Description

Technical Field

[0001] This invention relates to the field of water bag stacking adjustment and control technology, specifically to an automatic control system and method for adjusting the liquid level of water bag stacking preloading. Background Technology

[0002] The surcharge preloading method, which uses water-filled bags as preloading carriers, is gradually being applied to the solidification of soft soil subgrades because it is easy to transport.

[0003] Unlike the load provided by solid materials such as concrete blocks and steel blocks, water bags, as flexible materials, will deform greatly after being filled with water. Uneven settlement of soft foundations, human factors, and natural factors can all make it difficult to form a perfect horizontal plane at the bottom of the stacking platform. This results in different water depths on both sides of the water bag, causing one side of the system to have more water pressure than the other. This leads to under-load or over-load preloading in some areas during the water bag preloading process, affecting the foundation reinforcement effect and exacerbating uneven settlement of the site.

[0004] Therefore, in response to the above problems, an automatic load level adjustment control system and method for water bag preloading is proposed. When the water depths on both sides of the water bag are different, it can automatically and actively adjust the water pressure on both sides, reduce the water pressure on the soft foundation on the side with deeper water, and increase the water pressure on the soft foundation on the side with shallower water, thereby adjusting and repairing the consistency of the load at the bottom of the water bag. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic load level adjustment control system and method for water bag preloading, which can automatically and actively adjust the water pressure on both sides of the water bag when the water depths on both sides are different, reduce the water pressure on the soft foundation on the side with deeper water, and increase the water pressure on the soft foundation on the side with shallower water, thereby adjusting and repairing the consistency of the load at the bottom of the water bag.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic load level adjustment control system for water bag preloading, comprising induction cylinders evenly spaced and fixedly connected on both sides of the bottom end of the water bag, and first bags arranged in an array on the upper side of the water bag and communicating with the inside of the water bag. A limit rod is fixedly connected to the inner side of the top end of the water bag, and a pressure plate is slidably connected to the outer side of the limit rod. The pressure plates are distributed under any array of first bags. The density of the pressure plates is slightly greater than that of water. The pressure plates can move upward to block the inlet of the first bags.

[0007] An anchor pipe is fixedly connected to the inner side of the top of the induction tube. The top of the anchor pipe is connected to a connecting hose. The top of the connecting hose is connected to a second bladder. When the second bladder is not inflated, it can float in the water. When the second bladder is inflated, it can expand and rise under the action of buoyancy, bringing the pressure plate upward.

[0008] The sensor can automatically inflate or deflate the second bag according to changes in water depth.

[0009] The induction cylinder in this invention can take effective actions according to changes in water depth. It uses gas to occupy the upper part of the water on the side where the water becomes deeper, reducing the overall density at that point and thus reducing the water pressure load on the soft surface of the water bag at that location. After the water bag is occupied, the first bladder at the top of the water bag provides spatial compensation. When the second bladder is inflated, it can expand and rise under the action of buoyancy, which will pull the pressure plate upward to block the entrance of the first bladder at that location. The water squeezed out by the occupancy on the side where the water becomes deeper enters the first bladders other than those at that location, that is, the liquid level at other locations rises, increasing the load on the soft surface outside that location, thereby achieving adjustment and correction.

[0010] As a preferred embodiment of the automatic load level adjustment control system for water bag preloading of the present invention, the first bag is made of elastic material, which expands from the inside under a certain pressure and has contractile properties. The first bag can be referred to as an elastic water ball. The second bag is made of PVC material and can be inflated from the inside. The second bag is similar to a swimming ring.

[0011] As a preferred embodiment of the automatic load level adjustment control system for water bag preloading of the present invention, a water passage hole is provided on the inner side of the top of the sensing cylinder. The water passage hole connects the inner and outer sides of the top of the sensing cylinder for sensing water pressure. The presence of the water passage hole allows the water pressure to act directly on the piston. The piston is slidably connected to the inner side of the sensing cylinder. The position of the sensing cylinder below the piston is a pneumatic chamber. The pneumatic chamber contains compressed gas, which can resist water pressure. When the water changes from shallow to deep, the water pressure increases, and the piston further compresses the pneumatic chamber and moves downward.

[0012] When the water becomes shallower, the water pressure decreases, and the air pressure chamber moves upward against the piston.

[0013] In a preferred embodiment of the automatic load level adjustment control system for water bag preloading of the present invention, the bottom end of the induction cylinder is fixedly connected to a valve, the output end of which is connected to the air pressure chamber for adjusting the amount of compressed gas in the air pressure chamber. This can change the sensitivity of the piston to changes in water depth. When the span of the left and right sides of the water bag is large, the sensitivity can be increased accordingly to ensure timely adjustment.

[0014] As a preferred embodiment of the automatic load level adjustment control system for water bag preloading of the present invention, a connecting pipe is provided on the inner side of the piston component. The connecting pipe is connected to the bottom end of the anchor pipe through a sufficient amount of flexible hose. The second bag is inflated or deflated through the connecting pipe, flexible hose, anchor pipe, and connecting hose. Here, the flexible hose refers to the flexible hose between the connecting pipe and the anchor pipe. The sufficient amount of flexible hose needs to be long enough to support the piston component to slide within the entire sliding stroke of the induction cylinder.

[0015] As a preferred embodiment of the automatic load level adjustment control system for water bag preloading of the present invention, the automatic adjustment control system further includes a gas pressure tank. The output end of the gas pressure tank is connected to a pressure main pipe, and the pressure main pipe is connected to several pressure sub-tubes. The pressure sub-tubes are internally supported tubes. The gas in the gas pressure tank can be transmitted to each sensing cylinder through the pressure main pipe and the pressure sub-tubes. The pressure sub-tubes are inserted inside the bottom end of the water bag. An air inlet is opened at the lower middle position of the sensing cylinder. The air inlet is connected to the pressure sub-tubes through the tubes. When the water depth increases, the piston moves the connecting pipe downward and connects with the air inlet. The compressed gas inside the gas pressure tank can be injected into the second bag on the side where the water depth increases, occupying the upper water on the side where the water depth increases, reducing the water pressure load on the soft soil surface at that position. The water squeezed out by occupying the water on the side where the water depth increases enters the first bag other than that position, increasing the load on the soft soil surface other than that position, thereby realizing adjustment and repair.

[0016] As a preferred embodiment of the automatic load level adjustment control system for water bag preloading of the present invention, a pressure sensor is provided inside the gas pressure tank, and an air pump is fixedly connected to the outside of the gas pressure tank. The output end of the air pump is connected to the inside of the gas pressure tank, and the pressure inside the gas pressure tank is stabilized through the air pump.

[0017] In a preferred embodiment of the automatic load level adjustment control system for water bag preloading of the present invention, an exhaust hole is provided in the middle of the induction cylinder. The exhaust hole is connected to the outside of the water bag through an exhaust hose. After the adjustment is completed, when the piston moves upward, the exhaust hole is connected to the connecting pipe, and the gas in the second bag is discharged under the action of water pressure.

[0018] In a preferred embodiment of the automatic load level adjustment control system for water bag preloading of the present invention, limit blocks are fixedly connected to both the upper and lower positions of the inner side of the sensing cylinder. When the bottom end of the piston abuts against the lower limit block, the connecting pipe is connected to the air inlet. The upper limit block is set below the water passage hole. When the top end of the piston abuts against the upper limit block, the connecting pipe can maintain communication with the exhaust hole. The upper limit block is set below the water passage hole to prevent the piston from blocking the water passage hole.

[0019] The steps of the automatic adjustment and control method for the load level in water bag preloading are as follows:

[0020] Step 1: Level the soft soil, move the water bag to the desired location on the soft soil, and fill the water bag with water until it is full. Note that the first bag is not filled with water.

[0021] Step 2: When the water depth on either side of the water bag increases due to environmental changes, the piston in the corresponding sensing cylinder will drive the connecting pipe downwards and connect with the air inlet. The compressed gas inside the gas pressure tank can then be injected into the second bag on the side with deeper water, occupying the water on that side and reducing the load on the bottom of the water bag at that position. Furthermore, because the second bag on the side with deeper water rises, it blocks the entrance of the first bag at its top. The water squeezed out from the side with deeper water due to the occupation enters the first bag outside that position, reducing the bottom load on the side with deeper water and increasing the bottom load outside that position, thereby achieving adjustment and repair.

[0022] Step 3: The vent is connected to the outside of the water bag via the vent hose. As adjustments are made, the original water depth gradually becomes shallower. When the water depth on both sides of the water bag becomes consistent, the original water depth position will move upward due to the decrease in water pressure and the opposing action of the air pressure chamber. This will connect the vent to the connecting pipe, and under the action of water pressure, the gas in the second bag will be expelled, thus achieving cyclic adjustment.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. The automatic load level adjustment control system for water bag preloading in this invention, the induction cylinder can take effective action according to the change of water depth. It occupies the upper part of the water on the side where the water is deeper with gas, reducing the overall density at that point, thereby reducing the water pressure load on the soft soil surface of the water bag at that position. After occupancy, the first bladder set at the top of the water bag provides spatial compensation. Because the second bladder can expand when inflated and rise under the action of buoyancy, it pulls the pressure plate upward to block the entrance of the first bladder at that position. The water squeezed out by occupancy on the side where the water is deeper enters the first bladders other than that position, that is, the liquid level at other positions rises, increasing the load on the soft soil surface outside that position, thereby achieving adjustment and correction.

[0025] 2. The automatic load level adjustment control system for the water bag preloading has a valve fixedly connected to the bottom of the induction cylinder. The output end of the valve is connected to the air pressure chamber to adjust the amount of compressed gas in the air pressure chamber. This can change the sensitivity of the piston to changes in water depth. When the span of the left and right sides of the water bag is large, the sensitivity can be increased accordingly to ensure timely adjustment.

[0026] 3. The automatic load level adjustment control system for water bag preloading transmits gas from the gas pressure tank to each sensing cylinder through a pressure main pipe and pressure sub-hose. The pressure sub-hose passes through the bottom inner side of the water bag. An air inlet is located in the lower middle position of the sensing cylinder. The air inlet is connected to the pressure sub-hose through a hose. When the water depth increases, the piston moves the connecting pipe downward and connects with the air inlet. The compressed gas inside the gas pressure tank can be injected into the second bag on the side where the water depth increases, occupying the upper part of the water on the side where the water depth increases. This reduces the water pressure load on the soft soil surface at that position. The water squeezed out by occupying the water on the side where the water depth increases enters the first bag other than that position, increasing the load on the soft soil surface other than that position, thereby achieving adjustment and repair.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1, please refer to Figure 1-10 The present invention provides a technical solution:

[0041] The automatic adjustment and control system for the load liquid level of the water bag stacking preloading includes induction cylinders 5 that are evenly spaced and fixedly connected on both sides of the bottom end of the water bag 2, and first bags 4 that are arrayed on the upper side of the water bag 2 and communicate with the inside of the water bag 2. A limit rod 41 is fixedly connected to the inner side of the top of the water bag 2, and a pressure plate 42 is slidably connected to the outer side of the limit rod 41. The pressure plate 42 is distributed under any array of first bags 4. The density of the pressure plate 42 is slightly greater than that of water. The pressure plate 42 can move upward to block the inlet of the first bag 4.

[0042] An anchor pipe 55 is fixedly connected to the inner side of the top of the induction tube 5. The top of the anchor pipe 55 is connected to a connecting hose 53. The top of the connecting hose 53 is connected to a second bladder 52. When the second bladder 52 is not inflated, it can float in the water. When the second bladder 52 is inflated, it can expand and rise under the action of buoyancy, bringing the pressure plate 42 upward.

[0043] The sensor cylinder 5 can automatically inflate or deflate the second bag 52 according to changes in the water depth it is in.

[0044] The sensing cylinder 5 in this invention can take effective actions according to the changes in water depth. It uses gas to occupy the upper part of the water on the side where the water becomes deeper, reducing the overall density at that point. This reduces the water pressure load on the soft base 1 surface of the water bag 2 at that location. After the water bag 2 is occupied, the first bag 4 at the top of the water bag 2 provides space compensation. When the second bag 52 is inflated, it can expand and rise under the action of buoyancy, pulling the pressure plate 42 upward to block the entrance of the first bag 4 at that location. The water squeezed out by the occupancy on the side where the water becomes deeper enters the first bag 4 outside of that location, that is, the liquid level at other locations rises, increasing the load on the soft base 1 surface outside of that location, thereby achieving adjustment and correction.

[0045] Specifically, the first pouch 4 is made of elastic material, which expands from the inside under certain pressure and has contractile properties. The first pouch 4 can be compared with an elastic water balloon. The second pouch 52 is made of PVC material and can be inflated from the inside. The second pouch 52 is similar to a swimming ring.

[0046] Specifically, a water passage hole 57 is provided on the inner side of the top of the sensing cylinder 5. The water passage hole 57 connects the inner and outer sides of the top of the sensing cylinder 5 for sensing water pressure. The presence of the water passage hole 57 allows the water pressure to act directly on the piston 51. The piston 51 is slidably connected to the inner side of the sensing cylinder 5. The position of the sensing cylinder 5 below the piston 51 is the air pressure chamber 59. The air pressure chamber 59 contains compressed gas, which can resist water pressure. When the water changes from shallow to deep, the water pressure increases, and the piston 51 further compresses the air pressure chamber 59 and moves downward.

[0047] When the water becomes shallower, the water pressure decreases, and the air pressure chamber 59 moves upward against the piston 51.

[0048] Specifically, the bottom end of the induction cylinder 5 is fixedly connected to a valve 510. The output end of the valve 510 is connected to the air pressure chamber 59 and is used to adjust the amount of compressed gas in the air pressure chamber 59. This can change the sensitivity of the piston 51 to changes in water depth. When the span between the left and right sides of the water bag is large, the sensitivity can be increased accordingly to ensure timely adjustment.

[0049] Specifically, a connecting pipe 56 is provided on the inner side of the piston 51. The connecting pipe 56 is connected to the bottom end of the anchor pipe 55 through a sufficient hose. The second bladder 52 can be inflated or deflated through the connecting pipe 56, the hose, the anchor pipe 55, and the connecting hose 53. Here, the hose refers to the hose between the connecting pipe 56 and the anchor pipe 55. The sufficient hose needs to be long enough to support the piston 51 to slide within the entire sliding stroke of the induction cylinder 5.

[0050] Specifically, the automatic adjustment and control system also includes a gas pressure tank 3. The output end of the gas pressure tank 3 is connected to a pressure main pipe 32, and the pressure main pipe 32 is connected to several pressure sub-tubes 33. The pressure sub-tubes 33 are internally supported tubes. Through the pressure main pipe 32 and the pressure sub-tubes 33, the gas in the gas pressure tank 3 can be transmitted to each sensing cylinder 5. The pressure sub-tubes 33 are inserted inside the bottom end of the water bag 2. An air inlet 512 is opened at the lower middle position of the sensing cylinder 5. The air inlet 512 is connected to the pressure sub-tubes 33. Pipe 33 is connected by a flexible hose. When the water depth increases, piston 51 drives connecting pipe 56 to move downward and connect with air inlet 512. Compressed gas inside gas pressure tank 3 can be injected into the second bag 52 on the side where the water depth increases, occupying the upper part of the water on the side where the water depth increases, reducing the water pressure load on the surface of soft base 1 of water bag 2 at that position. Water squeezed out by occupying the water on the side where the water depth increases enters the first bag 4 outside that position, increasing the load on the surface of soft base 1 outside that position, thereby achieving adjustment and repair.

[0051] Specifically, a pressure sensor is installed inside the gas pressure tank 3, and an air pump 31 is fixedly connected to the outside of the gas pressure tank 3. The output end of the air pump 31 is connected to the inside of the gas pressure tank 3, and the pressure inside the gas pressure tank 3 is stabilized through the air pump 31.

[0052] Specifically, an exhaust port 511 is provided in the middle of the induction cylinder 5. The exhaust port 511 is connected to the outside of the water bag 2 through the exhaust hose 54. After the adjustment is completed, when the piston 51 moves upward, the exhaust port 511 is connected to the connecting pipe 56. Under the action of water pressure, the gas in the second bag 52 is exhausted.

[0053] Specifically, limit blocks 58 are fixedly connected to the upper and lower positions of the inner side of the induction cylinder 5. When the bottom end of the piston 51 abuts against the lower limit block 58, the connecting pipe 56 is connected to the air inlet 512. The upper limit block 58 is set below the water passage hole 57. When the top end of the piston 51 abuts against the upper limit block 58, the connecting pipe 56 can maintain communication with the exhaust hole 511. The upper limit block 58 is set below the water passage hole 57 to prevent the piston 51 from blocking the water passage hole.

[0054] This invention also discloses an automatic adjustment and control method for the load liquid level in water bag preloading, the steps of which are:

[0055] Step 1: Level the soft base 1, move the water bag 2 to the position where the soft base 1 needs to be placed, and fill the water bag 2 with water until it is full. The first bag 4 is not filled with water.

[0056] Step 2: When the water depth on either side of the water bag 2 increases due to environmental changes, the piston 51 in the corresponding sensing cylinder 5 will drive the connecting pipe 56 to move downward and connect with the air inlet 512. The compressed gas inside the gas pressure tank 3 can be injected into the second bag 52 on the side with deeper water, occupying the water on that side and reducing the load force at the bottom of the water bag 2 at that position. Also, because the second bag 52 on the side with deeper water rises, it blocks the entrance of the first bag 4 at its top. The water squeezed out by occupying the water on the side with deeper water enters the first bag 4 outside of that position, reducing the bottom load force on the side with deeper water and increasing the bottom load force outside that position, thereby achieving adjustment and repair.

[0057] Step 3: The vent 511 is connected to the outside of the water bag 2 through the vent hose 54. As the adjustment continues, the original water depth on one side gradually becomes shallower. When the water depth on both sides of the water bag 2 becomes consistent, the original water depth position will move upward due to the decrease in water pressure and the opposing action of the air pressure chamber 59. This will connect the vent 511 to the connecting pipe 56, and under the action of water pressure, the gas in the second bag 52 will be exhausted, thus achieving cyclic adjustment.

[0058] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

When this happens, the compressed gas inside the gas pressure tank (3) can be injected into the second bag (52) on the side with deeper water, occupying the water on the side with deeper water, reducing the load force at the bottom of the water bag (2) at that position. Also, because the second bag (52) on the side with deeper water rises, it blocks the entrance of the first bag (4) at its top. The water squeezed out by occupying the water on the side with deeper water enters the first bag (4) outside of that position, reducing the bottom load force on the side with deeper water and increasing the bottom load force outside that position, thereby achieving adjustment and repair. Step 3: The vent (511) is connected to the outside of the water bag (2) through the vent hose (54). As the adjustment continues, the original water depth on one side gradually becomes shallower. When the water depth on both sides of the water bag (2) becomes consistent, the original water depth position will be reduced due to the decrease in water pressure. Under the counteracting action of the air pressure chamber (59), the piston (51) will move upward, so that the vent (511) is connected to the connecting pipe (56). Under the action of water pressure, the gas in the second bag (52) is exhausted, and the cycle adjustment is realized.
