Description

Frame Structure for Underground Structure and Method of Constructing Underground Structure Using the Same}

The present invention relates to a frame structure for underground structures and a method for constructing underground structures, and more particularly, to an underground structure having a concrete structure that is poured into the frame structure to support a frame structure forming a skeleton of the underground structure and a load applied to the frame structure. It is about a structure.

Underground structures are being built underground for the movement of water and sewage, the laying of communication and power cables, and the passage of people.

When constructing these underground structures, non-adhesive methods are used to bury the ground without digging the ground.

On the other hand, some underground structures have a frame structure that forms the skeleton of the underground structure, and a concrete structure that is poured on the frame structure to support the load applied to the frame structure.

10 is an exploded perspective view of a conventional frame structure for underground structures.

The conventional frame structure for underground structures, as shown in Figure 10, has a tubular pour space portion 120, and the movement path pipe portion 111 provided inside the pour space portion 120.

The pouring space portion 120 is formed to have a circular cross section, and the gap portion 121 is formed on the inner surface of the protrusion.

The movement path pipe part 111 is formed to have a circular cross section and is installed in the pouring space 120 to be supported by the gap portion 121.

A method of constructing an underground structure using a conventional frame structure for underground structures having such a configuration will be described below with reference to FIGS. 11 and 12.

Frame Structure Production Stage for Underground Structure

In the state in which the pouring space 120 and the movement path pipe portion 111 is separated from the conventional frame structure 110 for underground structure to produce and transport to the site to install the underground structure (see Figure 10).

Pour space  Buried stage

The pouring space 120 is buried underground in a non-adhesive manner. The pouring space 120 may bury a plurality of continuously by adapting to the length of the movement path to be formed underground (see Fig. 11). The pouring space 120 is sequentially coupled one by one to the pouring space 120 that is first pressed in the order of being pressed.

The embedding of the pouring space 120 may be carried out by a press-fit method using a propulsion equipment 201, a reaction force wall 202, a lead pipe 203, etc., including a hydraulic jack as is conventionally known.

Moving path pipe  install

After the embedding of the pouring space 120 is completed, the moving path tube 111 is installed inside the pouring space 120 so as to be supported by the gap 121 (see FIG. 12).

Concrete Structure Formation Step

The concrete structure 131 is formed by pouring concrete in the space between the movement path pipe part 111 and the pouring space 120 (see FIG. 12). Here, the concrete structure 131 is formed by sealing the open areas formed at both ends between the movement path pipe part 111 and the pouring space part 120, and then moving the concrete through the injection holes formed in the pouring space part 120. It can be carried out by a method of filling between the 111 and the pouring space 120.

After building the underground structure using the conventional frame structure for underground structures 110, it is possible to install additional equipment such as a sump.

By the way, according to the conventional frame structure for underground structures, underground laying is complicated (moving path pipe portion and pour space must be buried separately), the concrete structure 131 must be poured integrally, the structure of the moving path pipe portion 111 Is complicated (must form a gap), there is a problem. When the concrete structure 131 is integrally placed, a secondary problem occurs that the curing period is long and a region in which concrete is not filled is generated.

It is achieved by the frame structure for the underground structure.

Wherein the movement path pipe portion is formed to have a rectangular cross section so as to reduce the vertical earth pressure applied to the left pouring space portion and the right pouring space portion; Preferably, the left pouring space portion and the right pouring space portion are each formed in a convex curved shape.

And a lower left pour extending from the left pour space portion so as to protrude beyond the bottom of the moving path pipe portion and form a left lower pour space between the left pour space portion so as to prevent corrosion of the bottom surface of the movement route pipe portion. It is preferable to further include a lower right placing space portion which extends from the right placing space portion so as to protrude beyond the bottom of the space portion and the movement path tube portion and the right placing space is formed between the right placing space portion.

On the other hand, the above object is in the underground structure construction method for constructing the underground structure underground to provide a movement route underground in accordance with another field of the present invention, fabricating the frame structure according to any one of claims 1 and 2. A frame structure fabrication step; An upper concrete structure forming step of forming concrete on the upper surface of the upper left casting space part, the upper right pouring space part and the moving path pipe part to form an upper concrete structure; An underground embedding step of embedding the frame structure in which the upper concrete structure is formed in the basement in a non-adhesive manner; A left concrete structure forming step of pouring concrete into the left pouring space to form a left concrete structure; It is achieved by the underground structure building method comprising the step of forming a concrete to form a concrete structure by pouring concrete to the right casting space.

Therefore, according to the present invention, the pouring space is formed on the left side, the right side, and the upper surface of the movement route tube, respectively, while the upper surface of the movement route tube is buried underground in the left side and the right side of the movement route tube. By allowing concrete structures to be formed, underground laying is simple (moving path pipe and pouring space can be buried at the same time), and concrete structures (upper concrete structures, left concrete structures and right concrete structures) can be divided and poured. The structure of the movement route tube becomes simple.
