Problems solved by technology
[0003] In order to overcome the shortcomings of the existing technology, a construction method for the early demolition of inner support partitions in deep foundation pits is now provided to solve the problem of dismantling the traditional support beams in the foundation pit after all the construction of the basement concrete structure has been completed and reached the design strength. Only then can it be dismantled, leading to the problem of long construction period

The invention discloses a partition early-dismantling construction method for inner supports of a deep foundation pit, which is characterized in that a box-type back-to-top inclined strut is arranged at a post-cast strip pouring space position below three inner supports in the middle of the deep foundation pit, the box-type back-to-top inclined strut is connected with a basement structure, and meanwhile, the box-type back-to-top inclined strut is connected with the inner supports and forms a certain included angle with the inner supports; the box type back-to-top inclined strut is welded through the upper buried plate and the lower buried plate to integrally form a triangular support back-to-top form, so that partition support disassembly and rapid support disassembly in a deep foundation pit are achieved, the construction efficiency of a basement structure is improved, and the construction period is shortened. The problem that the construction period of a project is long due to the fact that a traditional supporting diagonal beam in the foundation pit can only be dismantled after a basement concrete structure is completely constructed and reaches the design strength is solved.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for early demolition of inner support partitions of deep foundation pits. Background technique [0002] The premise of the traditional basement support beam removal is that the basement concrete structure must be completed and reach the design strength before the internal support beam removal can be carried out. Therefore, there is a problem of long construction period. Contents of the invention [0003] In order to overcome the shortcomings of the existing technology, a construction method for the early demolition of inner support partitions in deep foundation pits is now provided to solve the problem of dismantling the traditional support beams in the foundation pit after all the construction of the basement concrete structure has been completed and reached the design strength. Only then can it be dismantled, leading to the problem of long ...
