Description

Settlement adjustment method and system suitable for ballastless track with shoulder

Technical Field

The invention belongs to the technical field of rail transit, and particularly relates to a settlement adjusting method and system suitable for a ballastless track with a shoulder.

Background

In recent years, China's high-speed railways have attracted attention, and by the end of 2019, China's high-speed rail operation mileage exceeds 3.5 kilometers, occupies more than two thirds of the mileage of the world's high-speed railways, and stably lives in the first of the world.

With the increase of the operation mileage lines, the maintenance amount of the lines is also increased, and new maintenance problems are caused. Taking maintenance and repair of a track as an example, at present, a ballastless track structure form is mainly adopted by a high-speed railway in China, and due to the particularity of the ballastless track structure, the geometric dimension of the track can be limited and adjusted only through a fastener system in the line operation period. Although a high-speed railway is constructed by adopting a higher construction standard and corresponding construction measures, the problems of ballast bed settlement or track gauge change and the like can occur in the later operation process. Once the post-construction settlement of the ballastless track or the track gauge variation of the track exceeds the adjustment capability of the fastener system, the geometric state of the track is difficult to repair, so that the train has to travel at a limited speed, and the normal operation of the line is seriously influenced.

At present, in order to repair the geometric state of a ballastless track timely and effectively, recover the high smoothness of a line and ensure the safe operation of a train, a grouting method is generally adopted for large post-construction settlement, and the whole foundation under the track is lifted by the grouting method so as to complement the settlement of the track. Although the method can solve the problem of uniform settlement of the undersized foundation to a certain extent, the method cannot meet the adjustment requirement of the undersized foundation during the non-uniform settlement, and cannot realize larger adjustment of the rail in the transverse direction. In addition, the method needs specially-made construction equipment, is complex in process and high in maintenance cost, and indirectly improves the operation cost of the high-speed railway.

Correspondingly, the waist-shaped distance adjusting ring 5 in the preferred embodiment comprises a body which can be correspondingly embedded into the waist-shaped bolt hole 102 and is in a long waist-shaped structure, the middle part of the body is vertically provided with a circular through hole for the bottom of the screw spike 301 to pass through, and a concentric distance adjusting ring 501 as shown in fig. 6 and an eccentric distance adjusting ring 502 as shown in fig. 7 can be formed by the positions of the circular through hole and the axis of the body. In the concentric distance adjusting ring 501, the axis of the circular through hole and the axis of the body are in the same vertical plane along the longitudinal direction, and the circular through hole and the body are preferably arranged in a collinear way; in the eccentric adjustment ring 502, the axis of the circular through hole is spaced a distance l from the axis of the body in the transverse direction of the rail 10, preferably in the transverse direction, with an eccentric orientation, as shown in fig. 7. It should be noted that, in the preferred embodiment, the eccentricity orientation refers to a direction in which the center of the circular through hole is directed toward the center of the body, that is, the eccentricity orientation in fig. 7 is a direction directed to the left.

In practice, the waist rings 5 are arranged in pairs in the transverse direction, and the number of pairs of the waist rings 5 arranged in the longitudinal direction is at least one pair, for example two pairs as shown in fig. 8. Of course, the number of pairs of the waist rings 5 may be multiple in order to achieve stable connection of the base 1. Further, when the pair of concentric distance rings 501 is replaced with the pair of eccentric distance rings 502, the lateral distance between the eccentric distance rings 502 is equal to the lateral distance between the concentric distance rings 501 when they are arranged in pairs. In addition, according to the needs of practical application, the eccentric distance adjusting ring 502 can be set to be selectable in various sizes, and the eccentric distance l of each eccentric distance adjusting ring 502 is different, and further 1-15 mm can be preferred.

Further, the elastic strip fastening assembly 2 in the preferred embodiment comprises a T-shaped bolt 201, a washer 202 and a fastening nut 203, wherein the T-shaped bolt 201 can penetrate through the bottom of the elastic strip fastening hole 103 and extend upwards to match with the fastener 8, and the elastic strip is further compressed by the fastening nut 203 and the washer 202. In order to fix the nut end of the T-bolt 201 and prevent the T-bolt 201 from rotating, the elastic strip fastening hole 103 in the preferred embodiment is a stepped hole, the diameter of the hole on one side close to the bottom surface of the base 1 is larger than the diameter of the hole on the other side, and a limiting boss 105 is arranged in the stepped hole, as shown in fig. 5, so that the nut of the T-bolt 201 abuts against the limiting boss 105 and is locked in the circumferential direction.

Further preferably, an insulating shock-absorbing pad 4 is provided at the bottom of the base 1 for insulating and absorbing shock at the bottom of the base 1. The upper and lower surfaces of the insulating shock pad 4 are preferably pitted to enhance the friction between the upper and lower contact surfaces.

The settlement adjusting system is used for adjusting the height and the track gauge of the ballastless track settlement section with the shoulder, and the steps preferably comprise:

(1) a cast-in-place boss 6 is arranged on a track bed 9 of a ballastless track settlement section and is correspondingly arranged between two retaining shoulder rail bearing platforms 7.

Specifically, the track bed 9 between the two shoulder bearing rail platforms 7 is cleaned, holes are correspondingly drilled in the track bed 9 according to the distance between the kidney-shaped bolt holes 102 at the two ends of the base 1, insulation sleeves 302 are correspondingly preset in the drilled holes, and the length of the insulation sleeves 302 protruding out of the top surface of the track bed 9 is equal to the cast-in-place height of the cast-in-place boss 6. And then, casting and molding the cast-in-place boss 6 on the ballast bed 9, and performing a subsequent adjusting process after molding.

(2) An insulating shock pad 4 with a certain thickness is arranged on the top surface of the cast-in-situ boss 6, and a base 1 is arranged above the insulating shock pad 4.

Before the base 1 is arranged, each T-shaped bolt 201 penetrates through the corresponding elastic strip fastening hole 103 from the lower part of the base 1, and the nut of the T-shaped bolt 201 is limited annularly by the limiting boss 105. Further, waist shape roll adjustment ring 5 is set up respectively in each waist shape bolt hole 102 for the circular through-hole of each waist shape roll adjustment ring 5 is vertical with the coaxial alignment of the corresponding insulation support 302 of pre-buried setting, and then passes waist shape roll adjustment ring 5 and insulating shock pad 4 from top to bottom in proper order with the link (being the bottom) of each spiral spike 301, and mating connection is in insulating sleeve 302, and until the terminal surface of the cap butt base 1 of pressing of spiral spike 301, compress tightly base 1 on cast-in-place boss 6.

Preferably, when the cast-in-place boss 6 and the base 1 are arranged, the track gauge adjustment distance of the steel rail 10 can be taken into consideration, and in this case, the waist-shaped distance adjusting rings 5 are concentric distance adjusting rings 501 arranged in pairs. Once the rail gauge of the steel rail 10 changes after the settlement adjustment system is set, the concentric distance adjusting rings 501 can be replaced by the eccentric distance adjusting rings 502 in pairs, so that the subsequent rail gauge adjustment can be realized.

(3) The fastener 8 is correspondingly arranged between the two shoulder pads 101 of the base 1, and preferably comprises a plurality of rail lower backing plates, insulating gauge blocks, elastic strips, insulating stop blocks and other structures as shown in fig. 1 and 2, namely, the fastener 8 available on the existing shoulder pad rail bearing platform 7 is adopted. And then the elastic strip is pressed on the insulating track gauge block through the two T-shaped bolts 201 respectively matched with the gasket 202 and the buckling nut 203, and the steel rail 10 is pressed on the base through the two insulating track gauge blocks, so that the adjustment of the height and the track gauge of the steel rail 10 in the subsidence section of the track bed is completed, and the structural schematic diagram of the adjusted track is shown in fig. 12.

Obviously, when the adjusted steel rail 10 has a height adjustment requirement in the subsequent operation process, the height adjustment can be realized by replacing the corresponding rail lower base plate in the fastener 8; moreover, the subsequent adjustment of the rail 10 can also be achieved by replacing or adjusting the relevant components of the fastener 8, such as replacing the insulating gauge block or adjusting the insulating gauge block, and such adjustment is similar to the adjustment process of the conventional fastener system and therefore not described in detail herein. In addition, settlement adjustment system in this application, it also can regard as the fastener system alone to use on ballast bed 9, and the setting process is similar with above-mentioned process, and the flexibility that entire system set up convenient, adjusted is big, has still saved the corresponding setting of fender shoulder bearing rail 7 on the ballast bed.

Further, when the track gauge of the adjusted steel rail 10 changes during the subsequent operation, the adjustment of the track gauge can be realized by the adjustment process as shown in fig. 11.

For example, the settlement adjustment system of the track bed 9 arranged along the track in the transverse direction is shown in the uppermost diagram of fig. 11, i.e. the track gauge of the two rails is 1435 mm. At this time, if the rail 10 on the right side needs to be adjusted to the right side by 5mm, the concentric distance adjusting rings 501 on the settlement adjusting system on the right side may be replaced with eccentric distance adjusting rings 502 having an eccentric distance of 5mm, respectively, and the eccentricities of all the eccentric distance adjusting rings 502 face the right, that is, the track distance adjusting direction and the eccentricity direction are the same. Similarly, if the rail 10 on the left side needs to be adjusted to the left by a track gauge of 5mm, the adjustment method is similar to the above process, that is, the eccentric distance ring 502 with the eccentricity toward the left and the eccentric distance of 5mm is replaced in the settlement adjustment system on the left side.

Of course, when the track pitches of the two rails 10 need to be reduced, the adjustment method is similar, and only the eccentric pitch direction of the eccentric pitch adjusting ring 502 needs to be correspondingly changed. In addition, the concentric distance adjusting rings 501 in the two settlement adjusting systems arranged at intervals in the transverse direction of the ballast bed 9 can be replaced by the eccentric distance adjusting rings 502 according to the requirements, and the directions of the eccentricities of the two groups of eccentric distance adjusting rings 502 can be the same or different; when the directions of the eccentricity are different, the directions of the eccentricity can deviate from each other and can also be arranged in opposite directions. The adjusted gauge is the largest (e.g., 1445mm as shown) when the eccentricities are facing away from each other, and the adjusted gauge is the smallest (e.g., 1425mm as shown) when the eccentricities are facing each other. It should be noted, however, that the eccentric distances of the eccentric distance adjusting rings 502 on the same base 1 are the same, and the eccentric distances of the eccentric distance adjusting rings 502 are the same.

The settlement adjusting system suitable for the ballastless track with the shoulder is simple in structure and simple and convenient to set, can accurately realize the rapid settlement adjustment of the ballastless track bed settlement section with the shoulder, accurately realize the height adjustment and the gauge adjustment of the steel rail, and improve the efficiency and the accuracy of the settlement adjustment of the track bed; meanwhile, through the kidney-shaped bolt holes formed in the base and the kidney-shaped distance adjusting rings arranged corresponding to the kidney-shaped bolt holes, the corresponding adjustment of the rail gauge of the steel rail after the settlement adjusting system is arranged can be realized through the replacement of the concentric distance adjusting rings and the corresponding eccentric distance adjusting rings, the efficiency and the accuracy of the rail gauge adjustment of the steel rail are further improved, the reliable application of the ballastless track with the shoulder is ensured, the application cost of the ballastless track with the shoulder is reduced, and the method has a better application prospect and popularization value.
