Abstract
Description
Technical Field
[0001] The utility model relates to the field of construction, in particular to a drainage and pressure relief structure for groundwater reverse osmosis. Background Art
[0002] With the frequent occurrence of various extreme weather events (such as heavy rain and snow), especially localized and sporadic heavy rainfall, existing buildings and structures are being damaged. As a result, some older buildings and buildings with inadequate drainage systems are experiencing a sharp increase in groundwater levels due to heavy rainfall, resulting in enormous groundwater pressure and frequent groundwater backflow and infiltration. For example, underground parking lots, power distribution centers, and water service offices in buildings are susceptible to precipitation infiltration, causing ground bulging, cracking, and water seepage. High groundwater pressure directly impacts the structural safety of buildings.
[0003] Therefore, the existing methods to solve the above problems generally use anti-floating anchor rods or anti-pull piles for processing. By locally driving the anti-floating anchor rods, the two ends of the anti-floating anchor rods are respectively fixed to the deeper underground and the bulging and leaking ground, thereby pulling the bulging ground, so that this local area has a certain pulling force, thereby resisting the water pressure; although this method can solve the existing problems of local bulging and water seepage, it still has some shortcomings: for example (1) the anti-floating anchor rods need to open very deep holes (at least 3-5 meters deep into the ground (soil layer)). Since the diameter of the anti-floating anchor rods is very small, they generally open long and narrow holes. It is difficult to open such long and narrow holes, and the end located underground itself is difficult to open. And it is subject to the impact of water pressure, so this end is difficult to stabilize, and the entire construction is difficult. More importantly, this method is a reinforcement method, and the water pressure cannot be relieved. Although the tension is increased by driving the anti-floating anchor rod, other places are still under huge pressure. Therefore, the above method is only a temporary solution; moreover, a large area of site needs to be driven in many anchor rods, and the construction is difficult and costly; and after a period of time, other positions where no anchor rods are driven in will bulge and crack due to the impact of water pressure, and even the water pressure will move to the wall, squeezing the wall to crack, etc., which will cause serious safety hazards to the structure of the building.
[0004] Therefore, there is an urgent need for a method that can stabilize the structure and quickly drain groundwater to solve the above problems. Utility Model Content
[0005] The purpose of the present invention is to overcome the above-mentioned defects or problems existing in the background technology, and to provide a drainage and pressure relief structure for groundwater reverse osmosis, which has a simple structure, is easy to manufacture, easy to implement and has low cost, and solves the problem that the existing ground is lifted or broken due to an extreme surge in water volume, and the groundwater cannot be discharged. The only way to resist the water pressure is to increase the underground tension on the ground by means of anti-floating anchor rods, and the groundwater pressure cannot be eliminated or drained, which affects the safety of the entire building structure.
[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0007] A drainage and pressure relief structure for groundwater reverse osmosis, the drainage and pressure relief structure comprising:
[0008] A pressure relief assembly is inserted and fixed in the rammed earth layer; the pressure relief assembly includes at least one set of integrated diversion pipes and a pressure relief seat, the pressure relief seat being placed in the rammed earth layer and having a water inlet; one end of the diversion pipe is connected to the pressure relief seat in the rammed earth layer, and the other end extends out of the ground to release groundwater pressure in the rammed earth layer;
[0009] A drainage assembly is laid on the ground; the drainage assembly includes a drain pipe assembly and several pressure plates; the drain pipe assembly is used to connect the diversion pipe and the water collection well; the drain pipe assembly includes several interface parts and drainage parts, the interface parts are respectively attached to the end of the diversion pipe exposed on the ground and the drainage parts; each drainage part is connected to each water collection well to divert groundwater to the water collection well; the pressure plates are laid flat along the ground and connected to the sides of the drainage parts to allow groundwater seeping from the pressure plates to enter the drainage parts;
[0010] A geotextile layer, which is used to cover the pressure relief seat, drainage components, and is laid on the pressure plate;
[0011] A crushed stone layer is laid on the geotextile layer, and a concrete layer is provided on the crushed stone layer.
[0012] Furthermore, the outer side surfaces of the interface member, the drainage plate and the pressure plate are respectively installed by limiting the position by nailing, so that the interface member, the drainage plate and the pressure plate are fixed to the ground.
[0013] From the above description of the present invention, it can be seen that compared with the prior art, the present invention has the following beneficial effects:
[0014] (1) The utility model provides a drainage and pressure relief structure for groundwater reverse osmosis, which has a simple structure, is easy to make, easy to implement and has low cost; it breaks the traditional way of only adding anti-floating anchor rods to solve the limitations of ground bulging, cracking and water seepage, and adopts an integrated drainage system to quickly and effectively discharge groundwater (especially groundwater with a sharp increase in groundwater due to extreme weather) to various water collection wells, eliminating groundwater pressure, and is an active anti-floating and anti-seepage measure that treats both the symptoms and the root cause; the utility model adopts a pressure relief component to be introduced into the rammed earth layer, so that the groundwater is directly led from the pressure relief seat and the diversion pipe to the ground, and is introduced into various water collection wells through the drainage components ; It should be noted that the original water collection wells are not flat at all, which prevents groundwater from flowing to some higher water collection wells. Such water collection wells cannot play a drainage role. However, the height difference is adjusted after the drainage parts of the utility model are laid, so that each water collection well can play a good role in water distribution and drainage. Not only that, the pressure plate can play a good load-bearing role. Even if there is groundwater infiltration, the water level is lower than the pressure plate and can enter the side of the drainage part. In the case of a surge in groundwater, it can be quickly discharged to each water collection well through the inside of the drainage part, thereby releasing, dredging, draining and depressurizing the groundwater from the source, reducing the buoyancy of groundwater on the ground.
[0015] (2) The pressure relief seat of the present invention is arranged in a cone shape, and a number of water inlets are respectively provided on the peripheral wall and the bottom wall, so that the groundwater filtered by the gravel layer and the geotextile can smoothly enter the pressure relief seat. In particular, the cone design prevents the instantaneous water pressure generated by the surge of groundwater from impacting the outer peripheral wall of the pressure relief seat, plays a good pressure-relieving role, and guides the groundwater to smoothly enter the pressure relief seat.
[0016] (3) The utility model also provides a water-stop baffle on the guide pipe of the pressure relief assembly. The soil backfilled to the outer periphery of the guide pipe effectively suppresses the water-stop baffle, so that the entire pressure relief assembly will not move upward. At the same time, groundwater is not easy to float up along the wall of the guide pipe, which plays a good role in bearing pressure and resisting floating.
[0017] (4) The drainage component of the present invention is composed of a plurality of plates with S-shaped cross-sections stacked together. It can not only drain water quickly, but also is not easily deformed when subjected to external forces, and is not easy to reduce the drainage area. In addition, the side surfaces of the S-shaped plates can also be used for drainage. When the water level rises rapidly, the side surfaces can also receive groundwater flowing between the pressure plates for further drainage.
[0018] (5) The drainage components of the present invention are arranged in a grid and form an area for laying the pressure plate, so that the intervals between the various support bodies on the pressure plate can be connected to the drainage components, making drainage more effective, and the pressure bearing capacity better, and it is also easier to transport groundwater to the water collection well.
[0019] (7) The support body of the utility model is arranged in an inverted cone shape, which not only has a good load-bearing capacity (withstanding a gravity of at least 5 tons), but also has a larger space in the interval part, so that the drainage effect is better. Then, it is fixed with nails, and the entire structure is stable and has a good pressure-bearing effect.
[0020] (8) The utility model also provides a pressure sensor and installs it in the pressure relief seat, which can monitor the pressure of groundwater in real time or at manually set time nodes, and intelligently monitor the state of groundwater to facilitate the adoption of various emergency measures.

Obviously, the described embodiments are preferred embodiments of the present invention and should not be regarded as excluding other embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.
[0028] In the claims, description and the above-mentioned drawings of the present utility model, unless otherwise clearly defined, the use of terms such as "first", "second" or "third" is to distinguish different objects rather than to describe a specific order.
[0029] In the claims, specification and the above-mentioned drawings of the present utility model, unless otherwise expressly defined, directional words, such as the terms "center", "transverse", "longitudinal", "horizontal", "vertical", "top", "bottom", "inside", "outside", "up", "down", "front", "back", "left", "right", "clockwise", "counterclockwise" and the like, indicating directions or positional relationships are based on the directions and positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the specific protection scope of the present utility model.
[0030] In the claims, specification and the above drawings of the present utility model, unless otherwise clearly defined, if the terms "fixed connection" or "fixed connection" are used, they should be understood in a broad sense, that is, any connection method without any displacement relationship and relative rotation relationship between the two parties, that is to say, including non-detachable fixed connection, detachable fixed connection, integral connection and fixed connection through other devices or elements.
[0031] In the claims, description and drawings of the present utility model, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".
[0032] See also Figure 1-5 The utility model discloses a drainage and pressure relief structure for groundwater reverse osmosis, which is suitable for underground areas such as basements, parking lots, underground passages, and stations. The drainage and pressure relief structure of the utility model includes:
[0033] The pressure relief assembly 2 is inserted and fixed in the rammed earth layer 1; the pressure relief assembly 2 includes at least one set of integrated guide pipes 21 and a pressure relief seat 22, the pressure relief seat 22 is placed in the rammed earth layer 1, and is provided with a plurality of water inlets 221, wherein the water inlets 221 are respectively provided on the peripheral wall and the bottom wall of the pressure relief seat 22, so that the water inlets 221 of the entire pressure relief seat 22 are distributed in a mesh-like manner; it should be noted that the utility model also sets the cross-sectional shape of the pressure relief seat 22 in a conical shape, and each water inlet 221 is also inclined with the side wall, so that the high-pressure groundwater will not instantly impact and squeeze the side wall, and the water will flow more smoothly into the pressure relief seat 22 and out of the guide pipe 21;
[0034] One end of the diversion pipe 21 is connected to the pressure relief seat 22 located in the rammed earth layer 1 (the utility model uses welding to connect the pressure relief seat 22 and the diversion pipe 21 so that the two are connected as a whole and have sufficient compressive strength). The other end extends out of the ground D to release the groundwater pressure in the rammed earth layer 1. The other extended end is welded to the drain pipe group 31 of the drainage assembly 3.
[0035] Not only that, a water-stop baffle 23 is formed by radially extending outward on the outer peripheral wall of the guide pipe 21. In this embodiment, the annular water-stop baffle 23 is fixed to the outer peripheral wall of the guide pipe 21 by welding to limit the up and down movement of the pressure relief assembly 2 in the rammed earth layer 1. When subjected to water pressure, the upper surface of the water-stop baffle 23 is pressed by the backfill soil, which makes it difficult for the entire guide pipe 21 and the pressure relief seat 22 to float up and down, and prevents groundwater from seeping out along the outer peripheral wall of the guide pipe 21.
[0036] The drainage assembly 3 is laid on the ground D (it should be noted that the ground D here is the ground D that originally had bulges and leakage); the drainage assembly 3 includes a drain pipe group 31 and a plurality of pressure plates 32;
[0037] The drain pipe group 31 is used to connect the diversion pipe 21 and the water collection well;
[0038] The drainage pipe assembly 31 includes a plurality of interface components 311 and drainage components 312. The interface components 311 are respectively connected to the end of the diversion pipe 21 exposed on the ground D and the drainage components 312. It should be noted that the interface components 311 include an inlet end 311A and at least two outlet ends 311B. The inlet end 311A is threadedly connected to the diversion pipe 21 or connected in other ways, while the outlet ends 311B are inserted into the plurality of drainage components 312. This allows water from the diversion pipe 21 to smoothly enter the drainage components 312. The drainage components 312 are connected to various water collection wells to divert groundwater to each water collection well, solving the problem of water being unable to drain water from nearby water collection wells due to bulges in the ground D.
[0039] The drainage component 312 in this embodiment includes a plurality of plates 3120 with an S-shaped cross-section. The plates 3120 are stacked and a drainage channel 3121 is formed between two adjacent plates 3120 . The ends of the stacked plates 3120 are installed in the interface component 311 .
[0040] Then, the drainage members 312 are laid on the ground D in a grid pattern, and each drainage member 312 encloses an area for laying the pressure plate 32 so that at least two sides (or side portions) of the pressure plate 32 are connected to the drainage members 312 .
[0041] It should be noted that the pressure plates 32 of the present invention are laid flat along the ground surface D and are connected to the sides of the drainage members 312, allowing water seeping from the pressure plates 32 to enter the drainage members 312. Each pressure plate 32 includes an integrally formed pressure surface 321 and a plurality of support bodies 322. The support bodies 322 are arranged in a continuous pattern at intervals and form spacers 323 for groundwater to flow toward the sides of the drainage members 312. Furthermore, the pressure surfaces 321 of two adjacent pressure plates 32 are snap-fitted together, preventing groundwater from overflowing beneath the pressure surfaces 321 and causing a single pressure plate 32 to arch.
[0042] Moreover, the support body 322 is hollow and has an inverted cone-shaped cross section, which reduces the weight and material cost of the entire pressure plate 32 while ensuring sufficient support strength.
[0043] The geotextile layer 4 covers the pressure relief seat 22 and the drainage member 312 and is laid on the pressure plate 32 to filter soil impurities and prevent mud from entering the drainage member 312 and clogging it;
[0044] A crushed stone layer 5 is laid on the geotextile layer 4 and a concrete layer 7 is provided thereon.
[0045] In addition, it also includes a pressure sensor 6, which is installed in the pressure relief seat 22 to monitor the groundwater pressure. In this way, the groundwater pressure can be monitored in real time or according to manually set time nodes, and the state of the groundwater can be intelligently monitored to facilitate the adoption of various emergency measures.
[0046] Actual construction and use: see Figure 1-5 ,
[0047] The construction method of the drainage and pressure relief structure of the present invention is described as follows:
[0048] Step 1: Clean the existing ground D surface layer and identify the specific leakage points and / or crack points;
[0049] Step 2: Conduct a survey at the corresponding leakage point, crack point or artificially set location, and drill holes from the ground D down to the rammed earth layer 1. The diameter of the holes should be no less than 200mm (generally the hole diameter is 200-250mm) and the depth should be no less than 250mm (250-300mm). This depth is shallow and easy to achieve and does not affect the structural stability of the original ground D. After laying a geotextile in the hole, lay a crushed stone layer 5;
[0050] Step 3: The pressure relief seat 22 is configured as a conical hollow design. A geotextile layer 4 for water filtration is then wrapped around the outer periphery of the inverted conical pressure relief seat 22 (it should be noted that the geotextile layer 4 is a filament geotextile), and a sensor for detecting water pressure is fixedly installed. It should be noted that the sensor here is connected to a controller with a power supply function on the side wall via a waterproof electrical wire; after being connected to the interface component 311, it is placed in the hole.
[0051] Step 4: Install an upper interface part 311 and a water stop baffle on one end of the guide pipe 21 connected to the pressure relief seat 22, and place it on the ground D, and thread or weld the interface part 311 to the pressure relief seat 22; after placing the pressure relief seat 22 on the rammed earth layer 1, fill the gravel layer 5 on the periphery of the geotextile layer 4, and then backfill the soil into the hole (that is, after the pressure relief seat 22 and the guide pipe 21 covered with the geotextile layer 4 are placed on the gravel layer 5, backfill the gravel layer 5 on the side of the pressure relief seat 22, so that there is a gravel layer 5 on the side and bottom of the pressure relief seat 22; then backfill with soil or concrete; the installation of the pressure relief assembly 2 is completed); at least two water outlet ends 311B are formed on the interface part 311 (the water outlet ends 311B of the interface part 311 here are selected according to the actual arrangement of the drainage parts 312, and can be set to a cross shape, a straight shape or a T shape, etc.);
[0052] Step 5: Stack and arrange the S-shaped plates 3120 into drainage components 312, and form a plurality of drainage channels 3121 for groundwater to flow axially. By stacking the S-shaped plates 3120, water can flow through the plates, and the pressure bearing capacity is strong enough and not easy to deform. After stacking, the plates are covered with a geotextile layer 4, and one end of each drainage component 312 is inserted into the water outlet end 311B of the interface component 311, and the other end is connected to the water outlet end 311B of the water collection well or other interface components 311, so that the drainage components 312 are finally arranged in a grid. Areas are formed between the drainage components 312 in the grid arrangement for laying pressure plates 32, thereby formatting the drainage path.
[0053] Step 6: After splicing and sealing each pressure plate 32 (the pressure plates 32 of the present invention are overlapped with each other by snap-fitting to form a sealed pressure surface, and the overlapping positions are sealed with tape to allow leaked groundwater to flow under the pressure plate 32 and enter the sides of each drainage plate for discharge), they are then laid flat to the area enclosed by each drainage member 312, so that each support body 322 is located on the ground D and the groundwater is located below the pressure surface 321; each pressure plate 32 is connected to each other and is connected to the side of the drainage member 312; after laying, the outer side surface of the interface member 311 and the pressure plate 32 are respectively installed with nails (not shown in the figure) to limit the interface member 311 and the pressure plate 32 to be fixed to the ground D and not easy to loosen or move.
[0054] Step 7: Lay the geotextile layer 4 flat on the drainage board, the interface member 311 and the pressure plate 32;
[0055] Step 8: Lay a crushed stone layer 5 on the geotextile layer 4;
[0056] Step 9: Lay the geotextile layer 4 and the steel bar layer 8 on the gravel layer 5, and then pour the concrete layer 7.
[0057] When encountering a situation where extreme weather causes a sharp increase in groundwater, groundwater can enter several pressure relief seats 22 through the gravel layer 5 and the geotextile layer 4, and the gravel layer 5 and the geotextile layer 4 block the mud and sand to avoid clogging the water inlet 221 of the pressure relief seat 22; after the groundwater enters, the pressure sensor 6 can measure the real-time pressure value of the groundwater, and then divert it from the pressure relief seat 22 and the diversion pipe 21 (i.e., pressure relief), and the groundwater flows downstream to the interface part 311, and then is discharged to each water collection well by the S-shaped drainage part 312 connected to the interface part 311. In this way, it is quickly dispersed to each water collection well, ensuring that each water collection well can be used, avoiding This avoids the situation where some water collection wells are not used, forming a grid-like pressure and water distribution; in addition, even if some groundwater seeps out, it can only flow under the pressure surface 321 of the pressure plate 32, between the partitions 323, and finally flow to the side of the drainage component 312, and follow the drainage component 312 to be discharged to the water collection well; this can ensure that the groundwater pressure is discharged in time, ensure the stability of the basement floor structure, and thus reduce the possibility of arching or floating due to excessive groundwater pressure; not only that, this method also reduces the pressure on the wall structure, and after the pressure is released, the water pressure acting on the wall is reduced, preventing the wall from cracking, moisture, etc.
[0058] The utility model provides a drainage and pressure relief structure for groundwater reverse osmosis, which has a simple structure, is easy to manufacture, easy to implement and low in cost; it breaks the traditional method of only adding anti-floating anchor rods to solve the limitations of ground bulging, cracking and water seepage, and adopts an integrated drainage system to quickly and effectively drain groundwater (especially groundwater with a sharp increase in groundwater volume due to extreme weather) to various water collection wells, eliminating groundwater pressure, and is an active anti-floating and anti-seepage measure that treats both the symptoms and the root cause; the utility model adopts a pressure relief component to be introduced into the rammed earth layer, so that the groundwater is directly led to the ground from the pressure relief seat and the diversion pipe, and is introduced into various water collection wells through the drainage component; It should be noted that the original water collection wells are not flat in height, which prevents groundwater from flowing to some higher water collection wells. Such water collection wells cannot play a drainage role. However, after the drainage parts of the present invention are laid, the height difference is adjusted, which can enable each water collection well to play a good role in water diversion and drainage. Not only that, the pressure plate can play a good load-bearing role. Even if there is groundwater infiltration, the water level is lower than the pressure plate and can enter the side of the drainage part. In the case of a surge in groundwater, it can be quickly discharged to each water collection well through the inside of the drainage part, releasing the pressure of the groundwater from the source, dredging, draining and depressurizing, and reducing the buoyancy of the groundwater on the ground. The pressure relief seat of the present invention is arranged in a cone shape, and a number of water inlets are respectively opened on the peripheral wall and the bottom wall, so that the groundwater filtered by the gravel layer and the geotextile can smoothly enter the pressure relief seat. In particular, the cone design prevents the instantaneous water pressure generated by the surge in groundwater from impacting the outer wall of the pressure relief seat, plays a good pressure relief role, and guides the groundwater to smoothly enter the pressure relief seat. The present invention also provides a water-stop baffle on the guide pipe of the pressure relief assembly. The soil backfilled to the outer periphery of the guide pipe effectively suppresses the water-stop baffle, so that the entire pressure relief assembly will not move upward. At the same time, groundwater is not easy to float up along the wall of the guide pipe, playing a good role in bearing pressure and resisting floating. The drainage component of the present invention is composed of a plurality of plates with S-shaped cross-sections stacked together. It can not only drain water quickly, but also is not easy to deform when subjected to external forces, and is not easy to reduce the drainage area. In addition, the side of the S-shaped plate can also be used for drainage. When the water level rises rapidly, the side can also receive the groundwater flowing between the pressure plates for further drainage. The drainage components of the present invention are arranged in a grid and form an area for laying the pressure plates, so that the intervals between the various support bodies on the pressure plates can be connected to the drainage components, making drainage more effective, and the pressure bearing capacity better, and it is also easier to transport groundwater to the water collection well. This new design features an inverted cone-shaped support structure, which not only provides excellent load-bearing capacity (withstanding at least 5 tons of gravity), but also provides a larger space in the partitions, resulting in better drainage and drainage. Furthermore, the structure is secured with nails, ensuring a stable and effective pressure-bearing structure. This new design also incorporates a pressure sensor, installed within the pressure relief seat, that can monitor groundwater pressure in real time or at preset time points, intelligently monitoring groundwater status and facilitating the implementation of various emergency measures.
[0059] The above description of the specification and embodiments is used to explain the protection scope of the present utility model, but does not constitute a limitation on the protection scope of the present utility model.
