In construction process, testimony personnel should be mixed according to testimony sampling plan sending check, the sampling to construction site and send check to undertake witnessing. Detect the unit should set strictly according to concerned management and technical standard undertakes detecting, examine to what issue the authenticity of the report is responsible, must not alter data the practise fraud in perhaps examining, do not get deregulation to issue examine report.
Basis " housing project and municipal infrastructure project implement testimony sampling and the provision that send check " construction project material without examine orExamine unqualified, must not use.
Material sampling detects is a data member (laboratory technician) function of a job, should reach material entering the arena according to project plan the material sending check of reasonable arrangement, may appear in this one process all sorts of problem, also should know how to be solved, Does special material detect unqualified how to handle?
Material sends check unqualified processing technique:
Most material is in first sampling detects unqualified hind, can have pair of times sampling observation. The material that sends check for the first time namely is a group, detect unqualified hind, can undertake sampling detect again, take times doubler, it is 2 groups send the past to detect. If the 2nd times sampling detects,the result is returned unqualified, explain material has quality problem, that is made namely exeunt processing, material exeunts should have done exeunt proof. Buy raw material entering the arena afresh, also ought to new sampling sends check.
As a result of specific data detect cycle grows quite or major building site detects, if appear at this moment,material detects unqualified and had used, if why be handled?
{! - - PGC_COLUMN- - }From detect station respect contacts processing, do work of good public relations, ensure the report that can take qualification. Present detect the unit is couplet net, detect the result can be in announce for a short while come out, supervise, inspect manage unit also can know to detect result. In material times doubler sampling observation hind is unqualified still, can contact place of design unit field to manage, detect according to current data intensity goes having operation, see safety of whether contented structure, issue design unit proof, design an unit to also want to lose so come corresponding responsibility. Design unit does not wish to come out to help, also can ask tripartite detect the unit has structural safety identification. If final unqualified, can processing of do poorly done work over again.
Fight casting die test specimen to concrete:
Concrete test specimen sends after check is unqualified, can to detect unit application spring back detects, spring back detects unqualified still, application smokes core to detect, the or else that smoke core is eligible: That is quality problem, can undertake filling strong or processing of do poorly done work over again.
Fight casting die test specimen to mortar:
Mortar test specimen is unqualified to detect the station applies for to a string of 1000 cash to detect, defect rework processing, after do poorly done work over again, the spot makes test specimen detect by requirement sampling afresh.
