Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a silo equipped with a precast RDM house and a guide slope, and a silo equipped with precast RDM houses and discharge inclines,

The present invention relates to a silo having a pre-cast RDM (Rotatory discharge machine) house and a guiding slope, and a method of constructing the silo. More specifically, the present invention can shorten the construction period of the silo, The present invention relates to a silo equipped with a precast RDM house and a guide slope, which can prevent detachment or detachment from the interior of the silencer, and can increase the coupling force.

Generally, a silo is a facility for storing granular materials such as coal and grains. It is composed of a foundation, a cylindrical wall, and a roof at the top. The silo is connected to the outer circumference of the wall to close the interior space of the silo, An inner cone formed in a cone shape so as to be able to be unloaded is partitioned into a plurality of spaces through a partition wall and an exit port is formed in the inner cone or space.

The wall of the silo is a cylindrical structure having a constant annular cross section, and in the case of a concrete silo, a slip foam capable of continuous casting and curing is applied, which is advantageous in terms of structural stability and air shortening.

The above slip foam is a method of continuously casting and pouring concrete by moving a certain shape of a mold through a hydraulic jack when a tower structure having a constant cross section such as a pier, a caisson, a suspension bridge or a pillar of a cable- To minimize the unnecessary joints and to produce an integrated structure. The mold assembly refers to a form assembly or a corresponding method.

These types of silos include tower silos, trench silos, bunker silos, stack silos, and vacuum silos. In Korea, tower silos are most popular.

The tower-type silo is a cylinder-shaped structure, and the material is generally composed of reinforced concrete. Such a tower type silo is classified into a hopper type silo, a flat type silo, and a companion silo depending on its shape.

Among them, the hopper-type silo is generally used because it has a cone-shaped bottom discharge part and is capable of natural discharge by gravity and can be installed in a large space in a small space as compared with a flat silo. Especially, the hopper type silo is mainly used when the input and discharge of the material is frequent.

In order to construct the hopper-type silo, a support structure for supporting the formwork and the formwork should be installed, and the concrete is laid on the upper part of the support structure and cured. The mold and support structure is a mold for curing hopper silos, and after construction is completed, all of them are disassembled and removed.

However, since the conventional hopper-type silo construction method is carried out in the field, it takes a lot of time to manufacture and install the formwork, to pour concrete and cure, to dismantle the formwork and the supporting structure, There was a problem in the quality control due to the variation of the construction quality depending on the skill level of the worker and the conditions of the site, and there was a safety problem due to the workers and the construction equipment as the internal work had to be carried out.

The above-mentioned invention means the background art of the technical field to which the present invention belongs, and does not mean the prior art.
