Description

Technical Field

[0002] Interlocking piles for foundation pit support are formed by interlocking reinforced concrete piles and plain concrete piles. They are mainly used to resist lateral displacement of the soil and provide support force, and are an important component in underground engineering construction.

[0003] Chinese patent CN219319767U (publication date: July 7, 2023) discloses a verticality control device for interlocking piles in foundation pit support, including a drilling rig, a first theodolite, and a second theodolite. This patent uses two theodolites to vertically determine two reference points on the drill rod, forming a three-dimensional image between the two theodolites and the drill rod. If the verticality exceeds the specifications during rotary drilling, correction can be performed. However, this patented technical solution requires a significant amount of manpower for measurement and correction during verticality control, resulting in high labor costs.

[0004] Chinese patent CN215760433U (publication date: February 8, 2022) discloses a template structure for a concrete guide wall of interlocking piles in foundation pit support. The template structure is composed of multiple combined units, each of which includes a central arc-shaped module unit and semi-circular arc-shaped module units symmetrically arranged on both sides of the arc-shaped module unit at the same height. This application achieves control over the verticality of the interlocking piles by fabricating the template for the concrete guide wall of the interlocking piles. However, this structure requires extensive earthwork preparation before construction, resulting in a significant investment.

[0005] Existing case studies show that current technical solutions for controlling the verticality of interlocking piles in foundation pit support all focus on maintaining pile verticality during pile fabrication, without providing a vertical support structure after pile construction. Therefore, a structure is needed that can achieve vertical support for interlocking piles to improve construction safety, save construction materials, and shorten construction time.
