Engaging type stress release structure and construction method thereof

Abstract

The invention discloses an engaging type stress release structure and a construction method thereof, and relates to the field of building foundation engineering. The engaging type stress release structure and the construction method thereof aim at solving the problems that an existing excess pore water pressure dissipation effect is not obvious, and pore collapse is prone to occurring and soil deformation exists in the existing pore forming process. The engaging type stress release structure adopts an engaging type sand pile wall formed by the engaging of sand piles constructed first and sandpiles constructed later, the sand piles constructed first and sand piles constructed later can play a role of stress release holes, and the engaging type sand pile wall is positioned between a protected object and a soil squeezing construction area, so that sand pile stress release holes which are originally and independently distributed are combined into the engaging type sand pile wall, therebycompletely blocking possibly produced excess pore water pressure passages and better protecting the protected object. In addition, the sand piles constructed first and the sand piles constructed lateradopt steel sleeves to protect the walls so as to avoid a pore collapse phenomenon during the sand pile construction, and thus a better role is played in deformation control and protection of protected objects such as underground buildings and structures and underground pipelines.

Description

technical field [0001] The invention relates to the field of building foundation engineering, in particular to an occlusal stress release structure and a construction method thereof, which are used for dissipating excess pore water pressure generated by soil squeezing construction in the field of foundation engineering. Background technique [0002] Stress relief holes are widely used because they can be used to solve the excess pore water pressure that may be generated during the construction process of static pressure piles and high-pressure jet grouting piles, thereby reducing the impact on surrounding underground structures and pipelines. Under construction of urban infrastructure. The basic principle of the stress relief hole is to dissipate the excess pore water pressure generated by the soil compaction construction through the vertical drainage channel of the sand pile through the vertical sand piles arranged between the protected object and the soil compaction constr...
