Description
Technical field
The utility model belongs to the technical field of rock-soil engineering in-situ test, and in particular to a kind of soil pressure cell fixed installation
Structure.
Background technique
With the continuous promotion that China's economic status develops on a large scale in production globalization, ultra-large type hypogee, deep-sea immersed tube
The construction such as tunnel, the interaction of structure and soil layer are most important for the applicability and reliability of assay structure.
Cloth in situ is generallyd use in geotechnical engineering field monitoring field in order to measure the soil pressure acted on structures
If soil pressure cell measures the soil pressure acted on different directions, soil pressure cell generally transmits electricity by backboard, tablet, signal
The composition such as cable, vibratory string and exciting electromagnetic coil.
The interfacial type of soil pressure cell is installed frequently with pre-buried mode in advance at present, i.e., will be native by the method for binding or welding
Pressure cell is connected with structure reinforcing bars, to be fixed in concrete structural surface.But interface is easily led to using such mode
Inbuilt soil pressure cell " survival rate " is lower, the deformation of the more difficult true reflection large-sized concrete structure of monitoring the data obtained and stress
Dynamic process.By the induction and conclusion to engineering before, the shortcoming that tradition shifts to an earlier date pre-buried mode is mainly shown as following
Three aspects：
(1) construction of soil pressure cell interfacial type installation takes a long time.Tradition shifts to an earlier date in pre-buried mode, soil pressure cell itself nothing
It need to be connected using binding or welding with structure reinforcing bars, and be adjusted in real time according to thickness of concrete cover simultaneously by fixed device
Whole installation site, therefore an embedded soil pressure cell takes a long time.Complicated structures are needed to test number
According to more, then inbuilt soil pressure cell is just more, the time for needing to delay influences construction speed with regard to more.
(2) reliability of soil pressure cell interfacial type installation is lower.Tradition shifts to an earlier date in pre-buried mode, and soil pressure cell is embedded to be finished
After be difficult to adjust its installation site.Formwork hoisting, concreting and the work progress such as vibrate are likely to cause soil pressure cell
The offset or torsion of original installation site, deviateing gained monitoring data, original sets box position or soil pressure cell is embedded in concrete guarantor
Lost in sheath interface soil pressure monitoring effect, therefore tradition shift to an earlier date pre-buried mode in soil pressure cell interfacial type installation it is reliable
Property is lower.
(3) precision of soil pressure cell monitoring data is poor.Tradition shifts to an earlier date in pre-buried mode, past after soil pressure cell is embedded
It is flushed with concrete structural surface toward being difficult to keep soil pressure cell surface, makes between the two that there are biggish gaps, therefore poured
Soil pressure cell surface is easily led in work progress and covers one layer of thicker concrete, and gained monitoring data fail really to reflect boundary
The stress condition of face soil pressure keeps the precision of monitoring data and reliability poor.
Therefore, the interfacial type mounting device of soil pressure cell a kind of is developed for the feasibility of new concrete structure and practical
Journal of Sex Research is very necessary.
