Anti-floating buffering flexible pool for underground water with high level

Abstract

The invention discloses an anti-floating buffering flexible pool for a high underground water level. According to the invention, the anti-floating problem of the flexible pool body when the underground water level is relatively high is effectively solved through the interlayer structure. The interlayer material can automatically expand when the underground water level rises to form supporting force to resist the jacking effect of water buoyancy on the pond bottom, so that the pond body is prevented from floating upwards. Therefore, the application limitation of a traditional flexible pool body in areas with the high underground water level is broken through, the application range of the flexible pool body is widened, and the flexible pool body can be applied to more areas, especially occasions with poor foundations, the high underground water level and the high requirement for the water storage capacity. The anti-floating buffering flexible pool can effectively solve the problems in coastal areas, areas with rich underground water resources, urban underground spaces and the like, and a safe and reliable water storage solution is provided for the areas.

Description

Technical Field

[0001] The invention belongs to the technical field of underground flexible pools, and in particular relates to an anti-floating buffer flexible pool for use at a relatively high underground water level. Background Art

[0002] Flexible pools are mainly used in areas with poor foundations and low water levels. Compared with rigid pools, they require less investment and shorter construction periods. The disadvantage is that the depth of the pool bottom is limited by the anti-floating water level and must not be higher than the pool bottom, otherwise the anti-floating will fail when the pool is empty. Therefore, if flexible pools are used in areas with high anti-floating water levels, it is often necessary to build a groundwater drainage system.

[0003] Purpose: When the groundwater level is higher than the bottom of the flexible pool, the only options are to reduce the depth of the flexible pool, reduce the capacity, or use a groundwater drainage system. When the groundwater level is not high, the capacity requirement is high, and the floor area is limited, the use of a pumping and drainage system is the only solution. However, the layout of the pumping and drainage system is cumbersome, and the management and operation costs are high. The addition of a folded interlayer pool body can solve the anti-floating problem of the flexible pool while controlling the cost. Summary of the invention

[0004] The object of the present invention is to provide an anti-floating buffer flexible pool for use at a relatively high groundwater level in order to solve the above-mentioned problems.

[0005] The technical solution adopted by the present invention is as follows: a flexible anti-floating buffer pool for use with a high groundwater level, characterized in that it includes a double-layer flexible water pool, an anti-floating buffer layer is arranged below the double-layer flexible water pool, a plurality of pressure relief holes are opened at the bottom of the double-layer flexible water pool, an interlayer is arranged inside the double-layer flexible water pool above the anti-floating buffer layer, and a pebble layer is arranged at the bottom of the double-layer flexible water pool.

[0006] In a preferred embodiment, the interlayer is made of folded meshed polyetherethylene PVC cloth.

[0007] In a preferred embodiment, the spacing between the pressure relief holes is 2 to 3 m.

[0008] In a preferred embodiment, a sand and gravel filter layer is provided below the pressure relief hole to prevent mud and sand from entering and clogging the hole.

[0009] In a preferred embodiment, the interlayer capacity should be able to accommodate the amount of water whose anti-floating water level exceeds the water volume of the pool bottom, so as to ensure that the pool body can effectively resist floating even when the pool is empty.

[0010] In a preferred embodiment, the inner water storage layer material of the double-layer flexible water pool has good waterproof performance, and the outer interlayer material should have good flexibility, strength and filtering performance.

[0011] In a preferred embodiment, a method for using an anti-floating buffer flexible pool with a high groundwater level is characterized in that the method comprises the following steps:

[0012] S1: Empty pool state: When the groundwater level is higher than the pool bottom and there is no water in the pool, groundwater enters the interlayer through the filter layer and pressure relief holes.

[0013] S2: Interlayer expansion: As groundwater enters, the water level in the interlayer gradually rises, and the interlayer material expands, forming a certain supporting force to resist the supporting force of groundwater on the bottom of the pool.

[0014] S3: Pressure balance: When the water level in the interlayer reaches a certain level, the supporting force of the interlayer and the supporting force of the groundwater are balanced, and the pool body remains stable and will not float.

[0015] S4: Water storage state: When water begins to enter the pool, the water exerts downward pressure on the interlayer, causing the interlayer to gradually fold and flatten.

[0016] S5: Capacity recovery: As the interlayer is folded, the water storage space of the pool is restored without affecting the water storage capacity of the pool.

[0017] S6: Continuous stability: During the water storage process in the pool, the interlayer always remains in a folded state, the pool body is stable, and no special person is required to monitor and adjust it.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] 1. In the present invention, the anti-floating problem of the flexible pool body when the groundwater level is high is effectively solved by the sandwich structure. The sandwich material can automatically expand when the groundwater level rises to form a supporting force to resist the buoyancy of the water on the bottom of the pool, thereby preventing the pool body from floating up. This design breaks through the application limitations of traditional flexible pool bodies in areas with high groundwater levels, broadens the scope of use of flexible pool bodies, and enables them to be used in more areas, especially in places with poor foundations, high groundwater levels and high requirements for water storage capacity. Coastal areas, areas with rich groundwater resources, and urban underground spaces, etc., these areas often face problems such as high groundwater levels and unstable foundations, and traditional flexible pool bodies are difficult to meet the needs. The anti-floating buffer flexible pool can effectively solve these problems and provide a safe and reliable water storage solution for these areas.

[0020] 2. In the present invention, the flexible pool body is more convenient and quick during the construction process, with a short construction period, and there is no need to build a complex groundwater drainage system, thereby reducing the project cost. In addition, the use of interlayer materials also makes the pool body lighter and easier to transport and install. In terms of operation and management, since the interlayer can automatically adjust the pressure, there is no need for special personnel to monitor and adjust, which further reduces the management cost. These factors work together to make the anti-floating buffer flexible pool have higher economic benefits. In occasions such as temporary water supply and temporary sewage treatment, the flexible pool body can be used to quickly build water storage facilities to meet temporary needs while reducing construction costs and management costs. In addition, in the development of urban underground space, the flexible pool body can save underground space, improve space utilization, and reduce construction costs. Therefore, the flexible pool body has high economic benefits in many fields and has broad application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] Reference Figure 1-3 ,

[0027] A flexible anti-floating buffer pool for use with a high groundwater level comprises a double-layer flexible water pool 1, an anti-floating buffer layer 2 is arranged below the double-layer flexible water pool 1, a plurality of pressure relief holes 3 are opened at the bottom of the double-layer flexible water pool 1, and an interlayer 4 is arranged above the anti-floating buffer layer 2 inside the double-layer flexible water pool 1.

[0028] The bottom layer of the double-layer flexible water pool 1 is provided with a pebble layer 5, the thickness of which is 200 mm, which can press the bottom layer before the groundwater enters the interlayer, play a partial anti-floating role, and also serve as a filter.

[0029] The interlayer 4 is made of folded mesh polyetherethylene PVC cloth.

[0030] The spacing between the pressure relief holes 3 is 2 to 3 m.

[0031] A sand and gravel filter layer is arranged below the pressure relief hole 3 to prevent mud and sand from entering and clogging the hole.

[0032] The capacity of interlayer 4 should be able to accommodate the amount of water whose anti-floating water level exceeds the water volume of the pool bottom, so as to ensure that the pool body can effectively resist floating even when it is empty.

[0033] The inner water storage layer material of the double-layer flexible water pool 1 has good waterproof performance, and the outer interlayer material should have good flexibility, strength and filtering performance.

[0034] A method for using an anti-floating buffer flexible pool for a high groundwater level: the method comprises the following steps:

[0035] S1: Empty pool state When the groundwater level is higher than the pool bottom and there is no water in the pool, groundwater will enter the interlayer through the sand and gravel filter layer under the pool body. At this time, the pressure relief hole in the interlayer has not been opened, the water level in the interlayer gradually rises, and the interlayer material begins to expand. The expansion of the interlayer can not only effectively resist the top support of groundwater, but also prevent sediment from entering the pressure relief hole, ensuring the smooth flow of the pressure relief hole.

[0036] S2: Interlayer expansion As groundwater continues to enter the interlayer, the water level in the interlayer continues to rise, and the interlayer material expands further. At this time, the supporting force of the interlayer gradually increases, which can effectively balance the supporting force of the groundwater. The flexibility and strength of the interlayer material ensure the stability of the pool body in the empty pool state and prevent the pool body from floating.

[0037] S3: Pressure balance When the water level in the interlayer reaches a certain level, the supporting force of the interlayer and the supporting force of the groundwater are balanced, and the pool body remains stable. At this time, the pressure relief holes in the interlayer begin to open automatically to release the excess water pressure in the interlayer and prevent the interlayer from over-expanding. The automatic opening of the pressure relief holes ensures the safety of the pool body and avoids damage to the pool body due to excessive expansion.

[0038] S4: Water storage state When the pool starts to fill with water, the water exerts downward pressure on the interlayer, causing it to gradually fold and flatten. The folding of the interlayer can not only restore the water storage space of the pool, but also prevent the interlayer from over-expanding and affecting the water storage capacity of the pool. The folding of the interlayer ensures the stability of the pool in the water storage state and ensures the water storage function of the pool.

[0039] S5: Capacity recovery As the interlayer folds, the water storage space of the pool body gradually recovers. At this time, the pool body can continue to take in water until it reaches the designed water level. The folding of the interlayer ensures the stability of the pool body in the water storage state and ensures that the water storage capacity of the pool body is not affected.

[0040] S6: Continuous stability: During the water storage process, the interlayer always remains in a folded state. The folding of the interlayer ensures the stability of the pool body during water storage, without the need for dedicated personnel to monitor and adjust. At the same time, the folding of the interlayer also ensures the safety of the pool body and avoids damage to the pool body due to excessive expansion.

[0041] In the present invention, the anti-floating problem of the flexible pool body when the groundwater level is high is effectively solved by the sandwich structure. The sandwich material can automatically expand when the groundwater level rises to form a supporting force to resist the buoyancy of the water on the bottom of the pool, thereby preventing the pool body from floating up. This design breaks through the application limitations of traditional flexible pool bodies in areas with high groundwater levels, broadens the scope of use of flexible pool bodies, and enables them to be used in more areas, especially in places with poor foundations, high groundwater levels and high requirements for water storage capacity. Coastal areas, areas with abundant groundwater resources, and urban underground spaces, etc., these areas often face problems such as high groundwater levels and unstable foundations, and traditional flexible pool bodies are difficult to meet the needs. The anti-floating buffer flexible pool can effectively solve these problems and provide a safe and reliable water storage solution for these areas.

[0042] In the present invention, the flexible pool body is more convenient and quick during the construction process, with a short construction period, and there is no need to build a complex groundwater drainage system, thereby reducing the project cost. In addition, the use of interlayer materials also makes the pool body lighter and easier to transport and install. In terms of operation and management, since the interlayer can automatically adjust the pressure, there is no need for special personnel to monitor and adjust, which further reduces the management cost. These factors work together to make the anti-floating buffer flexible pool have higher economic benefits. In occasions such as temporary water supply and temporary sewage treatment, the flexible pool body can be used to quickly build water storage facilities to meet temporary needs while reducing construction costs and management costs. In addition, in the development of urban underground space, the flexible pool body can save underground space, improve space utilization, and reduce construction costs. Therefore, the flexible pool body has high economic benefits in many fields and has broad application prospects.
