Abstract
The utility model discloses a pile body internal displacement suspension measuring device which comprises a protective pipe (2), a joint device (4) arranged in the protective pipe (2), a fixed pulley (6) and a flexible wire (5). One end of the flexible wire (5) is provided with a fixing instrument (3) which is placed in the joint device (4) of the protective pipe (2). The other end of the flexible wire is provided with a weight drop (7). The flexible wire (5) is wound on the fixed pulley (6). Through the joint device in the protective pipe and through the flexible wire that slowly places the fixing instrument arranged at the end part of the flexible wire into the protective pipe, the fixing instrument is fixed on the joint device. The advantages of the utility model are more outstanding in the pile body internal displacement measuring of super-long piles with a length more than 50m.
Description
Technical field
The utility model relates to a kind of measuring equipment of stake inner displacement, relates in particular to a kind of suspended measuring device 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 utility model provides a kind of suspended measuring device that can improve the stake inner displacement of ultra-long pile stake inner displacement measurement accuracy.
The utility model adopts following technical scheme:
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 utlity model has following advantage:
1, the utility model measurement accuracy height.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 utility model 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 utility model 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 utility model is simple, after test finished, measuring equipment can reclaim, and had reduced the measurement cost when the ultra-long pile internal displacement measured.
