Description

Technical Field

[0001] The utility model belongs to the technical field of pile detection, and in particular relates to reinforced concrete pile detection equipment. Background Art

[0002] Reinforced concrete piles are widely used in complex natural environments to support major structures in fields such as transportation, water conservancy, and port and shipping. Potential corrosion not only weakens the mechanical properties of the steel, resulting in a decrease in the strength of the pile foundation structure, but also potentially affects the stability and safety of the entire building, posing a potential safety hazard to the normal operation of surrounding facilities. Reinforced concrete piles are particularly vulnerable to electrochemical corrosion because they are located above ground and are subject to external forces, wind, rain, sun, and acidic air. This often exposes the steel bars, making them susceptible to electrochemical corrosion. Regular electrochemical testing of these piles is essential.

[0003] However, the above-ground portion of reinforced concrete piles still has a certain height, and electrochemical testing equipment often relies on manual deployment. Testing the entire height of the above-ground portion of reinforced concrete piles, which is inaccessible to humans, requires the use of climbing equipment. Each change in location requires readjusting or moving the climbing equipment, which is labor-intensive and time-consuming, and results in low testing efficiency. Therefore, a device is needed to perform electrochemical testing of the entire height of the above-ground portion without the use of climbing equipment. Summary of the Invention

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] The basic idea of ​​this utility model is to surround a stainless steel stirrup at a distance outside the reinforced concrete pile.

[0034] A mobile module and a detection device are connected to the stainless steel stirrups. After the mobile module is controlled to move the stainless steel stirrups and the detection device to the target position on the reinforced concrete pile, the detection device is controlled to perform corrosion electrochemical information detection on the reinforced concrete pile. The detection results are transmitted to the electrochemical workstation via wired or wireless means for analysis. Example

[0035] See Figure 1 、 2 In this embodiment, the stainless steel stirrups are square stainless steel stirrups, which are suitable for square reinforced concrete piles. The stainless steel stirrups include two single-piece stainless steel stirrups 100, which are detachably connected. Each single-piece stainless steel stirrup 100 has the same structure and is in the shape of [, with a blind hole 101 at one end and a docking rod 102 that matches the blind hole 101 at the other end. A radial first through hole 103 is provided on the single-piece stainless steel stirrup 100 at the position where the blind hole 101 is provided, and a radial second through hole 104 is provided on the docking rod 102. After the docking rod 102 is inserted into the blind hole 101, the first through hole 103 and the second through hole 104 are connected. The first through hole 103 and the second through hole 104 can be pin holes, or they can be threaded holes.

[0036] When assembling stainless steel stirrups 100 from two single-piece stainless steel stirrups, the butt rods 102 of the two single-piece stainless steel stirrups 100 are inserted into the blind holes 101 of the other single-piece stainless steel stirrups 100. If the first through hole 103 and the second through hole 104 are threaded holes, they are fastened by screwing with bolts; if the first through hole 103 and the second through hole 104 are pin holes, they are fastened by plugging with pins.

[0037] The electrochemical workstation has three types of input ports: working electrode, reference electrode, and counter electrode. The working electrode is electrically connected to the steel bars exposed outside the reinforced concrete, and the reference electrode is electrically connected to the reference electrode 307 on the reference electrode module 300.

[0038] A spiral connector 110 electrically connected to one of the single stainless steel stirrups 100 is embedded in the stirrup. The spiral connector 110 is electrically connected to a port of a suitable counter electrode in an electrochemical workstation via a wire. When the stainless steel stirrup is energized, the stainless steel stirrup 100 becomes a ring-shaped counter electrode for the corresponding measurement section of the reinforced concrete pile. The spiral connector 110 has good electrical conductivity, reliability, and safety, ensuring the stability of the wire connection.

[0039] The reference electrode 307 on the reference electrode module 300 is electrically connected to a port of the electrochemical workstation adapted for a reference electrode through a wire.

[0040] Stainless steel stirrups are made into different sizes and specifications to adapt to reinforced concrete piles of different sizes and specifications.

[0041] The area enclosed by the stainless steel stirrups is larger than the cross-sectional area of ​​the reinforced concrete pile. When the stainless steel stirrups are sleeved on the reinforced concrete pile, the inner sides of the four sides are at a certain distance from the side surfaces of the reinforced concrete pile, forming a spaced-apart surrounding the reinforced concrete pile.

[0042] like Figure 3 As shown, the moving module 200 includes a sealing box 201 , a first motor 202 , a rotating shaft 203 , a roller 204 , a rubber sealing ring 205 and a first driving module 206 .

[0043] The first motor 202 is installed inside the sealed box 201, and the first driving module 206 is equipped with a working power supply battery, a driving circuit and a wireless signal communication module. Its driving circuit is electrically connected to the first motor 202, and the roller 204 is connected to the first motor 202 through the rotating shaft 203 and sealed by the rubber sealing ring 205.

[0044] After receiving the control signal, the wireless signal communication module on the first driving module 206 activates the driving circuit to make the first motor 202 rotate forward or reverse. The first motor 202 drives the roller 204 to rotate forward or reverse through the rotating shaft 203 .

[0045] In order to ensure the balance and stability of the lifting of the reinforced concrete pile detection equipment, at least two sets of mobile modules 200 are configured.

[0046] See Figure 4-6 The reference electrode module 300 includes an outer cylinder 301 , an inner cylinder 302 , a second motor 303 , a lead screw 304 , a second driving module 305 , a spring 306 , a reference electrode 307 and a pressure sensor 308 .

[0047] In this embodiment, a set of reference electrode modules 300 is provided.

[0048] The outer cylinder 301 and the inner cylinder 302 are both cylindrical structures with an opening at one axial end and a bottom wall at the other end. The outer wall of the inner cylinder 302 is slidably connected to the inner wall of the outer cylinder 301; the second motor 303 is fixedly connected to the inner bottom wall of the outer cylinder 301, and the output shaft of the second motor 303 is fixedly connected to the screw 304. A threaded through hole is provided on the bottom wall of the inner cylinder 302, and the screw 304 is threadedly connected to the threaded through hole of the inner cylinder 302; the second driving module 305 is fixedly connected to the outer peripheral wall of the second motor 303, and the second driving module 305 is equipped with a battery for working power supply, a driving circuit and a wireless signal communication module, and its driving circuit is electrically connected to the second motor 303. A through hole is provided on the side wall of the outer cylinder 301 at a position corresponding to the second driving module 305, which is conducive to the communication between the wireless signal communication module and the electrochemical workstation and the reception of remote control signals. The reference electrode 307 is electrically connected to the port of the electrochemical workstation adapted to the reference electrode. The connecting wire is also passed through the through hole (not shown in the figure); the reference electrode 307 is provided with a protective tube, and an elastic rubber sheet is padded between the reference electrode 307 and the protective tube. The protective tube is fixedly connected to the inner wall of the inner cylinder 302, and the reference electrode 307 and the front end of the protective tube extend outside the inner cylinder 302. The reference electrode 307 and the rear end of the protective tube are connected to the spring 306 and the pressure sensor 308. The reference electrode 307 is electrically connected to the wireless signal communication module of the second drive module 305, and the pressure sensor 308 is electrically connected to the drive circuit of the second drive module 305. After receiving the control signal, the wireless signal communication module on the second drive module 305 activates the drive circuit to cause the second motor 303 to rotate forward or reverse. The second motor 303 drives the screw 304 to rotate forward or reverse via the output shaft. The screw 304 drives the inner cylinder 302 to slide back and forth within the outer cylinder 301, thereby extending or retracting the reference electrode 307.

[0049] See Figure 7-9 The mobile module 200 and the reference electrode module 300 are connected to the stainless steel stirrups via a clamp connector 400. The clamp connector 400 includes a clamp-type device 401, a screw 402, and a nut 403. The clamp-type device 401 is fixedly connected to the outer bottom wall of the sealing box 201 of the mobile module 200 and the outer cylinder 301 of the reference electrode module 300, respectively, and is connected to the stainless steel stirrups via the screw 402 and the nut 403. Example

[0050] The difference between this embodiment and embodiment 1 is that the stainless steel stirrups are circular.

[0051] See Figure 10 and 11, circular stainless steel stirrups are suitable for circular reinforced concrete piles. The stainless steel stirrups include two semicircular stainless steel stirrups 100. Each end of the two semicircular stainless steel stirrups 100 is hinged by a hinge 105. The other end of one semicircular stainless steel stirrup 100 is provided with a blind hole 101, and the other end of the other semicircular stainless steel stirrup 100 is provided with a docking rod 102 that matches the blind hole 101. A radial first through hole 103 is provided on the single-piece stainless steel stirrup 100 at the position where the blind hole 101 is provided, and a radial second through hole 104 is provided on the docking rod 102. After the docking rod 102 is inserted into the blind hole 101, the first through hole 103 and the second through hole 104 are connected. The first through hole 103 and the second through hole 104 can be pin holes, and the first through hole 103 and the second through hole 104 can also be threaded holes.

[0052] The mobile module 200 and the reference electrode module 300 are also connected to the circular stainless steel stirrups via the hoop connector 400. The assembly arrangement is the same as that of Example 1 and will not be described in detail.

[0053] When the reinforced concrete pile detection device of the present invention is used, it is also equipped with a remote control, which is wirelessly connected to the wireless signal communication module of the first drive module 206 and the wireless signal communication module of the second drive module 305. The remote control is provided with "up", "down", "stop 1", "extend", "retract", and "stop 2" function buttons. After pressing the "up" button, the first motor 202 rotates forward, and the first motor 202 drives the roller 204 to rotate forward through the rotating shaft 203. The roller 204 is in contact with the side of the reinforced concrete pile, and the friction between the roller 204 and the side of the reinforced concrete pile drives the stainless steel stirrup and its reference electrode module. 300 climbs upward along the side of the reinforced concrete pile; after pressing the "down" button, the first motor 202 reverses, and the first motor 202 drives the roller 204 to reverse through the rotating shaft 203, and the roller 204 is in contact with the side of the reinforced concrete pile. With the help of the friction between the roller 204 and the side of the reinforced concrete pile, the stainless steel stirrups and its reference electrode module 300 are driven to descend along the side of the reinforced concrete pile; after pressing the "stop 1" button, the first motor 202 stops rotating, and the roller 204 is in contact with the side of the reinforced concrete pile. With the help of the friction between the roller 204 and the side of the reinforced concrete pile, the reinforced concrete pile detection equipment is stationed on the side of the reinforced concrete pile.

[0054] Initially, the inner cylinder 302 of the reference electrode module 300 is retracted to its starting position in the outer cylinder 301. After pressing the "extend" key, the second motor 303 rotates forward, and the second motor 303 drives the lead screw 304 to rotate forward through the output shaft. The lead screw 304 drives the inner cylinder 302 to slide forward in the outer cylinder 301, so that the reference electrode 307 is extended and connected with the side of the reinforced concrete pile. The reference electrode 307 transmits pressure to the pressure sensor 308 through the spring 306. When the pressure reaches the set pressure threshold, the driving circuit of the second driving module 305 stops driving the second motor 303 to rotate; press the "retract" key. After pressing the "Stop 2" key, the second motor 303 reverses, and the second motor 303 drives the lead screw 304 to reverse through the output shaft, and the lead screw 304 drives the inner cylinder 302 to slide backward in the outer cylinder 301, so that the reference electrode 307 is retracted, and the reference electrode 307 is out of contact with the side of the reinforced concrete pile. After pressing the "Stop 2" key, the second motor 303 stops rotating. It is not necessary to wait until the inner cylinder 302 is retracted to the starting position in the outer cylinder 301 to press the "Stop 2" key. As long as the inner cylinder 302 is retracted to the point where the reference electrode 307 does not touch the side of the reinforced concrete pile during the ascent or descent process, the "Stop 2" key can be pressed.

[0055] The pressure threshold is set according to the parameters of the reinforced concrete piles actually tested. In actual use, in order to ensure the density of contact, an excessive value method is adopted, which is appropriately larger rather than smaller. It is generally set at 130-200N.

[0056] The utility model is suitable for detecting electrochemical information of reinforced concrete pile foundations at different heights in a complex environment. The method of using the utility model comprises the following steps: first, connecting the exposed steel bars of the reinforced concrete pile to the port of the working electrode in the electrochemical workstation with a wire; then, selecting stainless steel stirrups of different specifications and sizes according to the size of the reinforced concrete pile to be detected, so that they are adapted to the reinforced concrete pile; the third step is assembly: surrounding several single-piece stainless steel stirrups around the reinforced concrete pile, combining and fastening them into stainless steel stirrups, and then installing the mobile module and the reference electrode module on the stainless steel stirrups, so that the rollers of the mobile module are in close contact with the side of the reinforced concrete pile; the fourth step is connecting the reference electrode and the counter electrode, connecting the stainless steel stirrups and the counter electrode of the electrochemical workstation with a wire, and connecting the detection device with a wire. The reference electrode on the device and the reference electrode on the electrochemical workstation are compared. Step 5: Move the device to the target location for testing: Press the "Up" or "Down" button on the remote control to move the device to the target location. Press the "Extend" button on the remote control to bring the reference electrode into close contact with the reinforced concrete pile. When the contact pressure detected by the pressure sensor reaches the preset pressure threshold, the second motor stops, and the reference electrode firmly contacts the side of the reinforced concrete pile. Step 6: Test: The reference electrode, the concrete reinforcement (working electrode), and the stainless steel stirrups (counter electrode) form a complete three-electrode system. The electrochemical workstation collects real-time electrochemical information about the concrete pile foundation at its current height. Step 5: Move to the next target location for testing: Press the "Retract" button and the "Stop 2" button on the remote control, then press the "Up" or "Down" button to move the device to the next target location. Repeat steps 5 and 6 to complete electrochemical testing at different pile foundation heights. The control system and electrochemical workstation record and save electrochemical data at different heights. Analyze these data, evaluate the overall corrosion condition of the pile foundation, and predict future corrosion trends to provide a basis for project maintenance; Step 7, End: Press the "Down" button on the remote control to lower the equipment to the ground, disassemble and store it for later use.

[0057] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
