Embodiment Construction

[0006] First, a round tube 1 with a closed bottom is placed inside the cylinder 3, and a measurement reference point is built in the center of the bottom of the round tube 1. A laser pointer 2 can be selected, and the laser pointer 2 is placed upward so that the laser beam follows the center line of the round tube 1. Injection, place the centerline of the round pipe 1 on the centerline of the rigid steel column 3 on the ground, and fix it with the rigid steel column 3 with a fixed bracket 6, so that it can be pulled out after the construction is completed, and the next column will be corrected use. Set the fixed frame 4 on the ground in advance, and mark the theoretical axis position of the corresponding pile foundation and mark the reference point of the theoretical axis position of the pile foundation on the fixed frame 4, put the rigid steel column 3 into the pile body 5 and place it The center of its top is adjusted on the theoretical axis position of the corresponding pil...

Abstract

The invention relates to a method for measuring the verticality of a cylinder in a pile directly during underground engineering one-cylinder-one-pile construction, which is characterized in that a circular tube of which the bottom is sealed is arranged inside the cylinder; the inside of the center of the bottom of the circular tube is provided with a measuring reference point which is distributive light; and the distributive light is a laser beam. On the ground, a center line of the circular tube is positioned on a center line in a stiff steel cylinder, and the circular tube is relatively fixed with the stiff steel cylinder; a theoretical axis position and a reference point of a corresponding pile foundation are marked on the ground in advanced, and after the stiff steel cylinder is put in the cylinder, the top center of the stiff steel cylinder is adjusted and fixed to the theoretical axis position of the corresponding pile foundation; then a vertical collimator is used so as to enable the center of the vertical collimator to align with the reference point on a ground axis; and if a benchmark axis and the measuring reference point of the stiff steel cylinder are positioned on thesame straight line, the stiff steel cylinder lies in a vertical state. The method has the advantage of having direct and quick characteristics, measures objects directly, reflects the verticality of the objects, can be used circularly and has economic and high-saving characteristics.

Description

technical field [0001] The invention relates to a method for directly measuring the verticality of a column in a pile during the construction of one column and one pile in underground engineering. Background technique [0002] The reverse construction method is to first construct the underground diaphragm wall or other supporting structures along the axis of the basement of the building or around it, and at the same time construct the supporting piles at relevant positions inside the building and use them as construction period or as a permanent structure) to bear the self-weight of the superstructure and construction load support. When it is completed, the beam-slab floor structure on the ground floor is used as the support of the underground diaphragm wall with high rigidity, and then the earthwork is excavated layer by layer and the underground structure of each layer is poured until the bottom plate is sealed. Since the floor structure of the ground floor has been const...
