An underwater inclinometer pipe direction limiter

Abstract

An underwater inclinometer direction limiter comprises a top turning device, a middle connection rod device and a bottom fixing device; the top turning device is formed by a cross rod and a short connection rod; the middle connection rod device is provided with long connection rods, and two or more long connection rods can be arranged according to the embedding depth of an inclinometer; the bottom fixing device is formed by a bottom probe and a limiting screw rod; the top turning device and the middle connection rod device are fixedly connected; the middle connection rod device has a fixed connection mode and is fixedly connected with the base fixing device. The direction of the inclinometer can be corrected anytime in the embedding process of the inclinometer, so the embedding quality of the inclinometer is improved, and the accuracy of data observation of a fixed clinometer is ensured; the defects of high investment cost and work period postponement caused by the failed embedding of the traditional fixed clinometer are avoided, and the embedding cost is greatly reduced; the operation is simple and convenient, the limiter can be repetitively used, personnel and procedures are reduced and the embedding burying efficiency is improved.

Description

Technical field [0001] The invention relates to a limit tool for controlling the buried quality of an inclinometer tube in the field of deep horizontal displacement monitoring, in particular to an inclinometer tube burying process in a water area, which is used to test the positive direction of an underwater inclinometer tube Accurately controlled underwater inclinometer direction limiter. Background technique [0002] The inclinometer tube is widely used in the field of measuring the deep horizontal displacement of the soft soil foundation of the reclamation project. There are two pairs of perpendicular guide grooves for the orientation of the inclinometer probe in the measuring tube. The direction of the guide groove must be strictly controlled during the embedding process , So as to ensure the accuracy of the observation results, otherwise it will lead to failure of burying. Therefore, the direction control of the inclinometer tube is the most critical process in the process ...

AI Technical Summary

Problems solved by technology

During the installation and burial of the inclinometer pipe, the whole inclinometer pipe is put into the water from above the water, and the direction of the guide groove of the inclinometer pipe is difficult to accurately control, which seriously affects the embedding quality of the fixed inclinometer, thereby affecting the accuracy of observation data

At the same time, fixed inclinometers are expensive, and failure to bury them will result in high costs and even affect the progress of the project

At present, the buried underwater inclinometer pipe adopts the method of artificial diving to the painted orifice for small-scale adjustment, which is expensive and the adjustment direction is not ideal.
