[0036] refer to Figures 1 to 6 This invention describes a multifunctional drainage consolidation system according to an embodiment of the present invention.
[0037] like Figures 1 to 6 As shown, the multifunctional drainage consolidation system includes multiple drainage bodies 100, which are evenly buried in the foundation and configured to guide the flow of water in the soil 10; a filter network 200, to which the multiple drainage bodies 100 are connected, which is connected to a horizontal vacuum drainage system and configured to vacuum extract water from the soil 10; a pressurization network 300, to which the multiple drainage bodies 100 are connected, which is configured to input and output air; and a pressurization system 400, to which the pressurization system 400 is connected via the pressurization network 300 and configured to clear the drainage bodies 100 to facilitate water flow.
[0038] like Figure 1 and Figure 2 As shown, multiple drainage bodies 100 are evenly inserted vertically into the foundation. In this specific embodiment, the multiple drainage bodies 100 are arranged in a matrix. Each drainage body 100 is connected to the filter pipe network 200 and the booster pipe network 300. The booster system 400 is connected to each drainage body 100 through the booster pipe network 300. Thus, the filter pipe network 200 extracts groundwater from the foundation through the horizontal vacuum drainage system. When soil particles in the deep soft soil cause blockage of the drainage body 100, the booster system 400 applies reverse pressure through the booster pipe network 300, forming a pressure difference between the upper and lower parts of the drainage body 100. This clears the drainage channels inside the drainage board 110, forming a good drainage flow channel and greatly improving the treatment effect of vacuum preloading.
[0039] In some specific embodiments of this utility model, the drainage body 100 includes a drainage plate 110, and the drainage plate 110 is provided with a plurality of protruding ridges 111. The protruding ridges 111 extend along the length direction of the drainage plate 110, and a drainage channel is formed between the plurality of protruding ridges 111 and the drainage plate 110, so that water in the soil 10 flows along the drainage channel. Figure 1 As shown, the drainage board 110 has multiple protruding ridges 111 on both its front and rear sections. These ridges 111 are evenly distributed on the drainage board 110 in the left-right direction and extend along the length of the drainage board 110. A drainage channel is formed between two adjacent ridges 111 along the length of the drainage board 110. Thus, during the foundation treatment process, the filter pipe network 200 applies negative pressure to the area below the drainage board 110 through vacuum preloading technology, causing groundwater and pore water to flow to the area of the drainage board 110 and be discharged through the drainage channel, thereby reducing the moisture content of the foundation soil and improving the soil bearing capacity.
[0040] In some specific embodiments of this utility model, the drainage body 100 further includes a filter membrane 120, which is embedded in all drainage channels and is configured to filter large particles in the soil body 10. For example... Figure 3 As shown, a filter membrane 120 is provided on the drainage board 110. The filter membrane 120 is located at the lower part of the drainage board 110 and is embedded in all the drainage channels. The microporous structure of the filter membrane 120 can effectively prevent soil particles and impurities from entering the interior of the drainage board 110, allowing water to pass through. At the same time, it can also prevent soil erosion of the drainage board 110 structure and protect the integrity and stability of the drainage board 110.
[0041] It should be noted that after the pressurization system 400 applies reverse pressurization through the pressurization pipeline network 300, the pressure difference between the inside and outside of the filter membrane 120 of the drainage plate 110 formed by pressurization can blow away the fine soil particles on the filter membrane 120, so as to reopen the seepage channel of the filter membrane 120 of the drainage body 100 and further ensure the smooth flow of the drainage channel.
[0042] In some specific embodiments of this utility model, such as Figure 1 As shown, the water filtration network 200 includes multiple first branch pipes 210, a water collection pipe 220, and a drain plate connector 230. The number of first branch pipes 210 corresponds to the number of drainage bodies 100. Each drainage body 100 is provided with a corresponding first branch pipe 210. Multiple first branch pipes 210 are connected to the water collection pipe 220. The drainage body 100 is connected to the water collection pipe 220 through the corresponding first branch pipe 210. Each drain plate 110 is provided with a corresponding drain plate connector 230. The drain plate connector 230 is located at the upper end of the drain plate 110 and is configured to define the position of the corresponding first branch pipe 210 on the drain plate 110.
[0043] In some specific embodiments of this utility model, such as Figure 1 As shown, the pressurization network 300 includes multiple second branch pipes 310 and an air collection pipe 320. The number of second branch pipes 310 corresponds to the number of drainage bodies 100. Each drainage body 100 is provided with a corresponding second branch pipe 310. The second branch pipe 310 passes through the drainage channel along the axial direction. Multiple second branch pipes 310 are connected to the air collection pipe 320. The drainage body 100 is connected to the air collection pipe 320 through the corresponding second branch pipe 310.
[0044] In some specific embodiments of this utility model, the drainage board 110 and the second branch pipe 310 are integrally formed.
[0045] In some specific embodiments of this utility model, the second branch pipe 310 is connected to the gas collecting pipe 320 through a straight-through gas pipe quick connector 311.
[0046] In some specific embodiments of this utility model, the bottom of the second branch pipe 310 is set at a depth greater than 6m.
[0047] In some specific embodiments of this utility model, the exposed length of the drainage body 100 ranges from 0.5m to 1m.
[0048] In some specific embodiments of this utility model, the second branch pipe 310 is made of PU material, with an inner diameter of 3mm to 5mm, an outer diameter of 6mm to 8mm, and a working pressure range of -0.1Mpa to 1.5Mpa.
[0049] In some specific embodiments of this utility model, a vacuum system 500 and a vacuum degree measuring system 600 are also included. The vacuum system 500 is connected to the drainage body 100 through a pressurization pipeline 300. The vacuum system 500 is configured to guide the water in the soil 10 to be discharged along the drainage body 100. The vacuum degree measuring system 600 is connected to the drainage body 100 through the pressurization pipeline 300. The vacuum measuring mechanism is configured to measure the vacuum degree distribution of the drainage board 110 along the depth direction.
[0050] The application of this multifunctional drainage consolidation system is illustrated below using three specific embodiments.
[0051] It should be noted that, as Figure 4 As shown, the second branch pipe 310 is connected to the gas collecting pipe 320 via a quick-connect fitting 311, and then connected to the vacuum measurement system 600 via the gas collecting pipe 320 to measure the vacuum level of the drainage body 100 at different depths. Figure 5As shown, the second branch pipe 310 is connected to the gas collecting pipe 320 via a quick-connect fitting 311, and then connected to the vacuum system 500 via the gas collecting pipe 320. At this time, the drain body 100 forms a negative pressure at a set depth on the second branch pipe 310 through the vacuum system 500, achieving bidirectional drainage of the vertical drain body 100 system together with the horizontal vacuum drainage system connected to the filter network 200. Figure 6 As shown, the second branch pipe 310 inside the drainage body 100 is connected to the air collection pipe 320 through the quick-connect fitting 311, and then connected to the pressurization system 400 through the air collection pipe 320. In this specific embodiment, the pressurization system 400 is an air compressor that can pressurize the drainage channel. By spraying compressed air into the second branch pipe 310 at a set depth in the drainage body 100, a pressure difference is formed between the upper and lower parts of the drainage plate 110, which clears the drainage channel and removes the blockage of the filter membrane 120 of the drainage plate 110.
[0052] It should be further noted that the pressurization system 400, the vacuum system 500, and the vacuum degree measurement system 600 can all be individually connected to the gas collection pipe 320. Of course, multiple units of the pressurization system 400, the vacuum system 500, and the vacuum degree measurement system 600 can be selectively connected to the gas collection pipe 320 to achieve multi-functional combined use.
[0053] In Example 1, the vacuum measurement system 600 is connected to the drainage body 100 through the pressurization pipeline network 300.
[0054] Reference Figure 4 As shown, the lower openings of the second branch pipes 310 within the drainage board 110 are set at different depths. In this specific embodiment, each drainage board 110 has one second branch pipe 310. The lower openings of the second branch pipes 310 within different drainage boards 110 are respectively set at positions of 6, 8, 10, and 12 meters underground. Before drainage consolidation, the second branch pipes 310 are connected to the atmosphere. The second branch pipes 310 and the vacuum degree measuring system 600 are sealed together. Under the action of the horizontal vacuum drainage system, the water level in the formation drops. When the groundwater level drops by 5 meters, the water level in the second branch pipes 310 also drops by 5 meters. The vacuum degree measured by the vacuum degree measuring system 600 in different second branch pipes 310 is the same, which is -50 kPa. When the groundwater level drops by 8m, the vacuum degree measured by the vacuum measurement system of the second branch pipe 310 at depths of 6m and 8m is the same as the vacuum degree at depths of 6m and 8m of the drainage board 110. The vacuum degree measured by the vacuum measurement system of the second branch pipe 310 at depths of 10m and 12m is the same, which is -80kPa. Thus, the distribution law of vacuum degree along the drainage board 110 is obtained, that is, the loss rate of vacuum degree along the drainage body 100.
[0055] In Example 2, the vacuum system 500 is connected to the drainage body 100 through the pressurization pipeline network 300.
[0056] Reference Figure 5 As shown, the drainage body 100, installed in the stratum, achieves drainage and consolidation of the soil 10 under the action of the horizontal vacuum drainage system, which is the upper drainage. The second branch pipe 310 in the drainage body 100 is set at a depth of 16m. Through the combined action of the second branch pipe 310 and the vacuum system 500, the drainage body 100 forms a negative pressure at a depth of 16m, realizing drainage at a depth of 16m, which is the lower drainage. This enables bidirectional drainage from both the upper and lower parts of the vertical drainage body 100 system, increasing the treatment depth and improving the treatment effect.
[0057] In Example 3, the pressurization system 400 is connected to the drainage body 100 through the pressurization pipeline network 300.
[0058] Reference Figure 6 As shown, the drainage body 100, installed in the stratum, achieves drainage consolidation of the soil 10 under the action of the horizontal vacuum drainage system. After the drainage consolidation reaches a certain degree, the drainage body 100 deforms under the settlement of the stratum, such as folding. A large number of tiny soil particles are adsorbed around the filter membrane 120 of the drainage board 110, affecting the drainage effect of the drainage body 100. At this time, the second branch pipe 310 and the pressurization system 400 cooperate. The pressurization system 400 sprays compressed air at intervals from the drainage board 110 at a set depth position through the second branch pipe 310. Thus, through the reverse pressurization of the second branch pipe 310, a pressure difference is formed between the upper and lower parts of the drainage board 110. On the one hand, it can clear the drainage channels inside the drainage board 110. On the other hand, the pressure difference between the inside and outside of the filter membrane 120 of the drainage board 110 formed by pressurization can blow away the tiny soil particles on the filter membrane 120, reopen the seepage channels of the filter membrane 120 of the drainage board 110, and form a good drainage channel. This solves the problem of drainage difficulties and weakened vacuum transmission caused by the clogging of the filter membrane 120 in the later stage of the drainage board 110.
[0059] In this specific embodiment, the compressed air injection interval of the booster system 400 is 1 day, the injection duration is 30 minutes, and the injection pressure is 1 MPa to 1.5 MPa.
[0060] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
