BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a storage hopper for aggregates such as silica sand and artificial sand, a tank for a binder mixed therein, and a series of devices such as a constant amount supply / conveyance device and a kneader. It is mounted on a low-floor railroad vehicle that runs on railroad tracks so that it can spread a certain thickness of kneading sand in any section between rails of railroad tracks, floor slabs, side roads, side walls, etc. The present invention relates to a railway vehicle-mounted sand kneading and spreading device capable of obtaining soundproofing and vibrationproofing effects from a railway track.

2. Description of the Related Art In recent years, along with the progress of speeding up of railway vehicles and strong demands of passengers, a railway line is three-dimensional and a straight line portion is relatively easy to obtain as compared with a land line which requires a level crossing, and Due to technical innovations such as the adoption of long rails, many viaduct tracks are adopted.By extension of these viaduct tracks, instead of installing rails on conventional wooden sleepers, rails can be directly installed on concrete sleepers or concrete roadbeds. The method of providing facilities is frequently used, and the speeding up of railway vehicles is becoming more and more advanced. Therefore, there are demands for improvement from the residents along the railroads regarding pollution such as noise and vibration generated by railway vehicles passing at high speed on the concrete roadbed of the viaduct, and various measures have been taken against this. There is something.

[0003] As a measure against pollution such as noise and vibration, a cushioning material is provided between the rail and the concrete roadbed to absorb the vibration, and the side wall of the viaduct line is also absorbed against the noise. Whether a noise blocking plate is erected on the part to prevent the noise from leaking to the outside directly, or various noise absorbing materials are installed inside the noise blocking plate to absorb the noise. Further, the entire upper opening of the viaduct line is covered with a dome shape to prevent noise from leaking to the outside.

However, among these pollution prevention measures,
In particular, even if a noise blocking plate is installed upright as a measure against noise, a sound absorbing material is installed inside the plate, and even if the entire upper opening of the viaduct is covered with a dome shape, noise can be leaked to the outside. ,
At the same time, it is unpopular because it also blocks passengers' vision from the car window, and in reality, it lacks a decisive measure as a noise prevention measure in view of the relationship with the invested capital.

Recently, as a part of such noise prevention measures, silica sand, artificial sand, etc. are provided on the rail-to-rail A, floor slab B, side road C and side wall D of the viaduct line Z as shown in FIG. As an aggregate, this is mixed with a binder, a curing agent, etc., and the sand is kneaded and spread so as to have a constant thickness, and is naturally cured,
Some experiments have been conducted to absorb noise by this kneading sand layer, and some have achieved some results.

However, in order to spread the kneaded sand to the entire area of the viaduct line Z except for the rails in which this experiment was performed, a replenishing device for a large-scale aggregate such as silica sand that is temporarily stored and supplied, and Since various auxiliary equipment such as storage equipment for binders and hardeners, and fixed quantity supply equipment to supply these to the kneading equipment secondarily are required, it is unavoidable that the track is close to the spread area. All of these replenishing devices, storage facilities, and ground-type kneading devices are arranged outside, and the kneaded sand is transferred to the spread area and the space A between the rails of the viaduct track Z, the floor slab B, and the side road. It is spread on the part C and the side wall part D so as to have a constant thickness. For this spreading work, it is necessary to spread a large amount of kneaded sand evenly before natural hardening. These spreading operations must be done promptly when there are no passing trains at night, and inevitably Work efficiency is limited to, or efficiently carried out in how this is what is the future.

[0007]

The problem to be solved by the present invention is to provide soundproofing between the railroad track A and rail interrail A, floor slab B, side road C, sidewall D, etc.
For the purpose of anti-vibration, the binder and hardener are mixed and kneaded to spread the sand to a certain thickness to prevent noise pollution from the railway line due to natural hardening. It is what

[0008]

Means for Solving the Problems The present invention is to spread a large amount of aggregates such as silica sand when a certain thickness of aggregate such as silica sand or artificial sand that is prepared by mixing a binder and a curing agent and kneading is spread. Storage equipment for binders and hardeners, and a series of kneading and spreading equipment such as kneading machines are placed on a low-floor railroad vehicle that runs on rails, and the railroad vehicles run and move on rails. On the other hand, the binder and the curing agent are mixed in appropriate amounts in the aggregate, the mixture is kneaded, and the aggregate is efficiently spread so as to have a constant thickness.

[0009]

According to the present invention, a low-floor railway vehicle is equipped with a large amount of aggregates such as silica sand, storage equipment for binders and hardening agents, and a series of kneading and spreading equipment such as kneaders. As a result, the pot life after kneading the aggregate until spreading (the self-hardening time that can be applied to the spread after adding a certain amount of binder and curing agent to the aggregate and kneading) and the curing time (automatic It is possible to freely set the required time until the hardness is completed and the original strength is exerted. Therefore, there is no time constraint such as work time taking into account the work time until the first train, and there is no need for efficiency. It is capable of humanized spreading work.
