Description

technical field [0001] The invention relates to the technical field of flood control equipment, in particular to a foldable assembled self-stabilizing flood control and drainage facility. Background technique [0002] Flood control and water retaining facilities are one of the flood control equipment in flood control materials. Flood control and water retaining facilities are mainly flood control and water blocking equipment and facilities, mainly divided into common water blocking facilities such as water blocking walls, water retaining sandbags, water retaining boards, and water retaining doors. , facilities and means used to prevent flood disasters and site water accumulation during the flood season. However, in recent years, the duration of the flood season has lengthened after entering summer, and the number of severe weather such as typhoons and rainstorms has increased, and the level of rainstorms has also increased year by year (generally yellow and orange warning le...

Problems solved by technology

[0008] ①The flood control sandbag plays the role of flood control and water retention is sand, and the sand is filled in a fine-mesh bag (commonly made of cloth fabrics such as canvas or cotton linen), and it is slightly improper in use or improper in daily storage (for example, there are mice) chewing, etc.) can easily lead to damage to the fabric of the bag’s surface and sand leakage. Once the sand in the sandbag leaks excessively, it will easily cause the density and density of the sand to decrease, and eventually cause the porosity between the sand to increase, unable to resist the impact of incoming water and effectively intercept the sand. water;

[0009] ②Sandbags are generally filled with high-density sand, and a bag of sandbags is also relatively large, resulting in a bag of sandbags of high quality (heavier in weight), which is not convenient for manual handling (there are certain requirements for the physical fitness and fitness of the moving personnel). Even if there are small sandbags with small volume and light weight, although the load on the handling personnel is reduced, if a temporary waterproof project of a certain scale (long length and high height) is to be built, the total amount of sandbags required is also relatively large, which directly increases The number of times the user carries sandbags back and forth indirectly increases the load of the personnel on the other hand;

[0010] ③Flood control sandbags have the function of retaining water and intercepting water, but when building temporary waterproofing works, the gaps between sandbags are easy to seep (that is, the weak points of water interception), so generally multiple rows of sandbags are used. Deal with water seepage in the plugging gap to ensure the water interception effect. At the same time, if the incoming water is huge, the flood control sandbags should be stacked according to the maximum interception height of the incoming water, and the sandbags are arranged in a trapezoidal shape when stacked, and the water pressure of the uppermost layer is the smallest, so the number of stacked rows At least, the lowest layer has the highest water pressure, so the number of stacked rows is the largest. Such a waterproofing project will consume a lot of sandbags, manpower and material resources. If the number of stacked rows is not enough or the stacking height is not in place, it is easy to cause water seepage between sandbags, and incoming water will not pass through the top sandbags. , even if the water pressure is too large or the impact load of incoming water is large, it may easily cause the sandbag flood control project to collapse and be destroyed, which will cause certain economic losses and safety risks

[0014] ① The actual maximum height of the flood control baffle is limited by the height of the fixed notch reserved in its positioning and fixing components. If the height of the fixed notch is high, several water baffles can be inserted vertically to raise its The highest water-retaining height, and vice versa, but the reserved height of the conventional fixed notch is generally low, so the maximum water-retaining height of the water-retaining plate is also low, and the water-retaining capacity is limited

[0015] However, if the reserved height of the fixed notch is high, it will cause two problems: one is that it is difficult to deal with the waterproof and anti-leakage of the gaps between several water retaining plates inserted vertically, and there is no better treatment method for the time being; Replace some small water baffles with a large large water baffle with a high height and insert them into the reserved high fixed slots, it will be more difficult to insert into the slots, and the water baffle itself is made of metal, which may cause damage if the size is too large. The self-weight is too large, and manual operation is very inconvenient. It is also very inconvenient to manually take out the large water baffle after use. At the same time, the movable supports corresponding to the large water baffle may be specially customized, which consumes manpower, material resources and financial resources.

[0016] Therefore, when the water retaining plate works with a limited and low water retaining height and water retaining capacity, if the incoming water volume is huge or the water level rises rapidly, once the water retaining capacity is exceeded, it is very easy for the incoming water to submerge the water retaining plate and submerge behind it. area, at this time, the water retaining function of the water retaining plate is completely invalid

[0017] ②The water baffle can only be used in the parts or areas where the positioning and fixing components have been installed in advance. The location and scope of use are limited by the installation position of the positioning and fixing components. Flood control cannot be implemented in other places where there is a need but no positioning and fixing components are installed. The water retaining board is used to block water, and the water retaining board is generally placed on an ideal level ground. If the ground is uneven, the water retaining board cannot be effectively placed and used, which will cause water seepage from the ground depression, and the water retaining effect will be greatly reduced , it highlights that its use is limited, and it takes a certain amount of time to install the positioning and fixing components in advance, and the existing building structure must be modified. The preparation work is relatively large, and it consumes manpower, material resources and time.

[0018] ③Because the fender facilities are all assembled and spliced ​​by metal parts, each part of the metal parts will inevitably suffer from wear, loss or corrosion after long-term use. Purchasing certain spare parts and consumable parts for emergency maintenance and use will consume manpower, material resources and financial resources, and the later stage will cost more and be less economical. Less), it makes its cost of use higher, highlighting its low cost performance

[0024] ① The water blocking capacity of the water retaining gate of the quick-installed water retaining gate is also similar to that of the flood control water retaining plate. It is easy to cause the depth of accumulated water around the sluice plate to be too deep in a short period of time. When the depth of the accumulated water exceeds the upper surface of the sluice plate, the accumulated water will submerge the sluice plate and submerge the area behind it, and its function of retaining and intercepting water will be completely ineffective. At the same time, the difference from the flood control baffle is that the upper part of the baffle is provided with a lifting ring part and a supporting concave surface, which will cause the lifting ring to be retracted to the designated position even if it is not activated (such as Figure 7 to Figure 11 As shown), the top of the lifting ring will also have exposed protrusions relative to the upper surface of the gate plate, so that even if multiple water retaining gates are inserted into the reserved slots of the positioning component, the upper and lower gates will not be able to move due to the exposed protrusions of the lifting rings. Effectively closes the joint, leaving a seam through which water seeps, and ultimately fails to achieve an increase in the height of the water-retaining cut-off, thereby limiting its water-retaining and cut-off capabilities

[0027] However, whether it is the preparation of positioning or fixing components, it is determined that the location and scope of use of the sluice plate have certain limitations, and other places where there is a need but no positioning and fixing components are installed, the flood control sluice plate cannot be used to retain water , and the water retaining gate is generally placed on an ideal level ground for use. If the ground is uneven, the water retaining gate cannot be effectively placed and used, which will cause incoming water to seep from the ground depression, and the water retaining effect will be greatly reduced, which highlights its use. The limitations are relatively large, and it takes a certain amount of time to install the positioning and fixing components in advance, and the existing building structure must be modified. The preparation work is relatively large, and it consumes manpower, material resources and time

[0028] ③Because there are a lot of parts in the sluice gate facilities, and most of them are metal parts, which are assembled and spliced ​​by these parts, each part of the metal parts will inevitably have problems such as wear, loss or corrosion after long-term use. Regularly send special personnel to carry out maintenance and repairs, and at the same time, it is necessary to purchase additional spare parts and consumable parts for emergency repairs and use, which consumes manpower, material and financial resources, and the subsequent expenses are relatively large, and the economy is poor. , if the frequency of use of the sluice gate facility is not high (the number of times of use is small), it will make its use cost higher, highlighting its low cost performance

[0035] ① The water-retaining capacity and height of the water-absorbing expansion bag flood control and water-retaining facilities are limited by the height of its own plate body. It is easy to accumulate water too deep in a short period of time. When the depth of accumulated water exceeds the height of the plate body (water retaining capacity), the accumulated water will overflow from the top surface of the plate body and then submerge the area behind. At this time, the water retaining facility It will completely fail, and the water retaining facility only supports horizontal splicing and lengthening, and cannot achieve vertical heightening, so its water retaining height and capacity are not as good as the aforementioned flood control sandbags, flood control water retaining boards and quick-installed water retaining gate facilities. And when the horizontal splicing is long, the waterproof and water-retaining parts and seali
