Electronic mud specific gravity measuring device and measuring probe

Abstract

The invention discloses an electronic mud specific gravity measuring device and a measuring probe. The invention provides the device for measuring the specific gravity of the slurry by using the resistance strain gauges and related parts, when the device is immersed in the slurry to be measured, the device can output different electric signals, so that the specific gravity of the slurry can be measured through the change of the electric signals, and the device is not influenced by the depth of the device immersed in the slurry or the change of the specific gravity of the slurry. Therefore, during drilling cast-in-place pile hole forming and underground diaphragm wall grooving operation, the device is hung in a pile hole or an underground diaphragm wall groove section, the specific gravity of wall protection slurry at any depth and any position in the pile hole or the underground diaphragm wall groove section can be directly measured, operation is easy, convenient and rapid, sampling is not needed, and the device is convenient to operate and high in practicability. Therefore, rapid and accurate construction parameters can be provided for related construction processes.

Description

technical field [0001] The invention relates to the construction field of building foundation engineering, in particular to an electronic mud specific gravity measuring device and a measuring probe. Background technique [0002] In the field of building foundation engineering construction, many construction operations require the use of density measuring devices to measure the specific gravity of mud. For example, when drilling holes and clearing operations for bored piles, underground diaphragm wall grooves and groove cleaning operations, pile holes or grooves must be checked. The specific gravity of the retaining mud in the groove section of the underground diaphragm wall is measured, and relevant construction parameters such as the drilling speed of the drilling rig, the speed of the groove forming machine, and the concrete pouring time are adjusted in time according to the measurement results, so as to ensure that the quality of the construction process meets the requirem...

Problems solved by technology

For the deep mud inside the bored pile pile hole or inside the underground diaphragm wall groove section, when the mud specific gravity scale method, measuring cylinder or measuring cup and weighing balance method are used for measurement, the extraction method of the mud sample has a great influence on the measurement results. Accuracy has a high impact and the Baume hydrometer method cannot be used for internal measurements in deeper mud

In addition, when using the mud specific gravity scale method, measuring cylinder or measuring cup and weighing balance combination method to measure the mud specific gravity, the sampling and measurement process is relatively cumbersome, and each measurement can only measure the mud specific gravity data at the depth of a certain sampling point, which cannot be continuous Measure mud specific gravity data within a certain depth range

[0004] There are many newer and improved mud measurement techniques. For example, the Chinese patent document with application number 202021480049.9 reports an electronic mud hydrometer. This document conducts a simple study on the overall structure of the electronic mud hydrometer. The electronic mud hydrometer is composed of a density sensor, a functional main board, a connecting cable and a wire reel, but this document does not describe the detailed structure and realization of each functional component of the electronic mud hydrometer, especially the key core component, the density sensor. in-depth study of the principles
