Description

Technical Field

[0001] The present application relates to the technical field of ballastless track systems, and in particular to a construction method for a CRTS III type base plate force transmission gasket. Background Art

[0002] With the development of high-speed railways, the CRTSⅢ slab ballastless track system is a new system for construction on passenger dedicated lines. The ballastless track construction technology is widely adopted on more and more passenger dedicated lines due to its advantages such as high stability, good uniformity of rigidity and strong structural durability.

[0003] In this system, a force-transfer gasket is installed between two adjacent base plates. The force-transfer gasket is a key component, and its core functions include: transferring longitudinal loads to coordinate the forces on the track structure during train operation (starting, braking, acceleration and deceleration) and temperature changes; allowing adjacent base plate sections to produce slight relative expansion and contraction deformations to avoid cracking caused by temperature stress; ensuring the integrity and stability of the track structure; and limiting lateral displacement to maintain line direction stability.

[0004] However, referring to Figure 6 and Figure 7 As shown, the construction of force-transfer gaskets in the prior art has significant defects: in order to facilitate the alignment of the base plate templates on both sides, the length of the transfer gasket is usually slightly shorter than the width of the base plate, and it mainly relies on the top suspension for positioning. This setting results in the two ends of the force-transfer gasket being unable to completely cover the base plate joint area, resulting in the loss of force transmission function in this area, and then the concrete at the edge of the base plate without protection is very easy to crack under the action of stress; at the same time, this construction method cannot guarantee the flatness of the force-transfer gasket, and wrinkles are very likely to appear, resulting in a reduction in the effective contact area; stress concentration will form at the wrinkles, which will not only significantly reduce the ability and efficiency of the force-transfer gasket to transmit shear force, but also accelerate the fatigue cracking, hardening and permanent deformation of the force-transfer gasket, and accelerate the aging, deterioration and failure of the gasket as a whole; in addition, wrinkles destroy the flatness and closeness of the contact surface between the force-transfer gasket and the concrete, forming a water seepage channel, resulting in the weakening or even loss of the waterproof sealing function.

[0011] According to the technical solution provided by this application, step S500 further includes the following steps: S600: Remove the base plate template and cut off the portion of the force transmission gasket exposed from the base plate.

[0021] In order to make the technical solution of the present application clearer and easier to understand, the construction method of a CRTSⅢ type base plate force transmission gasket provided in an embodiment of the present application is introduced below.

[0022] like Figure 1 As shown, this embodiment provides a construction method for a CRTS III type base plate force transmission gasket, the method comprising the following steps: S100: Determine the laying positions of two adjacent sections of base plate 9, and erect a pair of base plate templates 7 corresponding to each laying position. A forming space is formed between the pair of base plate templates 7, and a first gap is formed at the joint of two adjacent base plate templates 7 on the same side. Specifically, based on the design plan and route of the CRTS III type base plate, the laying positions of two adjacent base plates 9 are accurately determined, and the laying area is carefully cleaned and the base layer is treated to ensure a flat and solid construction surface. Subsequently, at each determined laying position, a pair of base plate templates 7 are erected according to the designed size and shape of the base plate 9 to form a molding space that meets the requirements for casting the base plate 9. In this embodiment, the two base plate templates 7 do not contact each other, and space for the force transmission gasket 6 is left between them. Specifically, in this embodiment, the cross-sectional size of the base plate template 7 is 300 mm*100 mm.

[0023] S200: Install the force transmission gasket 6 between two adjacent pairs of base plate templates 7 through a fixing component, and the fixing component is used to make the force transmission gasket 6 perpendicular to the direction of the base plate 9 and keep it flat; the two ends of the force transmission gasket 6 respectively extend into the first gap corresponding thereto.

[0024] Specifically, such as Figure 2 As shown, the fixing assembly includes: a fixing plate 2 and a pressing plate, a clamping plate 1 is provided on the top of the fixing plate 2; the pressing plate is arranged parallel to one side of the fixing plate 2, and the pressing plate and the fixing plate 2 are detachably connected through a connecting piece; a force transmission gasket 6 is arranged between the fixing plate 2 and the pressing plate; in this embodiment, the fixing plate 2 and the pressing plate are both steel plates; Specifically, a force transmission gasket 6 with a length greater than the width of the base plate 9 to be cast is selected to ensure that the joint between the two adjacent base plates 9 is completely covered; in this embodiment, the size of the force transmission gasket 6 is 20mm (thickness) × 220mm (width) × 3100mm (length); then, the force transmission gasket 6 is accurately installed between the two adjacent sections of the base plate formwork 7 through a fixing assembly, and the fixing assembly includes components such as a fixing plate 2, a clamping plate and a connecting member 5. The clamping plate is tightened by the connecting member 5 to uniformly press the force transmission gasket 6 onto the fixing plate 2; the fixing assembly can ensure that the force transmission gasket 6 always maintains a vertical relationship with the base plate 9 during the installation process, and at the same time, the surface of the force transmission gasket 6 meets strict flatness requirements through the uniformly applied clamping force. Among them, the extra-long design of the force transmission gasket 6 enables its two ends to fully extend into the corresponding first gap to form a complete force transmission path. This key feature effectively avoids the stress concentration and cracking of the end concrete caused by the insufficient length of the force transmission gasket 6 in traditional construction; in this embodiment, the size of the fixed plate 2 is 2mm (thickness) × 320mm (width) × 3100mm (length), and the cross-sectional size of the clamping plate 1 is 40mm×40mm, and the length is 3200mm.

[0025] Optional, hold-down plate includes: The pressing portion 3 is arranged on a side of the force transmission gasket 6 away from the fixing plate 2, and the pressing portion 3 extends along a first direction; the first direction is parallel to the length direction of the force transmission gasket 6; The connecting portion 4 has multiple connecting portions 4, and the multiple connecting portions 4 are arranged along the first direction; and each connecting portion 4 extends along the second direction, and the connecting portion 4 is used to connect with the connecting member 5; the second direction is perpendicular to the first direction.

[0026] Specifically, in this embodiment, the first direction is the horizontal direction, and the second direction is the vertical direction; Specifically, the clamping plate is mainly composed of a clamping part 3 and a connecting part 4. The clamping part 3 is a long steel plate component. In this embodiment, the dimensions of the clamping part 3 are 20 mm (thickness) × 40 mm (width) × 3100 mm (length); the clamping part 3 is extended along the length direction (first direction) of the force transmission gasket 6, and is tightly fitted to the side surface of the force transmission gasket 6 facing away from the fixed plate 2, ensuring that a uniform clamping force is applied to the gasket as a whole; the connecting part 4 is an ear plate structure welded to the clamping part 3, and at least three are provided and arranged at equal intervals along the first direction. Each connecting part 4 extends along the second direction to form a standard connection interface. In this embodiment, the dimensions of the connecting part 4 are 20 mm (thickness) × 150 mm (length) × 40 mm (width). Each connection part 4 is connected to the corresponding connection piece 5 to achieve connection with the fixed plate 2; this orthogonal arrangement of the clamping part 3 and the connecting part 4 structure not only ensures the continuous distribution of the clamping force along the length direction of the force transmission gasket 6, but also realizes the rigid fixation of the clamping system through multi-point connection, effectively avoiding the local stress concentration and uneven clamping phenomena commonly seen in traditional construction; wherein, the length of the clamping part 3 matches the working section length of the force transmission gasket 6 to ensure that the entire effective force transmission area is covered; the number and spacing of the connecting parts 4 are determined based on the fluid pressure calculation during concrete pouring to ensure that a stable clamping effect can be maintained under the maximum construction load.

[0027] Optionally, each connecting portion 4 is connected to a corresponding connecting member 5, and the connecting member 5 includes: a screw 54 rotatably connected to the connecting portion 4 , the screw 54 extending along a third direction perpendicular to the first direction and perpendicular to the second direction; The connecting nut includes a nut body 52, which is threadedly connected to the screw 54; an extension portion 51 is provided on one side of the nut body 52, and the extension portion 51 extends toward the side of the connecting portion 4 along the third direction; one end of the extension portion 51 away from the nut body 52 is bent toward the side of the connecting portion 4 to form a clamping portion 53; the clamping portion 53 is used to clamp with the fixing plate 2.

[0028] Specifically, in this embodiment, the third direction is the horizontal direction; Specifically, such as Figure 8As shown, the connecting member 5 consists of a screw 54 and a connecting nut; the screw 54 is made of high-strength alloy steel, and its axis is arranged along a third direction perpendicular to the length direction of the pressing part 3 and the extension direction of the connecting part 4; the connecting nut adopts a three-way split design, including a nut body 52, the nut body 52 is provided with an internal thread matching the screw 54, and axial locking is achieved by screwing; an extension portion 51 is fixed to one side of the nut body 52, and the extension portion 51 extends toward the side of the connecting part 4 along the third direction; the end of the extension portion 51 away from the nut body 52 is bent toward the side of the connecting part 4 to form a clamping portion 53; the clamping portion 53 is used to clamp with the fixing plate 2 ; This unique connecting piece 5 structure realizes the balance of forces in three-dimensional directions: the extension part 51 bears the axial preload, the screw body 52 provides the main tightening force through the threaded connection, and the clamping part 53 forms an auxiliary clamping fixation. The three work together to ensure that the clamping system does not shift or loosen during the concrete pouring process; in particular, the extension part 51, the nut body 52 and the clamping part 53 of the connecting nut are formed by an integrated forging process; at the same time, this design of the connecting piece 5 enables construction personnel to simply rotate the screw 54 to simultaneously complete the dual functions of axial tightening and radial positioning, which greatly improves construction efficiency and quality stability.

[0029] Optionally, step S200 includes the following steps: S201: Lay the force transmission gasket 6 flatly on one side of the fixed plate 2; S202: placing a pressing plate on the side of the force transmission gasket 6 away from the fixing plate 2, and fixing the pressing plate to the fixing plate 2 via the connecting member 5; S203: Install the assembled force transmission gasket 6 and the fixing assembly between two adjacent pairs of base plate templates 7, and make the clamping plate 1 and the base plate template 7 form a limited fixation.

[0030] Specifically, such as Figure 2 and Figure 3 As shown, first, the force transmission gasket 6 is laid flat on the installation surface of the fixed plate 2 to ensure that the surface of the force transmission gasket 6 is completely flat and wrinkle-free; then a clamping plate is placed above the force transmission gasket 6, and the clamping plate and the fixed plate 2 are squeezed and tightened by the connecting piece 5 to make the force transmission gasket 6 evenly compacted; finally, the assembled force transmission gasket 6 and the fixing component are installed as a whole between the two adjacent sections of the base plate formwork 7, and precise positioning and firm fixation are achieved through the cooperation of the clamping plate 1 and the formwork; in this embodiment, the clamping plate 1 is clamped to the top of the base plate formwork 7; this process effectively ensures the flatness and position accuracy of the force transmission gasket 6 during the construction process, creating good conditions for subsequent concrete pouring.

[0031] Optionally, after step S200 and before step S300, the following steps are further included: S210: A blocking member 8 is installed in the first gap, and the blocking member 8 is used to abut against the end of the force transmission gasket 6 to limit the position.

[0032] Specifically, a first gap is formed at the joint of two adjacent sections of the base plate formwork 7, and the gap size matches the thickness of the force transmission gasket 6; in this embodiment, the first gap is 20 mm; a sealing member 8 is provided in the first gap at both ends, and the sealing member 8 is preferably made of 20 mm thick steel plate, and its installation position corresponds to the end position of the force transmission gasket 6; through this arrangement, the sealing member 8 can form a tight mechanical abutment with the end of the force transmission gasket 6, thereby realizing a two-way limit constraint on the force transmission gasket 6; on the one hand, this structural design ensures that the force transmission gasket 6 maintains a stable planar position during the concrete pouring process to prevent it from being offset or twisted; on the other hand, it provides tensile strength for both ends of the force transmission gasket 6, thereby achieving the flatness of the force transmission gasket 6 on its entire plane, completely eliminating possible wrinkle defects.

[0033] S300: Concrete is poured synchronously in the base plate formwork 7 on both sides of the force transmission gasket 6; S400: After the concrete pouring is completed, the fixing components are removed; S500: The concrete solidifies to form the base plate 9.

[0034] Specifically, after the force transmission gasket 6 is placed, a synchronous pouring process is adopted to simultaneously pour concrete in the base plate formwork 7 on both sides of the force transmission gasket 6 to ensure that the concrete on both sides is evenly stressed and solidified synchronously; after the concrete pouring is completed, the connector 5, the pressing plate and the fixing plate 2 in the fixing assembly are removed in sequence, wherein the lubricating layer pre-applied on both sides of the fixing plate 2 can effectively reduce the removal resistance (in this embodiment, the lubricating layer is lubricating grease) to avoid damage to the concrete structure; finally, as Figure 4 and Figure 5 As shown, after the concrete is fully solidified, a complete base plate 9 structure is formed. At this time, the force transmission gasket 6 is tightly combined with the base plates 9 on both sides to form a continuous and stable force transmission system; the entire demolition process is operated with special tools to ensure construction safety and structural integrity.

[0035] Optionally, after step S500, the following steps are further included: S600: Remove the base plate template 7 and cut off the portion of the force transmission gasket 6 exposed on the base plate 9.

[0036] Specifically, after the concrete is completely solidified to form a structurally complete base plate 9, the base plate formwork 7 on both sides is first removed in an orderly manner. During the removal process, special attention should be paid to protecting the newly poured concrete structure. Subsequently, a special cutting tool is used to accurately remove the excess portion of the force-transmitting gasket 6 exposed on the surface of the base plate 9. The incision must be smooth and flush with the concrete surface. After this process is completed, the force-transmitting gasket 6 at the joint of the base plate 9 only retains the effective force-transmitting portion buried in the concrete, which not only ensures the neatness and beauty of the structure, but also maintains the integrity and functionality of the force-transmitting system. The entire removal process adopts a vibration-free cutting process to avoid damage to the solidified concrete structure.

[0037] Working principle: This application limits the length of the force transmission gasket 6 to extend into the first gap, so that the length of the force transmission gasket 6 is greater than the width of the base plate 9, thereby ensuring that it completely covers the joint area and effectively solves the problem of concrete cracks at the edge of the base plate 9 caused by multiple sections of the force transmission gasket 6 in traditional construction; at the same time, the left and right sides of the fixed component are tightened to achieve preliminary flatness in the vertical direction. Secondly, the two ends of the force transmission gasket 6 are sealed and abutted to achieve horizontal limitation, thereby ensuring the flatness of the force transmission gasket 6 on the entire plane, avoiding the occurrence of wrinkles, and also avoiding the problem of cracks caused by the concrete connection at both ends, thereby improving the ability and efficiency of the force transmission gasket 6 to transmit shear force, and improving the service life of the force transmission gasket 6.
