[0001] The utility model belongs to the field of water stopping and anti-seepage of concrete construction joints, in particular to a water stopping and anti-seepage device for cantilever retaining wall construction joints. Background Art
[0002] During the construction of cantilever retaining walls, it is difficult and costly to cast the retaining wall base plate and wall body at the same time, and the quality cannot be guaranteed. Therefore, the multi-stage casting process is adopted, first casting the base plate and then casting the wall body. The multi-stage casting process will cause construction joints in the cantilever retaining wall. The existence of construction joints leads to the risk of water leakage in the wall body.
[0003] The solution in the prior art is to embed rubber waterstops, waterstop strips or waterstop steel plates at the construction joints before pouring the bottom slab concrete for the first time. It is difficult to fix the embedded rubber waterstops or waterstop strips. During the pouring construction process, the rubber waterstops or waterstop strips are prone to deflection, damage, etc., and lose their anti-seepage effect on the construction joints, thus posing a safety hazard to the cantilever retaining wall. Although the waterstop steel plates do not have the above problems, most of the existing waterstop steel plates are single-body structures, and their overall reinforcement structures are mostly complex. If the welding is not firm, it is easy to leak, affecting the waterproof effect. Summary of the invention

[0031] See attached Figures 1 to 4 , a schematic embodiment of the water-stopping and anti-seepage device for the construction joint of a cantilever retaining wall proposed by the utility model is given. The water-stopping and anti-seepage device for the construction joint of a cantilever retaining wall is composed of a first water-stopping steel plate 1, a second water-stopping steel plate 2 and a positioning rib 5.
[0032] The first waterstop steel plate 1 and the second waterstop steel plate 2 are arranged in parallel, and the first waterstop steel plate 1 and the second waterstop steel plate 2 have the same structure, and are respectively composed of a main steel plate 3 and a wing steel plate 4, wherein the main steel plate 3 is provided with one, and the wing steel plates 4 are provided with two, the main steel plate 3 and the wing steel plates 4 are both rectangular sheets, the two wing steel plates 4 are provided at both ends of the main steel plate 3, and the two wing steel plates 4 are bent to the same side so that the cross-sections of the first waterstop steel plate 1 and the second waterstop steel plate 2 are open trapezoidal, and the trapezoidal opening of the cross-section of the first waterstop steel plate 1 and the trapezoidal opening of the cross-section of the second waterstop steel plate 2 are in the same direction.
[0033] In order to improve the stability of the first waterstop steel plate 1 and the second waterstop steel plate 2 arranged in parallel, the water-stopping and anti-seepage device for the construction joint of the cantilever retaining wall of this embodiment includes positioning ribs 5, which are arranged between the first waterstop steel plate 1 and the second waterstop steel plate 2. The positioning ribs 5 are fixed on the main steel plate 3 of the first waterstop steel plate 1 and the main steel plate 3 of the second waterstop steel plate 2, so that the positions of the first waterstop steel plate 1 and the second waterstop steel plate 2 are relatively stable.
[0034] See attached Figure 3 In order to ensure the waterproof and anti-seepage effect, the main steel plate 3 and the wing steel plate 4 are rectangular sheets of the same length. The length of the main steel plate 3 and the wing steel plate 4 is determined according to the length of the construction joint 61 in actual construction. When the main steel plate 3 is longer, in order to ensure the stability of the relative position of the first waterproof steel plate 1 and the second waterproof steel plate 2, see the attached Figure 2 A plurality of positioning ribs 5 are arranged at intervals along the length direction of the main steel plate 3, and a plurality of positioning ribs 5 arranged at intervals along the length direction of the main steel plate 3 constitute a layer of positioning ribs 5. In this embodiment, seven positioning ribs 5 are arranged at intervals along the length direction of the main steel plate 3, and the spacing between adjacent positioning ribs 5 is the same.
[0035] See attached Figure 1 In order to further improve the overall stability of the device, the positioning ribs 5 are arranged in multiple layers along the width direction of the main steel plate 3, and the multiple layers of positioning ribs 5 are arranged symmetrically along the width direction of the main steel plate 3. In this embodiment, the positioning ribs 5 are arranged in two layers along the width direction of the main steel plate 3.
[0036] In order to firmly connect the positioning ribs 5 to the main steel plate 3, in this embodiment, the positioning ribs 5 are fixed to the main steel plate 3 of the first waterstop steel plate 1 and the main steel plate 3 of the second waterstop steel plate 2 by welding. Welding has the advantages of high quality and low cost, can ensure connection strength and stability, and has high reliability.
[0037] In order to ensure that the water-stopping and anti-seepage device for the construction joint of the cantilever retaining wall does not shift or deform during the construction process, in this embodiment, the positioning rib 5 is selected as a plain round steel bar with a diameter of 14 mm, and the main steel plate 3 and the wing steel plate 4 are selected as a stainless steel plate with a thickness of 10 mm, so as to be able to bear the force during the construction process. Figure 4 During construction, the waterproof and anti-seepage device is placed at the construction joint 61 of the cantilever retaining wall 6. The first waterproof steel plate 1 and the second waterproof steel plate 2 will contact the steel bars in the cantilever retaining wall 6, and the contact points will be welded to ensure that the device does not shift during the construction process.
[0038] In order to improve the waterproof and anti-seepage effect of the device, in this embodiment, the trapezoidal opening of the cross section of the first waterproof steel plate 1 and the trapezoidal opening of the cross section of the second waterproof steel plate 2 are oriented toward the water-facing side, and the bending angles of the two wing steel plates 4 relative to the main steel plate 3 are acute angles, thereby achieving better waterproof and anti-seepage. In this embodiment, the bending angles of the two wing steel plates 4 relative to the main steel plate 3 are 40°.
[0039] In order to extend the service life of the device, in this embodiment, the first water-stop steel plate 1, the second water-stop steel plate 2 and the positioning rib 5 are all provided with an anti-corrosion layer. The anti-corrosion layer specifically consists of three parts: the first layer is a primer applied to the first water-stop steel plate 1, the second water-stop steel plate 2 and the positioning rib 5 to enhance the adhesion with the main coating; the second layer is the main coating, which can be selected from coal tar enamel, petroleum asphalt, polyethylene adhesive tape, epoxy resin or polyolefin coating, etc.; the third layer is a binding tape to maintain a certain mechanical strength to avoid damage during transportation and construction.
[0040] In the above-mentioned schematic embodiment, the water-stopping and anti-seepage device for the construction joint of the cantilever retaining wall is composed of a first water-stopping steel plate, a second water-stopping steel plate and positioning ribs, which has a simple structure and is easy to install. The positioning ribs are arranged in multiple layers along the length direction of the main steel plate and in multiple layers along the width direction of the main steel plate, thereby improving the overall stability of the water-stopping and anti-seepage device and ensuring that the water-stopping and anti-seepage device will not shift during the pouring construction process. The first water-stopping steel plate and the second water-stopping steel plate form a double-layer waterproof structure, which can effectively achieve water-stopping and anti-seepage at the construction joint.
[0041] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
