Description

Technical Field [0001] The present invention relates to a method of constructing a structural structure of a well-

The present invention can assemble a plurality of retaining wall modules manufactured in a unit module manner for different slope heights in different sites by a vertical stacking method and can quickly and easily construct them. As a result, the same stone materials as rocky mountains, The present invention relates to a method of constructing a building structure in a well-concentrated area including Jeju, which is characterized by securing a solid retaining wall supporting force to the slope of the ground.

In addition, the present invention solves the problem of rainwater inflow (leakage) of the wall caused by frequent rainy season including rainy season. This is because a pair of PC walls are erected on a foundation floor, And a waterproof jaw protruding from the foundation floor is formed between the inner and outer water walls to prevent water inflow (leakage of water) from the outside from the outside, And a metal plate or a PVC panel having a water-pressure-dispersed structure is provided between the joints when connecting to the adjacent neighboring PC walls, thereby greatly improving indoor and outdoor waterproofing of the structure.

Generally, a structure or a structure is formed after a foundation (floor) after a terrage (civil engineering work), and an outer wall is constructed by an RC concrete method using a mold thereon, and a slab is formed at the upper end of the outer wall.

Therefore, in the outer wall construction by the RC method in the related art, the reinforcing bars are firstly laid in order to set up the wall, the concrete is installed in the formwork after the concrete is installed and the concrete wall is cured, It is troublesome to install and remove scaffolds one by one, and there is a disadvantage that the construction period is lengthened and the construction cost is increased.

In addition, when the height of the outer wall is increased due to the high height of the floor, the side pressure (bending moment) acting on the form becomes considerably large, which may cause a safety problem. It became a cause.

Therefore, in the case of a large space structure such as a storage tank, an underground parking lot, and a warehouse, an outer wall having a floor height of about 10 to 20 m is required. In this structure, the RC construction method has a long construction period, The workability and productivity of various construction materials are greatly decreased, and the construction cost is greatly increased.

In order to improve this, recently, as shown in Patent Application No. 10-2010-0084034, a PC member is manufactured and assembled in the field. However, since the PC member has a prefabricated structure, water formed from the slurry side , Which deteriorates the quality and durability of the structure, and a practical improvement is urgently required by those skilled in the art.

On the other hand, the prefabricated concrete retaining wall is constructed such that it corresponds to the installation height of the retaining wall at the construction site of the retaining wall, and the preliminary concrete block is laid sequentially in the order of 5 to 10 cm on the floor, The retaining wall is installed on the road side and supports the filled soil on the back surface to prevent the collapse.

However, as the height of the retaining wall increases, the retaining wall must have a larger width of the base plate in order to stabilize the conduction, sliding phenomenon, and the supporting force. Accordingly, the excavation amount of the base surface increases, There is a problem that the construction is troublesome and costly and a large amount of excavation of the foundation surface causes destruction of the surrounding environment.

In other words, the conventional retaining wall construction method is disadvantageous in that it is difficult to construct and the installation period is long because disassembly of the scaffold for reinforcement installation during foundation and wall construction, dismantling of the formwork for concrete pouring, I have.

In addition, since the installation and curing are performed at a site where the temperature change is not constant, the quality is not constant and thus it is difficult to secure the quality.

In the case of retaining walls, it is common to design the cantilever with respect to the wall and foundation by using the cantilever as the base earth pressure and the overburden load acting as the horizontal and vertical loads on the wall and foundation. However, It is designed as a sub-wall to connect and support the base end and the ceiling edge of the retaining wall, and the foundation is provided with a shear resistance key installation to resist horizontal force. However, when the sub-wall and shear key are installed on site, the foundation trench, formwork, The construction is complicated.

Also, considering that the retaining wall is installed in a place where the change of the terrain is frequent, construction according to the height and the section change is complicated.

In addition, when the height of the retaining wall is high and the overburden load is large, the size of the bottom plate increases, and the amount of the ter- minator and the range of the paper compensation increase.

1. Patent Application No. 10-2010-0084034 (filed on Aug. 30, 2010)
