보강 일체형 숏크리트 옹벽의 구축방법{Shortcrete retaining wall construction method}Shortcrete retaining wall construction method

본 발명은, 네일, 어스앵커, 락볼트 중 어느 하나에 의한 지반보강공으로 보강된 지반 표면에 일체형 옹벽을 시공하는 방법에 관한 것으로, 더욱 상세하게는 보강된 지반에 숏크리트를 반복 시공하여 보강된 지반과 숏크리트에 의한 벽체가 일체 거동할 수 있도록 구현한 숏크리트 옹벽의 구축방법에 관한 것이다.The present invention relates to a method for constructing an integrated retaining wall on a ground surface reinforced by ground reinforcement by any one of nail, earth anchor, and rock bolt, and more particularly, ground reinforced by repeating shotcrete on reinforced ground. The present invention relates to a method for constructing a shotcrete retaining wall, which is implemented so that a wall formed by and shotcrete can be integrated.

도로, 철도 및 주택단지조성 등에서 용지의 효율적인 이용을 위해서는 대규모 지반 절취가 불가피한데, 이 경우 지반 붕괴를 막기 위해 옹벽을 적절하게 구축해야 한다.Large-scale ground cutting is inevitable for the efficient use of land in roads, railways and housing complexes. In this case, retaining walls must be properly constructed to prevent ground collapse.

도 1은 종래의 옹벽을 보여주는 도면으로, 이들 옹벽은 주로 터파기한 후 기초에서부터 옹벽 구체를 구축하고 이어 옹벽 배후를 뒷채움 하는 방식으로 시공한다. 그러한 이러한 시공방법은 전반적으로 터파기와 뒷채움 공정 진행에 따라 작업량이 많아지고 공기가 길어지는 문제가 있다. 이러한 문제를 해결하기 위해 제안된 것으로 도 2와 같은 보강 일체형 옹벽이 있다.1 is a view showing a conventional retaining wall, these retaining walls are constructed in such a way as to build a retaining wall sphere from the foundation and then backfill the retaining wall mainly after dig. Such a construction method generally has a problem that the work load increases and the air lengthens as the trench and backfill process progress. Proposed to solve this problem is a reinforced integral retaining wall as shown in FIG.

도 2는 특허 제0698758호에 따른 보강 일체형 옹벽은 네일링 공법으로 지반을 보강한 후 보강된 지반면에 일체로 철근콘크리트 벽체를 구축하는 방식으로 시공한다. 이렇게 시공된 옹벽은 보강된 지반과 철근콘크리트 벽체가 일체 거동하기 때문에 기초 없이도 구조적 안정성이 보장된다.Figure 2 is a reinforced integral retaining wall according to the patent 0698758 is constructed by reinforcing the ground by the nailing method to build a reinforced concrete wall integrally to the reinforced ground surface. The retaining wall constructed in this way ensures structural stability without foundation because the reinforced ground and reinforced concrete walls behave in one piece.

한편, 도 2에 따른 보강 일체형 옹벽에서 철근콘크리트 벽체는 도 2(b)에서와 같이 돌출된 네일 두부에 벽체철근을 걸친 후 콘크리트를 타설하는 방법으로 시공했다. 그러나 이러한 방법은 콘크리트 타설을 위해 벽체거푸집을 설치해야 하는 불편이 있었다.On the other hand, the reinforced concrete wall in the reinforcement-integrated retaining wall according to Figure 2 was constructed by placing the concrete after the wall reinforcement on the protruding nail head as shown in Figure 2 (b). However, this method was inconvenient to install wall formwork for concrete pouring.

본 발명은 상기한 종래 보강 일체형 옹벽 시공에서 벽체거푸집 설치에 관한 문제를 개선하고자 개발된 것으로서, 벽체거푸집을 설치하지 않고도 보강 일체형 옹벽을 구축할 수 방법을 제공하고자 한다.The present invention was developed to improve the problems related to the wall formwork installation in the conventional reinforcement integrated retaining wall construction, and to provide a method of constructing a reinforcement integrated retaining wall without installing the wall formwork.

상기한 기술적 과제를 해결하기 위해 본 발명은 네일, 어스앵커, 락볼트 중 어느 하나에 의한 지반보강공으로 보강된 지반 표면에 일체형 옹벽을 시공하는 방법에 관한 것으로, 더욱 상세하게는 보강된 지반에 숏크리트를 반복 시공하여 보강된 지반과 숏크리트에 의한 벽체가 일체 거동할 수 있도록 구현한 숏크리트 옹벽의 구축방법을 제공한다.In order to solve the above technical problem, the present invention relates to a method for constructing an integrated retaining wall on a ground surface reinforced by ground reinforcement by any one of nail, earth anchor, and rock bolt, and more specifically, shotcrete on reinforced ground. It provides a construction method of shotcrete retaining wall implemented so that the wall by the reinforced ground and the shotcrete by the repeated construction can be integrated.

본 발명에 따르면, 보강된 지반과 철근콘크리트 벽체가 일체 거동하는 보강 일체형 옹벽을 철망과 숏크리트의 반복 시공으로 구축하기 때문에 벽체 거푸집 설치과정을 생략할 수 있으며, 이에 따라 공사비를 절감하고 공사기간을 단축하면서 보강 일체형 옹벽을 시공할 수 있다.According to the present invention, since the reinforcement-integrated retaining wall in which the reinforced ground and the reinforced concrete wall are integrally constructed is constructed by repetitive construction of the wire mesh and the shotcrete, the wall formwork installation process can be omitted, thereby reducing the construction cost and shortening the construction period. Reinforcing integral retaining wall can be constructed.
