Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a retractable retention structure and a construction method using a lightweight lapping plate and a pedestal,

More particularly, the present invention relates to a method and apparatus for constructing a ground structure, such as a water supply and drainage pipe, a transmission line and a gas pipe line, in a new construction and maintenance of an underground channel, The present invention relates to an installation type retention structure and a construction method using the same.

Generally, it is necessary to make terrain of ground for construction and repair of pipelines such as water supply and drainage, and it is important to carry out the grounding work for such pipelines in a narrow roadway, such as a residential area, .

Therefore, it is a common practice to install a lounger to prevent pedestrians and vehicles from falling.

The earth retaining structure according to the related art includes a plurality of supports provided on both left and right side wall surfaces of the underground excavator with a certain distance therebetween, a soil plate installed between the supports, a brace supported by the supports on both sides, As shown in Fig.

Patent Document 10-1026836 discloses a structure in which an upper excavating portion having a transverse width wider than a lower excavating portion from a starting position of the lower excavating portion to the ground is formed; A bottom wall formed by excavated soil walls of the lower excavation section and including a thumb pile disposed at an interval in the longitudinal direction and a soil plate sandwiched between the vertically disposed thumb piles; A supporting angle extending in the longitudinal direction and bent in a bend is provided on each of the step portions existing in the ground due to the lateral width difference between the lower excavating portion and the upper excavating portion; A transverse mold to support the secondary panel is disposed laterally across the upper excavation so that the opposite ends thereof rest on the support angles; Since the bottom panel is disposed on the upper part of the horizontal mold, the bottom panel is disposed on the upper part of the horizontal mold to cover the upper excavation part. Since the supporting angle is only settled on the ground, there is a problem in that the fluidity of the retaining walls is increased due to a large fluctuation even in a small settlement of the ground due to the lack of a supporting base.

In addition, since the support angle and the pile are separated from each other, the structural stability of the pile foundation is secured by supporting the pile support on the thumb pile at the time of installation. However, the underground obstacle buried in the existing urban residential area , Gas pipes, communication pipes, etc.), it is difficult to secure the safety of the lower drilling rig due to the difficulty in installing the transverse strut, and safety accidents and human accidents due to the collapse of the drilling rig are generated.

Patent No. 10-1026836

The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a water supply system capable of constructing on a narrow road such as a residential area, , Gas pipe, communication pipe, etc.), it is possible to secure the structural safety by preventing the collapse of the lower excavation part to improve the robustness and safety of the earthquake. It is aimed to provide an installation type pavement and a construction method using a pillar and a pedestal.

The present invention relates to an excavation type earth retaining structure comprising: a plurality of support columns erected on both left and right sides of a ground excavation unit with a predetermined distance therebetween; A soil plate installed at one or more stages between the struts; A pedestal installed at an upper portion of the struts; A cross bar arranged at a predetermined distance from each other and supporting the pedestals, the cross bars being arranged in a direction transverse to the pedestals; And a pedestal mounted on the pedestal between the transverse beams to support the pedestal. The pedestal is mounted on a bottom surface of the pedestal by means of a submerged trough and supports a bottom of the pedestal on a bottom of the pedestal, And the upper and lower flat plates are interposed between the cross beams and both sides in the width direction are seated on the pedestal.

And the pedestal is connected to the support through the support link.

And the pedestal is fixed to the ground through a fixing key.

The present invention relates to a method of constructing a retention type earth retaining structure via a lightweight base plate and a pedestal, A second step of constructing a pillar on both left and right sides of the excavating part formed through the first step with a predetermined distance from each other along the forward and backward directions; A third step of installing a soil plate between the pillars constructed through the second step; A floor formed of a bottom surface seated by a ground wave device and a wall portion formed on one side of the widthwise side of the bottom portion is installed on the top of the pillars, ; A fifth step of installing a plurality of beams in a direction transverse to the pedestals on both sides installed through the fourth step; A step of installing a flat plate in a space between the cross beams installed through the fifth step such that the left and right sides of the flat plate are seated on the bottom of the pedestal so that the pedestal is installed at the same height as the cross bar and the pedestal .

According to the present invention, it is possible to construct on a narrow roadway such as a residential area through a stable installation of a small-sized but also a small-sized, but also an open-type, It prevents a fall accident, and it can be installed at the same height as the roadside with the beam, so that it is possible to shorten the air flow and reduce construction cost.

In addition, when the support is connected to the support to support the support, the stability of the retaining structure is secured by keeping the construction state without the subsidence, and if the support is fixed to the ground and the behavior or settlement of the ground occurs, . &Lt; / RTI >

In addition, due to the underground buried in the existing urban residential area, there is an effect of preventing the collapse of the hypothetical case and human casualties through the pedestal and the pillar connection part due to the unconfirmed structural safety of the lower pedestrian bridge due to the non-installed pedestal.
