Construction method of steel casing for ecological river foundation reinforcement

Abstract

The invention discloses a construction method of a steel casing for ecological river foundation reinforcement, comprising the following steps: 1) construction preparation; 2) installation of a positioning base; 3) installation of a limit sleeve; 4) a tapered guide bucket 5) The installation of the stopper; 6) The embedding of the steel casing. The design of the overall structure of the present invention is reasonable, and the construction of the steel casing can be guided through the design of the auxiliary bracket. The positioning of the auxiliary bracket and the pile position coincides to ensure that the center of the steel casing is consistent with the center of the pile location, improving the construction quality, and at the same time The auxiliary bracket can limit and restrain the steel casing during the entire construction process of the steel casing to ensure the verticality of the steel casing during the burying process, thereby effectively avoiding the inclination deviation during the construction of the steel casing and improving the final pile hole The quality of the pile can effectively avoid the deformation and collapse of the pile hole, and improve the construction safety performance.

Description

technical field [0001] The invention belongs to the technical field of steel casings, and in particular relates to a construction method of steel casings for ecological river foundation reinforcement. Background technique [0002] In the pile foundation reinforcement of the foundation, the steel casing plays a role in positioning and guiding the hole during the drilling process of the pile foundation, preventing the hole from collapsing, and maintaining the groundwater level. In actual operation, the verticality of the steel pipe often deviates during the embedding process, resulting in a deviation between the actual pile hole and the center of the pile position that is greater than the set value, increasing the collapse of the pile hole probability, resulting in certain security risks. Moreover, when the verticality deviation of the steel pipe is large, the drill bit will drill downward under the guidance of the steel casing, which may cause serious adverse effects on the ...

Problems solved by technology

In actual operation, the verticality of the steel pipe often deviates during the embedding process, resulting in a deviation between the actual pile hole and the center of the pile position that is greater than the set value, increasing the collapse of the pile hole probability, causing certain security risks

Moreover, when the verticality deviation of the steel pipe is large, the drill bit will drill downward under the guidance of the steel casing, which may cause serious adverse effects on the verticality of the entire hole and even form a waste hole, increasing the construction cost and construction period.
