Abstract

The invention relates to a positioning device and method for a steel protective canister in pile foundation construction. The positioning device comprises a positioning shaft, a length-adjustable adjusting rod, and a container body. The positioning shaft is arranged at the pile foundation arranged position and located in the center of a pile foundation. The length of the adjusting rod is adjusted to enable the length of the adjusting rod to be equal to the radius of the steel protective canister. The first end of the adjusting rod is rotationally connected to the positioning shaft. The container body is fixed to the second end opposite to the first end of the adjusting rod. A marking material is contained in the container body. The bottom of the container body is provided with a through hole through which the marking material is leaked. The adjusting rod is rotated around the positioning shaft so as to drive the container body to rotate together, and the position of the steel protective canister is positioned on the periphery of the positioning shaft through the leaked marking material. The track marked by the marking material is clear, and the positioning device and method are capable of achieving accurate positioning and being used in a circulation mode, and applicable to steel protective canisters with different sizes.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a positioning device and a positioning method for a steel casing in pile foundation construction. Background technique [0002] In the pile foundation construction, it is necessary to excavate the hole piles. During the excavation of the hole piles, it is necessary to set up a retaining wall to protect the hole piles, prevent the holes from collapsing, and avoid affecting the construction progress and safety. Due to the instability of the soil, it is difficult to construct the reinforced concrete retaining wall, so the steel casing is used to protect the hole piles. The steel casing can stabilize the hole wall, prevent the hole from collapsing, isolate the surface water, guide the drill bit, fix the pile position, protect the original ground during operation, etc. The steel casing is a circular barrel that is hooped with iron sheets according to the size of the hole pile and...
