Abstract

The invention discloses a casing piece and a bored pile, wherein, the casing piece includes at least two splicing plates and a connecting structure, and at least two splicing plates are sequentially connected end-to-end through the connecting structure to form an enclosure perfusion hole. The casing part of the present invention can be assembled by splicing at least two splicing plates. After the concrete pouring is completed, at least two splicing plates can be taken out in order to reduce the friction with the soil. Compared with the existing The one-piece cannula in the state-of-the-art is easier to remove.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a casing piece and a bored cast-in-place pile. Background technique [0002] When constructing bored piles with manual or mechanical equipment, in order to prevent the hole from collapsing due to too loose soil, casing is often used to support the hole wall, and the casing can be taken out after pouring concrete for repeated use. . However, due to the excessive friction between the traditional integral casing and the soil, it is easy to cause the casing to be unable to be easily removed. [0003] In view of this, it is necessary to provide a casing member and a bored cast-in-place pile to at least overcome or alleviate the above-mentioned defects in the prior art. SUMMARY OF THE INVENTION [0004] The main purpose of the present invention is to provide a casing piece and a bored cast-in-place pile, which aims to solve the technical problem that the existing i...
