High-stability sectional type cast-in-situ bored pile construction method

Abstract

The invention discloses a high-stability sectional type cast-in-situ bored pile construction method, and belongs to the technical field of concrete piles. According to the construction method, innovation can be realized, a sectional pouring mode is adopted, and a double-effect monitoring rod is mounted on a reinforcement cage, and is synchronously pre-buried along with sectional pouring, so that the sedimentation phenomenon of a concrete pipe pile in a foundation environment is effectively improved, along with pouring of concrete, the hydration heat phenomenon of the concrete is utilized for absorbing heat and triggering the anchoring action, high-strength combination with the hole wall is achieved, and meanwhile, the concrete at the upper end and concrete at the lower end are connected, in addition, bending and settlement monitoring can be carried out at the same time when the cast-in-place pile is pre-buried inside the concrete, when bending and settlement happen to the cast-in-placepile, an alarm circuit can be triggered, an alarm signal is sent to the outside, and technicians can take remedial measures in time, so that the stability and the safety of the cast-in-situ bored pile are effectively improved, the construction difficulty is reduced, and the construction cost is controlled.

Description

technical field [0001] The invention relates to the technical field of concrete piles, in particular to a construction method for high-stability segmented bored piles. Background technique [0002] Concrete piles are piles made of concrete (including ordinary reinforced concrete and prestressed concrete). It has the advantages of saving wood and steel, durable, and low cost. It has been widely used in the foundation engineering of hydraulic construction, industrial construction, civil construction and bridges. [0003] Bored cast-in-situ pile refers to the pile hole formed in the foundation soil by means of mechanical drilling, steel pipe extrusion or manual excavation on the project site, and a steel cage is placed in it and concrete is poured into the pile. Different, cast-in-place piles can be divided into several categories such as immersed pipe cast-in-place piles, bored cast-in-place piles and bored cast-in-place piles. [0004] Most of the concrete piles are poured ...

AI Technical Summary

Problems solved by technology

[0004] Most of the concrete piles are poured in one pour to avoid interruption, otherwise the pile will be broken, which will seriously reduce the strength and quality of the concrete pile. The post-strength is not uniform, and due to the heavy weight of the concrete pile, there is a possibility of derailment from the foundation environment after forming, which will lead to uncontrollable settlement and seriously affect the construction quality
