The present invention relates to a structure of the earth plate for a construction engineer using a rubber tube, and more particularly, the width of the earth plate is increased by the air injected into the inner side of the earth plate to block the groundwater leaking out from the sidewall of the burrowed underground space. It is intended to provide a construction plate structure for construction engineers using an improved rubber tube to increase the strength of the earth plate and to prevent warpage by making the unit assembly composed of the variable wall to be variable, so that the production cost is low.

In general, the earth plate is a structure that supports the earth pressure or water pressure of the underground earthwork in the construction, construction work, which is used as a permanent structure, temporarily used as a temporary structure.

In other words, the use of land in our country is mainly concentrated in large cities, and due to the lack of available land, high-rise and high-density urban areas are accelerating. Due to the inevitable construction of the building, there is a frequent occurrence of slopes, cracks, and collapses of nearby buildings, including settlement of adjacent roads, when the construction of underground structures is carried out.

As a result, many social problems are caused by the loss of property, civil complaints, and civil and civil disputes. Therefore, the selection of construction methods and absences for the construction of earth wall temporary facilities in underground excavation is becoming a very important factor.

Conventional wood earthen boards are embedded at fixed intervals in underground excavation work and inserted and fixed between adjacent H piles to stabilize the ground of unconstructed areas and to prevent the scattering of stones and soil due to blasting excavation. It is a construction material to prevent the occurrence of an accident in advance.

Conventionally, it is necessary to check the span of the earthquake temporary pile installation step, which excavates the temporary earthquake temporary pile at a predetermined interval, the excavation stage to excavate to a certain depth, and check the span of the earthquake temporary facility pile of the excavated earth wall, and then cut the wood soil plate with a saw from the top to the bottom. Alternatively, install a wooden earthen board to install a plurality of wood earthen boards by placing them horizontally between the earthenware piles at an angle, and excavation step of digging again to a certain depth, and check the span of the earthenware piling stakes of the excavated earthen walls. Install the wood earthen board by cutting it with a saw and inserting it diagonally between the piles of the temporary furniture and pushing it to the lower part of the wood earthen board already installed on the upper side. Belts and stands across the piers Reinforcement installation step of installing the support for supporting the band, and repeating the above steps to construct the earth plate by completing the underground structure to dismantle the wood earth plate when dismantling the wood earth plate in order from the bottom to the top And, the dismantled mud is made of soil filling step in the space of the temporary pile and wood earthen plate.

However, such a conventional earthenware temporary facility is not completely sealed between the earth plate and the earth plate, and because the groundwater leaks through the gap between the earth plate and the earth plate, the nearby ground head is lowered, causing ground subsidence of the nearby building. There was this.

In addition, since the conventional earth plate is made of wood, the strength decreases, and when a certain time elapses, warpage occurs along the length direction of the earth plate. When rain or snow comes, the water absorbs moisture and increases its own weight. When a long time is long, there are many problems, such as a phenomenon that the earth plate made of wood is corroded and the recyclability is reduced.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, the present invention can not only efficiently discharge groundwater leaking from the side wall of the excavated underground space through the earth plate, but also improves the strength of the earth plate. It is an object of the present invention to provide a construction earth plate structure using rubber tubes that can increase and prevent warpage.

In order to achieve the above object, the present invention assembles the earth plate 100 for a construction engineer for constructing an underground structure in the insertion portion 12 of the H pile 10 which is placed at a predetermined interval in front of the side wall of the excavated underground space In doing

It is configured in the same manner as in the conventional assembling the earth plate 100 for building construction used to construct the underground structure of.

2 to 4, the earth plate 100 of the present invention is composed of a pair of outer plate 22a and inner plate 22b having an accommodating space 21 therein so that it can be opened or retracted in the width direction. A variable wall 20 made of glass fiber reinforced plastic (FRP), the assembly guide 40 is fixed to the inner center of the storage space 21 of the variable wall 20 through which the anchor bolt 30 is penetrated. In addition, the air inlet 55 having a sealing cap 54 is installed on the body, and the outer circumferential surface of the body is formed to be crimped to enable contraction / expansion by air injected into the air inlet 55. Rubber tube member 50 inserted into the inner receiving space 21 of the), a plurality of fixing hook portion 72 is provided with a plurality of fasteners 74 coupled to the fastening hole 75 by the variable wall (20) Fixing member 70 fixed to be positioned at both edges of the), facing each other It is characterized in that the earth construction plate for a construction engineer using a rubber tube further comprises a tension spring 60 for imparting a tension force to pull a pair of the variable wall 20 to be assembled to one side as a unit assembly. .

In the above configuration, the variable wall 20 is composed of a pair of outer plates 22a and inner plates 22b having an accommodating space 21 therein, as shown in FIG. 221 and 222 are assembled to face each other so that they overlap each other so as to overlap each other, so that the outer plate 22a and the inner plate 22b can be opened or retracted in the width direction with a fiber reinforced plastic (FRP; Is produced.

Assembly guide 40 is fixed to the through-hole 23 to be punctured in the inner center of the receiving space 21 of the variable wall 20 is fixed so that the anchor bolt 30 is inserted through the inside.

The rubber tube member 50 has a through hole 51 through which the assembly guide 40 is inserted in the center, and a fixing portion 52 through which a plurality of assembly holes 52a through which the tension spring 60 penetrates are formed at both edges thereof. Is formed, the air inlet 55 is provided with a sealing cap 54 is formed by the air injected into the air inlet 55 to form the outer circumferential surface of the body to be able to shrink / expand to form the variable wall ( 20 is assembled to be inserted into the inner receiving space (21).

As shown in FIG. 4, the fixing member 70 has a plurality of fixing hook portions 72 which fix both fixing portions 62 of the tension spring 60 which are penetrated by the assembly holes 52a of the rubber tube member 50.
