Problems solved by technology

[0004] The technical problems to be solved by the present invention are: 1. To overcome the existing technical defects, a telescopic settlement and inclinometer tube for measuring settlement and horizontal displacement is provided. The tube can adapt to the deformation of the soil without damage when the soil undergoes a large deformation, and has the characteristics of quick and simple installation; 2. It can prevent foreign substances such as sediment and water from entering the settlement tube and the inclinometer tube

Embodiment Construction

[0025] In order to make the purpose, technical solution and advantages of the present invention clearer, the method of the present invention will be further described in detail below in conjunction with the accompanying drawings and Embodiment 1. The specific implementation cases described here are only used to explain the present invention, not to limit the present invention.

[0026] refer to figure 1 , figure 2 : After the drilling at the position where layered displacement and deformation measurement is required is ready, install the bottom cover at the bottom of the subsidence and inclinometer measuring tube 1, and put it into the drilled hole. When the nozzle of the measuring tube is about 50cm away from the orifice, fix the settlement and inclinometer measuring tube 1 outside the hole with a temporary fixture so that the settlement and inclinometer measuring tube 1 cannot move up and down freely in the hole. Install and fix the free expansion joint tube 2 on the sett...

Abstract

An extensible settlement and incline measuring pipe for measuring settlement and horizontal displacement is composed of a settlement measuring pipe, an incline measuring pipe, a bottom cover and a joint pipe and is characterized in that the joint pipe is an freely-extensible connection sleeve pipe which is composed of two secondary pipes and a main pipe, the external walls of the two secondary pipes are provided with sliding grooves, and fixing pins arranged on the internal wall of the main pipe are snapped with the sliding grooves of the secondary pipes; and both ends of each secondary pipe are respectively connected with the screws of the settlement measuring pipe and the incline measuring pipe through locating pins. The extensible settlement and inline measuring pipe for measuring the settlement and the horizontal displacement can guarantee the settlement measuring pipe and the inline measuring pipe not to be deformed along with a large-displacement deformation of a soil body, thereby reducing the interaction force between the settlement measuring pipe of the inline measuring pipe and the surrounding soil body and reducing the probability of pipe blocking or pipe breaking; sediment and water can be effectively prevented from entering among every parts; and the freely-extensible joint pipe, the settlement measuring pipe and the incline measuring pipe can be mounted through direct screwing. Therefore, the extensible settlement and inline measuring pipe for measuring the settlement and the horizontal displacement is convenient to build in and mount, has low technical requirements for mounting personnel, can largely reduce the mounting time, and is easy to process and achieve.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering safety monitoring; in particular, it relates to a telescopic settlement and inclinometer tube for measuring settlement and horizontal displacement, which is used to monitor the settlement and horizontal displacement of different parts of foundations and geotechnical buildings. Inclinometer tube. The invention also relates to the installation method of the telescopic settlement and inclinometer pipe for measuring settlement and horizontal displacement. Background technique [0002] The engineering safety monitoring specification requires that during the construction period or the operation period, the stability of the foundation or the internal stability of the geotechnical structure should be monitored, analyzed and judged, and countermeasures should be taken. It is usually used to install and bury settlement tubes and inclinometer tubes; put a closed magnetic ring on the settlem...
