Problems solved by technology

[0004] The inventors found that most of the current pile foundations are equipped with reinforcement gauges, and when the reinforcement timing is lowered in the existing pile foundation, it is impossible to determine whether the reinforcement gauge is in the center of the drilling hole, and the reinforcement timing is mostly manually dragged, which may occur due to improper operation. Cause steel bar meter to fall into the drill hole and other problems, consume too much labor and waste construction time, increase the cost

Embodiment 1

[0034] In a typical implementation of the present disclosure, such as Figure 1-Figure 2 As shown, a positioning device for installing a steel bar gauge in an existing pile foundation borehole is proposed.

[0035] It mainly includes the disc 2 and the positioning block 3 matching the disc. The disc is provided with a plurality of chutes for cooperating with the positioning block. The chute is distributed along the radial direction of the disc. The positioning block slides with the chute, and the positioning block is adjusted. The distance from the center of the disc, the positioning block presses against the inner wall of the drill hole, and the positioning block moves to push the disc to move to achieve the purpose of adjusting the position of the disc;

[0036] The chute is at least three, and the chute is distributed in different positions of the disc, and the chute corresponds to the positioning block one by one. In this embodiment, three chute are taken as an example, as...

Embodiment 2

[0057] In another typical embodiment of the present disclosure, a working method of a positioning device for installing a steel bar meter in an existing pile foundation borehole as in Embodiment 1 is given.

[0058] Include the following steps:

[0059] After the steel bar meter and the steel bar are connected through thread fit, they go down to the borehole of the existing pile foundation;

[0060] Arrange the disk, move the disk along the installation groove until the steel bar meter is stuck at the end of the installation groove, and the steel bar meter and the disk are distributed coaxially;

[0061] Support the disc at the opening of the drilled hole, adjust the position of the positioning block, and push the disc to change its relative position with the drilled hole until the reinforcement meter, steel bar and drilled hole are coaxially distributed.

[0062] The borehole 7 is in the center of the existing pile foundation 5, the diameter of the borehole 7 can be adjusted...

Abstract

The invention provides a positioning device for installing a steel bar meter in an existing pile foundation drill hole and a working method of the positioning device, and relates to the field of pilefoundation monitoring. The positioning device comprises a disc, at least three sliding grooves formed in the radial direction of the disc and positioning blocks matched with the sliding grooves and sliding along the sliding grooves, and an installation groove penetrating through the disc in the axial direction is formed between every two adjacent sliding grooves; each installation groove extends to the center of the disc from the outer circumference of the disc, and the widths of the installation grooves are gradually reduced in the centripetal direction; and the disc is matched with the positioning blocks to form a centering structure, in cooperation with the installation grooves arranged in the disc, the disc and the steel bar meter are pushed by the positioning blocks to be arranged ina centering manner, the steel bar meter is matched with a steel bar to be installed on the disc, the steel bar meter is supported by the disc, and the effect of accurate centering installation of thesteel bar meter is achieved.

Description

technical field [0001] The disclosure relates to the field of pile foundation monitoring, in particular to a positioning device and a working method for installing a steel bar meter in an existing pile foundation borehole. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] The steel bar meter is often used to be buried in hydraulic structures or other concrete structures for a long time, to measure the steel bar stress inside the structure, and to simultaneously measure the temperature of the buried point. In the pile foundation static load test, by drilling holes in the existing pile foundation and lowering the steel bar gauge in the hole, the stress data of the steel bars at different steel bar meter positions can be obtained in the static load test. [0004] The inventors found that most of the current pile foundations are equipped with...
