Description

Arched Temporary Structures {Arch Wall Shoring Structure}

The present invention relates to an arc-shaped temporary clam structure, and more particularly, to an arc-shaped temporary clam structure that firmly supports a back earth pressure acting as an excavation space with an arc-shaped clam panel.

In general, underground construction is used to construct underground structures in civil engineering or building construction, and the underground space is utilized to excavate the ground before the excavation of the ground so that the ground does not collapse due to earth pressure generated during construction. We are constructing.

The temporary soil structure is constructed in a variety of methods depending on the size of the earth pressure acting on the excavation surface, the site conditions, the type of the structure, the construction method, etc., the construction method of the temporary soil structure is a sheet pile method, RSW method, RPRW method, PSS method, SGP method, soil barrier method using two-row H-pile, CSR method, e-PHC method, and the like.

Sheet pile method is a method of forming a continuous wall by biting the joint of a board pile to form a ground by using a vibration hammer, WATER JET, etc., which is difficult to type on hard ground, and on the back of soft ground There is concern about sinking, construction is delayed when there is underground buried, deep excavation is difficult, if the section is cut, it is vulnerable to water pressure or earth pressure, there is a big noise in the type.

The RSW method is a soil wall construction method for installing a brace while excavating H-Pile by drilling or direct hitting, and forming a wall by incorporating a steel sheet bent between the H-Pile with a vibro hammer, and supporting a steel sheet. Due to earth pressure after excavation, the wall is full and the rigidity of the wall is small, so it is difficult to apply to the site where a large earth pressure is applied, and the construction precision is required, which makes it difficult to construct.

The RPRW method is a two-wall pile that is joined at a predetermined angle on the rear side and the front side of the excavation, which is connected to the frictionless hinge at the head to resist earth pressure, and the excavation of the wall caused by earth pressure after excavation. When it is considered in the longitudinal direction, the earth pressure bearing force is close to zero when it is considered in the longitudinal direction, and the entire excavation surface is pushed toward the excavation surface, and there is a decrease in construction efficiency due to interference pile insertion and spacer installation. In addition to the rather difficult interpretation, there is a problem of private land violations caused by sloped piles during urban construction.

The PSS method is a method that does not use large equipment for drilling and driving, and then press-fits after assembling the material and excavates the inside with only a small excavation equipment, so that noise and vibration do not occur. Since the construction cost is high, the installation and the excavation is made at the same time, the verticality management is important, so the work is difficult, the degree of orderability is bad, and a special prop is required, which increases the construction cost.

In addition, the PSS method has to work after crushing when exposed to the lower arm and it is difficult to stand when there are obstacles in the post.

The SGP method is a method of incorporating a guide file at equal intervals (C.T.C 1,280 or 1,300) on the plan surface of the temporary facility, and then injecting a hot rolled steel sheet suitable for the planned root position between the guide files to complete the soil wall prior to breaking the wall.

The two-column H-pile is a mudstone method that is combined with a post-heated pile that prevents shear destruction of the mud wall with the concept of heat transfer pile and an interference pile that serve as a mud wall.

The CSR method is a self-supporting mudstone method that is combined with a heat transfer pile that serves as a mud wall, and a rear heat pile that prevents shear destruction of the mud wall with the concept of an interference pile.

The e-PHC method is a method of forming an earth wall by accessing the e-PHC (high strength centrifugal pile) ready pile.

The soil barrier method using the two-row H-pile, the CSR method has a problem that the excavation depth is limited, the e-PHC method requires a precise vertical construction when excavation has a problem that the construction work is difficult, There is a problem that the construction cost is increased due to the air delay in the rock layer.

It is an object of the present invention to increase the rigidity of the wall member to reduce the number of members to be inserted into the ground, to provide an arc-shaped temporary scaffold structure to enable concrete pouring without the construction of the formwork separately.

The object of the present invention is an arcuate wall member that is arched bent in the arch, and both sides end of the arcuate panel member is fixed to the arched wall is inserted into the ground including a flat panel member covering the curved inner surface of the arched panel member It is solved by providing an arched hypothesis, including a structure.

The present invention has the effect of increasing the stability and at the same time the depth of independence by stably supporting the back earth pressure by the arching effect using an arched wall with a large rigidity.

According to the present invention, the required number of members is reduced, and the construction process is simplified, so that the construction period is shortened, so that the construction is quick and the construction cost is low.

In addition, the present invention has a form-integrated design, it is possible to pour concrete without installing a separate formwork is less construction cost, there is an effect to shorten the construction period.
