Abstract

The invention discloses a foundation pit drilling pile steel supporting structure which comprises a foundation pit cavity. Supporting pillars are arranged on the two sides of an inner cavity of the foundation pit cavity. Insertion rods are fixedly connected to the bottoms of the supporting pillars. The bottoms of the insertion rods penetrate the two sides of the bottom of the foundation pit cavity. A first supporting pipe is arranged on the top of the left side of the inner cavity of the foundation pit cavity, and a second supporting pipe is arranged on the top of the right side of the inner cavity of the foundation pit cavity. Fixing parts are arranged on the left side of the first supporting pipe and the right side of the second supporting pipe, and positioning parts are arranged on thetop and the bottom of the right side of the first supporting pipe. By means of the foundation pit drilling pile steel supporting structure, due to the fact that the foundation pit cavity, the supporting pillars, the insertion rods, the first supporting pipe, the second supporting pipe, the fixing parts, the positioning parts, positioning plates, positioning pillars, positioning holes and screw pins are arranged and are matched, a good supporting effect is achieved, foundation pit collapse cannot be caused, meanwhile, the structure is simple, demounting and adjusting are facilitated, and the construction steps and the construction cost are reduced.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a foundation pit bored pile steel support structure. Background technique [0002] In deep foundation pit support, in order to ensure the stability of the foundation pit, internal support support structure is often used. The internal support support structure is generally composed of support piles, vertical support columns and horizontal internal support beams. Currently, the commonly used vertical support The column is a section steel structure column, and the cast-in-place pile constructed to a certain depth under the pit before excavation of the foundation pit plays a role of embedding, and then the steel structure column welded on site is inserted and fixed on the top of the cast-in-place pile. [0003] At present, the existing foundation pit bored pile steel support structure has the following disadvantages: the support effect is poor, which will cause the foundation pi...
