Description

Block for backfilling and method backfilling by that}

The present invention relates to a banding groove filling block and a groove filling method, and more particularly, is attached and fixed with a magnetic force between the wall and the strip, so that the gap between the wall and the strip simply fill the gap between the groove and support. A filling block and a groove filling method using the groove filling block.

In general, to construct underground structures in civil engineering or building construction, the underground space is utilized by excavating the ground, and the excavation surface of the ground after the excavation of the ground is used to prevent the ground from collapsing by soil pressure generated during construction work. We are constructing.

The retaining wall is constructed by various methods according to the size of the earth pressure acting on the excavation surface, site conditions, the type of the structure to be constructed, the construction method, and the like, as the construction method of the retaining wall, the H pile earth wall method, CIP (Cast-In). -Placed concrete pile method, underground slurry wall method, sheet pile method, etc.

Since the retaining wall is constructed perpendicular to the excavation surface to support the ground, there is a risk of collapse due to earth pressure when the excavated depth is greater than a certain depth. Therefore, during construction of the underground structure, a temporary structure for temporarily supporting the retaining wall is installed.

The temporary structure is not required to be installed if the excavation depth is not deep, but in recent years when constructing underground structures, most of the ground is excavated to a depth that requires the installation of the temporary structure, and in order to secure the safety of the ground excavation site, The situation is to install a temporary structure to temporarily support the wall.

As shown in FIG. 1, the temporary structure supports a strip 3 installed horizontally along the wall surface of the earth retaining wall 2 constructed to support the excavation surface of the ground 1 and the strip 3. It includes a brace (4).

The strip 3 is mainly using an H beam member 3a, and the brace 4 is installed across the earth wall 2 so that both ends support the strip 3 respectively.

In addition, the H-beam member 3a, that is, the strip 3 is in close contact with and constructed with the earthenware wall 2 to support the earth pressure. It is a situation that is being constructed in the state where the gap is generated.

Therefore, when constructing a temporary structure, the filling of the gap between the strip wall (2) and the earth wall (2) to fill the gap between the wall wall (2) and the strip (3) is made, the home filling used for the home filling The block 5 is usually a steel or wood block having a relatively high load capacity against the compressive force is used.

That is, the groove filling block 5 is provided with a plurality of intervals between the strip 3 and the retaining wall (2) to fill the gap between the strip 3 and the retaining wall (2) And by supporting the resistance to earth pressure generated in the reinforcement (4) to the retaining wall (2) to support the strip (3) and the reinforcement (4) to effectively support the retaining wall (2).

On the other hand, the existing groove filling method is different depending on the type of the wall wall, but processing the wall wall (2) in parallel with the strip (3), by cutting and cutting the steel or wood block that is the groove block (5) to fit the gap It is common to fill the space between the retaining wall 2 and the strip 3.

In addition, in the case of the grooved block 5 is made of steel, it is fixedly installed by welding to the retaining wall 2 and the strip 3 respectively, and in the case of wood, a type is formed between the retaining wall and the strip using a hammer or a hammer.入) is common.

For reference, there is also a home filling method for installing a small formwork between the retaining wall (2) and the strip (3) and placing mortar, but this is a work that must be installed, mixed and transported after the formwork is installed and mixed with the mortar. It takes a lot of time and is being used on a limited basis.

The groove filling method is classified as follows according to the type of the wall wall.

First, as shown in Figure 2a, the CIP wall (2a) constructed by the CIP method is because the concrete wall with the H-beam pile (2d) is built at a predetermined interval, the flange plane of the H-beam pile (2d) Using the groove filling block 5 is installed, the groove filling block 5 is installed by welding in case of steel, and in the case of wood to install by type.

In addition, as shown in Figure 2b, the underground continuous wall (2b) constructed by the underground continuous wall method is to insert the groove filling block (5) at regular intervals at intervals along the wall surface to fill the groove.

In addition, as shown in Fig. 2c, the sheet pile wall 2c manufactured by the sheet pile method has a continuous sheet pile forming a wall surface, so that the groove filling block 5 is simply inserted into the flat portion of the sheet pile. Will be performed.

As described above, in the case of the groove filling block 5 applied to the CIP method, the underground continuous wall method, the sheet pile method and the like as described above, steel or wood is mainly used, but the compressive strength of the wood is low, Due to the problem of being deformed by moisture or heat, many steel materials have recently been applied.

However, in the case of the steel-filled groove block, there is a hassle to cut and process the width and thickness to fit the gap between the earth wall (2) and the strip (3) in the construction site, and also this wall wall (2) Since the welding and fixing to each of the strip length 3, the installation and dismantling work was very difficult.

In particular, since the installation operation of the grooved block 5 is made in a very narrow space, as shown in FIG. 3, after cutting and processing the diameter of the lower part rather than the diameter of the upper part, the welding is performed only on the upper side. In many cases, there is a big problem of safety accidents due to the occurrence of band dents due to stress transfer imbalance in the upper and lower parts.

The present invention has been made in view of the above problems, by providing a magnetic groove filling block of various sizes having a magnetic, so that it can be easily installed between the wall and the strip, it is very excellent in construction and safety It is an object of the present invention to provide a groove filling block and a groove filling method.

In order to achieve the above object, the belt-filling groove-filling block according to the present invention includes an earthquake wall constructed on an excavation surface of the ground; A bandage installed horizontally along the wall surface of the retaining wall to support the retaining wall; It is characterized in that it comprises a magnetic groove filling block which is interposed on the wall and the strip and attached to the wall and strip, respectively, by magnetic force.

In this case, it is preferable that the magnetic groove filling block is formed to have the same upper diameter and lower diameter.

In addition, the magnetic groove filling block is preferably provided in sizes having various widths and thicknesses according to the distance between the wall and the strip.

On the other hand, the groove filling method using the band-filled groove filling block according to the present invention comprises the steps of: (a) constructing an earthen wall on the excavated surface of the ground; (b) installing a strip for supporting the retaining wall along the wall of the retaining wall; (c) inserting a magnetic groove filling block having magnetic force between the retaining wall and the strip, thereby allowing the magnetic groove filling block to be attached and fixed to the retaining wall and the strip, respectively.

As described above, according to the banding groove filling block and the groove filling method, since the groove filling block interposed on the wall and the strip has magnetic force, it is easily attached and fixed to the wall and the strip, respectively. The welding process is excluded, and the workability is greatly improved.

In particular, in the prior art, in order to weld the grooved block, the diameter of the lower part is smaller than the diameter of the upper part, and it is common to fix only the upper part. Although the groove filling block according to the present invention has a magnetic force, the welding process is excluded, and the upper and lower diameters are formed to be the same, so that both surfaces are fixed and fixed to the wall and the strip, respectively, and the structural rigidity is also Improved effects are provided.
