Description
Technical field
The present invention relates to a kind of circular test pile preparation method of assembled, more particularly to a kind of circle of live quick assembling
The preparation method of test pile and pile body.
Background technology
The characteristics of traditional experiment stake：
(1) when pile body is prefabricated, together with tester is prefabricated with pile foundation, then squeeze into ground.Its shortcoming exists
Prestressing force is produced to tester in the setting and hardening and maintenance processes of 1. concrete and temperature effect is acted on, this can be in certain journey
Cause tester misalignment or failure on degree；2. during pile foundation construction, pre-buried tester receives construction power inside pile foundation
Act on (static pressure, impact, shock etc.), it is most likely that destruction instrument；3. tester makes and installed two processes by pile foundation
Afterwards, its precision and accuracy are necessarily significantly influenceed, and the extent of damage of each tester can not be now weighed,
Measurement result is difficult to ensure, is brought to engineering and much test hidden danger.
(2) when pile body is cast-in-place, tester welds together with steel reinforcement cage in advance, is then inserted into cast-in-place hole,
Placing concrete in hole, forms pile body.Its shortcoming is that the precision of the 1. installation site of tester is relatively low；2. tester
Perpendicularity or levelness are difficult to ensure card；3. the setting and hardening and maintenance processes of concrete are produced to tester prestressing force and temperature
Effect is difficult to estimate, and the degree of accuracy of measurement and reliability are difficult to hold；4. damage of the tester in the construction work of pile foundation
Degree can not be tested and counted, and measurement result is difficult to ensure, also bring many test hidden danger to engineering.
To sum up, the subject matter of traditional experiment stake presence is：1. the installation quality of measuring instrument be difficult to ensure that, 2. pile body
The extent of damage brought to tester of constructing is difficult to estimate, 3. there is more engineering test hidden danger.
Therefore, need badly at present seek it is a kind of can guarantee that instrument install and pile body construction quality can guarantee that tester again
Accuracy of measurement, the test pile of live quick assembling pile body and preparation method seem particularly significant.
