Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a slope reinforcement panel assembly,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope reinforcement panel assembly and a method of constructing the slope reinforcement panel assembly. More particularly, the present invention relates to a slope reinforcement panel assembly in which a reinforcing member provided between a panel and a slope forming an outer wall of a retaining wall can be bent and extended. And a construction method.

Generally, there are mostly cut slopes in areas where a river, a shore, or hills are cut and flattened (eg, apartment complexes) or roads are constructed.

Since the cutting slope is mainly formed by artificial cutting operation, when the cut slope is left as it is, there is a risk of the slope collapse due to continuous weathering such as air contact and storm penetration.

In other words, when the cohesion of the slope is weak and a large amount of storm is penetrated, the slope easily breaks down and causes an accident.

In order to prevent the occurrence of landslides on the cut slope, it is necessary to construct a wall that resists the soil pressure of the slope, that is, a retaining wall on the periphery of the slope to prevent the loss of the soil, It blocks in advance.

As a slope reinforcement method for slope slope, conventionally, a site-cast concrete reinforced concrete wall method has been used. In this case, excessive work work and construction cost are required to install and dismantle the form, Since the concrete retaining wall laid in the formwork had to remain in place until it was completely cured and cured, it took a long time to construct the concrete.

Recently, a retaining wall construction method using a permanent anchor has been introduced as one solution to solve the problems of the conventional concrete retaining wall construction method.

In the form of the retaining wall construction using the permanent anchor, the anchor holes are first drilled at predetermined positions on the cut slope, the anchors are inserted into the anchor holes, and then the anchors and the fixing body are fixed and cured.

The free ends of the anchors are connected to a large concrete panel or plasterboard, and the prestress is applied during installation.

Thereafter, the retaining wall is stabilized by filling the concrete panel or the plasterboard with voids between the cut slope and the soil (eg, useful soil) that can be easily obtained at the work site, and then performing the compaction work or putting shotcrete .

In the case of the retaining wall structure using the permanent anchor, the concrete panel connected to the anchor or the soil which is filled with the backing of the pressure plate is compressed so as to compress the entire cut slope, thereby preventing the cut slope from collapsing, It was a fact that we were able to reduce some of the workforce and construction costs that had been incurred.

However, in order to effectively compress the cutting slope with the soil, the retaining wall structure using the permanent anchor is used to simultaneously support the soil pressure of the filled soil and the soil pressure of the slope, that is, I could not help it.

In this case, there is a problem that the operator is somewhat difficult for the operator to carry the platen, so that there is a problem that not only the workability is lowered but also the safety of the workplace is lowered due to exposure to various safety accidents.

In addition, in the case of a retaining wall structure using permanent anchors, an anchor, which is a main reinforcing means, is previously installed at the time of installation of a retaining wall, so that the reinforcing effect is only provided when additional external force is applied. It may be difficult to implement properly.
