Description

PH pile and its using the same soil cement wall construction methode

The present invention relates to a PHC pile and a method for constructing a retaining wall using the same, and more particularly, a straight surface is formed in the longitudinal direction on the outer circumferential surface of the PHC pile, and the nut for fixing the bolt is fixed to the straight surface. A built-in or bolt fixing nut is embedded and fixed to a straight surface to form a PHC pile that does not separate the steel plate, and the PHC pile is used to install a temporary soil wall on a continuous excavation surface that must support lateral pressure such as earth pressure or water pressure. Another aspect of the present invention relates to a pile of P.C pile for wall piles and a method of constructing a retaining wall using the same.

There are two main types of wall walls: temporary wall and permanent retaining wall.

The temporary clamshell type is constructed for the purpose of constructing underground structures to resist side pressures such as earth pressure and water pressure during underground excavation work, and for the purpose of subsidence of surrounding ground and protection of adjacent structures. Consists of the support of the wall to prevent the fall of the wall, it is classified according to the type and method of the material and support of the gasket wall.

Soil Cement Wall (SCW: Soil Cement Wall), H- section steel + earth plate (wood), sheet pile wall, cast-in-place concrete pile (CIP: Cast In Place) ), And underground continuous walls (Diaphragm Wall, Slurry Wall), and the type of support, such as the brace method, the ground anchor method, the soil nailing.

In general, the H-beam + earth plate is installed where no groundwater exists, and the remaining method is used where the groundwater exists.

The retaining wall composed of H-beam + earth plate is drilled into the ground using auger equipment, and the H-beam is installed along the digging surface boundary at predetermined intervals, and at the same time, the earth plate is sandwiched between both H-beams. As a construction method to go down and use it as a retaining wall, wood is mainly used as a soil plate.

The steel sheet pile wall is a method of forming sheet wall temporary steel by continuously installing sheet pile steel in the ground with a vibratory hammer drill to bite each other.

The cast-in-place concrete pile (CIP) is drilled on the ground using auger equipment, and the H-beams are installed in the recesses along the digging surface boundary at predetermined intervals. It is a method of forming temporary walls by making piles by casting cement mortar or concrete on-site.

The main heat-type cement cement wall (SCW) uses a three-axis auger to drill three grounds of the ground and add cement mortar and stir to form a soil cement mixing pile in the ground. It is a method of forming a temporary wall with a column-type soil wall while repeating the construction to bite one by one.

In order to prevent the collapse of the excavation surface and the penetration of underground water, the underground continuous wall excavates the ground of the wall part while inserting the stabilizer (bentonite), inserts the reinforcing reinforcing bar network, and casts concrete to form the reinforced concrete continuous wall in the ground. It is a construction method.

In addition, the permanent retaining wall type blocks a slope or a hill behind a horizontal surface to be stopped for the purpose of constructing an exposed structure such as a structure or a road with a vertical wall to resist side pressure such as earth pressure and water pressure, and to be adjacent to the settlement of the surrounding ground. It is constructed for the purpose of protecting the structure. It consists of a retaining wall directly contacting the soil and a support for supporting the wall to prevent it from falling, and is classified according to the material and the form and method of forming the retaining wall.

The retaining walls that are widely used today are gravity retaining walls made of concrete and stable by their own weight, the front walls, which are vertical walls acting as cantilevers, and the front and rear plates, which are the front part of the base plate. The cantilever retaining wall, which is composed of a cantilever retaining wall and the bending moment of the front wall of the cantilever retaining wall increases, so that the thickness of the bottom becomes thick, there is a sub-wall retaining wall in which the front wall or the rear wall is disposed to reinforce the front wall.

Meanwhile, a method of using a PHC pile, which is a kind of ready-made concrete pile, has been proposed in place of the pile in the soil wall. In order to use the PHC file as a retaining wall, it is necessary to solve the installation problem of the bracket for supporting the belt. That is, in the case of the conventional CIP or SCW, the ground is excavated to remove concrete from the exposed pile, and the surface is picked to expose the H-beam inserted into the stress bearing material, and then the bracket is welded and installed using the H-beam. However, since the PHC file is made of concrete only, there was a problem that the conventional CIP or SCW method cannot be applied as it is.

In order to solve the problems of the construction of the conventional wall-mounted piling wall as described above, the Republic of Korea Patent No. 10-1078080 has been proposed 'sock wall and the construction method using the support pile and ground reinforcement'.

Patent No. 10-1078080, the back of the arc-shaped installation member in close contact with the cylindrical support pile, and fastening the mounting member and the support pile to the bolt hole while passing through the bolt, and then fixing the belt to the installation member Alternatively, the end of the support is positioned between the support pile and the mounting member, and the mounting member and the support and the support pile are fastened and fixed to the bolt hole while passing through the bolt, and then the seat is fixed to the support belt. to be.

However, if the incoming pile is not consistently level, the bolt hole of the support pile also causes a step, so when installing the support that serves as the bracket support bracket, a reinforcement base for adjusting the height is required. Since a space equal to the thickness of the support hardware is generated between them, it is necessary to fit the arc-shaped installation member that compresses and fills this space. In this case, the bolt head is unreasonable due to the arc-shaped member processing. As a structure that can reach the strip, there is an unstable problem that the strip is compressed to the support pile.

In order to solve the above problems, the present inventors have proposed the Republic of Korea Patent No. 10-0973601, 'bracket support bracket of the earth wall wall and the digging method using the same'.

Patent No. 10-0973601 has a flat iron portion on the H-shaped pile or a ready-made concrete pile surface of the exposed soil wall, and leg portions that are bent and extended at right angles from the flat iron portion, and a long hole for bolt insertion is formed in the flat iron portion. The leg portions may include a first end portion inserted into a fixed channel formed in at least one hole and a space surrounded by the flat iron portion and the leg portions, a second end portion inserted into the hole formed in the leg portions, and the first end portion. It is a device for fixing a bracket consisting of a pair of support bending muscles having a multi-stage bent portion bent in multiple stages while connecting the second end.

However, in the application of the registered patent No. 10-0973601, it is possible to recycle and shorten the working time, but if the inclined state of the wall pile is turned back even a little without looking directly to the excavation surface, purchase When tightening the bracket bolt to the nut, there is a problem in that the bent reinforcing bar is installed with its angle turned back.

In addition, the existing PHC wall pile has a circular cross-section with its outer circumferential surface as the point of contact with the strip, and the point-to-face connection is inevitable. There is a problem in that it is delivered in the wedge shape causing stress concentration.

In addition, the inventor of the present invention, the Republic of Korea Patent Registration No. 10-0975033 has proposed a 'construction method of the wall of the earth using P. C pile'.

Patent No. 10-0975033, the hat beam for integrally fixing the top of the wall pile is made of H-shaped steel, the abdomen is provided with a plurality of grouting holes and a connection device for more firmly combined with the pile As the construction method of the retaining wall using the PI stakes, characterized in that a plurality of connecting holes are formed, the connection device is a hollow tube coupled to the headboard and the lower surface of the headboard and the filler filled in the interior of the hollow tube. It is to include.

However, Patent No. 10-0975033 has a problem in that the lifting work of the wall pile is not smooth and the working time is long since there is no lifting ring on the wall pile formed of concrete.

In addition, because the bolt holes are coupled to the wall piles are formed to be spaced apart at regular intervals, if the height of the plurality of wall piles buried in the ground is not correct, the band through the mounting member fixed to the wall piles can not maintain the horizontal In addition, there is a problem to reinforcement, and the wall pile upper surface has to be fixed using steel or reinforced concrete, there is a problem that the wall pile exposed surface must be cut to maintain the horizontal surface if the horizontal surface does not maintain horizontal.

In addition, to integrate the pile by covering the upper portion of the pile by using the hat beam of the H-beam, there is a difficult problem, such as forming a large hole in the hat beam of the H-beam to be fixed to the internal hollow hole.

In view of the above-described conventional defects as described above, an object of the present invention, by forming a lifting guide member that is coupled to the lifting ring and the auxiliary wire at the end of the pile can safely and smoothly the lifting operation of the pile.
