Abstract

PURPOSE: A simple earth retaining method using a PC wire is provided to obtain safety with respect to the lower displacement and sliding, thereby easily performing a task because a free space is obtained when installing a drain pipe of large diameter and a concrete box. CONSTITUTION: A simple earth retaining method using a PC wire comprises next steps. A steel beam(103) in which a PC wire is inserted is casted into the underground. A panel is installed in order to resist earth pressure. A strut(104) crossing structure steels is installed. The steel beam casted into the underground, the PC wire, and the PC wire of the strut are connected and pre-stress(106) is applied to the same, thereby enduring the earth pressure.

Description

Simple Soilwall method using the PC Strand}

The present invention relates to a simple clogging method that can be used for sewage pipe construction or excavation of a relatively low ground. Specifically, a steel beam is installed in the ground and a panel is installed to resist earth pressure. By installing a brace that crosses the steel and steel, BEAM's PC steel wire embedded in the ground and PC steel wire of the brace are applied to reduce the displacement of the lower steel with high earth pressure and to be safe to sliding without installing the brace on the lower part. It is about the simple soil construction method that I configured.

       In order to excavate sewage pipes or to excavate relatively low ground, simple earth barriers are installed. Unlike the H-PILE mud-blocking method, the simple mud-blocking method is installed only up to the trench without breaking up and entering the bottom.

Figure 1 shows a general cross-sectional view of the conventional soil mud method in the ground. Underground earth pressure (FIG. 2) grows toward the bottom, but when the dig is dug up and down, such a simple earthquake method has the disadvantage of installing a brace on the bottom side to reduce the occurrence of ground displacement and sliding. This is because of the braces, when installing large sewage pipes, concrete boxes, etc., there is a lack of work space, and when dismantling some braces and install conduits. This can cause safety problems and make work less efficient.

The present invention was developed to overcome the limitations of the prior art as described above, in order to prevent the displacement and sliding of the lower BEAM due to the earth pressure, install the beam 103 is inserted into the PC steel wire and connected to the brace 104 This is to give a pre-stress (106) to the resistance to the lower earth pressure without installing a brace on the lowermost side.

In the present invention, in order to achieve the above object, the PC steel wire is inserted into the beam and the PC steel wire is inserted into the brace, it is composed of a pressure plate and tensioner that can be applied to the tension.

When using the simple mud wall according to the present invention, the steel wire in advance to resist the earth pressure by tensioning the wire, so there is no need to install a lot of braces, the installation of large sewage pipes or concrete boxes with a large space is easy to work and the work efficiency is exhibited.

1 is a conventional general dirt film construction method.
Figure 2 is a general soil pressure distribution.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings. The present invention has been described with reference to the embodiments shown in the drawings, which are described as one embodiment by which the technical spirit of the present invention and its core configuration and operation are not limited.

1 is a cross-sectional view of a conventional simple soil construction method. Consisting of the beam 101 and the brace 102 to be inserted into the ground and the installation interval is installed by examining the structure, but is approximately 1.0m ~ 1.2m tightly installed. Figure 2 shows the earth pressure distribution of the general ground. Towards the lower ground, the earth pressure distribution is larger, so the largest earth pressure at the bottom is applied.

3 is a cross-sectional view of a simple soil membrane method according to the present invention. After installing the BEAM (103) connected to the PC steel wire and installing the brace 104, after connecting the PC steel wire through the connecting socket 108 and tensioning the tensioner plate 105 from the tensioner 106, due to the tension of the PC steel wire Numeral 103 is forced to the back side to resist the working earth pressure.
