A Fixing Device for Vertically Arranging Earth Pressure Cells

Abstract

The invention discloses a fixing device of a vertically arranged soil pressure cell, and is used for fixing the soil pressure cell in roadbed engineering monitoring. The fixing device consists of a main body part (1), a top restraining part (2) and a fixing part (3), wherein the stability of the lower end part of the main body part is maintained through a support plate (102) and rectangular steel (104), the deformation of the main body plate (101) is reduced through restraining angle steel (103), restraining force provided by the fixing part (3) is exerted on the end part by the upper end part through the top restraining part (2), and the stabilizing effect is achieved. When the fixing device of the vertically arranged soil pressure cell is adopted, a relative fixed body can be effectively provided, so the soil pressure cell can perfectly realize the effects, and various problems in vertical soil pressure cell burying in the roadbed monitoring are solved. The fixing device has the advantages that the manufacturing is simple, the cost is low, and the installation is convenient. According to on-site actual measured values, the value measurement of the soil pressure cell installed by using the set of device is accurate, the design of the device is reasonable, and the fixing device can be popularized and used in relevant engineering.

Description

technical field [0001] The invention relates to the field of subgrade engineering monitoring equipment manufacturing, more precisely, it is a fixing device for vertically arranged earth pressure cells, which provides a relatively fixed surface for the vertically arranged earth pressure cells to prevent them from colliding with soil deformation. Move to more accurately test the horizontal stress variation of the soil. Background technique [0002] The earth pressure cell is a common device used to test soil stress on site, and is widely used in rock mass engineering fields such as slopes, roadbeds, and foundation pits. Its own development has gradually matured. At present, the most commonly used vibrating wire sensor has the advantages of high sensitivity, high precision, good stability, and relatively cheap price. It is buried in retaining walls, anti-slide piles, earth embankments, buildings, etc. Long-term testing of internal stress changes can be carried out in soils suc...

Problems solved by technology

Some researchers generally use auxiliary piles or special fixing equipment for earth pressure cells on natural slopes to fix and install earth pressure cells. Although this method is feasible, for high embankments, pouring auxiliary piles is not only costly and time-consuming , will also affect the site construction; if some special fixed equipment used in natural slopes is used to install the earth pressure box, it often needs to wait until the subgrade construction is completed, and the hole needs to be re-drilled, which is very troublesome
