Description

Assembled type earthquake-proof retaining wall building block system

Technical Field

The invention relates to an assembled type anti-seismic retaining wall block system, in particular to an assembled type anti-seismic retaining wall block system which is combined in an improved meshing mode, increases the bonding force among blocks and has an improved structure for further stabilizing and rapidly building a retaining wall in a one-point-to-one building mode.

Background

At present, along with the change of global environment and frequent occurrence of earthquakes, the retaining wall is easy to collapse, so that the lives and properties of people are damaged, and the earthquake-resistant design of buildings becomes more important.

Building construction, building (civil engineering) works such as roads and railways are so-called cutting for excavating a foundation higher than the surroundings, and so-called embankment construction for building a foundation with sand and soil piled up to increase the height of the foundation. The large slope formed by cutting and embankment is easy to be damaged by rainfall or earthquake, resulting in the easy collapse of the large slope. Such inclined surfaces, i.e., slope surfaces, are generally provided with wall-shaped building structures, i.e., retaining walls, to prevent collapse.

The retaining wall is a wall structure that can resist earth pressure and prevent earth from collapsing. The reinforced earth is piled up on the foundation at the lower part to prevent the collapse of the reinforced earth. Generally, a concrete retaining wall or retaining wall blocks are used to construct a retaining wall, and the concrete retaining wall is usually constructed by a wet construction method, so that the construction time is difficult to reduce, the labor cost is high, and the construction cost is easily increased.

To solve these problems, a retaining wall, which is a wall-shaped building structure, is provided on an inclined surface, i.e., a slope surface, to prevent collapse. Korean registered utility model No. 20-0425520 (hereinafter, referred to as "prior art document") proposes a block type reinforced earth retaining wall connection structure.

The reinforced earth retaining wall disclosed in the prior art document is such that when the reinforced earth blocks are laid upward, the front ends of the rib materials of the geogrid are sandwiched between the reinforced earth blocks laid upward and downward. The reinforced earth block is characterized in that the upper and lower reinforced earth blocks are connected and laid by the connecting devices in a state that the connecting devices are clamped on the clamping grooves, the connecting devices are arranged in a penetrating manner from the front end of the geogrid reinforcement, and the reinforced earth block is characterized in that the upper and lower reinforced earth blocks to be laid are fixed on the geogrid reinforcement through the connecting devices.

Technical scheme

In order to achieve the above object, the present invention provides a block for building a retaining wall having a coupling projection and a coupling groove on a side surface thereof, comprising: a first joining projection (110) and a second joining projection (120) formed together on each of four surfaces of four corner side surfaces of a main block (100), and a first joining groove (130) joined to the first joining projection and a second joining groove (140) joined to the second joining projection (120); a through groove 170 provided in the center of the main block 100 and vertically penetrating the main block 100; a drainage groove (150) which is arranged in a cross shape on the upper surface of the main building block (100); two upper fixing pin grooves (210, 220) provided on the upper surface of the main block (100) so that the lower portion of a fixing pin (230) for connecting and fixing the upper and lower blocks can be inserted when the main block (100) is laid up; and a lower fixing pin groove (160) which is provided below the main block (100) in parallel with a straight line connecting the two upper fixing pin grooves (210, 220), has a straight line of four-corner grooves, has a center line closer to the inner side of the main block (100) than the straight line connecting the two upper fixing pin grooves in a plan view, and allows the upper part of the fixing pin (230) to be inserted. Thus, the upper blocks (320) of the continuously built retaining wall blocks are installed more to the rear side of the retaining wall than the lower blocks (310) by building inward.

In a preferred embodiment, the length of the fixing pin (230) is 9.5 to 10cm, the thickness or diameter of the fixing pin (230) is 1cm, the diameter of the upper fixing pin groove (210, 220) is 1.2 to 1.5cm, the depth is 8cm, the height of the lower fixing pin groove (160) is 3cm or less, and the width is 2 to 2.5 cm.

The upper blocks (320) of the continuously built retaining wall blocks may be located behind the main blocks (100) by the height 1/10 of the main blocks (100) than the lower blocks (310) by building inward.

When the main block (100) is coupled left and right by the coupling projections (110, 120) and the coupling grooves (130, 140), the outer wall surface portion of the retaining wall, to which the side surfaces of the main block (100) are not coupled, is formed of a surface block (250) having a flat or curved side surface, instead of the coupling projections (110, 120) and the coupling grooves (130, 140).

Geogrids (400) are inserted between layers of the continuously built retaining wall blocks and are arranged to extend towards the rear of the retaining wall, and the fixing pins (230) pass through the geogrids (400) and are fixedly arranged. The successive courses may also be formed by a row of the face blocks (250).

The vertical retaining wall modules (500) which are not built inwards are correspondingly combined and arranged at the inwards building part, namely the upper side, the lower side or the left side and the right side of the inwards building modules (600) according to the terrain;

and the vertical retaining wall module is constructed by building blocks (100, 250) in a straight line, and has a half-sheet specification of the retaining wall blocks (100, 250), and further has a linearly arranged cross building part in which adjacent blocks are stably connected without being separated from each other due to a length difference when each building is performed.

Advantageous effects

The beneficial effect of the invention is that,

according to the present invention, the retaining wall structure is coupled left and right by the left and right coupling protrusions and the coupling grooves and vertically coupled by the fixing pins, so that the retaining wall structure is prevented from being extruded out of position by impact in the horizontal direction during an earthquake, and is stably built and not easily collapsed. According to the structure of the building block main body, when the building blocks are built up and down, the building blocks can be built backwards, and are more natural and stable than vertical building;

the inward building part of the inward building part is that vertical retaining wall modules (500) which are not built inwards are correspondingly combined and arranged according to terrains on the upper side, the lower side, the left side and the right side of the inward building module (600), and retaining wall blocks can be arranged while flexibly coping with the environments with obstacles such as terrains.
