Description
Technical field
The utility model relates to be related to static-loading test ballast when a kind of civil engineering groundwork and pile detection
The device that counter-force uses, especially a kind of civil engineering monoblock type static test heap carrying platform.
Background technique
Static-loading test ballast counter-force is mainly from 1, anchorage pile, anchor pole at present；2, artificial preloading；3, examination is utilized
Test the frictional resistance (self-balancing load box) of stake itself.But since site condition limits, anchorage pile or anchor pole cannot construct, self-balancing
Load box is also due to pile body frictional resistance is far smaller than the reasons such as bottom bearing, using being also restricted.Artificially preloading is basic again for face pressure
On do not influenced by site condition and pile body itself frictional resistance and bottom bearing ratio, adopted extensively in static-loading test
With.
Earliest artificial preloading is that manually sand pocket is carried on the back to pile on heap carrying platform, and present heap loading is moved mainly by hanging
Vehicle is completed, and pile is manually only completed.Artificially face pressure weight heap support method be: first centered on testing site construct girder buttress and time
Beam buttress, girder buttress is shorter than secondary beam buttress, and then girder is placed on girder buttress, then above girder with girder Vertical Square
Be placed on secondary beam buttress to secondary beam, girder with 20 millimeters of secondary beam vertical range or so, girder cannot contact compression, preloading with secondary
When girder buttress be not subject to top preloading loading be solely subjected to girder self weight.
The disadvantage is that adjust the height difference of girder buttress Yu secondary beam buttress, it is ensured that secondary beam is not pressed directly after the installation of primary and secondary beam
To girder, the right angle setting distance between girder and jack is not influenced.After being installed, between girder, secondary beam and secondary beam with
It is not connected with each other between secondary beam, is in granular media state, whole stress is poor, high when causing preloading if secondary beam buttress is uneven
Secondary beam elder generation stress, and low secondary beam elder generation stress when girder work rises be easy to cause secondary beam deformation excessive or even failure.
Secondary beam radical is more, repeatedly lifting, easily generation safety accident is needed when installation, and installation speed is slow.Each project
Each testing site will constantly repeat this process.Transporting and hoisting is inconvenient after detection, and stock management is also inconvenient.
It easily occurs under fixed load, is mostly used secondary beam radical or few phenomenon that happens occasionally with secondary beam radical, although
Multi-purpose secondary beam radical does not have serious consequence, but causes secondary beam deformation serious with secondary beam radical consequence less serious case less, and mechanical property becomes
Difference, consequence serious person is few to be influenced testing result with secondary beam radical platform cisco unity malfunction and causes safety accident.
In addition, being not fixed forming between secondary beam, the space between secondary beam can not be efficiently used.
If differential settlement occurs for platform ground, platform is easily tilted, and the test platform built is granular media formula structure, is not had
Method can adjust the balance of platform, in addition to being removed, can only just be allowed to tilt.In the case where failing to remove in time, if
Platform quick slant, heap, which is loaded in the load on platform and must will cause, to collapse, so that safety accident occur.And for vertical compression
The ballast load of static test institute preloading, usually tens tons, several hundred tons to kiloton or even a few kiloton rank.Weight is quite frightened
People, once safety accident occurs, consequence is extremely serious.
Each testing site of one project is both needed to even carry out the transfer of static load device, field with transport vehicle sometimes with crane
Interior easy fugitive dust, although the rainy day in this way, fugitive dust was not easy miriness in field to take on over-the-counter road again, crane transport vehicle exhaust emissions
Also air is polluted.
Loading heap carrying platform is always that formula is taken in granular media spelling for a long time in a word, and heap carrying platform does not form standardization, series
Change, to build the extensive backwardness of mode original, be unfavorable for the development of civil engineering dead-load detection.Dead-load detection developing water Pingyuan County is low at present
In the development of foundation basic construction technology, platform decades ago and preloading mode in addition to crane replace workers carry's ballast it
Outside, static load device and heap support method there is no big variation, development.
Therefore, preloading device existing defects used by existing static-loading test, need to improve.
