Description

Technical Field

[0001] The present invention relates to the technical field of bridge seepage detection, and particularly to a bridge seepage detection device for the A ramp over-railway swivel bridge. Background Art

[0002] The over-railway swivel bridge is a special bridge structure that uses the swivel construction method to cross the railway line. A swivel bridge, that is, a bridge constructed by the swivel method, refers to a construction method in which the bridge structure is fabricated at a non-designed axis position and then put in place by swiveling. It can convert the operation over obstacles into an operation on the shore or near the ground, and is mainly applied to situations where it is impossible to make supports over valleys, rivers, railways, highways, etc. After the bridge is produced, it is necessary to detect the permeability of its bridge deck to ensure the driving safety of the bridge in rainy days or when there is accumulated water.

[0003] In the prior art, this device is fixed on the test ground through a limit adjustment device, and the sealing performance is adjusted in combination with a pressure device, which is beneficial to improving the accuracy of the seepage test. At the same time, multiple cavities are adopted inside the detection sleeve, and multiple groups of seepage data can be obtained simultaneously, which is beneficial to forming a data difference to judge the seepage degree and can greatly improve the work efficiency. However, during the use process, the water in the cavity of the detection sleeve only acts on the ground by its own gravity, so that the water seeps into the ground to detect the seepage effect of the bridge. Simply relying on the gravity of the water acting on the ground to apply pressure, the detection efficiency is low. For example, a bridge seepage detection device for bridge detection provided in the authorized announcement number CN114544087B drills a foundation pit evenly in a ring shape on the test ground, screws the lower ends of several bolt rods evenly in a ring shape with threads, passes the through holes on the base through the upper ends of the bolt rods, and fixes the base by the installed several bolt rods. At the same time, the rubber ring at the bottom end of the detection sleeve inside the base contacts the ground. A limit adjustment device is sleeved on the top end of the bolt rod on the upper end of the base, and the limit block on one side of the limit adjustment device is embedded in the limit groove. By screwing the adjustment nut, the limit adjustment device descends on the bolt rod, and finally the bottom end of the base contacts the ground. At the same time, the pressure spring connected to the top end of the inner movable groove is compressed, so that the detection sleeve generates a downward pressure, and the rubber ring at the bottom end of the detection sleeve is squeezed and deformed to fit the test ground more closely. Water is injected into the two cavities inside it through the water inlet pipe at the top end of the detection sleeve, and the seepage data can be collected by observing the change of the water level scale. Two groups of data can form a comparison.

[0004] It has great drawbacks: during the use process, the water in the cavity of the detection sleeve only acts on the ground by its own gravity, so that the water seeps into the ground to detect the seepage effect of the bridge. Simply relying on the gravity of the water acting on the ground to apply pressure, the detection efficiency is low. Summary of the Invention

[0005] In an embodiment of the present application, by providing a bridge water seepage detection device for the A ramp over-railway swivel bridge, the problem in the prior art during use is solved. That is, the water in the cavity of the detection sleeve only acts on the ground by its own gravity, causing the water to seep into the ground. When detecting the water seepage effect of the bridge, simply relying on the gravity of the water acting on the ground to apply pressure results in low detection efficiency. By changing the shape of the bottom side of the measuring cylinder, the weight of the water itself can be used to improve the detection efficiency and reduce the detection time. By adding the aggregation cylinder, the contact area between the water and the ground is reduced. For the same volume of water, the pressure acting on the bridge surface in the water storage tank will increase. With the increase in pressure, the water seepage efficiency on the bridge surface becomes higher, and the detection efficiency is improved.

[0044] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0045] First, by changing the shape of the bottom of the measuring tube, the weight of the water itself can be used to improve detection efficiency and reduce detection time. By adding a collection tube, the contact area between the water and the ground is reduced. The pressure exerted on the bridge deck by the same volume of water in the water storage tank will increase. The higher the pressure, the more efficient the water seepage on the bridge deck, and the higher the detection efficiency.

[0046] Secondly, it can flexibly adjust the water seepage pressure. By inflating or deflating the air-filled space to flexibly adjust the water pressure inside the gathering tube, it can simulate water seepage conditions under different pressures, and can more accurately simulate and measure the water seepage conditions of the bridge deck under high-pressure water flow, thereby more comprehensively evaluating the water seepage performance of the bridge; improve water seepage efficiency. When the air-filled space is inflated, the water in the lower part of the cavity separated by the expansion of the gathering tube will be squeezed, increasing the pressure of the water on the ground, which can not only improve the water seepage efficiency, but also more quickly observe the water seepage situation; it can apply pressure to the water; and simulate real scenes. By inflating or deflating the air-filled space, it can imitate the conditions of the bridge when it is subjected to extreme weather such as heavy rain or flooding.

[0047] Thirdly, by adding electromagnets, the sides of the two electromagnets close to each other attract each other, which can divide the water in the water storage tank and the aggregation cylinder into upper and lower parts. When squeezing the water below the water storage tank during the inflation process, the sealing performance is improved, increasing the water seepage efficiency when squeezing the water in the cavity below the electromagnet. When the sides of the two electromagnets close to each other repel each other, under the action of the gravity of the water, it can impact on the water in the lower part, forming a certain impact force. The impact force can act on the water in the cavity below the electromagnet and the ground, accelerating the water seepage efficiency;

[0048] Fourthly, the added baffle can, during the use of the device, increase the force generated by the water above the electromagnet impacting the water below the electromagnet, thereby increasing the generated impact force. At the same time, during the inflation and deflation of the inflation space, the baffle can also increase the speed of disturbing the internal water flow and the speed of the water sloshing inside, thus imitating the state of water when a car drives over a puddle at high speed.

[0068] Drill holes on the test bridge deck. Place the fixing base 110 on the bridge deck to be tested and fix it in the hole of the bridge deck through the fixing bolt 120 passing through the fixing hole 112, so as to fix the whole device on the bridge deck to be tested. Inject the same volume of water into the two water storage tanks 211 through the water delivery pipe 220. After that, the water delivery pipe 220 is in a state of communicating with the water storage tanks 211, and the water is stored in the aggregation cylinder 310 of the measuring cylinder 210. It gradually seeps into the bridge deck through the opening at the lower end of the aggregation cylinder 310. During the seepage process, manually record the seepage time and the change of the water level in the water storage tank 211. Obtain the data required for detection by observing the time required for the two water storage tanks 211 to seep water. Compare the time required for the two water storage tanks 211 to seep water to judge the water seepage volume in different areas of the bridge deck.

[0069] Embodiment 1: As Figures 1-2 shown, a bridge water seepage detection device for the A ramp over-railway turning bridge of the present application includes a fixing component 100 and a storage component 200;

[0070] The fixing component 100 includes a fixing base 110. The fixing base 110 is a cylindrical shape with an open upper end, and the axis of the fixing base 110 is perpendicular to the bridge deck to be detected;

[0071] The storage component 200 further includes a measuring cylinder 210 and a water storage tank 211;

[0072] The measuring cylinder 210 is cylindrical, the axis of the measuring cylinder 210 is on the same straight line as the axis of the fixing base 110, and the measuring cylinder 210 is fixed in the fixing base 110;

[0073] The bottom side of the measuring cylinder 210 is provided with a water storage tank 211. The water storage tank 211 is cylindrical, and the axis of the water storage tank 211 is parallel to the axis of the fixing base 110;

[0074] There are two water storage tanks 211, which are symmetrically arranged;

[0075] It further includes an impact component 300. There are two impact components 300, which correspond to the two water storage tanks 211 one by one. The impact component 300 includes an aggregation cylinder 310;

[0076] The aggregation cylinder 310 is a frustum-shaped cylinder with a through upper and lower part. The axis of the aggregation cylinder 310 is on the same straight line as the straight line of the water storage tank 211. The aggregation cylinder 310 is located in the water storage tank 211, and the end with the larger outer diameter of the aggregation cylinder 310 is fixed on the inner wall of the water storage tank 211;

[0077] The lowermost end of the aggregation cylinder 310 is on the same horizontal plane as the lowermost end of the measuring cylinder 210, and the lower side of the aggregation cylinder 310 is made of rubber material;

[0078] The fixed component 100 further includes a through port 111, fixing holes 112 and fixing bolts 120;

[0079] The inner bottom side of the opening of the fixed component 100 is provided with the through port 111 and the fixing holes 112;

[0080] The through port 111 is cylindrical, the axis of the through port 111 is on the same straight line as the axis of the fixed seat 110, the measuring cylinder 210 is fixed in the through port 111, and the lower side surface of the measuring cylinder 210 is on the same horizontal plane as the lower side surface of the fixed seat 110;

[0081] There are multiple fixing holes 112, and the fixing holes 112 are evenly distributed at intervals in a ring around the through port 111;

[0082] The number of the fixing bolts 120 is the same as the number of the fixing holes 112, and the fixing bolts 120 are threadedly connected in the fixing holes 112;

[0083] The measuring cylinder 210 is made of transparent plastic steel material, and the side wall of the measuring cylinder 210 is provided with a scale table;

[0084] The lower end of the measuring cylinder 210 is made of rubber material;

[0085] The storage component 200 further includes a water delivery pipe 220;

[0086] The number of the water delivery pipes 220 is the same as the number of the water storage tanks 211 and they correspond one by one. The water delivery pipes 220 are fixed on the measuring cylinder 210 and the water delivery pipes 220 are communicated with the water storage tanks 211.

[0087] When in use, drill holes in the test bridge surface, place the fixed seat 110 on the test bridge surface to be tested, fix it in the holes on the bridge surface through the fixing bolts 120 passing through the fixing holes 112, fix the whole device on the test bridge surface to be tested, inject the same volume of water into the two water storage tanks 211 through the water delivery pipes 220. After that, the water delivery pipes 220 are in a state of communicating with the water storage tanks 211, and the water is stored in the collecting cylinder 310 of the measuring cylinder 210 and gradually seeps into the bridge surface through the opening at the lower end of the collecting cylinder 310. During the seepage process, manually record the seepage time and the change of the water level in the water storage tanks 211, obtain the data required for detection by observing the seepage time required for the two water storage tanks 211, and compare the seepage time required for the two water storage tanks 211 to judge the water seepage volume in different areas of the bridge surface.

[0088] Compared with the prior art, by changing the shape of the inner bottom side of the measuring cylinder 210, the detection efficiency can be improved and the detection time can be reduced by the weight of the water itself. With the addition of the aggregation cylinder 310, the contact area between the water and the ground is reduced. For the same volume of water, the pressure acting on the bridge surface in the water storage tank 211 will increase. As the pressure increases, the water seepage efficiency on the bridge surface becomes higher, and the detection efficiency is improved.

[0089] Embodiment 2: When Embodiment 1 is in use, only the gravity of the water itself can provide the pressure required to penetrate into the bridge surface, and it takes a relatively long time to obtain the detection data completely. During the detection process, only the seepage effect of the water on the bridge surface in a static state can be detected, and the data of the impact force generated by the rainwater falling on a rainy day cannot be obtained. The data obtained by the detection is not accurate. Therefore, the solution of Embodiment 1 is improved as follows Figures 3-5 as shown:

[0090] The aggregation cylinder 310 is made of rubber material;

[0091] The impact component 300 includes a fixed cover 320, a fixed port 321 and an air pump 330;

[0092] The fixed cover 320 is cylindrical, and the axis of the fixed cover 320 is on the same straight line as the axis of the water storage tank 211;

[0093] The outer wall of the fixed cover 320 is fixed on the inner bottom side of the water storage tank 211, and the lower side surface of the fixed cover 320 is on the same horizontal plane as the lower side surface of the measuring cylinder 210;

[0094] The fixed cover 320 is provided with a fixed port 321, the fixed port 321 is frustum-shaped, and the axis of the fixed port 321 is on the same straight line as the axis of the fixed cover 320;

[0095] The lower end side wall of the aggregation cylinder 310 is fixed on the lower end inner wall of the fixed port 321;

[0096] The outer wall of the aggregation cylinder 310, the upper side surface of the fixed cover 320 and the inner wall of the water storage tank 211 form an inflation space;

[0097] The air pump 330 is fixed above the measuring cylinder 210, the output end of the air pump 330 is communicated with the inflation space, and the air pump 330 can pump air.

[0098] When detecting the bridge, after the water in the water storage tank 211 is drained and filled, the inflation space can be inflated by the air pump 330. During the inflation and expansion process, the rubber material aggregation cylinder 310 will deform, squeezing the water stored inside. During the deformation process of the aggregation cylinder 310, the inner walls of the aggregation cylinder 310 will come into contact with each other, dividing the internal cavity into upper and lower parts. Then, when continuing to inflate the inflation space, the water in the lower part of the cavity of the aggregation cylinder 310 will be squeezed, applying pressure to the water so that the water seeps into the bridge deck. After expanding to a certain extent, the gas in the inflation space is deflated. During the inflation and deflation process, the internal water can be disturbed to make the water shake, mimicking the state of a car driving over a puddle. After deflating, inflate again and work in this way repeatedly; during the deflation process, due to the expansion of the aggregation cylinder 310, the height of the water can be lifted. During the deflation process, the water above the cavity of the aggregation cylinder 310 falls onto the water below the cavity of the aggregation cylinder 310, mimicking the state of rain falling on the bridge deck during rainfall, providing the pressure of water acting on the ground.

[0099] Flexibly adjust the seepage pressure. By inflating or deflating the inflation space, the water pressure inside the aggregation cylinder 310 can be flexibly adjusted, and the seepage conditions under different pressures can be simulated, enabling more accurate simulation and measurement of the seepage conditions of the bridge deck under high-pressure water flow, thereby more comprehensively evaluating the seepage performance of the bridge; improve the seepage efficiency. When inflating the inflation space, the water in the lower part of the cavity separated by the expansion of the aggregation cylinder 310 will be squeezed, increasing the pressure of the water acting on the ground, which can not only improve the seepage efficiency but also more quickly observe the seepage situation; the water can be pressured; simulate the real scene. By inflating or deflating the inflation space, the situation of the bridge under extreme weather such as heavy rainfall or flood can be mimicked.

[0100] Example 3: When Example 2 is in use, by inflating and deflating the inflation space, the pressure on the water in the aggregation cylinder 310 is changed. During the process of filling the gas in the inflation space and then releasing the gas, the gas gradually decreases. During the gradual decrease process, the force supporting the water in the upper part of the cavity separated by the expansion of the aggregation cylinder 310 gradually decreases, and the water will squeeze open the mutually attached parts of the aggregation cylinder 310. The water above the cavity of the aggregation cylinder 310 gradually falls onto the water below the cavity of the aggregation cylinder 310, generating a relatively small impact force. At the same time, when continuing to squeeze the water in the lower part of the cavity of the aggregation cylinder 310 after the aggregation cylinder 310 is attached, the pressure will squeeze open the attachment part of the aggregation cylinder 310. Based on this, the solution of Example 2 is improved as Figures 6-9 shown:

[0101] The impact component 300 further includes an electromagnet 340;

[0102] There are two electromagnets 340, which are symmetrically fixed on both sides of the aggregation cylinder 310. The length direction of the electromagnet 340 is parallel to the ground, and the length directions of the two electromagnets 340 are parallel to each other.

[0103] The electromagnet 340 is a DC electromagnet.

[0104] The mutually approaching sides of the two electromagnets 340 repel each other and are opened together with the gas pumped out of the inflation space by the air pump 330. When the two electromagnets 340 repel and squeeze the gas in the inflation space and the air pump 330 extracts the gas in the inflation space and exhausts the gas at the same time, the gas in the inflation space can be completely exhausted within two seconds.

[0105] Water is stored in the water storage tank 211. After the water contacts the bridge deck, the air pump 330 inflates the inflation space. During the inflation and expansion process, the water stored inside is squeezed. During the squeezing process, the water can exert pressure on the ground in contact, so that the water seeps into the bridge deck. After expanding to a certain extent, the two electromagnets 340 attract each other, dividing the water in the water storage tank 211 and the aggregation cylinder 310 into upper and lower parts. The air pump 330 stops inflating. The mutually approaching sides of the electromagnets 340 repel each other and the air pump 330 extracts the gas in the inflation space at the same time. The water above the electromagnet 340 loses support, and the height of the water above the electromagnet 340 drops instantaneously, providing an impact force on the ground, so that the water seeps into the ground. During the process of the water above the electromagnet 340 falling, it can also squeeze the gas in the inflation space, so that the gas in the inflation space accelerates and is exhausted through the air pump 330. A single complete process of work is completed, and then it works in this way repeatedly until the internal water completely seeps into the bridge deck.

[0106] By increasing the electromagnets 340, the mutually approaching sides of the two electromagnets 340 attract each other, dividing the water in the water storage tank 211 and the aggregation cylinder 310 into upper and lower parts. When squeezing the water below the water storage tank 211 during the inflation process, the sealing performance is improved, increasing the water seepage efficiency when squeezing the water in the cavity below the electromagnet 340. When the mutually approaching sides of the two electromagnets 340 repel each other, under the action of the gravity of the water, it can impact on the water in the lower part, forming a certain impact force. The impact force can act on the water in the cavity below the electromagnet 340 and the ground, accelerating the water seepage efficiency.

[0107] Embodiment 4: When Embodiment 3 is in use, the water in the water storage tank 211 and the aggregation cylinder 310 is separated into upper and lower parts by the attraction of two electromagnets 340. When the two electromagnets 340 repel each other, the impact force generated by the water acts on the ground, accelerating the seepage speed. However, when in use, relying solely on the natural drop of the gravity after the height of the water above the electromagnet 340 is lifted, hitting the water below the electromagnet 340, it is only impacted once, and the efficiency is low. Based on this, the solution of Embodiment 3 is improved as follows Figures 10-13 as shown:

[0108] The impact assembly 300 further includes a baffle 350;

[0109] The baffle 350 is annular, the axis of the baffle 350 is on the same straight line as the axis of the aggregation cylinder 310, the baffle 350 is fixed to the inner wall of the aggregation cylinder 310, and the baffle 350 is located above the electromagnet 340;

[0110] The cross-section of the baffle 350 is rectangular;

[0111] In the initial state, the length direction of the cross-section of the baffle 350 is inclined towards the bottom end of the axis of the water storage tank 211.

[0112] Water is stored in the water storage tank 211. After the water contacts the bridge deck, the air pump 330 inflates the inflation space. During the inflation and expansion process, the water stored inside is squeezed. During the squeezing process, the water can exert pressure on the contacted ground, so that the water seeps into the bridge deck. After expanding to a certain extent, the two electromagnets 340 attract each other, separating the water in the water storage tank 211 and the aggregation cylinder 310 into upper and lower parts. The air pump 330 stops inflating. The mutually approaching sides of the electromagnets 340 repel each other while the air pump 330 extracts the gas in the inflation space. The water above the electromagnet 340 loses support, and the water above the electromagnet 340 instantly drops in height, providing an impact force on the ground. During the height drop process, a part of the internally stored water can be driven downward by the baffle 350, driving the water to act on the ground again, increasing the impact force and enabling the water to seep into the ground. During the process of the water above the electromagnet 340 falling, it can also squeeze the gas in the inflation space, causing the gas in the inflation space to accelerate and be discharged through the air pump 330. A single complete process is completed, and then it works reciprocally until all the internal water completely seeps into the bridge deck; during the inflation and deflation of the inflation space, the baffle 350 can also disturb the flow of the internal water.

[0113] The added baffle 350 can, during the use of the device, increase the force generated when the water on the upper part of the electromagnet 340 impacts the water on the lower part of the electromagnet 340, thereby increasing the generated impact force. At the same time, during the process of inflating and deflating the inflatable space, the baffle 350 can also increase the speed of disturbing the internal water flow and the speed of water sloshing inside, so as to imitate the state of water when a car drives over a puddle at high speed.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
