Technical field
The utility model relates to the foundation bearing capacities of civil engineering to detect test field, and in particular to Yi Zhongjing
Carry settlement observer.
Background technique
The static load test of foundation bearing capacity test is the important tests of building foundation test of bearing capacity, number
According to reliable and validity be directly related to building safety quality.The settlement measurement method of traditional foundation basis static test be
Displacement sensor is fixed on the datum line beam of an erected on site, the gauge head of displacement sensor is extended on pile foundation measuring point,
To sedimentation deformation of the relative displacement as pile foundation between measuring basis beam and measuring point.This measurement method does not consider base
The erection problem of quasi- beam.Since datum line beam is usually the steel I-beam of about 5~10 meters of a root long degree, limited length can only frame
Near measured point.Since static load test needs tens tons of counter-forces for arriving kiloton, these counter-forces are usually by banking up on site
Big field mass provide.Thus it leads to the problem of a new big field mass and banks up region itself and also generated by weight and sink
Drop, these subsiding belt moving frames are set to datum line beam above and settle together.Therefore the sedimentation that practical static load test measures is opposite
In the sedimentation of datum line beam, rather than absolute sedimentation value.In addition, the variation of the morning and evening temperature difference can also make when girder steel length is too long
Deformation occurs for girder steel, and sedimentation is caused to generate error.It is not solved effectively for a long time based on this problem.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, and it is heavy to provide a kind of static test for exempting from datum line beam
Observation device drops, to solve to carry out the big technical problem of static test experimental data error using datum line beam in the prior art.
The utility model is achieved through the following technical solutions:
The utility model provides a kind of static test settlement observer for exempting from datum line beam, which includes connecting two groups more
Logical leveling device group is connected to leveling device group more and is made of respectively multiple more connection leveling devices every group, institute
The more connection leveling devices having pass through conduit respectively and connect with water pipe, the input terminal of the water pipe and automatic water injection tank it is defeated
Outlet connection, each more connection leveling devices pass through cable respectively and connect with data collector, and the data are adopted
Storage is connect with controller, and all more connection leveling devices being connected in leveling device group one group are uniformly mounted on more
All more connection leveling devices being connected in leveling device group at the top of pile foundation, another group are arranged at datum mark more
Locate, jack is installed at the top center of the pile foundation, preloading counter force system, and institute are provided with right above the jack
It states and presses closer the preloading counter force system at the top of jack.
Further, the datum mark is far from the pile foundation.
Further, the more connection leveling devices being arranged in more connection leveling device groups at the top of pile foundation are many
In four, the more connection leveling devices being connected in leveling device group another group are no less than 1 more.
Further, the automatic water injection tank is arranged in datum.
The utility model has the advantage that the utility model provides a kind of static load for exempting from datum line beam compared with prior art
Settlement observer is tested, using multiple more connection leveling devices, is realized not by datum line beam to dead load test on pile foundation
The drawbacks of having detection, avoid datum line beam test, and device is easy to operate, and test data is accurate, greatly improves test
Efficiency and test accuracy rate.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
A kind of a kind of embodiment provided by the utility model referring to FIG. 1-2: static test settlement observation for exempting from datum line beam
Device, which is characterized in that the device includes that leveling device group is connected to two groups more, and leveling device component is connected to every group more
(more 1 perspective views of connection leveling device that the present embodiment uses such as figure are not constituted by multiple more connection leveling devices 1
3), all more connection leveling devices 1 are connect by conduit 2 with water pipe 3 respectively, the input terminal and automatic water filling of water pipe 3
The output end of case 4 connects, and each more connection leveling devices 1 are connect by cable 5 with data collector 6 respectively, data
Collector 6 is connect with controller 7, and all more connection leveling devices 1 being connected in leveling device group one group uniform more
It is mounted on 8 top of pile foundation, all more connection leveling devices 1 being connected in leveling device group another group are arranged at more
Datum is equipped with jack 10 at the top center of pile foundation 8, and the surface of jack 10 is provided with preloading counter force system 9,
And the top of jack 10 presses closer preloading counter force system 9.
