Description

Technical Field

[0001] This utility model belongs to the field of urban flood control technology, and specifically relates to an urban flood control system. Background Technology

[0002] Urban flood control refers to the systematic work of preventing and responding to urban flooding disasters through a combination of engineering and non-engineering measures, ensuring the normal operation of the city and the safety of residents' lives and property. With the acceleration of urbanization, problems such as the increase in impervious areas and the lag in drainage systems have led to frequent urban flooding, making urban flood control an important project for people's livelihood and a key issue in urban governance.

[0003] Currently, the flood control measures used in cities are mostly structured in the following ways: Waterproof walls or dikes: Made of concrete, brick, or steel plates, they are built along the edges of river channels and low-lying areas, and are usually 0.5-2 meters high. They physically block river water from flowing back or surface runoff. This type of flood control structure occupies a lot of space. In urban core areas where land is scarce, flood walls will reduce the space for roads, green belts, etc., affecting the city's aesthetics and pedestrian passage. Threshold-style water barriers: These are often concrete or metal protrusions (10-30 cm high) installed at the entrances of underground parking garages, basement doors, and in front of street-front shops. They raise the ground level to prevent water from entering. However, they can only block shallow water (<30 cm). When the water depth exceeds the height of the barrier, they become completely ineffective. Furthermore, the gap between the barrier and the ground is prone to accumulating debris, reducing the seal and allowing water to seep in.

[0004] The above-mentioned flood prevention measures can only provide flood prevention for small areas or shallow layers, and the sealing effect cannot be guaranteed. In particular, when flood prevention is carried out at inlets and outlets or low-lying areas that require good sealing, the combined shielding process is easily affected by factors such as collision, pressure, and improper installation, resulting in leakage and poor flood prevention effect. Utility Model Content

[0005] The purpose of this invention is to provide an urban flood control system that uses high-strength waterproof fabric for highly stable and sealed connections, achieving a sealing effect while also resisting flood impacts.

[0006] The specific technical solution adopted by this utility model is as follows: An urban flood control system includes: Two pre-installed mounts; Waterproof tarpaulin and the cloth bag installed on the side of the waterproof tarpaulin; A first mounting cylinder and a second mounting cylinder, both having a C-shaped cross-section, the second mounting cylinder being fixedly connected to a pre-mounting base, and the cloth bag being respectively disposed inside the first mounting cylinder and the second mounting cylinder; A first inflation pressure assembly and a second inflation pressure assembly are provided, wherein the first inflation pressure assembly is disposed inside the bag and the second inflation pressure assembly is disposed outside the waterproof cloth; The reinforced support assembly is detachably connected between two pre-installed mounts.

Detailed Implementation

[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model. Example

[0021] like Figures 1-8 As shown, an urban flood control system includes: Two pre-installation seats 1; the side walls of the pre-installation seats 1 have several reserved holes 18. In the early stages of flood prevention work, the pre-installation seats 1 should be connected vertically to the ground on the entrance door frame or column using expansion bolts, and waterproof sealing treatment should be performed between the pre-installation seats 1 and the wall.

[0022] Waterproof fabric 2 and a cloth bag 3 installed on the side of the waterproof fabric 2; the cloth bag 3 is made of waterproof material and the diameter of the cloth bag 3 is not less than 60mm; The first mounting cylinder 4 and the second mounting cylinder 5 have C-shaped cross sections. The distance between the openings on the first mounting cylinder 4 and the second mounting cylinder 5 is not less than 30mm, which facilitates the placement and removal of the cloth bag 3. The second mounting cylinder 5 is fixedly connected to the pre-mounting base 1. The second mounting cylinder 5 is distributed at right angles, and the cloth bag 3 is respectively placed in the first mounting cylinder 4 and the second mounting cylinder 5. The first inflation pressure component is located inside the cloth bag 3, and the second inflation pressure component is located outside the waterproof cloth 2. In the first inflation pressure component, the pressure medium can be high-pressure gas or high-pressure water.

[0023] The reinforced support assembly is detachably connected between the two pre-installed mounts 1.

[0024] like Figure 1 As shown, there are several first mounting cylinders 4, which are installed in sections according to the length of the flood control facility location. Furthermore, the end faces of the first mounting cylinders 4 can adopt a concave-convex fit structure to increase sealing during connection and prevent water seepage.

[0025] like Figure 10 As shown, when installing the first mounting cylinder 4, it needs to be buried below the ground surface, and the opening of the first mounting cylinder 4 is flush with the ground surface. The corner of the second mounting cylinder 5 also needs to be buried below the ground surface and aligned with the first mounting cylinder 4, so that the cloth bag 3 can be inserted from the opening.

[0026] like Figure 1 and Figure 2 As shown, the first inflation pressure assembly includes a first pressure hose 6, which penetrates the cloth bag 3 in its uninflated state. A first air valve 7 is fixedly connected to the end face of the first pressure hose 6. The first air valve 7 is a pressure relief valve, which facilitates the control of the pressure inside the first pressure hose 6.

[0027] The other end of the first pressure hose 6 is fixedly connected to a tee pipe 23, and the top end of the tee pipe 23 is fixedly connected to a pressure gauge 24. A check valve 25 is installed on the side wall of the tee pipe 23, and the other end of the check valve 25 is fixedly connected to a diverter pipe 26. The diverter pipe 26 is connected to the second air valve 15 on the second pressure hose 14, and the other end of the diverter pipe 26 can be connected to an external air or water supply device. The pressure gauge 25 can monitor the internal pressure value of the pipeline in real time.

[0028] like Figure 3 As shown, the second inflation pressure assembly includes multiple second pressure hoses 14, which surround the first mounting cylinder 4. A first pressure hose 6 is located inside the first mounting cylinder 4 and presses against the second pressure hoses 14. A second air valve 15 is fixedly connected to one end of each second pressure hose 14. The first pressure hose 6 and the second pressure hose 14 can withstand pressures of 0.3 MPa or higher.

[0029] In some embodiments, the second pressure hose 14 can serve as an auxiliary support structure to support the waterproof cloth 2. In actual flood control applications, users can choose whether to use it according to their needs.

[0030] The inner diameter of the first mounting cylinder 4 and the second mounting cylinder 5 is 5 mm smaller than the maximum diameter of the first pressure hose 6 and the second pressure hose 14 after expansion. For example, if the inner diameter of the first mounting cylinder 4 and the second mounting cylinder 5 is 60 mm, then the maximum diameter of the first pressure hose 6 and the second pressure hose 14 after expansion is 65 mm. This unique interlocking structure, featuring a large expandable inner diameter of the first pressure hose 6 and smaller inner diameters of the first mounting cylinder 4 and the second mounting cylinder 5, allows for expansion when high-pressure water or gas is introduced into the first pressure hose 6. Before reaching its maximum expansion, the first pressure hose 6 is constrained by the dimensions of the first and second mounting cylinders 4 and 5. Under its own high pressure, the outer shell of the first pressure hose 6 continues to expand and be pressed against the inner walls of the first and second mounting cylinders 4 and 5. The waterproof fabric 2, encased in the middle, is then firmly compressed and sealed by this internal and external pressure difference, achieving a leak-proof design within the first and second mounting cylinders 4 and 5.

[0031] like Figure 1 and Figure 6 As shown, the reinforcing support assembly includes a rope 8, with a hook 9 fixedly connected to one end of the rope 8. Several hanging rings 10 are movably connected to the opposite side wall of the pre-installation base 1. The hook 9 and the hanging rings 10 are adapted to each other. A tensioning component is provided at the other end of the rope 8.

[0032] The tensioning assembly includes a rectangular ring 11, with screws 12 threadedly connected to the left and right side walls of the ring 11. Adjusting hooks 13 are fixedly connected to the ends of the screws 12. The left adjusting hook 13 is connected to the rope 8, and the right adjusting hook 13 is connected to the hanging ring 10 on the other side. The locking assembly is similar to the existing tensioner structure, is a mature existing structure, and is not the focus of this solution; therefore, it will not be described in detail here.

[0033] The component includes several tensioning components, one of which has a rope 8 that can pass through the interior of the waterproof cloth 2, positioning it inside the waterproof cloth 2 near the top, thus forming an integral structure with the waterproof cloth 2 for flexibility and convenience during subsequent installation.

[0034] The multi-layered structure, consisting of a waterproof fabric 2 on the water-facing side and a rope 8 on the back side, combines the advantages of the rope 8 (high tensile strength) and the waterproof fabric 2 (strong sealing performance) to create a more robust guarantee for the waterproof fabric 2's waterproofing and flood prevention. This enhances the overall structural performance of the waterproof fabric 2 to withstand the compressive force of more than 5 tons of accumulated water.

[0035] like Figure 1 and Figure 2As shown, the waterproof fabric 2 has several through holes 16 near the top of its side wall, and cable ties 17 connect the uppermost rope 8 to the through holes 16. After the waterproof fabric 2 is installed, to prevent deformation or wrinkles at the top, the top of the waterproof fabric 2 can be fixed to the uppermost rope 8 using the cable ties 17, further enhancing the compressive strength of the waterproof fabric 2. Furthermore, metal rings are installed inside each through hole 16 to prevent concentrated stress on the through holes 16, thus avoiding tearing or damage to the waterproof fabric 2. Example

[0036] An installation process for an urban flood control system, the installation process comprising the following steps: S1: First, fix the pre-installation seat 1 to the flood control inlet and outlet wall position through the reserved hole 18 using expansion bolts. The pre-installation seats 1 on both sides need to be installed symmetrically. S2: Next, insert the first pressure hose 6 into the cloth bag 3 so that the first pressure hose 6 passes through the cloth bag 3. Then, fold the second pressure hose 14 into a ring and place it inside the first mounting cylinder 4 so that the second air valve 15 is exposed on the outside. S3: Then the waterproof cloth 2 passes through the ring formed by the second pressure hose 14, and the cloth bag 3 together with the first pressure hose 6 is inserted into the first mounting cylinder 4 and the second mounting cylinder 5. S4: Then connect the first air valve 7 and the second air valve 15 to external compressed gas for air injection, so that the first pressure hose 6 and the second pressure hose 14 expand and bulge, tightly fitting the cloth bag 3 inside the first mounting cylinder 4 and the second mounting cylinder 5. At this time, fold the second pressure hose 14 into a triangular structure. S5: Then, the rope 8 is hung on the left hanging ring 10 via the hook 9, and the right adjusting hook 13 is hung on the right hanging ring 10. The rope 8 is tightened by rotating the adjusting hook 13, and multiple ropes 8 are installed in sequence. S6: Then pass the cable tie 17 through the through hole 16 and tie it to the uppermost rope 8, so that the waterproof cloth 2 forms a sealed shielding structure between the pre-installation seat 1 and the first installation cylinder 4. Example

[0037] Based on Example 1, this example specifically illustrates the application of the first mounting cylinder 4: Cut a groove of the same size and shape into the ground at the entrance and exit for the first mounting cylinder 4, and pour cement into the gap for waterproofing. The first mounting cylinder 4 can be left in the ground and flush with the ground so as not to affect the normal passage of vehicles. Cover the first mounting cylinder 4 with a cover plate to block the opening and prevent dust accumulation for easy passage. The cover plate can be removed when in use. Example

[0038] Based on Example 3, this example specifically illustrates another application of the first mounting cylinder 4: like Figure 7 and Figure 8 As shown, it also includes a support base 19, which has a U-shaped structure. The first mounting cylinder 4 is adapted to the support base 19. Several studs 20 are fixedly connected to the side wall of the first mounting cylinder 4. Several grooves 21 are opened on the top end face of the support base 19. The studs 20 are adapted to the grooves 21. Nuts 22 are threadedly connected to the side wall of the studs 20.

[0039] A groove of the same size and shape is cut into the ground at the entrance. A support base 19 is placed in the groove, and concrete is poured to fill the gap between the support base 19 and the groove. When not in use, a cover plate is used to cover the support base 19 for sealing. When in use, the cover plate is removed, and a suitable number of first mounting cylinders 4 with studs 20 are selected and placed in the support base 19 so that the studs 20 correspond to the grooves 21 and are engaged. Then, the nuts 22 are tightened to fix it. A sealing strip is provided inside the support base 19 to increase the sealing between the support base 19 and the first mounting cylinders 4.

[0040] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
