Abstract
The method of construction and repair of elevated railway orbit line that can be maintained is to install precast concrete slab constructed and installed on the base foundation with installed separation membrane, And a mold is installed around the slab so that the filler is injected into the penetration chamber to cure the railroad track. Since the elevated railway track capable of maintaining maintenance according to the present invention constructed as described above can reinforce the lower ground by additionally injecting a filler into the lower part of the precast concrete slab only lifted, There is an advantage that quick and easy coping is possible.
Description
The present invention relates to a method of constructing a railway track of a railway track capable of maintaining maintenance, and more particularly, to a method of railway track repair using a precast concrete block, The present invention relates to a railway track construction method for a railway track capable of maintaining maintenance by lifting a precast concrete block in response to a ground settlement, and to a railway track repair method using the railway track construction method.
Generally, the roads and railway tracks that are constructed through soft grounding are the most problematic due to the moving loads caused by long periods of operation of the vehicles or trains.
Since subsidence causes cracks and damage of asphalt roads and railway tracks, it acts as a main cause of car accidents and derailment accidents. In order to prevent such accidents and derailment accidents, maintenance costs for soft ground are increasing every year.
Especially, the underground concrete, which constitutes the railway track, affects the orbit itself composed of the rigid body due to the uneven settlement caused by the characteristics of the soft ground, and the deformation of the orbit is pointed out as the biggest problem causing the train derailment accident.
If the ground subsidence occurs in the railway track as described above, it is inevitable to repair it by lifting the track and reworking the lower ground or applying an expensive reinforcing method. In the case of the concrete ground of the railway track, the allowable residual settlement amount is strictly limited The settlement should be kept below the reference value by applying the settlement acceleration method or the settlement suppression method.
Conventional settlement promotion method is a method using drainage method and sand and crushing compaction pile method. It promotes the consolidation of ground and discharges groundwater in advance, so that no subsequent consolidation occurs.
The drain method is a method of promoting the consolidation by draining the groundwater into the soft ground and discharging the groundwater load. The sand and crushing compaction pile method is a method of promoting consolidation by piercing soft ground, pouring sand or crushed stone, and discharging groundwater by using overhead load.
However, since the existing settlement promotion method is a method for a soft ground suitable for civil engineering work with a large permissible residual settlement such as a harbor or a road, it is difficult to use it in a concrete track in which the allowable settlement is strictly limited, such as a railway track have.
Even if the railway track is constructed by applying the existing settlement acceleration method, it is necessary to perform repair work for the additional ground settlement to occur in the future. However, in the conventional repair methods, Therefore, there is a problem that the repairing process is complicated and the maintenance work period is prolonged.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a railway track construction method and a maintenance method capable of repairing a ground settlement occurring in a concrete ground of a railway track having a limited allowable settlement amount .
It is another object of the present invention to provide a railway track repairing method that can easily and efficiently perform a maintenance process for subsidence.
According to an aspect of the present invention, there is provided a method of constructing a railway orbit line using a precast concrete slab, the method comprising: A foundation ground construction step of constructing a foundation foundation; A slab installing step of aligning the precast concrete slab on an upper surface of the foundation foundation; And a finishing step of finishing the precast concrete slab by connecting a rail to the precast concrete slab, and closing the precast concrete slab.
The precast concrete block of the present invention comprises: a slab structure formed of a rectangular plate; A plurality of slits formed on the upper surface of the slab structure, and a through chamber formed through the upper and lower surfaces of the slab structure.
Preferably, the penetration chamber of the present invention further includes a maintenance chamber which is formed by being embedded from the bottom of the penetration chamber to the inner side.
The foundation ground construction step of the present invention includes a lower ground construction step of forming a lower ground by casting abandoned concrete after the ground compaction step; A shear key construction step of installing a shear key at a predetermined distance on the upper surface of the lower ground, and a separation membrane forming step of forming a separation membrane in the lower ground or the shear key.
The slab installing step includes a slab position adjusting step of finely adjusting a position of the precast concrete slab which is seated on a foundation foundation by a moving facility, and the slab positioning adjustment step is a step of adjusting the position of the precast concrete slab, The horizontal position is finely adjusted by a horizontal adjusting device which is supported by the supporting block and the side surface of the precast concrete slab so as to reduce or increase the interval therebetween and is screwed into the through hole formed in the precast concrete slab It is preferable to finely adjust the position in the vertical direction by the vertical adjusting device configured to move up and down.
The filling material placing step of the present invention includes disposing the molds at a predetermined distance from the outer surface of the precast concrete slab and forming a transverse side film to prevent the filling material from being poured at a point where the precast concrete slabs are connected to each other. As shown in Fig.
In the filling step of the present invention, it is preferable to inject the filler through the penetration chamber, and an additional barrier or a barrier is installed in the maintenance chamber so as not to inject the filler.
There is provided a method of repairing a railway track installed by a maintenance method of a railway track of a height adjustable type according to the present invention, Installing a form around the precast concrete slab; A slab lifting step of lifting the precast concrete slab; And injecting a filler through the penetration chamber of the precast concrete slab.
The method may further include a filler crushing step of crushing and partially curing the cured filler placed in the penetration chamber of the precast concrete slab after the preliminary preparation step of the present invention.
In the slab lifting step of the present invention, it is preferable that a hydraulic jack is installed in the maintenance chamber in the penetration chamber through the space where the filler is crushed to lift the pre-cast concrete slab, and then lifting the slab.
According to the method for constructing a railway track of a height adjustable type according to the present invention and a railway track repair method using the railway track construction method, it is possible to rapidly construct a precast concrete slab, It has a merit and short construction period and since it can reinforce the lower ground by lifting only the precast concrete slab after completion of the construction, there is an advantage that it can respond quickly to the partial settlement of the ground.
