Embodiment 1

[0042] refer to Figures 1 to 4 , the temporary soil layer support device according to the first embodiment of the present invention includes: a cross brace 20, which is integrally coupled to a retaining wall (not shown), to be vertical to the rectangular area during the excavation work. The excavation parts are installed in a parallel manner and support the earth pressure; a set of intermediate connecting beams 100 traverse along the side of the retaining wall and support the earth pressure transmitted from the retaining wall; The middle coupling beam set 100 and the corresponding cross braces 20 are supported obliquely so as to be connected together with the middle coupling beam set 100 and the corresponding cross braces 20 in a triangular structure.

[0043] More specifically, the intermediate connecting beam group 100 includes a plurality of connecting beams, and has a special structure, wherein each intermediate connecting beam is connected to the cross brace 20 in such a w...

Embodiment 2

[0063] The temporary soil layer support device according to the second embodiment of the present invention further includes a corner connection structure using the triangular support structure employed in the temporary soil layer support device according to the first embodiment of the present invention. In this case, the temporary soil layer support device can improve the efficiency of space utilization and the ability to withstand earth pressure by simplifying the structure.

[0064] The temporary soil layer support device according to the second embodiment of the present invention further encloses the corner connection structure, which adopts the above-mentioned triangular support structure. refer to Figures 5 to 8 , according to the second embodiment of the present invention, the temporary soil layer support device includes: a support wall 510, which is installed in parallel with the vertical excavation part during the excavation work; integrally coupled to the retaining ...

Embodiment 3

[0082] The temporary soil layer support device according to the third embodiment of the present invention further includes a corner connection structure, which is arranged in a row at each corner and integrated in a truss structure when excavation work for constructing an underground structure is performed. , suitable for uniform transmission of horizontal loads, so that sufficient capacity to withstand bending loads is obtained using coupling beams.

[0083] refer to Figures 9 to 13 , according to the third embodiment of the present invention, the temporary soil support device includes: coupling beams 1100, which are obliquely arranged in rows at each corner when performing excavation work for constructing underground structures, and the two ends are supported supported on the wall 1010; and at least one connecting plate 1200 interconnecting the upper or lower surfaces of adjacent coupling beams 1100 using coupling members.

[0084] More specifically, the connecting plate 120...

Abstract

A temporary soil sheathing apparatus supports a set of intermediate bracing beams in a triangular supporting structure during pit excavation work for constructing an underground structure, so that it can satisfactorily support soil pressure. Thus, it is possible to prevent space from being reduced by a complicated supporting structure, reduce construction costs through reduced use of materials, and increase work space to improve productivity. The temporary soil sheathing apparatus simplifies a corner connecting structure, and reinforces ability to withstand the soil pressure transmitted from the bracing beams and wales. Thereby, it is possible to prevent space from being reduced by a complicated supporting structure, reduce construction costs through reduced use of materials, and increasework space to thus improve productivity.

Description

technical field [0001] In general, the present invention relates to a temporary soil support device, and more particularly, to a temporary soil support device capable of increasing earth pressure through structural simplification during excavation work for constructing an underground structure Affordability. Background technique [0002] It is known to those skilled in the art that in subway construction or excavation work to form the foundation of a building, holes are drilled to a predetermined depth in a designated area and then vertical piles are inserted into the holes. After the pilings have been inserted, the ground will be partially excavated and the wide I-beams and lining will be installed. After the liner is installed, the rest of the ground will be excavated, with repeated hitch beam installations during the excavation process. Therefore, in order to design such a temporary structure, it is necessary to repeatedly calculate the earth pressure and load acting on...
