Description

Technical Field

[0001] The present invention relates to the technical field of track construction, and particularly to an integrated construction method for a ladder sleeper track. Background Art

[0002] In order to reduce the impact of urban rail transit vibration and noise on the surrounding environment, appropriate vibration and noise reduction measures need to be taken in the required sections. Among them, the ladder sleeper track is one of the common high-grade vibration and noise reduction measures and is widely applied in the domestic urban rail transit network.

[0003] The construction technology of the ladder sleeper track has a great impact on its vibration and noise reduction performance. At present, the traditional construction method of the ladder sleeper track is to directly erect the assembled ladder sleeper rail row on the steel bar mesh after the bedding steel bars are tied, and formwork and pour the bedding concrete on the side. This method requires manual plastering of the cast-in-place bedding, has high requirements for construction fineness, a long construction period, and is prone to problems such as incomplete wrapping of the isolation material resulting in adhesion between the ladder sleeper and the bedding, or air suspension and clearance due to insufficient vibration and compaction of the bedding concrete under the vibration damping pad of the ladder sleeper, directly leading to the failure of the vibration damping function of the ladder sleeper. Summary of the Invention

[0027] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will further describe the embodiments of the present invention in detail in conjunction with the accompanying drawings.

[0028] As Figure 1 shown, an integrated construction method for a trapezoidal sleeper track according to an embodiment of the present invention includes the following steps:

[0029] S1. Assemble the rail, fasteners, and trapezoidal sleepers into a to - be - processed track panel according to the track panel length requirements, and bind the bed reinforcement mesh;

[0030] S2. Place the to - be - processed track panel above the elastic vibration - damping components of the trapezoidal sleeper, place the precast base sleeper below the trapezoidal sleeper, and fix the trapezoidal sleeper and the precast base sleeper through angle steel or bolts to form an assembled structure;

[0031] S3. Through the reserved steel bars in the assembled structure, perform binding connection processing with the bed reinforcement mesh to obtain a to - be - processed device;

[0032] S4. After transporting the to - be - processed device to the laying position on the construction operation surface, perform bed pouring treatment, and after a preset time, perform bed formwork removal treatment to complete the construction.

[0033] The beneficial effects of an integrated construction method for a trapezoidal sleeper track provided by the present invention are as follows:

[0034] Introduce a precast base sleeper structure between the bed and the trapezoidal sleeper. The precast base sleeper and the bed are bound through reserved steel bars, and the trapezoidal sleeper is directly placed on the precast base sleeper without participating in the bed pouring process, which can improve the construction efficiency and ensure the effective exertion of the vibration - damping effect of the trapezoidal sleeper.

[0035] Rails refer to: Rails are the main components of railway tracks, used to guide the wheels of locomotives and vehicles, bear the huge pressure of the wheels, and transmit it to the sleepers. Rails must provide a continuous, smooth and minimally resistant rolling surface for the wheels. In addition, in electrified railways or automatic block sections, rails can also serve as track circuits.

[0036] The cross-section of the rail is shaped like the Chinese character “工” and consists of three parts: the rail head, the rail waist and the rail bottom. In order for the rail to better withstand forces from all sides and ensure the necessary strength conditions, the rail should be high enough, its head and bottom should have sufficient area and height, and the waist and bottom should not be too thin.

[0037] Rails are classified by use and weight, with common specifications being 75kg / m, 60kg / m, 50kg / m, etc. In addition, there are also detailed regulations for the production standards of rails. For example, the standard for crane rails is YB / T5055-2014, which specifies the size, shape, weight, and allowable deviation.

[0038] The fastener can also be a rail fastener, which is a part that connects the rail and the sleeper, also known as an intermediate connecting part. Its main function is to fix the rail on the sleeper, maintain the track gauge and prevent the rail from moving longitudinally and transversely relative to the sleeper.

[0039] Trapezoidal sleepers refer to: the use of prefabricated prestressed concrete longitudinal beam structure, combined with vibration-damping pads and buffer pads, to form a system structure that actively isolates vibrations and reduces noise.

[0040] The trapezoidal sleeper is mainly composed of two prefabricated prestressed concrete longitudinal beams and their limiting bosses, steel cross beams, polyurethane vibration damping pads and buffer pads. This structure enables the trapezoidal sleeper to effectively disperse the dynamic stress of the wheel and rail when the high-speed train is running, reduce the peak compressive stress of the base, and absorb vibration energy through the vibration damping pad, thereby reducing the vibration and noise impact on the surrounding environment and buildings.

[0041] The rail length requirement is the length value that needs to be processed based on actual conditions.

[0042] Track bed steel mesh refers to a structural component used to reinforce and support the ballastless track bed, which is mainly composed of high-strength steel bars as the skeleton and tightly wrapped with steel mesh. It is widely used in fields such as high-speed railways and urban rail transit to improve the bearing capacity and wind, earthquake and wave resistance of the ballastless track bed, thereby ensuring the stability and safety of train travel.

[0043] The ballast steel reinforcement mesh uses high-strength steel bars as the framework and undergoes anti-corrosion treatments such as galvanizing and plastic spraying to improve its corrosion resistance and service life. In addition, the steel reinforcement mesh sheets are light in weight and convenient for loading and unloading, and can be quickly laid on the ballastless track bed, thus improving the construction efficiency and quality.

[0044] The elastic vibration damping component of the ladder-shaped sleeper is the vibration damping pad of the ladder-shaped sleeper.

[0045] Above the elastic vibration damping component refers to the direction away from the ground when the elastic vibration damping component is placed on the ground according to the usage method.

[0046] Below the ladder-shaped sleeper is the direction 180 degrees opposite to the above direction of the elastic vibration damping component.

[0047] The precast base sleeper, also known as the sleeper, is an important part of the railway track. Its main functions include supporting the rail, keeping the rail position stable, and transmitting the huge pressure brought by the train to the ballast bed to prevent the rail from sinking due to excessive pressure.

[0048] Sleepers are made of various materials, including wood, steel, and concrete. Wood was widely used because of its good elasticity, insulation, light weight, and easy replacement. However, due to environmental protection and durability considerations, wood has gradually been replaced by other materials. Although steel has high strength, it is heavy and costly. Concrete sleepers have become the main choice for modern railways due to their long service life, good track stability, and small maintenance workload.

[0049] Furthermore, before assembling into the track panel to be processed, it also includes: cleaning the rail, the fastener, and the ladder-shaped sleeper.

[0050] Furthermore, before the ballast bed pouring treatment, it also includes: initially adjusting the placement position of the device to be processed.

[0051] Furthermore, after initially adjusting the device to be processed, it also includes: finely adjusting the placement position of the device to be processed.

[0052] Furthermore, the specific process of the ballast bed pouring treatment is as follows:

[0053] Install the ballast bed formwork and carry out the ballast bed pouring treatment in a one-way pouring manner.

[0054] Furthermore, the specific process of the ballast bed formwork removal treatment is: real-time detecting the target strength of the device after the ballast bed pouring treatment, and when the target strength meets the preset conditions, carrying out the ballast bed formwork removal treatment on the device after the ballast bed pouring treatment.

[0055] Furthermore, it also includes: during the process of real-time detecting the target strength of the device after the ballast bed pouring treatment, carrying out the watering and curing treatment on the device after the ballast bed pouring treatment.

[0056] Example 1, as Figure 2 shown, Step 1, Subgrade Treatment and Benchmark Setting before Construction: After the civil engineering handover is completed, clean the floating slurry, dirt, and dirty water on the subgrade surface of the track structure to maintain a good connection between the ballast bed and the subgrade. According to the CPⅢ control points, set the encrypted benchmarks.

[0057] Step 2, Assembly of the Ladder Sleeper Track Panel: Assemble the rail, fasteners, and ladder sleepers into a track panel according to the requirements of the track panel length. Compared with the traditional assembly process of the ladder sleeper track panel, since the ladder sleeper track panel and the cast-in-place concrete ballast bed in the present invention are non-contact installations, the construction processes of pasting isolation materials and wrapping and sealing the ladder sleepers in the traditional process can be omitted.

[0058] Step 3, Assembly of the Track Panel and the Prefabricated Base Sleeper: Lift the assembled track panel, place the prefabricated base sleeper under the ladder sleeper at the position of the elastic vibration damping material of the ladder sleeper, and connect the ladder sleeper and the prefabricated base sleeper through angle steel or bolts.

[0059] Step 4, Binding Connection between the Ballast Bed Reinforcement Mesh and the Prefabricated Base Sleeper: After the processing of the ballast bed reinforcement mesh is completed, place the assembled structure of the ladder sleeper track panel and the prefabricated base sleeper on the ballast bed reinforcement mesh, and bind and connect the assembled structure to the ballast bed reinforcement mesh through the steel bars reserved under the prefabricated base sleeper.

[0060] Step 5, Transportation and Erection of the Assembled Structure: Transport the assembled structure of the ladder sleeper track panel, the prefabricated base sleeper, and the ballast bed reinforcement mesh to the construction operation surface, and position and place it at the laying position through the track laying benchmarks. After the initial adjustment of the position of the assembled structure is completed, before pouring the ballast bed concrete, finely adjust the position, elevation, direction, etc. of the rail according to the benchmarks.

[0061] Step 6, Ballast Bed Pouring: The height of the ballast bed formwork should reach 1 / 2 of the height of the prefabricated base sleeper and be firmly installed; the ballast bed concrete is poured unidirectionally, that is, starting from the two outer sides of the ladder sleeper, and strengthen the vibration of the concrete at the bottom of the prefabricated base sleeper. Since the prefabricated base sleeper increases the space between the cast-in-place concrete ballast bed and the ladder sleeper, the vibration work of the ballast bed will be easier, avoiding the adhesion between the ladder sleeper and the cast-in-place concrete ballast bed, or the problem of empty suspension due to insufficient vibration. At the same time, the introduction of the prefabricated sleeper can reduce the consumption of ballast bed concrete and optimize the pouring time.

[0062] Step 7, Ballast Bed Maintenance and Formwork Removal: Cover and sprinkle water for the maintenance of the cast-in-place concrete ballast bed, and remove the formwork after reaching the strength requirements. After the formwork is removed, immediately clean the excess concrete.

[0063] Advantages of the present invention:

[0064] 1. The present invention introduces a precast base sleeper structure between the concrete roadbed and the ladder sleeper, which can completely isolate the roadbed from the ladder sleeper, effectively increase the space under the bottom of the ladder sleeper, and avoid the adhesion between the ladder sleeper and the roadbed; the damping pads of the ladder sleeper are closely attached to the precast base sleeper throughout the construction process, avoiding the problems of empty suspension and separation joints, and can effectively ensure the exertion of the damping effect of the ladder sleeper.

[0065] 2. The introduction of the precast base sleeper in the present invention completely avoids the direct contact between the ladder sleeper and the roadbed, increases the space between the ladder sleeper and the roadbed surface, and there is no need to perform the traditional construction processes of pasting isolation materials and wrapping and sealing on the ladder sleeper, greatly improving the track panel assembly efficiency.

[0066] 3. The present invention introduces a precast base sleeper in the construction process of the ladder sleeper, which can provide favorable conditions for reducing the designed height of the roadbed, thereby reducing the amount of cast-in-place concrete for the roadbed.

[0067] 4. The precast base sleeper in the present invention is directly tied and cast with the roadbed. The work such as vibration and plastering during the concrete pouring process of the roadbed can obtain a more favorable working space, reducing the working time at the pouring working surface, which is beneficial to the rapid construction of the ladder sleeper track.
