Description

Technical Field

[0001] The invention relates to the field of flood control devices, in particular to a flood control and water retaining engineering structure with a composite floating body. Background Art

[0002] When torrential rains suddenly hit cities or villages, it is easy to cause serious waterlogging in low-lying areas and their surrounding areas. In serious cases, the water flows back into the houses and areas through various doorways such as subway doorways, underground parking lot entrances and exits, roads in front of the ground floor of civil buildings, entrances and exits of underground construction sites or their surroundings, causing numerous rainstorm disasters. At present, the temporary flood prevention measures commonly used by the block management office include preparing waterproof sandbags, which are piled up next to various doorways for a long time, affecting the appearance of the block. There are still many shortcomings in the applied flood control water retaining boards. First of all, they need to be temporarily installed manually. In the case of sudden heavy rain or sudden accumulation of water in low-lying areas, there is often no time to install them. Secondly, the existing flood control water retaining boards are mostly made of aluminum alloy or plastic. In the event of sudden heavy rain, due to insufficient deformation stiffness or inadequate emergency fixing measures at the ends, the accumulated water often breaks through or rushes through the flood control water retaining boards. Therefore, it is of great practical significance to develop a flood control water retaining device with specific automatic lifting characteristics, which can automatically respond and rise when heavy rain comes to play a role in flood control and water retaining in time, and can also resist the greater impact of heavy rain and accumulated water.

DETAILED DESCRIPTION

[0026] Specific implementation method 1: refer to Figures 1 to 5 The present embodiment is described. The present embodiment provides a flood control and water retaining engineering structure with a composite floating body, which is characterized in that: the composite device includes a floating body 1 and a preset groove 2, the preset groove 2 is arranged on the top of a waterproof doorway 4 where a flood control and water retaining device needs to be arranged, the floating body 1 is arranged in the preset groove 2, the outer side of the preset groove 2 is processed with a guide groove 8, the guide groove 8 is covered with a rainwater grate 3, and the bottom of the guide groove 8 is evenly distributed with a plurality of conduits 5 along the contour direction of the guide groove 8, one end of each conduit 5 is connected to the guide groove 8, and the other end of each conduit 5 is connected to the preset groove 2.

[0027] The present embodiment provides a floating flood control and water retaining composite device, which controls the rise of the buoyancy body by facilitating the buoyancy generated by rainstorm water accumulation, effectively blocks the road or square in front of the building that needs waterproofing, and effectively prevents rainstorm water from flowing back into the low-lying area and causing property losses. In this solution, the buoyancy body will be hidden in the preset groove in non-rainstorm weather, and the top of the buoyancy body is coplanar with the ground pavement layer on the upper surface of the preset groove, which is convenient for people to walk normally. A preset groove 2 is arranged outside the waterproof doorway 4 where the flood control device needs to be arranged, and a floating body 1 is placed inside. When rainwater overflows to the plane in front of the waterproof doorway 4, the rainwater flows through the rainwater grate 3 and the guide groove 8 below it, and overflows into the bottom of the reserved groove 2 through the conduit 5. When the buoyancy is greater than the gravity of the floating body 1, the floating body 1 is continuously injected with rainwater. When the buoyancy is greater than the gravity of the floating body, the water retaining floating body gradually rises automatically. After reaching the designed elevation, it stops floating under the reaction force of the anti-floating flange plate and realizes the closure of the internal enclosure edge. In the present application, the top surface of the rainwater grate 3 is evenly distributed with a number of small round through holes, which are used to prevent stones or large clods of earth from entering the guide groove 8.

[0028] Specific implementation method 2: refer to Figures 1 to 5This embodiment is described. This embodiment further limits the preset groove 2 described in the specific embodiment 1. In this embodiment, the preset groove 2 is closed and arranged along the contour of the waterproof doorway 4 where the flood control and water retaining device is required to be arranged. Other components and connection methods are the same as those in the specific embodiment 1.

[0029] Such an arrangement can improve the enclosure effect after the floating body 1 rises, making it easier to completely surround the door of the waterproof doorway 4 of the building where flood control equipment is required, ensuring the waterproof effect and ensuring that the waterproof doorway 4 can be closed when the floating body 1 in the preset groove 2 rises.

[0030] Specific implementation method three: refer to Figures 1 to 5 This embodiment is described as further limiting the conduit 5 described in the second embodiment. In this embodiment, the plurality of conduits 5 are inserted obliquely into the waterproof pier, and the inclination angle of each conduit 5 is 60°-80°. Other components and connection methods are the same as those in the second embodiment.

[0031] In this arrangement, each catheter 5 is inserted obliquely into the preset groove to avoid blockage when the catheter 5 is draining, thereby increasing the smoothness of the drainage. The catheter 5 can also be arranged in a zigzag shape, but an elbow connection is required. This arrangement is generally used when the catheter diameter is relatively thick, and there is no need to worry about blockage. At the same time, this arrangement is simpler when setting up, and there is no need to adjust and calculate the inclination angle of the catheter, saving the arrangement cost.

[0032] Specific implementation method 4: refer to Figures 1 to 5 This embodiment is described. This embodiment further limits the conduit 5 described in the fourth embodiment. In this embodiment, an overflow guide 7 is processed at the connection between each conduit 5 and the preset groove 2, and a filter screen is installed at the outlet of each overflow guide 7. Other components and connection methods are the same as those of the third embodiment.

[0033] With such an arrangement, the filter screen can effectively block debris in the accumulated water, preventing the debris from entering the preset groove and accumulating at the bottom of the groove, hindering the buoyancy body from descending, or preventing it from descending to the initial position. At the same time, the overflow outlet 7 is arranged as close as possible to the bottom of the preset groove, so that the accumulated water can be directly drained to the bottom of the groove.

A top embedded flange 19 is provided at the top of the inner wall of the preset groove 2. The top embedded flange 19 and the inner wall of the preset groove 2 are integrally cast with concrete or formed by mortar masonry. Other components and connection methods are the same as those of the fourth embodiment.

[0048] The present invention has been disclosed as above with preferred implementation cases, but it is not intended to limit the present invention.

[0049] How it works

[0050] The present invention is mainly used in heavy rain weather. In heavy rain weather, rainwater will enter the guide groove 8 along the rainwater grate 3, and the rainwater will enter the preset groove 2 through the multiple conduits 5 arranged at the bottom of the guide groove 8 and be stored in the preset groove 2. As the amount of water in the preset groove 2 increases, the buoyancy will gradually become greater than the gravity of the floating body 1. The floating body 1 will automatically rise as the rainwater continues to be injected. After reaching the designed elevation, it will stop floating under the reaction force of the anti-floating flange plate and realize the closure of the internal enclosure edge. The spacer-type raised flange plate 12 located on the outside of the floating body 1 contacts the top embedded flange 19 of the preset groove 2 for anti-floating effect. The outer edge of the top embedded flange 19 is coated with lubricating grease to ensure that the resistance of the buoyancy body 1 during the floating process is reduced. The spacer groove 13 is used for overflow water injection of the overflow guide port 7. The inner anti-floating flange plate 14 in the middle is a three-sided closed structure, which contacts the top embedded flange 19 of the preset groove 2 for anti-floating and water-tightening effects. After the rainstorm stops, the accumulated water in the preset groove is gradually discharged during the sinking process of the floating body by evenly distributing additional heavy weights on the floating body. For a larger floating body, if conditions permit, the rainwater grate 3 can also be opened, and the accumulated water in the diversion groove 8 and the preset groove 2 can be pumped out by a pump, so as to realize the sinking action of the floating body 1. Under the influence of the back-pumped water flow, the debris that enters the groove driven by the water flow can also be pumped out together with the debris left in the conduit 5 by the pumping method, which is beneficial to the diversion effect of the conduit 5 when the device is used repeatedly and efficiently.

[0051] Example:

[0052] The design size and shell wall thickness of the specific floating body 1 of the present invention when in use can be determined by design calculation according to the design flood control and water retaining height requirements. The following takes the middle outer spacer anti-floating flange plate assembly, the middle inner anti-floating flange plate 14, the inner web 16 and the outer web 17 made of fiber-reinforced ultra-high performance concrete, with a flood control and water retaining height of 500mm as an example to introduce the implementation plan of the minimum design height limit of the lower pontoon under different shell wall thicknesses and floating body widths.

[0053] The implementation plan is as follows:

[0054] (1) The wall thickness of the floating body 1 is 20 mm, the width of the floating body 1 is 350 mm, and the height of the lower pontoon is not less than 730 mm.

[0055] (2) The wall thickness of the floating body 1 is 20 mm, the width of the floating body 1 is 400 mm, and the height of the lower pontoon is not less than 630 mm

[0056] (3) The wall thickness of the floating body 1 is 20 mm, the width of the floating body 1 is 450 mm, and the height of the lower pontoon is not less than 570 mm

[0057] (4) The wall thickness of the floating body 1 is 10 mm, the width of the floating body 1 is 300 mm, and the height of the lower pontoon is not less than 460 mm

[0058] (5) The wall thickness of the floating body 1 is 10 mm, the width of the floating body 1 is 350 mm, and the height of the lower pontoon is not less than 420 mm.

[0059] (6) The wall thickness of the floating body 1 is 10 mm, the width of the floating body 1 is 400 mm, and the height of the lower pontoon is not less than 380 mm

[0060] (7) The wall thickness of the floating body 1 is 10 mm, the width of the floating body 1 is 450 mm, and the height of the lower pontoon is not less than 360 mm.

[0061] In the above seven embodiments, the height of the upper flood control part is greater than 500mm, which can achieve the effect of water blocking and flood control in a simulated rainstorm weather environment. At the same time, the wall thickness and width setting of the floating body 1 can also withstand the impact when water accumulates outside the buoyancy body 1, and within 3-6 hours of the accumulation of water, the buoyancy body 1 does not deform and can be used repeatedly.
