Description

Technical Field

[0001] The utility model belongs to the technical field of rail transit pouring construction, in particular to an assembled trapezoidal sleeper mould for roadbed pouring. Background Art

[0002] The construction quality of trapezoidal sleeper tracks directly affects the safety and stability of train operation, and also affects the vibration reduction effect of the line.

[0003] The traditional construction method for trapezoidal sleeper tracks involves first pasting and wrapping pearl cotton on the outer side and bottom of the trapezoidal sleepers, then assembling the trapezoidal sleeper rails, hoisting, transporting, and erecting them to the predetermined location. Formwork is then supported and the roadbed concrete is poured. After the concrete strength reaches the required level, the formwork is removed, and the track geometry is fine-tuned. Finally, quality issues are addressed. During the concrete roadbed pouring phase, some defects are difficult to eliminate promptly and effectively due to factors such as the concealed contact area between the trapezoidal sleeper vibration damping pads and the roadbed, damage to the isolation material, and objective factors such as the low technical level of the construction team and the short construction period. Consequently, quality defects such as empty hoisting and "hard contact" often occur, affecting the vibration reduction effect of the trapezoidal sleepers and delaying the construction period.

[0004] Empty suspension means that the vibration damping pad of the trapezoidal sleeper cannot fully contact the concrete roadbed. Figure 1 Partially empty as shown in Figure 2 The entire empty suspension shown in the figure affects the transmission of load on the upper part of the ladder sleeper track;

[0005] "Hard-on-hard" means that the trapezoidal sleeper is in direct contact with the exposed concrete on the roadbed, and the vibration damping pad and the buffer pad cannot fully contact and reduce vibration, affecting the overall vibration reduction effect of the trapezoidal sleeper. Figure 3 and Figure 4 As shown in .

[0006] The main causes of empty suspension are poor concrete flowability, inadequate vibration, and loose wrapping, which can lead to bubbles forming at the contact point between the trapezoidal sleeper vibration damping pad and the trackbed. The main cause of "hard contact" is improper wrapping and bonding of the isolation material, or damage during construction, which causes the concrete to adhere to the main body of the trapezoidal sleeper during trackbed pouring.

[0007] Based on this, the inventors have conducted in-depth research on the roadbed casting work, hoping to design an assembled trapezoidal sleeper mold for roadbed casting that can solve the above-mentioned problems. Utility Model Content

[0008] In order to overcome the above problems, the inventors have conducted intensive research and designed an assembled trapezoidal sleeper mold for roadbed casting. The mold includes a top mold, a bottom mold, a side mold and an end mold, and can be detachably combined. After the combination, a mold longitudinal beam with an outer dimension basically consistent with the trapezoidal sleeper longitudinal beam can be obtained. The two mold longitudinal beams are then consolidated into a trapezoidal sleeper mold with an outer dimension basically consistent with the trapezoidal sleeper through a connecting steel pipe, and then assembled into a mold rail row, which is placed above the roadbed casting position, which is the predetermined placement position of the trapezoidal sleeper. After the roadbed casting is completed, the mold rail row can be removed, thereby conveniently cleaning defects such as empty hanging and adhesion. The mold and method can effectively solve the problems of empty hanging and hard collision, and eliminate the use of isolation materials, reduce the pasting and wrapping process, save costs, and thus complete the present utility model.
