The present invention relates to a concrete formed wall formwork or mold of the structure excavated underground, more specifically, to the arched ceiling surface while slidingly sliding the forming frame with respect to the entire wall surface of the excavated capsule or cave-type underground structure Uncured concrete pouring works for the entire walls of underground structures without the use of additional formwork for the construction of the encapsulated or cave-type underground structures of the stable work structure, which drastically improved workability and stability while reducing construction time. It relates to a concrete mold.

As is well known, the slip form method is also called a sliding form, which is a formwork method, in order to construct a horizontal or vertically repeated structure into a uniform shape without construction joints. A method of constructing a structure by pouring concrete while continuously moving formwork. It is fixed along the inner side of the underground structure to protect and stabilize the base of the underground structure such as a vertical tunnel or a reactor vessel of a nuclear power plant. The concrete wall of thickness is constructed without construction joint.

This slim form method can be used without construction joints, continuous construction is possible, construction time can be shortened and construction cost can be reduced, and automatic measurement and control system can quickly respond to any situation that may occur during construction to produce high quality concrete structures. The advantage is that it can be constructed. However, when construction starts, work must be done continuously until completion, and thus, a plan for carrying out necessary personnel or materials is required. Therefore, design changes are difficult during construction. Therefore, preparation work must be thoroughly performed.

In particular, the conventional slip foam apparatus (forming mold) applied to such a slip foam method is usually cast on uncured concrete through the slip foam apparatus to the bottom surface and vertical wall surface of the underground structure, and then the arched cloth For the facade, additional work was needed to install the uncured concrete by installing a separate formwork without applying the slip foam device, which would increase the construction time because the uncured concrete pouring work of underground structures was not carried out in a single continuous process. Inevitably, when placing concrete in underground structures, workability and economics as well as workers' stability are declining.

Therefore, the present invention was developed to structurally solve all the problems that the slipform apparatus has not solved as described above, and step by step while sliding the molding frame by section in the excavated capsule-type or cave-type underground structure By enabling concrete pouring of concrete walls of single-walled or multi-porous walled underground structures, construction time for the formation of capsule- or cave-type underground structures can be greatly reduced, while also improving workability and economy.

In addition, the hanger deck is connected to the supply hopper and the pour chute installed through the horizontal support of the arch deck so that the uncured concrete that forms the underground structure wall can be poured through the pour chute. In addition, the arch deck is constructed by connecting the casting chute from the concrete pump car to the lifting winch which is installed and operated by anchor bolt fixed to the center bottom so that the unhardened concrete can be poured through the concrete pump car to the entire wall of the underground structure. Build relationships.

In addition, the arch deck is provided with a plurality of compactors (vibrators) on the inclined support so that the unhardened concrete poured into the arched ceiling surface of the underground structure can be evenly distributed by a certain vibration. In addition, the hanger deck is characterized in that the spraying nozzle is installed so that the ground water from the water tank can be sprayed while the unhardened concrete is poured into the underground structure. Furthermore, the multipurpose workbench is differentiated from the existing slip foam devices through a configuration in which the end portion of the underground structure protrudes slightly higher so that the falling groundwater does not overflow into the water tank through the transfer pipe.

In the following, the uncured concrete is poured without the use of a separate formwork for the arched ceiling while slidingly moving the molding frame with respect to the entire wall of the encapsulated or cave-type underground structure (90a) (90) of the excavated single wall or perforated wall. With reference to the accompanying drawings of the preferred embodiment of the present invention the specific configuration and operation of the operation that can be carried out will be described in detail.
