.
test data soil: it is divided into original soil test and soil compaction test
.
The ring knife sampling part of filling engineering should be backfilled in the lower half of each layer after compaction: 10% of the total number of column foundations should be selected, but not less than 5 foundation trench and pipe trench backfilled: one group of samples should be taken according to the length of each layer of 20 ~ 50m, but not less than one group (3) Site leveling and filling: each layer shall be sampled one group (3 pieces) according to the length of 400 ~ 900m2 Foundation pit and indoor backfill: sample one group of 100 ~ 500m2, but not less than one group (3) The soil quality was sampled according to the type of soil sample, and each soil sample was 20kg
.
Cement and fly ash: cement of the same manufacturer, same grade, same variety, same batch number and continuously entering the site shall be taken as one batch if the bag size is not more than 200t and bulk size is not more than 500t, and each batch shall be sampled at least once
.
When there is doubt about the quality of cement in use or ordinary portland cement has been out of the factory for more than three months, it must be re sampled
.
For different points of bagged cement, 20 bags of cement shall be sampled, each bag shall not be less than 0.5kg, and the cumulative sampling shall not be less than 12kg; One vehicle is taken as a sampling point for bulk cement, and each sampling point shall not be less than 1kg, and the cumulative sampling shall not be less than 12kg
.
Take 200t fly ash continuously supplied with the same grade as a batch, and 8kg steel for each sampling: hot rolled ribbed bar of reinforced concrete, round bar of the same grade and Specification no more than 60t as a batch, and randomly select two steel bars from each batch
.
Stretching: two 40cm bending: two 15cm + 5D (D is the diameter of reinforcement) Carbon structural steel and low alloy high strength steel of the same brand, grade, variety, size and delivery state are considered as one batch Cold rolled ribbed steel bars of the same brand, specification, shape, production process and delivery state of no more than 60t are regarded as one batch, with 2 bending tests for each batch and 1 Tensile test for each batch In the same shift, 300 joints of the same grade and diameter completed by the same welder are drawn in one batch: three 40cm bends; three 15cm + 5D joints are sampled: if the welding quantity is small in the same shift, it will be accumulated in one week; if the accumulated quantity is still less than 300 joints, it will be arc welded in one batch: in the cast-in-place concrete structure, the same grade of steel bars, the same grade of steel bars, the same type of steel bars, the same type of steel bars, the same type of steel bars, the same type of steel bars, the same type of steel bars For the same type of joint, no more than 300 joints shall be regarded as one batch; for the three 40cm steel bars in the building structure, no more than 300 joints of the same grade in the second floor shall be regarded as one batch; for the less than 300 joints, it shall be regarded as one batch; for the building structure, no more than 300 joints of the same grade in the second floor shall be regarded as one batch; for the less than 300 joints, it shall be regarded as one batch Mechanical connection of steel bar: the same construction conditions, the same batch of materials, the same grade, the same type, the same specification, no more than 500 joints as a batch (when less than 500 joints are installed on the same floor on site, it is still a batch)
.
Common brick, hollow brick, aerated block: common fired brick, the same factory, 35000 ~ 150000 pieces of the same specification as a batch, If there are less than 35000 pieces, 12 pieces shall be selected from each batch of qualified samples by random sampling method For hollow bricks of the same manufacturer, 35000-150000 pieces of the same specification shall be regarded as a batch, and those of less than 35000 pieces shall be regarded as a batch 50 thousand pieces of perforated bricks from the same manufacturer are a batch Each manufacturer of small concrete hollow blocks shall inspect at least one group for every 10000 blocks, and no more than two groups shall be used for the foundation and bottom layer of multi-storey buildings Mix proportion: according to different cement varieties, cement delivery date, mortar, concrete characteristics, strength grade and building parts, make a group of concrete mix proportion respectively
.
Cement: 1 bag Stone: 150kg sand: 60kg mortar mix proportion Cement: 20kg sand: 40kg remarks: when the composition and materials of concrete and mortar are changed, the mix proportion of sand and gravel shall be determined again: 400m3 or 600t of the same origin and specification shall be taken as the acceptance batch, and less than 400m3 or 600t shall also be taken as a batch
.
When sampling on the material pile, the sampling parts shall be evenly distributed
.
Remove the surface layer of the sampling part before sampling
.
Then, for the sand, 8 equal samples were taken from each part to form a group of samples
.
For stones, approximately equal 15 samples were taken from each part (five different parts were evenly distributed at the top, middle and bottom of the pile) to form a group of samples.
