Description

Technical Field

[0001] This utility model relates to the field of diaphragm wall construction technology, specifically providing a foldable diaphragm wall anti-bypass device. Background Technology

[0002] Currently, in the construction of diaphragm wall sections, the width of the I-beams is smaller than the width of the trench, which can easily cause flow around the concrete, affecting the pouring quality. To address this, most construction methods involve welding grout-stopping sheets to the side of the I-beams in the trench section, ensuring the sheets are parallel to the side of the reinforcing cage. The grout-stopping sheets are then lowered into the trench along with the reinforcing cage and the I-beams. During concrete pouring, the pressure of the concrete forces the grout-stopping sheets against the trench wall, preventing concrete from flowing around the I-beams and the trench wall.

[0003] In actual construction, the grout-stopping sheet may collide with the tank wall during the lowering process, resulting in varying degrees of deformation or folding, which leads to an unsatisfactory anti-flow effect. Utility Model Content

[0014] Furthermore, the first rotating rod and the second rotating rod are of the same length, and the mounting holes of the rotating shaft in the first support plate are correspondingly provided with the mounting holes of the rotating shaft in the second support plate; the mounting holes of the rotating shaft in the pull rod are arranged at equal intervals, and the distance between the mounting holes of two adjacent rotating shafts in the pull rod is the same as the distance between the mounting holes of two adjacent rotating shafts in the first support plate.

[0015] Furthermore, grooves are provided on the sides of the first support plate and the second support plate that are close to each other, and the rotating shaft is disposed in the grooves;

[0016] The first rotating rod has a through hole at one end that is rotatably connected to the first support plate and is inserted into the groove of the first support plate, with the rotating shaft located in the through hole of the first rotating rod;

[0017] The second rotating rod has a through hole at one end that is rotatably connected to the second support plate and is inserted into the groove of the second support plate. The rotating shaft is located in the through hole of the second rotating rod.

The mounting groove and the protrusion are adapted to each other, and mounting holes for the rotating shaft to pass through are provided in the mounting groove and the protrusion.

[0022] The beneficial effects of this utility model are as follows:

[0023] The foldable diaphragm wall anti-flow device provided by this utility model retracts into a folded state when the reinforcing cage is lowered into the trench by pulling a rod, thus avoiding the deformation caused by collision with the trench wall when open.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] The following is combined with Figures 1 to 5 The embodiments shown illustrate the technical solution of this utility model:

[0035] This utility model embodiment provides a foldable ground-connected wall anti-flow device, such as... Figures 1 to 5As shown, it includes: a folded grout-stopping plate 1, a first rotating rod 2, a second rotating rod 3, a rotating shaft 4, a tie rod 5, a first support plate 6, and a second support plate 7, wherein:

[0036] The foldable grout stop plate 1 includes an upper edge and a lower edge along the folding direction. The upper edge of the foldable grout stop plate 1 is fixedly connected to the first support plate 6, and the lower edge of the foldable grout stop plate 1 is fixedly connected to the second support plate 7.

[0037] A first rotating rod 2 is rotatably connected between the first support plate 6 and the pull rod 5. The first support plate 6 and one end of the first rotating rod 2 are rotatably connected by a rotating shaft 4, and the pull rod 5 and the other end of the first rotating rod 2 are rotatably connected by a rotating shaft 4.

[0038] A second rotating rod 3 is rotatably connected between the second support plate 7 and the tie rod 5. One end of the second support plate 7 and the second rotating rod 3 are rotatably connected via a rotating shaft 4, and the other end of the tie rod 5 and the second rotating rod 3 are also rotatably connected via a rotating shaft 4. Before the foldable diaphragm wall anti-flow device provided by this utility model is placed into the trench, the side of the second support plate 7 away from the tie rod 5 needs to be welded to the side of the trench section joint 8 near the trench wall. In this embodiment, the trench section joint 8 is made of I-beam steel.

[0039] The foldable diaphragm wall anti-flow device provided by this utility model can realize the folding and opening of the foldable grout stop plate 1 by pulling the pull rod 5. When the foldable grout stop plate 1 is opened, it can prevent concrete from passing through, thereby playing the role of preventing flow around.

[0040] In some examples, the first rotating rod 2 and the second rotating rod 3 are of the same length, and the mounting holes of the rotating shaft 4 in the first support plate 6 correspond to the mounting holes of the rotating shaft 4 in the second support plate 7; the mounting holes of the rotating shaft 4 in the pull rod 5 are arranged at equal intervals, and the distance between two adjacent mounting holes of the rotating shaft 4 in the pull rod 5 is the same as the distance between two adjacent mounting holes of the rotating shaft 4 in the first support plate 6; similarly, because the mounting holes of the rotating shaft 4 in the first support plate 6 correspond to those in the second support plate 7, the distance between two adjacent mounting holes of the rotating shaft 4 in the pull rod 5 is the same as the distance between two adjacent mounting holes of the rotating shaft 4 in the second support plate 7. When the pull rod 5 is pulled, the first support plate 6 and the second support plate 7 move inward or outward synchronously, thereby realizing the opening or folding of the foldable grout stop plate 1.

[0041] See in some examples Figure 2Both the first support plate 6 and the second support plate 7 have grooves on their adjacent sides, and a rotating shaft 4 is installed in the groove. The end of the first rotating rod 2 that is rotatably connected to the first support plate 6 has a through hole and is inserted into the groove of the first support plate 6, with the rotating shaft 4 located in the through hole of the first rotating rod 2. Similarly, the end of the second rotating rod 3 that is rotatably connected to the second support plate 7 has a through hole and is inserted into the groove of the second support plate 7, with the rotating shaft 4 located in the through hole of the second rotating rod 3. This plug-in connection method provides a more secure and reliable installation compared to a side-rotating connection, and it also reduces the overall space occupied by the foldable wall-mounted anti-flow device, while also reducing its weight and facilitating installation and use.

[0042] In some examples, refer to Figure 5 The pull rod 5 consists of two plate-like structures connected by a pivot 4. The end of the first rotating rod 2 connected to the pull rod 5 is inserted into the pull rod 5 and is rotatably connected to the pull rod 5 via the pivot 4. The end of the second rotating rod 3 connected to the pull rod 5 is inserted into the pull rod 5 and is rotatably connected to the pull rod 5 via the pivot 4.

[0043] In some examples, refer to Figure 3 and Figure 4 The first rotating rod 2 has a mounting groove at one end connected to the pull rod 5, and the second rotating rod 3 has a protrusion at one end connected to the pull rod 5. The mounting groove and the protrusion are adapted to each other. Mounting holes for the rotating shaft 4 to pass through are provided in the mounting groove and the protrusion.

[0044] In some examples, the first rotating rod 2, the second rotating rod 3, the rotating shaft 4, the tie rod 5, the first support plate 6, and the second support plate 7 are all located on the side of the folded grout stop plate 1 away from the concrete, which plays a supporting role when pouring concrete and prevents grout leakage and flow caused by insufficient strength of the folded grout stop plate 1 itself.

[0045] The working process of the foldable diaphragm wall anti-bypass device provided by this utility model is as follows:

[0046] Before lowering the reinforcing cage, the trench section joint 8 is welded to the end of the reinforcing cage. Then, the second support plate 7 is welded to the side of the trench section joint 8 near the trench wall, so that the entire anti-flow device is placed perpendicular to the side wall of the trench section joint 8 and the trench wall. Pull the tie rod 5 upward, and the first rotating rod 2 and the second rotating rod 3 drive the first support plate 6 and the second support plate 7 to move towards the side closer to the tie rod 5, thereby folding the foldable grout stop plate 1. Then, when it is lowered to the designated elevation inside the trench along with the reinforcing cage and the trench section joint 8, the tie rod 5 is pressed downward, and the first rotating rod 2 and the second rotating rod 3 drive the first support plate 6 and the second support plate 7 to move away from the tie rod 5, opening the foldable grout stop plate 1. It is installed in place when the first support plate 6 presses against the side wall of the trench section joint 8. Finally, concrete is poured to achieve the purpose of stopping grout and preventing flow around the trench.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
