Problems solved by technology

[0003] The purpose of the present invention is to: in the prior art, when the ballast track is used for rail transportation in the inclined shaft, the ballast track bed is easily deformed, and the maintenance workload is large; and the residual deformation of the ballast track accumulates quickly and Uneven deformation increases the risk of rail transportation operations in inclined shafts and reduces the efficiency of transportation operations. Provide a ballastless track for inclined shafts and its construction method

Embodiment 1

[0048] This embodiment provides an inclined shaft ballastless track, see Figure 1-6 , for viewing convenience, Figure 1-6 The track segments are all shown, the inclined shaft ballastless track includes a ballast bed 2, the ballast bed 2 is poured with concrete, and the ballast bed 2 is arranged on the bottom plate of the inclined shaft 1, which is the lower bottom of the inclined shaft On the slope surface, the ballast bed 2 is provided with a number of sleepers 3 and a number of stoppers 5, all of the sleepers 3 are used to support the rail 4, the lower part of the rail 4 is embedded in the ballast bed 2, and the stopper 5. One end is connected to the bottom plate of the inclined shaft 1, and the other end is connected to the steel rail 4.

[0049] In this embodiment, all the sleepers 3 include two rows arranged symmetrically, each row of sleepers 3 is connected to the bottom plate 1 of the inclined shaft at intervals along the longitudinal direction of the inclined shaft,...

Embodiment 2

[0056] This embodiment provides a construction method of the inclined shaft ballastless track as described in Embodiment 1, comprising the following steps:

[0057] Step 1: According to the design, stake out the track line on the bottom plate of the inclined shaft 1, and set the sleeper 3 on the bottom plate 1 of the inclined shaft according to the track line;

[0058] Step 2: laying two steel rails 4 on the corresponding sleepers 3 respectively;

[0059] Step 3: Connect several limiting parts 5 between the rail 4 and the bottom plate of the inclined shaft 1;

[0060] Step 4: Close the track bed formwork, pour the track bed 2, place the lower part of the rail 4, the sleeper 3 and the stopper 5 in the track bed 2, and the construction of the inclined shaft ballastless track is completed.

[0061] Specifically, the bottom surface of the inclined shaft is first leveled and cleaned to form the bottom plate 1 of the inclined shaft; in order to ensure the pouring quality of the bal...

Abstract

The invention relates to the technical field of tunnels and underground engineering, and especially relates to an inclined shaft ballastless track and a construction method thereof. The inclined shaftballastless track comprises a ballast bed, the ballast bed is arranged on an inclined shaft bottom plate, a plurality of sleepers and a plurality of limiting pieces are arranged in the ballast bed, the sleepers are used for supporting steel rails, the lower portions of the steel rails are embedded into the ballast bed, one ends of the limiting pieces are connected with the inclined shaft bottom plate, and the other ends of the limiting pieces are connected with the steel rails. The inclined shaft ballastless track is good in rigidity uniformity, long in service life and high in structural durability, the residual deformation cumulant of the steel rails is effectively reduced, irregular maintenance work caused by ballast bed deformation and steel rail deformation in the rail transportationoperation process is avoided, and the track investment cost of rail transportation operation is reduced.

Description

technical field [0001] The invention relates to the technical scheme field of tunnels and underground engineering, in particular to an inclined shaft ballastless track and a construction method thereof. Background technique [0002] In the construction of long tunnels, inclined shafts are usually used to increase the working face and speed up the construction progress. With the development of tunnel construction technology and the emphasis on ecological environment protection, the number of inclined shafts is gradually decreasing, and their length is gradually shortening. However, due to the constant depth, the slope of inclined shafts increases, and the construction tasks undertaken by inclined shafts Increase. At present, the inclined shaft generally adopts the ballasted track transportation system for transportation operations. Although the ballasted track is convenient to lay, during the tunnel construction process, the tunnel is frequently subjected to overweight trans...
