The invention relates to the technical field of foundation pit construction, and discloses a construction method for a support structure at a horseway in a foundation pit, comprising: constructing an enclosure structure in a construction area where the support structure is located at the horseway; after the enclosure structure reaches a preset strength, Excavate the earthwork in the construction area to the bottom elevation of the support structure; construct the ring support beams in the support structure from bottom to top in the excavated construction area, and carry out backfilling at the carriageway. The invention provides a construction method for the support structure at the horseway of the foundation pit. Firstly, the enclosure structure at the horseway is constructed, and the construction method of the ring support beam at the horseway is adopted, and soil is backfilled at the horseway while the ring support beam is being constructed. Greatly reducing the impact on the construction period and cost increase caused by the relocation of the foundation pit earthwork track is conducive to the rapid construction of foundation pit engineering, especially deep foundation pit engineering, and reduces costs.
Description
technical field [0001] The invention relates to the technical field of foundation pit construction, in particular to a construction method for a support structure at a foundation pit horseway. Background technique [0002] In the construction of deep foundation pit engineering, problems such as ground structure settlement deformation and supporting structure lateral displacement often occur. In this regard, in order to improve the stability of deep foundation pits, it is often necessary to take some foundation pit support measures. At present, the commonly used support forms include concrete enclosure piles, the combination of reinforced concrete inner ring support beams and enclosure piles, and enclosure piles. Combination with transverse reinforcement, etc. [0003] The deep foundation pit support structure generally adopts the ring support structure set in the foundation pit to support the foundation pit evenly and firmly. The traditional construction method of the ring...
