Description

Technical Field

[0001] The invention relates to the technical field of bridge construction, and in particular to a transition structure for preventing vehicles from jumping off a bridge head and a use method thereof. Background Art

[0002] Bridge jumping refers to the phenomenon that vehicles jump and impact when passing due to different degrees of settlement and fracture of the road surface at the backfill of the abutment, thus causing additional impact loads on the bridge culvert and the road surface. Bridge jumping makes drivers and passengers feel bumpy and uncomfortable, and even causes vehicles to slow down significantly. In severe cases, it can lead to traffic accidents, especially vehicle mechanical accidents. Therefore, the bridge jumping problem has become an important factor affecting the engineering quality and cost of high-grade highways.

[0003] The main reasons for bridge jumping include uneven settlement, sudden change in stiffness, and the speed and anti-vibration performance of the vehicle itself. In terms of road conditions, it is mainly caused by uneven settlement at the connection between the flexible road and the rigid structure, resulting in misalignment. There are differences in the composition materials, stiffness, strength, expansion and contraction of the bridge, roadbed and pavement, and concentrated stress is easily formed when the bridge connection is subjected to force. Under the influence of vehicle load, structural deadweight and natural factors, the bridge and road settle at the same time, but the settlement of the two is very different. The settlement of the road is much greater than that of the bridge, resulting in misalignment, which leads to bridge jumping during driving. The hazards of bridge jumping are mainly manifested in: affecting driving safety, reducing driving speed, affecting vehicle operating costs and accelerating the disease of bridges and pavements, which has a great impact on the operation of roads and bridges.

[0004] Effectively solving the problem of vehicle jumping at the bridge head has always been one of the difficult problems that plague management engineering and technical personnel. At present, the general methods used are strengthening soft soil foundation, consolidation method, support method and pavement overlay method, but it is difficult to solve the problem fundamentally, and there are still problems such as long construction period and high cost. For example, the pavement overlay method is to directly pave a new pavement on the original pavement to reduce the pavement slope difference caused by settlement. Due to the increase in load, the settlement after maintenance is further increased, and the same pavement overlay maintenance will inevitably be carried out again at a certain time in the future, resulting in a vicious cycle of post-construction maintenance and post-construction settlement.

[0005] Because the height of the misalignment increases with time, the bridge head is prone to bridge head jumping phenomenon again after treatment, so frequent maintenance and adjustment are required. Therefore, the existing methods for solving bridge head jumping generally have the problems of difficulty in implementation and the need for frequent maintenance. Summary of the invention

[0006] In view of the above problems existing in the prior art, the first technical problem to be solved by the present invention is to provide a transition structure for preventing vehicles from jumping off a bridge head, which has the advantages of simple construction and does not require frequent maintenance.

[0007] The second technical problem to be solved by the present invention is to provide a method for using a transition structure for preventing vehicle jumping at a bridge head.

[0008] In order to solve the above-mentioned first technical problem, the present invention adopts the following technical solution 1:

[0009] A transition structure for preventing a vehicle from jumping off a bridge head comprises a fixing unit and a plurality of adjusting units.

[0010] Fixed unit: The fixed unit includes a dividing groove, a slope and a settlement joint.

[0011] The dividing groove is located between the abutment and the road section, and the dividing groove separates the abutment and the road section.

[0012] The slope is arranged in the dividing groove, the inclined surface of the slope faces the road section, the upper left edge of the slope is at the same height as the abutment, and the lower right edge of the slope is close to the road section.

[0013] The settlement joint is located between the slope and the road section.

[0014] Adjustment unit: Each of the adjustment units includes a column and a plurality of triangular building blocks.

[0015] The column is composed of a plurality of column blocks with the same structure. A docking groove is provided on the upper surface of each column block, and a docking block is provided on the lower surface of each column block. The docking block and the column block are an integral structure. The plurality of column blocks are distributed in the vertical direction, and two adjacent columns are matched through the docking groove and the gap between the docking blocks.

[0016] The triangular building blocks are divided into two types: straight triangular building blocks and oblique triangular building blocks. The two straight triangular building blocks and the two oblique triangular building blocks can be spliced ​​into a rectangular parallelepiped. Each of the triangular building blocks is provided with a through hole. When the two straight triangular building blocks and the two oblique triangular building blocks are spliced ​​into a rectangular parallelepiped, the through holes on each triangular building block are coaxial.

[0017] The columns pass through the through holes on a plurality of triangular building blocks, and the columns are gap-matched with the through holes, and each triangular building block can slide along the columns.

[0018] The plurality of adjustment units are evenly arranged in the dividing groove from left to right, the lower end of the column in each adjustment unit vertically penetrates the slope, and the distance between two adjacent columns is equal to the length of the rectangular parallelepiped.

[0019] The top surfaces of the multiple adjustment units are in the same plane, and the plane and the abutment are in the same horizontal plane.

[0020] A smooth transition between the abutment and the road section is achieved by setting a fixed unit and multiple adjustment units, wherein a dividing groove separates the abutment from the road section, a slope is set in the dividing groove to provide a reserve for the settlement of the road section, and a settlement joint can separate the settlement of the road section from the soil below the slope, effectively preventing the slope from sinking with the road section. Multiple adjustment units are set in the dividing groove, and the columns stabilize the triangular blocks to prevent the triangular blocks from sliding down the inclined surface so that the triangular blocks are forced downward. The triangular blocks are used to fill the height difference between the slope and the road section, thereby achieving a smooth transition between the abutment and the road section.

[0021] When the road section sinks, there is a height difference between the abutment and the road section. At this time, you only need to remove some of the column blocks and some of the triangular blocks on the columns in each adjustment unit to form a relatively gentle slope between the abutment and the road section. Vehicles can drive smoothly from the abutment to the road section, which can effectively avoid the phenomenon of jumping off the bridge head. Each time the settlement value increases, you only need to adjust the column height and the number of triangular blocks on the corresponding column accordingly, so that the abutment and the road section can be smoothly transitioned again. The adjustment is simple and does not require complex maintenance, which greatly saves maintenance costs.

[0022] Preferably, a first annular groove is provided on the upper surface of each triangular building block near the left and right sides.

[0023] A first rotating block and a first hanging ring are arranged in each first annular groove, and the first hanging ring is an open annular ring.

[0024] The first rotating block is fixedly connected to the bottom of the first annular groove, and both ends of the opening of the first hanging ring are rotatably connected to the first rotating block respectively.

[0025] By setting the first lifting ring, the triangular building blocks can be easily transported. When the triangular building blocks need to be added to or removed from the column, they can be connected to the lifting equipment through the first lifting ring. The triangular building blocks can be safely and quickly transported without complicated bundling, which reduces the construction difficulty and improves the construction speed.

[0026] Preferably, a second annular groove is provided on the upper surface of each column block near the front and rear sides.

[0027] A second rotating block and a second lifting ring are provided in each second annular groove, and the second lifting ring is an open annular ring.

[0028] The second rotating block is fixedly connected to the bottom of the second annular groove, and both ends of the opening of the second hanging ring are rotatably connected to the second rotating block respectively.

[0029] By setting up the second lifting ring, it is convenient to carry the column block. When it is necessary to add or remove the column block from the column, it can be connected to the lifting equipment through the second lifting ring. The column block can be safely and quickly carried without complicated bundling of the column block, which reduces the construction difficulty and improves the construction speed.

[0030] Preferably, the slope is cast by concrete, and the slope and the abutment are consolidated into a whole.

[0031] The slope is made of cast concrete, which makes the slope have better structural strength and load capacity. At the same time, the slope and the abutment are consolidated to form a whole, so that there will be no height difference between the slope and the abutment, thereby effectively avoiding new bridge head jumping phenomenon caused by the height difference between the slope and the abutment.

[0032] Preferably, a plurality of drainage grooves are provided on the inclined surface of the slope, and the drainage grooves are connected to the road drainage network.

[0033] By setting up drainage grooves, rainwater flows along the gaps between the triangular blocks to the slope and is discharged through the drainage grooves on the slope, thus effectively preventing the water on the slope from flowing into the settlement joints or the soil below the slope, accelerating the settlement of the road section.

[0034] Preferably, each of the drainage grooves is provided with a steel grating plate, which is prior art.

[0035] By installing steel gratings, larger dirt that arrives on the slope with rainwater can be blocked, preventing the dirt from entering the gutter and clogging it, greatly improving the working stability of the gutter.

[0036] Preferably, the column blocks and triangular building blocks are made of lightweight and high-strength metal materials.

[0037] By using lightweight and high-strength metal materials, the column blocks and triangular blocks have higher strength, which can prevent the columns and triangular blocks from being deformed or damaged under the impact of long-term vehicle driving. At the same time, it can avoid causing a large load on the slope and the soil below the slope, causing the soil to sink, thereby greatly improving the stability and reliability of the transition structure.

[0038] Preferably, the outer surfaces of the column blocks and triangular building blocks are sprayed with anti-rust paint.

[0039] By spraying anti-rust paint on the outer surfaces of the column blocks and the triangular blocks, the column blocks and the triangular blocks can be effectively prevented from being rusted and damaged due to erosion by rain and water vapor, thereby improving the stability and reliability of the transition structure.

[0040] In order to solve the above second technical problem, the present invention adopts the following technical solution 2:

[0041] A method for using a transition structure for preventing a vehicle from jumping off a bridge head, using the transition structure for preventing a vehicle from jumping off a bridge head described in technical solution one.

[0042] S1: Measure the height difference between the bridge abutment and the road section due to the settlement of the road section.

[0043] S2: according to the height difference between the abutment and the road section, remove part of the column blocks and part of the triangular blocks on the column (3) in each adjustment unit so that the top surfaces of the plurality of adjustment units form a relatively gentle slope between the abutment and the road section, thereby achieving a smooth transition between the abutment and the road section.

[0044] Compared with the prior art, the present invention has at least the following advantages:

[0045] 1. In the present invention, a fixed unit and a plurality of adjustment units are provided to achieve a smooth transition between the abutment and the road section, wherein a dividing groove separates the abutment from the road section, a slope is provided in the dividing groove to provide a reserve for the settlement of the road section, and a settlement joint is provided to separate the settlement of the road section from the soil below the slope, thereby effectively preventing the slope from sinking with the road section. A plurality of adjustment units are provided in the dividing groove, and columns stabilize the triangular blocks to prevent the triangular blocks from sliding down the inclined surface so that the triangular blocks are subjected to force downward, and the triangular blocks are used to fill the height difference between the slope and the road section, thereby achieving a smooth transition between the abutment and the road section.

[0046] 2. In the present invention, by setting the first lifting ring and the second lifting ring, the triangular building blocks and the column blocks can be transported. When it is necessary to add or remove the column blocks or triangular building blocks on the column, they can be connected to the lifting equipment through the first lifting ring or the second lifting ring. There is no need to carry out complicated bundling of the column blocks or triangular building blocks, so the column blocks or triangular building blocks can be safely and quickly transported, which reduces the construction difficulty and improves the construction speed.

[0047] 3. In the present invention, the slope is cast by concrete, so that the structural strength of the slope is better and the load capacity is good. At the same time, the slope and the abutment are consolidated to form a whole, so that there will be no height difference between the slope and the abutment, thereby effectively avoiding new bridge head jumping phenomenon caused by the height difference between the slope and the abutment.

[0048] 4. In the present invention, by setting up drainage grooves, rainwater flows along the gaps between the triangular blocks to the slope and is drained away through the drainage grooves on the slope, thereby effectively preventing the water on the slope from flowing into the settlement joints or the soil below the slope, accelerating the settlement of the road section. By setting up steel grating plates, large dirt that arrives on the slope with rainwater can be blocked, preventing dirt from entering the drainage grooves and clogging the drainage grooves, greatly improving the working stability of the drainage grooves.

[0049] 5. In the present invention, when the road section sinks, there is a height difference between the abutment and the road section. At this time, it is only necessary to remove part of the column blocks and part of the triangular blocks on the columns in each adjustment unit to form a relatively gentle slope between the abutment and the road section. Vehicles can drive relatively smoothly from the abutment to the road section, thereby effectively avoiding the phenomenon of vehicle jumping at the bridge head. Each time the settlement value increases, it is only necessary to adjust the column height and the number of triangular blocks on the corresponding column accordingly, so that the abutment and the road section can be smoothly transitioned again. The adjustment is simple, and no complicated maintenance is required, which greatly saves maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0065] Adjustment unit: Each of the adjustment units includes a column 3 and a plurality of triangular building blocks 2.

[0066] The column 3 is composed of a plurality of column blocks 31 of the same structure. A docking groove 32 is provided on the upper surface of each column block 31, and a docking block 33 is provided on the lower surface of each column block 31. The docking block 33 is an integral structure with the column block 31. The plurality of column blocks 31 are distributed in the vertical direction, and two adjacent columns 3 are fitted through the gap between the docking groove 32 and the docking block 33.

[0067] The triangular building blocks 2 are divided into two types: a straight triangular building block 21 and an oblique triangular building block 23. The two straight triangular building blocks 21 and the two oblique triangular building blocks 23 can be spliced ​​into a rectangular parallelepiped. Each of the triangular building blocks 2 is provided with a through hole 22. When the two straight triangular building blocks 21 and the two oblique triangular building blocks 23 are spliced ​​into a rectangular parallelepiped, the through holes 22 on each triangular building block 2 are coaxial.

[0068] The columns 3 pass through the through holes 22 on the plurality of triangular building blocks 2 , and the columns 3 are clearance-matched with the through holes 22 , so that each triangular building block 2 can slide along the columns 3 .

[0071] During specific implementation, the slope length, slope, column size, triangular block size, etc. can be adjusted according to the width of the road section and the predicted value of the road section's subsidence. At the same time, when the road is wider, multiple columns can be evenly arranged vertically in a road cross-section, and the distance between two adjacent columns is consistent with the width of the above-mentioned rectangular block, that is, when looking down at the dividing groove, the columns in the dividing groove are distributed in a matrix.

[0072] Furthermore, a first annular groove 61 is provided on the upper surface of each triangular building block 2 near the left and right sides.

[0073] A first rotating block 62 and a first hanging ring 63 are disposed in each first annular groove 61 . The first hanging ring 63 is an open annular ring.

[0074] The first rotating block 62 is fixedly connected to the bottom of the first annular groove 61, and both ends of the opening of the first hanging ring 63 are respectively rotatably connected to the first rotating block 62. In specific implementation, the first hanging ring 63 can rotate around the first rotating block 62 to be vertical.

[0075] Furthermore, a second annular groove 71 is provided on the upper surface of each column block 31 near the front and rear sides.

[0076] A second rotating block 72 and a second hanging ring 73 are disposed in each second annular groove 71 , and the second hanging ring 73 is an open annular ring.

[0077] The second rotating block 72 is fixedly connected to the bottom of the second annular groove 71 , and both ends of the opening of the second hanging ring 73 are rotatably connected to the second rotating block 72 .

[0081] Furthermore, the column block 31 and the triangular building block 2 are both made of light and high-strength metal materials, such as titanium alloy, aluminum alloy, and aluminum-magnesium alloy.

[0082] Furthermore, the outer surfaces of the column block 31 and the triangular building block 2 are sprayed with anti-rust paint. In specific implementation, iron red alcohol paint, iron red phenolic paint, zinc yellow paint and gray paint can be used.

[0083] See also Figure 1-6 Embodiment 2: A method for using a transition structure for preventing a vehicle from jumping off a bridge head, using the transition structure for preventing a vehicle from jumping off a bridge head described in Embodiment 1.

[0084] S1: Measure the height difference between the abutment 4 and the road section 5 caused by the settlement of the road section 5.

[0085] S2: According to the height difference between the abutment 4 and the road section 5, part of the column blocks 31 that form the columns 3 in each adjustment unit and part of the triangular blocks 2 on the columns 3 are removed, so that the top surfaces of the multiple adjustment units form a relatively gentle slope between the abutment 4 and the road section 5, thereby achieving a smooth transition between the abutment 4 and the road section 5.

[0086] The working principle of a transition structure for preventing vehicle jumping at a bridge head defined by the present invention is as follows:

[0087] The dividing groove separates the abutment 4 from the road section 5. The left end of the slope 1 is flush with the abutment 4, and the left end of the slope 1 is consolidated into a whole with the abutment 4. At the same time, the settlement joint 11 separates the soil of the slope 1 from the road section 5, so that the slope 1 will not settle with the road section 5. The slope 1 provides a reserved amount for the settlement of the road section 5.

[0088] A plurality of adjustment units are located in the dividing groove, and the lower end of the column 3 in each adjustment unit is located in the slope. The column 3 is fixed on the slope 1, and a plurality of triangular blocks 2 are arranged on each column 3. The through holes on the triangular blocks 2 pass through the column 3. Under the action of the column 3, the triangular blocks 2 will not slide along the slope 1, so that the triangular blocks 2 are stably arranged on the slope 1. Every two adjacent triangular blocks 2 on each column 3 are respectively a straight triangular block 21 and an oblique triangular block 23. The triangular blocks 2 in each adjustment unit are stacked upward to fill the space above the slope 1, and the top surfaces of the plurality of adjustment units are in the same plane, and the plane is in the same horizontal plane as the abutment 4, so that the abutment 4 and the road section 5 have a smooth transition, so that the vehicle will not jump off the bridge head when passing by.

[0089] The working process of the method for using a transition structure for preventing vehicle jumping at a bridge head defined by the present invention is as follows:

[0090] When the road section 5 sinks, there is a height difference between the abutment 4 and the road section 5. Since the triangular building blocks 2 can slide vertically along the columns 3, and every two adjacent column blocks 31 in each column are connected by the docking grooves 32 and the docking blocks 33, it is only necessary to remove part of the column blocks 31 and part of the triangular building blocks 2 on each column 3 at this time, so that the top surface of each adjustment unit forms a relatively gentle slope between the abutment 4 and the road section 5, thereby effectively avoiding the phenomenon of vehicle jumping at the bridge head due to road settlement.

[0091] The transition structure and use method for preventing vehicles from jumping off a bridge head are simple and easy to understand, with low construction difficulty. Each time the settlement value changes, it is only necessary to adjust the number of column blocks 31 and triangular building blocks 2 on each column 3 to make a smooth transition between the abutment and the road section. No complicated maintenance is required, thereby avoiding maintenance costs caused by continuous settlement of the road.

[0092] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
