Description

Prefabricated revet construction and prefabricated revet construction method using Technical

In the present invention, in the construction of the retaining wall in the cut portion, the panel formed of precast concrete (PC) forms a smooth or reversed retaining wall. (SOIL NAIL) is to be fixed to the rock or soil after being bonded to the tension and support fixed, the outer circumferential surface of the retaining wall (PC) panel is a head cap is formed to easily check or reinforce the anchored coupled anchor In order to improve the workability according to the repair, the upper and lower ends of the retaining wall (PC) panel, which are assembled in a top and bottom stack type, have a connecting or fastening thread screwed inside a separate c-shaped steel to promote a stronger binding of the retaining wall. Cut to be formed so as to improve the integrity of the structure while ensuring the standing (standing) rigidity of the retaining wall structure It relates to allogamy and reverse allogamy retaining wall structure.

In this way, the present invention is buried with c-shaped steel inside the retaining wall (PC) panel corresponding to the earth anchor (EARTH ANCHOR) or the SOIL NAIL to greatly improve the resistance of the tensile strength as well as irregular drilling angle The base plate with an adjustable external thread is used to securely and easily adjust the tension force even for an inexperienced person. The retaining wall (PC) panel has a large assembly (connection) and watertightness (or drainage) between blocks. It is improved, and the simple construction is characterized in that the construction period is significantly shortened.

In addition, the present invention is formed in the anchor body to support the retaining wall (PC) panel while being embedded in the rock or soil to the back surface excavated during construction of the retaining wall is formed, the anchor body is largely composed of the tension portion and the end head In addition, the end head is formed so that the support joint and the support holder connected from the steel wire is compact and simple structure, while the tension is secured by the restraining disc and the toothed support legs extended to the soft ground after entry, so as to be settled. By being in close contact with the same rock wall, the operator is easy and easy to construct the construction of the anchor body, while the buried anchorability is improved, the construction safety is significantly improved.

Generally, a wall that resists earth pressure so that soil or rock does not collapse is called a 'retaining wall', and the retaining wall is fixed by using anchors or rock bolts and nails.

Reinforced concrete retaining wall for conventional civil engineering is because the bending moment acting on the retaining wall by the backing soil is approximately increased in proportion to the square of the retaining wall height, inevitably to secure the rigidity against the bending moment The cross-sectional area and the amount of reinforcing bars in the wall increase greatly with the height of the retaining wall.

Therefore, a large amount of concrete and expensive reinforcing bar was a factor of increasing the cost of construction, there are many cases of defects caused by the difficulty of construction, continuous maintenance is required, there is a risk of retaining wall collapse due to poor construction.

In addition, in order to prevent the collapse of the slope, the conduction moment should be reduced to the minimum and the resistance moment should be increased to the maximum. Therefore, the slope of the slope should be less than the angle of repose as well as rainfall, earthquake, etc., because safety measures are required accordingly. Safe slopes should be made against sudden geniuses, and if the height of the cross section is large, the slope should be set slower as you go down.

At this time, the most problem in the safety of the slope is about drainage, and osmosis due to groundwater, rainwater or snowfall is important, and if water is not well drained from the mower or the heaping, In addition to increasing the unit weight of the soil and increasing the conduction moment, it is formed to reduce the resistance moment by weakening the soil near the fracture surface.

In addition, even if water does not penetrate into the soil, it is accumulated on the back or top surface of the slope, thereby increasing the conduction moment due to the water pressure, thereby causing a problem of destruction.

However, the conventional retaining wall construction method and the constructed retaining wall are installed after the foundation concrete is laid on the ground on which the retaining wall is to be installed, and after the fixing pin is inserted into the foundation foundation to be installed, it is loaded and fixed in the hole formed at the bottom of the panel. There is a problem that the construction period takes a long time because the secondary concrete is poured into the back of the curing.

In addition, if the pin is inserted deeper than the proper value, it is difficult to modify, so it is necessary to remove the foundation and re-install the concrete, which incurs an additional part of the construction cost, as well as parallel to the curved terrain. If there is a need to install a gap between the panel and the panel is a problem that the gravel and soft soil is discharged into the gap between the panel and the panel.

In addition, since the drain hole is horizontally drilled in the middle part of the panel, the water discharged by the earth pressure is not discharged to the outside quickly through the drain hole but stays inside to increase the earth pressure, thereby increasing the pressure on the retaining wall. In addition, the water discharged in front of the installed retaining wall flows into the filling site of the other retaining wall, and there is a danger that the retaining wall may collapse due to the increase of water pressure and earth pressure in the final retaining wall.

The present invention is to solve the above-mentioned problems, the technical gist of the panel formed of precast concrete (PC) to form a forward or reverse type retaining wall, the retaining wall panel is an anchor (EARTH ANCHOR) ) Or soil nail (SOIL NAIL) is to be fixed to the rock or earth and sand after being bonded to the fixed and support, the outer circumferential surface of the retaining wall (PC) panel, the head cap so as to easily check or reinforce the anchored coupled body It is formed to improve the workability according to the maintenance, as well as the upper and lower ends of the retaining wall (PC) panel is assembled in a vertical stacking structure, the connecting or fastening muscles to separate the connection or fastening muscles to promote a more solid binding of the retaining wall It is designed to be screwed inside to improve the structural integrity while ensuring the standing (stiffness) rigidity of the retaining wall structure.
