Description

Retaining wall and its manufacturing method

The present invention relates to a retaining wall used in the ground work for the installation of road bridges, and more specifically, to the structure of the road bridge that can facilitate the installation of the retaining wall with the stability of the soil structure where the retaining wall is installed. It is about a retaining wall.

Recently, with the development of the industry, the movement of population and goods is increasing rapidly. To solve this problem, construction for social overhead capital facilities such as roads and railways is actively underway. In particular, when a bridge construction is performed on a slope, it is necessary to install a retaining wall to prevent the soil in the portion where the pillars of the bridge are embedded at the end of the bridge when installing the bridge.

1 is a cross-sectional view showing a cross section of a conventional retaining wall.

)에 의하여 전방으로 밀림으로써 전도되는 것을 방지하기 위하여 베이스부(210)의 하부에 돌출 연장된 활동방지벽(Shear key; 230)으로 구성된다.As shown in FIG. 1, the conventional retaining wall 200 is applied to a base portion 210 positioned at the bottom, a wall portion 220 protruding upwardly of the base portion 210, and a wall portion 220. Earth pressure

In order to prevent the fall by pushing forward by the () is composed of an active barrier 230 (Shear key 230) protruding from the lower portion of the base portion 210.

The installation process of the conventional retaining wall 200 will be described with reference to FIGS. 2A to 2D.

2A to 2D are flowcharts illustrating a process of installing a conventional retaining wall.

)에 비례하여 충분한 여유 공간을 가진 폭(

)으로 경사지게 형성된 활동방지벽용 홈(240)으로 이루어진다.As shown in FIG. 2A, the installation of the conventional retaining wall is performed by digging a slope of a place where the base portion 210, the wall portion 220, and the activity preventing wall 230 are located. At this time, the trench at the location where the activity blocking wall 230 is located has a depth of the activity blocking wall 230 in order to secure a formwork space for the installation of the activity blocking wall 230.

Width with enough free space relative to

It consists of an activity preventing wall groove 240 formed to be inclined.

Thereafter, as shown in Figure 2b, after forming the formwork for the production of the activity blocking wall 230 in the activity blocking wall groove 240 to produce the activity blocking wall 230.

Thereafter, as shown in Figure 2c, after the activity blocking wall 230 is formed to bury the activity blocking wall groove 240. At this time, the buried portion 250 is the soil buried in the activity preventing wall groove 240 is a narrow space for the installation of the reinforced concrete structure of the activity blocking wall 230, it is difficult to compact or efficient work.

Thereafter, as shown in FIG. 2D, the base portion 210 and the wall portion 220 are manufactured using formwork and the like, and the rear space of the wall portion 220 is buried.

However, in the case of the conventional retaining wall 200, the soil of the buried portion 250 in which the soil is buried in the activity preventing wall groove 240 is relatively weak compared to the non-buried portion 260 of the non-embedded soil structure, thereby preventing activity. There is a problem that the active displacement of the wall 230 becomes large.

)에 의하여 전방으로 밀리거나 베이스부(210)와 벽체부(230) 사이의 접합부인 작용점(231)을 기준으로 토압(

)에 의한 모멘트(

)가 발생하여 옹벽(200)이 변위를 일으켜 교량이 불안전하게 되는 문제점이 있다.As such, due to the weak soil structure of the buried portion 250, the wall portion 220 is the earth pressure (

By the forward force or by the earth pressure (230) on the basis of the action point 231 which is the junction between the base portion 210 and the wall portion 230

) Of the moment

), There is a problem that the bridge is unstable due to the displacement of the retaining wall 200.

In addition, in the case of the conventional retaining wall 200, the work process is complicated because the manufacturing of the reinforced concrete structure is required in the space of the narrowing barrier wall groove in the manufacturing process of the barrier wall.

It is therefore an object of the present invention to provide a retaining wall that can minimize the active displacement of the retaining wall of the retaining wall.

It is another object of the present invention to provide a retaining wall capable of suppressing the occurrence of a rolling phenomenon and a moment due to earth pressure.

It is still another object of the present invention to provide a retaining wall having an activity preventing wall which can be improved in workability by manufacturing in a simple process.

According to the present invention, a plurality of activity preventing walls for press-fitting perpendicular to the ground, a binding portion for binding the plurality of activity blocking walls to each other, a base portion formed to cover the activity preventing wall and the binding portion protruding on the ground, and the base A retaining wall is provided, consisting of a wall portion extending vertically on the portion.
