Description

A APPARATUS FOR APPROACH CONSTRUCTION OF LAY TYPE RETAINING WALL}

The present invention relates to a proximity construction device of a laminated retaining wall on a slope, and in particular, a means for firmly supporting a retaining wall member at a near distance on a slope requiring a retaining wall (cutting section, temporary retaining wall, reinforcement of an old retaining wall, etc.) It is an object to make it possible to construct a laminated retaining wall in close proximity to the slope.

In the conventional method of constructing a laminated retaining wall constructed using retaining wall members such as retaining wall blocks or retaining wall panels to protect the incision section, in the case of retaining wall stacking, reinforcing materials such as mats and geogrids are laminated. The retaining wall blocks are squeezed to the rear of the retaining wall blocks at appropriate intervals, and then extended to the rear. In the case of panel stacking, the support band or ladder type reinforcement is hanged on the hook provided on the back side, and it is extended to the rear, or the end is fixed with a pile, and the back filling material is filled on the retaining wall panel. It was constructed to support the non-flowing.

The construction state of the laminated retaining wall was such that the backfill space was wide enough to extend the reinforcement supporting the retaining wall member, and construction was possible only when the earth pressure was increased. Therefore, when the construction conditions were weak and inevitable to install the retaining wall near the slope, the reinforced concrete retaining wall was laid by formwork.

However, such a concrete retaining wall may collapse due to the earth pressure of the backfill material and the weighting pressure of the infiltrating water so that there are various problems in the construction, in which the earth anchors must be embedded in the concrete retaining wall at regular intervals, that is, long curing. There were problems such as period, complicated work process, much labor and expenses.

In this paper, in order to solve the above-mentioned problems, the retaining wall members are stacked in close proximity with the retaining wall requiring the retaining wall, and the retaining wall is installed close to the slope, and the retaining wall members are bound to each other by the retaining wall member. And a band hook bar at the end of the earth anchor fixed to the slope so as to pull the between the band hook bar and the retaining wall member binding bar to the retaining wall member support band to support the retaining wall member in a tensioned state. It is possible to construct a solid retaining wall in close proximity.

The structure of this paper is explained in detail as follows.

An earth retaining wall member binding bar 10 for fastening the retaining wall members 100 laterally by hanging the hook portion 101 provided in the retaining wall member 100, and an earth to which the fastening means 30 is provided at a front end. Supporting the retaining wall member 100 by pulling between the anchor 20, the band hook bar 40 to be fitted to the fastening means 30, and the band hook bar 40 and the retaining wall member binding bar 10. It is composed of a retaining wall member support band (50).

In this implementation, the binding means 30 between the earth anchor 20 and the band hanger bar 40 has a hook at the tip of the earth anchor 20, as shown in FIG. Welding so that the hook does not open, or screwing the T-shaped end pipe to the end of the earth anchor 20 as shown in Figure 4b and hook the band hanger bar 40 to it, or the end of the earth anchor 20 as shown in Figure 4c Penetration through the band hanger bar 40, the nut is filled in the front end and bound. The hook portion 101 of the retaining wall member 100 performs the hook portion 101 in the shape of a groove as shown in FIG. 5A when the object is a block, and in the case of a plate body, the hook portion 101 as in the example of FIG. 5B. ) Is carried out in a ring. The retaining wall member binding bar 10 and the band hanger bar 40 use steel pipes or steel bars.

The fixing of the retaining wall member support band 50 is a band fixing clamp that is opened to two sides in a state in which the support band 50 is tensioned by pulling the support band 50 to the retaining wall member binding bar 10 or the band hanger bar 40 as illustrated in FIG. 1. (60) can be filled and fixed.

The retaining wall construction method using this invention device as described above is as follows. The retaining wall members 100 are stacked in the vicinity of the slope requiring the retaining wall installation, but the retaining wall member binding bars 10 are hung on the hook portion 101 on the upper surface of the retaining wall member 100 at a predetermined height so that the retaining wall members 100 are horizontal. To bond with one another. On the slope immediately after the retaining wall member binding bar 10, the earth anchor 20 is fixedly installed, and the band hook bar 40 is fitted to the hook 30 provided at the tip. After the retaining wall member binding bar 10 and the band hanger bar 40 are pulled and fixed by the retaining wall member support band 50 to tension the clamping clamp 60, the backfill material 200 is formed in the space between the retaining wall member and the slope. Fill the retaining wall.

This design device used as described above is because the retaining wall member 100 of the same layer to be laminated is held by the retaining wall member binding bar 10 to bind the retaining wall member support band 50 to pull toward the slope. As the unit load of the retaining wall members increases, the supporting force becomes good, and in particular, the retaining wall member support band 50 supports a plurality of retaining wall members firmly on the slope and at a short distance so that the retaining wall can be constructed even in a place where the retaining wall construction conditions are narrow. There is an effect, and the flow of the retaining wall member is suppressed and the retaining wall is firm.
