After (S101), the concrete 73 is poured to remove the formwork 71 when the concrete is cured (S102). Thereby, as shown in FIG. 6B, the hollow hole 47 formed in the fixing pipe 41 of the buried fixing table 33 is exposed to the outside. Thereafter, as illustrated in FIG. 6C, after the silicon 75 is injected into the exposed hollow hole 47 (S103), the handle scaffold 51 is fitted into the handle scaffold 51 as illustrated in FIG. 4. ) Is fixed to the landfill. As a result, the groove 53 formed in the handle scaffold 51 is fastened to the grip ring 43 so that the handle scaffold 51 is fixed to the buried stand 33, and the handle scaffold 51 is made of silicon 75. ) Is not shaken in the buried fixing (33).

이와같이 시공방법에 의해 매설사다리(21)는 예컨대 도 7에 도시된 것과 같은 맨홀 등과 같은 지하 구조물 또는 지상 구조물의 벽 등에 설치될 수 있다.In this manner, the buried ladder 21 may be installed in a wall of an underground structure or a ground structure such as a manhole as illustrated in FIG. 7.

위에서 설명한 바와같이 본 발명에 따른 매설사다리 및 이의 시공방법은 설치가 간편하고, 거푸집에 구멍을 뚫지 않고도 시공할 수 있어 거푸집의 낭비를 막을 수 있는 효과가 있다.As described above, the buried ladder according to the present invention and the construction method thereof are easy to install and can be installed without drilling holes in the formwork, thereby preventing the waste of formwork.
