Problems solved by technology

[0002] At present, in the construction process of municipal engineering, especially urban rail engineering, it is often necessary to insert steel pipe columns into super-long empty piles. There are many difficulties in the integrated construction of piles and columns, such as steel pipe column positioning, concrete pouring, and verticality control of steel pipe columns. Problems such as misalignment, elevation, and inclination often occur during column construction

Embodiment Construction

[0028] In order to further understand the content, characteristics and functions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] see figure 1 and figure 2 , the present invention improves the positioning device for inserting steel pipe columns into empty piles, including a bottom platform, a top platform, an alignment support 1, a steel pipe column elevating mechanism and an adjusting mechanism. The bottom platform, the top platform and the alignment support 1 form an integral platform, and the steel pipe column lifting mechanism is arranged in the integral platform.

[0030] Wherein, the bottom platform includes a bottom frame 2 and a second positioning hole plate 8, and a second positioning hole 9 larger than the diameter of the steel pipe column is cut out in the center of the second positioning hole plate 8. The bottom frame 2 is welded by 10# channel steel, the second posi...

Abstract

The invention relates to a positioning device for improving insertion of a steel pipe column into a hollow pile and a method for integrally constructing a pile column, and belongs to the technical field of steel pipe column construction by a cover digging reverse construction method, which mainly solves the problem of positioning the steel pipe column in an ultra-long hollow pile. The positioningdevice is characterized by comprising an integral platform comprising a bottom platform and a top platform, wherein a steel pipe column lifting mechanism is arranged in the integral platform; the bottom platform and the top platform are provided with coaxial steel pipe columns passing-through through holes; and an adjusting mechanism for adjusting a horizontal position of the steel pipe column isarranged on the bottom platform and / or the top platform. The positioning device for improving the insertion of the steel pipe column into the hollow pile and the method for integrally constructing thepile column have the advantages of ensuring that the steel pipe column in the ultra-long hollow pile is not displaced and offset, and are mainly used for integrally constructing the pile column.

Description

technical field [0001] The invention belongs to the technical field of construction of a steel pipe column by a cover-and-excavation method, and in particular relates to a precise positioning device for precisely fixing a steel pipe column on the ground to prevent its movement and deviation during the support construction of a steel pipe column by the cover-excavation method, and A method of integral construction of piles and columns. Background technique [0002] At present, in the construction process of municipal engineering, especially urban rail engineering, it is often necessary to insert steel pipe columns into super-long empty piles. There are many difficulties in the integrated construction of piles and columns, such as steel pipe column positioning, concrete pouring, and verticality control of steel pipe columns. Problems such as misalignment, elevation, and inclination often occur during column construction. Contents of the invention [0003] The purpose of the...
