connecting piece is composed of iron wires, and a total of two iron wires are welded to the bottom of the positioning rod.

[0016] The iron wire material has high strength and toughness, and can withstand large tension and pressure, ensuring that the connection between the connector and the positioning rod is firm and reliable, and will not easily break or detach due to stress. Compared with other heavy materials, the iron wire is lighter, which reduces the weight of the overall device and is more convenient for construction personnel to operate and install. The iron wire is highly flexible and can be bent into an appropriate shape as needed to meet the connection requirements of different angles and directions without affecting the movement and adjustment function of the positioning rod in the adjustment assembly. The iron wire welding process is relatively simple, the production cost is low, and it is easy to mass produce and assemble on site. The connection structure formed by the two iron wires is compact and occupies less space, which is conducive to installation and operation in a small space. If the iron wire has undergone corresponding anti-corrosion treatment, such as galvanizing, it can also effectively resist corrosion in harsh environments and extend its service life.

[0017] The utility model has the following beneficial effects:

[0018] 1. The design of the plugging piece can completely seal the port of the acoustic detection pipe to prevent the entry of mortar, gravel and other debris during the concrete pouring process, ensure the smooth flow of the interior of the acoustic detection pipe, and ensure the accuracy of subsequent ultrasonic testing. Through the positioning rod and fixing parts in the positioning assembly, the position of the plugging piece can be adjusted according to the actual situation to ensure tight sealing and facilitate the access or removal of subsequent equipment. It can be readjusted and applied to the next acoustic detection pipe, saving resources and reducing construction costs;

[0019] 2. The connecting piece is fixed to the bottom of the adjustment component by welding, which enhances the stability of the structure. At the same time, the blocking piece is positioned and moved between the two fixing pieces by the positioning rod, so that the staff can install and adjust quickly and conveniently;

[0020] 3. The device can adapt to the installation requirements of acoustic detection pipes of different depths. The connecting pieces of specified lengths can be welded on the bottom of the adjustment component to meet the requirements of acoustic detection pipes of different lengths. The position of the blocking piece can be adjusted through the adjustment component to block different positions of the same acoustic detection pipe, so that subsequent acoustic testing will not be affected.

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific preferred embodiments.

[0026] In the description of the present invention, it should be understood that the terms "left side", "right side", "upper part", "lower part", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. "First", "second", etc. do not indicate the importance of the components, and therefore cannot be understood as a limitation on the present invention. The specific dimensions used in this embodiment are only for illustrating the technical solution, and do not limit the scope of protection of the present invention.

[0027] Reference Figure 1 It can be known that a recyclable acoustic detection pipe anti-blocking protection device includes a positioning rod 31 constituting the main part of the device, two connecting parts 2 are welded at the bottom of the positioning rod 31, the positioning rod 31 is a bolt structure, and the fixing part 32 is a hexagonal bolt structure used in conjunction with the positioning rod 31. The first fixing part 321 is first installed on the specified position of the positioning rod 31, and then the blocking part 4 is installed on the positioning rod 31, and finally the second fixing part 322 is installed on the positioning rod 31. After the installation is completed, it should be ensured that the blocking part 4 is between the first fixing part 321 and the second fixing part 322, and the blocking part 4 is fixed to the positioning rod 31 by clamping the blocking part 4 with the first fixing part 321 and the second fixing part 322.

[0028] Reference Figure 2 It can be seen that the sealing piece 4 is mainly composed of a fixed galvanized sheet 43 located at the bottom of the sealing piece 4, a rubber gasket 42 located on the upper part of the fixed galvanized sheet 43, and a flat gasket 41 at the uppermost part of the sealing piece 4, wherein the diameter of the rubber gasket 42 is 4 mm larger than the diameter of the acoustic detection tube 5 to ensure that after the compression sealing device is delivered into place, the rubber gasket cannot be closely attached to the inner wall of the acoustic detection tube 5 to reduce the sealing effect, and the diameter of the fixed galvanized gasket 43 is 5 mm smaller than the inner diameter of the acoustic detection tube 5 to support the rubber gasket 42. At the same time, the flat gasket 41, the rubber gasket 42 and the fixed galvanized sheet 43 are all provided with positioning circular holes, and the diameter of the positioning circular holes is consistent with the positioning rod 31 to ensure that the sealing piece 4 can be mounted on the positioning rod 31.

[0029] Reference Figure 3It can be known that when in use, a connecting piece 2 of the required length is welded at the bottom of the positioning rod 31 as needed. The staff holds the connecting piece 2 and inserts the top end of the positioning rod 31 downward into the acoustic detection tube 5. Since the diameter of the rubber gasket 42 of the sealing piece 4 is larger than the diameter of the acoustic detection tube 5 and the rubber gasket 42 is flexible, the rubber gasket 42 can be tightly attached to the inner wall of the acoustic detection tube 5 and does not hinder the device from probing into the acoustic detection tube 5 to reach the designated position of the structural floor 1. After the top end of the positioning rod 31 reaches the designated position, water is injected into the acoustic detection tube 5 and the top of the acoustic detection tube 5 is sealed with a wooden plug. Due to the sealing of the sealing piece 4, larger impurities will not enter the interior of the acoustic detection tube 5 and will not affect the test of the acoustic detection tube 5. After the acoustic test is completed, it is only necessary to remove the wooden plug, lift the connecting piece 2 and take the entire device out of the acoustic detection tube 5.
