Abstract

The invention relates to a metro station deep foundation pit combined type support construction method which comprises the following steps: 1, prefabricating a pile top beam and a support beams I; 2 carrying out support pile construction; 3, laying the pile top beam; 4, laying the support beam I; 5, excavating foundation pit soil mass; 6, laying a support beam II; 7, laying a slant water drain pipe; 8, adding a rib layer and a mortar layer; and 9, laying a wall surface water drain pipe. The metro station deep foundation pit combined type support construction method has the following benefits:the pile top beam and the support beams I are prefabricated according to the design requirements, so that the site construction efficiency is improved, and the project construction period is shortened; in addition, a displacement control body and an expansion filling body are arranged between the connected support beams I to apply jacking pressure to the support beams I and to reduce flexural deflection of the support beams I; and a rib plate and a connecting screw rod I are pre-arranged on the outer side of a support pile reinforcement cage, so that the pulling resistance of the connecting screw rod I is effectively promoted, the construction difficulty of a rear connecting piece is lowered, and the site construction efficiency is improved.

Description

technical field [0001] The invention relates to a construction method for deep foundation pits, in particular to a composite support construction method for deep foundation pits in subway stations, which is convenient for on-site assembly, good in structural integrity, and high in construction efficiency. It belongs to the field of civil engineering and is suitable for composite deep foundation pits. Support construction works. Background technique [0002] In the construction of deep foundation pit engineering of subway stations, problems such as ground structure settlement deformation and support structure lateral displacement often occur. In this regard, in order to improve the stability of deep foundation pits of subway stations, it is often necessary to take some foundation pit support measures. Combination with transverse reinforcement, etc. [0003] In the prior art, there is a support construction technology of row piles and inner support, which is characterized in...
