Method for constructing inclined bracing supporting system and foundation bottom plate simultaneously

Abstract

The invention discloses a method for constructing an inclined bracing supporting system and a foundation bottom plate simultaneously. An inclined bracing lower supporting point is arranged at the bottom of the foundation bottom plate or a bearing platform cushion layer, original structure engineering piles are used for resisting horizontal force of a supporting structure; sloping and soil reserving are conducted on the side of a foundation pit, and earth in the center of the foundation pit is excavated; earth is locally over-excavated at the position where an inclined bracing lower additional block needs to be arranged; the lower additional stress plate and a bearing platform are poured in an over-excavating area, multiple engineering piles form a whole through the additional plate, a bracket is pre-arranged on a plate strip, and a steel plate is embedded in the bracket; an inclined bracing is erected; bottom plate or bearing platform concrete is poured to the sides of the piles, and a body structure is constructed upwards; and after a top plate of a basement structure is constructed and peripheral soil is backfilled to the ground surface, the inclined bracing is cut off. By means of the method, the problems that due to the fact that the inclined bracing needs to be arranged in the past, the bottom plate of the center area needs to be poured firstly, a construction joint needs to be arranged on the bottom plate, and secondary earth excavating needs to be conducted on earth at the lower portion of the inclined bracing are solved; and the method is easy to operate, the construction period is shortened, and convenience is achieved.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to an oblique throw support system and a method for simultaneous construction of the system and the base plate. Background technique [0002] With the acceleration of urbanization in our country, the development and utilization of underground space has developed rapidly, and foundation pit engineering has become more and more common. Therefore, the enclosure design and construction technology of foundation pits have also been continuously developed. The foundation pit project is a temporary support structure, which only works during the excavation stage of the basement. Therefore, in the foundation pit support design, it is generally necessary to consider the surrounding environment, soil conditions, foundation pit excavation depth, structural safety, project cost, and construction convenience. Factors such as construction period and construction period shall consider the for...
