Foundation reinforcement treatment method

Abstract

The invention belongs to the technical field of project construction, and discloses a foundation reinforcement treatment method. The foundation reinforcement treatment method comprises the following steps of surveying a peripheral area of a foundation, and determining whether the foundation reinforcement property is ground reinforcement or underground reinforcement; determining a foundation weak area, and removing the foundation weak area; performing prepressing treatment on the geotechnical engineering foundation by a vacuum prepressing construction method; tamping the foundation by using a rammer, and compressing soil layer pores of the foundation in a rock-soil area; determining a reinforcement method; and performing hole drilling by a pile machine, inserting a grouting pipe with a nozzle into a preset position of a soil layer, and performing foundation reinforcement by a high-pressure jet grouting method. The foundation reinforcement treatment method provided by the invention has the advantages that the vacuum prepressing treatment method is reasonably used; pore water in the rock-soil body of the foundation is enabled to be rapidly discharged; the solidification time of the soil body is obviously shortened; the foundation reinforcement quality is enhanced; through the high-pressure jet grouting treatment, the bearing capacity of the geotechnical engineering foundation is enabled to be obviously improved; and the foundation reinforcing effect is better.

Description

technical field [0001] The invention belongs to the technical field of project construction, and in particular relates to a foundation reinforcement treatment method. Background technique [0002] At present, the foundation is a very important part of construction, road and railway engineering. In actual engineering, the natural foundation is often weak and cannot meet the requirements of bearing capacity and settlement, so the foundation needs to be reinforced. The foundation reinforcement methods mainly adopted at this stage include replacement, compaction, compaction, drainage, cementation, reinforcement, etc. These ground treatment methods consider bearing capacity requirements or settlement requirements separately, the treatment cost is high, and the treatment effect is difficult to take into account both the bearing capacity and settlement requirements. [0003] Through the above analysis, the existing problems and defects of the existing technology are: the existing ...
