Description

Technical Field

[0001] This utility model belongs to the field of rubber dam technology, and in particular relates to a rubber dam bag anchoring device. Background Technology

[0002] A rubber dam is a water-retaining structure that uses a rubberized sheet made of fiber fabric and rubber as a dam bag, which is then anchored to the dam foundation and end walls. The height of a rubber dam can be adjusted as needed to control the overflow at the dam crest and the upstream water level. It features a novel structure and convenient management, and is widely used in flood control, irrigation, urban and rural water supply, hydropower generation, and environmental beautification.

[0003] In existing technologies, the bolt-and-plate anchoring method is commonly used to anchor rubber dam bags. Specifically, bolts and washers are first cast into the dam foundation, then holes are drilled in the rubber dam bag and bolts are passed through. Finally, a pressure plate is pressed onto the top of the rubber dam bag, clamping it between the washers and the pressure plate, thus anchoring the rubber dam bag. However, this method involves drilling holes in the rubber dam bag, which damages its framework. The rubber dam bag is easily torn or detached from the bolts, affecting the anchoring effect. Furthermore, because the washers are fixed to the dam foundation through concrete casting, replacing them later is difficult and can lead to damage to the dam foundation. Utility Model Content

[0021] This invention provides a rubber dam bag anchoring device. A support frame is fixed to the foundation of the rubber dam, and a pad is detachably installed on the support frame. The pad is fixed to the foundation via the support frame, allowing for easy removal of the pad from the support frame during replacement without damaging the foundation, thus ensuring its strength.

When the clamping member moves along the clamping direction, it contacts and pushes against the pressure plate, pressing the rubber dam bag between the pad and the pressure plate against the pad, thereby fixing the rubber dam bag to the foundation. In other words, fixing the rubber dam bag by clamping avoids drilling holes in the bag, ensuring its strength and preventing tearing or detachment. This results in a rubber dam with good water-blocking capacity and reliable operation. Attached Figure Description

[0036] It should be understood that in the description of this utility model, the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0037] It should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] like Figures 1 to 7 As shown, this embodiment provides a rubber dam bag anchoring device. The pad 2 is easy to install and remove without damaging the dam foundation 100. Moreover, the rubber dam bag 200 can be fixed to the dam foundation 100 without drilling holes in it, which improves the service life of the rubber dam bag 200.

[0040] See Figure 1 and Figure 2 The rubber dam bag anchoring device includes a support frame 1, a pad 2, a pressure plate 3, and a clamping device along the pressing direction ( Figure 2The clamping member 4 is movably installed on the support frame 1 in the negative X direction. The support frame 1 can be fixed to the dam base 100 of the rubber dam. The pad 2 is detachably installed on the support frame 1. The rubber dam bag 200 is placed between the pad 2 and the pressure plate 3. When the clamping member 4 is driven to move in the clamping direction, the clamping member 4 can contact the pressure plate 3 and push the pressure plate 3 to press the rubber dam bag 200 onto the pad 2.

[0041] The rubber dam bag anchoring device provided in this embodiment has a support frame 1 fixed to the dam foundation 100 of the rubber dam. The pad 2 is detachably installed on the support frame 1, that is, the pad 2 is fixed to the dam foundation 100 through the support frame 1. This allows the pad 2 to be removed from the support frame 1 when it is replaced, without damaging the dam foundation 100, thus ensuring the strength of the dam foundation 100. Moreover, since the dam foundation 100 is made of concrete, separating the pad 2 from the support frame 1 is more convenient and faster than separating the pad 2 from the concrete. When the clamping member 4 moves along the clamping direction, the clamping member 4 contacts and pushes against the pressure plate 3, so that the rubber dam bag 200 located between the pad 2 and the pressure plate 3 is pressed against the pad 2 by the pressure plate 3, thereby fixing the rubber dam bag 200 to the dam foundation 100. That is, by fixing the rubber dam bag 200 by compression, it is possible to avoid drilling holes in the rubber dam bag 200, thus ensuring the strength of the rubber dam bag 200 itself and preventing the rubber dam bag 200 from tearing or falling off. This gives the rubber dam good water-blocking ability and makes it reliable in use.

[0042] For example, the support frame 1, pad 2, pressure plate 3 and clamping member 4 are all made of steel, which is strong and not easily deformed.

[0043] Optionally, see Figure 2The support frame 1 includes a first mounting arm 11 and a second mounting arm 12 arranged at intervals along the pressing direction. The pad 2 is mounted on the second mounting arm 12. The pressing component 4 includes a screw 41 and a pressure block 42. The pressure block 42 is located on the side of the first mounting arm 11 facing the pad 2. One end of the screw 41 is threaded to the first mounting arm 11, and the other end is rotatably connected to the pressure block 42. The pressure block 42 can be circumferentially limited to the pressure plate 3. When the screw 41 is driven to rotate, the screw 41 can push the pressure block 42 against the pressure plate 3 along the pressing direction. The spaced first mounting arm 11 and second mounting arm 12 provide space for the movement of the clamping member 4 and the installation of the rubber dam bag 200. The threaded connection between the lead screw 41 and the first mounting arm 11 not only restricts the movement direction of the lead screw 41, allowing it to move only in the clamping direction, but also controls the distance and position of the lead screw 41's movement by controlling its rotation, so that the rubber dam bag 200 can always be in a clamped state. The setting of the pressure block 42 increases the contact area between the clamping member 4 and the pressure plate 3, improving the clamping effect of the clamping member 4 on the pressure plate 3. The rotatable connection between the lead screw 41 and the pressure block 42 ensures that during the clamping process, only the lead screw 41 rotates, and the pressure block 42, which is pushed by the lead screw 41, does not rotate with the lead screw 41. Under the pressure of the pressure block 42, the pressure plate 3 can only move in the clamping direction.

[0044] Specifically, in the initial state, there is a certain gap between the pressure block 42 and the pad 2. After the rubber dam bag 200 is placed between the pad 2 and the pressure plate 3, the screw 41 is turned so that the screw 41 moves in the pressing direction (closer to the pressure plate 3). The pressure block 42 moves synchronously with the screw 41. When the pressure block 42 contacts the pressure plate 3, when the screw 41 is turned, the screw 41 pushes the pressure block 42 against the pressure plate 3 in the pressing direction until the screw 41 can hardly rotate anymore. The pressure block 42 presses the pressure plate 3, so that the rubber dam bag 200 is firmly pressed between the pressure plate 3 and the pad 2.

[0045] Further, see Figure 2 An operating part 411 is provided at the end of the lead screw 41 that is connected to the first mounting arm 11. The operating part 411 is located on the side of the first mounting arm 11 away from the second mounting arm 12. The lead screw 41 can be rotated by turning the operating part 411, which makes it convenient for the operator to drive the lead screw 41.

[0046] For example, the lead screw 41 is the screw part of the bolt, and the operating part 411 is the head of the bolt.

[0047] Optionally, see Figure 2 and Figure 3 The pressure plate 3 is provided with a first groove 31, and the pressure block 42 can be inserted into the first groove 31 along the pressing direction and circumferentially limited to the first groove 31 to prevent the pressure plate 3 from moving during the pressing process.

[0048] Specifically, the cross-sectional shape of the pressure block 42 is polygonal, and the cross-sectional shape of the first groove 31 is a polygonal shape that matches the pressure block 42. During the rotation of the lead screw 41, the groove wall of the first groove 31 can contact the side wall of the pressure block 42 and hinder the rotation of the pressure block 42, so that the pressure block 42 can be circumferentially limited to the first groove 31. Similarly, under the action of the force between the groove wall of the first groove 31 and the side wall of the pressure block 42, the displacement of the pressure plate 3 can be restricted.

[0049] For example, see Figure 2 and Figure 3 The first groove 31 is provided on the pressure plate 3 along its width direction. Figure 3 The pressure plate 3 is positioned in the middle of the Y direction, so that it can be evenly stressed along its width, thus ensuring the compression effect on the rubber dam bag 200.

[0050] Optionally, the first mounting arm 11 is provided with a threaded hole that extends along the pressing direction to limit the movement direction of the lead screw 41; the pressure block 42 is provided with a rotating groove 43, one end of the lead screw 41 is threadedly engaged with the threaded hole, and the other end is rotatably mounted in the rotating groove 43, so that the lead screw 41 and the pressure block 42 can rotate together, and the lead screw 41 can only drive the pressure block 42 to move, but cannot drive the pressure block 42 to rotate.

[0051] In this embodiment, see Figure 4 Two limiting plates 44 are spaced apart on the pressure block 42, forming a rotating groove 43 around it. A stop 45 is provided at the other end of the lead screw 41, which engages with and rotates within the rotating groove 43. When the pressure block 42 contacts the pressure plate 3, the lead screw 41 continues to rotate, causing the stop 45 to rotate within the rotating groove 43. The limiting plates 44 do not rotate with the lead screw 41, meaning the pressure block 42 does not rotate, allowing it to move only in the pressing direction under the action of the lead screw 41. Furthermore, the stop 45 prevents the other end of the lead screw 41 from disengaging from the rotating groove 43 during movement without affecting its rotation.

[0052] Furthermore, in this embodiment, the rotating groove 43 includes a first rotating groove and a second rotating groove that are connected to each other. The first rotating groove is located between the two limiting plates 44, and the second rotating groove is disposed on the pressure block 42 and is directly opposite the threaded hole. Figure 4As shown, when the pressure block 42 is not in contact with the pressure plate 3, there is a certain gap between the lower end of the screw 41 and the pressure block 42. Rotating the screw 41 moves the pressure block 42 until it engages with the first groove 31. The pressure block 42 is then circumferentially confined to the pressure plate 3 by the first groove 31. Continuing to rotate the screw 41 causes it to rotate within the first rotating groove. When the screw 41 extends downward into the second rotating groove and contacts the bottom wall of the second rotating groove, further rotation of the screw 41 pushes the pressure block 42 downward, pressing it tightly against the pressure plate 3. The lower end of the screw 41 rotates in conjunction with the second rotating groove. The second rotating groove prevents the pressure block 42 from moving relative to the screw 41, restricting its movement to the pressing direction only.

[0053] In some embodiments, the end face of the other end of the lead screw 41 directly abuts against the surface of the pressure block 42 to push the pressure block 42 to move.

[0054] Optionally, see Figure 4 The limiting plate 44 includes a first plate 441 and a second plate 442 arranged at an angle. The first plate 441 is fixedly connected to the pressure block 42. The second plates 442 of the two limiting plates 44 extend toward each other, forming a through-hole 431 between them. The lead screw 41 is movably inserted through the through-hole 431. When the lead screw 41 moves in the opposite direction of the pressing direction ( Figure 4 When the X direction is positive, the stop part 45 can contact the second plate 442, preventing the other end of the screw 41 from disengaging from the rotating groove 43. It also allows the pressure block 42 to not only move towards the pressure plate 3 under the push of the screw 41, but also move away from the pressure plate 3 along with the screw 41 through the limiting plate 44 and the stop part 45.

[0055] For example, see Figure 4 The through-hole 431 is fitted with the lead screw 41 with a clearance to prevent the limiting plate 44 from affecting the rotation and movement of the lead screw 41.

[0056] Optionally, the stop part 45 includes a stop ring plate coaxially disposed at the other end of the lead screw 41. The stop ring plate can be engaged into the rotating groove 43 through the side slot 432 of the rotating groove 43, so as to provide sufficient assembly space for the connection between the stop ring plate and the lead screw 41, which facilitates the assembly of the rubber dam bag anchoring device on the construction site and is quick and convenient to operate. The side of the stop ring plate is arc-shaped, so that the limiting plate 44 will not hinder the rotation of the stop ring plate during the rotation of the lead screw 41, thus preventing the lead screw 41 from disengaging from the rotating groove 43 while not affecting the rotation of the lead screw 41.

[0057] Specifically, when assembling the rubber dam bag anchoring device, first pass the lead screw 41 through the threaded hole of the first mounting arm 11, then connect the stop ring plate to the lead screw 41, and then align the lower end of the lead screw 41 with the side groove 432 of the rotating groove 43, so that the stop ring plate is inserted into the rotating groove 43 through the side groove 432, and at the same time the lead screw 41 is inserted into the through hole 431 through the side groove 432, thus completing the assembly of the pressure block 42 and the lead screw 41.

[0058] Additionally, refer to Figure 4 In terms of orientation, since there is a certain gap between the lower end of the lead screw 41 and the pressure block 42, that is, after the stop ring plate is installed on the lead screw 41, the length between the upper end face of the stop ring plate and the lower end face of the lead screw 41 is less than the height of the rotating groove 43. This allows the lower end of the lead screw 41 and the stop ring plate to smoothly engage in the rotating groove 43 when assembling the lead screw 41 and the pressure block 42, thereby improving the ease of assembly of the lead screw 41 and the pressure block 42.

[0059] Furthermore, a gap is formed between the stop ring plate and the two first plates 441 to allow the stop ring plate to rotate within the rotating groove 43; the inner wall of the stop ring plate is provided with a thread that engages with the lead screw 41; the lead screw 41 is provided with a positioning hole 412 and a positioning element; the positioning hole 412 is located on the side of the stop ring plate away from the second plate 442; the positioning element can be fastened in the positioning hole 412 to fix the position of the stop ring plate on the lead screw 41 and prevent the stop ring plate from dislodging from the lead screw 41.

[0060] For example, the positioning element is a pin, and the positioning hole 412 is a hole that passes through the lead screw 41 along its diameter.

[0061] In other embodiments, the stop ring plate is fixedly connected to the lead screw 41 by welding or other means, so that the position of the stop ring plate on the lead screw 41 can be fixed without setting the positioning hole 412 and positioning parts.

[0062] In an optional embodiment, see [link to relevant documentation] Figure 2 and Figure 6 The support frame 1 includes a connector 14 and two components extending along the direction of the pad 2. Figure 7 The support members 13 are arranged at intervals in the Z direction. The two ends of the connector 14 are respectively connected to the two support members 13. Each support member 13 is provided with a connecting arm 131, an upper mounting arm 132 and a lower mounting arm 133. The two ends of the connecting arm 131 are fixedly connected to the upper mounting arm 132 and the lower mounting arm 133 respectively. The two upper mounting arms 132 form the first mounting arm 11, and the two lower mounting arms 133 form the second mounting arm 12. A nut seat 15 is provided between the two upper mounting arms 132. The lead screw 41 is threadedly engaged with the nut seat 15. The threaded hole on the nut seat 15 is the same as the threaded hole of the first mounting arm 11.

[0063] Two support members 13 are arranged at intervals along the extension direction of the pad 2, and the two are connected and fixed using connectors 14. Compared with the structural design of a single support member 13, this enhances the overall structural strength of the support frame 1, prevents deformation of the support frame 1 during the compression process, ensures the firmness of the compression of the rubber dam bag 200, and improves the reliability of the rubber dam. At the same time, designing the support frame 1 as a structure of two support members 13 spliced ​​together, rather than a solid structure, can save the amount of material used in manufacturing the support frame 1 and reduce the manufacturing cost of the support frame 1.

[0064] For example, see Figure 2 and Figure 6 The support frame 1 has a C-shaped cross-section and is made of steel. The nut seat 15 is welded to the two upper mounting arms 132. The connecting member 14 is a steel plate, and the clamping direction is vertical. The connecting member 14 includes a first steel plate 141, a second steel plate 142, and a third steel plate 143. The two ends of the first steel plate 141 are respectively welded to the two upper mounting arms 132 facing each other. The two ends of the second steel plate 142 are respectively welded to the two connecting arms 131 facing each other. The two ends of the third steel plate 143 are respectively welded to the two lower mounting arms 133 facing each other, so that the two C-shaped support members 13 can be evenly and firmly connected together.

[0065] Furthermore, the bottom surface of the third steel plate 143 is flush with the lower surface of the second mounting arm 12, so that the concrete can be poured onto the third steel plate 143 when the support frame 1 is poured, thereby ensuring the stability of the support frame 1 on the dam foundation 100.

[0066] In another optional embodiment, the support frame 1 is a C-shaped support block, and the two vertically opposite limbs of the C-shaped support block are the first mounting arm 11 and the second mounting arm 12, respectively.

[0067] Optionally, see Figure 2 and Figure 5 The support frame 1 is provided with a second groove 16, and the pad 2 can be fitted into the second groove 16. The sidewall of the second groove 16 can be in the width direction of the pad 2. Figure 5 The upper limit pad 2 (in the Y direction) is used to prevent the pad 2 from moving during the clamping process. When pouring concrete, the concrete is poured to be flush with the bottom wall of the second groove 16, which fixes the support frame 1 without affecting the installation of the pad 2. When replacing the pad 2 later, the pad 2 can be directly removed from the support frame 1, and the new pad 2 can be directly placed into the second groove 16. The replacement of the pad 2 is convenient and will not damage the dam foundation 100.

[0068] Furthermore, to facilitate the installation of the pad 2, the dimension of the second groove 16 along the width direction of the pad 2 is greater than the width of the pad 2, that is, a gap is formed between the side wall of the pad 2 embedded in the second groove 16 and the side groove wall of the second groove 16.

[0069] For example, the gap between the side wall of the pad 2 and the side groove wall of the second groove 16 ranges from 1 mm to 3 mm.

[0070] Optionally, see Figure 2 The pad 2 has multiple convex structures 21 spaced apart along its width on the side facing the pressure plate 3, and the pressure plate 3 has multiple third grooves 33 spaced apart along its width on the side facing the pad 2. Each convex structure 21 corresponds to one of the third grooves 33. When the rubber dam bag 200 is pressed between the pad 2 and the pressure plate 3, the convex structures 21 and the third grooves 33 work together to compress the rubber dam bag 200 into a curved shape, increasing the contact area between the rubber dam bag 200 and the pad 2 and pressure plate 3, thus preventing the rubber dam bag 200 from detaching from the pad 2 and pressure plate 3. Simultaneously, the surface of the convex structures 21 and the groove wall of the third grooves 33 generate a frictional force on the rubber dam bag 200 at an angle to the horizontal direction, rather than just a horizontal frictional force, thereby improving the clamping strength of the pad 2 and pressure plate 3 on the rubber dam bag 200.

[0071] For example, see Figure 2 The convex hull structure 21 is oriented towards the pressure plate 3 ( Figure 2 The pad 2 has an arc-shaped structure protruding in the X-direction, and two convex structures 21 are provided on the pad 2, which are located at both ends of the pad 2 along its width direction; the third groove 33 is directed towards the first mounting arm 11 (in the X-direction). Figure 2 The pressure plate 3 has an arc-shaped groove (in the positive X direction) and two third grooves 33, which are located at both ends of the pressure plate 3 along its width direction.

[0072] The pressure plate 3 has a third recess 33, which forms a bulge on the side of the pressure plate 3 facing away from the pad 2. A fourth recess 32 is formed between the two bulges of the pressure plate 3. In this embodiment, the bottom surface of the first recess 31 is flush with the bottom surface of the fourth recess 32, and the dimension of the first recess 31 along the width direction of the pressure plate 3 is larger than the width of the fourth recess 32. This avoids the presence of the first recess 31 from excessively weakening the strength of the pressure plate 3, preventing deformation or even breakage of the pressure plate 3, and ensuring the pressing effect. At the same time, it also allows the pressure block 42 to be engaged in the first recess 31, ensuring the circumferential limiting effect of the first recess 31 on the pressure block 42.

[0073] In other embodiments, if the thickness of the pressure plate 3 is sufficient, the first groove 31 can also be directly recessed on the top surface of the pressure plate 3, without the width of the first groove 31 being greater than the width of the fourth groove 32.

[0074] For example, the cross-sectional shape of the first groove 31 is rectangular.

[0075] Optionally, see Figure 1 and Figure 5The rubber dam bag anchoring device also includes anchors 5 anchored to the dam foundation 100, so that the rubber dam bag anchoring device can be firmly anchored to the dam foundation 100; a connecting plate 17 is provided on the support frame 1, and the connecting plate 17 is detachably connected to the anchors 5, which facilitates the installation of the support frame 1 and the anchors 5.

[0076] In this embodiment, the anchor 5 is an anchor bolt, and the third steel plate 143 of the support frame 1 is integrated with the connecting plate 17, so that the concrete can be poured into the third steel plate 143 at the same time as the connecting plate 17, which improves the firmness of the connection between the anchor 5 and the support frame 1.

[0077] Optionally, see Figure 5 The rubber dam bag anchoring device also includes fasteners 6 and adjusting components 7. The anchor 5 includes a screw part, and the connecting plate 17 is provided with an installation hole. The screw part passes through the installation hole. The fasteners 6 and adjusting components 7 are threadedly engaged with the screw part and are respectively located on both sides of the connecting plate 17. The fasteners 6 and adjusting components 7 work together to fix the connecting plate 17 to the screw part.

[0078] Specifically, the adjusting member 7 is located below the connecting plate 17, and can support the connecting plate 17 when it is installed. By adjusting the position of the adjusting member 7 on the screw section, the position of the connecting plate 17 on the screw section can be adjusted. The fastener 6 is located above the connecting plate 17. After the connecting plate 17 passes through the mounting hole, the fastener 6 is installed. The fastener 6 can press against the connecting plate 17, thereby fixing the connecting plate 17.

[0079] For example, fastener 6 includes a locking nut located above connecting plate 17, and adjusting member 7 includes an adjusting nut located below connecting plate 17 to fix the position of connecting plate 17 on the screw portion. The rubber dam bag anchoring device also includes an anti-loosening nut 8. When connecting support frame 1 to anchor 5, the adjusting nut is first installed on the screw portion, then the screw portion passes through the mounting hole of connecting plate 17, and then the locking nut and anti-loosening nut 8 are sequentially tightened above connecting plate 17. The anti-loosening nut 8 and locking nut are in close contact and can generate friction, which can be converted into a tightening torque between the anti-loosening nut 8 and the screw portion, and between the locking nut and the screw portion, thereby improving the reliability of the connection; that is, the anti-loosening nut 8 effectively prevents the locking nut from loosening.

[0080] Optionally, see Figure 2 The rubber dam bag anchoring device also includes an anti-detachment shaft 9, which is located on the side of the pad 2 away from the rubber dam and is used to prevent the rubber dam bag 200 from detaching from the pad 2 and the pressure plate 3.

[0081] Specifically, when laying the rubber dam bag 200, the rubber dam bag 200 is laid on the pad 2 from the side closest to the rubber dam to the side furthest from the rubber dam (along the... Figure 2(The negative direction of Y), then, let the rubber dam bag 200 go around the anti-detachment shaft 9 and bend back to the side close to the rubber dam. Wherein, the diameter of the anti-detachment shaft 9 is not less than the distance between the pad 2 and the pressure plate 3 after the rubber dam bag 200 is pressed tightly against the pad 2.

[0082] Optionally, see Figure 7 Along the length direction of pad 2 ( Figure 7 In the Z direction, multiple support frames 1, multiple clamping parts 4 and multiple anchors 5 are arranged at intervals. Each of the multiple clamping parts 4 and multiple anchors 5 corresponds to one of the multiple support frames 1, so that all parts of the rubber dam bag 200 along the length of the pad 2 can be clamped.

[0083] Optionally, see Figure 2 Bottom gaskets 10 are provided between the rubber dam bag 200 and the pressure plate 3, and between the rubber dam bag 200 and the pad 2, to protect the rubber dam bag 200 and reduce wear between the rubber dam bag 200 and the pad 2 and the pressure plate 3.

[0084] For example, the bottom pad 10 is made of rubber, which has strong corrosion resistance and wear resistance.

[0085] The process of anchoring the rubber dam bag 200 using the rubber dam bag anchoring device of this embodiment is as follows:

[0086] S1. After the foundation pit of 100mm dam foundation is excavated, install anchor 5 in the foundation pit;

[0087] S2. Install the adjusting piece 7, the connecting plate 17 and the fastener 6 in sequence on the anchor 5 to connect the support frame 1 to the anchor 5.

[0088] S3. Pour concrete into the foundation pit until the top surface of the concrete is flush with the bottom wall of the second groove 16, so as to fix the anchor 5 and the support 13 to the dam foundation 100 while forming the dam foundation 100.

[0089] S4. Insert the pad 2 into the second groove 16;

[0090] S5. Lay the bottom pad 10 under the rubber dam bag 200; on the pad plate 2, lay the bottom pad 10 together with the rubber dam bag 200 from the side closest to the rubber dam to the side furthest from the rubber dam (along... Figure 2 (Negative direction of Y), then, place the anti-detachment shaft 9 on the rubber dam bag 200, and position it on the side of the pad 2 away from the rubber dam. Then, wrap the bottom pad 10 around the anti-detachment shaft 9 along with the rubber dam bag 200 and bend it back to the side close to the rubber dam. That is, between the first mounting arm 11 and the second mounting arm 12, from bottom to top, are the pad 2, the bottom pad 10, two layers of rubber dam bags 200 and the bottom pad; S6, place the pressure plate 3 on the side of the bent bottom pad 10 away from the pad 2, and make the multiple convex structures 21 correspond one-to-one with the multiple third grooves 33;

[0091] S7. Drive the lead screw 41 to rotate. The lead screw 41 drives the pressure block 42 to move along the pressing direction and move the pressure plate 3 horizontally so that the pressure block 42 is opposite to the first groove 31 and gradually gets into the first groove 31. Continue to drive the lead screw 41 to rotate until the rubber dam bag 200 is pressed tightly against the pad 2 by the pressure plate 3.
