In general, a retaining wall refers to a wall made so that the slopes formed by cutting the soil or building up soil do not collapse under the pressure of the soil. That is, it refers to a structure made for the purpose of preventing the collapse of the soil behind, and it is a structure that maintains stability with the retaining force of the retaining wall against the soil pressure behind.

This type of retaining wall is made of plain concrete, and it is made of gravity retaining wall and reinforced concrete, which is stabilized by its own weight. Rear wall retaining wall reinforced with subwalls and front wall retaining wall reinforced with subwalls at regular intervals in front of the cantilever retaining wall.

Looking at the construction procedure of the cantilever retaining wall most widely used in the conventional retaining wall described above, the trench and the foundation surface is arranged in the place to install the retaining wall. When the foundation surface is arranged, the foundation concrete is poured on the foundation surface. At this time, if the foundation concrete lacks bearing strength, reinforcement by installing more ground improvement or pile. After the foundation concrete is poured, reinforce the floor reinforcement and pour the concrete. The reinforcing wall reinforcement is placed on the poured concrete and the concrete is poured to complete the cantilever retaining wall.

This is a plan view of the eco-friendly retaining wall shown in accordance with the construction method. Hereinafter, a construction method of an environmentally friendly retaining wall provided with a water collecting port 6 using a circular PHC pile according to the present invention according to the flowchart shown in FIG. 3.

As shown in Figure 3 and 5, the PHC pile buried step (S100) is formed a plurality of PHC spaced apart a predetermined distance in the longitudinal direction of the PHC pile 2 along the ground (100) to form the environmentally friendly retaining wall (1) A plurality of circular PHC piles 2 integrally formed with a circular band-shaped steel band 21 having a predetermined width surrounding the pile 2 are embedded at a predetermined distance. At this time, the method of embedding the PHC pile (2) in the ground (100) is preferably used in the embedding method, the embedding method may be used in the middle digging method, SIP method, SDP method, PRD method and the like.

As shown in Figure 3 and Figure 6, the PHC pile one surface excavation step (S110) excavates one surface is formed the outer surface of the environmentally friendly retaining wall (1) of both sides of the embedded PHC pile (2). As such, since the excavation is performed in the state in which the PHC pile 2 is embedded, the stability of the work can be ensured. At this time, the excavation surface 110 is preferably to form an excavation surface 110 on the basis of the center of the circle of the PHC pile (2). This is for installation of the water collecting port 6 to be described later.

As shown in Figure 3 and 7, the stopper welding step (S120) is spaced apart to one side of the excavated PHC pile (2) of one side of the plate-shaped bar formed in parallel with the longitudinal direction of the outer surface of the PHC pile (2) A plurality of plate-shaped stoppers 3 having a predetermined length for connecting and fixing the plate 22 and the steel band 21 to each other are fixedly installed. The stopper 3 forms the same number of steel bands as the environmentally friendly retaining wall 1. At this time, the coupling end of the plate and the stopper is fixed to the stopper to be perpendicular to one side of the plate so that the "T" shape. This fixed coupling method may use a conventional welding. Along with the stopper 3, the plate-shaped auxiliary plate 23 parallel to the plate 22 is fixedly installed. The method of mounting the auxiliary plate 23 on the stopper 3 is the same as the installation method of the plate 22. In particular, since the auxiliary plate 23 is installed, both side ends of the panel 5 having the catchment 6 to be described below are integrally fixed between the plate and the auxiliary plate.

3 and 8, the panel fitting installation step (S130) provided with the catchment is formed in the form of the "U" pipeline of a predetermined length between each stopper (3), the bottom of the "U" pipeline A plurality of catching holes 611 are formed on the surface 61, and end openings 63 of both end walls 62 having a “U” conduit shape are formed relatively wider than the bottom surface 61.

The re-excavation step (S200) is performed at least once according to the height of the eco-friendly retaining wall (1). That is, as an example, if the height of the eco-friendly retaining wall 1 is three times or more with respect to the height of the panel 4 provided with the water collecting port, the re-excavation step S200 is repeated twice, and the height of the eco-friendly retaining wall 1 is 5 times. If more than twice is to repeat the re-excavation step (S200) four times. In this case, when two or more panels having water catches for forming an eco-friendly retaining wall are stacked in the re-excavation step (S200), an overlapping surface may be formed between upper and lower portions of the panel provided with stacked catches and may be overlapped between overlapping surfaces. The expansion index material 9 can be further applied.

As shown in FIGS. 3 and 9, in the sand layer forming step S140, sand is embedded in the excavation surface 110 formed on the outer side of the catchment 6 to form the sand layer 10. In particular, the formation of the sand layer 10 outside the catch port 6 is to prevent the earth pressure of the ground (100) increases when the components of the ground (100) is not easy to drain water due to the various components. That is, the sand is embedded in the space between the excavation surface 110 and the bottom of the bottom surface 61 of the water collecting port 6 to increase drainage performance. In addition, the sand layer 10 is preferably provided with a space between the excavated PHC pile (2), the panel 4 provided with the water collecting port and both side walls 62 of the water collecting hole (6).

At this time, the exterior material 5 is coupled to the anchor bolt 51 and the nut 52 in the present embodiment, but the use of an adhesive will be possible. Here, the exterior material 5 may use any one of ore and acrylic plates such as plate-like artificial wood or wood, plate-shaped granite and marble or artificial granite and artificial marble.

Cap concrete finish step (S160) is described with reference to Figures 1 and 2 and 11 described above, the cap concrete finish step (S160) is the PHC pile (2) upper portion of the eco-friendly retaining wall (1), the water collecting port (6) is completed Finish with cap concrete (7). This is because the PHC pile (2) to form a hollow in the longitudinal direction is to use the cap concrete (7) to finish it.

3 and 11, between the stopper fixing installation step (S120) and the panel fitting installation step (S130), the auxiliary guide piece 31 fixed installation step (S121) and the guide bar 32 fixed installation step It may further include (S122). At this time, the auxiliary guide piece 31 fixed installation step (S121) is fixed to the plate-shaped auxiliary guide piece 31 formed at right angles to one surface of the upper end of each plate (22). In addition, the guide bar (32) fixed installation step (S122) is the guide bar 32, the shape of the cross-section on top of each of the auxiliary guide piece 31 of the "c" port steel, "L" section steel and "H" port steel 32 ) Can be fixed. This is to prevent the change of the interval of the plate 22 fixed by the stopper to the PHC pile (2) for easy installation of the panel (4) provided with the water collecting port (6). The auxiliary guide piece 31 fixed installation step (S121) and the guide bar 32 fixed installation step (S122) after the sand layer forming step (S140) after the auxiliary guide piece fixed installation step (S121) and guide bar fixed installation step (S122) It is preferable to remove in step (S141) to remove the auxiliary guide piece 31 and the guide member 32 installed in the). In other words, the eco-friendly retaining wall 1 is removed before completion.
