Three-dimensional water discharge coupling button apparatus

Abstract

The invention relates to a three dimensional water draining connecting tab device, which comprises a base plate and projections formed on two sides of the base plate, wherein, a three dimensional water draining passage is arranged on the base plate. In the invention, the three dimensional water draining passage comprises a drain hole penetrating the two sides of the base plate, a first drain tankarranged on one side of the base plate and extended along the base plate, and a second drain tank arranged on the other side of the base plate and extended in the direction crossing the extending direction of the first drain tank. Through the structure, a three dimensional full dimensional water draining structure is formed on the base plate. The drain hole and the drain tanks further increase thefriction factor of the surface of the base plate, so as to increase the tensile resistance and shearing strength of a junction, and, moreover, the junction has the characteristics of tensile resistance, bending resistance and multi-surface distortion resistance, so that the connecting tab structure is more flexible. In addition, the three dimensional passage further provides a non-disturbance growth passage for plant root systems, thus facilitating free growth and penetration of the plant root systems.

Description

【Technical field】 [0001] The invention relates to a coupling buckle device, in particular to a three-dimensional drainage coupling buckle device for building retaining walls. 【Background technique】 [0002] Retaining walls are widely used in various civil engineering projects, such as slopes to support roads or river embankments, and free-standing walls. Current retaining wall structures use sandbags to replace the wall structure, and then backfill or fill with other substances. The strength and toughness of the retaining wall are very important. A retaining wall with low strength and poor toughness may cause major accidents or casualties. Therefore, it is necessary to develop a high-strength retaining wall that can resist harsh environments without being damaged. . [0003] For example, Taiwan Patent TW 480301 titled "Retaining Wall System with Interlocking Wall Units" discloses a method of constructing a retaining wall using wall units such as sand / soil bags or hardenabl...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the technical problem that the interlocking components used to connect the building units of the retaining wall do not have a drainage structure, which is not conducive to the discharge of accumulated water in the retaining wall in the prior art, the present invention provides a connecting member with a three-dimensional drainage channel. buckle device

In addition, the present invention further solves the technical problem in the prior art that the wall building unit is easy to slide or disengage from the interlocking member by improving the protrusion structure
