Description

Technical Field

[0001] The present invention relates to the technical field of partition gate devices, and in particular to a split partition gate device for a test water pool with an ultra-large aspect ratio, specifically a split partition gate for cutting off water flow during the expansion and maintenance of a test water pool with a large aspect ratio. Background Art

[0002] Test tanks in the ship field, especially ship towing test tanks, are usually composed of tank structures, guide rail structures, and supporting trailers, workshops, etc. The length-to-width ratio of the tank is generally above 50, which is a test tank with a super-large length-to-width ratio. This type of tank usually has strict requirements on the accuracy of the guide rails, such as the parallelism of two guide rails, and the straightness and flatness of a single guide rail.

[0003] In the actual construction and application of the test pool, in order to maintain a high level of guide rail accuracy, it is necessary to comprehensively consider the impact of various factors on the guide rail, especially the impact of water pressure radiating to the track through the pool structure. Therefore, after the construction of the pool is completed, it is usually necessary to fill it with water and let it stand for dozens of days or even months to release the impact of water pressure on the pool structure, and then adjust the trailer track to eliminate the impact of water pressure on track accuracy as much as possible. After the track adjustment is completed, the water level of the pool should be kept stable as much as possible unless it is absolutely necessary, and it is required that the guide rail should not be adjusted or adjusted as little as possible during the use period, and only necessary fine-tuning should be made to maintain the accuracy and inheritance of the test pool data.

[0004] However, the service life of such large aspect ratio test pools is usually decades or even hundreds of years. Two situations are inevitable during long-term use:

[0005] First, after long-term use, a certain structure of the pool, especially the bottom structure, needs to be repaired;

[0006] Second, with the advancement of technology, ship design has increasingly higher requirements for the accuracy of model test data. The existing water tank length is difficult to meet the requirements of test accuracy in the new era, and it needs to be improved and lengthened to improve test capabilities.

[0007] In response to the above construction requirements, the current common practices are:

[0008] First, the pool is drained for construction, and after construction is completed, water is added and allowed to stand, and then the track accuracy is readjusted;

[0009] The second is to build a temporary dam, that is, to throw a large amount of crushed stones at a certain position at the construction end of the pool to form a dam, lay a geomembrane on the dam and throw a large amount of crushed stones again to compact it, forming a temporary dam for isolating and sealing the pool; after that, the water in the construction section of the pool is drained for construction;

[0010] Thirdly, a reinforced concrete isolation wall similar to the cross-section of the water tank is built outside, and seals are arranged around the isolation wall, and then the isolation wall is hoisted into the cross-section of the water tank for sealing isolation.

[0011] The following problems exist in the above-mentioned sealing and isolation method during the construction of the water tank:

[0012] 1) Full-drainage construction method: The water tank is restricted from being used during the entire construction period and during the track adjustment period after construction. As an extremely scarce ship scientific research and test resource, this construction method causes great waste of resources.

[0013] 2) Temporary dam method: Since the temporary isolation and sealing dam of the water tank is made of gravel and geotextile, the gravel dam cannot be anchored. To resist the influence of the water pressure at the water end of the water tank on the dam, a very long gravel dam needs to be set in the length direction of the water tank. The gravel dam is heavy and is likely to have a destructive impact on the bottom surface of the water tank. Secondly, the geotextile set cannot be completely attached to the bottom surface and the two side facades of the water tank, and it is particularly prone to water leakage. This method is easy to implement, but it is easy to damage the bottom surface of the water tank, the sealing effect is very poor, and it affects the construction operation of the water tank.

[0014] 3) Reinforced concrete isolation wall method: In order to ensure effective sealing, the size of the built isolation wall needs to be larger than the cross-section of the water tank. After construction, the bottom surface and the two side facades of the isolation wall need to be finely polished to generate a good sealing contact surface; the width direction of the isolation wall has relatively strict requirements, with large sizes and it cannot be installed. Or when it is forcibly installed by applying a vertical force, it will cause irreversible damage to the structures of the two side facades of the water tank; with small sizes, it cannot achieve good sealing and is difficult to repair, and a new isolation wall needs to be built. In order to resist the longitudinal water pressure, the isolation wall is usually relatively thick, large in volume and heavy. Inside the water tank factory building with a small construction space and weak crane lifting capacity, the installation, adjustment and demolition operations are all very difficult; one wall is required for each water tank, and the versatility is relatively poor. In this method, it is difficult to control the size of the isolation wall. If it is large, it cannot be installed; if it is small, it is difficult to repair; the sealing surface is difficult to process and has high requirements; the installation and demolition are difficult, and the construction cost is high. Summary of the Invention

[0015] In view of the above-mentioned disadvantages in the existing production technology, the applicant provides a split partition gate device for an ultra-large aspect ratio test water tank, thereby setting a new sealing form. Through the sealing partition of the water tank by the present invention, a dry working environment for the maintenance, repair or lengthening construction of the water tank can be generated without completely draining the water, and it has the advantages of simple structure, light weight, small volume, convenient installation and demolition, low use cost, good sealing effect, good versatility, etc.

[0016] The technical solution adopted by the present invention is as follows:

[0017] A split partition gate device for an ultra-large aspect ratio test pool, including a test pool, in which partition gate devices are installed at intervals. The structure of a single partition gate device is as follows: It includes a cross-pool beam supported on the top surface of the test pool. A split gate is installed in the test pool through a U-shaped seal. A vertical pressing device and a lateral pressing device are installed between the cross-pool beam and the split gate;

[0018] The split gate includes a middle gate, and a first side gate and a second side gate are symmetrically installed at both ends of the middle gate;

[0019] The structure of the cross-pool beam is as follows: It includes floor pedestals fixed on both sides of the test pool. Columns are fixedly arranged on the floor pedestals. A beam body is erected on the two columns. A vertical locking pedestal is fixed on the outer side of the beam body. The structure of the vertical locking pedestal is as follows: It includes a pedestal structure. A guide ring is fixed on the lower side of the pedestal structure. A nut structure is fixed at the pedestal structure above the fixed guide ring. T-shaped screw pedestals are also fixed on the outer sides of the beam body on both sides of the pedestal structure;

[0020] A plurality of vertical pressing devices are arranged at intervals on the top surface of the split gate. The structure of a single vertical pressing device is as follows: It includes a connecting pedestal fixed on the top surface of the split gate. A vertical push rod is fixedly connected to the connecting pedestal. The upper part of the vertical push rod passes through the guide ring. The top surface of the vertical push rod is connected to the bottom of the push rod screw, and at the same time, the push rod screw passes through the nut structure;

[0021] The lateral pressing device includes a screw jack, a long horizontal push rod, a short horizontal push rod and a T-shaped screw. The long horizontal push rod and the short horizontal push rod are respectively arranged at the left and right ends of the screw jack and supported on the split gate. The T-shaped screw penetrates through the upper and lower ends of the screw jack and is threadedly connected to the top node of the screw jack. The opening and closing of the screw jack are realized through threaded rotation movement, and the long horizontal push rod and the short horizontal push rod are driven to press the two side gates; The T-shaped screw extends upward to the beam body and passes through the T-shaped screw pedestal.

[0022] Its further technical solution lies in:

[0023] In the test pool, during the maintenance and repair working conditions, two adjacent partition gates are installed opposite to each other.

[0024] In the test pool, during the water isolation and sealing blocking working conditions, a single partition gate device can be used.

[0025] The structures of the first side gate and the second side gate are the same.

[0026] The structure of the No. 1 side gate is as follows: It includes a reinforced gate panel, a gate elbow plate, an F-shaped side plate, and a horizontal guide. One side of the reinforced gate panel is the reinforced surface, and the gate elbow plates are arranged at intervals. The other side of the reinforced gate panel is the water pressure-receiving surface; on one side of the reinforced gate panel where it is connected to the middle gate, there is an F-shaped side plate, and an installation groove is provided on the F-shaped side plate for the installation, fixation, and sealing of the middle gate; on the back water surface side of the reinforced gate panel, there is a horizontal guide for installing the lateral pressing device. A long horizontal push rod and a short horizontal push rod pass through the horizontal guide, and at the same time, the long horizontal push rod and the short horizontal push rod abut against the F-shaped side plate.

[0027] A circle of panels perpendicular to the plate is arranged around the periphery of the reinforced gate panel.

[0028] The gate elbow plate is of a trapezoidal structure, and a plurality of round holes are opened on the gate elbow plate.

[0029] The middle gate includes a middle gate plate and a groove-shaped seal. The groove-shaped seal is composed of a horizontally arranged sealing piece and two vertically arranged sealing pieces. The two vertically arranged sealing pieces are attached to both sides of the middle gate plate, and the horizontal sealing piece is arranged between the bottom panel of the middle gate plate and the U-shaped seal.

[0030] The groove-shaped seal is of an integral structure.

[0031] The U-shaped seal is composed of stacked hard rubber seals and soft rubber seals.

[0032] The beneficial effects of the present invention are as follows:

[0033] The structure of the present invention is compact and reasonable, and the operation is convenient. The partition of the water pool is realized through the split gate. The gate and the seal are pressed against the bottom of the water pool through the vertical pressing device to achieve the bottom seal. Through the lateral pressing device, the two side gates and the seal are pressed against the vertical surface of the water pool to achieve the seal of the two side vertical surfaces. Through the increase in water pressure during the drainage process, the middle gate is pressed against the side gate to achieve the seal between the middle gate and the side gate. Through the seal partition of the water pool by the present invention, a dry operation environment for the maintenance and repair of the water pool or the extension of the construction can be generated without completely draining the water, and it has the advantages of simple structure, light weight, small volume, convenient installation and removal, low use cost, good sealing effect, and good versatility.

[0034] At the same time, the present invention also has the following advantages:

[0035] 1) Compared with the full-empty construction method, the present invention can achieve isolation and sealing only for the construction section of the water tank. For maintenance operations, only the water in the maintenance section needs to be emptied, which has little impact on the track accuracy and can effectively reduce the idle time of the water tank during the maintenance construction period; for lengthening construction, only the water at the end of the lengthening section needs to be emptied, without affecting the use of the original water tank during the lengthening construction. The present invention can effectively reduce the idle time during the water tank construction period and reduce the waste of water tank resources.

[0036] 2) Compared with the temporary dam construction method, the present invention has a light overall weight, a small scale in the length direction of the water tank, a flat and smooth bottom panel, and the installation operation will not cause destructive impact on the water tank floor; it has little impact on the water level of the water tank and can effectively reduce the impact of water level changes on the track accuracy. The seal is pressed against the water tank floor and both side facades through vertical and lateral pressing devices, and the sealing effect is good. The present invention can effectively improve the isolation and sealing efficiency of the water tank, reduce the impact of isolation and sealing construction on the track accuracy of the water tank, eliminate the impact of poor sealing on construction, improve construction efficiency and quality, and shorten the construction period.

[0037] 3) Compared with the isolation wall construction method, the present invention is a split structure with a light overall weight and an even lighter weight of a single gate. In a water tank plant with a small space and insufficient lifting capacity, it is relatively easy to install, adjust and disassemble the gate with the help of the lifting equipment in the plant; by adjusting the width of the middle gate, the water tanks with different widths within the effective width range can be partitioned and sealed, and the versatility is relatively good, and it can be used as a common equipment configuration for a series of water tanks with a long construction age; for the split gate, the sealing of both side facades of the water tank is achieved through the lateral pressing device in the width direction, and the sealing pressing force is controllable and adjustable, without causing destructive impact on the water tank structure; the sealing requirements for both sides and the bottom panel are relatively easy to achieve, and it has the advantages of convenient processing, low manufacturing difficulty and low use cost.

[0068] In the test pool, during the maintenance and repair working conditions, two adjacent partition gates are installed oppositely.

[0069] In the test pool, during the water isolation and sealing interruption working conditions, a single partition gate device can be used.

[0070] The structures of the first side gate 101 and the second side gate 103 are the same.

[0071] The structure of the first side gate 101 is as follows: It includes a stiffened gate panel 1011, a gate elbow plate 1012, an F-shaped side plate 1013, and a horizontal guide 1014. One side of the stiffened gate panel 1011 is the stiffened surface, and the gate elbow plates 1012 are arranged at intervals.

[0072] A circle of panels perpendicular to the plate is arranged around the periphery of the stiffened gate panel 1011.

[0073] The gate elbow plate 1012 is of a trapezoidal structure, and a plurality of round holes are opened on the gate elbow plate 1012.

[0074] The middle gate 102 includes a middle gate plate 1021 and a groove-shaped seal 1022. The groove-shaped seal 1022 is composed of a horizontally arranged sealing piece and two vertically arranged sealing pieces. The two vertically arranged sealing pieces are attached to both sides of the middle gate plate 1021, and the horizontally arranged sealing piece is arranged between the bottom panel of the middle gate plate 1021 and the U-shaped seal 5; both sides of the middle gate plate 1021 are symmetrically and sealingly installed in the installation groove 1015 on the F-shaped side plate 1013.

[0075] The groove-shaped seal 1022 is of an integral structure.

[0076] The U-shaped seal 5 is composed of stacked hard rubber seals 501 and soft rubber seals 502.

[0077] The specific structure and function of the present invention are as follows:

[0078] The split gate is mainly composed of a first side gate 101, a middle gate 102, and a second side gate 103, as Figure 2 and Figure 3 shown.

[0079] Among them: The first side gate 101 is mainly composed of a stiffened gate panel 1011, a gate elbow plate 1012, an F-shaped side plate 1013, and a horizontal guide 1014, as Figure 3The stiffened gate panel 1011 is a plate structure with stiffeners on one side, and a panel perpendicular to the plate is arranged around the periphery. The gate gusset 1012 is arranged on the side of the gate panel with stiffeners. When water pressure acts on the other side of the stiffened gate panel 1011, it supports the stiffened gate panel 1011 in an upright state. The F-shaped side plate 1013 is arranged on one side of the stiffened gate panel 1011 connecting to the middle gate 102, and forms an installation groove 1015 for the installation, fixation and sealing of the middle gate 102. The horizontal guide 1014 is arranged on the back water side of the stiffened gate panel 1011 for guiding and supporting the push rod of the lateral pressing device 3, as Figure 7 shown.

[0080] Among them, the middle gate 102 is mainly composed of a middle gate plate 1021 and a groove-shaped seal 1022. The groove-shaped seal 1022 is a rubber seal with a U-shaped projection perpendicular to the gate and an L-shaped projection perpendicular to the vertical plane. It is mainly composed of two vertically arranged sealing sheets and one horizontally arranged sealing sheet, as Figure 4 shown; the two vertically arranged sealing sheets are attached to both sides of the middle gate plate 1021, and the bottom horizontal sealing sheet is arranged between the bottom panel of the middle gate plate 1021 and the U-shaped seal 5; the middle gate plate 1021 is inserted into the installation groove 1015 of the F-shaped side plate 1013 on both side gates, and the bottom sits on the horizontal sealing sheet of the groove-shaped seal 1022, and is sealed with the plane of the F-shaped side plate 1013 through the vertically arranged sealing sheet of the groove-shaped seal 1022, as Figure 4 , Figure 5 and Figure 8 shown. The structural shape of the second side gate 103 is symmetrically arranged with that of the first side gate 101, and will not be elaborated here.

[0081] The vertical pressing device 2 is mainly composed of a vertical push rod 201, a push rod screw 202 and a connecting base 203, which is mainly used to press the gate and the U-shaped seal 5 onto the bottom surface T1 of the pool to ensure the seal between the gate and the bottom surface of the pool, as Figure 2 , Figure 3 and Figure 6 shown. Among them, the connecting base 203 is respectively fixedly arranged on the top panel of the gate, and the specific quantity is determined according to the width of the gate; for the convenience of describing the present invention, two connecting bases 203 are arranged on the top panel of each gate; the shape of the base is determined according to the shape of the vertical push rod 201. The bottom foot of the vertical push rod 201 is connected to the connecting base 203, and the top extends to the guide ring 4043 and is connected to the push rod screw 202; the push rod screw 202 is arranged on the vertical locking base 404 and is connected with the nut structure 4042 to form a screw motion pair, and the vertical push rod 201 is forced and locked through the screw-nut connection.

[0082] The lateral pressing device 3 is mainly composed of a screw jack 301, a long horizontal push rod 302, a short horizontal push rod 303 and a T-shaped screw rod 304, as Figure 6 and Figure 7 shown. The lateral pressing device 3 is mainly used to press the first side gate 101, the second side gate 103 and the U-shaped seal 5 against the side vertical surface T2 of the pool to achieve the sealing of the side vertical surface. The screw jack 301 is a conventional screw force application mechanism; the long horizontal push rod 302 and the short horizontal push rod 303 are respectively arranged at the left and right ends of the screw jack 301 and pass through the horizontal guide 1014 to abut against the F-shaped side plate 1013. The T-shaped screw rod 304 passes through the upper and lower ends of the screw jack 301 and is threadedly connected to the top node of the screw jack 301. The opening and closing of the screw jack 301 are realized through the rotational movement of the thread, driving the long horizontal push rod 302 and the short horizontal push rod 303 to press the two side gates against the pool vertical surface. The T-shaped screw rod 304 extends upward to the crossbeam body 403 and is constrained by the screw guide arranged outside the crossbeam body 403.

[0083] The number of the lateral pressing devices 3 is determined by the depth of the pool. If the pool depth is relatively shallow, one set is sufficient; when the pool is deeper, multiple sets are required; in the present invention, two sets are set according to the pool depth, and the T-shaped screw rods 304 are staggered through the settings of the long horizontal push rod 302 and the short horizontal push rod 303.

[0084] The cross-pool crossbeam 4 is composed of a floor base 401, columns 402, a crossbeam body 403, a screw base and a screw guide, and mainly provides a foundation for other structures of the present invention, as Figure 2 and Figure 3 shown. Among them, the floor bases 401 are fixedly and symmetrically arranged on the foundations on both sides of the pool, the columns 402 are fixed on the floor bases 401, and the crossbeam body 403 is erected on the columns 402 on both sides to form an inverted U-shaped crossbeam structure. The crossbeam body 403 can be used for personnel passage and operation. The screw base is installed on the side of the crossbeam body 403 and is mainly composed of a base structure 4041, a nut structure 4042 and a guide ring 4043; among them, the base structure 4041 is fixed on the side of the crossbeam body 403, and the number is determined by the number of the vertical pressing devices 2; the nut structure 4042 is fixed on the lower side of the horizontal panel of the base structure 4041 and forms a threaded nut connection structure with the push rod screw 202 to realize the force application and locking of the push rod screw 202. The guide ring 4043 is arranged on the base structure 4041 and below the nut structure 4042, and the vertical push rod 201 passes through the middle to play the roles of upper and lower guiding and constraint.

[0085] The U-shaped seal 5 is mainly composed of a hard rubber seal 501 and a soft rubber seal 502, and is arranged at the corresponding positions of the first side gate 101, the middle gate 102, the second side gate 103 and the bottom surface of the pool facade, so as to realize the seal between the gate and the pool facade and the bottom surface, as Figure 8 shown. Among them, the hard rubber seal 501 is a seal made of ordinary rubber sheets, and is arranged between the gate panel and the soft rubber seal 502. Through extrusion deformation, a seal is formed between the relatively flat gate panel and the soft rubber seal 502. The soft rubber seal 502 is made of soft rubber or other suitable soft materials that can produce large compression deformation after extrusion, and is arranged between the hard rubber seal 501 and the pool facade and the bottom surface. After being pressed, it deforms greatly and can seal the relatively uneven pool facade and the bottom surface.

[0086] During the actual working process:

[0087] The present invention is mainly used for water isolation and maintenance during the maintenance and repair of the test pool or the extension construction, so as to form a dry construction environment. The following will be combined with Figure 10 and Figure 9 , to illustrate the specific implementation manner of the present invention. There are mainly two relatively typical applications of the present invention. The implementation of the present invention will be described below with these two typical application scenarios.

[0088] (1) Application and implementation of the present invention in the extension of the test pool:

[0089] The application and implementation of the present invention in the extension construction of the pool are as Figure 10 shown. The extension section of the pool has completed the engineering construction, and the extension section needs to be combined with the original pool for construction. Among them, T1 is the bottom of the original pool, and T1-1 is the bottom of the extension section; T2 is the two side facades of the original pool, and T2-1 is the two side facades of the extension section; T3 is the facade at the extended end of the original pool in the length direction, as Figure 10 shown; during the construction, it is necessary to remove T3, and combine the construction of T1 and T1-1, and combine the construction of T2 and T2-1. In order to ensure that the original pool can still be used during the combined construction with the extension section and avoid waste of resources, it is necessary to isolate and seal the water in the pool at the extended end of the original pool.

[0090] First, fixedly set the floor pedestals 401 at a certain distance from the construction facade T3 on both sides of the extended end of the pool, and install the columns 402 on the floor pedestals. Then, install the crossbeam body 403 on the columns 402 to form a foundation for installing other structures.

[0091] Then, install a split gate and a lateral pressing device 3 outside the water tank. Place the first side gate 101 and the second side gate 103 symmetrically, lay the grooved seal 1022 on the intermediate gate plate 1021, and insert the installed intermediate gate 102 into the installation groove 1015 of the F-shaped side plate 1013 opposite to the first side gate 101 and the second side gate 103 to form a split gate. Then, lay the U-shaped seal 5 on the bottom and both side panels of the split gate, as Figure 2 shown; fix the connection bases 203 of the vertical pressing device 2 on the upper side panels of the split gate respectively, as Figure 3 and Figure 5 shown. To ensure that the width of the gate is slightly smaller than the width of the water tank, when installing the split gate, ensure that the first side gate 101, the second side gate 103 and the intermediate gate 102 are in a compressed state in the width direction. After that, install the long horizontal push rod 302 and the short horizontal push rod 303 at the left and right ends of the screw jack 301, and pass the T-shaped screw rod 304 through the upper and lower ends of the screw jack 301 to form a lateral pressing device 3; pass the long horizontal push rod 302 and the short horizontal push rod 303 in the two installed lateral pressing devices 3 into the guide holes of the corresponding horizontal guides 1014 on the first side gate 101 and the second side gate 103 respectively, and they are in a relaxed state. Finally, use the lifting equipment in the water tank workshop to arrange the installed split gate into the water tank. When placing, the side with the gate elbow plate 1012 faces the side that needs to drain water, as Figure 10 shown, the side facing the elevation T3; at the same time, pass the T-shaped screw rod 304 through the T-shaped screw rod base 405 so that the operating part of the T-shaped screw rod 304 extends to the crossbeam body 403 for easy operation by personnel.

[0092] After that, with the assistance of the lifting equipment, install the bottom feet of the vertical push rod 201 on the connection base 203, and the upper part passes through the guide ring 4043 and extends below the nut structure 4042. Pass the push rod screw 202 through the hole on the base structure 4041, rotate and screw it into the nut structure 4042, and extend downward out of the nut structure 4042 to top into the pressing hole on the upper part of the vertical push rod 201.

[0093] The above operations complete the installation of the basic structure of the present invention. After that, personnel enter onto the crossbeam body 403 and respectively and successively rotate the T-shaped screw rod 304 and the vertical push rod 201 directly or by using tools. Rotating the T-shaped screw rod 304 drives the screw jack 301 to compress in the vertical direction and expand in the horizontal direction, driving the long horizontal push rod 302 and the short horizontal push rod 303 to move towards the side gates on both sides, and pressing the side gates to move towards the two side vertical surfaces of the pool; the side gates are pressed to move towards both sides, squeezing the hard rubber seal 501 and the soft rubber seal 502, causing them to deform and fill the gap between the side panel of the side gate and the side vertical surface T2 of the pool, forming a seal. Rotating the push rod screw 202, under the action of the nut structure 4042, a downward thrust is formed, and the thrust is transmitted to the upper panel of the gate through the vertical push rod 201 and the connecting base 203; under the action of the thrust, the side gates squeeze the hard rubber seal 501 and the soft rubber seal 502 downward, causing them to deform and fill the gap between the bottom panel of the side gate and the bottom surface of the pool; the middle gate 102 squeezes the horizontal sealing piece at the bottom of the groove-shaped seal 1022, the hard rubber seal 501 and the soft rubber seal 502 downward, causing them to deform and fill the gap between the bottom panel of the middle gate 102 and the bottom surface T1 of the pool; a watertight seal is formed between the bottom panel of the gate and the bottom surface of the pool.

[0094] After that, use a water pump to pump out the water between the present invention and the vertical surface T3. As the water level drops, the water on the other side in the pool generates water pressure on the gate. The gate toggle 1012 supports the side gate to resist the water pressure, and the F-shaped side plate 1013 of the side gate supports the middle gate 102 to resist the water pressure; at the same time, under the action of the water pressure, the compressed middle gate plate 1021 presses the sealing pieces on both sides of the groove-shaped seal 1022 against the F-shaped side plate 1013, forming a seal between the middle gate 102 and the two side gates along the depth direction of the pool, as Figure 5 and Figure 8 shown. After the water is pumped out, a dry construction environment is formed, and the demolition of the T3 vertical surface and the joint construction between T1 and T1-1, T2 and T2-1 are carried out, without affecting the use of the original test pool at the same time. After the joint construction of the pool structure is completed, the pool from the present invention to the extended section can be filled with water and left standing to release the influence of water pressure on the structure, without affecting the use of the original pool. After the structural stress of the extended section and the joint section is released, loosen the vertical pressing device 2 and the lateral pressing device 3, and remove the relevant structures of the present invention, which basically has no impact on the original pool structure and greatly reduces the idle time of the original pool.

[0095] (2) Application and implementation of the present invention in the maintenance of the test pool:

[0096] As Figure 9As shown, the installation method and sealing operation of the present invention are the same as those described above. When repairing a certain section of the pool, two sets of the present invention are required and are symmetrically arranged, that is, when installing the split gate, the elbows 1012 of the gate are all facing the pool section to be repaired.

[0097] After the installation and related sealing operations of the present invention are completed, use a water pump to drain the water in the maintenance section between the installations of the present invention and discharge the water into the pool at the other end of the present invention. Under the action of the two sets of the present invention, a dry pool maintenance environment is formed. After the pool maintenance is completed, first fill the dry space in the middle of the present invention with water. After the water is full, then remove the present invention to restore the pool test state. Since only the local drainage operation of the pool is carried out, the technical state of the track is basically not affected; if necessary, fine-tuning of the track can meet the requirements.

[0098] Through the present invention, the sealing isolation of the operation section during the repair or lengthening of the ultra-large aspect ratio test pool is realized, and a dry construction environment for pool maintenance, repair or lengthening is formed without emptying all the water.

[0099] Through the present invention, the operation section can be isolated and sealed with little impact on the water level of the pool, forming a dry construction environment. For maintenance operations, only the water in the maintenance section needs to be drained, which has little impact on the track accuracy and can effectively reduce the idle time of the pool during the maintenance construction period; for lengthening construction, only the water in the isolation section at the lengthening end needs to be drained, without affecting the use of the original pool during the lengthening construction. The application of the present invention can effectively reduce the impact of maintenance construction on the track accuracy, avoid the idle time of the pool during the combined construction of the lengthening section, and effectively reduce the waste of pool resources caused by construction operations.

[0100] The single gate and the overall weight of the present invention are relatively light. In a pool workshop with a narrow space, the installation, adjustment and removal operations can be conveniently completed with the help of an internal traveling crane or other lifting tools; the bottom panel is flat and smooth, and will not cause destructive impact on the pool floor; the dimension along the length direction of the pool is small and the overall volume is small. The installation and removal have little impact on the pool water level, effectively reducing the impact of water level change on the track accuracy.

[0101] The present invention is of a split structure and is adjustable in width direction. By controlling the width of the middle gate 102, the lateral isolation and sealing of pools with different widths within the effective width are realized, and the versatility is relatively good, which can be used as a common equipment configuration for some pools with a long construction age.

[0102] The bottom and side sealing surfaces of the gate in the present invention are easy to be processed into planes that meet the sealing requirements, and the vertical and lateral pressing devices are used to realize the pressing and sealing with the bottom surface and the two side vertical surfaces of the pool. The sealing operation is convenient and the sealing effect is good; in addition, the sealing pressing force is controllable and adjustable, and it is not easy to cause destructive impact on the pool structure.

[0103] The present invention has the advantages of simple structure, easy processing and manufacturing, small volume, light weight, simple and convenient installation and removal, good versatility, low use cost, and good sealing effect.

[0104] The above description is an explanation of the present invention, not a limitation thereof. The scope defined by the present invention is referred to the claims, and any form of modification can be made within the protection scope of the present invention.
