Embodiment Construction

[0053] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings.

[0054] image 3 According to the first preferred embodiment of the present invention, it is a sectional view of a straight pile placed in the entire excavation space under the prestress exerted by the steel tendon, the steel tendon bracket and the anchoring component. The temporary structure applying the prestressed bracing system according to the present invention includes: straight piles 10, supports 21, intermediate piles 30, girders 40, cover plates 45 and cross braces 50, which are the same as the above-mentioned components of the conventional bracing system. However, in the prestressed bracing system of the present invention, a plurality of tendon brackets 11 , anchoring members 12 and tendons 13 are also connected to the straight pile 10 so that the straight pile 10 is prestressed. As a result, the piles can still withstand the additional soil pres...

Abstract

Disclosed herein is a support system that is temporarily placed below ground for preventing collapse of the excavated ground when a subway is constructed or a basement of a building is built. The excavated ground or load is supported by means of supporting members, the supporting members being pre-stressed by means of tensioning members and tendon support members serving to support the tensioning members. Consequently, the number of struts for supporting vertical piles and wales is considerably reduced so that obstacles in the underground space when it is excavated are removed. Furthermore, the constructional efficiency of the underground space is greatly improved, and the cost of construction is sharply reduced.

Description

technical field [0001] The present invention relates to a support system temporarily placed in the ground during the construction of an underground structure to prevent the excavated ground from collapsing, more particularly to a support system capable of aligning vertical piles, braces and / or A prestressed bracing system consisting of main girders such as H-beams or sheet piles prestressing, thereby greatly reducing the number of bracing and intermediate piles, thus improving the construction efficiency and commercial effectiveness of excavation and shoring construction operations. Background technique [0002] It is well known that the excavation work for subway or building foundations begins with excavating a hole along the sideline to a depth specified in the technical drawing, and then installing straight piles into the excavated hole. After the straight piles are installed, some excavation work is carried out first, and then the main beam and cover plate are put in. A...
