Description
Technical field
The invention belongs to architectural engineering pile foundation detection field, more particularly to a kind of Portable Standards beam and its erection side
Method.
Background technology
Nowadays, static test be in current foundation detection it is the most accurate, be also reliably a kind of most commonly seen bearing capacity
The method of inspection, judges whether certain dynamic load method of inspection is ripe, the contrast error size using Static Load Test Results is used as foundation.
The detection of bearing capacity is general using settling amount as criterion, and to carry out settling discharge observation will have geo-stationary
Point, as bench mark in the measurements, datum line beam just plays a part of this sedimentation benchmark in static test, in the examination of whole static load
Datum line beam should not be influenceed by temperature, vibration and other extraneous factors during testing, it is therefore necessary to ensure base in process of the test
The stability of quasi- beam.During actual installation, one end of datum line beam is fixed and its other end free support, though the installation of datum line beam is whole
It is a link the simplest in individual static test installation process, but its installation accuracy is directly connected to whole static test
Success or failure.
But in the prior art, the benchmark beam erection method in dead load test on pile foundation is more random, is largely derived from scene
Raw material, such as sand drift, building block, reinforcing bar shelf, no unified standard, the installation of datum line beam are primarily present asking for the following aspects
Topic：1st, there is rigidity not enough in existing datum line beam, produce larger deflection deformation；2nd, for setting up the temporary stent of datum line beam
Stability is difficult to ensure that the erection stability of datum line beam, easily produces rolling, displacement, sedimentation or produces artificial destruction etc.；3、
In use, benchmark boom support is often due to the problem of support is with ground out of plumb caused by environment or human error factor；4th, base
The length of quasi- beam is fixed, it is impossible to adjusted, when in use, and a kind of applicable scope of datum line beam of length specification is small, to meet specification
It is required that, need to change the datum line beam of corresponding length repeatedly for different pile foundations, it is extremely inconvenient to use.Due to existing benchmark
Beam has that above-mentioned rigidity is inadequate, stability is poor, length violation is closed, and can not meet detection test specification requirement,
So that the data of dead load test on pile foundation collection are affected and produce measurement error.
The content of the invention
The purpose of the present invention be in view of the above-mentioned problems existing in the prior art there is provided one kind it is simple in construction, reasonable in design and
Install and the easy Portable Standards beam of dismounting, the datum line beam has good stability, and can effectively ensure that the installation accuracy of datum line beam,
And ensure the accuracy and precision of static test data result.
