Description

Technical Field

[0001] The present invention relates to the technical field of canal repair, and particularly to a leveling equipment and method for underwater repair operation of concrete lining panels of water network canals. Background Art

[0002] As important water conservancy infrastructure, water network canals are widely used in fields such as farmland irrigation, urban water supply, flood control and drainage. In order to adapt to different geological and hydrological conditions, the cross-section of the canal mainly adopts a trapezoidal cross-section, which can effectively prevent slope collapse, ensure the stability of the canal, and facilitate construction and maintenance at the same time. The concrete lining panel of the water network canal, as the key anti-seepage layer of the water conveyance structure, has been damaged due to long-term influence of factors such as hydraulic scouring, temperature stress and foundation deformation. After investigation and statistics, the damage of the concrete lining panel of the backbone water network mainly focuses on panel cracks, slope deformation, overall panel shedding, etc. After the lining panel is damaged, it will not only increase the leakage risk, but also cause secondary scouring due to water flow turbulence, resulting in accelerated structural deterioration, seriously threatening the operation safety and service life of the canal, and must be repaired in time.

[0003] When repairing the damaged lining panel, it is often necessary to extract the damaged lining panel and replace it with a new one. When extracting the lining panel, affected by the acting force, the underlying geomembrane or insulation layer will deform to a certain extent following the lifting of the lining panel, making the base surface uneven, thus affecting the installation of the new lining panel. It often requires manual underwater assistance to flatten or fill, which not only has a high operation risk but also reduces efficiency. Summary of the Invention

Detailed implementation manners

[0042] The technical solutions in the present invention will be further described below in conjunction with the drawings and embodiments.

[0043] As Figure 1 shown, an embodiment of the present invention provides a leveling equipment for underwater repair operation of concrete lining panels of water - network channels, including:

[0044] A bearing frame 1, having a storage cavity 101 for storing sandbags, and a feeding opening 102 for discharging sandbags is opened at the bottom of the storage cavity 101;

[0045] A fixing frame 2, arranged on one side of the bearing frame 1 away from the feeding opening 102, and provided with a leveling unit for leveling the base surface of the channel;

[0046] A conveying unit, arranged on the bearing frame 1, for conveying the sandbags stored in the storage cavity 101 to the feeding opening 102;

[0047] And a detection unit, for detecting the convex or concave conditions of the base surface, and the detection unit is installed on the side or bottom surface of the bearing frame 1.

[0048] In the embodiment of the present invention, the bearing frame 1 is composed of a rectangular frame and rectangular panels on each side, so that the formed bearing frame 1 has a storage cavity 101 capable of storing sandbags. Before underwater leveling, sandbags can be pre - stored in the storage cavity 101, or can be stored subsequently according to the detection of the base surface. During the movement of the entire leveling equipment, in order to ensure its stability, it can be carried in the form of a truss. The truss is laid along the depth direction of the channel, and the leveling equipment is installed on the truss. The installation methods include but are not limited to the sliding method, and the entire equipment is driven to move on the truss by hoisting or traction.

[0049] After the carrying frame 1 moves to the specified repair area, according to the repair needs, when the detection unit detects that the base surface has some convex surfaces, the movement of the carrying frame 1 is controlled, so as to drive the leveling unit to move on the base surface, and then flatten the convex surfaces, and ensure the flatness of the base surface, which is convenient for the subsequent installation of new plates. In the installation of the detection unit, it is preferably installed at the bottom of the carrying frame 1 and close to the feeding port 102. The detection unit uses various existing detection devices, and is connected to an external controller to facilitate control and understanding of the canal surface conditions.

[0050] Specifically, as Figures 2 to 4 shown, the leveling unit includes a rolling roller 4 and / or an excavating roller 3. The rolling roller 4 and / or the excavating roller 3 are connected to the fixed frame 2 through a driving mechanism. The driving mechanism includes a cylinder 7 and a transmission 401, 301. The cylinder 7 is used to adjust the working height of the rolling roller 4 and / or the excavating roller 3, and the transmission 401, 301 is used to drive the rolling roller 4 and / or the excavating roller 3 to rotate.

[0051] The cylinder 7 is installed on the fixed frame 2. Both the rolling roller 4 and the excavating roller 3 are slidably installed on the fixed frame 2 through a frame. For example, taking four cylinders 7 as an example, the cylinders 7 in pairs are respectively connected to two frames. After the carrying frame 1 moves to the specified repair area, in the initial state, both the rolling roller 4 and the excavating roller 3 are in a retracted state, and in the installation of the rolling roller 4 and the excavating roller 3, a layout method with the rolling roller 4 inside and the excavating roller 3 outside is adopted, that is Figure 2 shown, when performing the flattening work, by starting the cylinder 7 corresponding to the rolling roller 4, the cylinder 7 drives the rolling roller 4 to move away from the carrying frame 1, and is staggered from the working horizontal plane of the excavating roller 3, that is Figure 3 shown; when performing the excavation operation, by starting the cylinder 7 corresponding to the excavating roller 3, the cylinder 7 drives the excavating roller 3 to move away from the carrying frame 1, and is staggered from the working horizontal plane of the rolling roller 4, that is Figure 4 shown, and the excavation and flattening operations are respectively carried out.

[0052] The rolling roller 4 and the excavating roller 3 can work independently or in combination. Working independently means that the rolling roller 4 works alone. When it is detected that there is a raised area on the canal surface, by turning on the transmission 401, the transmission 401 drives the rolling roller 4 to rotate. The rolling roller 4 is in rolling contact with the base surface through the elongation of the cylinder 7. On the premise of the movement of the carrying frame 1 and the rotation of the rolling roller 4, the raised base surface is leveled.

[0053] The supporting work means that the excavation roller 3 works first, and the rolling roller 4 follows up. The texture of some raised base surfaces is relatively hard. To facilitate leveling, the transmission 301 drives the excavation roller 3 to rotate. By controlling the corresponding cylinder 7 to extend, the excavation roller 3 is extended to correspond to the raised base surface. When the bearing frame 1 moves, the excavation roller 3 is selected as the forward end. The excavation knives on the excavation roller 3 excavate the raised part, making the hard bulge become looser, and then it is compacted after excavation under the action of the subsequent rolling roller 4. When the rolling roller 4 works, its corresponding cylinder 7 can work synchronously with the cylinder 7 of the excavation roller 3. After the excavation roller 3 excavates the raised part, it is immediately compacted by the rolling roller 4.

[0054] When there is a depression on the base surface, that is, the lining panel takes away a part of the base. By controlling the conveying unit, some sandbags contained in the storage cavity 101 are put through the discharge port 102 to the depressed position of the base surface. After the discharge is completed, the rolling roller 4 is rotated and the bearing frame 1 is controlled to move, driving the rolling roller 4 to roll on the filled sandbags to achieve compaction. After compaction, ensure that the entire base surface is in the same plane, thereby ensuring the quality after the installation of the subsequent new board. The above-mentioned transmission 401 and transmission 301 are preferably pneumatic motors.

[0055] Based on the above solution, to store sandbags more conveniently, as Figure 5 shown in Figure 6 , the conveying unit includes:

[0056] At least two driving cylinders 8, rotatably arranged on the bearing frame 1, and one of the driving cylinders 8 corresponds to the edge of the discharge port 102;

[0057] A bearing belt 801, arranged between the driving cylinders 8;

[0058] A driver 803, used to drive one of the driving cylinders 8 to rotate;

[0059] Partition plates 802, arranged at intervals on the bearing belt 801, and a placement space for placing sandbags is formed between two adjacent partition plates 802.

[0060] The sandbags are stored on the carrying belt 801. The surface of the carrying belt 801 has certain friction bumps, which can increase the friction between the sandbags and prevent the sandbags from moving by themselves. In order to ensure the bearing capacity of the sandbags, multiple drive cylinders 8 are used to increase the bearing area between the carrying belt 801 and the sandbags, so that the sandbags can be better carried. According to the needs of the sandbags, when the sandbags are stored, they can be placed at intervals along the carrying belt 801, so that in the subsequent filling of the depression, the movement of the driver 803 can be controlled according to the size of the depression area, thereby controlling the movement of the carrying belt 801 to select how many sandbags are discharged through the delivery port 102. After reaching the specified number of sandbags, the driver 803 can be stopped to stop the delivery of the sandbags. Among them, the driver 803 can be a motor. Since it needs to work in water, it is necessary to use existing technical means to control the waterproofness of the motor to meet normal work.

[0061] As it moves along the channel surface, the carrying belt 801 will tilt in the direction of the channel surface. In order to further place the sandbags on the carrying belt 801 and move them under the action of gravity, the sandbags to be used are stored one by one in the corresponding placement space. The partition 802 can block the sandbags and prevent them from moving. For example, one placement space stores one sandbag. When only one sandbag is needed in the recessed position, the control driver 803 allows one placement space to pass through the delivery port 102 to complete the delivery of one sandbag.

[0062] Based on the above scheme, if Figure 2 As shown, it also includes a delivery plate 5, which is installed at the bottom of the carrying frame 1 through a rotating mechanism. The rotating mechanism is used to control the inclination angle of the delivery plate 5. Under the action of the delivery plate 5, the cooperation between the delivery plate 5 and the rotating mechanism can play the role of opening and closing the valve. Even if the sandbag at the edge of the carrying belt 801 is separated from the carrying belt 801, it can be intercepted under the action of the delivery plate 5. Then, in the subsequent filling of the sandbags, specifically, Figure 5 As shown, the rotating mechanism includes:

[0063] The rotating rod 502 is rotatably disposed at the bottom of the supporting frame 503;

[0064] A driving motor 501 is used to drive the rotating rod 502 to rotate;

[0065] The slide rail 601 and the slider 602 arranged at the bottom of the carrying frame 1 are used to move the delivery plate 5 along the length direction of the delivery port 102 .

[0066] By starting the drive motor 501, the drive motor 501 drives the rotating rod 502 to rotate. In the initial state, the placement plate 5 is in a horizontal state. When the rotating rod 502 rotates, it can drive the placement plate 5 to tilt downward, so that the sandbags on the placement plate 5 enter the corresponding depressions according to the tilt angle of the placement plate 5. In the same base surface, there may be a situation where the depression is not aligned with the placement plate 5. Therefore, the length of the placement plate 5 is generally half of the length of the placement opening 102, and the placement plate 5 can also move along the length direction of the placement opening 102. In the initial state, the placement plate 5 always corresponds to the end of the conveyor belt 801. During selective placement, the placement plate 5 can be slid along the length direction of the placement opening 102 until the placement plate 5 corresponds to the depression part, and finally control the drive motor 501 to reverse the placement plate 5 to complete the placement of the sandbag.

[0067] To improve the transmission efficiency, a driving member is further included. The driving member is a pneumatic rod 6 or an electric push rod, which is used to push the placement plate 5 to move along the slide rail 601 through the slider 602. When the telescopic end of the pneumatic rod 6 extends, it can drive the placement plate 5 to move towards the hollow direction of the placement opening 102. Moreover, the structure of the placement plate 5 is U-shaped, that is, both sides of the placement plate 5 are bent upward. When the sandbag enters the placement plate 5, it can be blocked by the bent part to prevent the sandbag from falling due to the influence of water flow.

[0068] The embodiment of the present invention also proposes a leveling method for underwater repair operation of the concrete lining panel of the water network channel, including the above leveling equipment for underwater repair operation of the concrete lining panel of the water network channel, and further includes the following steps:

[0069] S1: Move the leveling equipment loaded with sandbags to the leveling area through the loading mechanism;

[0070] S2: Detect the reference surface and judge whether the reference surface is convex or concave;

[0071] S3: If the reference surface is convex, flatten or excavate the convex surface through the leveling unit;

[0072] S4: If the reference surface is concave, put the sandbag into the concave area through the conveying unit and compact it through the leveling unit;

[0073] S5: Repeat the above steps until the leveling operation is completed.

[0074] Specifically, in S1, fill the sandbag into the storage cavity 101, and transport the leveling equipment along the canal surface into the water through the loading mechanism until it is transported to the leveling area and adjusted to the appropriate height;

[0075] In S2, install the detection unit at the bottom of the bearing frame 1 to monitor the canal surface situation in real time;

[0076] In S3, if a raised reference surface is detected, the cylinder 7 corresponding to the rolling roller 4 is activated to move the rolling roller 4 away from the bottom of the bearing frame 1. The bearing mechanism is controlled to drive the leveling equipment to move along the canal surface, and the first transmission 401 is activated to rotate the rolling roller 4 to flatten the raised reference surface.

[0077] Specifically, the leveling unit includes a rolling roller 4 and an excavating roller 3. The flattening or excavating operation is selected according to the hardness of the reference surface. If the raised reference surface cannot be flattened, the cylinder 7 corresponding to the rolling roller 4 is retracted, the cylinder 7 corresponding to the excavating roller 3 is activated, the excavating roller 3 is moved away from the bottom of the bearing frame 1, and the excavating roller 3 is driven to rotate by the transmission 301 to excavate the raised reference surface that cannot be flattened, and then the rolling is repeated.

[0078] In S4, if a sunken reference surface is detected, the sandbags in the storage cavity 101 are discharged through the discharge port 102 to the sunken area by the conveying unit, and the rolling in S3 is repeated. At the same time, the conveying unit separates the sandbags through the partition 802 and controls the quantity of sandbags discharged according to the size of the sunken area.

[0079] In this method, through the coordinated work of the bearing mechanism, the rolling roller 4, the excavating roller 3 and the conveying unit, the integrated operation from detection to repair is realized, avoiding the cumbersome process of traditional manual step-by-step operation. At the same time, according to the raised or sunken condition of the reference surface, different treatment methods (flattening, excavating or filling) can be quickly switched, significantly shortening the repair time and solving the problems of low efficiency, poor accuracy, high risk, material waste, etc. existing in traditional underwater base leveling operations.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
