Construction platform and construction method based on reconstruction of old pile foundation

Abstract

The invention discloses a construction platform based on the transformation of old pile foundations and a construction method thereof, which includes: detecting the strength of the bearing capacity of the old pile foundation; Install temporary steel sheet pile caps, support structures, Bailey beams, I20a I-beams, and panels on the top surface of the load-bearing pile foundation from bottom to top to obtain a construction platform for the reconstruction of the old pile foundation; wharf reconstruction is carried out on the construction platform; reverse demolition The construction method of the present invention is simple, low in cost, and produces less construction waste. By selecting a suitable old pile foundation and carrying out transformation treatment on the old pile foundation, there is no need to set up a steel casing for a temporary construction platform, which reduces the difficulty of construction. The construction time is shortened, compared with the traditional construction platform, the construction is faster, the disassembly is convenient, and the cost is low.

Description

technical field [0001] The invention relates to the field of port wharf construction. More specifically, the present invention relates to a construction platform based on old pile foundation transformation and a construction method thereof. Background technique [0002] In engineering reconstruction, there are often projects that need to be rebuilt or remodeled on the basis of old buildings; this kind of project is more difficult than new projects. On the one hand, in addition to demolition of the original Treatment of the foundation of the original building; most of the existing renovation technologies are for the treatment of old factory buildings, old communities, old office buildings, etc. on land. [0003] The existing treatment method is generally to pull out the old pile foundation, clean up the soil, backfill the pile pit of the old pile foundation produced, and then re-construct according to the construction steps of the new building after backfilling; [0004] Ho...

Problems solved by technology

[0004] However, for the old seaport and the old wharf, the original wharf has been in operation for decades, during which objects, components, and even shipwrecks will occur. After a long time, they will be buried under the mud surface, which is difficult to detect with the naked eye, and the structure of the original wharf Part of the connecting components was also buried by silting, forming a complex layer of obstacles on the ground, so it was difficult to clean up the old pile foundation; at the same time, there was a lot of waste generated after the old pile foundation was pulled out and cleaned, and the disposal of the waste was also very difficult. Therefore, there is a need for a construction method based on the reconstruction of old pile foundations for old seaports and wharfs
