Abstract

The utility model discloses a foundation pile center point positioning rechecking device which comprises a bearing, wherein sliding grooves with upper openings are fixed on the outer periphery of the bearing at equal intervals, adjusting positioning rods are embedded in the sliding grooves, and a baffle block used for clamping the outer side of a foundation pile is arranged at the end part of the other end of each adjusting positioning rod. The utility model can solve the problem that the circle center of the site survey foundation pile can not be accurately positioned and rechecked, and is convenient to carry and operate.

Description

Foundation pile center point positioning rechecking device

Technical Field

The utility model relates to the field of buildings, in particular to a foundation pile center point positioning rechecking device.

Background

At present, a coordinate positioning method is generally adopted for pile foundation construction positioning, a total station is used for axis guiding measurement, so that the accuracy of pile center positioning is ensured, 4 directional control points are led out from the pile center for checking the center point position of the pile foundation in the construction process, the pile position is checked at any time in the construction process, and the accuracy of the pile position is maintained.

However, the method for rechecking the pile position has higher requirements on control points and is complex to operate, and if one of the control points deviates, the whole positioning precision and accuracy can be affected.

Disclosure of Invention

The utility model aims to overcome the defects of the prior art and provide the foundation pile center point positioning and rechecking device which can solve the problem that the site survey circle center cannot be accurately positioned and rechecked and is convenient to carry and operate.

In order to achieve the above purpose, the utility model is realized by the following technical scheme:

the utility model provides a foundation pile central point location recheck device comprises the device body, the device body includes the bearing, the equidistant spout that is fixed with upper portion opening of outer periphery of bearing, the embedding has the regulation locating lever in the spout, the tip of the other end of regulation locating lever is provided with the stop that is used for the card to set up the stake foundation outside.

And a GPS rod for reading the coordinate parameters of the center point of the pile is inserted into the middle hole of the bearing.

The rod body of the adjusting and positioning rod is formed by a telescopic structure.

The rod body of the adjusting and positioning rod is provided with scales.

The distance between the sliding grooves is 1/3 of the outer circumference of the bearing.

The bearing is composed of a rolling bearing with an inner diameter of 20 mm.

Compared with the prior art, the utility model has the following beneficial effects:

the positioning rod adopts a telescopic structure with adjustable length, can be flexibly adjusted according to the diameter of the on-site pile, and is suitable for piles with different diameters; the sliding groove arranged on the outer side of the bearing can embed the positioning rod therein, and the positioning rod can be quickly disassembled after construction is finished, so that the positioning rod reduces the volume of the positioning rod and is easy to carry; the GPS rod can be placed in the hole in the middle of the bearing, the coordinate parameters of the central point can be read quickly in construction, the assistance of other tools is not needed, a large number of paying-off fixed-point works are reduced, the working efficiency of pile position rechecking is improved, and the problem that the site survey circle center cannot be positioned and rechecked accurately is solved effectively and quickly.
