Abstract
The invention discloses a suspension measuring method for the internal displacement of post and a relative device, comprising a protective tube (2) in which a connector (4) is arranged, wherein the measuring device comprises a fixed block (6) and a flexible line (5), while one end of the flexible line (5) is arranged with a fixing device (3) in the connector (4), and another end is arranged with a weight (7), the flexible line (5) is coiled on the fixed block (6). The invention arranges the connector in the protective tube, uses the flexible line to slowly arrange the fixing device at the end of the flexible line into the protective tube, and fixes the fixing device on the connector, with the advantages in the internal displacement measurement of post longer than 50m.
Description
Technical field
The present invention relates to a kind of method for measurement and device thereof of stake inner displacement, relate in particular to a kind of suspended measuring method and device thereof of stake inner displacement.
Background technology
It all is at measured displacement place ornaments rigid rod that at present domestic and international stake inner displacement measures, and rigid rod is extended the place, ground, lays displacement transducer in masthead portion and carries out the displacement measurement.This method has been widely used since using always.But along with drilled pile is more and more longer, length even surpass 100m sometimes, this method of stake begins to show its defective, rigid rod causes existing tangible distortion phenomenon owing to various reasons have buckling phenomenon in the displacement transmittance process.External improving one's methods at present is to adopt the rigid rod method of delivering in relays, and thinks that the rigid rod transmission should control length about 20m, promptly about every section long 20m of rigid rod, measures this section with sensor and moves and be passed to ground, is total displacement with multistage is displacement superposed.Obviously, because method is intrinsic, every section displacement counts the influence of sensor error in measurement, and the transmission of multistage overlay error is bigger; Its technology relative complex in addition, Master Cost is higher, therefore, improves to some extent though the more traditional stake inner displacement of this method of testing measures, and uses lessly at home, still adopts one section traditional rigid rod method of testing.
Summary of the invention
The invention provides a kind of suspended measuring method and device thereof that can improve the stake inner displacement of ultra-long pile stake inner displacement measurement accuracy.
The present invention adopts following technical scheme:
A kind of suspended measuring method of stake inner displacement, this method may further comprise the steps:
1. piecing devices are set in pillar,
2. pillar is embedded in the stake,
3. the end in flexible wires is provided with fixer, and this fixer is put into pillar, makes fixer be fixed on the piecing devices,
4. the other end of flexible wires is walked around fixed pulley, and weight is set at this end,
5. stake is applied acting force,
6. measure the displacement of flexible wires.
The suspended measuring device of stake inner displacement comprises pillar, is provided with piecing devices in pillar, and this measuring equipment comprises fixed pulley and flexible wires, is provided with fixer at an end of flexible wires, and the other end is provided with weight, and flexible wires is on fixed pulley.
Compared with prior art, the present invention has the following advantages:
1, measurement accuracy height of the present invention.It all is at measured displacement place ornaments rigid rod that at present domestic and international stake inner displacement measures, and rigid rod is extended the place, ground, lays displacement transducer in masthead portion and carries out the displacement measurement.This method has been widely used since using always, but along with drilled pile is more and more longer, sometimes length even surpass 100m, this method of stake begins to show its defective, rigid rod is owing to various reasons have buckling phenomenon, cause in the displacement transmittance process, existing tangible distortion phenomenon, be difficult to guarantee measurement accuracy, the present invention is then by being provided with piecing devices in pillar, the fixer that will be located at this flexible wires end by flexible wires is slowly put into pillar, make fixer be fixed on the piecing devices at last, make dark stake such as fixer and its grade that identical distortion be arranged, the other end with flexible wires is provided with weight again, on fixed pulley, has guaranteed that the part of flexible wires in pillar always is in straight configuration, can not produce buckling phenomenon, thereby guaranteed the precision that measures, especially when measurement in the stake inner displacement of 50m was grown up in the i.e. stake of ultra-long pile, this advantage was more outstanding.
2, the present invention can reduce cost.
Traditional rigidity method for measurement is when measuring ultra-long pile, be difficult to guarantee the precision that measures, external improving one's methods at present is to adopt the rigid rod method of delivering in relays, think that the rigid rod transmission should control length about 20m, be about every section long 20m of rigid rod, measuring this section with sensor moves and is passed to ground, be total displacement with multistage is displacement superposed, obviously, its technology relative complex, Master Cost is higher, and the used device of the present invention is simple, after test finished, measuring equipment can reclaim, and had reduced the measurement cost when the ultra-long pile internal displacement measured.
