Description

Technical Field

[0001] This utility model relates to the field of flood control wall technology, specifically to a prefabricated flood control wall. Background Technology

[0002] A flood control wall is a concrete or masonry water-retaining structure used to ensure flood control safety in towns and important industrial and mining enterprises, along rivers, and coastal areas (some seawalls), or for other special requirements.

[0003] To ensure normal traffic flow in urban areas and meet normal flood control needs, some sections of the floodwall are prefabricated (typically located at major traffic arteries) to allow for disassembly and reinstallation, based on the actual flood season. This ensures normal traffic flow during normal times and provides flood control during floods. Existing prefabricated floodwalls generally fall into two categories: one uses sandbags for interception, which meets flood control needs when water levels are low, but involves significant labor and is difficult to dismantle; the other uses a precast reinforced concrete frame, with concrete poured inside to form reinforced concrete slabs for interception. This method meets stable flood control needs, but dismantling requires breaking up the concrete, and the concrete structure cannot be reused, increasing operating costs.

[0004] Currently, a utility model patent with announcement number CN219637799U discloses a prefabricated assembled flood control wall. This prefabricated assembly allows the installation of flood control wall components to be carried out in advance or simultaneously with site leveling and excavation, thereby significantly shortening the construction period and solving the technical problem of long construction cycles associated with existing cast-in-place technologies. The wall includes a prefabricated foundation, a prefabricated flood control wall body vertically positioned on the top surface of the prefabricated foundation, and prefabricated buttress columns perpendicularly arranged to both the prefabricated foundation and the prefabricated flood control wall body. It offers advantages such as fast construction speed, high construction quality, and effective reduction of on-site construction safety hazards.

[0005] In existing technologies, reinforced concrete flood walls, after being fixed with concrete through pouring, can effectively block floods, but are inconvenient to dismantle after the flood recedes. While the aforementioned technical solutions prefabricate most of the flood wall structure, concrete pouring is still required for connection during actual use. This only ensures the ease of installation, not the ease of dismantling. Therefore, there is an urgent need for a flood wall that is easy to install and dismantle to solve these problems. Utility Model Content

[0006] Based on the above description, this utility model provides a prefabricated flood control wall to solve the problem that the existing prefabricated flood control wall structure is inconvenient to dismantle after the flood recedes.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a prefabricated flood control wall, including an assembly plate, two fixed walls set on the ground, and a sinking groove opened on the ground, the sinking groove being located between the two fixed walls on opposite sides; The assembly plate is provided with a flood control component, and the bottom of the flood control component is provided with a limiting module. The limiting module includes a docking component located in the sinking groove and a sinking block located at the bottom of the flood control component. The sinking block is inserted into the sinking groove, and a locking component is provided between the docking part and the assembly plate; The flood control component is provided with an installation module on its outer side. The flood control component is slidably connected between two fixed walls on opposite sides through the installation module. The installation module is wrapped with a filler that serves as a sealant. A support module is detachably connected between the assembly plate and the flood control component.

[0008] The above technical solution allows the flood control component to be installed in the sinking trough through the cooperation of the connecting part and the sinking block, so that the flood control component can block the space between the two fixed walls on opposite sides; the support module can provide auxiliary support for the flood control component, so that it can play a more stable role in blocking floods.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the docking component includes several ground anchors buried underground, with a limiting steel at the top of the anchor and the limiting steel located in the sinking trench. The sinking trough is also equipped with several limiting cylinders, which are arranged alternately with the limiting steel.

[0011] The above technical solution uses ground-mounted reinforcing bars to fix the limiting steel, enabling it to play a stable limiting role.

[0012] Furthermore, the bottom of the sinking block is provided with a limiting groove for the insertion of a limiting steel, the bottom of the sinking block is provided with a limiting groove for the insertion of a limiting cylinder, and the top of the limiting cylinder is provided with a cross-shaped groove. A flower-shaped block is inserted into and slidably connected within the cross-shaped groove. A threaded rod is provided on the top of the flower-shaped block, and a nut is threadedly connected to the outside of the threaded rod.

[0013] The above technical solution, through the combination of the limiting groove and the limiting steel, can limit the sinking block; through the combination of the cross-shaped groove and the flower-shaped block, the position of the threaded rod can be limited, and then the nut can achieve a stable fastening effect.

[0014] Furthermore, the top of the assembly plate is provided with a through hole for the threaded rod to pass through, and the through hole corresponds one-to-one with the limiting cylinder. The cross-shaped groove is connected to the interior of the corresponding through hole, and the top of the limiting cylinder abuts against the bottom of the assembly plate. The nut abuts against the top of the assembly plate, and two auxiliary cylinders are provided in the sinking groove, which are symmetrically distributed from left to right.

[0015] The above technical solution enables the engagement of the threaded rod and nut to lock the position of the assembly plate.

[0016] Furthermore, the flood control component includes a flood barrier plate located on top of the assembly plate, the flood barrier plate having two lifting rings and several blocking strips on one side of the flood barrier plate that prevents flooding; The blocking strips are arranged in an alternating pattern on the flood barrier plate. The blocking strips are arc-shaped, with the concave side of the blocking strip facing the side closest to the ground.

[0017] The above technical solution enables the flood barrier to block floodwaters; under the restriction of the barrier strip, it can block the upward-rushing floodwaters and reduce their impact force.

[0018] Furthermore, the installation module includes two side sliders respectively located on both sides of the flood barrier. Each of the two fixed walls has a side sliding groove on its opposite side. The top of the side sliding groove is open, and the side sliding groove allows the side sliders on the same side to be inserted and slide.

[0019] The above technical solution allows the flood barrier to be slidably connected between two fixed walls on opposite sides through the cooperation of the side slider and the side sliding groove.

[0020] Furthermore, the top of the fixed wall is detachably connected to a top plate, and fastening bolts are installed on the top plate. The top of the side slider is provided with an internal thread groove for threaded connection of the fastening bolts.

[0021] The above technical solution allows for the limitation of the top of the side slider by using the combination of the top plate and the fastening bolts.

[0022] Furthermore, the filler includes two water-stop pads respectively bonded to the outside of the two side sliders. The inside of the water-stop pads is hollow. The water-stop pads are inflated and expanded, and air nozzles are provided on the water-stop pads.

[0023] The above technical solution allows the water-stop pad to fill the gap between the side slider and the side groove, thus enhancing the sealing performance.

[0024] Furthermore, the support module includes a folding plate hinged to the mounting plate, the folding plate being rotatable toward a side closer to or further away from the flood barrier. Two diagonal braces are detachably connected between the top of the folding plate and the outer side of the flood barrier.

[0025] The above technical solution uses diagonal braces to provide auxiliary support for the flood barrier.

[0026] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: 1. The modular design allows the prefabricated flood wall to be divided into several modules, facilitating transportation and disassembly. By creating a sinking channel on the ground and pre-setting a connecting structure within the sinking channel, the flood control components can be directly installed in the sinking channel when needed. This design also limits the vertical and horizontal movement of the flood control components, ensuring they remain stable and effectively intercept floodwaters. 2. The blocking strip can block the impact of water flow and prevent water flow from passing over the flood control wall, thus improving the flood control and water blocking effect. The water-stop pad can effectively seal the connection between the flood discharge component and the fixed wall, preventing a large amount of water from entering the structure and preventing water from flowing to the other side of the flood control component through the connection, so that it can meet the needs of multiple reuses.
