Description

Technical Field

[0001] The invention relates to the field of rail transportation, and in particular to a rail pavement structure. Background Art

[0002] The existing track pavement on both sides of the guide rail is generally directly paved with cement grouting on both sides of the track to form a cement pavement. This type of track pavement has two main problems. Various factors on site will cause the grouting height on both sides to be inconsistent, resulting in inconsistent pavement height on both sides of the guide rail; long-term use will cause the pavement to be concave and uneven.

[0003] In view of this, the present invention is proposed. Summary of the invention

[0004] The purpose of the present invention is to provide a track pavement structure which can solve the problem that cement pavements are used on both sides of the existing track, resulting in inconsistent heights and uneven pavement caused by long-term use.

[0005] The objective of the present invention is achieved through the following technical solutions:

[0006] An embodiment of the present invention provides a track pavement structure, comprising:

[0007] Cement foundation, two sets of height-adjustable steel plate embedded components, two embedded pits and guide rails; among them,

[0008] The guide rail is fixedly laid on the cement foundation;

[0009] A pre-buried pit is provided on the cement foundation on both sides of the guide rail, and a group of height-adjustable steel plate pre-buried components is laid in each pre-buried pit;

[0010] There is a height difference between the upper plane of each group of height-adjustable steel plate embedded components and the upper plane of the embedded pit, and a grouting space is provided inside each group of height-adjustable steel plate embedded components.

[0011] Compared with the prior art, the track pavement structure provided by the present invention has the following beneficial effects:

[0012] By setting up embedded pits in the cement foundation on both sides of the guide rails and arranging height-adjustable steel plate embedded components in the embedded pits, the problems of uneven road surface and uncontrollable height difference on both sides caused by insufficient precision in civil construction are solved. In addition, since the height-adjustable steel plate embedded components can adopt the structural form of steel plates, the wear resistance is improved, the problem of uneven road surface caused by long-term use of cement pavement is solved, and the maintenance rate of the track pavement is reduced.

[0027] Cement foundation 1, two sets of height-adjustable steel plate embedded components 2, two embedded pits 3 and guide rails 4; among them,

[0028] The guide rail 4 is fixedly laid on the cement foundation 1;

[0029] The cement foundation 1 on both sides of the guide rail 4 is provided with a pre-buried pit 3, and a group of height-adjustable steel plate pre-buried components 2 are laid in each pre-buried pit 3;

[0030] There is a height difference between the upper plane of each set of height-adjustable steel plate embedded components 2 and the upper plane of the embedded pit 3, and a grouting space is provided inside each set of height-adjustable steel plate embedded components 2. The height of the upper plane of each set of height-adjustable steel plate embedded components 2 can be adjusted to form a height difference with the upper plane of the embedded pit 3.

[0031] In the above structure, the two sets of height-adjustable steel plate embedded components 2 have the same structure, both consisting of multiple sets of height-adjustable frame steel plate sub-components;

[0032] Each set of height-adjustable frame steel plate subassemblies includes:

[0033] Height-adjustable channel steel frame 21 and road surface steel plate 22; wherein,

[0034] The height-adjustable channel steel frame 21 is fixedly laid in the pre-buried pit 3;

[0035] The pavement steel plate 22 is laid on the height-adjustable channel steel frame 21 , and the top surface of the pavement steel plate 22 is the upper surface of the height-adjustable steel plate embedded component 2 .

[0036] In the above structure, the height-adjustable channel steel frame 21 is composed of a plurality of channel steel frame blocks 211 and a plurality of height-adjusting rods 212;

[0037] The bottom of the channel steel frame block 211 is fixed in the embedded pit 3;

[0038] The four corners of the channel steel frame block 211 are all provided with height adjustment rods 212; if there are multiple channel steel frame blocks 211, four height adjustment rods 212 are provided on each channel steel frame block 211, and a steel plate 221 of a road steel plate 22 is correspondingly installed on each channel steel frame block 211;

[0039] The bottom end of the height adjustment rod 212 is fixed in the embedded pit 3, and the upper end is fixed to the channel steel frame block 211 through a nut, so that the height can be adjusted up and down.

[0040] The height adjustment rod 212 adopts a screw structure. By setting the height adjustment rod 212, the height of the road surface steel plate 22 installed above can be conveniently adjusted.

[0041] In the height-adjustable frame steel plate subassembly, the road surface steel plate 22 is composed of a plurality of steel plate blocks 221 , and each steel plate 221 is laid on the height-adjustable channel steel frame 21 in sequence.

[0042] The steel plate 221 is provided with grouting holes 2211 and ventilation holes 2212 .

[0043] In the above structure, the guide rail 4 is fixedly laid at the center position of the cement foundation 1 .

[0044] In the above structure, the distances between the pre-buried pits 3 on both sides of the guide rail 4 and the guide rail 4 are equal.

[0045] In summary, the track pavement structure of the embodiment of the present invention adopts a height-adjustable channel steel frame combined with a pavement steel plate to form a height-adjustable frame steel plate subassembly, and a plurality of groups of height-adjustable frame steel plate subassemblies form a height-adjustable steel plate embedded assembly. During the installation process, the height adjustment rod is used to facilitate the adjustment of the left and right channel steel frames, ensuring the height consistency between the height-adjustable steel plate embedded assembly and the cement foundation, achieving quick and effective left and right height adjustment, improving work efficiency, and reducing the rework rate of track pavement filling; at the same time, the pavement of the steel plate structure also improves wear resistance and reduces the maintenance rate of the track pavement. The slurry with a dilution ratio of strong fluidity is injected through the steel plate grouting port of the pavement steel plate, thereby achieving effective filling of the slurry. Combined with the pavement steel plate, it well solves the problem of the existing cement track pavement being easily damaged due to long-term use, resulting in uneven pavement.

[0046] In order to more clearly demonstrate the technical solution and technical effects provided by the present invention, the branch road device provided by the embodiment of the present invention is described in detail with reference to a specific embodiment below. Example

[0047] like Figure 1 , 2 As shown, an embodiment of the present invention provides a track pavement structure suitable for use as a track pavement for a sightseeing bus or other transport vehicles, comprising: a cement foundation 1, a height-adjustable steel plate embedded component 2, an embedded pit 3 and a guide rail 4; wherein,

[0048] The guide rail 4 is fixed at the center of the cement foundation 1, and the pre-buried pits 3 are located on the left and right sides of the guide rail 4 and are distributed at equal distances from the center of the guide rail 4;

[0049] The height-adjustable steel plate embedded component 2 is composed of multiple groups of height-adjustable frame steel plate sub-components, each group of height-adjustable frame steel plate sub-components includes: a height-adjustable channel steel frame 21 and a pavement steel plate 22; the height-adjustable channel steel frame 21 is embedded in the embedded pit 3, and the pavement steel plate 22 covers the height-adjustable channel steel frame 21; the upper plane of the pavement steel plate 22 can be maintained on the same horizontal plane as the upper plane of the cement foundation 1, and the height difference can also be set as needed.

[0050] The height-adjustable channel steel frame 21 is composed of a channel steel frame block 211 and a plurality of height-adjusting rods 212; the length of the channel steel frame block 211 is set according to actual needs, and height-adjusting rods 212 are distributed at the four corners of each channel steel frame block 211; the height-adjusting rod 212 is a screw structure, the bottom end of which is fixed in the embedded pit 3, and the upper end is fixed to the channel steel frame block 211 by a nut. When adjusting the overall assembly, a wrench is used to adjust the upper nut to achieve height adjustment of the channel steel frame block 211.

[0051] The height adjustment rod 212 may be fixed by providing a through hole on the frame of the channel steel frame block 211 , or by providing a fixed platform at the inner frame corner of the channel steel frame block 211 .

[0052] The road surface steel plate 22 is composed of a plurality of steel plates 221, each of which is provided with a grouting hole 2211 and a vent hole 2212. The length of each steel plate 221 can be set according to actual needs.

[0053] The guide rail 4 is fixed to the center of the cement foundation 1, and pre-buried pits 3 are set at equidistant positions on both sides thereof. The height-adjustable steel plate pre-buried component 2 is embedded in the pre-buried pit 3. During the installation process, the height-adjustable steel plate pre-buried component 2 is installed in a block-by-block manner. The channel steel frame block 211 is installed in blocks into the pre-buried pit 3. The height of the channel steel frame block 211 is adjusted by the height adjustment rod 212, and the joints of each channel steel frame block 211 are fixed into one. After the installation of the left and right channel steel frame blocks 211 is completed, the steel plate 221 is installed in blocks to the channel steel frame blocks 211. On the steel frame block 211, keep the upper plane of the left and right height-adjustable steel plate embedded components 2 and the upper plane of the cement foundation 1 at the same level. If some positions are not at the same level, open the steel plate 221 at the corresponding position, and then adjust the height of the channel steel frame block 211 at the corresponding position through the height adjustment rod 212 until the upper plane of the road surface steel plate 22 and the cement foundation 1 are at the same level. After the height adjustment is completed, weld the road surface steel plate 22 to the channel steel frame 21. By setting the height adjustment rod, the height of the left and right height-adjustable steel plate embedded components on the guide rail can be quickly, accurately and effectively achieved, solving the problem of uneven road surface and uncontrollable height difference on both sides caused by insufficient precision in existing civil construction;

[0054] After the height adjustment and welding of the channel steel frame 21 and the road surface steel plate 22 are completed, the slurry with a high fluidity is diluted and injected into the height-adjustable steel plate embedded assembly through the grouting hole 2211 to achieve the slurry filling in the channel steel frame 21. By injecting slurry into the road surface steel plate and combining the road surface steel plate, the problem of uneven road surface caused by long-term use of cement road surface is solved.

They constitute height-adjustable steel plate embedded components, which enhance wear resistance, increase service life and reduce maintenance rate.
