Description

Inclined shaft track-laying bed

Technical Field

The utility model relates to a ballast bed, especially a ballast bed for inclined shaft.

Background

The track-laying track bed in the existing inclined shaft is a concrete integral track bed, the track bed comprises an integral concrete layer and a baffle plate arranged on the concrete layer, the baffle plate is fixedly connected with a track through a bolt, and an anchor rod embedded in the concrete layer can block the baffle plate to achieve the purpose of skid resistance.

The defects of the prior ballast bed are as follows: the construction cost is high in the early stage, the concrete consumption is large, the construction difficulty in the inclined shaft is large, and the construction period is long.

SUMMERY OF THE UTILITY MODEL

The utility model provides a track bed is spread to inclined shaft, its purpose: the concrete consumption is reduced, the construction difficulty and cost are reduced, and the construction period is shortened.

The utility model discloses technical scheme as follows:

a rail paving bed for an inclined shaft comprises a bottom plate paved at the bottom of the inclined shaft and sleepers connected with rails, wherein a plurality of concrete retaining walls are arranged on the bottom plate at intervals along the paving direction of the rails, anchor rods are buried in the bottom plate, and the upper ends of the anchor rods are positioned in the concrete retaining walls; the upper end of each concrete retaining wall protrudes out of the bottom plate, the top of each concrete retaining wall is provided with an inclined steel plate, and the top of each steel plate is connected with the bottom of the track;

the inclined shaft track laying bed further comprises ballast paved on the bottom plate and sleepers placed at the tops of the ballast.

As a further improvement of the inclined shaft track-laying bed: be equipped with steel reinforcement framework in the concrete barricade, steel reinforcement framework's bottom with stock fixed connection, the top with steel sheet fixed connection.

As a further improvement of the inclined shaft track-laying bed: and a slope is arranged on one side, close to the bottom end of the inclined shaft, of the top of the concrete retaining wall.

As a further improvement of the inclined shaft track-laying bed: the embedding depth of the anchor rod is not less than 1000mm.

Compared with the prior art, the utility model discloses following beneficial effect has: (1) The novel ballast bed adopts the concrete retaining walls arranged at intervals to replace the traditional integral concrete ballast bed, so that the concrete consumption is low, the construction difficulty is low, the construction period is short, and the cost is low; (2) The bottom of the concrete retaining wall is fixed with the bottom plate through the anchor rod, the top of the concrete retaining wall is fixed with the track through the steel plate, the anti-skidding effect is good, and the track is not easy to deform; (3) The track is divided into a plurality of independent areas by the concrete retaining walls arranged at intervals, and only construction is needed among the concrete retaining walls when the ballast is laid or the track is adjusted, so that time and labor are saved; (4) The slope design on the concrete retaining wall can reduce the contact area of the steel plate and the track under the conditions of ensuring the size of the root of the concrete retaining wall and improving the stability, the installation and connection are convenient, the adjustment of the track is realized, and the concrete material is further saved.

Drawings

FIG. 1 is a schematic view of the structure of the present invention applied in a slant well;

fig. 2 is a partially enlarged view of a portion a in fig. 1.

Detailed Description

The technical scheme of the utility model is explained in detail in the following with the attached drawings:

referring to fig. 1 and 2, a slant well track-laying bed comprises a bottom plate 6 (usually hard rock) laid on the bottom of a slant well, and a crosstie 3 (including tie plates and spikes) for connecting to a track 2.

A plurality of concrete retaining walls 5 are arranged on the bottom plate 6 at intervals along the laying direction of the track 2, anchor rods 7 are buried in the bottom plate 6, and the upper ends of the anchor rods 7 are located in the concrete retaining walls 5 and fixedly connected with the steel reinforcement frameworks inside the concrete retaining walls 5.

Further, be provided with a plurality of openings with concrete retaining wall 5 one-to-one on bottom plate 6, the latter half of each concrete retaining wall 5 is located the opening, stock 7 then buries underground in each open-ended bottom.

The upper end of each concrete retaining wall 5 is protruded out of the bottom plate 6 and the top is provided with an inclined steel plate 1, and the steel plate 1 is also fixedly connected with a steel reinforcement framework and connected with the bottom of the track 2.

Preferably, 5 top of concrete retaining wall are close to one side of inclined shaft bottom and are equipped with the slope, guaranteeing 5 root sizes of concrete retaining wall, improving under the condition of steadiness, reduce steel sheet 1 and track 2's area of contact, and the concrete material has been saved with orbital adjustment to easy erection joint.

The inclined shaft track-laying track bed further comprises ballast 4 laid on the bottom plate 6 and sleepers 3 placed at the tops of the ballast 4, the tops of the ballast 4 and the sleepers 3 are flush with the top of the steel plate 1, and the inclination is kept consistent with the angle of the inclined shaft.

The construction process is as follows:

firstly, measuring and placing points, determining the position of the concrete retaining wall 5 to be constructed, constructing an opening, and cleaning the concrete retaining wall to the bottom plate 6. Then installing a rooting anchor rod 7, wherein the embedding depth of the anchor rod 7 is not less than 1000mm. And binding the steel reinforcement framework, and then welding the steel plate 1 and the steel reinforcement framework together. During construction, all the steel plates 1 are ensured to be on the same plane and consistent with the angle of the inclined shaft. And after all the steel bars and the steel plates 1 are constructed, uniformly pouring the concrete retaining wall 5. Then paving the ballast 4 and the sleepers 3 according to the construction specification, and finally installing the rails 2 to be fixed with the sleepers 3 into a whole.
