[0002] Concrete cut-off wall is the most effective anti-seepage treatment method for deep overburden foundation. Ultra-deep overburden foundation has engineering geological problems such as differential settlement, dam foundation leakage, seepage deformation, earthquake liquefaction, etc. Under the unfavorable geological conditions of ultra-deep overburden, problems are prone to occur in the trench section during construction. However, since the construction of cut-off wall is an underground hidden project, it is constrained by detection methods and detection technologies. The detection of deep cut-off wall is difficult, and the detection accuracy is easily affected by the sampling rate. The detection workload is large, time-consuming and labor-intensive.

[0006] A sliding block, slidably connected to the annular guide rail, the sliding block is configured to be driven by an external force to move on the annular guide rail, and a detection member for detecting the slot body is fixedly connected to the sliding block;

[0007] When the milling frame enters the slot body, the detection member moves synchronously with the sliding block along the circumference of the milling frame to detect at least a portion of the slot body.

[0008] Furthermore, the detection component is an ultrasonic infrared detector, and the construction detection device also includes:

[0009] A multi-axis anti-shake gimbal is fixedly connected to the sliding block at one end, and the other end of the multi-axis anti-shake gimbal is provided with a stabilizing arm extending toward the side end of the milling frame, and the detection member is connected to the stabilizing arm to detect the side wall portion of the trough body.

[0010] Furthermore, the stabilizing arm is connected to a universal joint, the anti-shake gimbal is provided with a driving motor for driving the universal joint to tilt and deflect, and the detection element is connected to the universal joint to tilt and rotate synchronously with the universal joint;

[0011] Wherein, taking the horizontal plane as the reference plane, the inclination angle range of the detection member is ±35°-±50°.

[0012] Furthermore, a magnetic attraction component is provided on one side of the annular guide rail facing the milling frame, and the annular guide rail is adsorbed on the milling frame through the magnetic attraction component.

[0013] Furthermore, a plurality of groups of elastic members are connected at intervals on one side of the annular guide rail toward the milling frame, and one end of the plurality of groups of elastic members facing away from the annular guide rail is fixedly connected to the magnetic member. When the magnetic member is adsorbed on the milling frame, a gap exists between the annular guide rail and the milling frame bracket.

[0014] Furthermore, the annular guide rail is a rectangular guide rail with rounded corners on all sides, the sliding block is provided with a roller and a stepping motor for driving the roller to rotate, and the sliding block is constrained on the annular guide rail and abuts against the annular guide rail through the roller.

[0015] Furthermore, it also includes a protective shell, the detection element is covered in the protective shell, and the protective shell has an opening to avoid the detection head of the detection element.

[0018] Based on the same inventive concept, the present application also provides a construction method of an anti-seepage wall, which is applicable to any of the construction detection devices described above, and the method comprises:

[0019] spraying a dispersant material on the annular guide rail and the sliding block;

[0020] After the guide wall is constructed to form the groove, the annular guide rail is fixed to the milling frame of the groove forming machine;

[0033] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0034] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present invention should be understood by people with ordinary skills in the field to which the present disclosure belongs.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0035] In actual projects, the technology for monitoring the anti-seepage wall is carried out after the trenching construction, and the construction quality is tested by non-destructive methods such as excavation core inspection or radar monitoring, ultrasonic method, etc. For the anti-seepage of the dam foundation with ultra-thick overburden, it is necessary to use ultra-deep anti-seepage walls for anti-seepage treatment. As the depth of the anti-seepage wall increases, the problems encountered by the anti-seepage wall during the trenching construction will become more prominent, such as leakage of the trench section, stability problems, local collapse, etc., and the trenching quality affects the quality of the subsequent dam and the seepage safety. Therefore, the trenching quality should be given special attention. During the trenching process, the trench section should be monitored in real time so that measures can be taken in time to remedy the existing problems.

[0036] However, the current real-time detection method during the grooving process is generally to construct for a period of time - stop work - detect the quality of the grooving body 300 - continue construction, or to inspect the completed grooving body 300 after completing the construction of a section of the grooving body 300. The first detection method mentioned above requires stopping the grooving machine, resulting in a waste of time and extended construction period. The second detection method finds quality problems during detection and requires the completed grooving body 300 to be reworked, wasting time and labor costs.

[0037] Based on the above related technical description, one or more embodiments of the present application provide a construction detection device for an anti-seepage wall, which is described below with reference to the accompanying drawings.

[0038] like Figure 1 As shown, the present application provides a construction detection device for an anti-seepage wall, which is used to be loaded on a slotting machine. The slotting machine includes a milling frame 100, and the milling frame 100 is used to extend into the slot body 300 to perform slot milling work.

[0039] The construction detection device described in the present application includes an annular guide rail 200 and a sliding block 201, wherein the annular guide rail 200 is fixed on the milling frame 100 in the circumferential direction of the milling frame 100; the sliding block 201 is slidably connected to the annular guide rail 200, and the sliding block 201 is configured to be driven by an external force to move on the annular guide rail 200, and a detection member 205 for detecting the trough body 300 is fixedly connected to the sliding block 201. When the milling frame 100 enters the trough body 300, the detection member 205 moves synchronously with the sliding block 201 along the circumferential direction of the milling frame 100 to detect at least part of the trough body 300.

[0040] From the above description, it can be seen that the construction detection device described in the present application is achieved by installing an annular guide rail 200 on the milling frame 100, and a sliding block 201 is slidably connected to the annular guide rail 200. Since the sliding block 201 is provided with a detection member 205, the detection member 205 moves synchronously with the sliding block 201 along the circumference of the milling frame 100 to detect at least a portion of the trough body 300. When the milling frame 100 is extended into the trough body 300 for milling, the detection member 205 can move around the milling frame 100 while performing real-time quality detection on the peripheral side walls of the trough body 300, so that the anti-seepage wall can also be inspected during the construction process, thereby realizing quality control of the trough body 300 during the construction process, which is conducive to timely protection and repair measures for the trough body 300 during construction, thereby ensuring the quality of the trough and seepage safety.

[0041] It should be noted that in the embodiment of the present application, the slotting machine may adopt mechanical equipment used in the slotting construction project in the relevant technology. For example, the slotting machine adopts the BC36 hydraulic double-wheel milling slotting machine in the relevant technology. The slotting machine includes lifting equipment, slot washing machine, mud preparation and screening system and other parts. Among them, the milling frame 100 is a steel frame with a hydraulic and electrical control system. The lower end of the milling frame 100 is equipped with a horizontally arranged hydraulic motor, and the hydraulic motor is used to drive two milling wheels 101 equipped with milling teeth respectively. During the process of the slotting machine milling the slot body 300, the two milling wheels 101 rotate at a low speed in opposite directions, and their milling teeth mill and crush the surrounding rock of the formation. The middle hydraulic motor drives the mud pump, and the mixture of drilled rock debris and mud is discharged to the ground mud station through the sand suction port 102 in the middle of the milling wheel 101 for centralized sand removal treatment, and then the purified mud is returned to the slot section, and the cycle is repeated until the final hole is slotted. Figure 1 It can also be seen that the milling frame 100 of the slotting machine will penetrate into the slot body 300 to facilitate the milling wheel 101 to perform the slot milling work.

[0042] In the above description, the annular guide rail 200 is arranged on the part of the milling frame 100 close to the milling wheel 101. Here, in order to avoid the annular guide rail 200 from contacting the groove wall part of the groove body 300 during the groove milling process and affecting the detection work, the protruding thickness of the annular guide rail 200 on the milling frame 100 should be reduced as much as possible. For example, the milling frame 100 has a circumferentially recessed annular groove, and the annular guide rail 200 is installed in the annular groove. The maximum width of the entire construction detection device is less than or equal to the milling groove width of the milling wheel 101. This setting can also prevent the detection member 205 from being blocked by mud and damaging the detection member 205.

[0043] like Figure 2 As shown, in some embodiments, since the milling frame 100 is mostly a rectangular frame structure, the annular guide rail 200 is set as a rectangular guide rail with rounded corners on all sides, the sliding block 201 is provided with a roller and a stepper motor for driving the roller to rotate, the sliding block 201 is constrained on the annular guide rail 200 and abuts against the annular guide rail 200 through the roller, and the rounded corners of the annular guide rail 200 can be used to weaken the rotation interference of the sliding block 201 in the corner area, so as to facilitate the sliding block 201 to perform corner movements more smoothly. In addition, the stepper motor can adopt a servo stepper motor in the relevant technology, and the two rollers on the sliding block 201 are connected by a transmission rod. The stepper motor drives the transmission rod to rotate, so that the roller rolls on the annular guide rail 200, thereby realizing the displacement of the sliding block 201 on the annular guide rail 200.

[0044] In the above embodiment, the rollers can be arranged into multiple groups at intervals, each group of rollers consists of two rollers driven by a transmission rod, and the multiple groups of rollers are driven together by a stepper motor. Arranging multiple groups of rollers can enhance the displacement stability of the sliding block 201 on the annular guide rail 200.

[0045] It should be noted that, in some embodiments, the annular guide rail 200 is a frame-skeleton type guide rail with a hollow middle portion. The hollow middle portion design can not only reduce the overall weight of the detection device and facilitate disassembly and assembly, but also, when mud is splashed onto the annular guide rail 200 during the grooving construction process, it can also fall through the hollow portion, thereby preventing the mud from blocking the sliding path of the sliding block 201 and ensuring the normal displacement of the sliding block 201.

[0046] In some embodiments, a dispersant material is also coated on the sliding path of the annular guide rail 200 and the sliding block 201. The dispersant material can be a mineral mud dispersant in the related art, and the dispersant is used to break the adsorption and aggregation forces between the mineral mud particles, thereby preventing the mud agglomerates adhering to the annular guide rail 200 from blocking the sliding path. Of course, as an alternative embodiment, the annular guide rail 200 and the sliding block 201 can also be soaked in the dispersant in advance to maintain the dispersant's mud dispersing properties.

[0047] like Figure 2 As shown, in some embodiments, a magnetic member 207 is provided on one side of the annular guide rail 200 facing the milling frame 100, and the annular guide rail 200 is adsorbed on the milling frame 100 by the magnetic member 207. Here, the magnetic member 207 is a magnet. The annular guide rail 200 is adsorbed on the milling frame 100 by the magnetic member 207, which can facilitate the disassembly and fixation of the annular guide rail 200, thereby facilitating the staff to detect the trough body 300.

[0048] Furthermore, a plurality of groups of elastic members 206 are connected at intervals on one side of the annular guide rail 200 facing the milling frame 100, and one end of the plurality of groups of elastic members 206 facing away from the annular guide rail 200 is fixedly connected to the magnetic member 207, and when the magnetic member 207 is adsorbed on the milling frame 100, there is a gap between the annular guide rail 200 and the support of the milling frame 100. Here, based on the annular guide rail 200 being a rectangular frame-type guide rail, exemplarily, more than two groups of elastic members 206 are provided on each side of the annular guide rail 200, and the elastic members 206 are high-strength springs, and one end of the elastic members 206 facing the milling frame 100 is fixedly connected to the magnetic member 207, and adsorbed on the milling frame 100 through the magnetic member 207.

[0049] Since the four sides of the annular guide rail 200 are connected to the milling frame 100 through the elastic member 206, when the milling frame 100 vibrates with the milling groove, the vibration impact in different directions can be absorbed and buffered by the four sides of the annular guide rail 200, thereby improving the overall shockproof performance of the construction detection device and ensuring the normal detection of the detection member 205. In addition, when the size of the milling frame 100 is different, since the magnetic member 207 is elastically connected to the annular guide rail 200, the position of the magnetic member 207 can flexibly adapt to the size change of the milling frame 100, so it can be widely used in slotting machine equipment of different product types.

[0050] like Figure 3 As shown, in some embodiments, the detection element 205 is an ultrasonic infrared detector. The ultrasonic function of the detection element 205 can be used to detect the integrity and continuity of the tank body 300. When the tank body 300 leaks, there is a temperature difference between the temperature of the leaking liquid and the main body temperature of the tank body 300. The infrared function of the detection element 205 can be used to detect whether there is leakage or abnormal temperature points in the tank body 300.

[0051] In the above embodiment, the construction detection device also includes a multi-axis anti-shake gimbal 202, one end of which is fixedly connected to the sliding block 201, and the other end of the multi-axis anti-shake gimbal 202 has a stabilizing arm 203 extending toward the side end of the milling frame 100, and the detection component 205 is connected to the stabilizing arm 203 to detect the side wall portion of the trough body 300. Here, the multi-axis anti-shake gimbal 202 can adopt an anti-shake gimbal device in the related technology. For example, the multi-axis anti-shake gimbal 202 is a three-axis anti-shake gimbal, which includes an inertial measurement unit, a motor and a control chip. The inertial measurement unit is provided with an accelerometer, a gyroscope, a magnetometer and other orientation detection components. The inertial measurement unit transmits the motion data measured by the accelerometer, the gyroscope, the magnetometer and other orientation detection components to the control chip. The control chip corrects the orientation of the stable support arm 203 by controlling the motor to keep the vibration of the stable support arm 203 within the allowable range. The anti-shake gimbal can improve the stability detection of the detection element 205. It should be noted that for different multi-axis anti-shake gimbals 202, the components, correction methods and algorithms included will also be different, and can be set with reference to the basic principles and steps.

[0052] like Figure 4 As shown, in some embodiments, a universal joint 204 is connected to the stabilizing arm 203 , a driving motor for driving the universal joint 204 to tilt and shift is provided on the anti-shake gimbal, and the detection member 205 is connected to the universal joint 204 to tilt and rotate synchronously with the universal joint 204 .

[0053] Here, the universal joint 204 can adopt a mature mechanical linkage component for transmitting torque and angle in the relevant technology. The drive motor is fixed on the stabilizing arm 203. The output end of the drive motor is connected with a transmission shaft, which is matched and connected with the inner ball cage of the universal joint 204. The outer ball cage is connected to the detection member 205. When the drive motor rotates, the inner ball cage rotates accordingly, and transmits power to the outer ball cage through the rolling action of the ball, thereby driving the detection member 205 to rotate at a preset angle. The above-mentioned setting can make the universal joint 204 rotate smoothly at different angles and positions, and can effectively transmit power. Therefore, the drive motor can be driven to rotate actively through the universal joint 204, so that the entire system can be more flexibly adapted to different working conditions and angle requirements.

[0054] As an alternative implementation, the universal joint 204 may also adopt a rotary joint to achieve angle rotation adjustment, and the rotary joint is driven by a driving motor to perform a rotational motion.

[0055] In the above embodiment, the detection head of the detection member 205 is facing the side wall direction of the slot body 300. When the driving motor drives the universal joint 204 to rotate and causes the detection member 205 to rotate, the detection head is driven to swing up and down in an arc. Here, the ultrasonic infrared detector can use a detection head for planar detection, that is, a plurality of ultrasonic sensors or infrared sensors are used on the detection head. When the detection head is driven to swing downward, the detection range of the detection head can cover the bottom part of the slot body 300, thereby detecting the bottom part of the slot body 300. When the detection head is driven to swing upward, the detection range of the detection head covers the slot wall part of the slot body 300, thereby detecting the slot wall part of the slot body 300.

[0056] Exemplarily, with the horizontal plane as the reference plane, the inclination angle range of the detection member 205 is ±35°-±50°, and further, the inclination angle of the detection member 205 is ±35°, ±45° or ±50°. That is, when the inclination angle of the detection member 205 is +35°, the detection member 205 detects the groove wall portion of the groove body 300, and when the inclination angle of the detection member 205 is -35°, the detection member 205 detects the groove bottom portion of the groove body 300.

[0057] It should be noted that since the detection member 205 is driven by the sliding block 201 to rotate circumferentially, during the circumferential rotation, it is necessary for the detection member 205 to detect the bottom portion of the groove of the groove body 300 and cover the entire groove bottom, so as to ensure the quality inspection process of the entire groove bottom. Therefore, the detection member 205 can be adjusted by adjusting the inclination angle of the detection member 205, the position of the annular guide rail 200 on the milling frame 100, or changing the detection range of the detection member 205 to ensure that the detection member 205 can completely detect the bottom portion of the groove of the groove body 300 during the axial rotation.

[0058] like Figure 3 As shown, in some embodiments, a protective shell 208 is further included, and the detection member 205 is covered in the protective shell 208, and the protective shell 208 has an opening for avoiding the detection head of the detection member 205. Here, the protective shell 208 is made of metal material, and the shell can be fixed on the stable support arm 203 by welding or bolts. The opening of the protective shell 208 is used to avoid the detection head. During the detection process of the detection member 205, as the trenching machine advances, the pressure on the equipment and devices mounted on the milling frame 100 increases. By setting up the protective shell 208, on the one hand, it can prevent mud splashing and damaging the equipment, and on the other hand, it can also protect the monitoring equipment from pressure.

[0059] In some embodiments, the construction detection device also includes a data transmission module, which is connected to the detection member 205. The data transmission module is configured to receive the detection data of the detection member 205 and transmit the detection data to an external device. Here, the data transmission module and the detection member 205 can transmit data via a data line or wirelessly. For example, the monitoring results can be transmitted to the upper terminal server in real time by the data transmission module. The upper terminal server performs online real-time monitoring. If an abnormality is found, the leakage site can be processed immediately to achieve the purpose of trench quality control. Here, the data transmission module uses a summary switch.

[0060] Based on the same inventive concept, the present application also provides a construction method of an anti-seepage wall, which is applicable to the construction detection device described in any one of the above embodiments, and the method comprises:

[0061] Spraying dispersant material on the annular guide rail 200 and the sliding block 201;

[0062] After the guide wall is constructed to form the groove, the annular guide rail 200 is fixed to the milling frame 100 of the groove forming machine;

[0063] When the milling frame 100 of the slotting machine starts to drill and descend, the sliding block 201 is driven to move uniformly along the annular guide rail 200, and the detection member 205 is started to detect the slot body 300; wherein the detection speed of the detection member 205 is positively correlated with the excavation speed of the slotting machine; and / or,

[0064] When the milling frame 100 of the slotting machine finishes drilling and ascending, the sliding block 201 is driven to move uniformly along the annular guide rail 200, and the detection member 205 is started to detect the slot body 300; wherein, the detection speed of the detection member 205 is positively correlated with the ascending speed of the slotting machine.

[0065] In the above steps, since the anti-seepage wall groove is filled with mud during the construction process, the track may be blocked by mud during the monitoring operation. Therefore, before lowering the platform, a dispersant material is sprayed on the annular guide rail 200 and the sliding block 201. The dispersant is a substance that disperses a substance in a medium such as water to form a colloidal solution to prevent flocculation or agglomeration, thereby ensuring the normal sliding action of the sliding block 201 on the annular guide rail 200. As an alternative embodiment, the annular guide rail 200 and the sliding block 201 can also be soaked in the dispersant in advance.

[0066] An exemplary process of the construction method described in this application is as follows:

[0067] (1) The annular guide rail 200 and the sliding block 201 are soaked in a dispersant in advance.

[0068] (2) After the guide wall is grooved by the hydraulic grab groove forming mechanism, the annular guide rail 200 is adsorbed onto the milling frame 100 of the rolling milling groove forming machine, and the multi-axis anti-shake gimbal 202 and the detection member 205 are assembled on the sliding block 201;

[0069] (3) After the milling frame 100 is lowered, the servo motor is started to drive the sliding block 201 to rotate at a uniform speed. At the same time, the detection member 205 is started to perform thermal imaging surround detection on the side wall of the groove section. The detection speed is coordinated with the excavation speed of the roller milling slotting machine;

[0070] (4) After excavation to the target depth, the driving motor drives the universal joint 204 to drive the detection member 205 to tilt downward, and the tilted detection member 205 performs cyclic detection on the bottom of the groove;

[0071] (5) After the surrounding detection is completed, the driving motor drives the universal joint 204 to drive the detection member 205 to restore the horizontal position. When the drilling is completed and the milling cutter is lifted, the groove wall portion of the groove body 300 is repeatedly monitored for the second time.

[0072] Those skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative and is not intended to imply that the scope of the present disclosure (including the claims) is limited to these examples. Within the scope of the present invention, the above embodiments or technical features in different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
