Problems solved by technology

[0003] In the prior art, the inclinometer tube is generally inserted into the existing drill core hole first, and then a separate inclinometer is placed into the inclinometer tube for measurement. The problems with this method include that the buried inclinometer tube is generally made of metal , not easy to elastically deform and bend, there may be a problem that it cannot continue to be lowered in the section where the slope of the core hole changes significantly; What is actually measured in the process is the inclination of the inclinometer pipe, which is different from the actual inclination of the core hole, and a single inclinometer can only obtain the inclination of a specific position, and cannot obtain the inclinations of different positions at the same time, so the efficiency is low. And requires manual operation, time-consuming and labor-intensive

Embodiment Construction

[0033] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0034] Such as figure 1 with figure 2 As shown, this embodiment discloses a device for measuring the slope of a core hole, including:

[0035] The inclinometer tube 1 is arranged in the core hole 51 of the foundation pile 5 to be measured, and is used for installing the inclinometer; the inclinometer tube is a waterproof material with a certain degree of flexibility;

[0036] n groups of inclinometers 2 are installed on the inner wall of the lumen of the inclinometer tube 1 and arranged at intervals along the extension direction, and each set of inclinometers 2 is used to detect the inclination information of a section in the lumen of the inclinometer tube; each s...

Abstract

The invention discloses a drilled core hole slope measuring device. An operator descends a slope measuring tube into a drilled core hole which is about to be measured, multiple inclinometers arrangedin the slope measuring tube can simultaneously acquire inclination degrees of different depths in the drilled core hole, the drilled core hole slope measuring device is convenient to operate, the shortcoming that in the prior art, the inclination degrees only can be acquired repeatedly is avoided, the measurement time is saved, and meanwhile, comprehensive and multi-dimensional inclination information of the drilled core hole is acquired so as to facilitate follow-up analysis operation on the quality of a foundation pile.

Description

technical field [0001] The invention relates to the field of foundation pile monitoring, in particular to a device for measuring the slope of a cored hole. Background technique [0002] When the core-drilling method is used to detect foundation piles, due to some reasons, the boreholes cannot reach the bottom of the pile, but deviate from the pile body, so that the construction quality of the foundation pile cannot be effectively evaluated. The reason, on the one hand, may be that the drilling slope of the inspection unit exceeds the specification requirements during coring; on the other hand, it may be that the construction unit’s improper construction causes the slope of the engineering pile to exceed the allowable value of the specification. In order to accurately determine the cause of the accident and clarify the responsibility for the accident, it is particularly important to use reasonable and effective measuring devices and methods to accurately measure the slope of ...
