Problems solved by technology

Such a large-scale ultra-deep foundation pit is constructed by the upside-down method. The column pile vertical adjustment technology used in the upside-down method construction technology in the past is no longer suitable for the vertical adjustment of the ultra-deep column piles in this project. It is necessary to invent an ultra-deep upside-down method. Intelligent vertical adjustment device to ensure the construction accuracy of column pile construction in deep reverse method

Embodiment Construction

[0011] In order to better understand the technical content of the present invention, specific embodiments are given together with the attached drawings for description as follows.

[0012] figure 1 Shown is the structural schematic diagram of the intelligent vertical adjustment device for ultra-deep upright piles proposed by the present invention. Such as figure 1 As shown, the embodiment of the intelligent vertical adjustment device for ultra-deep upside-down piles proposed by the present invention includes the following structures.

[0013] The detachable tool-type steel pipe 104 is used as an inclinometer to dock with the ultra-deep steel column 106 axis. The top fixing device fixes the detachable tool type steel pipe 104 on the ground at the designed position. In the embodiment of the present invention, the top fixing device is composed of a positioning sleeve 105 and a hydraulic support device 107 arranged under the positioning sleeve 105 to play a supporting role. As...

Abstract

The invention provides intelligent verticality adjusting method and device of an ultra-deep topdown construction method stand column pile, which intelligently adjust the verticality of the ultra-deep topdown construction method stand column pile so that topdown construction method construction in ultra-deep underground space is more accurate and convenient in the intelligent verticality adjustment of the stand column pile. The verticality adjusting device of the ultra-deep topdown construction method stand column pile comprises a detachable inclination measuring device, a top fixing device, a connecting rod adjusting expander, a sensor and a high-precision verticality detection computer device, wherein the detachable inclination measuring device is in butt joint with the axle center of the stand column; the top fixing device is fixed with the detachable inclination measuring devices; the connecting rod adjusting expander acts on the outer wall of the stand column to adjust the verticality of the stand column; the sensor is arranged on the detachable inclination measuring device to sense the verticality of the detachable inclination measuring device and send verticality sensing information; and the high-precision verticality detection computer device is used for receiving the verticality sensing information sent by the sensor and starting the connecting rod adjusting expander to adjust the verticality of the stand column according to the verticality sensing information.

Description

technical field [0001] The present invention relates to a vertical adjustment method and device for a vertical pile, and in particular to an intelligent vertical adjustment method and device for an ultra-deep upside-down vertical pile. Background technique [0002] The upside-down method is a new foundation pit support technology developed in recent years. It is an effective method for constructing multi-storey basements of high-rise buildings and other multi-storey underground structures. [0003] The intermediate column in the upside-down method construction process is a temporary structural member that replaces the engineering structural column during the upside-down method construction process. It mainly supports the completed main structure and construction load. After the construction of the underground structure is completed, the support and row columns are generally outsourced with concrete as the permanent structural support columns of the basement. Therefore, the...
