KR20000027951A - Filling material of open trench for protecting propagation of ground vibration using composite materials consisted of soft and hard materials - Google Patents

Abstract

PURPOSE: A filling material of an open trench is provided to protecting a propagation delivered from a vibration source on a ground channel. CONSTITUTION: A filling material of an open trench is produced by combining a concrete block(5) as a hard material with a soft material(4) by using a polyurethane degenerated epoxy resin adhesive. Herein, the soft material is made by compressing foaming rubber, foaming urethane, EPS, cork powder, and rubber powder. The concrete block contains a shape for conveniently assembling and maintaining shape and size and for preventing damage by the soil pressure of the soft material in the situation of increasing the depth of the open trench to intercept a ground vibration in a radio wave channel. Therefore, the open trench remarkably reduces human resources and cost used for maintaining and repairing compared to an existing wall for preventing the propagation of ground vibration.

Description

Dustproofing Filler for Ground Vibration Blocking Using Composite Material Combining Soft and Hard Materials

The present invention relates to a dustproof filling material using a composite material combining a ductile material and a rigid material, and more particularly, to a flexible material (4) compression-molding foam rubber and urethane, EPS, cork, and rubber powder. The present invention relates to an anti-vibration filler material invented for the purpose of blocking ground vibration propagation.

Among the various pollution problems, the problem caused by vibration causes a lot of complaints, which is reflected in the actual construction cost, and this phenomenon is expected to become more serious. In addition, due to the development of the industry, the scale of production facilities along with the social overhead capital facility has been increased and advanced, so that the vibration must be frequently solved to improve the quality of production. For example, in the case of a factory having vibration-sensitive equipment such as in a semiconductor factory, a facility for preventing the inflow of vibration from the outside is essential. In order to reduce the vibration causing such various problems, a method of preventing the generation of vibration itself from the vibration source that generates the vibration may be used. However, road traffic vibrations, railway vibrations, construction vibrations, etc. can not be prevented in many cases. Therefore, it is inevitable to use the method of preventing the inflow of vibration at the water vibration point or the method of blocking the vibration at the vibration propagation path. . The method of selecting one of the methods for solving the vibration problem is related to the characteristics of the generated vibration along with the type of the vibration source or the oscillation point, and in each case, the most efficient one is selected and used. As a countermeasure for minimizing the effects of various ground vibrations, a vibration barrier is installed to block the ground propagation of vibrations by reducing the permeation energy at the boundary by installing layers with different ground and impedance on the ground. It is used to reduce the effect of surface waves with most of the vibration energy on the water vibration point (structure, human body, precision equipment, etc.). In order to satisfy all the performance, safety, economics and workability required for the installation of the dustproof wall, it is required that the heterogeneous medium layer formed by the dustproof wall is significantly different from the surrounding ground density. In addition, safety of pedestrians should not be threatened and construction should be easy. Although the dustproof port (see FIG. 1 (a)) has been provided in accordance with the required performance of the dustproof wall, many effects have been provided, but problems arise in the maintenance and safety of the facility. Therefore, in the case of using the vibration barrier in the ground vibration propagation blocking method, a vibration blocking effect can be expected and a dustproof filler filling material which solves the above various disadvantages is required (see FIG. 1 (b)).

The present invention has been invented in view of the above-mentioned general problems, and an object of the present invention is to provide a dustproof filling material which can block the vibration propagated from the vibration source on the ground path. 1 is a combination of a flexible rubber (4) foamed or compression-molded foam material 4 and a concrete block 5 of a rigid material (5) to achieve this purpose, foamed or compressed urethane, EPS, cork, rubber powder It is to prevent the inflow of vibration at the water vibration point by blocking the ground vibration generated from the vibration source (1) in the vibration propagation path with the composite.
