Description

Technical Field

[0001] The present application relates to the technical field of diaphragm wall construction in civil engineering, and in particular to a diaphragm wall plugging structure with simple construction. Background Art

[0002] The diaphragm wall, abbreviated as the D-wall, is a mature underground building structure. With the development of modern construction projects, especially in the construction of underground structures such as subway stations, underground shopping malls, and underground garages, the diaphragm wall, as the surrounding structure in the middle and south Asia, its construction quality and efficiency are crucial for the success of the entire project.

[0003] The general construction method of the D-wall is as follows: Use an excavator to dig out a groove in the ground where the D-wall is to be installed in advance, then vertically install I-beams in the groove, then install a pre-welded steel reinforcement cage between the adjacent I-beams, and then pour concrete into the steel reinforcement cage. In order to facilitate the placement of the steel reinforcement cage into the notch of the I-beam, there is generally a gap between the outer contour of the steel reinforcement cage and the groove wall of the I-beam. When pouring concrete, the concrete flows around along the gap between the steel reinforcement cage of the first pour and the groove wall to the area of the subsequent pour that has not been constructed, resulting in an unsafe structure of the D-wall and increasing the construction difficulty of installing the D-wall in the area of the subsequent pour. For this reason, in the prior art, a flexible water bag is installed in the back notch of the I-beam of the D-wall, that is, in the subsequent pour area, to solve the problem of concrete bypass flow. After the concrete in the steel reinforcement cage is cured, the flexible water bag is lifted out by a crane.

[0004] However, the water bag is made of a flexible material. During repeated use, the water bag may be damaged. Sometimes these damages cannot be found before installing the water bag. When the water bag is installed underground, the damage continues to expand, thus reducing the function of the water bag to prevent bypass flow. At this time, the water bag needs to be lifted out and replaced, which further increases the construction period. For this reason, the present application provides a diaphragm wall plugging structure with simple construction. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the present utility model application is to provide a diaphragm wall plugging structure with simple construction, so as to solve the problems in the prior art that after the water bag has minor damages after repeated use, the damages continue to expand when installed underground, reducing the function of preventing bypass flow, and replacing the water bag again, increasing the construction period.

[0006] The above object of the present application is achieved through the following technical solutions: A diaphragm wall plugging structure with simple construction includes a water bag. A plurality of flexible sub-compartment bags are arranged in the water bag cavity in an array from top to bottom. The outer walls of the plurality of flexible sub-compartment bags are connected to the inner wall of the water bag. A connecting water pipe is connected between adjacent flexible sub-compartment bags among the plurality of flexible sub-compartment bags. The plurality of flexible sub-compartment bags divide the water bag into a plurality of sub-compartments.

[0007] By adopting the above technical solution, during the repeated use of the water bag, the water bag may be damaged, and these damages may not be discovered sometimes before installing the water bag. When the water bag is installed underground, since the existing water bag seals the notch of the I-beam through its own elastic deformation to prevent the concrete from flowing around, after the water bag is filled with water, a large pressure will be generated inside it. Therefore, the damaged part of the water bag will continue to expand, thereby reducing or even losing the function of preventing the flow around. At this time, a new water bag needs to be reinstalled, which will increase the construction period. In this application, a plurality of flexible sub-compartment bags are arrayed from top to bottom in the inner cavity of the water bag. The outer walls of the plurality of flexible sub-compartment bags are connected to the inner wall of the water bag, and the plurality of flexible sub-compartment bags divide the inner part of the water bag into a plurality of independent sub-compartment chambers. When one of the sub-compartment chambers leaks, it will not affect the plugging function of other sub-compartment chambers. Compared with the existing water bag, the water bag structure of this application does not need to replace the new water bag, thus not affecting the construction period. And compared with the existing water bag, even if the water bag is partially damaged, the cooperation between the water bag and the flexible sub-compartment bag can ensure the anti-flow-around function of the water bag.

[0008] In a further optimized solution, a sealing plate is installed at the upper end of the water bag, and a plurality of water inlet pipes are installed on the sealing plate. The plurality of water inlet pipes are all communicated with the water bag. The water inlet pipes are adapted to the number of sub-compartment chambers, and a water valve is connected to each water inlet pipe.

[0009] By adopting the above technical solution, a plurality of water inlet pipes are installed on the sealing plate, and the number of water inlet pipes is the same as the number of sub-compartment chambers. A water valve is respectively connected to each water inlet pipe. When a leakage occurs in one of the sub-compartment chambers of the water bag, the problematic sub-compartment chamber can be individually closed, so as not to affect the anti-flow-around function of other sub-compartment chambers. At the same time, after the water in the problematic flexible sub-compartment bag drains out, under the action of gravity, the soft water bags will stack together, and the stacked water bags can also provide an auxiliary anti-flow-around function.

[0010] In a further optimized solution, an independent chamber water inlet pipe is installed in each sub-compartment chamber, and the other end of the chamber water inlet pipe is connected to the water inlet pipe.

[0011] By adopting the above technical solution, since there are a plurality of sub-compartment chambers and each sub-compartment chamber needs to be filled with water, an independent chamber water inlet pipe is installed in each sub-compartment chamber, which can facilitate the filling of water into each sub-compartment chamber. At the same time, if a leakage occurs in the sub-compartment chamber, the water in the problematic sub-compartment chamber can be individually recycled to prevent the water from overflowing into the construction area and affecting the construction.

[0012] In a further optimized solution, a chamber bag water inlet pipe is installed on the sealing plate, and the chamber bag water inlet pipe is communicated with the flexible sub-compartment bag.

[0013] By adopting the above technical solution, through the water inlet pipe of the storage bladder, it is convenient to add or recover water into the flexible partition bladder.

[0014] In a further optimized solution, the connecting water pipe is a rubber hose.

[0015] In a further optimized solution, the water inlet pipe of the chamber is a rubber hose.

[0016] By adopting the above technical solution, since the water bladder folds itself during transportation or storage, by setting the connecting water pipe and the water inlet pipe of the chamber as rubber hoses, the damage of the connecting water pipe and the water inlet pipe of the chamber during use can be effectively avoided, thereby improving the service life of the water bladder.

[0017] In a further optimized solution, a water pressure gauge is connected between the water inlet pipe and the water inlet pipe of the bladder and the water valve.

[0018] By adopting the above technical solution, since there are multiple flexible partition bladders arranged in the water bladder in an array from top to bottom, the flexible partition bladders divide the water bladder into multiple independent chambers. If the water bladder is damaged and leaks, it is impossible to determine the specific position of the leaking chamber. By installing a water pressure gauge between the water inlet pipe and the water valve, the specific position of the leaking chamber can be visually judged.

[0019] In a further optimized solution, water pumps are connected to the water inlet ends of the water inlet pipe and the water inlet pipe of the bladder, and the water pumps are connected to the water storage device.

[0020] By adopting the above technical solution, the water pump fills or recovers water into the water bladder and the flexible partition bladder.

[0021] In summary, the present application includes at least the following beneficial technical effects:

[0022] 1. By arranging multiple flexible partition bladders in an array from top to bottom in the inner cavity of the water bladder, the outer walls of the multiple flexible partition bladders are connected to the inner wall of the water bladder, and the multiple flexible partition bladders divide the inner part of the water bladder into multiple independent chambers. When one of the chambers leaks, it will not affect the plugging effect of other chambers. Compared with the existing water bladder, it is not necessary to replace the new water bladder, thus not affecting the construction period. And compared with the existing water bladder, even if part of the water bladder is damaged, the cooperation between the water bladder and the flexible partition bladder ensures the anti-bypass flow effect of the water bladder.

[0023] 2. By installing multiple water inlet pipes on the encapsulation board, and the number of water inlet pipes being the same as the number of compartment chambers, a water valve is respectively connected to each water inlet pipe. When a leakage occurs in one compartment chamber of the water bladder, the problematic compartment chamber can be individually closed, thus not affecting the anti-bypass flow function of other compartment chambers. At the same time, after the water in the problematic flexible compartment bladder has drained out, under the action of gravity, the soft water bladders will stack together, and the stacked water bladders can also provide an auxiliary anti-bypass flow function.

[0024] 3. By installing an independent chamber water inlet pipe in each compartment chamber, it is convenient to inject water into each compartment chamber. At the same time, if a leakage occurs in the compartment chamber, the water in the problematic compartment chamber can be individually recycled to prevent water from overflowing into the construction area and affecting the construction.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following further elaborates on the present application in conjunction with the accompanying drawings.

[0028] Embodiment, referring to Figure 1 and Figure 2 , an underground diaphragm wall plugging structure with simple construction, including a water bladder 1. A plurality of flexible compartment bladders 2 are arrayed in the inner cavity of the water bladder 1 from top to bottom. The outer walls of the plurality of flexible compartment bladders 2 are connected to the inner wall of the water bladder 1. Connecting water pipes 3 are connected between adjacent flexible compartment bladders 2 among the plurality of flexible compartment bladders 2. The plurality of flexible compartment bladders 2 divide the water bladder 1 into a plurality of compartment chambers 4. During the repeated use of the water bladder 1, damage to the water bladder 1 may occur, and these damages may sometimes not be detected before installing the water bladder 1. When the water bladder 1 is installed underground and water is injected into the water bladder 1, the water bladder 1 seals the notch of the I-beam through its own elastic deformation, thereby preventing the bypass of concrete. After the water bladder 1 is filled with water, a relatively large pressure will be generated inside it. Therefore, the damaged part of the water bladder 1 will continue to expand, thereby reducing or even losing the function of preventing bypass flow. At this time, a new water bladder 1 needs to be reinstalled, but this will increase the construction period. Compared with the existing water bladder 1, the water bladder 1 structure of the present application does not require replacing the new water bladder 1, thus not affecting the construction period. And compared with the existing water bladder 1, even if part of the water bladder 1 is damaged, with the cooperation of the water bladder 1 and the flexible compartment bladder 2, the anti-bypass flow function of the water bladder 1 can still be ensured.

[0029] In the embodiments of the present disclosure, a sealing plate 5 is installed at the upper end of the water bag 1, and a plurality of water inlet pipes 6 are installed on the sealing plate 5. The plurality of water inlet pipes 6 are all connected to the water bag 1, and the number of the water inlet pipes 6 is adapted to the number of the partition chambers 4. A water valve 7 is connected to each water inlet pipe 6. When a leakage occurs in one partition chamber 4 of the water bag 1, the problematic partition chamber 4 can be individually closed, so as not to affect the anti-bypass flow function of other partition chambers 4. At the same time, after the water in the problematic flexible partition bag 2 drains out, under the action of gravity, the soft water bag 1 will stack together, and the stacked water bags 1 can also provide an auxiliary anti-bypass flow function. A chamber bag water inlet pipe 8 is installed on the sealing plate 5, and the chamber bag water inlet pipe 8 is connected to the flexible partition bag 2.

[0030] Specifically, the connecting water pipe 3 is a rubber hose.

[0031] In the embodiments of the present disclosure, an independent chamber water inlet pipe 40 is installed in the partition chamber 4, and the other end of the chamber water inlet pipe 40 is connected to the water inlet pipe 6. It is convenient to inject water into each partition chamber 4. At the same time, if a leakage occurs in the partition chamber 4, the water in the problematic partition chamber 4 can be individually recycled to prevent the water from overflowing into the construction area and affecting the construction.

[0032] Specifically, the chamber water inlet pipe 40 is a rubber hose.

[0033] More specifically, the chamber water inlet pipe 40 can be integrally processed with the wall of the water bag 1, and a water outlet is left on the wall of the water bag 1 in the area of each partition chamber 4. Alternatively, the chamber water inlet pipe 40 is separately arranged in the inner cavity of the water bag 1. When the chamber water inlet pipe 40 is separately arranged in the inner cavity of the water bag 1, since the flexible partition bag 2 installed in the water bag 1 is connected to the inner wall of the water bag 1, when the chamber water inlet pipe 40 passes through the area where the water bag 1 and the flexible partition bag 2 are in contact, a sealing gasket needs to be installed in the contact area for sealing treatment (not shown in the drawings) to prevent different partition chambers 4 from communicating with each other, and at the same time, the wall of the chamber water inlet pipe 40 in this area needs to be strengthened. For example, when the chamber water inlet pipe 40 is manufactured, steel wires are added inside its pipe wall.

[0034] In the embodiments of the present disclosure, a water pressure gauge 9 is arranged between the water inlet pipe 6 and the water valve 7. One end of the water pressure gauge 9 is connected to the water inlet pipe 6, and the other end is connected to the water valve 7. A water pressure gauge 9 is arranged between the chamber bag water inlet pipe 8 and the water valve 7. One end of the water pressure gauge 9 is connected to the chamber bag water inlet pipe 8, and the other end is connected to the water valve 7. When the water bag 1 is installed underground, if the water bag 1 is damaged and leaks, the operator cannot determine the specific position of the leaking partition chamber 4. By installing a water pressure gauge 9 between the water inlet pipe 6 and the water valve 7, the specific position of the leaking partition chamber 4 can be visually determined.

[0035] Specifically, the water pressure gauge 9 is preferably a mechanical water pressure gauge 9.

[0036] In the embodiment of the present disclosure, the water inlet ends of the water inlet pipe 6 and the bladder water inlet pipe 8 are both connected to a water pump 10, and the water pump 10 is connected to the water reservoir. In addition, since a plurality of water inlet pipes 6 and bladder water inlet pipes 8 are installed on the packaging plate 5, when the water pump 10 is connected to the plurality of water inlet pipes 6 and bladder water inlet pipes 8, according to actual conditions, a plurality of water pumps 10 may be configured to be connected to the water inlet pipes 6 and bladders one by one, or a water pump 10 may be configured, and a distributor is connected between the water pump 10 and the plurality of water inlet pipes 6 and bladder water inlet pipes 8, so that a water pump 10 can be used to simultaneously or separately fill or recycle water for the plurality of water inlet pipes 6 and bladder water inlet pipes 8.

[0037] In the specific implementation process, a water inlet pipe 6 and a bladder water inlet pipe 8 are installed on the packaging plate 5 above the water bag 1, and a water pressure gauge 9 is installed on the water inlet pipe 6 and the bladder water inlet pipe 8 respectively. Then, the water pressure gauge 9 and the water valve 7 are connected. The water bag 1 is hoisted into the groove of the I-beam by a hoisting machine. Finally, the water pump 10 is connected, and water is injected into the multiple sub-chambers 4 and the flexible sub-chamber 2 of the water bag 1 at the same time. The water pressure gauge 9 is observed. After the water pressure reaches a predetermined pressure, the water valve 7 is closed to maintain the pressure. If part of the water bag 1 leaks, the staff can judge the leakage in the water bag 1 by checking the value change of the pressure gauge. If leakage occurs, the water pump 10 can be started and then the corresponding water valve 7 can be opened to recover the water in the leaked sub-chamber 4 in the water bag 1.

[0038] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
